使用typo3扩展通量9.0.1更新colPos [英] Update colPos with typo3 extension flux 9.0.1

问题描述

由于更新流量为9.0.1，所以我需要更新元素的colPos.

Since the update flux to 9.0.1 I need to update the colPos of elements.

这很好:

UPDATE `tt_content` 
SET colPos = ((tx_flux_parent * 100) + 11) 
WHERE tx_flux_column = "content";

但是我还需要更新本地化的内容元素.它在tx_flux_parent中具有本地化的父uid.但是我需要标准语言的父uid.

But I need also to update the localized content elements. It have in tx_flux_parent the localized parent uid. But I need the parent uid of the standard language.

我需要通过l18n_parent在tt_content中获取值"tx_flux_parent". 因此，我正在尝试使用l18n_parent建立一个查询，如下所示:

I need to get the value "tx_flux_parent" in tt_content by l18n_parent. So I'm trying to build a query with l18n_parent like this:

UPDATE `tt_content` as t1 
SET colPos = (( (SELECT t2.tx_flux_parent 
                 FROM tt_content t2 
                 WHERE t1.l18n_parent = t2.uid) * 100) + 11) 
WHERE t1.tx_flux_column = "content";

得到这个:

MySQL融合:Dokumentation 1093-表't1'被指定了两次，两者 作为"UPDATE"的目标，并作为数据的单独来源

MySQL meldet: Dokumentation 1093 - Table 't1' is specified twice, both as a target for 'UPDATE' and as a separate source for data

推荐答案

MySQL不允许在另一个子查询中再次引用表正在更新，除非除非它位于FROM子句(派生表).

MySQL does not allow referencing the table being updated again in another subquery, unless it is inside the FROM clause (Derived Table).

但是，在这种情况下，您可以使用自加入":

However, in this particular case, you can rather use "Self-Join":

UPDATE `tt_content` as t1 
JOIN `tt_content` as t2 
  ON t1.l18n_parent = t2.uid 
SET t1.colPos = ((t2.tx_flux_parent * 100) + 11) 
WHERE t1.tx_flux_column = 'content'
