可以把字段类型改成MEDIUMTEXT(最多存放16777215个字符)或者LONGTEXT(最多存放4294967295个字符).。
MySQL supports 4 TEXT field types (TINYTEXT, TEXT, MEDIUMTEXT and LONGTEXT) and this post looks at the maximum length of each of these field types.。
MyISAM tables in MySQL have a maximum size of a row of 65,535 bytes, so all the data in a row must fit within that limit. However, the TEXT types are stored outside the table itself and only contribute 9 to 12 bytes towards that limit. (For more information about this refer to the MySQL Manual - Data Storage Requirements chapter).。
TEXT data types are also able to store much more data than VARCHAR and CHAR text types so TEXT types are what you need to use when storing web page or similar content in a database.。
The maximum amount of data that can be stored in each data type is as follows:。
TINYTEXT 256 bytes 。
TEXT 65,535 bytes ~64kb。
MEDIUMTEXT 16,777,215 bytes ~16MB。
LONGTEXT 4,294,967,295 bytes ~4GB。
In most circumstances the TEXT type is probably sufficient, but if you are coding a content management system it's probably best to use the MEDIUMTEXT type for longer pages to ensure there are no issues with data size limits.。
觉得还是文学比较好找资料,最好先定下几个备选题目,在网上搜搜看哪个作品或作者的材料比较多,但如果太多赏析的话也不好,再写的话就觉得很难找到新的研究方向了。
