Hello,
I was reading the MySQLmanual and became confused about myISAM and
commit/rollback.
Can someone explain what I have to do in my queries to garuanty the
dataintegrity of my db in case I use myISAM? Do I have to use the commit and
rollback statements or is this done by MySQL self?
Thanks in advance!

using SQLTransaction with the first SQLConnection object but the second
SQLConnection object does not have any SQLTransaction object.
I am inserting some data using the two command objects. The problem
happens when I try to do a rollback on the SQLTransaction object. The
rollback happens only before...

Hi,
The question is about how to check if the transaction is still active. Let's
say, that I am using a 3rd party stored procedure, that cannot be changed.
Sample is (Of course, the real one is much more complicated):
CREATE PROC test AS IF @@trancount > 0 ROLBACK TRAN
Now, I'm executing code:
tran = connection.BeginTransaction();

Is it possible to use the dblink and dblink_exec features from inside
pl/pgsql functions to mimic the behaviour of nested transactions by
calling another function or executing some SQL via the dblink (into the
same database)?
Does the SQL statement executed within the dblink sit in its own isolated
transaction/session? And would an error thrown in the dblink statement
abort the enclosing session that initiated the call?
What is the...

I have 8.1.5 on Windows 2003, when I do from CLP with auto commit off:
db2 update table set column=something
and then
db2 terminate
and then
db2 connect to db
db2 select updated column from table
the update is committed anyways, whereas the docs state that the update
is supposed to be rolled back (auto commit is off)
Does this indicate a bug or a mistake in the docs?

Hi,
This is being called in a C# loop within an ado.net transaction from C# 1.1
code. It is used to write large file data to a SQL Server database in
chunks, rather than in one go.
I had the stored procedure below, which worked until the image datatype was
changed to varbinary(max).
Now I get the following error:

Hello,
I am using Datasheet view when displaying my data.
The data are displayed in a "x,y" matrix wherein data can be directly edited
in the Datasheet.
Anything inputted in a certain cell is directly updated to DB.
I want to open the Form, input data but WILL NOT COMMIT then close the Form.
If I open the same Form again, the data shouldn't be changed because it wasn't committed.

Overview:
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,...
