In Marketing Cloud's Automation Studio, we keep getting an error for SQL we wrote that is supposed to combine the data from 2 separate SHARED data extensions in a child Business Unit. The error message that's prompted is the following

"An error occurred while checking the query syntax. Errors: The multi-part identifier "ent.France_Master_Permission.Federation_Id" could not be bound."

Below's the whole query:

SELECT ent.Country-1_Master_Contacts.TVCM_ID, 
FROM ent.Country-1_Master_Contacts
INNER JOIN ent.Country-1_Master_Permission
ON ent.Country-1_Master_Permission.Federation_Id 
= ent.Country-1_Master_Contacts.Contact_Key 
AND ent.Country-1_Master_Contacts.TVCM_ID 
= ent.Country-1_Master_Permission.TVCM_ID
WHERE Do_Not_Market_To = 'False' 
AND Unsubscribe_All = 'False' 
AND Email = 'False'

I think you need to use aliases. Change the query to the following:

SELECT mc.TVCM_ID, mc.Contact_Key, mc.Email_Address, mc.First_Name, mc.Last_Name, mc.BU_Code
    FROM ent.Country-1_Master_Contacts mc INNER JOIN ent.Country-1_Master_Permission mp
        ON mp.Federation_Id = mc.Contact_Key 
        AND mp.TVCM_ID = mc.TVCM_ID
    WHERE mp.Do_Not_Market_To = 'False' 
    AND mp.Unsubscribe_All = 'False' 
    AND mp.Email = 'False'

It also makes it a lot cleaner and more readable.

I assumed that the attributes in the where clause are from the Master_Permission Data Extension. As long as the attributes are unique over the two data extensions; there is no need to specify the alias. But I like to do it for consistency.


I don't see the field "ent.France_Master_Permission.Federation_Id" in your query. Did you update your SQL ?

When I copy/paste your current SQL in a Query Activity, I have a syntax error. The use of SQL aliases resolves this issue.

I advice you to have a quick look on this page : SQL Reference

  • Yes, it were aliases in the end. Tnx to both you guys.
