[New Issue] What is the difference between SCOPE_IDENTITY() being written before and after in t-sql?

  1. select SCOPE_IDENTITY() insert into tb_GoodsInfo values('sd','电器','232131','7','222')
  2. go
  3. insert into tb_GoodsInfo values('sd','电器','232131','7','222') select SCOPE_IDENTITY()
  4. go
Copy code
If the normal ID is 1, then the SQL statement on the first line will return null.
The SQL statement on the second line will return 1,

What is the difference between writing SCOPE_IDENTITY () before and after ()? Why is there such a big effect?




Previous:sql gets the primary key value after waiting for INSERT
Next:asp.net simple three-layer architecture (purchase, sales and inventory management system) project source code
