  col2 VARCHAR default
                       !!!RESOLVE EWI!!! /*** SSC-EWI-SY0001 - UNSUPPORTED DEFAULT VALUE LAST USER IN SNOWFLAKE ***/!!!
                       last user,
  col3 VARCHAR default
                       !!!RESOLVE EWI!!! /*** SSC-EWI-SY0001 - UNSUPPORTED DEFAULT VALUE CURRENT PUBLISHER IN SNOWFLAKE ***/!!!

Copy
Generated Code:¶
 CREATE OR REPLACE TABLE T1 (
  DATA VARCHAR
