I had been just developing a new table using MySQL Query Browser, and observed there is a tick under Auto Increment Column. So how exactly does that actually work?

When contributing to the database programatically, will i just give a number, and so the database instantly batches time?

Each time a brand new user registers on my small site, I would like their Customer ID (integer only) to auto increment, and so i do not have to try to at random produce a unique number.

Is this done simply?

Thanks!

Yes, this is the way auto_increment works.

  • The worthiness is going to be incremented for every new row

  • The worthiness is exclusive, replicates aren't possible

  • If your row is erased, the auto_increment column of this row won't be re-designated.

  • The auto_increment worth of the final placed row could be utilized while using mySQL function LAST_INSERT_ID() however it must be known as immediately after the place query, within the same database connection

mySQL Reference

Whenever you enable Auto Increment an ID will invariably get instantly added each time a new record is created.. Example:

For those who have 1 record with ID one in your table and also you give a new record, the ID will instantly be 2.

Yes, this is the exact reason for AUTO_INCREMENT. It appears at whatever may be the current increment value for your table, and stores that value plus 1 for that new row that is available in, instantly. You are able to omit that area out of your INSERT claims and MySQL will handle it for you personally for each new row that is available in, giving each row its very own unique ID.

another, You are able to place your personal value also (ie your random value).

Yes. Auto_Increment posts work like they are saying around the container. Tips

  • when Place - ing, use NULL or omit the column

  • Use LAST_Place_ID() (or API counterparts) to get the last produced value.

  • for security and business logic reasons, it's often better form not to directly make use of a key value for any customer identifier. Think about using Hashed / randomised surrogate customer secrets rather.
