Sql查詢下載woocommerce的訂單報告

Question

請幫助完成此操作。我需要CSV格式下載woocommerce的訂單報告，對於我提出以下查詢：

header('Content-Type: text/csv; charset=utf-8'); 
header('Content-Disposition: attachment; filename=data.csv'); 

// create a file pointer connected to the output stream 
$output = fopen('php://output', 'w'); 
fputcsv($output, array('ID', 'Date', 'Status','Name')); 
$rows = mysql_query('SELECT ID,post_date,post_status,post_name FROM wp_posts WHERE post_date LIKE "%2016-03-30%"'); 

while ($row = mysql_fetch_assoc($rows)) fputcsv($output, $row); 

而這僅僅是一個線索，在這裏我只取後，從表中的數據。

但我需要連接到postmeta和其他表，以便我可以獲得有關訂單的所有信息。
通過在互聯網上搜索我得到下面的代碼，但我不知道如何與我的代碼整合。
看到查詢的人，讓所有的訂單細節：

select 
    p.ID as order_id, 
    p.post_date, 
    max(CASE WHEN pm.meta_key = '_billing_email' and p.ID = pm.post_id THEN pm.meta_value END) as billing_email, 
    max(CASE WHEN pm.meta_key = '_billing_first_name' and p.ID = pm.post_id THEN pm.meta_value END) as _billing_first_name, 
    max(CASE WHEN pm.meta_key = '_billing_last_name' and p.ID = pm.post_id THEN pm.meta_value END) as _billing_last_name, 
    max(CASE WHEN pm.meta_key = '_billing_address_1' and p.ID = pm.post_id THEN pm.meta_value END) as _billing_address_1, 
    max(CASE WHEN pm.meta_key = '_billing_address_2' and p.ID = pm.post_id THEN pm.meta_value END) as _billing_address_2, 
    max(CASE WHEN pm.meta_key = '_billing_city' and p.ID = pm.post_id THEN pm.meta_value END) as _billing_city, 
    max(CASE WHEN pm.meta_key = '_billing_state' and p.ID = pm.post_id THEN pm.meta_value END) as _billing_state, 
    max(CASE WHEN pm.meta_key = '_billing_postcode' and p.ID = pm.post_id THEN pm.meta_value END) as _billing_postcode, 
    max(CASE WHEN pm.meta_key = '_shipping_first_name' and p.ID = pm.post_id THEN pm.meta_value END) as _shipping_first_name, 
    max(CASE WHEN pm.meta_key = '_shipping_last_name' and p.ID = pm.post_id THEN pm.meta_value END) as _shipping_last_name, 
    max(CASE WHEN pm.meta_key = '_shipping_address_1' and p.ID = pm.post_id THEN pm.meta_value END) as _shipping_address_1, 
    max(CASE WHEN pm.meta_key = '_shipping_address_2' and p.ID = pm.post_id THEN pm.meta_value END) as _shipping_address_2, 
    max(CASE WHEN pm.meta_key = '_shipping_city' and p.ID = pm.post_id THEN pm.meta_value END) as _shipping_city, 
    max(CASE WHEN pm.meta_key = '_shipping_state' and p.ID = pm.post_id THEN pm.meta_value END) as _shipping_state, 
    max(CASE WHEN pm.meta_key = '_shipping_postcode' and p.ID = pm.post_id THEN pm.meta_value END) as _shipping_postcode, 
    max(CASE WHEN pm.meta_key = '_order_total' and p.ID = pm.post_id THEN pm.meta_value END) as order_total, 
    max(CASE WHEN pm.meta_key = '_order_tax' and p.ID = pm.post_id THEN pm.meta_value END) as order_tax, 
    max(CASE WHEN pm.meta_key = '_paid_date' and p.ID = pm.post_id THEN pm.meta_value END) as paid_date, 
    (select group_concat(order_item_name separator '|') from wp_woocommerce_order_items where order_id = p.ID) as order_items 
from 
    wp_posts as p, 
    wp_postmeta as pm 
where 
    post_type = 'shop_order' and 
    p.ID = pm.post_id and 
    post_date BETWEEN '2015-01-01' AND '2015-07-08' 
    and post_status = 'wc-completed' 
group by 
    p.ID 

請幫忙完成這一點，或者有沒有什麼好的方法，而不是這個？
我不想使用插件。
目前我有一個插件，但這是工作緩慢，這就是爲什麼我使這個頁面。

請幫忙解決這個問題。

從我自己的blog post，這是SQL從EAV樣式表佈局中提取信息的格式。

$reportQuery = " 
SELECT 
    A.ID as order_id 
, B.meta_value as b_first_name 
, C.meta_value as b_last_name

, F.meta_value as b_country 
, G.meta_value as b_state 
, H.meta_value as b_city 
, I.meta_value as b_postcode 
, J.meta_value as b_user_id 
, K.user_email as b_email 

FROM wp_posts as A 
LEFT JOIN wp_postmeta B 
    ON A.id = B.post_id AND B.meta_key = '_billing_first_name' 

LEFT JOIN wp_postmeta C 
    ON A.id = C.post_id AND C.meta_key = '_billing_last_name' 

LEFT JOIN wp_postmeta D
