am using FOR UPDATE triggers to audit a table that has 67 fields. My
problem is that this slows down the system significantly. I have
narrowed down the problem to the size (Lines of code) that need to be
compiled after the trigger has been fired. There is about 67 IF
Update(fieldName) inside the trigger and a not very complex select
statement inside the if followed by an insert to the audit table. When
I leave only a few IF-s in the...

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...

Hello all,
I have a DataTable which I am building column by column and adding rows
after each new column. The DataTable columns match the columns in my
database table. I'm building the DataTable first and I then want to roll
through the DataTable while in memory checking for errors and then commit
the rows to my database table (btw this is in ASP.NET). Is it possible to
have data in a datable before attaching at DataAdapter? I'm a...

I am using Visual Studio 2003 and am getting lousy performance after using
a datatable select and then trying to assign a value to a column of the row
that was found:
DataTable dt = new DataTable();
dt.Columns.Add("Number", System.Type.GetType("System.Int32"));
dt.Columns.Add("Value", System.Type.GetType("System.Double"));

I'm using a DataTable in my application. I am able to load rows into the DataTable quickly. What's puzzling me, however, is that when I update a set of cells in the DataTable, the update is really slow
my update code amounts to
dataTable.BeginLoadData()
dataSet.EnforceConstraints = false
tr
for(iRowHandle = 0; iRowHandle < iLimit; iRowHandle++

I've been bothered for some time about my DataGrid not populating my rows
very quickly. I have about 10K rows loading into the grid.
I create a datatable dt with 2 columns, an ID and a display. The ID is a
member of the keys array.
I then create a DataView dv over the table, and sort it by Display and ID
column (in case of duplicate Display).
I then set my DataGrid.DataSource = dv;
I then load the datatable with my rows, and this is...

Hi - can anyone comment on why performance would be so
slow to update a DataTable row a simple value? With 3000
rows, it takes 5 seconds, which is unacceptable. Sample
code below. Suggestions?
string colName = "seg_qty";
for (int i=0; i<mwbView.Count; i++)
{
mwbView.Row.BeginEdit();
mwbView.Row = 0;

I fill a DataTable with search results, which take a very long time if
I first clear it. The values come from an object and I map them into
the corresponding table columns. I may have 65000 results. I iterate
through them, create a new row, fill it, and add it to the DataTable
for each interation. This works fine on the first search.
Before each search, I call DataTable.Clear() and do the above process.
Every search after the first...

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
Here is the code in...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
