更新多个记录并插入另一个表

Question

How do you update several rows and for each one that was updated, insert a row in another table.

Pseudo example:

 update Table1 
 set CustQty = 20, set @UpdatedPk = PkRow 
 where Table1.customer_id = "A1233" 
   and Table1.CustQty  < 20 
 insert into Table2 (Table1Pk) values (@UpdatedPk)

Answer 1

Use OUTPUT clause:

UPDATE Table1 
SET CustQty = 20
OUTPUT INSERTED.PKRow INTO Table1PK
WHERE Table1.customer_id = "A1233" AND Table1.CustQty  < 20
