When creating and saving queries with MX Query Builder, the application needs a place to store your settings, queries, and database table relations. By saving your settings, each time MX Query Builder is opened it will already have the queries and database diagram set as you left them.
There are three extra tables added to your current database:
qub3_queries_que - the queries table stores info for each saved query: the name, SQL code, and information on which field.
qub3_relations_rel - the relations table stores information regarding your table relationships set up in the database diagram.
qub3_settings_set - the settings table stores the general MX Query Builder settings chosen in the Query Menu -> Settings option.
Note: To keep MX
Query Builder running smoothly, it is best not to edit the contents
of these tables.
