EXAMPLES

LONGBLOB

Example of LONGBLOB:

CREATE TABLE longblob_example (
   description VARCHAR(20),
   example LONGBLOB
) DEFAULT CHARSET=latin1; -- One byte per char makes the examples clearer

Note that the maximum size of a LONGBLOB is so large that it cannot be sent to the server without breaking the value up into chunks (something that the command-line client cannot do). For values larger than 16M you can increase the max_allowed_packet size up to a maximum of 1024M to increase the allowed size of non-chunked values.

INSERT INTO longblob_example VALUES
   ('Normal foo', 'foo'),
   ('Trailing spaces foo', 'foo      '),
   ('NULLed', NULL),
   ('Empty', ''),
   ('Maximum', RPAD('', 4294967295, CHAR(7)));
ERROR 1301 (HY000): Result of rpad() was larger than max_allowed_packet (16777216) - truncated

Data Too Long

When SQL_MODE is strict (the default) a value is considered "too long" when its length exceeds the size of the data type, and an error is generated.

Example of data too long behavior for LONGBLOB:

TRUNCATE longblob_example;

INSERT INTO longblob_example VALUES
   ('Overflow', RPAD('', 4294967296, CHAR(7)));
ERROR 1301 (HY000): Result of rpad() was larger than max_allowed_packet (16777216) - truncated
