如何在 MarkLogic 的模板文件中插入 xquery 模块

[英]How to insert a xquery module in a Template file in MarkLogic

问题描述

我编写了一个 xquery 来根据某些条件计算我的记录数，并希望将结果作为列值放在模板文档中。

在这种情况下，如何从模板中调用 xquery

下面是 Xquery，它调用集合中的所有文档：GTM2_Shipment 并根据给定条件给出记录计数。

 xquery version "1.0-ml";
fn:count(
   for $x in collection("GTM2_Shipment")
   let $currentdt := fn:current-date()
   let $sixmonthAgo := $currentdt - xs:yearMonthDuration("P6M")
   where ($x/*:Shipment/*:Ancillary/*:QuotePrice/text() != 0) and
   ($x/*:Shipment/*:ASN/*:TrackedItem/*:Consignment/*:ConsignmentHeader/*:CargoSummary/*:TransMode/text() = 'Road')
   and 
   (fn:substring($x/*:Shipment/*:ASN/*:TrackedItem/*:Consignment/*:Bookings/*:CargoBookingHeader/*:BookingCreateDt,0,11) gt
   (format-date($sixmonthAgo, "[Y0001]-[M01]-[D01]")))
   return $x
)

下面的示例模板，我想再添加一个名为 CountByRoad 的列并添加上面的 xquery，它引用相同的集合 -GTM2_Shipment：

xquery version "1.0-ml";
    import module namespace tde = "http://marklogic.com/xdmp/tde" at "/MarkLogic/tde.xqy";

if (xdmp:database-name(xdmp:database()) = "data-hub-final-SCHEMAS")  then          
    let $Custom_Shipment:=

我不认为你可以做你想做的事。

https://docs.marklogic.com/guide/app-dev/TDE#id_71415

出于性能和安全原因，您的路径表达式仅限于 XPath 的一个子集。 有关更多详细信息，请参阅XQuery 和 XSLT 参考指南中的模板驱动提取 (TDE) 。

https://docs.marklogic.com/guide/app-dev/TDE#id_99178

模板支持使用具有有限功能的 XQuery 子集的方言，其中只有一部分功能可用。

方言不支持更复杂的操作，如循环、FLWOR 语句、迭代和 XML 构造。 也不支持属性轴property:: 。
