How do I delete LEFT JOIN rows that are NULL in mySQL?

 How do I delete LEFT JOIN rows that are NULL in mySQL?

If by "delete" you mean "don't show them in this query result" you can use an INNER JOIN instead of a LEFT JOIN. It's worth learning the different types of joins and how to use them.

If by "delete" you mean "DELETE the rows in my_order_delivery_address that have no matching my_order", you can do a multi-table DELETE:

DELETE a FROM mt_order_delivery_address AS a
LEFT JOIN mt_order AS o USING (order_id)
WHERE o.order_id IS NULL;

 

 

Modifying the "Path to executable" of a windows service

 

 

There is also this approach seen on SuperUser which uses the sc command line instead of modifying the registry:

sc config <service name> binPath= <binary path>

Note: the space after binPath= is important. You can also query the current configuration using:

sc qc <service name>

This displays output similar to:

[SC] QueryServiceConfig SUCCESS
