通过T-SQL检索受影响的记录

Question

以下示例返回受影响的ROWCOUNT。有没有办法返回受影响的IDENTITY？

UPDATE HumanResources.Employee 
SET JobTitle = N'Executive'
WHERE NationalIDNumber = 123456789
IF @@ROWCOUNT = 0
PRINT 'Warning: No rows were updated';

Answer 1

UPDATE HumanResources.Employee 
SET JobTitle = N'Executive'
OUTPUT INSERTED.YourIdentityColumn
WHERE NationalIDNumber = 123456789

OUTPUT

Answer 2

UPDATE HumanResources.Employee 
SET JobTitle = N'Executive'
OUTPUT INSERTED.PrimaryKeyID
WHERE NationalIDNumber = 123456789

这里我假设Id名称是PrimaryKeyID。

Answer 3

从这里https://msdn.microsoft.com/ru-ru/library/ms177564(v=sql.120).aspx

DELETE FROM dbo.table1
OUTPUT DELETED.* INTO @MyTableVar
WHERE id = 4 OR id = 2;
