HI John,
THank you for your purchase.

WordPress and its plugins store the data in a specific MySQL database, usually referred to as “WPDB”. The structure familiar to users, is based on different post types, post custom (meta) fields, and taxonomies; all stored in a collection of MySQL tables. Querying these elements, however might be somewhat of a headache to someone not that familiar with relative database structures and building SQL queries.

wpDataTables has a built-in WPDB query constructor to help those users. It has a graphical user interface which allows a user to pick the post types, custom/meta fields, and taxonomies, and generates a query and a preview. You can modify the query as needed, and create a wpDataTable based on the modified query.

You can take a look in our documentation about Create a MySQL-query-based table by generating a query to WordPress database.

Please note: this tool is not an ultimate query generator. It simply constructs a suggestion of a query. We are constantly working to improve it, but SQL is such a complicated and flexible language that full automation for constructing queries is next to impossible. Consequently, the more complicated the query, the higher is the probability that it will not return exactly what you need. So, you will often need to play around with the resulting query.
