Temporary tables

Informix^® temporary tables are created through the CREATE TEMP TABLE DDL instruction or through a SELECT ... INTO TEMP statement. Temporary tables are automatically dropped when the SQL session ends, but they can also be dropped with the DROP TABLE command. There is no name conflict when several users create temporary tables with the same name.

Note: BDL reports create a temporary table when the rows are not sorted externally (by the source SQL statement).

Informix allows you to create indexes on temporary tables. No name conflict occurs when several users create an index on a temporary table by using the same index identifier.

SQLite supports temporary tables with the CREATE TEMP TABLE statement.
