如何创建带有 MyISAM 引擎的 MySQL 表?
mysqlmysqli database
要创建带有 MyISAM 引擎的 MySQL 表,我们可以使用 ENGINE 命令。让我们首先使用 CREATE 命令创建一个表。
mysql> create table StudentRecordWithMyISAM -> ( -> Id int, -> StudentName varchar(100), -> StudentAge int -> )ENGINE=MyISAM; Query OK, 0 rows affected (0.26 sec)
上面,我们将 ENGINE 设置为"MyISAM"。
要检查表中有多少列,请使用 DESC 命令。
mysql> DESC StudentRecordWithMyISAM;
以下是输出。
+-------------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------+--------------+------+-----+---------+-------+ | Id | int(11) | YES | | NULL | | | StudentName | varchar(100) | YES | | NULL | | | StudentAge | int(11) | YES | | NULL | | +-------------+--------------+------+-----+---------+-------+ 3 rows in set (0.00 sec)
检查表是否以 MyISAM 形式呈现。
mysql> SHOW TABLE STATUS FROM business LIKE 'StudentRecordWithMyISAM';
以下是清楚地显示引擎是 MyISAM 的输出。
+-------------------------+--------+---------+------------+------+----------------+-------------+-----------------+--------------+-----------+----------------+---------------------+---------------------+------------+--------------------+----------+----------------+---------+ | Name | Engine | Version | Row_format | Rows | Avg_row_length | Data_length | Max_data_length | Index_length | Data_free | Auto_increment | Create_time | Update_time | Check_time | Collation | Checksum | Create_options | Comment | +-------------------------+--------+---------+------------+------+----------------+-------------+-----------------+--------------+-----------+----------------+---------------------+---------------------+------------+--------------------+----------+----------------+---------+ | studentrecordwithmyisam | MyISAM | 10 | Dynamic | 0 | 0 | 0 | 281474976710655 | 1024 | 0 | 1 | 2018-10-22 15:47:01 | 2018-10-22 15:47:02 | NULL | utf8mb4_unicode_ci | NULL | | | +-------------------------+--------+---------+------------+------+----------------+-------------+-----------------+--------------+-----------+----------------+---------------------+---------------------+------------+--------------------+----------+----------------+---------+ 1 row in set (0.14 sec)
检查 MyISAM 表是否存在。
mysql> SELECT TABLE_NAME, -> ENGINE -> FROM information_schema.TABLES -> WHERE TABLE_SCHEMA = 'business' and ENGINE = 'MyISAM';
以下是输出。
+-------------------------+--------+ | TABLE_NAME | ENGINE | +-------------------------+--------+ | studentrecordwithmyisam | MyISAM | +-------------------------+--------+ 1 row in set (0.00 sec)
