Severity

Low

Description

Snowflake does not operate transaction label names because there should not be nested transactions to identify in different COMMIT or ROLLBACK statements.

Example code

Input Code:

CREATE PROCEDURE TestTransaction
AS
BEGIN
    DROP TABLE IF EXISTS NEWTABLE;
    CREATE TABLE NEWTABLE(COL1 INT, COL2 VARCHAR);
      BEGIN TRANSACTION LabelA;
        INSERT INTO NEWTABLE VALUES (1, 'MICHAEL');
        INSERT INTO NEWTABLE VALUES(2, 'JACKSON');
      COMMIT TRANSACTION LabelA;
END

Output Code:

CREATE OR REPLACE PROCEDURE TestTransaction ()
RETURNS VARCHAR
LANGUAGE SQL
EXECUTE AS CALLER
AS
$$
    BEGIN
        DROP TABLE IF EXISTS NEWTABLE;
        CREATE OR REPLACE TABLE NEWTABLE (
            COL1 INT,
            COL2 VARCHAR
        );
            BEGIN TRANSACTION
-- ** MSC-WARNING - MSCEWI1101 - COMMENTED OUT TRANSACTION LABEL NAME BECAUSE IS NOT APPLICABLE IN SNOWFLAKE **
--                              LabelA
                                    ;
            INSERT INTO NEWTABLE VALUES (1, 'MICHAEL');
        INSERT INTO NEWTABLE VALUES(2, 'JACKSON');
            COMMIT;
    END;
$$;
