In `@packages/opencode/src/altimate/native/finops/query-history.ts`:
- Line 58: The Postgres path is receiving a SQL string with a literal "LIMIT ?"
because getQueryHistory() is appending POSTGRES_HISTORY_SQL plus [limit] while
the Postgres driver (packages/drivers/src/postgres.ts) ignores _binds; fix by
either (A) rendering the numeric limit into POSTGRES_HISTORY_SQL in
getQueryHistory() so the SQL contains "LIMIT <number>" (keep
POSTGRES_HISTORY_SQL updated) or (B) implement bind support in the Postgres
driver (handle _binds in the code in packages/drivers/src/postgres.ts so it
replaces parameter placeholders with bound values) — pick one approach and apply
it consistently so getQueryHistory(), POSTGRES_HISTORY_SQL and the Postgres
driver agree on binds vs rendered values.

Hey @VJ-yadav — thanks for picking this up! Completing the parameterized binds migration from #277 is exactly what we need. The warehouse-advisor.ts changes are clean and correct. A few things need fixing before we can merge though:
1. SQL template fragmentation (all files except warehouse-advisor.ts)
The GROUP BY, ORDER BY, and LIMIT clauses got moved out of the SQL templates and into JS string concatenation:
// Before — self-contained, readable SQL
const SQL = `... WHERE start_time >= DATEADD('day', ?, CURRENT_TIMESTAMP())
{warehouse_filter}
GROUP BY warehouse_name, DATE_TRUNC('day', start_time)
ORDER BY usage_date DESC, credits_used DESC
LIMIT ?`
// After — SQL split between template and call site
sql: SQL + `${whF}\nGROUP BY warehouse_name, ...\nORDER BY ...\nLIMIT ?\n`Anyone reading the SQL template now sees an incomplete query. The fix: keep GROUP BY/ORDER BY/LIMIT ? in the templates, and only replace the filter placeholders with dynamic concatenation. For example in credit-analyzer.ts:
const SNOWFLAKE_CREDIT_USAGE_SQL = `
SELECT ...
FROM SNOWFLAKE.ACCOUNT_USAGE.WAREHOUSE_METERING_HISTORY
WHERE start_time >= DATEADD('day', ?, CURRENT_TIMESTAMP())
{warehouse_filter}
GROUP BY warehouse_name, DATE_TRUNC('day', start_time)
ORDER BY usage_date DESC, credits_used DESC
LIMIT ?
`
// Then at the call site — only replace the filter placeholder:
sql: SNOWFLAKE_CREDIT_USAGE_SQL.replace("{warehouse_filter}", whF),The {warehouse_filter} placeholder is fine to keep — it's not a SQL injection risk because it's replaced with either "" or "AND warehouse_name = ?" (both hardcoded strings, not user input). The actual user values go through binds. This applies to credit-analyzer.ts, query-history.ts, role-access.ts, and tags.ts.
2. Postgres "no binds" claim — query-history.ts:132
// Postgres driver does not support parameterized binds — render LIMIT inline
return { sql: POSTGRES_HISTORY_SQL + `LIMIT ${Math.floor(Number(limit))}\n`, binds: [] }node-postgres (pg) fully supports parameterized queries with $1 syntax. The comment is incorrect. While Math.floor(Number(limit)) prevents injection here, it's still string interpolation in a PR that eliminates it. Please use a bind parameter instead, or if there's a specific reason our Postgres driver path doesn't support binds, add a comment explaining the actual reason (e.g., referencing which driver/connector class is involved).
3. Minor: empty filters produce \n\n in SQL
When no filters are active, the concatenation produces double newlines:
...WHERE start_time >= DATEADD(...)
\n\nORDER BY...
Not a bug (SQL ignores whitespace), but would be cleaner to filter empty strings or use .filter(Boolean).join("\n").
What's good and can stay as-is
warehouse-advisor.ts— This is the cleanest change. The{days}→?migration with{ sql, binds }return type is exactly right. The call site updates inadviseWarehouse()are correct.- Test updates in
schema-finops-dbt.test.tscorrectly verify the new return types and bind values. - The bind ordering logic (push filter, then push limit) is correct across all files.
TL;DR
The approach in warehouse-advisor.ts is the model to follow. For the other files, keep the SQL templates complete (with GROUP BY/ORDER BY/LIMIT ? inside them), and only use dynamic concatenation for the optional WHERE clause filters. That gives us parameterized binds for all user values while keeping the SQL readable.
Happy to help if you have questions on any of this!
…ceholders Address review feedback on PR AltimateAI#432: 1. Restore GROUP BY, ORDER BY, and LIMIT clauses to SQL template constants so each template is a complete, readable query. Only the optional WHERE filter placeholders ({warehouse_filter}, {user_filter}, etc.) are replaced at the call site via .replace() — safe because they are hardcoded SQL fragments, not user input. 2. Fix incorrect comment in query-history.ts claiming Postgres driver does not support parameterized binds. The actual limitation is that our connector wrapper (packages/drivers/src/postgres.ts) does not yet pass the _binds parameter through to pg. LIMIT is still rendered inline via Math.floor(Number(limit)) until the driver is updated. 3. Double-newline issue from empty filters is resolved by the .replace() approach — replacing an empty placeholder leaves at most a blank line, which SQL ignores.

…binds
Replaces `{days}` string interpolation in warehouse-advisor SQL
templates with `?` positional binds across Snowflake, BigQuery, and
Databricks warehouse-load and warehouse-sizing queries. `buildLoadSql`
and `buildSizingSql` now return `{ sql, binds }` and the call sites
in `adviseWarehouse` pass binds through to `connector.execute()`.
Postgres `{limit}` in query-history is kept as a rendered value with
`Math.floor(Number(limit))` because the Postgres connector's
execute() does not yet forward the `_binds` parameter. Filter
placeholder interpolations elsewhere in finops/schema are left as-is
per review feedback — tracked separately.
- `warehouse-advisor.ts`: 6× `{days}` → `?`, return types updated
- `query-history.ts`: comment clarifies why Postgres stays inline
- `schema-finops-dbt.test.ts`: updated for new `{ sql, binds }` shape
Continues the migration started in AltimateAI#277.
