|  | ## SQL or Operator
 | ||
|  | 
 | ||
|  | You can use the `OR` operator in the `WHERE` clause of `SELECT` statement. You use it when you want to select a record that satisfies at least one of the conditions in your `OR` statement. | ||
|  | 
 | ||
|  | Here is an example that selects all records from the Person table who are either male or who have the name “Mary”: | ||
|  | 
 | ||
|  | ```sql | ||
|  | SELECT Id, Name, DateOfBirth, Gender | ||
|  | FROM Person | ||
|  | WHERE Gender = “M” OR Name = “Mary” | ||
|  | ``` | ||
|  | 
 | ||
|  | You can combine others operators in the `WHERE` clause (use parenthesis to indicate the order of operations) like in this example: | ||
|  | 
 | ||
|  | ```sql | ||
|  | SELECT Id, Name, DateOfBirth, Gender | ||
|  | FROM Person | ||
|  | WHERE Gender = “M” AND (Name = “Peter” OR Name = “John”) | ||
|  | ``` | ||
|  | 
 | ||
|  | This example selects all records where Gender is "M" and Name is "Peter" as well as where Gender is "M" and Name is "John".  |
