i had the same issue, had to take it out of the begin end due to it expecting external

so i ended up doing this

IF EXISTS (SELECT name FROM sys.schemas WHERE name = N'DB')

BEGIN

PRINT 'Dropping the DB schema'

DROP SCHEMA [DB]

END

GO

PRINT ' Creating the DB schema'

GO

CREATE SCHEMA [DB] AUTHORIZATION [dbo]

GO

CREATE SCHEMA must be in its own batch. What that means in context of your script if you will need to execute your create schema via dynamic sql.

Here is what Sean meant (using Anthony's sample code):

IF NOT EXISTS ( SELECT *

FROM sys.schemas

WHERE name = N'DB' )

EXEC('CREATE SCHEMA [DB] AUTHORIZATION [dbo]');

GO

Thanks Guys,I had suspected it needed to be in its own batch after a little playing around.

If you post your original sql into a ssms window the create schema will be red squiggly. On mouse over it will tell you exactly that. 😉
