Describe the problem

We can change the starting value for the AUTO_INCREMENT field if you don't want to start at 1.
But setting AUTO_INCREMENT starting value does not work in Tianmu engine.

mysql> CREATE TABLE st8 (
    -> id INT NOT NULL AUTO_INCREMENT,
    -> name VARCHAR(20) NOT NULL,
    -> PRIMARY KEY(ID)
    -> )AUTO_INCREMENT=100;
Query OK, 0 rows affected (0.04 sec)

mysql> select * from st8;
Empty set (0.02 sec)

mysql> INSERT INTO st8 (name)VALUES('Java');
Query OK, 1 row affected (0.00 sec)

mysql> select * from st8;
+----+------+
| id | name |
+----+------+
|  1 | Java |
+----+------+

Expected behavior

mysql> CREATE TABLE st8 (
    -> id INT NOT NULL AUTO_INCREMENT,
    -> name VARCHAR(20) NOT NULL,
    -> PRIMARY KEY(ID)
    -> )AUTO_INCREMENT=100;
Query OK, 0 rows affected (0.00 sec)

mysql> select * from st8;
Empty set (0.00 sec)

mysql> INSERT INTO st8 (name)VALUES('Java');
Query OK, 1 row affected (0.00 sec)

mysql> select * from st8;
+-----+------+
| id  | name |
+-----+------+
| 100 | Java |
+-----+------+
1 row in set (0.00 sec)

How To Reproduce

CREATE TABLE st8 (	
id INT NOT NULL AUTO_INCREMENT,
name VARCHAR(20) NOT NULL,
PRIMARY KEY(ID)
)AUTO_INCREMENT=100;

INSERT INTO st8 (name)VALUES('Java');

select * from st8;

The issue is not fixed @wisehead

[haitaoguan]

In tianmu engine, the table structure will not display keyword "AUTO_INCREMENT".

[haitaoguan]

If you set auto increment, the table structure will display keyword "AUTO_INCREMENT". Otherwise,you won't know what value to take next time.
