Hey,
I'm going to give some background on my situation in case anyone can
point out a way around my problem altogether... for the problem
itself, please skip to the bottom of the post. thanks.
I've been having some problems with database performance... Several
threads are constantly attempting INSERTs of new records into a large
table - that is hundreds of thousands of records -large by my account
:-) The table has a VARCHAR field...

The meaning of REPLACE INTO is clear to me.
IF the new record presents new key values, then it is inserted as a new
record.
IF the new record has key values that match a pre-existing record, then
the key violation is ignored and the new record *replaces* the pre-existing
record.
But what about INSERT IGNORE?
Is this a synonym for REPLACE INTO - i.e. it does precisely the same thing?

I have created a SQL string the properly inserts a record in the table.
However, the insert does not occur at the end of the table. Instead
it inserts a record after the last record that I viewed. This would be
OK, except it assigns a autonumber to be one greater than the last
viewed record. This causes a duplicate autonumber. I know I can
change the autonumber index (Primary Key) to not allow duplicates.
How can I force the insert...

Being new to VB and programming, I'm not sure how to modify the

I'm trying to insert records in a table that has a "no duplicates"
index on two columns.
The following snippet shows where I started off...

However, if these two values exist already as a "key" combination then,

In a ASP applicatiuon, the FOrm has a textbox & a select list where
the admin can select multiple options. Basically the admin has to
enter the name of a new coach in the textbox & select the soccer clubs
which he will be coaching; thus he can select only one soccer club for
a new coach or multiple soccer clubs.
This is how I am trying it: When this Form will be submitted, the new
coaches name will be inserted in a MS-Access DB table...

I am interested in scanning web pages for content of interest, and then
auto-classifying that content. I have tables of metadata that I can use for
the classification, e.g. : "John P. Jones" "Jane T. Smith" "Fred Barzowsky"
"Department of Oncology" "Office of Student Affairs" "Lewis Hall" etc. etc.
etc.
I am wondering what the efficient way to do this in code might be. The dumb
and brute-force way would be to loop through the content...

I seem to have a few duplicates entries in a very large database.
My database has two identical tables. One is written to on a regular basis (every few seconds) and the other is used for queries, and updated from the write table on a daily basis.
I'm trying to get rid of duplicate entries for the queries, and I thought the most effective way to do this would be to run the query as

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,...
