no more spool space in Database

Spool space problems occur either when you have an inefficient query or when statistics have not been properly collected on the tables you are using. It can also happen with tables where the primary index was poorly chosen (high skew). Spool is an attribute of the user account you are using to connect to the Teradata environment; it is not really an attribute of the database itself.

The only way to know for certain is to look at the EXPLAIN plan for your query.

If your query is inefficient, rewrite it. If statistics need to be collected or if the index needs to be altered, contact the DBA responsible for the tables you are using.

If there is a particular query that is giving you an "out of spool" error, update this question with the complete text of the query.

I was not able to resolve my "out of spool" error by the methods above. I resolved the error by moving a rank function into its own small table without any join or extraneous columns.

Spool space can occur when you use tables having large data. If you are using multiple tables, check if you are using alias names instead of referring the complete table. Using alias names actually narrows down the data by the joins. Also see if functions like oreplace which consume more data are being used. Try using regular expressions in that case.
