如何在SQL Server中读取XML文件包含多个节点

Question

How to read XML having multiple nodes into temporary table in SQL Server. I had done below things but getting wrong output. I want to insert all below xml data into single table

updating Question as suggested by @Larnu : There are only 2 Bol_reference, so my query should return 2 rows but when i am including notify tag, rows affected is 4 which is wrong

Below is the XML String,

set @DocumentControlXML = '<Awbolds>
<Master_bol>
<Customs_office_code>SECMB</Customs_office_code>
<Voyage_number>091</Voyage_number>

SQL QUERY - Below is my SQL Query

select distinct
        o.value('Bol_reference[1]','NVARCHAR(100)') AS Bol_reference,
        o.value('Line_number[1]','NVARCHAR(100)') AS Line_number,
        o.value('Bol_nature[1]','NVARCHAR(100)') AS Bol_nature,
        o.value('Bol_type_code[1]','NVARCHAR(100)') AS Bol_type_code,
        o.value('Master_bol_ref_number[1]','NVARCHAR(100)') AS Master_bol_ref_number,
        o.value('Unique_carrier_reference[1]','NVARCHAR(100)') AS Unique_carrier_reference,
        c.value('Consolidated_Cargo[1]','NVARCHAR(100)') AS Consolidated_Cargo,
        d.value('Place_of_loading_code[1]','NVARCHAR(100)') AS Place_of_loading_code,
        d.value('Place_of_unloading_code[1]','NVARCHAR(100)') AS Place_of_unloading_code,
        e.value('Carrier_code[1]','NVARCHAR(100)') AS Carrier_code_c,
        e.value('Carrier_name[1]','NVARCHAR(100)') AS Carrier_name_c,

        f.value('Notify_code[1]','NVARCHAR(100)') AS Notify_code,
        f.value('Notify_name[1]','NVARCHAR(100)') AS Notify_name,
        f.value('Notify_address[1]','NVARCHAR(100)') AS Notify_address

FROM @DocumentControlXML.nodes('Awbolds/Bol_segment/Bol_id') v(o)
OUTER APPLY o.nodes('/Awbolds/Bol_segment') b(c)
OUTER APPLY o.nodes('/Awbolds/Bol_segment/Load_unload_place') c(d)
OUTER APPLY o.nodes('/Awbolds/Bol_segment/Traders_segment/Carrier') d(e)
OUTER APPLY o.nodes('//Bol_segment/Traders_segment/Notify') e(f)

Please see below screen shot output Output : when i include Notify tag --> This is wrong, It should return 2 Records

Output : when i don't include Notify tag This is correct

Answer 1

Your approach tries to follow the right track, but is to complicated:

select  @DocumentControlXML.value('(/Awbolds/Master_bol/Customs_office_code/text())[1]','nvarchar(15)') AS Master_Custom_office_code,
        --add all master-properties with direct calls to .value()
        seg.value('(Bol_id/Bol_reference/text())[1]','NVARCHAR(100)') AS Bol_reference,
        seg.value('(Bol_id/Line_number/text())[1]','NVARCHAR(100)') AS Line_number,
        --add all other values from Bol_id
        seg.value('(Consolidated_Cargo/text())[1]','NVARCHAR(100)') AS Consolidated_Cargo,
        seg.value('(Load_unload_place/Place_of_loading_code/text())[1]','NVARCHAR(100)') AS Place_of_loading_code,
        --add all other values from loading places
        seg.value('(Traders_segment/Carrier/Carrier_code/text())[1]','NVARCHAR(100)') AS Carrier_code_c,
        --and more values from within the carrier
        seg.value('(Traders_segment/Exporter/Exporter_name/text())[1]','NVARCHAR(100)') AS Exporter_name_c,
        --similiar with <Notify> and <Consignee>
        seg.value('(ctn_segment/Ctn_reference/text())[1]','NVARCHAR(100)') AS Ctn_reference
        --same with all values here and also for the other elements like <Goods_segment>, <Value_segment>
FROM @DocumentControlXML.nodes('Awbolds/Bol_segment') A(seg);

The idea in short (and some remarks about your own code:

We need the APPLY SomeXml.nodes() for repeating elements only. Therefore we can read the 1:1 values in <Master_bol> directly from the document, but we need .nodes() to get a derived table of the repeating <Bol_segment> elements.

With the XML provided in your question we get two XML fragments, each representing one <Bol_segment> . The values within such a segment look like beeing 1:1 within their path. Might be, that there are multiple Carriers, Exporters what ever... In this case you would need a nested .nodes() to get the repeating values within a fragment.

In general it is a good idea to add /text() . This will make the reading faster.

UPDATE

You commented, that your XML contains repeated <ctn_segment> within your second <Bol_segment> . This is a case for a nested nodes() :

select  @DocumentControlXML.value('(/Awbolds/Master_bol/Customs_office_code/text())[1]','nvarchar(15)') AS Master_Custom_office_code,
        --add all master-properties with direct calls to .value()
        seg.value('(Bol_id/Bol_reference/text())[1]','NVARCHAR(100)') AS Bol_reference,
        seg.value('(Bol_id/Line_number/text())[1]','NVARCHAR(100)') AS Line_number,
        --add all other values from Bol_id
        seg.value('(Consolidated_Cargo/text())[1]','NVARCHAR(100)') AS Consolidated_Cargo,
        seg.value('(Load_unload_place/Place_of_loading_code/text())[1]','NVARCHAR(100)') AS Place_of_loading_code,
        --add all other values from loading places
        seg.value('(Traders_segment/Carrier/Carrier_code/text())[1]','NVARCHAR(100)') AS Carrier_code_c,
        --and more values from within the carrier
        seg.value('(Traders_segment/Exporter/Exporter_name/text())[1]','NVARCHAR(100)') AS Exporter_name_c,
        --similiar with <Notify> and <Consignee>
        ctn.value('(Ctn_reference/text())[1]','NVARCHAR(100)') AS Ctn_reference
        --same with all values here and also for the other elements like <Goods_segment>, <Value_segment>
FROM @DocumentControlXML.nodes('Awbolds/Bol_segment') A(seg)
OUTER APPLY A.seg.nodes('ctn_segment') B(ctn);

Answer 2

I had change my query like below.

select distinct

        o.value('Bol_reference[1]','NVARCHAR(100)') AS Bol_reference,
        o.value('Line_number[1]','NVARCHAR(100)') AS Line_number,
        o.value('Bol_nature[1]','NVARCHAR(100)') AS Bol_nature,
        o.value('Bol_type_code[1]','NVARCHAR(100)') AS Bol_type_code,
        o.value('Master_bol_ref_number[1]','NVARCHAR(100)') AS Master_bol_ref_number,
        o.value('Unique_carrier_reference[1]','NVARCHAR(100)') AS Unique_carrier_reference,
        c.value('Consolidated_Cargo[1]','NVARCHAR(100)') AS Consolidated_Cargo,
