Query to create a condition on a database

Hi everyone, I would like to know how is the syntax to create a condition column (if) on a database, for example:

The column "PPG" already exists and i want to create the column "Gr" with this information.

If PPG = "MPA 90GRS" then Gr should appear "90".

Could someone help me with this calculated column, please?

    Hi @luizalauretti

    you can easily created a beastmode case statement as

    CASE 
        WHEN `PPG` = 'MPA 90GRS' THEN 90
        WHEN `PPG` = 'CTA 90GRS' THEN 90
    END
    

    Adding as many conditions as you want individually or this is another option

    CASE
        WHEN `PPG` IN ('MPA 90GRS', 'CTA 90GRS') THEN 90
        WHEN `PPG` = 'CLUMINOUS 70GRS' THEN 70
    END
    

    now if , PPG contains a lot distinct values , you could ETL a table with those values and join it to your data.

    anyways, there is a lot different ways to do that. hope this helps
