RDBMS In-Database Processor
Overview
The RDBMS In-Database Processor tool executes a series of SQL statements on a series of records, with each statement obtained from an input field. The tool executes each statement in succession. No result set is returned from the SQL statements, and no processing is performed on the SQL statements. The statements are executed exactly as presented to the tool.
This can provide significant performance improvements over traditional approaches, which require that data be moved out of the database for processing and then pushed back to the database server.
