sql - Default value with two sets of parentheses instead of one -
let's have int field, , set default value (0), works, i've seen people doing instead ((0)),why?
((0)) how appear within catalog views or if generate script in ssms. think when see it's generated script , not hand-written way scratch.
that said, there nothing different between (0), ((0)) or (((((((((((((0))))))))))))) ... assuming counted right, parentheses don't change meaning, readability.
