Comparison operators in Salesforce are very useful to fetch the data in Salesforce Database using SOQL. They are used to compare the data with the values we provide. By using these operators we can customize the data we wanted to fetch from the database. Application of these operators at suitable positions in the queries retrieves the exact data needed. Hence let’s quickly see some of the important Operators in the below table.

| = | Equals | Equals operator fetches the data only which is equal to the values provided. | SELECT Name FROM Account WHERE Name = ‘Amazon’ |
| != | Not equals | Not equals operator fetches the data apart from the value provided. | SELECT Name FROM Account WHERE Name != ‘Amazon’ |
| < | Less than | Less than operator fetches the data whose fields value is less than the provided value. | SELECT Name FROM Account WHERE NumberOfEmployees < 10 |
