Hi there,
I have a small question:
I have a table with lots of rows in it. Of course all have a different id,
but each can be assigned to a certain category. Categories correspond
with 1 - 10.
So a row looks like this: 'unique id | 4'
What i want is to do a count how much rows belong to a certain category.

I have a table with 5,100,000 rows.
The table has three indices.
The PK is a clustered index and has 5,000,000 rows - no other

The second index has a unique constraint and has 4,950,000 rows.

I have a window application. In one of the form, a datagrid has a dataview
as its datasource. Initial filtering result would give the datavew 3 items.
When I double click on the datagrid to edit the selected lie item at which

the dataview.count would return 0. I get a error message because I tried to
get values out of a dataview that holds 0 items. Does anyone...

Hallo,
Indeed, a count of a query with a group by function gives more records than
there are and so for-next structures don't function.
How is this to be mended.
Anyone? Everyone in fact.
Answers are greatly appreciated.

I have a table which has a million records. Each night it get trashed and
re-built.
I want to run a select statment and pass the results into a variable to let

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,...
