>I have a table in our SQL Server database which holds the next available key for each table. When retrieving the next key I call the function below. It worked great while I was the only one logged in. Now we have testers in the system and I am receiving Table Update errors. It's my understanding that remote views can only be optimistically locked. Is that true? How could I do a SEEK...RLOCK...REPLACE...UNLOCK?

Row locking in SQL 6.5 not available, however it will be available in SQL 7.0

I suggest that you add (NOLOCK) to your select statement.

select NEXTKEY ;
from tls_KeyCollection (NOLOCK);
where upper(TABLENAME) == upper(cTable) ;
into cursor C_KEY
