Phpmyadmin #1075 - Incorrect table definition; there can be only one auto column and it must be defined as a key
The PHPMyAdmin error message "#1075 - Incorrect table definition; there can be only one auto column" occurs when you attempt to create a table with multiple columns defined as auto-incrementing (AUTO_INCREMENT). In MySQL, a table can only have one auto-increment column. To fix this issue, you can follow these steps:
Identify the table and columns: Review the table structure and identify the columns that are defined as auto-incrementing (AUTO_INCREMENT).
Determine the desired auto-increment column: Determine which column should be the primary key or the designated auto-increment column. This column will have the AUTO_INCREMENT attribute.
Remove auto-increment from other columns: Remove the AUTO_INCREMENT attribute from any columns that should not be the designated auto-increment column. You can do this by modifying the table structure and altering the column definition.
Set the designated auto-increment column: Ensure that the designated auto-increment column has the AUTO_INCREMENT attribute set. If it does not, modify the table structure and alter the column definition to include the AUTO_INCREMENT attribute.
Retry table creation: After modifying the table structure to have only one auto-increment column, attempt to create the table again. The "#1075 - Incorrect table definition; there can be only one auto column" error should no longer occur.
If the issue persists or you need further assistance, consult the documentation for your specific database management tool or consider seeking guidance from a database administrator.
