How does one retrieve the rows in a select statement that DONT match the
select.
select CarIndex FROM DealerCatalog, BigCatalog WHERE
DealerCatalog.CarIndex=BigCatalog.CarIndex
finds all the cars in the dealer catalog that are in the bigger distributor
catalog.
How do I do the opposite in a single sql statement i.e. all the dealer cars

Hi,
I'm a newbie and I'm attempting to learn howto create a select statement.
When I use
>>> string1='18 Tadlock Place'
>>> cursor.execute("SELECT * FROM mytest where address = %s",string1)
All works as expected. But
>>> numb=10
>>> cursor.execute("SELECT * FROM mytest where clientID = %d",numb)
Traceback (innermost last):
File "<stdin>", line 1, in ?

Hi Experts
I am new to .NET. I need great explanation for "the updation in the disconnected data". How it is handled. That is, if mutiple user is interacting with the data, one will delete another will insert or update. So after the modifications how the correct updation is made in the database table. What the hidden mechanism is there. The updation logic is confusing

locking technics.

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...
