Thread: Weird Update Behaviour

Good Day Everyone,

Here's something weird
So, i'm using VB and ODBC and I'm getting something weird weird weird
happening.  When ever a user updates this text field, it gets put all over
the same column.

So if low_bid_notes.Text = "Talk about frustrating" when the With
rs2.Update would execute, "Talk about frustrating" would appear all over
that column, not just on the row where quote_number =
data_estimating.recordset!quote_number

but on anywhere from 15 to 50 other rows.

    rs2.Open "SELECT low_bid_notes,low_bid_spread,low_bid_spread_percent,"
& _

   "addl_bid_notes,rebid,rebid_info,sales_person,date_complete,no_tabs_a
vail,only_bidder,negotiated,no_tabs," & _

   "dealer_bid,accept_date,date_modified,plan_deposit,plan_return_date,l
ow_bid_percent_sell FROM schedule WHERE
    quote_number='" & data_estimating.Recordset!quote_number & "'", cn,
adOpenKeyset, adLockPessimistic

cn is yer standard connection string that's worked time and time again.

With rs2
    .Fields("no_tabs").Value = chk_no_tabs
    .Fields("negotiated").Value = chk_negotiated
    .Fields("only_bidder").Value = chk_only_bid
    .Fields("dealer_bid").Value = chk_dealer_bid

    .Fields("low_bid_percent_sell").Value =
Format(txt_low_bid_percent_sell.Text, "general number")
    .Fields("low_bid_percent").Value = Format(txt_low_bid_percent.Text,
"general number")
    .Fields("low_bid_notes").Value = txt_low_bid_notes.Text
    .Fields("low_bid_spread").Value = Format(txt_low_bid_spread.Text,
"general number")
    .Fields("low_bid_spread_percent").Value =
Format(txt_low_bid_spread_percent.Text, "general number")
    .Fields("date_modified") = Now()

    .Update
    .Close


that's the code that's broken, here's what i did to fix it:

cn.Execute "update schedule SET low_bid_notes='" & txt_low_bid_notes.Text &
"'" & _
" ,low_bid_percent_sell ='" & Format(txt_low_bid_percent_sell.Text,
"general number") & "'" & _
" WHERE quote_number = '" & txt_quote_id(0).Text & "'"


instead of using the ADO recordset, i just did an execute command on the cn
connection.  when done like that, it works just fine.

So, my questions are:
What could cause this?  Is it an ADO or ODBC thing?  Am i forgetting to
close or set a recordset to nothing somewhere?  Thanks in advance and have
a good weekend.

I assume quote_number is your primary key. It also looks to be a text field
which I know MS Access & DAO (and I guess ADO is similar) translates to memo
field unless you have unchecked Text As LongVarChar in the PostgreSQL ODBC
driver options. When you update a recordset it updates on either primary key
and xmin if it can (if row versioning is enabled) or on every non-memo
field. I suspect that what is happening is that since your primary key
appears to be a memo field it isn't using it to tell which row to update
just the other none memo fields.
Hope this helps,
- Stuart
