Using rs.RecordCount - Get -1 ( minus one) value everytime.....

Hi , im using ASP with VBScript and Mysql

I didnt have a problem when the db was MS access but now have started using it with MySQL..

This is Code for record set...

rs.CursorType = 3
rs.Open strSCat, strConn
rc = rs.RecordCount
response.write rc

Rc value giving me "-1" every time....

Have tried using

rs.Open strSCat, strConn,3,3
rc = rs.RecordCount
response.write rc

but get

2 (This is the value which is correct!)
Microsoft Cursor Engine error '80004005'

Key column information is insufficient or incorrect. Too many rows were affected by update.

/category.asp, line 73


any ideas?

Cheers

Stephen
