Bug Description
I am getting a parse column error on two different tests I've tried. I'm running percona-playback on Ubuntu 10.0.4 and have tried both Percona 5.5 and MySQL 5.1 servers, getting the same results.
The queries run for the first test:
SELECT * FROM test LIMIT 10;
UPDATE test SET p = "test" WHERE id = 1;
DELETE FROM test WHERE id = 2;
The second test was meant to capture a sysbench oltp test.
Printing out the queries causing the errors gave me the following results:
(First test) select @@version_coort
(Second test) SHOW TABLE STATUS Lort
It seems like this may be a parsing issue with the tcpdump file? I'm guessing it should be select @@version_(comment, compile_machine, or compile_os) and SHOW TABLE STATUS LIKE <something>, but not sure why it's getting "ort" instead.
