### What changes were proposed in this pull request? This PR applies `escapeSql` to the `comment` argument of the JDBC dialect comment query methods: `JdbcDialect.getTableCommentQuery`, `JdbcDialect.getSchemaCommentQuery`, and the `MySQLDialect.getTableCommentQuery` override. ### Why are the changes needed? The `comment` was embedded into a single-quoted SQL literal without escaping, so a comment containing `'` breaks the statement. `escapeSql` doubles single quotes (`'` -> `''`): - Before: `COMMENT ON TABLE t IS 'a'b'` (invalid) - After: `COMMENT ON TABLE t IS 'a''b'` (correct) ### Does this PR introduce _any_ user-facing change? Yes. A table or schema comment containing a single quote is now stored correctly instead of failing with a SQL syntax error. ### How was this patch tested? Pass the CIs with a newly added test case. ### Was this patch authored or co-authored using generative AI tooling?
