Constructor Detail

FarragoRexBuilder

public FarragoRexBuilder(FarragoPreparingStmt preparingStmt)

Method Detail

makeLiteral

public RexLiteral makeLiteral(String s)

Description copied from class: RexBuilder

Creates a character string literal.

Overrides:

makeLiteral in class RexBuilder

getPreparingStmt

public FarragoPreparingStmt getPreparingStmt()

makeCall

public RexNode makeCall(SqlOperator op,
                        RexNode... exprs)

Description copied from class: RexBuilder

Creates a call with an array of arguments.

This is the fundamental method called by all of the other makeCall methods. If you derive a class from RexBuilder, this is the only method you need to override.

Overrides:

makeCall in class RexBuilder

makeUdfInvocation

private RexNode makeUdfInvocation(SqlOperator op,
                                  RexNode[] exprs)

makeComparison

private RexNode makeComparison(SqlOperator op,
                               RexNode[] exprs)

makeRelativeComparison

private RexNode makeRelativeComparison(FemUserDefinedType udt,
                                       FemUserDefinedOrdering udo,
                                       SqlOperator op,
                                       RexNode[] exprs)

makeMapComparison

private RexNode makeMapComparison(FemUserDefinedType udt,
                                  FemUserDefinedOrdering udo,
                                  SqlOperator op,
                                  RexNode[] exprs)

getRoutine
