Which statement about spool space is true?
-
Spool space must be specified during creation of the user
-
Spool space is used to hold the intermediate result set
-
Spool space is permanent space.
-
Spool space is limited to the size of the table.
To answer this question, the user needs to understand what spool space is and its purpose in a database system.
Option A is incorrect because spool space is not a parameter that is specified during the creation of a user; it is a system resource that is managed by the database.
Option B is correct because spool space is used to store intermediate result sets generated during query processing. Intermediate results are stored in spool space before they are written to disk or sent back to the user.
Option C is incorrect because spool space is not permanent space. It is a temporary storage area that is allocated to each user session and released when the session ends.
Option D is incorrect because spool space is not limited to the size of the table. It is a separate resource that is managed independently of the table storage.
Therefore, the correct answer is:
The Answer is: B
Spool space in Teradata is temporary working storage used to hold intermediate results while a query is being processed — for example, rows being sorted, joined, or aggregated before the final result set is produced. It isn't permanent storage, and while a spool limit is assigned per user, it isn't fixed to any single table's size.
