Can I create a new table with an old table's autoincriment status in mysql client?
I think, that ALTER TABLE new_table_name AUTO_INCREMENT=@my_autoincr_iment
helps me, but this construction must use with a constant value.
I don开发者_如何学Go't want to use a difficult script.
mysql> create table new_table like old_table;
mysql> select @my_auto_increment:=auto_increment from information_schema.tables where table_name='old_table';
mysql> set @query = CONCAT("alter table new_table auto_increment = ", @my_auto_increment);
mysql> prepare stmt from @query;
mysql> execute stmt;
mysql> deallocate prepare stmt;
Thx to my brother!
Your CREATE TABLE can specify the auto_increment to use:
mysql> create table foo (i int primary key auto_increment, s varchar(12)) auto_increment = 10;
Query OK, 0 rows affected (0.19 sec)
mysql> insert into foo (s) values ("s");
Query OK, 1 row affected (0.09 sec)
mysql> select * from foo;
+----+------+
| i | s |
+----+------+
| 10 | s |
+----+------+
1 row in set (0.03 sec)
