Returns one row for each CHECK constraint in the current database. This information schema view returns information about the objects to which the current user has permissions.
To retrieve information from these views, specify the fully qualified name of INFORMATION_SCHEMA.view_name.
Name of the schema to which the constraint belongs.
Do not use INFORMATION_SCHEMA views to determine the schema of an object. The only reliable way to find the schema of a object is to query the sys.objects catalog view.
Actual text of the Transact-SQL definition statement.
SQL Server 2008 differs from SQL Server 2000 in the way it decodes and stores SQL expressions in the catalog metadata. The semantics of the decoded expression are equivalent to the original text; however, there are no syntactic guarantees. For example, white spaces are removed from the decoded expression.
