How can I view the current auto-increment values of database tables?
Because the auto-increment field of the database table is unique, after a record is deleted, the auto-increment value of the record actually exists, therefore, if you want to query the current starting value of the auto-increment field of the current table, it is wrong to query it by using select max ('auto-increment field ') from 'table name, I have tried the following methods.
You can use the following statement to query a MySQL database:
Show create table 'table name ';
The following result is displayed:
========================================================== ============================
Create table 'table name '(
...................
) ENGINE = MyISAM AUTO_INCREMENT = 3246 default charset = utf8;
Note that the above 3246 indicates the current auto-increment start value.
When you run the preceding SQL command using phpmyadmin, it is estimated that a scaling result is displayed. Click the option and select the complete text to view the result.
