我计划在我的数据库上储存一个<代码>json_encoded。 我可以确切地说明它所花时间,但我很相信它会很长。 我的关切是,我将为此目的使用哪一种实地类型?
我更喜欢这样一点,即我能够尽量节省空间,而不是快速搜索,不管怎样,我还有其他一栏,我应该只是索引。

<代码>blob通常适用于像图像、双版等内容。 如果你真的担心,那么你就应当使用<条码>长期<>>,这种编号甚至具有更大的空间能力。
搜索-噪音,因为你正在存储json_encode
。 d st,你仍然需要打上<条码>json_decode,因为这对你的申请有用,我不认为在这种情况下选择数据类型事项。
更好的办法是使你的数据库设计正常化,而不是在一个大街上储存相关的 st。
As stated in the documentation of MySQL, since 5.7.8 a native JSON data type is supported.
JSON数据类型提供这些优势,可以把JSON-format探测器储存在一栏中:
因此,正如MySQL文件所述,应当使用JSON数据类型,而不是文本。
