How do I store binary data in a MySQL database?
回答1:
This question is not so straight forward to answer, as it sounds: There are lots of different binary data usage patterns out there, each with their own caveats and pros and cons. Let me try to summarize:
- Short pieces of binary data, such as password hashes, work very well by simply base64-encoding them and storing the resulting string as a VARCHAR
- "Not-quite-binary" data, such as document snipplets with the occasional non-printable can be escaped and sored as a string
- The BLOB datatype allows you to store arbitrary chunks of binary data, but I strongly recommend against using it: Store the data in a file, then store the path to the file in a String type. You gain nothing from storing binary data, that the DB doesn't "understand" in the DB.

I would suggest LONGBLOB for storing files in MySQL.
It all depends on what kind of binary and your appliction.
TINYBLOB - A BLOB column with a maximum length of 255 (28 - 1) characters.
BLOB - A BLOB column with a maximum length of 65,535 (216 - 1) characters.
MEDIUMBLOB - A BLOB column with a maximum length of 16,777,215 (224 - 1) characters.
LONGBLOB - A BLOB column with a maximum length of 4,294,967,295 (232 - 1) characters.

Binary data can be stored in a MySQL database in a BLOB field. A BLOB is a binary large object that can hold a variable amount of data.
