SYMPTOMS
The Full Outer Join SQL-SELECT command returns an empty result set when one of the tables or cursors is empty.



STATUS
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem has been fixed in Visual FoxPro 5.0a.



MORE INFORMATION
The Full Outer Join should return all the records from both tables or cursors. If one file is empty, then a Full Outer Join should return all the records from the other table.

Steps to Reproduce Behavior
Create a program file and add the following code: CREATE CURSOR cur1 (id_1 I(4), desc_1 C(20)) CREATE CURSOR cur2 (id_2 I(4), desc_2 C(20)) ** Places 10 records in cur1 FOR l_n = 1 TO 10 INSERT INTO cur1 (id_1, desc_1) VALUES (l_n, "TABLE1__" + ;       ALLTRIM(STR(l_n))) ENDFOR ** Performs full outer join SELECT * FROM cur1 FULL OUTER JOIN cur2 ON id_1 = id_2 The Browse window displays an empty result set.
