             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.
