Help with SQL query in Alert

I'm inserting information into an email alert via a SQL query. I have the query referencing 2 tables and inner joining them. The query works fine, but placed inside an alert it doesn't work right.

 for example:

select Last_Name, First_Name, Company, Job_Title, Business_Phone, Moblie_Phone

from Contacts innerjoin Nodes on Contacts.Company = Nodes.Coop

where Caption ='Name_of_Node'
