My friend asked: I encountered a problem today. I have created a table and the index is REF. how can I write a piece of information and automatically generate a REF number to record it in the table? The REF number to be generated is continuous, starting from 00000. Obviously, this is a problem that anyone who uses MySQL will encounter.
Recall the MySQL GUI tool mentioned at the time of environment configuration, right, it is, you can find it in http://www.mysql.com. Because sunec is also a programmer, far from reaching the programmer level, it is necessary to use some tools to help ~ I believe some of my friends are the same as me ~
Use a GUI tool to create a table, create a REF field, set REF as the primary key, define the type as int, and check the auto inc option. All right, the work on the MySQL end is over.
Next, I handed it over to PHP. I used the insert command introduced in the previous topic to add data to this table. Note that I do not need to add the REF value because I checked the AUTO INC option, then, each time you add a record, the REF will be automatically generated and will increase in order. in this way, can you meet your needs?
In addition, from this topic, I have summarized some technologies into the PHP technology zone. please pay attention to them!
