use testdb1
go
UPDATE dbo.testdb
SET testcol1 = 'test'
WHERE (dbo.testdb.testcolx = testdb2.dbo.testdb.testcolx)

I have tried rearranging this code as much as possible and have encountered the same error:

"The column prefix testdb2.dbo.testdb' does not match with a table name or alias name used in the query.""

You need a FROM clause here. Try something like this:

UPDATE dbo.testdb
SET testcol1 = 'test'
FROM dbo.testdb
JOIN testdb2.dbo.testdb t2 ON dbo.testdb.testcolx = t2.testcolx
