They are asking for two different behaviors. Should we reject this kind of query like others ( [1](https://docs.microsoft.com/en-us/azure/databricks/sql/language-manual/sql-ref-syntax-ddl-create-table-using#parameters), [2](https://cloud.google.com/bigquery/docs/reference/standard-sql/data-definition-language#:~:text=collate_specification%5D%0A%5BOPTIONS(schema_option_list)%5D-,Arguments,-IF%20NOT%20EXISTS) )? 'create or replace if not exists' is not supported in MySQL/PG, and is not permitted in databricks. we can have a disscussion about how to deal with it. -- This is an automated message from the Apache Git Service.
