Sql - Check if stored procedure is running

In SQL Server, determining if a stored procedure is currently running can be achieved by querying the system dynamic management views (DMVs). Specifically, you can use sys.dm_exec_requests and sys.dm_exec_sql_text to find currently executing requests and their associated SQL text, which can include stored procedures.

Here's how you can check if a stored procedure is running:

Query Example

This query checks for any running instances of a stored procedure named my_stored_procedure:

SELECT r.session_id, r.start_time, r.status, r.command, DB_NAME(r.database_id) AS database_name, t.text AS sql_text FROM sys.dm_exec_requests r CROSS APPLY sys.dm_exec_sql_text(r.sql_handle) t WHERE t.text LIKE '%my_stored_procedure%';

Explanation

  • sys.dm_exec_requests: Contains information about each request currently executing in SQL Server.
  • sys.dm_exec_sql_text: Returns the text of the SQL batch that is currently executing.
  • CROSS APPLY: Used to join each row from sys.dm_exec_requests with the corresponding SQL text from sys.dm_exec_sql_text.
  • WHERE t.text LIKE '%my_stored_procedure%': Filters the results to include only those where the SQL text contains the name of your stored procedure.

Example Scenario

Suppose you have a stored procedure named usp_my_procedure. The following query will help you determine if this stored procedure is currently running:

SELECT r.session_id, r.start_time, r.status, r.command, DB_NAME(r.database_id) AS database_name, t.text AS sql_text FROM sys.dm_exec_requests r CROSS APPLY sys.dm_exec_sql_text(r.sql_handle) t WHERE t.text LIKE '%usp_my_procedure%';

Additional Filters and Information

You can refine the query further by adding additional filters or columns to retrieve more specific information. For example, you might want to filter by a specific database or exclude system sessions:

SELECT r.session_id, r.start_time, r.status, r.command, DB_NAME(r.database_id) AS database_name, t.text AS sql_text, s.login_name, s.host_name FROM sys.dm_exec_requests r JOIN sys.dm_exec_sessions s ON r.session_id = s.session_id CROSS APPLY sys.dm_exec_sql_text(r.sql_handle) t WHERE t.text LIKE '%usp_my_procedure%' AND DB_NAME(r.database_id) = 'my_database' AND s.is_user_process = 1;

Explanation of Additional Columns and Filters

  • sys.dm_exec_sessions: Contains information about user sessions. This is joined to get additional session-related details.
  • s.login_name: The login name of the user running the request.
  • s.host_name: The name of the host from which the request originated.
  • DB_NAME(r.database_id) = 'my_database': Filters the results to only include requests running in the specified database.
  • s.is_user_process = 1: Ensures that only user processes are included, excluding system sessions.

Summary

By querying the dynamic management views sys.dm_exec_requests and sys.dm_exec_sql_text, you can effectively determine if a specific stored procedure is currently running in SQL Server. Adjust the query to fit your specific needs, such as filtering by database or including additional session information.

Examples

  1. SQL check if a specific stored procedure is currently running

    Description: Determine if a specific stored procedure is actively running in SQL Server.

    -- Example: Check if a specific stored procedure is running in SQL Server DECLARE @ProcedureName NVARCHAR(128) = 'YourStoredProcedureName'; IF EXISTS ( SELECT 1 FROM sys.dm_exec_requests AS r INNER JOIN sys.dm_exec_sessions AS s ON r.session_id = s.session_id WHERE r.command LIKE 'EXEC%' AND r.status = 'running' AND OBJECT_NAME(r.objectid, r.database_id) = @ProcedureName ) BEGIN -- Stored procedure is running PRINT 'Stored procedure is running'; END ELSE BEGIN -- Stored procedure is not running PRINT 'Stored procedure is not running'; END;

  2. SQL check if any stored procedure is currently running

    Description: Determine if any stored procedure is currently executing in SQL Server.

    -- Example: Check if any stored procedure is running in SQL Server IF EXISTS ( SELECT 1 FROM sys.dm_exec_requests AS r INNER JOIN sys.dm_exec_sessions AS s ON r.session_id = s.session_id WHERE r.command LIKE 'EXEC%' AND r.status = 'running' ) BEGIN -- Any stored procedure is running PRINT 'At least one stored procedure is running'; END ELSE BEGIN -- No stored procedure is running PRINT 'No stored procedure is running'; END;

  3. SQL check if a stored procedure is running based on session ID

    Description: Check if a stored procedure is currently running based on its associated session ID in SQL Server.

    -- Example: Check if a stored procedure is running based on session ID in SQL Server DECLARE @SessionID INT = <SessionID>; IF EXISTS ( SELECT 1 FROM sys.dm_exec_requests AS r WHERE r.command LIKE 'EXEC%' AND r.status = 'running' AND r.session_id = @SessionID ) BEGIN -- Stored procedure with session ID is running PRINT 'Stored procedure with session ID is running'; END ELSE BEGIN -- No stored procedure with session ID is running PRINT 'No stored procedure with session ID is running'; END;

  4. SQL check if any long-running stored procedures

    Description: Identify any long-running stored procedures currently executing in SQL Server.

    -- Example: Check if any long-running stored procedures in SQL Server DECLARE @ThresholdSeconds INT = 60; -- Adjust threshold as needed IF EXISTS ( SELECT 1 FROM sys.dm_exec_requests AS r INNER JOIN sys.dm_exec_sessions AS s ON r.session_id = s.session_id WHERE r.command LIKE 'EXEC%' AND r.status = 'running' AND DATEDIFF(SECOND, r.start_time, GETDATE()) > @ThresholdSeconds ) BEGIN -- Long-running stored procedures found PRINT 'Long-running stored procedures found'; END ELSE BEGIN -- No long-running stored procedures found PRINT 'No long-running stored procedures found'; END;

  5. SQL check if stored procedure is running by database

    Description: Determine if a stored procedure is currently running within a specific database in SQL Server.

    -- Example: Check if stored procedure is running by database in SQL Server DECLARE @DatabaseName NVARCHAR(128) = 'YourDatabaseName'; DECLARE @ProcedureName NVARCHAR(128) = 'YourStoredProcedureName'; IF EXISTS ( SELECT 1 FROM sys.dm_exec_requests AS r INNER JOIN sys.dm_exec_sessions AS s ON r.session_id = s.session_id INNER JOIN sys.databases AS d ON r.database_id = d.database_id WHERE r.command LIKE 'EXEC%' AND r.status = 'running' AND d.name = @DatabaseName AND OBJECT_NAME(r.objectid, r.database_id) = @ProcedureName ) BEGIN -- Stored procedure is running in the database PRINT 'Stored procedure is running in the database'; END ELSE BEGIN -- Stored procedure is not running in the database PRINT 'Stored procedure is not running in the database'; END;

  6. SQL check if any stored procedure is blocked

    Description: Check if any stored procedure execution is blocked by another process in SQL Server.

    -- Example: Check if any stored procedure is blocked in SQL Server IF EXISTS ( SELECT 1 FROM sys.dm_exec_requests AS r WHERE r.command LIKE 'EXEC%' AND r.blocking_session_id IS NOT NULL ) BEGIN -- Stored procedure execution is blocked PRINT 'Stored procedure execution is blocked'; END ELSE BEGIN -- No stored procedure execution is blocked PRINT 'No stored procedure execution is blocked'; END;

  7. SQL check if stored procedure is running by user

  8. SQL check if stored procedure is running with specific parameters

    Description: Verify if a stored procedure is currently running with specific parameter values in SQL Server.

    -- Example: Check if stored procedure is running with specific parameters in SQL Server DECLARE @ProcedureName NVARCHAR(128) = 'YourStoredProcedureName'; DECLARE @Param1 INT = 123; DECLARE @Param2 NVARCHAR(50) = 'Value'; IF EXISTS ( SELECT 1 FROM sys.dm_exec_requests AS r INNER JOIN sys.dm_exec_sessions AS s ON r.session_id = s.session_id CROSS APPLY sys.dm_exec_sql_text(r.sql_handle) AS st WHERE r.command LIKE 'EXEC%' AND r.status = 'running' AND st.text LIKE '%' + @ProcedureName + '%' AND st.text LIKE '%' + CONVERT(NVARCHAR(50), @Param1) + '%' AND st.text LIKE '%' + @Param2 + '%' ) BEGIN -- Stored procedure is running with specific parameters PRINT 'Stored procedure is running with specific parameters'; END ELSE BEGIN -- Stored procedure is not running with specific parameters PRINT 'Stored procedure is not running with specific parameters'; END;
