What about this:
lconn = SQLSTRINGCONNECT("DRIVER=SQL Server;SERVER=SQLSERVER;UID="+tUID+";PWD="+tPWD+";WSID=&tWSID;DATABASE=RAG")

>Can i pass parameter in the connection string of a CursorAdapter
>If i try to do This
>tUID = 'Sebastien'
>tPWD='datadis'
>tWSID='SEBASTIEN'
>
>lconn = SQLSTRINGCONNECT("DRIVER=SQL Server;SERVER=SQLSERVER;UID=&tUID;PWD=&tPWD;;WSID=&tWSID;DATABASE=RAG")
>Lconn = 2 So it Work
>
>But if i put the same string in the Connection string of the CursorAdapter Builder i got this error
>Connectivity error :[Microsoft][OBDC sql driver]Login failed for user '&tUID'
