SQL选择查询检索WooCommerce订单项目和元数据

Question

我正在为我的Wordpress数据库创建一些SQL视图，以便更轻松地查看通过WooCommerce插件生成的在线订单。我熟悉WooCommerce的结构和数据的存储位置，但作为一名SQL新手，我在最后一个障碍上遇到了困难。

我已经能够使用此引用创建所有订单详细信息的第一个视图：

http://codecharismatic.com/sql-script-to-get-all-woocommerce-orders-including-metadata/

现在，我需要为每个订单创建一个类似的行项目视图。有两个表存储订单项目详细信息：

wp_woocommerce_order_itemswp_woocommerce_order_itemmeta

我已经能够从wp_商业_订单_项目表中创建记录的基本列表，如下所示：

SELECT order_item_id,order_item_name,order_item_type,order_id
FROM ocm_woocommerce_order_items 
ORDER BY order_id

这将返回一个很好的记录列表，如下所示：

order_item_id   order_item_name order_item_type order_id
 2  Widgets line_item   9
 3  Widgets line_item   10
 4  Widgets line_item   11
 5  Woo Logo    line_item   473
 6  Woo Logo    line_item   473

我现在想为wp_woocommerce_order_itemmeta表中的每个行项添加额外的列。此表包含每个行项的多个记录，如下所示：

 meta_id    order_item_id   meta_key    meta_value
 136    16  _qty    4
 137    16  _tax_class  
 138    16  _product_id 87
 139    16  _variation_id   0
 140    16  _line_subtotal  36
 141    16  _line_total 36
 142    16  _line_subtotal_tax  3.6
 143    16  _line_tax   3.6

我想把这些转换成一个新的列，这样我的输出将包括：

 order_item_id, order_item_name, order_item_type, order_id, qty, tax_class, product_id, variation_id, line_subtotal, line_total, line_subtotal_tax, line_tax

我不确定在这里使用哪种SQL语法——我尝试过使用与上面链接类似的语法，但到目前为止还无法使其正常工作，也不确定这是否是正确的语法。

Answer 1

@mostafa Norzade我没有评论所以张贴作为答案

用户id的meta_键是“_customer_user”，因此只需添加以下内容：max（当pm.meta_键=“_customer_user”和p.id=pm.post_id，然后是pm.meta_值END）作为customer_user，

您可以使用此查询获取所有已完成的订单，包括所有元数据。

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 p 
        join wp_postmeta pm on p.ID = pm.post_id
        join wp_woocommerce_order_items oi on p.ID = oi.order_id
    WHERE
        post_type = 'shop_order' and
        post_date BETWEEN '2021-07-01' AND '2021-08-01' and
        post_status = 'wc-completed'
    group by
        p.ID

我设法通过反复试验解决了这个问题。以下是最终有效的查询：

select
p.order_id,
p.order_item_id,
p.order_item_name,
p.order_item_type,
max( CASE WHEN pm.meta_key = '_product_id' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as productID,
max( CASE WHEN pm.meta_key = '_qty' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as Qty,
max( CASE WHEN pm.meta_key = '_variation_id' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as variationID,
max( CASE WHEN pm.meta_key = '_line_total' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as lineTotal,
max( CASE WHEN pm.meta_key = '_line_subtotal_tax' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as subTotalTax,
max( CASE WHEN pm.meta_key = '_line_tax' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as Tax,
max( CASE WHEN pm.meta_key = '_tax_class' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as taxClass,
max( CASE WHEN pm.meta_key = '_line_subtotal' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as subtotal
from
ocm_woocommerce_order_items as p,
ocm_woocommerce_order_itemmeta as pm
 where order_item_type = 'line_item' and
 p.order_item_id = pm.order_item_id
 group by
p.order_item_id
