Hi
How would one add this as a derived column
CASE
WHEN Data IS NULL
THEN NULL
WHEN SUBSTRING(REPLICATE('0', 9 - LEN(Data)) + CAST(CYCLE_YYYYMM AS VARCHAR(9)), 4, 6) IS NULL
THEN 0
ELSE RTRIM(SUBSTRING(REPLICATE('0', 9 - LEN(Data)) + CAST(Data AS VARCHAR(9)), 4, 6))
END
From what I have seen the first option is not really required
