Column is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause

I am a newbie in SQL querying; I’m getting this error:

“DESCRIPTION’ is invalid in the select list because it is not
contained in either an aggregate function or the GROUP BY clause”

I can’t find the right aggregate function. I need something like unique(DESCRIPTION) in my select statement

My description column is unique varchar values, any idea?

INSERT INTO myTable2 (ID,INDEX,STATUS,DESCRIPTION,TS)
SELECT ID,min(INDEX),STATUS,DESCRIPTION,min(TS) from myTable2 t1top
WHERE (EXISTS(
        SELECT * FROM myTable1 WHERE ID=t1top.ID AND STATUS='Completed' )) 
GROUP BY ID, STATUS
ORDER BY ID  DESC, STATUS DESC

Answer 1

Add DESCRIPTION to your GROUP BY list, it should work

INSERT INTO myTable2 (ID,INDEX,STATUS,DESCRIPTION,TS)
SELECT ID,min(INDEX),STATUS,DESCRIPTION,min(TS) from myTable2 t1top
WHERE (EXISTS(
    SELECT * FROM myTable1 WHERE ID=t1top.ID AND STATUS='Completed' )) 
GROUP BY ID, STATUS, DESCRIPTION
ORDER BY ID  DESC, STATUS DESC

but that doesn’t mean your query is correct – depends on what you want to achieve
