texte = Here's the code in my trigger template which is requested once per second. Instead of trying to create 45 new records in a couple of seconds I have resorted to creating only 1-4 new records per second (although I want to create many more for a truly realistic auction simulation).The tickets.db holds all the bidderID (sku) values. I need to search this db and retrieve a series of random bidderID's for the replace contexts:***************************************************************[hideif [getchars start=4&end=5][time][/getchars]\2][showif [getchars start=7&end=8][time][/getchars]\11][search db=test/tickets.db&eqemaildatarq=XXX&raemailsort=1&max=[math]ceil((1+[random])/25)[/math]][founditems][replace db=test/bids.db&eqbidderIDdatarq=[blank]&asidxsort=1&idxtype=num&max=1]bidTime=[time]&bidderID=[sku][/replace][/founditems][/search][/showif][/hideif][showif [getchars start=4&end=5][time][/getchars]\6][showif [getchars start=7&end=8][time][/getchars]\17][search db=test/tickets.db&eqemaildatarq=XXX&raemailsort=1&max=[math]ceil((1+[random])/25)[/math]][founditems][replace db=test/bids.db&eqbidderIDdatarq=[blank]&asidxsort=1&idxtype=num&max=1]bidTime=[time]&bidderID=[sku][/replace][/founditems][/search][/showif][/showif]***************************************************************Naturally I cannot use this technique with replacefounditems because I'm searching in a different db than where the records need to be replaced. But there may be another way to approach this problem. I think this might work faster:1- Search the tickets.db for (example) 45 random sku values2. Stores these skus in an indexed table3- Search the bids.db for the next 45 records with blank bidderID values4- Use replacefounditems to change these bidderID's based on lookups of the index values in the tableI don't know if this will be faster or not, but it's probably worth a try as soon as I have some free time again.Sincerely,Kenneth Grome
