how to get the object of an agent from the database table in anylogic 8


how to get the object of an agent from the database table in anylogic 8



In my anylogic project I have created a population of agent named DATA. This population contains 4 values that are being fetched from the database table. This means that there are 4 agents in this population. The table contains two columns i.e. data_id and data_state. Ultimately these become the parameters of this agent Data. Table sample is shown below:



data_id | data_state


d1 | delivered

d2 | delivered

d3 | undelivered

d4 | delivered



I am applying any condition in an event named "retransmit", based on which the object of undelivered data is to be fetched and then later on called. This event is in some other agent named SENDER. Once I have obtained the value "d3" by sql, how can I get the object of DATA with data_id 'd3' from SENDER?
What should I write?
main.datas.get(??)



I dont want to hard code this like: main.datas.get(2);



Does anybody know any method or a built-in function by which I can achieve this?

assuming that there is only one DATA with data_id=d3


Data theData=findFirst(main.datas,d->d.data_id==d3);



If there are many


List <Data> theDatas=findAll(main.datas,d->d.data_id==d3);





That's exactly what I wanted!.. Thanks alot :) .. Above code needs just a little correction, it should be like this: List<Data> theDatas=findAll(main.datas, d->d.data_id==d3);

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...

Opening a url is failing in Swift

Opening a url is failing in Swift breakpointing inside the callback and logging success shows false. I added itms-apps to my plist: LSApplicationQueriesSchemes and put this in my app delegate: func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { return true } func moreTapped() { let url = NSURL(string: "itms-apps://itunes.com/developer/quantum-productions/id979315877") if #available(iOS 10.0, *) { UIApplication.shared.open(url! as URL, options: [:], completionHandler: {(success: Bool) in }) } else { UIApplication.shared.openURL(url! as URL) } } Are you testing on a real device? – rmaddy Jun 21 at 23:57 I try on a device, get "Cannot Connect to App Store".
