<div dir="ltr">What you have described is half of the usage of binding variables. You can bind a variable to a fact or to individual fields of a fact. You can then use those variables in the LHS or the RHS of your rules.<div style>
For example:</div><div style><br></div><div style>1.- Find different Person objects</div><div style><br></div><div style>when</div><div style> $p1: Person($name1: name)</div><div style> $p2: Person($name2: name, <b>this != $p1</b>)</div>
<div style>then</div><div style> System.out.println("Found "+$p1+" with name '"+$name1+"' and "+$p2+" with name '"+$name2+"'");</div><div style>end</div>

Hi,<br>
<br>
I am having little bit difficulty in understanding "binding variable"<br>
concept in the guvnor. During our POC a business user asked me question<br>
around this and i was able to save myself by telling them that the binding<br>
variable is used in case you want use the fact again in Then statement.<br>
(This is how i see it in the examples of rules).<br>
<br>
Can anyone please explaining me the real use of the binding variable so that<br>
i can help my business partner understand it properly?<br>
<br>
Thank you for your help in advance<br>
<br>
Isha<br>
