Julian Hyde commented on CALCITE-4533:
--------------------------------------
[~vozerov], I saw you just changed the type from “improvement” to “bug”. Can
you also please change the description. The description of a bug should
describe the problem, not what you did to fix it, and therefore should almost
never include the word “fix”.
> Fix handling of REPLACE and IF NOT EXISTS keywords for CREATE TABLE/SCHEMA
> commands

> Key: CALCITE-4533

> Issue Type: Bug
> Components: server
> Affects Versions: 1.26.0
> Reporter: Vladimir Ozerov
> Assignee: Vladimir Ozerov
> Priority: Major
> Labels: pull-request-available
> Time Spent: 4h
> Remaining Estimate: 0h

> 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.
