用于检索 WooCommerce 订单项目和元数据的 SQL 选择查询答案

【问题标题】：SQL Select Query for Retrieving WooCommerce Order Items and Meta Data用于检索 WooCommerce 订单项目和元数据的 SQL 选择查询

【问题描述】：

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 结构和数据存储位置，但作为 SQL 新手，我被困在最后一道障碍中。

我已经能够使用此参考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订单项视图。有 2 个表存储订单项目的详细信息：

wp_woocommerce_order_items wp_woocommerce_order_itemmeta

我已经能够从 wp_woocommerce_order_items 表中创建基本的记录列表，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

这会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 表中的每个订单项添加额外的列。此表包含每个行项目的多条记录，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

我想将其中的每一个都转换成一个新列，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

我不确定在此处使用哪种 SQL 语法 - 我尝试使用与上述链接类似的语法，但到目前为止还未能使其正常工作，并且不确定这是否确实正确语法。

我设法通过反复试验解决了这个问题。这是最终起作用的查询：

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

谢谢。如何获得带有顶级字段的customer_id 字段？
您需要查询订单本身，其中包含每个订单的 customer_id，因此您将直接查询wp_posts 表
数量为空：/

【解决方案2】：

您可以使用此查询来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'

感谢分享 - 为获取当前正在处理的订单的产品，我们已经在这个问题上摆弄了一段时间！

@mostafa Norzade 我没有评论权限，所以发布为答案

user_id 的 meta_key 是 '_customer_user'，所以只需添加以下内容： max( CASE WHEN pm.meta_key = '_customer_user ' and p.ID = pm.post_id THEN pm.meta_value END ) as customer_user,

它不起作用..你能重写完整的查询吗？
