What if we want to select records 16 - 25 (inclusive)?
Mysql also provides a way to handle this: by using OFFSET.
I have had requests for Su SE (another RPM-based distribution) as well as Debian-based systems, so I will work on variants of these directions for those distributions in the future (donations might help speed that process up! The main difference between the distributions is in the paths to the startup scripts. If you need an SSL-enabled server, I have a LAMP with SSL howto as well.
I designed this document so you can just copy/paste each line or block of commands into your shell session and it will "just work" for you.
This makes it much more effective for an update script.
$query = "UPDATE contacts SET first = '$ud_first', last = '$ud_last', phone = '$ud_phone', mobile = '$ud_mobile', fax = '$ud_fax', email = '$ud_email', web = '$ud_web' WHERE id = '$ud_id'"; This query tells the database to update the contacts table where the ID is the same as the value stored in $ud_id (which as you can see from the form on the previous page was set as the id of the record we are updating) and to set the following fields to the specified values (which were set using the form on the previous page).
In this part I will show you how to do the two final actions, updating your database and deleting records from it.Most popular storage engines are My ISAM and Inno DB. To fix a single table, connect to your My SQL database and issue a: If this doesn't help, there are a few additional tricks you can try. Multiple instances of My SQL This is pretty common.You restart My SQL and the process immediately dies.Changed Inno DB log settings Once you have a running Inno DB My SQL database, you should never ever change these lines in your /etc/file: Inno DB log file size cannot be changed once it has been established. My ISAM bad auto_increment If the auto_increment count goes haywire on a My ISAM table, you will no longer be able to INSERT new records into that table.If you change it, the database will refuse to start. Disappearing My SQL host tables I've seen this happen a few times. You can typically tell the auto_increment counter is malfunctioning, by seeing an auto_increment of -1 assigned to the last inserted record.
