Question

Using a SELECT, I want to find the row ID of 3 columns (each value is unique/dissimilar and is populated by separate tables.) Only the ID is auto incremented.

I have a middle table I reference that has 3 values: ID, A, B.

• A is based on data from another table.
• B is based on data from another table.

How can I select the row ID when I only know the value of A and B, and A and B are not the same value?

Answer 1

Do you mean that columns A and B are foreign keys?

Does this work?

SELECT [ID] 
FROM tbl 
WHERE A = @a AND B = @b
