Returns one row for each alias data type in the current database that has a rule bound to it and that can be accessed by current user.
To retrieve information from these views, specify the fully qualified name of **INFORMATION_SCHEMA.**view_name.
| Column name | Data type | Description |
|---|---|---|
| CONSTRAINT_CATALOG | nvarchar(128) | Database in which the rule exists. |
| CONSTRAINT_SCHEMA | nvarchar(128) | Name of schema that contains the constraint. ** Important ** 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. |
| CONSTRAINT_NAME | sysname | Rule name. |
| DOMAIN_CATALOG | nvarchar(128) | Database in which the alias data type exists. |
| DOMAIN_SCHEMA | nvarchar(128) | Name of schema that contains the alias data type. ** Important ** Do not use INFORMATION_SCHEMA views to determine the schema of a data type. The only reliable way to find the schema of a type is to use the TYPEPROPERTY function. |
| DOMAIN_NAME | sysname | Alias data type. |
| IS_DEFERRABLE | varchar(2) | Specifies whether constraint checking is deferrable. Always returns NO. |
| INITIALLY_DEFERRED | varchar(2) | Specifies whether constraint checking is at first deferred. Always returns NO. |
