am I correct in believing this isn't as much about programming, as it is about learning how to use that tool? – Stultuske
it contains both, programming by java or using Business-central with little programming (what I use now) – Asma Alghamdi
so far, based on your question, all you try is setting some fields in a UI. – Stultuske
yes and I can point to java file to do some code as a data object, so if you have any code suggestion it can handle it – Asma Alghamdi

First of all do all the necessary setup of the "Execute SQL" Service task as described here.

Create a process model where you add the "Execute SQL" task followed by a Human task. Next add a new Process variable of type the java.util.ArrayList to your process model. Open the properties for the Execute SQL task, configure as assignments (data output) the previou created process variable. Open the properties for the Human task, fill in actor and configure as assignments (data input) the list variable.

Create a new form where you choose the Human task of your process. Pull the assigned variable from the left on the form. In the dialog choose as field type 'multipleselector', select 'required' and unselect 'read only'.

I found out that there exists a JBPM issue (https://issues.redhat.com/browse/JBPM-9595) that blocks using the 'multipleselector' component. Until this is fixed you may want to use the 'multipleinput' instead.
