Is this how it's done?
INSERT INTO student (
(SELECT DISTINCT a.*
FROM student_spring a, student_summer b
WHERE a.unique_key != b.unique_key)\
UNION
(SELECT DISTINCT b.*
FROM student_summer b, student_spring a
WHERE b.unique_key != a.unique_key)
)
I'm trying this but I keep losing data whenever I run this!
Also, how do I populate a database table from an XML file?
Thanx
Phil
