----------------------------------
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.
