Remarks
Return the length of the column value in the result row. Column indices start at 0. This returns 0 for a null and number of bytes for text or blob. Numeric values are converted to a string and the length of the string is returned. See the sqlite documentation for details. Note that this cannot be used to distinguish a null value from an empty text or blob. Note that this returns the number of bytes in the text value, not the number of characters.
