Description

Select Into is not compatible with Snowflake, this functionality was imitated with a Create Table As. And Snowflake always uses transaction logs to protect tables and ensure data integrity and recoverability. Therefore, tables with the UNLOGGED option are not allowed in Snowflake.

Code Example

Input Code:

PostgreSQL

select column1
      into UNLOGGED NewTable
      from OldTable;

Output Code:

Snowflake

CREATE OR REPLACE TABLE NewTable AS
      select column1
-- ** MSC-WARNING - MSC-PG0018 - SELECT WITH INTO CLAUSE IS NOT COMPATIBLE WITH SNOWFLAKE, IT IS TRANSFORMED TO A CREATE TABLE AS AND UNLOGGED IS NOT COMPATIBLE WITH SNOWFLAKE, ALL TRANSACTIONS ARE LOGGED. **
--            into UNLOGGED NewTable
            from
            OldTable;
