I don’t have SQL Server CE edition, so I can’t check it, but why do you think that you need to use begin end block? Can’t you just use this code?

IF NOT EXISTS (SELECT *

FROM INFORMATION_SCHEMA.COLUMNS

WHERE TABLE_NAME = 'DELIVERYINTRIP'

AND COLUMN_NAME = 'PODID')

ALTER TABLE DELIVERYINTRIP ADD PODID UNIQUEIDENTIFIER NULL
