    Posted: 25 April 2003 at 1:21am

The following didn't work. Why??

strSQL = "SELECT tblNewsRating.News_ID, Avg(tblNewsRating.Rating) AS MediadiRating "
strSQL = strSQL & "FROM tblNewsRating "
strSQL = strSQL & "GROUP BY tblNewsRating.News_ID "
strSQL = strSQL & "WHERE tblNewsRating.News_ID = " & rsnews("News_ID") &";"

That's the error message:

Tipo di errore:
Microsoft JET Database Engine (0x80040E14)
Errore di sintassi (operatore mancante) nell'espressione della query 'tblNewsRating.News_ID WHERE tblNewsRating.News_ID = 117'.
/Ticinorally/testing2.asp, line 52

thanks to all for the help

Sorry I have found now the solution. And for all that have the same problem, here you have the solution:

strSQL = "SELECT tblNewsRating.News_ID, Avg(tblNewsRating.Rating) AS MediadiRating "
strSQL = strSQL & "FROM tblNewsRating "
strSQL = strSQL & "GROUP BY tblNewsRating.News_ID "
strSQL = strSQL & "HAVING tblNewsRating.News_ID = " & rsnews("News_ID") &";"

If you work with a Group you must use Having and not Where.

actually thats not true, you can have

SELECT.. FROM .. WHERE... GROUP

"having" isn't absolutely required

OK but with the WHERE command the SQL didn't work and with HAVING it works. Why?
