There are several ways to check if a table is locked in SQL Server.

  1. a command used to view information about locks on objects in a SQL Server database
EXEC sp_lock
  1. the dynamic management view for locks in the system
SELECT * FROM sys.dm_tran_locks
  1. Using Activity Monitor: You can use the Activity Monitor in SQL Server Management Studio (SSMS) to view the queries and locking information that are currently being executed. Simply open SSMS, select the database you want to monitor, and go to the “Activity Monitor” tab where you can see the tables and queries currently being locked.
  2. By using query statements, lock information can be retrieved by querying system tables sys.syslockinfo and sys.sysprocesses. Here is an example query:
SELECT *
FROM sys.syslockinfo AS l
INNER JOIN sys.sysprocesses AS p ON l.req_spid = p.spid

These are some commonly used methods for checking if a table is locked in SQL Server. Choose an appropriate way to view based on your needs.
