Question

How to loop update total field in procedures in SQL Server?

I have table 1. I want to create procedures to update total field automation.

Table1

Value 1  Value 2   Total

2         4
3         4
3         3
3         1
3         4

PROCEDURE:

Create PROCEDURE test1
AS

Select value1,value2,(value1*value2) as total from Table1

Answer 1

CREATE PROCEDURE up_UpdateTotals
AS
BEGIN

  UPDATE Table1 SET Total = Value1 + Value2 WHERE Total IS NULL OR Total <> (Value1 + Value2)

END

Will update totals for where it’s not set or not in sync (in case values change). Can be extended by adding parameters and such, ofcourse.

Update: Change + to * in case you need to multiply the values instead of add them together.
