SQL Operators are special Words or Characters used to perform specific tasks both mathematical and logical computations on operands, which use ‘WHERE’ clause in a SQL query / statement.
There are six types of SQL operators that we are going to
cover: Arithmetic, Bitwise, Comparison, Compound, Logical and String.
Every database administrator and user uses SQL queries for
manipulating and accessing the data of database tables and views with the
help of reserved words and characters, which are used to perform arithmetic
operations, logical operations, comparison operations, compound operations, etc.
SQL Operators |
Description |
Arithmetic |
Add (+), Subtract (-), Multiply (*), Divide (/), Modulo (%) |
Bitwise |
AND (&), OR (|), exclusive OR (^) |
Comparison |
Equal to (=), Greater than (>), Less than (<), Greater than or
equal to (>=), Less than or equal to (<=), Not equal to (<>) |
Compound |
Add equals (+=), Subtract equals (-=), Multiply equals (*=), Divide
equals (/=), Modulo equals (%=), Bitwise AND equals (&=), Bitwise
exclusive equals (^-=), Bitwise OR equals (|*=) |
Few Examples:
b) ‘LIKE”
Operator: The LIKE operator
searches for a specified pattern in a column.
This operator is used in the WHERE clause with the following three
statements:
- SELECT
statement
- UPDATE
statement
- DELETE
statement
c) NOT LIKE” Operator:
d) ‘IN’ Operator: in SQL allows database users to specify two or more values in a WHERE clause. This logical operator minimizes the requirement of multiple OR conditions.
