How do I lock a record in SQL Server?
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?
tia
function GetNextKey
lparameter cTable
local nRetVal
nRetVal = 0
select NEXTKEY ;
from tls_KeyCollection ;
where upper(TABLENAME) == upper(cTable) ;
into cursor C_KEY
if _tally = 1
update tls_KeyCollection ;
set NEXTKEY = C_KEY.NEXTKEY + 1 ;
where upper(TABLENAME) == upper(cTable)
nRetVal = C_KEY.NEXTKEY
endif
use in C_KEY
return nRetVal
Next
