Hi,<br />
I am working in delphi 3.0 using &nbsp;'Paradox' ..I have two tables which are order_master and order_detail and i have a form in which both have master detail relationship i mean its a master detail form using the above tables..and cahcheupdate property is true in both tables.<br />
<br />
So in case of keyviolation in detail table I want to trap this keyviolation on order_detail &nbsp;but you know when cahcheupdate is true then it wont work coz changes are going in a temporary area...not physically...so is there any method of preventing duplicate values in detail when cacheupdate is true...<br />
<br />
your help in this matter will higly appreciated...<br />
<br />
thanks,<br />
