Store a small log file as a blob in sqlite
For me your last line contradicts the subject (blob vs text), so probably I mistook your idea.
But what about making your log file an INSERT statement on the fly?  Then feed that into your desired sqlite database.  I mean something like this:

$ cat test.sql
INSERT INTO test
SELECT 'something
anything';

$ sqlite3 test &lt; test.sql

$ sqlite3 test
SQLite version 3.6.22
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite&gt; SELECT * FROM test;
something
anything
sqlite&gt;
