以下是错误,当您错误地实施ZEROFILL时会发生-
mysql> create table DemoTable -> ( -> StudentCode int(10) NOT NULL ZEROFILL AUTO_INCREMENT PRIMARY KEY -> ); ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ZEROFILL AUTO_INCREMENT PRIMARY KEY )' at line 3
为了正确实现,请使用以下语法-
yourColumnName int(10) ZEROFILL NOT NULL AUTO_INCREMENT PRIMARY KEY
让我们首先创建一个表-
mysql> create table DemoTable -> ( -> StudentCode int(10) ZEROFILL NOT NULL AUTO_INCREMENT PRIMARY KEY -> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values(); mysql> insert into DemoTable values(); mysql> insert into DemoTable values(); mysql> insert into DemoTable values(); mysql> insert into DemoTable values();
使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
这将产生以下输出-
+-------------+ | StudentCode | +-------------+ | 0000000001 | | 0000000002 | | 0000000003 | | 0000000004 | | 0000000005 | +-------------+ 5 rows in set (0.00 sec)
