What is wrong with this SQL,
-> );
ERROR 1075 (42000): Incorrect table definition; there can be only one auto column

SQL

CREATE TABLE TABLENAME12
(
TAB_ID INT NOT NULL AUTO_INCREMENT,

NAME_FIRST NVARCHAR(200),
TYPE NVARCHAR(200)

);

I am using mysql, how can I solve this. I am trying to create a table. and I get this error

Answer 1

The simular result you’ll get with

CREATE TABLE TABLENAME12
(
  TAB_ID INT NOT NULL AUTO_INCREMENT,
  NAME_FIRST NVARCHAR(200),
  TYPE NVARCHAR(200),
  PRIMARY KEY( TAB_ID )
);

This is also usable with other db’s as mysql except the type definition int and nvarchar.
if you use varchar and integer instead you are compatible with postgresql.
