Question

我想用售价价格替换我的WooCommerce商店的所有常规价格，并删除 wp_postmeta 表格下的促销价格值。

post_id 列对于每种产品的价格都相同，而要复制的列 _sale_price 为 {{1 <}> 并删除 _price 。

我可以运行什么查询来实现此目的？

Answer 1

这是您正在寻找的纯MySQL查询：

首先，您必须使用自我加入来更新 _price 和 _regular_price 字段

UPDATE `wp_postmeta` AS a,
       `wp_postmeta` AS b
SET a.`meta_value` = b.meta_value
WHERE a.post_id = b.post_id
  AND a.meta_key IN ('_price', '_regular_price')
  AND b.meta_key = '_sale_price'
  AND b.meta_value != ''
  AND a.`post_id` IN
    (SELECT `ID`
     FROM `wp_posts`
     WHERE `post_type` = 'product'
       AND `post_status` = 'publish');

现在要重置销售价格和日期，您必须将其设置为空白

UPDATE `wp_postmeta`
SET `meta_value` = ''
WHERE `meta_key` IN ('_sale_price', '_sale_price_dates_from', '_sale_price_dates_to')
  AND `post_id` IN
    (SELECT `ID`
     FROM `wp_posts`
     WHERE `post_type` = 'product'
       AND `post_status` = 'publish' );

如果要删除此字段，请使用带有WHERE子句的DELETE语句，它将解决您的目的。

此外，您还必须删除存储在wp_options表格中的 _transient_timeout_wc_var_prices_{{post_id}} 和_transient_wc_var_prices_{{post_id}} 下的WooCommerce产品价格缓存{1}}

option_name

特别感谢@LoicTheAztec指出产品价格缓存

以上查询已经过测试并为我工作。

在运行此查询之前，请先进行数据库备份

希望这有帮助！

这是一个自定义功能，将销售价格复制到正常价格，并将重置销售价格。在WooCommerce中有价格：

有效价格：Traceback (most recent call last): File "C:\Program Files\Python36\lib\site-packages\pandas\core\indexes\base.py", line 2442, in get_loc return self._engine.get_loc(key) File "pandas\_libs\index.pyx", line 132, in pandas._libs.index.IndexEngine.get_loc (pandas\_libs\index.c:5280) File "pandas\_libs\index.pyx", line 154, in pandas._libs.index.IndexEngine.get_loc (pandas\_libs\index.c:5126) File "pandas\_libs\hashtable_class_helper.pxi", line 1210, in pandas._libs.hashtable.PyObjectHashTable.get_item (pandas\_libs\hashtable.c:20523) File "pandas\_libs\hashtable_class_helper.pxi", line 1218, in pandas._libs.hashtable.PyObjectHashTable.get_item (pandas\_libs\hashtable.c:20477) KeyError: 'C' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "C:\Users\Development\workspace\TestPython\TestPython.py", line 6, in <module> df['C'] = np.where(df['A'] > df['C'].shift(), df['B'].shift(), df['A']) File "C:\Program Files\Python36\lib\site-packages\pandas\core\frame.py", line 1964, in __getitem__ return self._getitem_column(key) File "C:\Program Files\Python36\lib\site-packages\pandas\core\frame.py", line 1971, in _getitem_column return self._get_item_cache(key) File "C:\Program Files\Python36\lib\site-packages\pandas\core\generic.py", line 1645, in _get_item_cache values = self._data.get(item) File "C:\Program Files\Python36\lib\site-packages\pandas\core\internals.py", line 3590, in get loc = self.items.get_loc(item) File "C:\Program Files\Python36\lib\site-packages\pandas\core\indexes\base.py", line 2444, in get_loc return self._engine.get_loc(self._maybe_cast_indexer(key)) File "pandas\_libs\index.pyx", line 132, in pandas._libs.index.IndexEngine.get_loc (pandas\_libs\index.c:5280) File "pandas\_libs\index.pyx", line 154, in pandas._libs.index.IndexEngine.get_loc (pandas\_libs\index.c:5126) File "pandas\_libs\hashtable_class_helper.pxi", line 1210, in pandas._libs.hashtable.PyObjectHashTable.get_item (pandas\_libs\hashtable.c:20523) File "pandas\_libs\hashtable_class_helper.pxi", line 1218, in pandas._libs.hashtable.PyObjectHashTable.get_item (pandas\_libs\hashtable.c:20477) KeyError: 'C'
常规价格：'_price'
促销价格：'_regular_price'

因此您需要更新常规价格并重置销售价格的所有相关数据。您还需要刷新价格此功能的用户界面将显示在商店页面或单个产品页面仅适用于管理员和商店经理。
