    • lt

      public BooleanExpression lt(SQLExpression expr)
      Description copied from class: SQLExpression
      Relational operator (lower than)
      Overrides:
      lt in class CharacterExpression
      Parameters:
      expr - the right-hand operand
      Returns:
      true if the value of the left-hand operand is less than the value of the right-hand operand, and otherwise is false.

    • le

      public BooleanExpression le(SQLExpression expr)
      Description copied from class: SQLExpression
      Relational operator (lower than or equals)
      Overrides:
      le in class CharacterExpression
      Parameters:
      expr - the right-hand operand
      Returns:
      true if the value of the left-hand operand is less than or equal to the value of the right-hand operand, and otherwise is false.

    • gt

      public BooleanExpression gt(SQLExpression expr)
      Description copied from class: SQLExpression
      Relational operator (greater than)
      Overrides:
      gt in class CharacterExpression
      Parameters:
      expr - the right-hand operand
      Returns:
      true if the value of the left-hand operand is greater than the value of the right-hand operand, and otherwise is false.

    • ge

      public BooleanExpression ge(SQLExpression expr)
      Description copied from class: SQLExpression
      Relational operator (greater than or equals)
      Overrides:
      ge in class CharacterExpression
      Parameters:
      expr - the right-hand operand
      Returns:
      true if the value of the left-hand operand is greater than or equal the value of the right-hand operand, and otherwise is false.

    • add

      public SQLExpression add(SQLExpression expr)
      Description copied from class: SQLExpression
      Additive Operator. The binary + operator performs addition when applied to two operands of numeric type, producing the sum of the operands. If the type of either operand of a + operator is String, then the operation is string concatenation.
      Overrides:
      add in class CharacterExpression
      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;

    • sub

      public SQLExpression sub(SQLExpression expr)
      Description copied from class: SQLExpression
      Additive Operator. The binary - operator subtracts right-hand operand from left-hand operand.
      Overrides:
      sub in class CharacterExpression
      Parameters:
      expr - the right-hand operand
      Returns:
      The binary - operator performs subtraction when applied to two operands of numeric type producing the difference of its operands; the left-hand operand is the minuend and the right-hand operand is the subtrahend.

    • mod
