Question

我在MySQL中遇到了这个问题，因为我创建了一个视图，但是当我浏览时;我得到以下错误，行大小限制超过阈值。

SQL Error (1118): Row size too large (> 8126). Changing some columns to TEXT or BLOB or using ROW_FORMAT=DYNAMIC or ROW_FORMAT=COMPRESSED may help. In current row format, BLOB prefix of 768 bytes is stored inline.

然后我搜索了我的解决方案如下 Change limit for "Mysql Row size too large"

适用于OP的方法有：

将以下内容添加到my.cnf部分下的[mysqld]文件中。
```
innodb_file_per_table
innodb_file_format = Barracuda
```

ALTER要使用的表格ROW_FORMAT=COMPRESSED。

ALTER TABLE nombre_tabla
ENGINE=InnoDB
ROW_FORMAT=COMPRESSED 
KEY_BLOCK_SIZE=8;

这里的问题是我无法ALTER VIEW ENGINE=InnoDB, ROW_FORMAT=COMPRESSED, KEY_BLOCK_SIZE=8

ALTER VIEW  view_dashboard
ENGINE=InnoDB
ROW_FORMAT=COMPRESSED
KEY_BLOCK_SIZE=8;

我收到ALTER VIEW的问题，如下所示

SQL Error (1064): 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       

ENGINE=InnoDB
ROW_FORMAT=COMPRESSED
