[!INCLUDE[tsql-appliesto-ss2008-all-md](../../includes/tsql-appliesto-ss2008-all-md.md)]
Returns one row for each column in the current database that is used in a view definition. 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*.
|Column name|Data type|Description|
|-----------------|---------------|-----------------|
|**VIEW_CATALOG**|**nvarchar(**128**)**|View qualifier.|
|**VIEW_SCHEMA**|**nvarchar(**128**)**|Name of schema that contains the view.
**\*\* 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.|
|**VIEW_NAME**|**sysname**|View name.|
|**TABLE_CATALOG**|**nvarchar(**128**)**|Table qualifier.|
|**TABLE_SCHEMA**|**nvarchar(**128**)**|Name of schema that contains the table.
