<br> Yes. The same way that the order in SQL statements matter. So always write more constraining patterns first and you will get huge performance benefits.<br><br> []s<br> Edson<br><br><div><span class="gmail_quote">

All,<br><br>I was wondering [and maybe this has be answered before] ,but does the order of the rules in the when clause matter?<br><br>For example I have the following:<br><br> rtvHeader : RtvHeader( headerRtvNumber : rtvNumber )
<br> repaymentCode : RepaymentCode( actualCode : code, matchApprv != "Y" )<br> lineCharge : HeaderAdditionalCharge( rtvNumber == headerRtvNumber, originalRepaymentCode == actualCode )<br><br>In my case there is a higher likelihood that I will have more RepaymentCodes than RtvHeaders [1 of these guys] and likely less HeaderAdditionalCharge objects. So should the order be more like:
<br><br> rtvHeader : RtvHeader( headerRtvNumber : rtvNumber )<br> lineCharge : HeaderAdditionalCharge( rtvNumber == headerRtvNumber, originalRepaymentCode : originalRepaymentCode)<br> repaymentCode : RepaymentCode( actualCode == originalRepaymentCode, matchApprv != "Y" )
<br><br>Or does it not really matter?<br><br>Thanks in advance,<br><br>Ron<br>
