You can't. 

<blockquote>
 SQLite (under v3.6.19) does not support foreign key constraints
</blockquote>

, but you can use <code>triggers</code> for example
Check <a href="http://www.sqlite.org/cvstrac/wiki?p=ForeignKeyTriggers" rel="nofollow">this</a> it will help you.

If you have v 3.6.19, it already support foreign constraints with ON <code>UPDATE</code> or <code>DELETE CASCADE</code>
Read <a href="http://www.sqlite.org/foreignkeys.html" rel="nofollow">SQLite Foreign Key Support</a>

EDIT:

OR like wrote @Paul Sasik

blocks|key|1361049|text|您可以尝试使用IN子句进行子查询。类似于：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1361050|DELETE+FROM+OrderData+WHERE+OrderData.Order_ID+IN

You could try a subquery with an IN clause. Something like:

<pre><code>DELETE FROM OrderData WHERE OrderData.Order_ID IN
(SELECT OrderInfo.Order_ID 
FROM OrderInfo
JOIN CustData on OrderData.Order_ID = OrderInfo.Order_ID 
WHERE CustData.Bus_Name = 'Albertsons')
</code></pre>

to test the query before deleting just do this: (will return all rows that would be deleted by the delete query)

<pre><code>SELECT * FROM OrderData WHERE OrderData.Order_ID IN
(SELECT OrderInfo.Order_ID 
FROM OrderInfo
JOIN CustData on OrderData.Order_ID = OrderInfo.Order_ID 
WHERE CustData.Bus_Name = 'Albertsons')
</code></pre>

try 

<pre><code>DELETE FROM OrderData
WHERE OrderData.Order_ID IN (SELECT oi.Order_ID FROM OrderInfo oi 
 INNER JOIN CustData cd ON oi.Cust_id = cd.Customer_Id WHERE cd.Bus_Name='Albertsons')
</code></pre>

This is the structure of my SQLite database:
<img src="https://i.stack.imgur.com/hLigB.png" alt="enter image description here">

I am trying to delete ALL of the OrderData that belongs to a select OrderInfo.Cust_ID which belongs to a particular CustData.Cust_ID. This is my DELETE statement, which gives me the error: "no such column: CustData.Customer_ID"

<pre><code>DELETE FROM OrderData
 WHERE CustData.Customer_ID = OrderInfo.Cust_ID 
 AND OrderData.Order_ID = OrderInfo.Order_ID 
 AND CustData.Bus_Name = 'Albertsons' 
</code></pre>

I know that SQLite does NOT support JOINs in a DELETE statement, so I'm left with WHERE and ANDs; can someone please tell me the correct way to word this?

How do I create a SQL DELETE statement to delete rows in a 3rd table?
