Sample Source Patterns

Input Code:

Redshift

IN -> Redshift_01.sql

CREATE OR REPLACE PROCEDURE simple_loop_when(x int)
LANGUAGE plpgsql
AS $$
DECLARE i INTEGER := 0;
BEGIN
  <<simple_loop_when>>
  LOOP
    RAISE INFO 'i %', i;
    i := i + 1;
    EXIT simple_loop_when WHEN (i >= x);
  END LOOP;
END;
$$;   

Output Code:

Redshift

OUT -> Redshift_01.sql

CREATE OR REPLACE PROCEDURE simple_loop_when (x int)
RETURNS VARCHAR
LANGUAGE SQL

AS $$
    DECLARE
      i INTEGER := 0;
BEGIN
      --** SSC-PRF-0008 - PERFORMANCE REVIEW - LOOP USAGE **
  LOOP
        CALL RAISE_MESSAGE_UDF('INFO', 'i %', array_construct(:i));
    i := i + 1;
        IF ((:i >= : x)) THEN
          EXIT simple_loop_when;
        END IF;
  END LOOP simple_loop_when;
END;
