Checks that the operand values in a
SqlCall to this operator are
valid. |

getAllowedSignatures(java.lang.String opName)
Returns a string describing the expected operand types of a call, e.g.
|
SqlOperandCountRange |
getOperandCountRange()
Returns a constraint on the number of operands expected by this operator.
|
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.
