Querying XML using Oracle SQL developer

Querying XML using Oracle SQL developer

Querying XML using Oracle SQL developer

Hi all,

First let me set the scene. I am very new to XML and got a reasonable understanding of sql.

I have a database that amongst other things has a column in a table that contains the following XML.

"<Request action="Update">
<PayRuleName>RT - 30 Min Auto Ded >39</PayRuleName>
<LaborAccountName>Food/North West RT/North West Region 4 RT/North West Area 44 RT/Late Shop Ellenbrook/-/-</LaborAccountName>
<PersonData><Person><AccrualProfileName>Holiday & Lieu Time</AccrualProfileName>

What I would like to is extract the personnumber shown in the first row. Have done muh research and I am trying to use the following script,

select EXTRACTVALUE(xmltype(xmlreqbody), '/Personality/Identity/PersonIdentity/PersonNumber')
from failedxmlbody

This will eventually be incorporated into a larger select statement that I have completed already. It's just this bit I need to get working.

Go easy on me, as I am new to this.


RE: Querying XML using Oracle SQL developer

So I guess it's not working, right? What error are you getting? Any help here?

Btw, do you consider a good idea to store XML files on a database?


RE: Querying XML using Oracle SQL developer

Well, the XML fragment is obviously not well formed so I think you will have problems
a) Storing it as XML and
b) using Oracle XML built in functions to process it

One solution is to store is as a CLOB and use regular string fucntions to parse it. Its a bit clunky and might not scale too well but here goes:-

SQL> create table failedxml(test clob)
  2  /

Table created.

  1  insert into failedxml(test)
  2  values(
  3  to_clob
  4  (
  5  '<Request action="Update">

In order to understand recursion, you must first understand recursion.

RE: Querying XML using Oracle SQL developer

Thank you to Taupiro.

I actually ended up using a similar script to yours before I saw your reply.

My script is as below:

XMLREQBODY,substr(xmlreqbody,(Instr(xmlreqbody,'PersonNumber')+13),(Instr(xmlreqbody,'/PersonNumber'))-(Instr(xmlreqbody,'PersonNumber')+14)) as PersonNumber

(This is part of a much bigger select statement)
