Abstract
Presented is a system and method for evaluating relational database queries in a distributed system. An optimized query plan is received by a control node. The query plan is decoded to a SQL statement that is semantically equivalent to the query plan, even though the query plan contains elements that have no direct analog in SQL. The decoded SQL is transmitted to a compute node for execution.
