This MySQL statement has been deprecated and will be removed from future releases of MySQL.


Below is the syntax for this command. Text within square brackets (i.e, [ and ] ) are optional. Choices are separated by bars (i.e, | ). Ellipses preceded by a comma indicates a repeating pattern. Ellipses before or after syntax are used to highlight a relevant except from the larger syntax. Text displayed in italic letters represent text that should be replaced with the specific names related to the database (e.g., column with the name of the column).



This statement has been deprecated and will be removed from future releases of MySQL. It never worked very well. It was meant to make a copy of all the databases on the master server (except the mysql database) and copy them to the slave servers. It gets a global read lock on all tables while it takes a snapshot of the databases, and releases the lock before copying them to the slaves. The MASTER_LOG_FILE and the MASTER_LOG_POS variables will be updated so that the slave knows where to begin logging.

This statement works only with MyISAM tables. The user for the connection must have RELOAD, SELECT, and SUPER privileges on the master server. The user must also have CREATE and DROP privileges on the slave server. For large databases, increase the values of the net_read_timeout and net_write_timeout variables with the SET statement. To load a specific table from the master server, use the LOAD TABLE...FROM MASTER statement.

Again, this statement does not work very well: it's not dependable and usually has problems with properly copying data from the master to the slave. Instead, use a utility such as mysqldump to copy the data on the master and then transfer the resulting file to the slave, as described in detail in my tutorial article on Backing Up MySQL.
