Method Details
-
eq
Description copied from class:SQLExpression
Equality operator (equals to)- Overrides:
eq
in classNumericExpression
- Parameters:
expr
- the right-hand operand- Returns:
- The type of an equality expression is a boolean
-
ne
Description copied from class:SQLExpression
Not equality operator (not equals to)- Overrides:
ne
in classNumericExpression
- Parameters:
expr
- the right-hand operand- Returns:
- The type of an equality expression is a boolean
-
lt
Description copied from class:SQLExpression
Relational operator (lower than)- Overrides:
lt
in classNumericExpression
- 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
Description copied from class:SQLExpression
Relational operator (lower than or equals)- Overrides:
le
in classNumericExpression
- 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
Description copied from class:SQLExpression
Relational operator (greater than)- Overrides:
gt
in classNumericExpression
- 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
Description copied from class:SQLExpression
Relational operator (greater than or equals)- Overrides:
ge
in classNumericExpression
- 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
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 classNumericExpression
- 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
Description copied from class:SQLExpression
Additive Operator. The binary - operator subtracts right-hand operand from left-hand operand.- Overrides:
sub
in classNumericExpression
- 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.
-
mul
Description copied from class:SQLExpression
Multiplication Operator- Overrides:
mul
in classNumericExpression
- Parameters:
expr
- the right-hand operator- Returns:
- The binary * operator performs multiplication, producing the product of its operands.
-
div
Description copied from class:SQLExpression
Division Operator. The left-hand operand is the dividend and the right-hand operand is the divisor.- Overrides:
div
in classNumericExpression
- Parameters:
expr
- the right-hand operator- Returns:
- The binary / operator performs division, producing the quotient of its operands
-
neg
Description copied from class:SQLExpression
Unary Minus Operator- Overrides:
neg
in classNumericExpression
- Returns:
- the type of the unary minus expression is the promoted type of the operand.
-
getValue
Description copied from interface:SQLLiteral
Accessor to the literal value- Specified by:
getValue
in interfaceSQLLiteral
- Returns:
- the value of the literal
-
setNotParameter
public void setNotParameter()Description copied from interface:SQLLiteral
Method to set this literal as not being a parameter. If the literal if not currently a parameter then does nothing. Updates any underlying SQL to have the value.- Specified by:
setNotParameter
in interfaceSQLLiteral
-
setStatement
protected void setStatement()
-
