    • not

      public SqlOperator not()
      Description copied from class: SqlOperator
      Returns the operator that is the logical inverse of this operator.

      For example, SqlStdOperatorTable.LIKE.not() returns SqlStdOperatorTable.NOT_LIKE, and vice versa.

      By default, returns null, which means there is no inverse operator.

      public SqlOperandCountRange getOperandCountRange()
      Description copied from class: SqlOperator
      Returns a constraint on the number of operands expected by this operator. Subclasses may override this method; when they don't, the range is derived from the SqlOperandTypeChecker associated with this operator.

      public boolean checkOperandTypes(SqlCallBinding callBinding, boolean throwOnFailure)
      Description copied from class: SqlOperator
      Checks that the operand values in a SqlCall to this operator are valid. Subclasses must either override this method or supply an instance of SqlOperandTypeChecker to the constructor.

      The default implementation of this method delegates to SqlSyntax.unparse(org.apache.calcite.sql.SqlWriter, org.apache.calcite.sql.SqlOperator, org.apache.calcite.sql.SqlCall, int, int).
