Row-Level Locking in MSSQL 7 using ADO

greenspun.com : LUSENET : SQL Server Database Administration : One Thread

Dear Sir,

Iím having a hard time trying to make my application acquire one of those neat row-level locks that were introduced in MSSQL 7. I tried this query in visual basic 6 using ADO?

SELECT * FROM tablename WITH (UPDLOCK ROWLOCK) WHERE condition SELECT * FROM tablename WITH (HOLDLOCK ROWLOCK) WHERE condition SELECT * FROM tablename WITH (HOLDLOCK) WHERE condition

but these queries are not working if one user modifying the records other user also able to modify the same records. Please reply to my mail.

Thanks and regards, Rasheed

Rasheed,

Your sample code shows the lock on the select statement. Since select statements typically run quickly, the lock would not be in effect very long. You probably want to create transactions and have the lock for the entire transaction.

Hope this helps,

Eric
