Hi Group,
Thanks to all those who replied about the Universal Translator. I am going to
wait and try to use MapInfo 7.8 on my other workstation, where the files were
originally created, instead of the 7.0 verion which is what I've been trying to
translate with. Hopefully it works!

Hi David,
Sum() is an aggregate function that sums exactly one column.
Try using: ( sum(a)+sum(b)+sum(c) ) / sum(d)

Hi Gerald,
You can't directly select the rows from th table B that are not in table A.
I think the way to do this is :
- create a new column in the table B named "common" (char 2)
- Update table B :
Table to update "Table B"
Column to update "common"
Gerald,
Give this a shot:
SELECT * FROM Table_B WHERE Table_B.PID NOT IN(SELECT Table_A.PID FROM
Table_A)
The principle is called a SQL-Sub Select. The SQL engine will first select
a list of PIDs from Table_A and then compare that list to the PIDs in
Table_B. SQL will only include those re
Mark
You can do this: Select street_name From Streets_File Group By street_name .
This will give you all differents street names only one time.

I think the whole expression has to be less than 256, but I can't remember.
The obvious suggestion is to break your SQL statement into sections or
abbreviate.
ex:
SELECT one.NGS_id INTO two
FROM one
WHERE (((one.NGS_id)>"1"));
SELECT two.NGS_id INTO three
FROM two
WHERE (((two.NGS_id)<"2"));
