数据类型长度如下
| TINYTEXT | 256 bytes | |
| TEXT | 65,535 bytes | ~64kb |
| MEDIUMTEXT | 16,777,215 bytes | ~16MB |
| LONGTEXT | 4,294,967,295 bytes | ~4GB |
报错 Row size too large. The maximum row size for the used table type,not counting BLOBs,is 8126. You have to change some columns to TEXT or BLOBs
如果增大 text类型 字段的内容，就会报上面的错误。Row size too large。表示行的内容太多了，
可以修改类型为 MEDIUMTEXT 或 LONGTEXT
