- 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:

-
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:

-
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

-
add
If both operands are instances of IntegerLiteral, the operation results in BigInteger type.- 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
If both operands are instances of IntegerLiteral, the operation results in BigInteger type.- 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
If both operands are instances of IntegerLiteral, the operation results in BigInteger type.- Overrides:
mul
in classNumericExpression
- Parameters:
expr
- the right-hand operator- Returns:
- The binary * operator performs multiplication, producing the product of its operands.
-
div
If both operands are instances of IntegerLiteral, the operation results in BigInteger type.- Overrides:
div
in classNumericExpression
- Parameters:
expr
- the right-hand operator- Returns:
- The binary / operator performs division, producing the quotient of its operands
-
mod
If both operands are instances of IntegerLiteral, the operation results in BigInteger type.- Overrides:
mod
in classNumericExpression
- Parameters:
expr
- The expression to modulus against- Returns:
- The modulus expression
-
neg
Negate operation. Results in BigInteger type.- 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()
