I am not sure why the below join query is not returning any results.
SELECT * FROM table1 JOIN table2 ON table1.fieldid = table2.idfield
The below 2 queries return results so I am not sure why the join wont pick up any rows when i can clearly see that both tables have join field values in common.
SELECT * FROM table1 WHERE fieldid = 900399530 (returns rows)
SELECT * FROM table2 WHERE idfield = 900399530 (returns rows)
Any ideas?
Below are the data types for the 2 columns:
fieldid [nvarchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL
idfield [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL

As far as it's a CHAR/VARCHAR/NVARCHAR field you should use single quotes:
Maybe there is some extra or leading space.
Try it on this way:
or remove additional spaces by using TRIM() function.
