I have a DELETE statement that deletes duplicate data from a table. It
takes a long time to execute, so I thought I'd seek advice here. The
structure of the table is little funny. The following is NOT the table,
but the representation of the data in the table:
+-----------+
| a | b |
+-----+-----+
| 123 | 234 |
| 345 | 456 |

Access 2000:
I am trying to delete duplicate records imported to a staging table leaving one
of the duplicates to be imported into the live table. A unique record is based
on a composite key of 3 fields (vehicleID, BattID, and ChgHrs). VehicleID and
BattID are a TEXT datatype and ChrHrs are a number(long int.) datatype. Since
records to be imported can have duplicate records of the composite key I need to
clean all but one of the...

Thanks in advance.

I have a table with what I consider duplicate records. Data in all columns are duplicate except for the date column, meaning that duplicate data was entered on different dates and those dates were stored along with the data.
I want to delete the records except for most recent one. I can select the client ID field and the max(date field) to determine the ones I want to keep, but how do I determine the ones to delete. There are often more than...

Hi All,
I want to delete duplicate records from a large table.
There is one index(INDEX_U1) on 4 columns(col1,col2,col3,col4) which is in unusable state.
First of all when i tried to rebuild index it showed error as unique key violation.
So i want to delete duplicate records for col1,col2,col3,col4 combination.
How can i delete the duplicate records from this large table?

Hi all. My ultimate goal is to return two columns, where no single value appears anywhere twice. This means that not only do I want to check that nothing from column A appears in column B and vice-versa, but I also don't want the same value appearing twice in A and twice in B.
So far I have:
--Diff the columns
INSERT INTO @Table
SELECT One, Two
FROM @Column1 a
FULL OUTER JOIN @Column2 b

Hi -
I am trying to delete duplicate records from a single table. The table has multilple records of duplicate purchase orders. In these instances I need to delete those records that have the same $amt but different qty.
I have already created the delete query but am unsure how to specify the criteria which should be based on the $amt and qty.
Simply said, I need the code to remove all Duplicates with the same $ but different qty. ...

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...

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...
