获取已删除的列数

Question

Here's the DELETE query:

DELETE FROM Disk
WHERE
Disk.Name = 'Recovery'

How can I get deleted column count in sql-server ?

Answer 1

Right after the statement do:

set @num_deleted = @@rowcount

@@rowcount is a system variable that has the number of rows affected by the previous statement. Read about it here .

If you want to ask more about the rows than merely the number, you can use the OUTPUT clause to put them into a table variable. You can then get the total number and other information about them.
