INFORMATION_SCHEMA.TABLES



By:

Overview
The INFORMATION_SCHEMA.TABLES view allows you to get information about all tables and views within a database. By default it will show you this information for every single table and view that is in the database.

Explanation
This view can be called from any of the databases in an instance of SQL Server and will return the results for the data within that particular database.

The columns that this view returns are as follows:

Column name Data type Description
TABLE_CATALOG nvarchar(128) Table qualifier.
TABLE_SCHEMA nvarchar(128) Name of schema that contains the table.
TABLE_NAME sysname Table name.
TABLE_TYPE varchar(10) Type of table. Can be VIEW or BASE TABLE.

Here is an example of data that was pulled from the AdventureWorks database.  This data was pulled using this query:

SELECT * FROM INFORMATION_SCHEMA.TABLES


To only show a list of tables you would use this query:

SELECT * FROM INFORMATION_SCHEMA.TABLES
WHERE
TABLE_TYPE =
'BASE TABLE'

To only show a list of only the view you would use this query:

SELECT * FROM INFORMATION_SCHEMA.TABLES
WHERE
TABLE_TYPE =
'VIEW'
