WooCommerce - SQL Query

I need to output product data from SQL to a CSV file. I have created an example file showing the fields that need to be exported. I have marked the cells on the spreadsheet, to show where the data needs to come from. Green = wp_posts Yellow = wp_postmeta Red = wp_woocommerce_order_items The Task: • Write SQL query in PHP that prints data on the screen in table format • JOIN data on [login to view URL], wp_postmeta.post_id, wp_woocommerce_order_items.order_id • Add an export to CSV button that downloads the table of data • Data from "wp_woocommerce_order_items" if "order_item_type" is equal to "line_item" then print the value from the column "order_item_name". If there is more than one item, each item should be printed in a new column. • Data from "wp_posts", print all columns • Data from "wp_postmeta", print the value from "meta_value" for all "meta_key" shown in the example excel file. • Must be complete by 17:00 (Dubai time) Monday 16th November 2015
