database when the records are more than 90 days old. I'm running MySQL
version 4.0.12-standard. The db consists of around 620 MyISAM tables with
the following structure:

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 |

Using the the NumId from TitleData, I would like to delete the
corresponding row in Bookdata using pure SQL. I want it to delete all
rows in bookdata where the Titledata.NumID is a match to bookdata.id
The two tables are linked in that the NumId of table Titledata is
identical to the Id of table bookdata. I can, using ADO, loop thru
deleting one by one but I would like to do this in a pure SQL
statement. Is this possible? Any help is...

Hello,
I read several articles of newsgroup about the bulk delete, and I found
one way is to:
-create a temporary table with all constraints of original table
-insert rows to be retained into that temp table
-drop constraints on original table
-drop the original table
-rename the temporary table

Hi,
I'm writing a program in Visual C# 2005 Professional Edition.
This program connects to a SQL Server 2005 database called
"Generations" (in which there is only one table, called
"Generations"), and it allows the user to add, edit and delete the
various records of the table.

"IDPerson", NamePerson", "AgePerson" and "IDParent".

Start with two tables, parent records in one and child records in the other,
a one-to-many relationship. Create a select statement joining the two.
Display the query in datasheet mode. When I delete a row, only the child
record is deleted from the source tables; the parent record is still
there...which is what I wanted.
Now display fields from that query in a continuous form. When I delete a
record from that form, one of the child...

Hi.
I have a "union" table which results of a union of two tables.
Occasionally I could have duplicates, when the same PIN has been added
to both tables, albeit at different Datees/Times, such as:
PIN Name Added Date
100411 A 7/11/2007 10:12:58 AM
100411 A 7/17/2007 10:54:23 AM

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...

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...
