Question

Using SQL server is it possible to to a mass insert based on a sub query, Essentially I’m trying to do this.

Insert into ProductExtra (ProductID,ExtraID) 
VALUES 
(Select ProductID From ProductSKU 
JOIN Product on ProductSKU.ProductID = Product.ID
Where ItemType = 'fire grate' ), 10739

Answer 1

Yes – but then you must not use the VALUES keyword, but this syntax (just a SELECT, with columns and fixed values defined in its list of selected columns) instead:

INSERT INTO ProductExtra (ProductID, ExtraID) 
   SELECT ProductID, 10739
   FROM ProductSKU 
   JOIN Product ON ProductSKU.ProductID = Product.ID
   WHERE ItemType = 'fire grate'
