Column Name Length problem?

От

Good Morning Everyone,
I had a perfectly good working application written in VB that tied to a PG database on a Red Hat system with the latest ODBC driver.
After working on the app for awhile, I had to re-write the database layout based on user requests.  I made some field names longer and others shorter, and generally "neatened things up".  Why does "neatening things up" always break it? :). 
Of course, I didn't document the old layout, so I can't compare where things went wrong.  (Mental note, save printouts of the database layout)
On Friday, "select * from schedule" in the recordset.open statement would cause a "division by zero" error.  In debugging it, I got up to "select id,quote_number,price_required,bid_date,bid_time,project_name from schedule" before I had to leave for the day.  On Monday morning I'm going to start debugging the app from that point, but I was wondering if anyone could see anything that I would need to watch out for in the layout below.  Or that would cause select * to bomb out.
thanks in advance
corey

What kind of access method are you using ?
Aren't you using link tables ?

Good Morning Hiroshi,
That's the weird part, it links up in Access via a linked table ok.
In the VB program i'm using ADODB as shown in the HOWTO on the odbc site.  It used to work :).  I'll turn on the sql
logand see what it's telling me.

Good Morning Hiroshi,
I think this problem is a VB related issue.  Once i split the statement into two select statements, it worked just
fine. Access97 had no problem with linking the table, but VB seems to be choking on this long string of data.  I
checkedthe log file, and it fetched the record requested, so it's not the ODBC driver.  I did the split right after
"spread_percent"and just put the additional columns into a second recordset. 
thank you
corey
