ASF GitHub Bot updated SPARK-57960:
-----------------------------------
Labels: pull-request-available (was: )
> Escape table and schema identifiers in JDBC dialect index metadata queries
> --------------------------------------------------------------------------
>
> Key: SPARK-57960
> URL: https://issues.apache.org/jira/browse/SPARK-57960
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 5.0.0
> Reporter: Peter Toth
> Priority: Major
> Labels: pull-request-available
>
> PostgresDialect.indexExists and H2Dialect.indexExists/listIndexes embed the
> table (and, for H2, schema) name into a SQL string literal in the pg_indexes
> / INFORMATION_SCHEMA lookup query without escaping. A table or schema name
> containing a single quote therefore produces a malformed query that fails
> with a syntax error. This is inconsistent with the index name in the same
> methods, which is already escaped via escapeSql (SPARK-57446 / SPARK-57447).
> Fix: apply escapeSql to the table/schema identifiers at these sites so
> quote-containing identifiers work correctly. (MySQLDialect.indexExists places
> the table in identifier position via quoteIdentifier and is already correct.)
