C# comparison operators check the order of values. The operators `>`, `<`, `>=`, `<=` compare the order of values. They determine if a value is greater than or less than another value.
When SET ANSI_NULLS is ON, an operator that has one or two NULL expressions returns UNKNOWN. When SET ANSI_NULLS is OFF, the same rules apply, except for the equals (=) and not equals (<>) operators. When SET ANSI_NULLS is OFF, these operators treat NULL as a known value, equivale...
The containment operators (-contains, -notcontains, -in, and -notin) are similar to the equality operators, except that they always return a Boolean value, even when the input is a collection. These operators stop comparing as soon as they detect the first match, whereas the equality operato...
The= Operatoris also used as an assignment operator. TheIsoperator, theIsNotoperator, and theLikeoperator have specific comparison functionalities that differ from the operators in the preceding table. Comparing Numbers When you compare an expression of typeSingleto one of typeDouble, theSingleexpress...
The result of a comparison operator has theBooleandata type. This has three values: TRUE, FALSE, and UNKNOWN. Expressions that return aBooleandata type are known as Boolean expressions. Unlike other SQL Server data types, aBooleandata type cannot be specified as the data type of a table colu...

Where built-in operators return bool, most user-defined overloads also return bool so that the user-defined operators can be used in the same manner as the built-ins. However, in a user-defined operator overload, any type can be used as return type (including void). U can be any ...
Even though our proposal follows the sequential covering technique, a well-known one to render rules, it is still a novel approach. That is, we have introduced new fitness functions and genetic operators, a local search strategy to refine the found solutions. As a result of the contributions ...
Combining Operators in Awk We can also combine multiple comparison operators to create more complex conditions. For example, if we want to filter out food items whose quantity is between 20 and 50, we can use the logical AND operator(&&)as shown. ...
