How to add multiple columns to a table and add default constraint on one of them?

Question

I want to add 2 new columns to existing table.

One of them should be NOT NULL with default value 0 (filled in the existing rows as well).

I have tried the following syntax:

Alter TABLE dbo.MamConfiguration     add [IsLimitedByNumOfUsers] [bit]  NOT NULL,     CONSTRAINT IsLimitedByNumOfUsers_Defualt [IsLimitedByNumOfUsers] DEFAULT 0     [NumOfUsersLimit] [int] NULL go 

But it throws exception. How should I write it?

Answer 1

You can use this:

ALTER TABLE dbo.MamConfiguration ADD [IsLimitedByNumOfUsers] [BIT] NOT NULL DEFAULT 0,        [NumOfUsersLimit] [INT] NULL GO 

or this:

ALTER TABLE dbo.MamConfiguration ADD [IsLimitedByNumOfUsers] [BIT] NOT NULL          CONSTRAINT IsLimitedByNumOfUsers_Default DEFAULT 0,     [NumOfUsersLimit] [INT] NULL go
