AUTO_INCREMENT in MYSQL generates a unique number when a new record is inserted into the table. If you want to automatically create the value of the primary key field each time you insert a new record, you can create an auto-increment field in the table.

An example of a statement that mysql creates a self-increasing primary key table:

CREATE TABLE `tablename` (`id` int (11) NOT NULL AUTO_INCREMENT, PRIMARY KEY (`id`)) ENGINE=MyISAM DEFAULT CHARSET=utf8

If you want to set automatic increment (auto_increment) when creating a table in mysql, it must be the primary key (PRIMARY KEY) setting, not NULL, and only one can be set.

# 1075-Incorrect table definition; there can be only one auto column and it must be defined as a key.

This error means: # 1075-the table definition is incorrect; there can be only one automatic column, which must be defined as the primary key.

If this error occurs, you need to check the table statement, and if you set self-increment, you need to set the self-increment field as the primary key.
