The amount of data, and the number and types of indexes you create, determine how much space you need in your database.
If you run out of space when loading or inserting into a database, the server rolls back either the entire transaction or rolls back to a savepoint.
In addition to any temporary tables you explicitly define, SAP Sybase IQ uses the temporary store as a temporary result space for sorts, hashes, and bitmaps during loads and deletions. The types of queries issued, the degree of concurrent use, and the size of your data all determine how much space you need for your temporary store.
