Is there such a thing as a task where you would not need a cursor?
Hidden in the depths of the Master database are a series of stored procedures
that can replace some cursors with these one-liners.
Traditionally if you wanted to run a DBCC CHECKTABLE on every table in a database
you’d have to write an elaborate cursor like below :
|
DECLARE @dataname varchar(255), @dataname_header varchar(255) DECLARE datanames_cursor CURSOR FOR SELECT name FROM master..sysdatabases |
Beginning with version 6.5 of SQL Server, Microsoft provides a stored procedure called
sp_MSreachfortable. Using the question mark as a place holder for all table names, the procedure
will do the same as the above query in a single line.
You can replace the above cursor with this :
|
sp_MSforeachtable @command1="print ‘?’ dbcc checktable (‘?’)" |
You can issue up to three commands to the stored procedure using @command1 through @command3.
