BLOBS can be inserted by using the form:
X'x1x2x3..xn'
Where:
x1..xn are two hex-digit representation of data.
eg.
sqlite> select X'48656c6c6f20576f726c6400';
Hello World
sqlite> select quote(X'48656c6c6f20576f726c6400');
X'48656C6C6F20576F726C6400'
You'll have to convert to the hex form yourself, as SQL appears to have no
way to quote NUL bytes within a string.
