Data from XML to MSSQL using CROSS APPLY

Question

I'm having trouble extracting some data from a XML file to MSSQL DB using CROSS APPLY, here is what I have:

Note: I did read about how to post here but pardon me if I'm still wrong.

XML File:

<?xml version="1.0" encoding="UTF-8" ?>
<ZMPROD01>
   <IDOC BEGIN="1">
      <EDI_DC40 SEGMENT="1">
         <TABNAM>EDI_DC40</TABNAM>
         <DOCNUM>0000003899888135</DOCNUM>
         <CREDAT>20220201</CREDAT>
         <CRETIM>152041</CRETIM>
      </EDI_DC40>
      <ZPROD SEGMENT="1">
         <WERKS>8285</WERKS>
         <LGNUM>0</LGNUM>
         <AUFNR>000915229446</AUFNR>
         <LINENO>RM01PL01</LINENO>
         <CHARG>0006186588</CHARG>
         <START1>20220202</START1>
         <START2>211609</START2>
         <QTY>4166.000</QTY>
         <END1>20220202</END1>
         <END2>240000</END2>
         <MAKTX>579 FUS5 75ML ULTRA SENST GEL</MAKTX>
         <PLN_ORDER>6963701111</PLN_ORDER>
         <Z1PRODI SEGMENT="1">
            <POSNR>000010</POSNR>
            <MATNR>000000000098920665</MATNR>
         </Z1PRODI>
         <Z1PRODI SEGMENT="1">
            <POSNR>000040</POSNR>
            <HRKFT>V010</HRKFT>
         </Z1PRODI>
         <Z1PRODI SEGMENT="1">
            <POSNR>000050</POSNR>
            <MATNR>000000000099396964</MATNR>
         </Z1PRODI>
      </ZPROD>
   </IDOC>
</ZMPROD01>

My SQL query:

INSERT INTO XMLTESTTABLE(PONo, ASP, LOTNo, EntryDate, StartDate, EndDate, GAS, PlannedQty, LineNum, SAPDesc, StartTime, EndTime)
SELECT
   MY_XML.ZPROD.query('AUFNR').value('.', 'VARCHAR(9)'),
   MY_XML.ZPROD.query('CHARG').value('.', 'VARCHAR(8)'),
   MY_XML.ZPROD.query('PLN_ORDER').value('.', 'VARCHAR(10)'),
   MY_XML.ZPROD.query('START1').value('.', 'date'),
   MY_XML.ZPROD.query('START1').value('.', 'date'),
   MY_XML.ZPROD.query('END1').value('.', 'date'),
   MY_XML.ZPROD.query('CHARG').value('.', 'VARCHAR(8)'),
   MY_XML.ZPROD.query('QTY').value('.', 'VARCHAR(9)'),
   MY_XML.ZPROD.query('LINENO').value('.', 'VARCHAR(1)'),
   MY_XML.ZPROD.query('MAKTX').value('.', 'VARCHAR(9)'),
   MY_XML.ZPROD.query('START2').value('.', 'time'),
   MY_XML.ZPROD.query('END2').value('.', 'time')
FROM (SELECT CAST(MY_XML AS xml)
      FROM OPENROWSET(BULK 'C:\Users\PC_user\Documents\Idoc3899888135.xml', SINGLE_BLOB) AS T(MY_XML)) AS T(MY_XML)
      CROSS APPLY MY_XML.nodes('ZMPROD01/ZPROD') AS MY_XML (ZPROD);

The result I get is (0 rows affected). I tried replacing ZMPROD01/ZPROD several times but different errors appeared, at some point complained about being unable to convert to date datatype.

On a separate note how, can I get data from EDI_DC40 as well? Not sure how the CROSS APPLY would look like to look for different places on the document.

Your help is appreciated.

Thanks.

Answer 1

Please try the following solution.

Notable points:

• I adjusted the XPath expression in the .nodes() method.
• No need to use the .query() method.
• text() is added for performance reasons.
• Last two data elements converted into TIME data type.
• As it was already mentioned, the <END2>240000</END2> is not a legit value for the TIME data type.

SQL

--INSERT INTO XMLTESTTABLE(PONo, ASP, LOTNo, EntryDate, StartDate, EndDate, GAS, PlannedQty, LineNum, SAPDesc, StartTime, EndTime)
SELECT ZPROD.value('(AUFNR/text())[1]', 'VARCHAR(9)')
    , ZPROD.value('(CHARG/text())[1]', 'VARCHAR(8)')
    , ZPROD.value('(PLN_ORDER/text())[1]', 'VARCHAR(10)')
    , ZPROD.value('(START1/text())[1]', 'date')
    , ZPROD.value('(START1/text())[1]', 'date')
    , ZPROD.value('(END1/text())[1]', 'date')
    , ZPROD.value('(CHARG/text())[1]', 'VARCHAR(8)')
    , ZPROD.value('(QTY/text())[1]', 'VARCHAR(9)')
    , ZPROD.value('(LINENO/text())[1]', 'VARCHAR(1)')
    , ZPROD.value('(MAKTX/text())[1]', 'VARCHAR(9)')
    , TRY_CAST(STUFF(STUFF(ZPROD.value('(START2/text())[1]', 'CHAR(6)'),3,0,':'),6,0,':') AS TIME)
    , TRY_CAST(STUFF(STUFF(ZPROD.value('(END2/text())[1]', 'CHAR(6)'),3,0,':'),6,0,':') AS TIME)
FROM (SELECT CAST(MY_XML AS xml)
      FROM OPENROWSET(BULK 'e:\Temp\Idoc3899888135.xml', SINGLE_BLOB) AS T(MY_XML)) AS T(MY_XML)
      CROSS APPLY MY_XML.nodes('/ZMPROD01/IDOC/ZPROD') AS MY_XML (ZPROD);
