Incorrect column specifier for column 'ssid SSID'

When a data table is generated using hibernate, Hibernate executes the following SQL statement:


Create Table address (addressid varchar (255) not null auto_increment, name varchar (255), primary key (addressid ))


When log4j check is used: hibernat prompts the following error:

10:56:24, 546 error schemaexport: 274-unsuccessful: Create Table address (addressid varchar (255) not null auto_increment, name varchar (255), primary key (addressid ))
10:56:24, 546 error schemaexport: 275-incorrect column specifier for column 'ssid SSID'



The original auto-increment column uses the int data type instead of varchar.


Hibernate uses the code in address. Java

Private string addressid;
Private string name;


This specifies the "addressid varchar (255) not null auto_increment"


If the column is automatically increased, you can either change the addressid to the integer type or change the ing file to another primary key generation policy.
