The AND operation is the result of the multiplication of both binary values. For example, let's assume that @a is a variable and we want to increase the value of @ a by 2. (Just like when you were learning the order of operations in Math class!) Comparison operators. For example, suppose that the value of @a is initially 9. That is, if one of the two corresponding values are 1, the result will be 1. Examples The following examples demonstrate compound operations. Compound-assignment operators provide a shorter syntax for assigning the result of an arithmetic or bitwise operator. As a result of @a%=4, the value of @a will be 1. The following table shows the operand types of compound assignment expressions: However, in a compound expression, some combinations of functions are inappropriate and are rejected. . Queries containing set operators are called compound queries. %. Operators are the foundation of any programming language.
