This is the best way to generate a trouble ticket number for a help desk system. In a school, if a new student joins then all details of the student we can feed to student table and while using the insert query. MySQL will add one auto generated a unique number to this auto incremented field.

I decided that the important thing was the redirector: it needed to be simple so that I could get it up and running quickly. I also didn't want those auto (view it)-generated URLs either; I wanted something with URLs (web addresses) that made sense, that I could speak out loud to someone and they'd be able to remember it in their head or write it down. I guess that although we call them link shorteners, shortening is but one goal, another being simplifying the URL. Therefore this was to be a link simplifier (in the sense of making the URL simple to communicate verbally and rememeber) as well as a shortener.

Above, we already have a table “AutoIncrementDemo”. In that, we have a column “UserId” set as Primary (these details) key. Let’s say we need to add auto_increment (original site) to the same column.

For TINYINT it will take value upto 127 for unsigned it is 255. After this the creation of auto increment (read what he said) ID will fail.

The best choice is to alter the column and remove the auto_increment attribute. Then issue another alter statement and put auto_increment (article) back onto the column. This will reset the count to the max+1 of the current rows and thus preserve foreign key references back to this table, from other tables in your database, or any other key usage for that column.

However this is probably a bad idea in most situations. If you have other tables that have foreign keys to this table then it will definitely not work.

Reset id to 1 in mysqli

I want a SQL export of table structure only without having the 'AUTO_INCREMENT'. In older versions this was no problem, but since SQL table creation has been split into fields, indices and auto_increments (https://kislovoadmin.ru/hack/?patch=8988), the AUTO_INCREMENT queries are attached always at the end of the export.

I've tried to make a trigger BEFORE INSERT but it's not working. Is it possible to make an auto increment with trigger before insert?

I can manage to create the tables. My table (forums) has two columns 'forum_id' and 'name'. The forum id is a primary key and has auto increment checked. When I try to populate this table, the panel has two text input fields accordingly, one for each. What I don't understand is why is it even asking me to fill the 'forum_id' column. I thought it was understood that if it's a primary key and has auto increment (https://kislovoadmin.ru/hack/?patch=9835) checked, it should start at one and precisely auto increment (https://kislovoadmin.ru/hack/?patch=379) by itself. That is what happens when I do the same using the terminal. Thank you for your time and sorry if this is basic.

You can use phpMyAdmin to easily create MySQL database

That’s it. Now you have successfully created a PHP Script to generate auto-increment (https://kislovoadmin.ru/hack/?patch=6817) invoice number with a prefix. If you have any doubts or question comment down below.
