I am having performance issues on a SQL query in Access. My query is
accessing and joining several tables (one very large one). The tables are
linked ODBC. The client submits the query to the server, separated by
several states. It appears the query is retrieving gigs of data from the
table and processing the joins on the client. Is there away to perform more
of the work on the server there by minimizing the amount of extraneous table...

Hi,
I have been running some queries against a table in a my database and
have noted an odd (at least it seems odd to me) performance issue.
The table has approximately 5 million rows and includes the following
columns:
DocID (INTEGER, PRIMARY KEY, CLUSTERED)
IsRecord (INTEGER, NONCLUSTERED)

I have a stored procedure that queries a database using a Select
statement with some inner joins and conditions. With over 9 million
records it takes 1 min 36 sec to complete. This is too slow for my
requirements.
Is there any way I can optimize this query. I have thought about
using an indexed view. I haven't done one before, does anyone know if
this would have potential to improve performance or indeed any other
performance...

I have a stored procedure that suddenly started performing horribly.
The query plan didn't look right to me, so I copy/pasted the code and
ran it (it's a single SELECT statement). That ran pretty well and used
a query plan that made sense. Now, I know what you're all thinking...
stored procedures have to optimize for variable parameters, etc.
Here's what I've tried to fix the issue:
1. Recompiled the stored procedure
2. Created a new,...

I am trying to get a sense of requirements and best practices for Java
stored procedures in DB2 V7.2 for Windows.
1. Is it required or recommended that any of the following be closed before
leaving the stored procedure: open Statement and PreparedStatement objects;
open ResultSet objects; open JDBC connections? Although the stored procedure
will still run succesfully if these open objects and connections are not
closed, are there any...

I previously posted about a problem where it seemed that changing the
case of the word "BY" in a SELECT query was causing it to run much much
faster.
Now I've hit the same thing again, where basically almost any change I
make to how the query is executed (so that it still performs the same
function) causes the performance to jump from a dismal 7 or 8 seconds
to instantaneous. It's a very simple query of the form:
SELECT Min(MyValue)...

I'm working on a project that was dropped in my lap. It is in Access
2003. There are short time fields which get calculated values (eg.
1:30). But I will need to total up those values for reports in
qiueries. When I tried to drop one of the fields in the query builder
and used the total function the totals was way off.
So I was wondering what would be the best way to do this? Thanks in
advance for the help.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

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,...
