Search for value within BLOB column in MySQL

How can I search inside Blob column in MySQL for some value开发者_如何转开发s ? and Is that possible ?

You should be able to search blobs like other text fields:

SELECT * 
FROM tablename 
WHERE blob_field_name LIKE '%value%'

One thing to notice is that search will be case-sensitive!

Anyway, if possible, it's better to use a TEXT field.
