The reordering is specified by an int array where the value of element at position i indicates to which element in a new SqlNode[] array the operand goes.

Parameters:

operator - Operator

order - Order

Method Detail

createCall

public SqlCall createCall(SqlParserPos pos,
                          SqlNode... operands)

Description copied from interface: SqlJdbcFunctionCall.MakeCall

Creates and return a SqlCall. If the MakeCall strategy object was created with a reordering specified the call will be created with the operands reordered, otherwise no change of ordering is applied

createCall in interface SqlJdbcFunctionCall.MakeCall

Overrides:

createCall in class SqlJdbcFunctionCall.SimpleMakeCall

operands - Operands

isValidArgCount

public java.lang.String isValidArgCount(SqlCallBinding binding)

Specified by:

isValidArgCount in interface SqlJdbcFunctionCall.MakeCall

Overrides:

isValidArgCount in class SqlJdbcFunctionCall.SimpleMakeCall

getArgCountMismatchMsg

private java.lang.String getArgCountMismatchMsg(int... possible)

reorder

protected SqlNode[] reorder(SqlNode[] operands)

Uses the data in order to reorder a SqlNode[] array.

Parameters:

operands - Operands
