sql-server-2005

问题 Is there a good way to tell who created a stored procedure in SQL Server 2005 (that also works in 2008)? In SQL Management Studio I can right mouse/properties on a proc to get the created date/time but how do I discover the creator? 回答1: It may be too late for you now, but you can keep track of DDL activity.

问题 How can we check that table have index or not ? if have how to find that index for a particular column for a table? Regards, kumar 回答1: In SQL Server Management Studio you can navigate down the tree to the table you're interested in and open the indexes node. Double clicking any index in that node will then open the properties dialog which will show which columns are included in the index. If you would like to use T-SQL, this might help: SELECT sys.tables.name, sys.indexes.name, sys.columns
