I'm using InnoDB with Mysql and I've used delete to delete over 10
million records, but the InnoDB database is still the same size on the
disk (over 100 gigs) is there a way to get Mysql/InnoDB to shrink or
trim this size?
and also, can I set a maximum size and make it so itll rotate itself,
as in purge out old entries as new ones come in when it hits the
maximum?
I'm not used to InnoDBs... so I could use some help with this...

When you create database diagrams in Enterprise Manager, the details
for constructing those diagrams is saved into the dtproperties table.
This table includes an image field which contains most of the relevant
infomation, in a binary format.
SQL Enterprise manager offers no way to script out those diagrams, so
I have created two Transact SQL components, one User Function and one
User Procedure, which together provide a means to script...

Hello,
I have ran a script in which I created a temporary table and dropped
the table at the end of the script. Unfortuantely not only was this
table dropped but all of the other tables in the database were dropped
as well.
Unfortuantely, the backups are made every day at midnight. So all of
the information for the past 23 hours has been currently destroyed.
What I need to know.

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:

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...
