Hi All,
I want to lock 2 tables on 2 servers using TABLOCKX
hint. These tables function as semaphores in my
application. It means when the tables are locked
then other users will not be able to access them
and automatically they can not continue their works.
I have tried using the following code, but it
does not work. I always got the error :

(MSSQL2000) I have read the transaction/locking sections in the
MS-help, online and several books. What I want to understand is the
transaction behavior in single statements .
If I have a Table: "Letters" with 1 column "L" and the table presently
has rows{A,B,C,D}
Case 1 (Insert):
First start transaction T1 "SELECT * FROM Letters"
Next start transaction T2 "INSERT INTO Letters

I would like to use pissimistic locking for changing data on a database.
(Yes, I know what I'm doing, it will scale poorly!)
I tried it using a transaction with Isolationlevel "serializable".
I set the select, insert, update and delete command of the DataAdapter
to use this transaction.
If I open a Row for editing, any other client trying to change the same
row is blocked. But it is still possible to read the row which is locked

I'm having problem with using DAO recordset to append record into a
table and subsequent code to update other tables in a transaction. The
MDB is Access 2000 with the latest service pack of JET 4. The system is
client/server, multiusers based. The MDBs are using record locking.
Here is part of the code:
Dim wkSpace As Workspace, db As Database
Dim rstTrans As DAO.Recordset
Set wkSpace = DBEngine.Workspaces(0)

Hello,
I have a parent table(x_orders) and a child table(x_orders_contents),
with a cascade delete on the child table. In a after delete trigger of
the x_orders_contents table I'm updating a field in the x_orders
corresponding row. This works when I delete a row directly from
x_orders_contents, but seems to cause a lock when I delete a row from
the parent table and the delete RI constraint is used. Is there a way
to find if the RI...

I have an Access 2000 database behind a threaded Java application that
that can have have concurrent access to the same table (but not the same
record). The database is set up for shared access with "No locks" as the
default, so that optimistic record locking should take place, and "Open
databases using record-level locking" is selected. Each Java thread gets
a new connection to the database, then updates its record.

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...
