SQL Server 2008 R2 Read through XML

Question

I have a SQL query which can return n number of row. Each row has below mentioned XML. I want to read Rate Plan ID & insert into temp table.

<AvailRateUpdateRS xmlns="http://www.expediaconnect.com/EQC/AR/2007/02">
    <Success>
        <Warning code="7022">Inventory date 2016-12-30; Room Type ID 20583; Rate Plan ID 207782211; Inactive Rate Plan Updated Ref=[b44d7e4e-cf66-11e6-950b-e19b2852ebb6] </Warning>
        <Warning code="7022">Inventory date 2016-12-31; Room Type ID 20583; Rate Plan ID 207782211; Inactive Rate Plan Updated Ref=[b44d7e4e-cf66-11e6-950b-e19b2852ebb6] </Warnring>
        <Warning code="7022">Inventory date 2017-01-02; Room Type ID 20583; Rate Plan ID 203619420; Inactive Rate Plan Updated Ref=[b44d7e4e-cf66-11e6-950b-e19b2852ebb6] </Warning>

Thanks in advance.

Answer 1

Ï need to remove the xmlns to Expedia, but in your environment maybe you di not do it.

First, create a function to separate de columns of the warning

Create FUNCTION dbo.Wordparser
(
  @multiwordstring VARCHAR(max),
  @wordnumber      NUMERIC,
  @Separator char(1) 
)
returns VARCHAR(max)
AS
  BEGIN
      DECLARE @remainingstring VARCHAR(max)
      SET @remainingstring=@multiwordstring

      DECLARE @numberofwords NUMERIC
      SET @numberofwords=(LEN(@remainingstring) - LEN(REPLACE(@remainingstring, @Separator, '')) + 1)

      DECLARE @word VARCHAR(max)
      DECLARE @parsedwords TABLE
      (
         line NUMERIC IDENTITY(1, 1),
         word VARCHAR(max)
      )

      WHILE @numberofwords > 1
        BEGIN
            SET @word=LEFT(@remainingstring, CHARINDEX(@Separator, @remainingstring) - 1)

            INSERT INTO @parsedwords(word)
            SELECT @word

            SET @remainingstring= REPLACE(@remainingstring, @word + @Separator, '')
            SET @numberofwords=(LEN(@remainingstring) - LEN(REPLACE(@remainingstring, @Separator, '')) + 1)

            IF @numberofwords = 1
              BREAK

            ELSE
              CONTINUE
        END

      IF @numberofwords = 1
        SELECT @word = @remainingstring
      INSERT INTO @parsedwords(word)
      SELECT @word

      RETURN
        (SELECT RTRIM(LTRIM(word))
         FROM   @parsedwords
         WHERE  line = @wordnumber)

  END

GO

Second, use it:

declare @xml xml = REPLACE('<AvailRateUpdateRS xmlns="http://www.expediaconnect.com/EQC/AR/2007/02">
  <Success>
    <Warning code="7022">Inventory date 2016-12-30; Room Type ID 20583; Rate Plan ID 207782211; Inactive Rate Plan Updated Ref=[b44d7e4e-cf66-11e6-950b-e19b2852ebb6] </Warning>
    <Warning code="7022">Inventory date 2016-12-31; Room Type ID 20583; Rate Plan ID 207782211; Inactive Rate Plan Updated Ref=[b44d7e4e-cf66-11e6-950b-e19b2852ebb6] </Warning>
    <Warning code="7022">Inventory date 2017-01-02; Room Type ID 20583; Rate Plan ID 203619420; Inactive Rate Plan Updated Ref=[b44d7e4e-cf66-11e6-950b-e19b2852ebb6] </Warning>
    <Warning code="7022">Inventory date 2017-01-03; Room Type ID 20583; Rate Plan ID 203619420; Inactive Rate Plan Updated Ref=[b44d7e4e-cf66-11e6-950b-e19b2852ebb6] </Warning>
    <Warning code="7022">Inventory date 2017-01-04; Room Type ID 20583; Rate Plan ID 203619420; Inactive Rate Plan Updated Ref=[b44d7e4e-cf66-11e6-950b-e19b2852ebb6] </Warning>
  </Success>
</AvailRateUpdateRS>','xmlns="http://www.expediaconnect.com/EQC/AR/2007/02"','')


select DISTINCT
    dbo.Wordparser(tbl.Col.value('/','varchar(max)'),3,';') 
  ,dbo.Wordparser(dbo.Wordparser(tbl.Col.value('/','varchar(max)'),3,';') ,2,'D')
FROm
 @xml.nodes('/AvailRateUpdateRS/Success/Warning') Tbl(Col)  

Result

------------------------ -----------
Rate Plan ID 207782211   207782211

The example below should work for you. Just adjust it to your environment...

    input XML
