What should I use to save a long topic ?

How to&Answers:

BLOBs are for Binary Large Objects. If you’re storing binary data in your DB, then BLOB would be the table type you want. Otherwise.. longtext.

In your case longtext.

Answer:

BLOB and TEXT are basically identical, except that TEXT fields have character set translation rules applied. BLOB fields do not. So with BLOB what you put in is what you get. With TEXT, what you put may not be what you get out.

Answer:

You can use collation & character sets on TEXT columns, which would mean that:

  1. If you specify a different charset for a connection than the TEXT column is (for instance,latin1 column, utf-8 requested), MySQL will convert the contents to the required charset.
  2. You can sort & compare TEXT columns based on collation.

BLOB‘s are just ‘binary sequences’, and you’ll get them ‘as is’.
