    • gt

      public BooleanExpression gt(SQLExpression expr)
      Description copied from class: SQLExpression
      Relational operator (greater than)
      Overrides:
      gt in class NumericExpression
      Parameters:
      expr - the right-hand operand

    • add

      public SQLExpression add(SQLExpression expr)
      If both operands are instances of IntegerLiteral, the operation results in BigInteger type.
      Overrides:

      Parameters:
      expr - the right-hand operand
      Returns:
      If one of the operands is String, the returned value is the string concatenation; The sum of two operands of numeric type. The left-hand operand is the minuend and the right-hand operand is the subtrahend;
