This is straightforward: You use $param, as usual, in the code snippet, and the list in the cell below:<br><br>Data<br>coverType in ( $param )<br><br>"A","B", "C", "D"<br>"X","Y","Z"<br>
<br>To obtain the actual value from the fact, use a binding variable and refer to this in the action.<br><br>Data<br>$ct: coverType in ( $param )<br>--------------------<br>result<br>add( $ct )<br><br>and an 'x' in the cells below, where required.<br>

Hi,<div><br></div><div>I am pocing/learning drools and I am trying to implements Compound Value Restrictions using 'In' in a decision table.</div><div><br></div><div>I can do this in a rule like</div><div><br></div>
<div><div>rule "CoverType Example"</div><div>when</div><div> $risk : Data( coverType in ("A","B", "C", "D"))</div><div>then</div><div> result.add("CoverType was one of A, B C or D");</div>
<div>end</div></div><div><br></div><div>I can also implement this in a decision table in a long winded fashion</div><div>Condition, Action</div><div>Data, result</div><div>coverType, add("$param")</div><div>
<div>A, CoverType was one of A, B C or D</div></div><div><div>B, CoverType was one of A, B C or D</div></div><div><div>C, CoverType was one of A, B C or D</div>
</div><div><div>D, CoverType was one of A, B C or D</div></div><div><br></div><div>Is there a compact way to do this using a Compound Value Restriction using in?</div><div>Something like:</div>
<div><br></div><div><div>Condition, Action</div><div>Data, result</div><div>coverType in, add("$param")</div><div><div>"A,B,C,D", CoverType was one of A, B C or D</div>
</div><div></div></div><div><br></div><div>What goes in the script part "coverType in"?</div><div><br></div><div>The number of items in the list can be variable, so don't want to write something that has $1, $2, $3, $4</div>
<div><br></div><div>Thanks</div><div>David</div>
