SQL Syntax Error when using DB2

My version of DB2 Express (v10.5.0.420) does not like the syntax "[...] count(RES.*) [...]" and gives me a syntax error (SQLCODE=-104, SQLSTATE=42601) when I try to open the reports tab. As soon as a take the prefix ("RES.") out of the statement, it works perfectly fine.

As far as I can see, the prefix is not necessary for the statement, so I would suggest to just drop it, provided that this does not cause problems when using other DBMS, which I cannot assess.

Please feel free to approach me with any questions concerning this matter and / or correct / drop this request if you have a better solution.

Thank you!
