Example: Using a Constant Expression to Specify the SPOOL Space for a Profile - Advanced SQL Engine - Teradata Database

The following request modifies the SPOOL space for the profile research_and_development to a size based on the constant expression 3,000,000 (HASHAMP()+1). The expression calculates the number of AMPs in the current system and scales the SPOOL space for the research_and_development profile to that size.

This is the original definition of profile research_and_development.

     CREATE PROFILE research_and_development AS
       DEFAULT DATABASE = it_dev,
       PASSWORD = (EXPIRE = 0),
       SPOOL = 2000000*(HASHAMP()+1);

The following MODIFY PROFILE request alters the SPOOL space allocation for this profile as follows.

     MODIFY PROFILE research_and_development AS
       DEFAULT DATABASE = it_dev,
       PASSWORD = (EXPIRE = 0),
       SPOOL = 3000000*(HASHAMP()+1);
