 | |
| ## 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".
