Question

This is my Insert Statement

INSERT INTO ProductStore (ProductID, StoreID, CreatedOn)
(SELECT DISTINCT(ProductId), 1, GETDATE() FROM ProductCategory
WHERE EXISTS (SELECT StoreID, EntityID FROM EntityStore
WHERE EntityType = 'Category' AND ProductCategory.CategoryID = EntityStore.EntityID AND StoreID = 1))

I am trying to Insert into table ProductStore, all the Products Which are mapped to Categories that are mapped to Store 1. Column StoreID can definitely have more than one row with the same entry. And I am getting the following error: Violation of Primary Key Constraint…

However, the Following query does work:

    INSERT INTO ProductStore (ProductID, StoreID, CreatedOn)
VALUES (2293,1,GETDATE()),(2294,1,GETDATE())

So apparently, the ProductID Column is trying to insert the same one more than once.

Can you see anything wrong with my query?

TIA

Answer 1

I don’t see any part of that query that excludes records already in the table.
