----------------------------------------
Summary: Fix handling of REPLACE and IF NOT EXISTS keywords for
CREATE TABLE/SCHEMA commands
Key: CALCITE-4533
URL: https://issues.apache.org/jira/browse/CALCITE-4533
Project: Calcite
Issue Type: Improvement
Components: server
Affects Versions: 1.26.0
Reporter: Vladimir Ozerov
Assignee: Vladimir Ozerov
Presently, the {{ServerDdlExecutor}} incorrectly process some keywords:
# {{CREATE SCHEMA IF NOT EXISTS}} overwrites the existing schema
# {{CREATE OR REPLACE TABLE}} doesn't replace the table if the table exists
The goal of this ticket is to unify the handling of {{IF NOT EXISTS}} and
{{REPLACE}} keywords for these two commands.
