Paul Rogers created IMPALA-7868:
-----------------------------------
Summary: Move UPDATE-only fields from ModifyStmt to UpdateStmt
Key: IMPALA-7868
URL: https://issues.apache.org/jira/browse/IMPALA-7868
Project: IMPALA
Issue Type: Improvement
Components: Frontend
Affects Versions: Impala 3.0
Reporter: Paul Rogers
Assignee: Paul Rogers
A subset of the FE parse node hierarchy:
{noformat}
ParseNode
|- StatementBase
|- ModifyStmt
|- DeleteStmt
|- UpdateStmt
{noformat}
The {{ModifyStmt}} holds a number of members that are used only by the
{{UpdateStmt}}, but which make no sense fr the {{DeleteStmt}}.
This ticket asks to rationalize the class structure, moving {{UPDATE}}-only
fields to the {{UpdateStmt}} class.
