How to Detect and Resolve Row-Level Locks in SQL Server 2005

While it may not be possible to pinpoint the exact rows locked by a specific query batch, there are methods to gain insight into table row-level locking.

Finding Blocked Statements

Running the following query displays a list of currently blocked statements:

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

This query reveals which statements are blocked and provides information on the blocking objects. By tracing this information back, you can identify the statement that initiated the initial block.

Additional Assistant

@MikeBlandford's comment offers an additional tip:

• The "blocked" column identifies the process ID (SPID) of the blocking process.
• To resolve the issue, you can execute kill {SPID} to terminate the blocking process.

Note:

It's important to emphasize that these methods do not show the specific locked rows. However, they can guide you towards identifying the cause of blocking and resolving the issue.
