What are the Operators?

Every database admin or the geeks working on databases uses SQL queries to manipulate the data and retrieve the tables’ results. This manipulation of data is performed with the help of operators. An operator is a keyword used in SQL queries to manipulate the data, and it returns the results based on the functionality of that operator.

These operators allow us to perform multiple functionalities like performing arithmetic operations, comparing two expressions, etc. It generally also acts as a conjunction between multiple conditions in a query. The operators can either be unary operators or binary operators.

Unary operators use only one operand for their execution, whereas Binary operators use two operands. Operands are nothing but the objects on which we can use the operators. For example, consider the following statement: 1 + 2. Here 1 and 2 are the operands, whereas + is the operator. In SQL, instead of using only the numbers, we generally use tables to obtain the results.
