I have to store large amount of HTML data in a database .
I have Googled a开发者_JAVA百科nd found something about the blob
datatype, I checked it and it is working correctly.
I need to store the HTML pages in the tables and need to show them correctly as web pages on demand.
So, which is better for storing large HTML pages, text
or blob
?
I'd use blob
it's a varbinary and does not do any translation. So your html will come out exactly the same way that it went in.
If you want to search and index that html TEXT
may be a better choice.
In that case make sure you use the proper charset.
I'd recommend UTF8.
Seven years have passed since this question was asked. The database industry is converging on using UTF-8 for all text.
If you use TEXT
and make it CHARACTER SET utf8mb4
, and you do likewise for all other text fields (except postal_code, country_code, hex, and a few other that are defined to be ascii), then TEXT
makes sense.
But, there is another consideration. If your HTML is an entire page, it makes good sense to put that in a file, not a database table. That way, it can be fetched directly by HTTP. Similarly images and BLOB
lead to a argument for <img src=...>
where ...
is the url of a .jpg
file.
