Hi,
I need to print a message when the number of rows returned from
repeating groups is > 3. How is this best done? I have two repeating
groups filtered to display only 3 rows. When either one returns more
than 3 rows, I need my text message to print.
Both repeating groups are using the same table. Different data is
being displayed. I'm using reports 6i.

i *thought* inner join should not return nulls, but not only that,
but i get way more rows than i'm expecting.

I have a table which is returning inconsistent results when I query

In query analyzer:
If I do "SELECT * FROM TABLE_NAME" I get no rows returned.
If I do "SELECT COL1, COL2 FROM TABLE_NAME" I get 4 rows returned.

Is there a way to get random rows besides ORDER BY random()? The problem with ORDER BY
random() is that is has to get all the rows from the table before the results are returned.

I'm implementing paging through search results using cursors. Is there a
better way to know total number of rows under a cursor than running a
separate COUNT(*) query? I think PostgreSQL is bound to know this number
after the first FETCH, isn't it?
On a side note, why queries using LIMIT are SO terribly slow, compared to
cursors and sometimes even ones without LIMIT? Shouldn't LIMIT be internally
implemented using cursor mechanism then?...

I'm delving into using ADO.NET for the first time. In fact, I've never
done any database work using C# at all so all of this is new to me.
Please bear that in mind if I am asking stupid questions.
In reading the documentation for the "Update()" method of the
SqlDataAdapter class, I see that it "Calls the respective INSERT, UPDATE,
or DELETE statements for each inserted, updated or deleted rows in the
specified array of DataRow objects"....

I am sure there must be an easy way to determine the number of

I appreciate the courtesy and patience ng members have shown this

Hi
I would like to write a SQL select statement that would fetch rows
numbered 50 to 100.
Let me clarify, if i say "fetch first 10 rows only", it returns the
first 10 rows from the resultset. how do I get a specific subset of
rows from the result set if I give a start and end value. For example,
retreiving rows 50 to 100 from the resultset.

I have looked through Python Database API Specification v2.0, but can
not find any reference to the number of records processed in a select
query.
I know I can get the number of records returned with cursor.rowcount,
but I want to know the number of records processed.
I suppose the info is in one of the internal tables, but I can not
find any info on that, because phpMyAdmin shows the number of rows in
a table.

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:

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,...
