How to view table space usage in Teradata.

To check the table space usage of a Teradata database, you can follow these methods:

1. By utilizing the DBC.TablesV view, running the following SQL query can gather information on the space usage of each table.
2. Retrieve the current and maximum permitted space usage for all tables in the database sorted by database name and table name.
3. This will return the database name, table name, current permanent space usage, and maximum permanent space limit for each table.
4. Use the DBC.AllSpaceV view: Running the following SQL query can retrieve information on the space usage of each database.
5. Retrieve the total current and maximum permissions used for each database from the DBC.AllSpaceV table.
6. This will return the name of each database, the total permanent space used, and the total maximum permanent space for each one.
7. Utilizing Teradata management tools such as Teradata Viewpoint or Teradata Administrator allows for a graphical interface to easily monitor tablespace usage, including information on space usage for each database and table, as well as remaining space.

Please note that the above methods require appropriate access permissions to run queries or use management tools to view tablespace usage.
