Howdy all,

I'm getting a "3800: DataType mismatch in THEN/ELSE expression" error, on my COALESCE part of a query.

The problem query is similar to this:

     SELECT
       A.PI_Column1
       ,A.PI_Column2
       ,COALESCE( MIN( B.CHAR_20_FIELD ), 'String Literal')  AS Attrib1
     FROM
       DB.Table  A
     LEFT OUTER JOIN
       DB.Table  B
     ON (A.PI_Column1 = B.PI_Column1
     AND A.PI_Column2 = B.PI_Column2)
     GROUP BY 1,2,3
     ;

Any insights as to why COALESCE does not like my MIN()? I can't find the SQL right now, but I'm sure I've done this MIN() logic in a COALESCE before.

Thanks,

Anomy
