Sitecore查询语言：更新+；哪里

我正试图通过Sitecore Rocks查询分析器使用Sitecore查询语言，在保持当前状态的同时，将一组项目更新为新的工作流。我现在有：

update set @#__Workflow state# = "--GUID of the workflow state--" from //*[@@id='--GUID of the parent Item--']/*

这很有效。我想做的是，包括where语句，这样我就可以在切换工作流的同时保持草稿/等待批准/批准状态

update set @#__Workflow state# = "--GUID of the DRAFT workflow state--" from //*[@@id='--GUID of the parent Item--']/* where @#__Workflow state# = "--GUID of the original DRAFT workflow state--";
update set @#__Workflow state# = "--GUID of the APPROVED workflow state--" from //*[@@id='--GUID of the parent Item--']/* where @#__Workflow state# = "--GUID of the original APPROVED workflow state--";

然而，这不起作用。我的where子句是否存在语法问题，或者where不能与Sitecore查询语言中的更新一起使用。

在查询语言中，“where子句”不起作用

您应该使用/*[@fieldName=“value”]来选择项目，如下所示：

update set @#__Workflow state# = "--GUID of the DRAFT workflow state--" from //*[@@id='--GUID of the parent Item--']/*[@#__Workflow state# = "--GUID of the original DRAFT workflow state--"];

update set @#__Workflow state# = "--GUID of the APPROVED workflow state--" from //*[@@id='--GUID of the parent Item--']/*[@#__Workflow state# = "--GUID of the original APPROVED workflow state--"];
