Package org.apache.druid.sql.calcite.planner

Class RelParameterizerShuttle

java.lang.Object
org.apache.druid.sql.calcite.planner.RelParameterizerShuttle
All Implemented Interfaces:
org.apache.calcite.rel.RelShuttle
public class RelParameterizerShuttle extends Object implements org.apache.calcite.rel.RelShuttle
Traverse RelNode tree and replaces all RexDynamicParam with RexLiteral using RexBuilder if a value binding exists for the parameter. All parameters must have a value by the time RelParameterizerShuttle is run, or else it will throw an exception. Note: none of the tests currently hit this anymore since SqlParameterizerShuttle has been modified to handle most common jdbc types, but leaving this here provides a safety net to try again to convert parameters to literal values in case SqlParameterizerShuttle fails.
