Description:
On Solaris platform, if one tries to log current process info in a trigger, this error pops.

my.cnf related variables :
default-character-set=utf8
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

Clients are 
- mysql command line client on localhost
- MySQL Query browser on a remote Windows machine

How to repeat:
DROP TABLE IF EXISTS `test`.`dbgproc`;
CREATE TABLE  `test`.`dbgproc` (
  `LBL` varchar(32) NOT NULL DEFAULT '',
  `UPDDT` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  `ID` bigint(4) NOT NULL DEFAULT '0',
  `USER` varchar(16) NOT NULL DEFAULT '',
  `HOST` varchar(64) NOT NULL DEFAULT '',
  `DB` varchar(64) DEFAULT NULL,
  `COMMAND` varchar(16) NOT NULL DEFAULT '',
  `TIME` bigint(7) NOT NULL DEFAULT '0',
  `STATE` varchar(64) DEFAULT NULL,
  PRIMARY KEY (`LBL`)
) ENGINE=MEMORY DEFAULT CHARSET=utf8;

DROP TABLE IF EXISTS `test`.`a`;
CREATE TABLE  `test`.`a` (
  `ID` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `VL` int(10) unsigned NOT NULL,
  `X` int(10) unsigned NOT NULL,
  PRIMARY KEY (`ID`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

delimiter $$

DROP TRIGGER IF EXISTS test.`a_AFTER_INSERT` $$
CREATE TRIGGER test.`a_AFTER_INSERT` AFTER INSERT ON test.`a`
  FOR EACH ROW
    REPLACE dbgproc SELECT  'test.a' AS LBL,  NOW(),  A.`ID`,  A.`USER`,  A.`HOST`,  A.`DB`,  A.`COMMAND`,  A.`TIME`,  A.`STATE`
    FROM information_schema.`PROCESSLIST` A WHERE A.`ID` = CONNECTION_ID();
$$

delimiter ;

INSERT INTO test.a VALUES (NULL, 2, 2);

Strangely, error pops even STATE field is not refenced. E.g. try " '' AS `STATE`" instead of " A.`STATE` ".

Besides REPLACE, CREATE ... SELECT cause the same error.

Work around is first storing into user variables :
delimiter $$
DROP TRIGGER IF EXISTS test.`a_AFTER_INSERT` $$
CREATE TRIGGER test.`a_AFTER_INSERT` AFTER INSERT ON test.`a`
  FOR EACH ROW
  BEGIN
  SELECT  A.`ID`, A.`USER`, A.`HOST`, A.`DB`, A.`COMMAND`, A.`TIME`, A.`STATE`
    INTO @ID, @USER, @HOST, @DB, @COMMAND, @TIME, @STATE
    FROM information_schema.`PROCESSLIST` A WHERE A.`ID` = CONNECTION_ID();
  REPLACE dbgproc SELECT 'test.a' AS LBL, NOW(),
    @ID, @USER, @HOST, @DB, @COMMAND, @TIME, @STATE;
  END;
$$
delimiter ;

Note: This bug is not repeatable in windows platform.

Thank you for the report.

I can not repeat this error on Solaris platform. Please paste exact error message you get and indicate hardware (SPARC or x86) you run Solaris on.

Solaris hardware is X86.

Thank you for the feedback.

Could you also send output of SELECT * FROM information_schema.`PROCESSLIST` where id=CONNECTION_ID();, so we can be sure there is nothing unusual in it.

Here is the strange version where there is no explicit reference to column STATE :

Thank you for the report.

Verified as described with version 6.0. With version 5.1 bug is not repeatable for me.

Cause is replication. Strange if replace --source include/master-slave.inc with --source include/have_log_bin.inc in the test file error is not repeatable.

I'm having the same problem with importing a csv file. It has an error on a column I'm trying to import. If I remove that column, then it picks another column. But, I don't see what the problem is. Here is my code. The error is at the very end after I created the table and imported the csv file (ERROR 1366 (HY000): Incorrect integer value: '' for column 'listID' at row 1). Any help with this would be much appreciated. I'm a graphic designer trying to learn this and I'm running out of time.
