Patent abstract
A pre-pass and direct call mechanism which replaces the interpreter. The mechanism moves static decisions out of the repeated runtime path into a pre-pass operation. Advantageously, the mechanism reduces runtime overhead and improves overall performance of the DBMS during runtime, while maintaining the considerable investment in opcode generation and plan representation.
