boolean |
checkOperandTypes(SqlCallBinding callBinding,
boolean throwOnFailure)
Checks that the operand values in a
SqlCall to this operator are
valid. |
protected RelDataType |
getComponentType(RelDataTypeFactory typeFactory,
java.util.List<RelDataType> argTypes) |
RelDataType |
inferReturnType(SqlOperatorBinding opBinding)
Infers the return type of an invocation of this operator; only called
after the number and types of operands have already been validated.
|
void |
unparse(SqlWriter writer,
SqlCall call,
int leftPrec,
int rightPrec)
Writes a SQL representation of a call to this operator to a writer,
including parentheses if the operators on either side are of greater
precedence.
