Yes, that was exactly my question. > In any event, you can use > sqlite3_value_bytes() to find out the length of the text value > returned. That is, however BYTES, not CHARACTERS. Oh, totally missed sqlite3_value_bytes() function. So then my suggestion to Israel that I wanted to write in the first place still stands: to be more generic you should never use strlen() function, use sqlite3_value_bytes() instead.
