Hi everybody!
My problem is as following:
I have a trigger which fires on delete of a table row. The body of the
trigger checks and manipulates entries in other tables.
If the entries have certain values, I would like the row of the table
which has fired the trigger not to be deleted. As far as I understood
this problem could be solved by a user defined exemption. But when

Hi gurus,
Anyone knows how to solve this? I was playing around with triggers on
my own machine which runs 7.3 and there it works okey, but when trying
it on 7.2 I get an error about duplicate keys. Upgrading to 7.3 on the
other machines is not possible yet. Any help on getting it to work
with 7.2 would be appreciated.

table group is made up of ID,parentID,groupHash and groupName.

One database tells on every connect statement:
SQL1092N "" does not have the authority to perform the requested command.
Another database at the same instance works fine.
One day before the first database worked too.
Any idea what could have happened and how I can connect again?
Thanks

Hi,
We have some datasets that are not linked to any form of database, it is
just a means for us to pass info about.
We need to perform an update on this dataset, based on a filter. Just like
an SQL statement, IE: UPDATE tableX SET Name = 'xxx' WHERE ID =xx
The only whay I can think of doing this is to perform a row filter on a
view, then loop through modifying each row manually.

Hi:
In postgres documentation its written that if we execute query as PERFORM query inside our stored procedure; then the special variable FOUND is set totrue if the query produced at least one row, or false if it produced no rows.
But FOUND variable is always returning true even my query is returning 0 records.
Please suggest me the solution.
Thanks and Regards,
Rajat.

I have one table in microsoft access database.
I need to perform calculation on a field- then a conditional statement between 2 fields.
field2 - needs to be multiplied by 5
the answer needs to be compared to field1.
I have to find out if field2( after multiplication) is less than field1.
then I have to have a report that gives me only the records where this is true.
any ideas about how I can do this?

Hello,
First, I know it's against "Access Law" to save calculations in a
table, but....I want/need to.
I currently have sub-totals being calculated inside a form, using
DMax, DCount, and DSum. But these aggregate functions are slowing down
the interface and annoying me. So I have decided not to show sub-
totals on the form.

Question could also be asked, how to compare data between two arrays and perform an action (print cmd) everytime there is a match?
The problem I'm having with the code below is that the comparison in the conditional IF statement is only happening against the first value --$link-- in the array --@route--
I want the comparison between the two arrays to repeat for every value in the first array @route.
Appreciate any guidance or ideas...

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:

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,...
