OK but why? This is what auto-number does.
If you want to define the id yourself, don't use auto-number.

Note that MySQL doesn't care whether the ID of the first record is 1, 6 or 548633. Forcing MySQL to reset the AUTO_INCREMENT value of a table will not improve performance.

I have a table with quiz questions. Each question has a unique ID, based on an auto_increment field. Now I've discovered that with deleting rows from the table the deleted ID's are not reissued. Makes sense, just thought of that a bit late. How can I simply re-index or update or how one would call it, the columns holding the ID numbers ? Is there a ready-made mysql command or do I have to load all rows in PHP and modify where necessary ?...

I'm looking at setting up two mysql servers in replication with both being masters. The most obvious snag in this scenario is auto_increment, as disconnections between servers could allow user interaction to generate duplicate keys. In a moment of zen I thought, "What if one server dealt only in even numbers, and the other only in odd numbers?" This solution would keep things simple and manageable, while also keeping the servers off...

Hello, The first column of my table is AUTO_INCREMENT. I fill my table with 5 records with a blanco value in their first field. The first column of my table will then hold the values 1,2,3,4,5 (top>down). Then I erase those 5. Then I add a new record with a blanco first value. It will get number 6.

This question refers to a main form with a continuous form subform. After an error occurs after entering several records in the subform, how can I delete all the data in the main form and all the records in the subform? I have tried undoing both the main form and the subform and I have tried deleting the record in the main form. Thanks! Mark

I am migrating a database to MySQL 5.0. Several tables should have their primary key as an auto_increment integer. The database being copied has records with the primary key beginning with zero (0). These keys are foreign keys so it is not desirable to change their values. Here is what I have been trying: (1) Truncate table <tablename>; (2) Alter table <tablename> modify recid integer not null default 0; (3) <insert rows into table>...

From the mother table, the incentive is calculated datewise for each employee as per his shift duty. In...

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...

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,...
