Hi
I have a SQL2000 server with 128m rows of data. I want to delete about
65m of that. So far I have bcp'ed the relevent data out and put them
into another SQL database.
We have a small amount of space for our transaction log so I cannot
delete all 65m rows in one go. So far I have been doing them is 0.5m
chuncks, but it is extremly slow.

I'd like to run a clean up command on my tables to
eliminate rows that I'm no longer using in the database.
I want to do something like this:

WHERE IS_REFERENCED_BY_FOREIGN_KEY IS FALSE;
Does anyone know how something like this could be done
in PostgreSQL? I know I can search all the tables that

Hi to all,
I don't understand that: I try to delete a record via JDBC. But I always
get the error SQL7008 with the error code 3. It seems that this has
something to do with journaling, since the table from which I want to
delete has two foreign keys that references two other tables and it is
also referenced by another table. But this shouldn't be a problem, since I
set the commit mode to none (or *none) at all places where this makes...

Hi All,
Sorry that I am Asking this question in this Group.
I have one doubt in SQL Server, Regarding how DELETE Works?
What is the Actual Thing that SQL Server Do when we delete any record from
the Database Table?
Does it maintain any Falg Internally or actually Delete the Record from
Database?

Hi,
Thought perhaps some other eyes than mine can tell if I'm doing
something wrong here or if there's a bug somewhere. I've never
passed a ROWTYPE varaible to a function but I don't see where
the problem is.
I keep getting errors like (the first is my debug output):
NOTICE: last cycle is: 11
WARNING: Error occurred while executing PL/pgSQL function

I have a base customer table of 2 million records. We're doing some
testing and I added 33000 rows incorrectly. No biggie, we'll just
delete them, right? Nope....9 hours later, process is still running
using this query.
delete from customer where custid in (select custid from #tmp1)
k...so we'll change it.
delete from customer where custid > 2295885

Hello
I had a question reagrding MSDTC usage. I know that MSDTC will enlist
each connection transactions as it's own (take ownership) and
commit/abort accordingly.
However I'm not sure what would happen where I have a stored proc with
input parameters and 2 Delete commands on 2 different tables. In this
case, would MSDTC also enforce ACID rules when 1 cmd succeeds and 2nd
aborts ? In the script for the Stored Proc, there is no checking...

I am writing a DELETE statement and I want to filter the records using
another SELECT statement.
My SELECT statement is a GROUP BY query that grabs all social security
numbers from the "Data With Import Date Current" table on a given day
where there was only one transaction (count of SSN = 1). I want to
delete these records from the "Data With Import Date Current" table.
I would like to do this by joining the "Data With Import Date...

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...

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
