-----------------------------------
Summary: Remove the unneeded conversion from Statement to
LogicalPlan for DELETE/UPDATE
Key: SPARK-29835
URL: https://issues.apache.org/jira/browse/SPARK-29835
Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 3.0.0
Reporter: Xianyin Xin
The current parse and analyze flow for DELETE is: 1, the SQL string will be
firstly parsed to `DeleteFromStatement`; 2, the `DeleteFromStatement` be
converted to `DeleteFromTable`. However, the SQL string can be parsed to
`DeleteFromTable` directly, where a `DeleteFromStatement` seems to be redundant.
It is the same for UPDATE.
