Abstract
Techniques are provided for executing query statements, or portions thereof, in parallel without using slave SQL to communicate to each slave the operations to be performed by the slave. Instead of generating one cursor for the query coordinator (QC) based on the original statement, and separate cursors for each DFO based on the slave SQL, the techniques involve sharing the cursor that is generated from the original statement among the various participants involved in the parallel execution of the operations specified in the original statement.
