Magic ETL Help - Overwrite value in a column if another column equals one of two values

swagner

In our sales system there was a recent change to a part number, and I need to correct history in the dataset.  If the 2nd Item Number is either "LOT SQD STOCK" or "LOT SQD SPECIAL" then I want to overwrite the value in the Supplier ID column to be "SQD" otherwise I want the Supplier ID column keep it's current value.

 

I'd like to do this in Magic ETL if I can.

 

Here's the basic logic:

IF 2nd Item Number equals with "LOT SQD STOCK" OR "LOT SQD SPECIAL"

THEN Supplier ID equals "SQD"

ELSE Supplier ID

END

END

Hi, Swagner,

 

Hopefully this is of use for you.

 

- Filter into two tables based on the criteria you mentioned below.

- Add Constant 'SQD' or whatever constant you're going to replace your Supplier ID with. (You have to do it for both tables so you can append at the end.)

- Set column value from your Constant column to overwrite your Supplier ID column for 'LOT SQD STOCK|SPECIAL' table.

- Append.

 

Let me know if you have any questions.

 

Best wishes,

P.S.: You can add in the Select Column function and choose only the columns you need since this method will give you two extra columns from the constanct columns - SQD and Not SQD.

I'm not sure if you can do that via a Magic ETL, but I know you can with a SQL transform. It would just be a case statement like the following:

 

SELECT *, CASE WHEN `2nd Item Number` LIKE '%LOT SQD STOCK%' OR `2nd Item Number` LIKE '%LOT SQD SPECIAL%' THEN 'SQD' ELSE `Supplier ID` END  AS 'New Supplier ID'

FROM table

 

Hope that helps. Let me know if you have any questions.
