  • What is Object_id in MS SQL

    Hello everybody,

    today I want to leave a short notice on OBJECT_ID in MS SQL.

    Quite often I've seen sql like this:

    IF OBJECT_ID(N'dbo.Students', N'U') IS NOT NULL DROP TABLE dbo.Students;

    Today I have found time to discover what it actually means.
