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”:
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:
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".
