Re: inner join SQL

Hi Paul,

You don't have POSITIVE and NEGATIVE in T2 so you should get an error
"Column not in table T2".

After I placed both in T2 and my change earlier, it worked for me and
produced 5 rows.

Yours truly,

Glenn Gundermann

Hi Paul,

I'm not at my computer but give this a try:

Change:
(T2.POSITIVE = T1.POSITIVE) OR (T2.NEGATIVE = T1.NEGATIVE)

To:
(T2.POSITIVE = T1.POSITIVE OR T2.NEGATIVE = T1.NEGATIVE)

 I am expecting to see my outfile from this SQL  have all 5 records from
file2 ( they match with file1 on the conditions above), but  i am
getting
only 4records match.
Can someone tell me what need to be fixed in my SQL to get all 5
records.
I am having troule with record for account 1234C.
For account 1234C I have two records and they both match to 1234C record
in FILE1(if you see T2.positive = t1.POSITIVE AND T2.NEGATIVE =
T1.NEGATIVE)
