Which lock hints should I use (T-SQL)?

Question

I want to implement an atomic transaction like the following:

BEGIN TRAN A

SELECT id
FROM Inventory
WITH (???)
WHERE material_id = 25 AND quantity > 10

         


        

Answer 1

MSSQL:

SELECT id
FROM Inventory (UPDLOCK)
WHERE material_id = 25 AND quantity > 10;

By any chance you're interested with PostgreSQL:

SELECT id
FROM Inventory    
WHERE material_id = 25 AND quantity > 10
FOR UPDATE;
