Force Row Level locking in SQLServer 2000 ?

Hi

Is it possible to force row level locking in one or more tables in
some database. We have some problems when SQL Server decides to choose
page- or table-level locking.
We are using SQL Server 2000.

Best regards

You can add a locking hint

SELECT * FROM tbl (ROWLOCK) WHERE col = 32

However, SQL Server may disregard that hint if row locks are possible
to achieve.

You may need to review you indexing strategy. For instance, in the example
above, I would not expect the hint to help if there is no index on col.
SQL Server will have to scan the entire table, so a tablock is called for.
