Hello,
I have a vb.net web app that I am doing reads and adds to a database.
Everything works fine and happens instantly. I recently added an update and
it takes a long time to finish. I was wondering if there was anyone else who
experenced this problem and if there are any ways around it?
Dim MySQL As String
MySQL = "UPDATE db SET Var1 = 'Y' WHERE aimtno = " & tnum & "
and abook = " & tbook
Dim strConn As String = "Provider=IBMDA 400; Data
source=datasour ce; user id = " & tuserid & "; password = " & tpass & ""
Dim MyConn As New OleDbConnection (strConn)
Dim cmd As New OleDbCommand(My SQL, MyConn)
cmd.Connection. Open()
cmd.ExecuteNonQ uery()
MyConn.Close()

If it is updated eventually then do check with your system resources.

Will do, but I have a 2.8 P4 with a gig of ram. I would think that I would
have enough resources to update one field.

You are asking it to set a field to Y for each record that satisfies 2
values, which could be none up to every record in the database. Maybe it is
updating more records than you are expecting?
Have you looked at the obvious yet, Indexes?
Are the criteria fields indexed? If not, it will search all the records the
hard way looking for which ones to update. This can be painfully slow as you
database gets large.

Hi There,
I have an update statement to update a field of a table (~15,000,000
records). It took me around 3 hours to finish 2 weeks ago. After that
no one touched the server and no configuration changed. Until
yesterday, I re-ran it again and it took me more than 18hrs and still
not yet finished!!!
What's wrong with it? I can ran it successfully before. I have tried
two times but the result was still the same.

Hello All,
Any reason why a select query that runs will not run as an update

What I've done is created a select query that runs successfully. The

Here's one that should probably have the sub-heading "I'm sure I asked this
once before, but ...".
Two users are both looking at the same data, from a database. One user
changes the data and commits it. How does the other user get the updated
view without polling for changes? Is there some sort of callback mechanism
that can be set up on the dataset or connection?
TIA

Hello grp!
i'm using INNODB tables which are using frequently .
if i fire a SELECT query which fetch major part of table it usually
take 10-20 seconds to complete.
in mean time if any UPDATE qry comes for a perticular row which is part
of SELECT qry i want to know that whether UPDATE will wait for
completing SELECT qry or not,
or it simply executing without bothering SELECT qry .

I will ask the question first then fumble thru trying to explain myself so i
dont waste too much of your time.
Question / Statement - Every mdb table needs a PrimaryKey ( or maybe an
index - i havnt tested the index yet ) so you
can use an .UPDATE( dataTable ) on the data adapter. Otherwise you will
get an exception error.
Is this statement true?

Dear all,
I did a query which update a sequence number (column NR_SEQUENZA) in a table using a nice code (from Trevor !).
1) Given that I'm not a programmer I can't understand why numbering doesn't start always, running more times the update query, from the same starting parameter assigned (1000000000).
It seems to me that it takes memory last number calculated and running prox update it starts from last table row updated. I need...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
