Hello,

XE4 with UniDAC 5.0.1 with SQLite connection.

I try to start my application in iOS Simulator.
I have connected with ForceCreateDatabase and created all my tables but when I try to open first table with TUniQuery I have an EConvertError in TCustomLiteDataSetService.GetRecordCount() StrToInt().
I have UniDAC with sources and would like to see sources but you changed password for ZIP file, so I can't. My developer license number is 01811.

Hello,

We couldn't reproduce the problem, please send a small test application (the sources) demonstrating the problem to alexp*devart*com.
Please contact our sales*devart*com to get the new password for the sources.

Hello,

I have send an email to sales* yesterday before starting this topic. I will wait...
I tried to make a test project but I can't reproduce so I prefer to debug myself before to try more with test project.

Hello,

I received the sources and I found that if I check UniQuery1.Options.QueryRecCount I can reproduce the error in iOS Simulator and Device but not in Win32.
If you still can't reproduce please tell me so I will send you an test project.

Hello,

I've send an email to you with two projects. One is for iOS and other for Win32 but I think is related to what is happening in iOS.

Hello,

Thank you, we have received your sample and reproduced the problem. We will inform you as soon as we have any results.

Hello,

We have fixed the problem on the iOS simulator and a real device, this fix will be included to the next build. The error, that occurs on our sample on a win platform, is correct, since the field value is NULL and there is no such field in the table, therefore SQLite returns the type of such field as TEXT. To solve the problem, you can use the IFNULL method for conversion of the null value to 0, i.e.:

Thank you, I used COALESCE because is similar and compatible with all servers I use.

Hello,

Yes, you are right, using COALESCE is one of solutions for this problem.
