How to retrieve multiple rows from database using WSO2 ESB?

Question

I want to retrieve multiple rows in a db using wso2 esb. Using dblookup mediator I am able to retreive only one row. It is suggested to use WSO2 DSS can you please help

Answer 1

If you don't want to use DSS (which is our case), then you might try the custom mediator that can be found here.

Answer 2

Data Service server is used to expose your data(base) ,with sql ,as an available xml/restful web services . You could then call the data service through its endpoint from your ESB proxy service, receiving your result set(any # rows), so it is suited to your requirement.

Perhaps you should try to experiment with it first and post any issues you arrive at.

Answer 3

I got it working without DSS.
just write a script mediator to call dblookup or dbreport mediator as many times as how many rows required.

var a=mc.getSequence('gett');
        a.getList().get(0).mediate(mc);
        a.getList().get(1).mediate(mc);
        a.getList().get(2).mediate(mc);

here 'gett' is my sequence and it has 3 child so i'm call all three.
