--------------------------------------
Summary: Support predicate DELETE for the built-in JDBC V2 catalog
Key: SPARK-60812
URL: https://issues.apache.org/jira/browse/SPARK-60812
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 5.0.0
Reporter: Hemanth Boyina
DELETE FROM a table in the built-in JDBC catalog fails with "table does not
support deletes" because JDBCTable doesn't implement SupportsDeleteV2.
Make JDBCTable support DELETE by compiling the WHERE condition and running a
single DELETE statement on the database. Only translate conditions we can push
down safely: comparisons, IS [NOT] NULL, IN, AND/OR/NOT, with a column compared
to an integer, decimal, or NULL literal. Anything else keeps the old behavior
and fails during analysis without deleting anything.
