Question

I am running a query that returns records from the LEFT of the EXCEPT that are not on the right query;

USE AdventureWorks;
GO
SELECT ProductID 
FROM Production.Product
EXCEPT
SELECT ProductID 
FROM Production.WorkOrder;

Lets say there are 6 records returned (there are 6 records in Production.Product table, that are not in Production.WorkOrder)

How would I write the query to update the 6 records into Production.WorkOrder table?

Answer 1

insert into workorder (productid)
select productid from product where productid not in (select productid from workorder)

This will insert into workorder all the productid’s in the product table that aren’t already in workorder.
