Help, please @WikiRik |
|
@dorlanpabon the change looks good, but it would be better if you could add an integration test as well to reproduce the error you mention in the description. Could you add that? |
Yes |

…ames Adds the integration test requested in review. Two schemas each define a table of the same name with a commented column at the same ordinal position, which is what made the "Comment" subquery return more than one row. The assertion checks that each schema gets *its own* comment rather than just that the call does not throw: when only one of the two tables carries a comment the subquery returns a single row, so the query succeeds while silently reporting the other schema's comment. A "does not throw" test would pass against that bug.

- Line 101: Extend the existing describeTable integration test to assign
distinct comments to corresponding columns in the same-named public and
test_meta tables, then assert each schema’s returned column comment. Update the
test around describeTable so it verifies schema-qualified comment resolution and

Pull Request Checklist
describe-table-query.test.tsfile to cover the new change.Description of Changes
This PR adds a condition to the SQL query generated by Sequelize for
describeTableQueryin PostgreSQL. The conditionAND c.table_schema = st.schemanameis added to the subquery that retrieves column comments. This solves the issue where multiple schemas with tables of the same name caused the subquery to return more than one row, leading to the error:This change ensures that the subquery retrieves results only from the correct schema, avoiding conflicts in databases with multiple schemas.
List of Breaking Changes
No breaking changes. This PR simply adjusts a subquery for more precise query generation in PostgreSQL.
Thanks to @nachocab for the previous work on this issue in PR #12568. The current PR builds upon the valuable solution provided there, specifically addressing the subquery error in PostgreSQL when handling multiple schemas. The fix introduced, adding a condition to ensure only the correct schema is queried, continues to improve query precision and avoid errors in complex database environments. Your contribution laid the groundwork for this improvement, and it’s highly appreciated!
Summary by CodeRabbit
describeTablenow returns the column comments belonging to the requested schema, improving accuracy when tables share names across schemas.
