Hinweise
The WITH NOCHECK clause of the Transact-SQL ALTER TABLE statement disables existing value check when adding a constraint to a table containing data, optimizing constraint implementation. When using SQL Distributed Management Objects (SQL-DMO) to create constraints on existing tables, use DoAlterWithNoCheck to force WITH NOCHECK behavior and optimize constraint implementation.
