Each value stored in an SQLite database (or manipulated by the database engine) has one of the following storage classes:

NULL. The value is a NULL value.

INTEGER. The value is a signed integer, stored in 1, 2, 3, 4, 6, or 8 bytes depending on the magnitude of the value.

REAL. The value is a floating point value, stored as an 8-byte IEEE floating point number.

TEXT. The value is a text string, stored using the database encoding (UTF-8, UTF-16BE or UTF-16LE).

BLOB. The value is a blob of data, stored exactly as it was input.

That implies that SQLite performs some manipulation (encoding and/or decoding) upon fields designated as TEXT.

Storable stores integers in binary, which means that some value, or some subset of the bytes making up that value might look like some unicode entity that is illegal or has some special meaning (like Byte Order Mark: 0xFFFE or 0xFEFF), that would cause the round trip into and out of the DB to change the content some how.

I'd be very much inclined to using BLOB for Storable data.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
