Compound Searching Using The SQL WHERE Statement With The IN Operator

One of the most important aspects of searching for objects is to be able to define multiple values in a search. We looked at searching using text globbing. But the IN operator goes a step and allows you to search
The IN operator allows you to specify multiple values in a WHERE clause.

SELECT column
FROM table
WHERE column IN (value,value,...);

In this article, we’ll use the same “Customers” table from our first articles:

ID Site Contact Address City Zip Country
1 Krypted Charles Edge my house Minneapolis 55418 US
2 Apple Tim Cook spaceship Cupertino 95014 US
3 Microsoft Satya Nadella campus Redmond 98053 US
4 Facebook Mark Zuckerberg foodhall Menlo Park 94025 US
5 JAMF Dean Hager Grain Exchange Minneapolis 55418 US

The following outputs all customers with a Site of “Krypted” or “JAMF”:

SELECT * FROM Customers
WHERE Site IN ('Krypted','JAMF');

When looking to use the IN operator, note that strings are quoted and separated by commas (,) inside parenthesis.
