SQL join question

[rick baird <rick.baird@xxxxxxxxx>]

I have two identical files, keyed uniquely by the same fields.

the first will have records that may or may not exist in the second
and the second will also contain records that may or may not exist in
the first.

I need an sql select statement (or DDS join if that's my only option)
that will pair these records side by side, showing all records in both
files, like this:

contents of file1

key1 description1
a    description
b    description
c    description
d    description
e    description

contents of file2

key2 description2
c    description
d    description
e    description
f    description
g    description

result of select - join

key1 description1    key2 description2
a    description     -    -
b    description     -    -
c    description     c    description
d    description     d    description
e    description     e    description
-    -               f    description
-    -               g    description

a left outer join will not include the f or g records in the second
file, and an exception join won't show the c,d,e records in either
file.

what's a mother to do?

thanks,

Rick
