我应该为列使用哪种数据类型？ [MySQL的]

Question

I am working on a content management system at work. I will have a column to hold the body of our users' content (HTML) and I'm not too sure what column type to use. I don't want to arbitrarily assign a maximum length but I don't know if using a LONGTEXT or BLOB field is overkill.

Maybe someone could give me a tip or point me in the direction of some sort of "best practices" article for these types of things? :)

Any help is appreciated

Answer 1

I recommend reading http://dev.mysql.com/doc/refman/5.0/en/string-type-overview.html so you know the size constraints of each field. Afterwards you can choose based off your understanding of the application if you should allow more.

Text A TEXT column with a maximum length of 65,535 (216 – 1) characters

Medium Text A TEXT column with a maximum length of 16,777,215 (224 – 1) characters.

Long Text A TEXT column with a maximum length of 4,294,967,295 or 4GB (232 – 1) characters.

I think you should set some kind of limit. It might be worth looking into what other software does (like Word Press) for example.

As for ChaosPandion: GZip is binary, if you're going to do that he should be using BLOB instead.

Answer 2

使用LONGTEXT，以便您可以搜索它。

Answer 3

您应该GZip和Base64对HTML进行编码，然后将其存储在“文本”列中。
