根据条件从 Marklogic 暂存中删除文档

Question

我们可以根据条件从 markLogic 暂存中删除文档吗？类似于 delete from data-hub-STAGING where name="John"

示例文档如下：

{
    "source": "source1",
    "name": "John",
    "DOB": "1-01-1990",
    "load_date": "2021-10-23 10:23:55"
}

{
    "source": "source2",
    "name": "John",
    "DOB": "1-01-1990",
    "load_date": "2021-10-23 10:23:55"
}

Answer 1

您可以使用cts.uris() with a cts.jsonPropertyValueQuery() to obtain the list of document URIs that have a JSON property named name with the value "John", and then iterate over the list of URIs and call xdmp.documentDelete()

declareUpdate();
for (const uri of cts.uris("", null, cts.jsonPropertyValueQuery("name", "John"))) {
  xdmp.documentDelete(uri);
}

XQuery 中的等价物：

cts:uris("", (), cts:json-property-value-query("name", "John")) ! xdmp:document-delete(.)
