SELECT SYSDATE FROM DUAL;

Output Default

OUT -> Oracle_02.sql

CREATE OR REPLACE TABLE DATE_TABLE (
        DATE_COL TIMESTAMP /*** SSC-FDM-OR0042 - DATE TYPE COLUMN HAS A DIFFERENT BEHAVIOR IN SNOWFLAKE. ***/
    )
    COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"oracle"}}'
    ;
