Question

我想生成csv文件。下面的代码创建了csv文件，但是无法为每个新行追加数据行。

我错过了什么吗？

以下是代码：

xquery version "1.0-ml";
let $filename := "D:\csv-reports\test.csv"

let $directory-query := cts:directory-query("/searcdoc/")
let $uris := cts:uris((), (), $directory-query)

for $uri in $uris
let $additional := doc($uri)/searcdoc/access/additional/text()
let $des := doc($uri)/searcdoc/std/text()
let $option := <options xmlns="xdmp:save"><method>text</method></options>
let $results := text{((fn:string-join(($uri, $des, $additional), ",")), "&#10;")}

return

xdmp:save($filename, $results, $option)

我认为你只需要重新安排一下代码。试试这个：

xquery version "1.0-ml";
let $filename := "D:\csv-reports\test.csv"

let $directory-query := cts:directory-query("/searcdoc/")
let $option := <options xmlns="xdmp:save"><method>text</method></options>
let $uris := cts:uris((), (), $directory-query)
let $lines := 
  for $uri in $uris
  let $additional := doc($uri)/searcdoc/access/additional/text()
  let $des := doc($uri)/searcdoc/std/text()
  return fn:string-join(($uri, $des, $additional), ",")

return
  xdmp:save($filename, text{ fn:string-join($lines, "&#10;") }, $option)

已修改，可将"\n"更改为"
"

如何使用xdmp：save在csv文件中保存MarkLogic数据
