Description Author

This class can dump MySQL tables in chunks of limited size.

It can query a given MySQL database table to get statistics of its size.

Then the class calls the mysqldump program multiple times to output the SQL INSERT statments to multiple files, each one with a limited number of rows.

Prize: One downloadable copy of PhpED Professional		 One common way to generate backups of a database is to dump to a file a list of SQL statements that can be used later to recreate each database table. That is what the mysqldump does for generating dumps of MySQL databases.

Tables with many records may generate large database dump files.

This class implements a solution to avoid generating database dump files that exceed a given limit in size.

It queries a given MySQL database to get statistics of the size of each database table. Then it runs the mysqldump program as many times as necessary to generate separate database dump files of each database table, so each has a limited number of rows.

This way it assures that each database dump file does not exceed a given size limit.
