iteration af XML-data i sql server 2005

Forudsat at din eksempel-XML ser sådan ud:

<MissingDS>
  <MissingTable>
    <MissingColumn>abc</MissingColumn>
    <TableName>tblMyTable</TableName>
    <PhysicalColName>table_abc</PhysicalColName>
    <Grantor_Grantee>nobody</Grantor_Grantee>
  </MissingTable>
  <MissingTable>
    <MissingColumn>xyu</MissingColumn>
    <TableName>tblMyTable2</TableName>
    <PhysicalColName>table_xyz</PhysicalColName>
    <Grantor_Grantee>nobody2</Grantor_Grantee>
  </MissingTable>
</MissingDS>

Så kunne du parse dette med den nye SQL Server 2005 XQuery-understøttelse som denne:

DECLARE @MissingXML XML
SET @MissingXML = CAST(@MissingRecordsXML AS XML)

SELECT
    Missing.Rec.value('(MissingColumn)[1]', 'varchar(1000)') AS 'MissingColumn',
    Missing.Rec.value('(TableName)[1]', 'varchar(100)') AS 'TableName',
    Missing.Rec.value('(PhysicalColName)[1]', 'varchar(100)') AS 'Physical',
    Missing.Rec.value('(Grantor_Grantee)[1]', 'varchar(100)') AS 'Grantor_Grantee'
FROM
    @MissingXML.nodes('/MissingDS/MissingTable') AS Missing(Rec)

Hvis du kan VÆLGE det, kan du selvfølgelig også INDSÆTTE de samme datarækker i en tabel ganske nemt:

INSERT INTO 
  dbo.MissingDSTable(MissingColumn, TableName, PhysicalColName, Grantor_Grantee)
    SELECT
       Missing.Rec.value('(MissingColumn)[1]', 'varchar(1000)') AS 'MissingColumn',
       Missing.Rec.value('(TableName)[1]', 'varchar(100)') AS 'TableName',
       Missing.Rec.value('(PhysicalColName)[1]', 'varchar(100)') AS 'Physical',
       Missing.Rec.value('(Grantor_Grantee)[1]', 'varchar(100)') AS 'Grantor_Grantee'
    FROM
       @MissingXML.nodes('/MissingDS/MissingTable') AS Missing(Rec)

Håber dette hjælper lidt
