ER7 message from DataBase to SOAP sender

Re: ER7 message from DataBase to SOAP sender

With ORACLE, it works with this transformer.
But I would like it works without reading another time the database. It is more efficent.


===============================

var ds= new Packages.oracle.jdbc.pool.OracleDataSource();
ds.setURL('jdbcracle:thin:@//172.30.250.119:1521/XE'
var conn = ds.getConnection('HORUS','criminal& #039;
var stm = conn.prepareStatement('SELECT MENSAJE FROM SIGLO.HL7 WHERE ID='+msg['id'].toString());
var rs = stm.executeQuery();
rs.next();
var cl = rs.getClob(1);

var strOut = new java.lang.StringBuffer();
var aux = new java.lang.String();


var br = new java.io.BufferedReader(cl.getCharacterStream());

while ((aux = br.readLine())!= null) strOut.append(aux+'\r\n'

globalMap.put('msgDB', strOut.toString());
logger.info('msgDB: ' + globalMap.get('msgDB&#039);

conn.close();

Re: ER7 message from DataBase to SOAP sender

I am unable to read ORACLE CBLOB field.

In my raw Data appears a value of kind

<?xml version="1.0" encoding="UTF-8"?>
<result><mensaje>[email protected]</mensaje><id>1</id></result>

and I don&#039;t know the type of CLOB field "mensaje". I tried cast to oracle.sql.CLOB but doesn`t work.

In another topic I read something that the following (access in transformer to the data with a database connection).

var dbConn = DatabaseConnectionFactory.createDatabaseConnection (&#039;oracle.jdbc.driver.OracleDriver&#039;, &#039;jdbcracle:thin:@//XXX.XXX.XXX.XXX:1521/XE&#039;, &#039;USER&#039;, &#039;password&#039;
var result = (Packages.java.sql.ResultSet) (dbConn.executeCachedQuery(&#039;SELECT MENSAJE FROM SIGLO.HL7 WHERE ID=1&#039);
result.next();
var cl = result.getCLOB(1);

.......

dbConn.close();


but I get the following error

It seems a problem with ORACLE driver.

Any ideas?

SELECT ID,MENSAJE FROM SIGLO.HL7 WHERE ESTADO=&#039;P&#039; AND SENDER=&#039;MYSENDER&#039;

Re: ER7 message from DataBase to SOAP sender

What does your SQL statement look like?

[fernando.ramirez]

I have my ER7 HL7 messages in a database with id,status and message fields.
I want to send these messages via SOAP sender in a XML HL7 format.

I have the ER7 message like a CLOB oracle field.
How do I read this field? I try indications from another posts but I don&#039;t how the class of msg[&#039;message&#039;] field.
This is my transformer.
