[jira] [Created] (SPARK-32523) Override alter table in JDBC dialects

Huaxin Gao created SPARK-32523:
----------------------------------

             Summary: Override alter table in JDBC dialects
                 Key: SPARK-32523
                 URL: https://issues.apache.org/jira/browse/SPARK-32523
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.1.0
            Reporter: Huaxin Gao


SPARK-32402 adds new method alterTable to JdbcDialect with the default implementation for add column, rename column, delete column, update column type, update column nullability. However, different database servers may have different syntax for these update table commands. This ticket aims to override the default alter table syntax with the correct ones in all JDBC dialects.
