>>Hi,
>>I would like to create a SQL Server command that would set a column to a value and at the same time set the value before the change.
>>
>>For example, say I have a table PartTable and I want to update the value of column INSTOCK to some value of the variable @StockQty but first set the value of this column to another variable, @StockQtyBeforeChange. This is the UPDATE part of the desired statement:

>>
>>update PartTable set instock = @StockQty where inv_code = @InvCode
>>
>>
>>but I cannot see how to add the following into the statement above:
>>
>>
>>select @StockQtyBeforeChange = instock from PartTable where inv_code = @InvCode

>>Is it possible to do what I am thinking? TIA

>Look into OUTPUT clause for UPDATE command in order to set variables of before and after values (Deleted and Inserted tables).
