Delete records from single Azure DB table that has no linking - reference to database and/or server name .. not supported Environment


Azure SQL database (migrated from SQL Server) 
Old database originally (15 years+) 
Dealing with a single table (trying to delete records) 
Using an admin user 
Using SSMS 2014 
There are some triggers on the table (disabling them yields no change in error)
Name of database is databasename in our example here
There is an azure blob storage where files are stored and are "referenced" by an app via the records in said tblImages table -- but I cannot see any hard link between the two (is that even possible?)


I can select, insert and update records in this table, but cannot delete.

Failing Script

delete from
[databasename].[dbo].[tblImages]
where companyid = 123


Error:


  Msg 40515, Level 15, State 1, Line 91 Reference to database and/or
  server name in 'Azure.dbo.tblImages' is not supported in this version
  of SQL Server.


But who said anything about "Azure.dbo.tblImages' ?!?

Things I've tried


Have tried fully qualifying the table name, and not - no change.
Have tried deleting records using the "edit top 200" feature, same error
tried disabling all triggers on the table, no change
tried script "create to new window" but nothing about linked databases/servers or other table constraints


Here's a simple test that succeeds with entirely same environment:

CREATE TABLE _tmpPersons (
    PersonID int,
    LastName varchar(255),
    FirstName varchar(255),
    Address varchar(255),
    City varchar(255) 
);

INSERT INTO _tmpPersons ( PersonID , LastName , FirstName , Address , City )
VALUES (123, 'Tore', 'Tess', '123 Main St.', 'Nowheresville');

select * from _tmpPersons;

delete from _tmpPersons where PersonId = 123;

select * from _tmpPersons;




I have already tried fully qualified [database].[schema].[table] and different combinations thereof.

It is definitely a table, and there ARE triggers, but disabling them changes nothing.

Zero results found from:

SELECT OBJECT_NAME(referencing_id), referenced_database_name
FROM sys.sql_expression_dependencies 
WHERE referenced_database_name IS NOT NULL;
Change your query from 

delete from
[databasename].[dbo].[tblImages]
where companyid = 123


to

delete from
[dbo].[tblImages]
where companyid = 123
