Css 如何从主脚本向Xquery模块提供全局变量？

目前，我通过一个外部变量将两个数据库的名称输入到我的主xql文件中。我想将这些值传递给我的任何XQL模块

例如，我可以有一个主脚本导入模块“mylib”

然后我向主脚本提供dbName外部变量，它可以工作，但我想以某种方式将它传递给我的模块

     module namespace mylib = "http://example.org/mylib";

     declare variable $mylib:dbName external;

     declare function mymod:print() as xs:string  {
         $mymod:dbName
     };

如何将本地dbName的值绑定到模块的实例$myLib:dbName

我试过：

• 将主文件中的变量设置为全局变量，以便任何导入的模块都可以读取这些变量
• 在模块中声明相同的变量，并尝试使用类似于声明变量$mylib:dbname:=$dbname的内容从主类分配它们
• 将模块变量唯一地声明为外部变量，在我的主脚本中从它们获取值，然后尝试从那里读取它

有什么简单的解决办法吗？？或者我必须静态地为任何模块定义相同的值吗？

为什么不将其作为参数传递给函数

mymod:print($dbname)

为什么不把它作为参数传递给函数呢

mymod:print($dbname)

如果XQuery处理器允许部分应用程序使用参数占位符，则可以在映射中返回一组方法，这些方法已绑定了

$dbname

参数

示例模块

xquery version "3.1";

module namespace mymod = "http://example.org/mymod";

declare function mymod:print ($dbname as xs:string) as xs:string  {
    $dbname
};

declare function mymod:items-by-name ($dbname as xs:string, $names as xs:string*) as xs:string  {
    collection($dbname)//item[@name = $names]
};

declare function mymod:get-bound-methods ($dbname as xs:string) as map(*) {
    map {
        (: return result of a function :)
        "print": mymod:print($dbname),
        (: return partially applied function:)
        "items-by-name": mymod:items-by-name($dbname, ?) 
    }
};

import module namespace mymod = "http://example.org/mymod" at "mymod.xqm";

declare variable $dbName external; 

declare variable $local:bound := mymod:get-bound-methods($dbName);

(: print evaluates to a xs:string :)
$local:bound?print,
(: items-by-name evaluates to a function with an arity of 1 :)
$local:bound?items-by-name("a"),
$local:bound?items-by-name(("a", "sequence", "of", "names"))

用法

xquery version "3.1";

module namespace mymod = "http://example.org/mymod";

declare function mymod:print ($dbname as xs:string) as xs:string  {
    $dbname
};

declare function mymod:items-by-name ($dbname as xs:string, $names as xs:string*) as xs:string  {
    collection($dbname)//item[@name = $names]
};

declare function mymod:get-bound-methods ($dbname as xs:string) as map(*) {
    map {
        (: return result of a function :)
        "print": mymod:print($dbname),
        (: return partially applied function:)
        "items-by-name": mymod:items-by-name($dbname, ?) 
    }
};

import module namespace mymod = "http://example.org/mymod" at "mymod.xqm";

declare variable $dbName external; 

declare variable $local:bound := mymod:get-bound-methods($dbName);

(: print evaluates to a xs:string :)
$local:bound?print,
(: items-by-name evaluates to a function with an arity of 1 :)
$local:bound?items-by-name("a"),
$local:bound?items-by-name(("a", "sequence", "of", "names"))

因为我必须把它传给所有的Methods，我想知道是否有一个easz-waz，特别是如果我想要一些类似内部静态变量的Szncroniyation，因为我必须把它传给所有Methods，我想知道是否有一个easz-waz，特别是，如果我想要一些带有内部静态变量的szncroniyation，我也有类似的问题：我想将一个外部变量（称为“x”）从主模块传递到子模块。子模块使用此外部变量（“x”）构建全局变量，因此我无法将值（“x”）作为参数发送。这是一种方法吗？Xquery没有真正的全局变量。它们总是本地的。但如果这对于您的用例来说已经足够了，您可以修改
