request_id The request_id from sys.dm_exec_requests. request_id is int.
Table Returned
| Column name | Data type | Description |
|---|---|---|
| event_type | nvarchar(256) | The type of event in the input buffer for the given spid. |

Permissions
On SQL Server, if the user has VIEW SERVER STATE permission, the user will see all executing sessions on the instance of SQL Server; otherwise, the user will see only the current session.
Important
Running this DMV outside of SQL Server Management Studio against SQL Server without VIEW SERVER STATE permissions (such as in a trigger, stored procedure, or function) throws a permission error on the master database.
On SQL Database, if the user is the database owner, the user will see all executing sessions on the SQL Database; otherwise, the user will see only the current session.
Important
Running this DMV outside of SQL Server Management Studio against Azure SQL Database without owner permissions (such as in a trigger, stored procedure, or function) throws a permission error on the master database.
Remarks
This dynamic management function can be used in conjunction with sys.dm_exec_sessions or sys.dm_exec_requests by doing CROSS APPLY.
Examples
A. Simple example
The following example demonstrates passing a session ID (SPID) and a request ID to the function.
SELECT * FROM sys.dm_exec_input_buffer (52, 0);
GO
B. Using cross apply to additional information
The following example lists the input buffer for user sessions.
SELECT es.session_id, ib.event_info
FROM sys.dm_exec_sessions AS es
CROSS APPLY sys.dm_exec_input_buffer(es.session_id, NULL) AS ib
WHERE es.is_user_process = 1;
GO
