SQL commands
For all databases query sys.sysprocesses to find open transactions. It is useful to find locks in DB:
SELECT * FROM sys.sysprocesses WHERE open_tran = 1
For the current database use:
DBCC OPENTRAN
To find row counts for all tables. Very useful when we don’t know where to start when working in a new DB.
