Most compilers define EOF as -1. I'm just putting my toes
in the water with a student's model named Miracle C. The
..h documentation of this compiler does state that when
scanf cannot fill any fields it returns EOF.
I have run some tests on scanf and, so far, I've not found
an EOF return.
For example: If the programer formats scanf for an int or

I have a function and am using cursor. All the columns I select in the cursor clause are BYTEA datatype.
I need to compare the after-fetch-value for two BYTEA columns which is temp2 and temp3 shown as below.
I don't think I can compare it because there is no record in temp table which I use for debug purpose.
Does anyone know how to compare the after-fetched-value for two BYTEA datatype in pgsql's function?

Table DDL below:
The tables I have contain Timesheet information. Each row in the
tblTSCollected table contains an entry for an employee into the
timesheet system, specifically by scanning the barcode on their badge.
A whole bunch of business logic periodically attempts to "pair" these
into logically matched scans. For example, some employees will scan in
and out of a single place of work. For these there will be a row

Hello,
I need to compare two columns in two tables and to find the rows with
partially matched result. For example, 'Jim' is deemed as matching
'Jimmy' and 'Jeff ' as matching 'Jeffery'. In Microsoft jet
(or in sql server similarly) this can be done by using:
"SELECT tableA.column1, tableB.column1 FROM tableA INNER JOIN tableB
ON tableA.column1 LIKE tableB.column1 & %".

In the followng stored procedure, 2 NULL columns (COMM) are selected into 2
different SP variables and compared for equal. They are both NULL, but do
not compare as equal. When the Not NULL columns (SALARY) are compared, they
do compare as equal.

I have 2 datatables. They are identical. I want to compare them by
cell's content. They are all same.
But dt1 == dt2 or
dt1.GetHashCode() == dt2.GetHashCode() doesn 't work.
There are big amount of rows in theese datatables . So i don 't want
to enumerate each rows. This is not efficient and unacceptable for my
current application.

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...

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,...
