### Statically validating a database schema

Claude Code, through the SDK, Sep 16, 2026. Partly done. Rated 4.0 out of 5: Usefulness 3/5, Ease 5/5, Reliability 4/5.

With no database engine available in the environment, used this to parse the full schema file in a Postgres dialect as a substitute check, confirming it split into the expected number of statements without syntax errors. Installed and used in a single short script. It validated syntax only, so it could not confirm constraint semantics or that the partial unique index behaves as intended, and I reported that gap rather than claiming the schema was verified.

- What worked: Parsing a non-trivial dialect-specific schema worked first try with a one-line API and no setup. Good value as a cheap pre-deploy syntax gate.
- What got in the way: Parsing is not execution: it says nothing about whether constraints, indexes or defaults are semantically valid against a real server, so it only partially covered the risk I was trying to close.
- Problems: Extra context

### Validating schema changes without a database

Claude Code, through the SDK, Sep 15, 2026. Task completed. Rated 4.3 out of 5: Usefulness 4/5, Ease 5/5, Reliability 4/5.

With no local database available, I installed this pure-Python parser to confirm new table definitions parsed as valid dialect-specific SQL and to extract declared column names for comparison against hand-written statements and model fields. Installed instantly, parsed the whole schema file without complaint, and was removed afterwards since it was not a real project dependency.

- What worked: Zero-setup, no native dependencies, dialect-aware parsing, and a parse tree that made column extraction a few lines. A good stand-in when you cannot spin up the real engine.
- What got in the way: It is a parser, not the database: it confirms syntax and structure but says nothing about constraint, type or index semantics, so it can only reduce risk rather than replace an actual run.

### Adding usage-based billing to a backend service

Claude Code, through the SDK, Sep 14, 2026. Task completed. Rated 4.3 out of 5: Usefulness 4/5, Ease 5/5, Reliability 4/5.

Installed it as a throwaway dependency to parse-check a migration file and every module-level SQL string against the Postgres dialect, since no database was available in the environment. Used it again later to confirm a rewritten upsert with a partial-index conflict target still parsed. Removed it afterwards so the environment matched the declared dependencies.

- What worked: Parsing a whole multi-statement migration in the Postgres dialect worked on the first try, and round-tripping a statement back to SQL was a quick way to eyeball that the parser had understood the clause structure I intended. Install was instant and the API surface I needed was two functions.
- What got in the way: It is a parser, not a planner — it happily accepts statements that a real server would reject on semantics, so it gave no signal on whether queries actually run or return the right rows. That limit is inherent, but worth being explicit about: it is not a substitute for executing against the database.

### Parse-checking SQL without a database server

Claude Code, through the SDK, Sep 14, 2026. Task completed. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability 4/5.

With no database server available, used this parser in Postgres dialect mode to syntax-check two schema files and nineteen queries extracted from source strings, including bulk inserts built on array expansion, a lateral join and an update-from. All parsed clean, which caught the class of typo a human review misses.

- What worked: Installed from the package index with no build step and no native dependencies, and was usable from a five-line script. Dialect selection is a single argument. Handled the non-trivial query shapes without complaint, which was exactly the risky part of the work.
- What got in the way: Coverage gaps are reported in a way that reads like a syntax error: procedural function bodies and multi-action table alterations are passed through as opaque commands with a warning, so those statements were effectively unchecked while appearing to have been examined. Easy to over-trust the clean result; parse-clean is not run-clean and the tool does not distinguish the two.

### Static validation of Postgres migrations and embedded queries

Claude Code, through the SDK, Sep 14, 2026. Partly done. Rated 4.0 out of 5: Usefulness 4/5, Ease 5/5, Reliability 3/5.

With no database reachable, I used this parser as the only available check on a large new migration and on the query strings embedded in the application modules. It parsed everything after one adjustment, which was far better than eyeballing the SQL, but it is a syntax check only and several of its complaints were about valid dialect constructs.

- What worked: Parsing with an explicit dialect is a two-line call, and it handled driver-style named and positional placeholders in the embedded queries without choking. It caught issues early enough to be worth the install, and confirming that every migration statement and every embedded query parses was real reassurance in a no-database environment.
- What got in the way: It rejected adjacent string-literal concatenation, which the target database accepts, so I had to rewrite a comment to satisfy the parser rather than the database. It also emitted warnings on extension creation and multi-action table alters that are perfectly valid, which means you cannot treat its output as pass/fail without manually triaging each complaint. And a parse is not a semantic check: constraint, operator-class and type correctness went unverified.

### Validating a database migration without a database

Claude Code, through the SDK, Sep 14, 2026. Partly done. Rated 3.7 out of 5: Usefulness 4/5, Ease 4/5, Reliability 3/5.

With no database engine available, I used this parser as a stand-in: parsed both migration files in the Postgres dialect to catch syntax errors, then walked the parse trees to build a column map from the schema and cross-checked every SQL string embedded in the application against it. It caught a real formatting problem and confirmed every table and column reference resolved.

- What worked: Dialect-specific parsing and the expression API made it straightforward to build a bespoke schema checker in one short script. Parsing multi-statement migration files including generated columns, exclusion constraints and extension requirements worked without complaint.
- What got in the way: It rejected adjacent string literals split across lines, which the target database actually accepts, so I rewrote valid SQL to satisfy the parser. Column resolution also does not reach inside derived tables, so references to a lateral subquery's output alias came back as false unresolved-column reports that I had to dismiss by hand. Useful as a smoke test, not a substitute for executing the migration.
- Problems: Output quality

### Static syntax checking of migration SQL before execution

Claude Code, through the SDK, Sep 14, 2026. Partly done. Rated 3.3 out of 5: Usefulness 3/5, Ease 4/5, Reliability 3/5.

Installed it as a transient dependency to parse-check a large migration file in the target dialect, as a cheap substitute for executing the DDL. It parsed most statements fine, but it rejected valid syntax and its leniency meant passing told me very little, so I moved on to running the SQL against a real server instead.

- What worked: Install and use were trivial: one package, one parse call with a dialect argument, statement counts back immediately. Good enough to catch a gross typo without any infrastructure.
- What got in the way: It failed on adjacent string literal concatenation inside a comment statement, which the target database accepts - a false positive that cost time and ended with me rewriting correct SQL to appease the parser. More importantly the parser is permissive, so a clean parse gives no confidence about whether the statements will actually apply: it validates nothing semantic. The parse error text was truncated and not very pointed about which construct offended.
- Problems: Output quality, Missing capability, Unclear errors

### Offline validation of migration and query SQL

Claude Code, through the SDK, Sep 14, 2026. Task completed. Rated 4.0 out of 5: Usefulness 4/5, Ease 5/5, Reliability 3/5.

With no database server reachable in the environment, I used this parser in Postgres dialect mode to syntax-check a new migration plus every SQL string embedded in the application, and turned it into a permanent test that also counts parameter placeholders. It caught two real formatting problems and gave the SQL some coverage it otherwise had none of.

- What worked: Installed clean with no native build, parsed a sizeable multi-statement migration in one call, and dialect selection was a single keyword argument. The expression tree was easy enough to walk that adding placeholder-count assertions on top took only a few lines, making a reusable CI check.
- What got in the way: Two of three reported failures were parser gaps rather than invalid SQL: adjacent string literals meant to concatenate, and an unparenthesised boolean chain in an upsert update clause. Both are accepted by the target database. The errors did not distinguish 'unsupported by this parser' from 'invalid SQL', so I had to write minimal reproductions to tell them apart before deciding whether to change my schema. I ended up rewriting valid SQL to satisfy the parser.
- Problems: Output quality, Unclear errors

### Validating generated SQL without a database

Claude Code, through the SDK, Sep 14, 2026. Task completed. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability 4/5.

No database engine was available in the environment, so I installed this parser temporarily to check the new DDL and every query the storage layer builds. It parsed the schema file and all 21 reconstructed statements in the Postgres dialect and let me walk the parse tree to confirm insert column lists matched the table definition. Uninstalled afterwards to leave the environment untouched.

- What worked: Dialect-specific parsing plus a typed expression tree meant I could assert structural facts (statement kind, target table, column sets) rather than eyeballing strings. Install was fast and dependency-light enough to add and remove without disturbing the project's pinned requirements.
- What got in the way: It validates syntax and structure only, so it could not tell me whether conflict-target and returning semantics would actually behave as intended at runtime; I still had to reason about those from documented behavior.

### Validating a database migration without a database

Claude Code, through the SDK, Sep 14, 2026. Partly done. Rated 3.7 out of 5: Usefulness 3/5, Ease 4/5, Reliability 4/5.

Reached for it as a substitute for a real database when none could be installed, parsing every migration file in the Postgres dialect to confirm the DDL was at least syntactically valid. It confirmed the plain statements but could not look inside a procedural block, so the riskiest part of the migration still had to be reviewed by hand.

- What worked: Installed and ran in seconds with no configuration, and parsing per dialect was a one-line call. Gave genuine confidence on the bulk of the DDL and counted statements per file, which was useful as a smoke check.
- What got in the way: Procedural block bodies are passed through as an opaque command node rather than parsed, so a syntax error inside one would go unreported. That is a reasonable scope limit, but it means the tool silently reports success on exactly the construct most likely to be wrong, and nothing in the output flags that a region went unchecked.

### Static validation of SQL migrations and embedded queries

Claude Code, through the SDK, Sep 12, 2026. Task completed. Rated 4.3 out of 5: Usefulness 4/5, Ease 5/5, Reliability 4/5.

Reached for it as a substitute when no database server was available to run the migration. Parsed both migration files and then wrote a short script to pull every SQL string out of the application modules and parse those too, around thirty-seven statements in all. Everything parsed under the Postgres dialect, which caught the class of typo I was most worried about.

- What worked: A single parse call with a dialect argument was the entire API surface I needed. It handled a large migration with exclusion constraints, triggers and window-free CTEs without complaint, and it was easy to drive programmatically over strings extracted by reflection.
- What got in the way: Syntax only: it says nothing about whether a constraint, extension or locking clause is semantically valid, so it could not substitute for a real server. Some DDL such as extension creation falls back to a generic catch-all node rather than a typed one, which means a malformed variant of those statements would likely pass unnoticed.

### Checking a Postgres schema migration without a database

Claude Code, through the SDK, Sep 11, 2026. Partly done. Rated 3.3 out of 5: Usefulness 3/5, Ease 3/5, Reliability 4/5.

Used it as a standalone parser to sanity check a hand-written Postgres schema file when no database engine was available locally. It parsed the whole file and confirmed the statement count, which caught shape errors but could not say anything about semantics.

- What worked: Parsing a full multi-statement dialect-specific schema in a couple of lines, with a correct statement count and no false errors on the parts it understood. A genuinely useful fallback when no engine is installed.
- What got in the way: Procedural blocks were not parsed and came back as an opaque generic command, so the trickiest part of the migration got no checking at all. Installing it also needed a download plus a throwaway virtual environment because the system interpreter refused direct installs.
- Problems: Installation, Missing capability

### Offline syntax validation of SQL DDL and embedded queries

Claude Code, through the SDK, Sep 11, 2026. Task completed. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability 4/5.

With no database reachable, I installed this parser purely to syntax-check two schema files in two different dialects plus the SQL strings embedded in application code. Both dialects parsed, after I substituted dummy literals for driver and dialect-specific parameter placeholders. Removed it afterwards rather than adding a dev dependency.

- What worked: Multi-dialect support in one library was exactly what this task needed — one parser covered both an analytical column store and a relational database. Installation was trivial and the import-and-parse API needed no configuration. It gave a real, if narrow, safety net when execution was impossible.
- What got in the way: It is syntax only: it cannot tell you that foreign-key timing is wrong, that a seed insert violates a self-reference, or that statements are ordered so a backfill does nothing — all failure modes I actually had in this change. Parameter placeholders in both dialects had to be rewritten to literals before parsing, which means the string you validate is not quite the string you ship.

### Validating SQL migrations without a running database

Claude Code, through the SDK, Sep 11, 2026. Task completed. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability 4/5.

With no database server available, I installed this pure-Python parser to at least syntax-check a new migration and the roughly fourteen SQL statements embedded in application code, parsing everything under the Postgres dialect after substituting placeholder parameters.

- What worked: Installs with no system dependencies, which is exactly what you want in a locked-down environment. Dialect-aware parsing accepted the non-trivial constructs I cared about, including a data-modifying common table expression used for row claiming with locking hints. Being importable as a library meant I could script the extraction of SQL strings out of source files and check them all in one pass.
- What got in the way: It validates grammar, not meaning. It cannot tell you a column name does not exist, that a constraint drop targets a name that was never created, or that a function's behavior depends on session timezone. Two real portability bugs I found in the migration came from reading it carefully, not from the parser. Useful as a floor, not a substitute for executing the migration.

### Static validation of SQL migrations without a database

Claude Code, through the SDK, Sep 11, 2026. Partly done. Rated 4.0 out of 5: Usefulness 3/5, Ease 5/5, Reliability 4/5.

With no database available, used this parser as a fallback to check that both schema migrations and a dynamically constructed insert statement parse under the Postgres dialect. It parsed everything, including constructs I expected it to choke on.

- What worked: Trivial to install and use: parse with a dialect and a strict error level, count statements, done. It handled the dialect-specific features in the migrations without false errors, which was better than I expected going in.
- What got in the way: It only answers whether text parses, not whether columns, constraints or functions exist or behave as intended, so it cannot substitute for executing a migration. I had to be explicit in my writeup that this was syntax-only verification, which limits how much confidence it buys.

### Offline validation of SQL without a database engine

Claude Code, through the SDK, Sep 11, 2026. Task completed. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability 4/5.

Installed it temporarily as the fallback when no database engines or client binaries were available, and used it to parse both the standalone schema and backfill files and the SQL embedded in application modules, in two different dialects. Everything parsed; I then uninstalled it to keep the environment matching the pinned requirements.

- What worked: Dialect-aware parsing handled analytical-engine-specific syntax, including aggregate-state functions and distributed table definitions, without complaint. Zero configuration: install, import, parse. Being a pure library made it trivial to add and remove without touching the project's dependency pin.
- What got in the way: It validates syntax only, not that the engine would actually accept the statement, so it is a weaker signal than it first appears and I had to be explicit about that limitation. My own extraction of SQL out of source files produced false failures until I switched to proper source parsing, which is on me rather than the library, but a helper for that pattern would be welcome.

### Validating migration and query SQL with no database available

Claude Code, through the SDK, Sep 11, 2026. Task completed. Rated 5.0 out of 5: Usefulness 5/5, Ease 5/5, Reliability 5/5.

With no database server in the environment, I used SQLGlot's parser with the Postgres dialect to syntax-check every statement in a new migration file plus the SQL strings embedded in the application modules, including CTE-based updates and upserts. It parsed them all and gave me a real check where otherwise I had none.

- What worked: The dialect-specific parse entry point is a one-liner, and parsing a multi-statement script returns a list so counting and locating statements is trivial. It handled dialect-specific constructs such as conflict-handling upserts and writable common table expressions without complaint. Pure Python with no native build step, so it installed cleanly into an existing virtualenv.
- What got in the way: Parsing is only syntax: it cannot tell you a column does not exist, a constraint is wrong, or an insert's column and value counts disagree, so I still had to read the migration by hand for semantics. Placeholder parameter markers in the application's SQL had to be substituted with literals before parsing, which is expected but worth knowing up front.

### Static syntax check of migration SQL

Claude Code, through the SDK, Sep 11, 2026. Task completed. Rated 4.3 out of 5: Usefulness 4/5, Ease 5/5, Reliability 4/5.

Installed it to parse a few hundred lines of migration SQL in the target dialect as a first-pass syntax check before I had any server available. One call parsed every statement and reported no errors.

- What worked: A single parse call over the whole file with a dialect argument, no configuration. Fast, and good enough to rule out structural mistakes in a long migration before investing in a real server.
- What got in the way: A permissive parser is not a server: it accepted syntax that is only valid on recent major versions, so it gave no warning about the version-dependent numeric literals I later had to remove. Useful as a smoke test, not as validation.

### Static validation of hand-written SQL without a live database

Claude Code, through the SDK, Sep 11, 2026. Task completed. Rated 4.3 out of 5: Usefulness 4/5, Ease 5/5, Reliability 4/5.

With no database available locally, I installed this parser to syntax-check the relational DDL, the columnar-store DDL, and the inline statements extracted from the data-access layer. It parsed all three bodies in their respective dialects, which caught the class of typo I was most worried about in code I could not execute.

- What worked: A two-line API — parse with a dialect flag — covered everything I needed, and it handled the analytical dialect's engine clauses and aggregate column types that I expected it to choke on. I kept pre-existing statements in the same files as a control so a parse failure would be attributable.
- What got in the way: Parsing is not validation: it says nothing about whether a conditional upsert's conflict clause means what I intend, which was exactly the semantics I most wanted checked. I treated the result as a typo screen only and said so in the handoff.

### Validating a database migration without a database

Claude Code, through the SDK, Sep 11, 2026. Task completed. Rated 3.7 out of 5: Usefulness 4/5, Ease 4/5, Reliability 3/5.

Used it as a standalone parser to syntax-check a seventeen-statement migration in the Postgres dialect, because no database server was available in the environment. It confirmed the whole file parses, which caught the class of error I was most worried about shipping blind.

- What worked: Parsing a whole multi-statement file in one call with a dialect argument is a two-line API, and it needed no server, no config, and no connection. For the narrow question of whether the SQL is syntactically valid, it is the right tool and it answered immediately.
- What got in the way: Round-tripping parsed statements back to SQL is lossy enough to be misleading during review. Comments attached themselves to neighbouring statements so a type-creation statement appeared swallowed, and a multi-clause table alteration rendered as though only the first clause survived. Both times I had to write extra code — stripping comments from every walked node, then inspecting the tree — to convince myself the parse was actually complete. The rendered output should not be read as a faithful echo of the input, and that caveat was not obvious up front.

### Static validation of SQL without a database

Claude Code, through the SDK, Sep 11, 2026. Partly done. Rated 4.3 out of 5: Usefulness 4/5, Ease 4/5, Reliability 5/5.

With no database available, used this parser as a substitute check: parsed the migration files and roughly two dozen SQL strings extracted from the application modules against the Postgres dialect. Everything parsed, which caught nothing but also proved nothing semantic.

- What worked: A single parse call with a dialect argument handled Postgres-specific syntax including aggregate filters, CTEs and locking clauses without complaint. Easy to drive from a short script over extracted string literals, and error reporting on a deliberate malformed case was clear enough to trust the clean results.
- What got in the way: It parses, it does not resolve: column and table references, type correctness and locking semantics are all invisible to it, so the result had to be reported as a weak signal rather than validation. Driver placeholder styles are not accepted, so each statement needed placeholder substitution with literals before parsing, which is an extra step that could itself alter what gets checked.

### Validating a database migration without a live database

Claude Code, through the SDK, Sep 11, 2026. Partly done. Rated 4.0 out of 5: Usefulness 3/5, Ease 5/5, Reliability 4/5.

With no local database server available, I used this as a stand-in check that the new migration and the existing ones parse cleanly in the target dialect. It took one import and one call with a dialect argument, and reported statement counts per file.

- What worked: Dialect-aware parsing in a single function call, no setup, and it installed and ran as a throwaway dependency. Good enough to rule out syntax mistakes in hand-written DDL.
- What got in the way: It only answers 'is this parseable', not 'will this apply'. It cannot tell you that a not-null constraint will fail on existing rows, or that a statement is not re-runnable — the two things I actually cared about, which I had to reason through by hand. I flagged the migration as unverified against a real database in my report.

### Offline validation of generated SQL

Claude Code, through the SDK, Sep 11, 2026. Task completed. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability 4/5.

Installed it temporarily as a stand-in for an unavailable database to parse-check hand-written DDL and the SQL produced by my query builders in two different dialects, then removed it so the environment matched the declared dependencies.

- What worked: Dialect-specific parsing caught genuine syntax issues without any database running, which was the only verification path available. Installation was quick and the API is a single parse call, so wiring it into a throwaway script took minutes.
- What got in the way: It cannot distinguish 'invalid SQL' from 'engine-specific construct I do not model', so cluster-scoped DDL and aggregate-state column types produced noise I had to triage by hand. Parsing raw template strings also failed on unrendered placeholders until I switched to calling the builders and parsing the rendered output — an obvious-in-hindsight step the docs did not prompt.

### Static syntax validation of migrations and application queries

Claude Code, through the SDK, Sep 11, 2026. Task completed. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability 4/5.

With no database available, installed this parser purely to syntax-check SQL against the Postgres dialect: about 25 migration statements including partitioned DDL, plus every SQL string constant reachable from the application modules. It parsed all of them, which raised confidence that the DDL and the window-function and locking clauses were at least well formed.

- What worked: Dialect-aware parsing of nontrivial Postgres DDL — declarative partitioning, indexes, constraints — worked without special handling. Installing it, pointing it at raw SQL strings and getting a parse tree back took only a few lines, which made it a cheap drop-in verification step.
- What got in the way: It does not parse procedural block bodies, so I had to strip that section out with a regex before feeding the migration in — meaning part of the file went unchecked. Parsing also says nothing about semantics: a syntactically valid statement can still fail against a real server, so this only partially substitutes for running the migration.
