Receive multiple OBX segments

[nilesh]

What is the standard way to receive multiple OBX segments. E.g. (ORU^R01) pathology results.

I can see how the one to one mapping works, but what happens when there are unknown number of results being returned.

Re:Receive multiple OBX segments

In Javascript step:

for (obx in msg..OBX){
  output+=obx['OBX.5'].toString();
}

Re:Receive multiple OBX segments

Chris thankyou for the quick reply.

What would you recommend as the best way to go about saving each OBX result as a seperate row in a table? Could you provide an example. Thanks!

To a single record in the DB?

Re:Receive multiple OBX segments

Hi all,

sorry for my sudden appearance!. jasonlan, depending in how you manage "for each" loop is possible to concatenate all strings in order to generate only one record in database, or generate one record for each text.

If you concatenate al OBX segments in a var called report and when exiting the loop record the data in database, you will obtain one report. Otherwise, if you read all OBX segments and put the INSERT statement inside the loop, you will generate one record for each OBX.

It's your choice!

HTH,

Re:Receive multiple OBX segments

Thanks for your sudden appearance, I really appreciate it. :-)

would you happen to have a code example to help a slow person like me? ;-)

[ricber]

Re:Receive multiple OBX segments

Hi jasonslan,

search 'for each' in forum search and you will find many examples about, is really easy!.

Re:Receive multiple OBX segments

you know, I really don't know what I'm doing, I tried adding the example ChrisL supplied above as a javascript step in my transformer, but it always errors out with "ReferenceError: "output" is not defined."

can anybody help point me in the right direction.. (like I stated, I really don't know what i'm doing, but I can follow directions.. :-)

Re:Receive multiple OBX segments

Hi jasonlan,

maybe if you send your channel or javascript code that you re using we could help you.

Re:Receive multiple OBX segments

I have the same problem. I tried using the script that Chris posted higher in this post and get the same output error. No one ever answered, is that code missing something like a variable definition or something? Unfortunatly like the original poster, I'm new to this and don't know any Java.

Re:Receive multiple OBX segments

Hi Jason,

did you solved your problem?. Really is very difficult to help you without a code to comment.

Waiting your news,

Re:Receive multiple OBX segments

Adding the output={}; prior to the code seems to have gotten rid of the error, but it didn't actually output anything to my transformer / destination. Could someone tell me how to map a transformer java script step to my FileWriter template?

I tried adding ${output} to my template but that doesn't work. I also tried ${Reportoutput} which is the name of the Transformer step that is assigned to the javascript. Can anyone enlighten me?

JAVA CODE:
output={};
for each(obx in msg..OBX){
output+=obx['OBX.5'].toString();
}

This is in Step 8 of my Transformer Named "Reportoutput" of type JavaScript.
In my FileWriter Template I have some mapped one to one variables (steps 1 through 7 of the transformer), and I need all these OBX fields after the other steps. Please help.

Re:Receive multiple OBX segments

If you are using version 1.8 as I am, it seems that the code earlier in this thread will not work for you.

you need:

var output = {}
for(obx in msg..OBX)
{
  output+= msg['OBX'][obx]['OBX.5']['OBX.5.1'].toString();		

}

for(obx in msg..OBX) does not seem to iterate across the objects. It iterates across their indexes. The type(as much as a js variable can have a type) of obx is integer. A call to obx['OBX.5'].toString() throws an exception for trying to call a method that is undefined.

I am curious to see how I am going to work out mapping multiple OBX segments with multiple OBR segments...

[ajay_007]

declare output as var Output
and use in code
if u want to use it over channel then decalre channelMap.put('VArname',output);

[Guest]

Hi all,

I'm using this code below to create a string from all the OBR.4.1 values but the result of the variable is: [object Object]MG BSE ANNE DIFF KR NAK TSH KR CA. Where does the [object Object] piece is coming from? I want to get rid of this...

var output = {}
for(obr in msg..OBR)
{
output+= msg['OBR'][obr]['OBR.4']['OBR.4.1'].toString() + "\r\n";
channelMap.put('testcodes',output);
}
