On SQL Server requires one of the following:
- User must be a member of the sysadmin fixed server role.
- User must have VIEW SERVER STATE permission.
- session_id must be the same as the session ID on which the command is being run. To determine the session ID execute the following query:
On SQL Database Premium Tiers requires the VIEW DATABASE STATE permission in the database. On SQL Database Standard and Basic Tiers requires the SQL Database admin account.
The following example runs
DBCC INPUTBUFFER on a second connection while a long transaction is running on a previous connection.
CREATE TABLE dbo.T1 (Col1 int, Col2 char(3)); GO DECLARE @i int = 0; BEGIN TRAN SET @i = 0; WHILE (@i < 100000) BEGIN INSERT INTO dbo.T1 VALUES (@i, CAST(@i AS char(3))); SET @i += 1; END; COMMIT TRAN; --Start new connection #2. DBCC INPUTBUFFER (52);
