>Description:
I am testing the replication of one database from this host to a slave MySQL
server.
Some of the queries that ALTER a table structure are not replicated to the
slave,
causing a stop of the replication.
I said "some" because while I was troubleshooting my problems I could
successfully
add/change some fields to my tables (this means that the add/change was
replicated)
but other times a similar operation (eg ALTER of a column with the same
definition of
one that I had successfully altered) gave me a failure.
>How-To-Repeat:
I just tested this and had problems:
# ON MASTER
FLUSH MASTER;
# ON SLAVE
FLASH SLAVE;
# ON MASTER
CREATE TABLE `replication_test` (
`f1` TEXT DEFAULT NULL,
`f2` VARCHAR(50) DEFAULT NULL,
`f3` BIGINT DEFAULT '0' NOT NULL AUTO_INCREMENT PRIMARY KEY,
`f4` TIMESTAMP DEFAULT NULL,
`f5` VARCHAR(50) DEFAULT 'Spaghetti, pizza e mandolino' NOT NULL,
INDEX (`f2`)
) TYPE = MYISAM;
INSERT INTO `replication_test` (`f1`, `f2`, `f3`, `f4`, `f5`) VALUES ('record number
one', 'massimo ferrario', '123456789', NULL, 'Spaghetti, pizza e mandolino');
INSERT INTO `replication_test` (`f1`, `f2`, `f3`, `f4`, `f5`) VALUES ('recordn number
two', NULL, '987654321', NULL, 'Pizza margherita');
UPDATE `replication_test` SET `f1` = 'record number two' , `f2` = NULL, `f4` =
NOW('20020717110024') WHERE `f3` = '987654321';
# THIS QUERY IS NOT REPLICATED TO THE SLAVE
ALTER TABLE `eigest_euro`.`replication_test` CHANGE `f5` `f5` TEXT
#
INSERT INTO `replication_test` (`f1`, `f2`, `f3`, `f4`, `f5`) VALUES ('record number
three', 'paolino paperino', NULL, NOW(), 'Spaghetti all\'amatriciana');
NSERT INTO `replication_test` (`f1`, `f2`, `f3`, `f4`, `f5`) VALUES ('record number
four', NULL, NULL, NOW(), '====****====****====
This is a very long string that should fit the text field in the master database but
should be truncated in the varchar(50) field of the slave database.
====****====****====');
