How Can I Check for Table-Level Locks in SQL Server 2005 in Real Time?

Investigating Table-Level Locking in SQL Server 2005

One of the challenges faced by database administrators is determining which locks are held on specific tables. This information is crucial for troubleshooting blocking issues and ensuring optimal database performance.

Can we check table-level locks against a query batch in real time?

Determining which locks are applied to rows for a specific query batch can provide valuable insights into blocking scenarios. However, it's important to note that SQL Server 2005 does not provide a direct mechanism to determine row-level locking in real time.

Identifying Blocked Statements

While it's not possible to pinpoint exact row-level locking, we can identify statements that are experiencing blocking using the following query:

select cmd, * from sys.sysprocesses where blocked > 0

This query displays the processes that are blocked and provides information about the blocking entity. By tracing the blocking hierarchy, we can determine the root cause of the blocking situation.

Additional Note from @MikeBlandford

The blocked column indicates the session ID (SPID) of the blocking process. To resolve the issue, one can run kill {SPID} to terminate the blocking session.
