Can you perform a search that is executed on the server and

Posted by jsniemi79 on 11-Nov-2014 14:24

I am building a mobile app and need the ability to search for certain values to limit the amount data being returned to the device.  I know I can use a list item and data filter to limit records on the client side, but I really need to be able to submit a value, like a name, and have it return only records matching that name.

Is this possible today?

Thank you in advance for your time.

Hello,

Did you check this document explaining how to do a search in a Rollbase Mobile App? https://community.progress.com/.../971.aspx.


Thank you,

Gian

HI Gian,

I have used the data filter before which in this case, I believe, is just filtering the records in your list that are returned by your view.  When I ran through an example like that, I wasn't able to filter items that didn't show up on my first page, so the end user could not find the record they are looking for.  If I leave the rows per page value blank, it doesn't appear to bring back all my records anyway, which is good.  In this case, I am talking about 50,000 records that I need to be able to search through and return values by name.

In my example below, I set the rows per page to 3.  I have an account that returns on this list called AA Maintenance.  If I try and use the data filter from the list, I cannot get the value to return, because it wasn't one of the first 3.

Hello,

I see. I think you are right about the data filter search being a client side process only. Let me get back to you while I check if the server side search functionality already exist in the current Rollbase Mobile version.

Thanks,

Gian

Thanks Gian,

This app is running on 3.0.2, so if there is something in a newer version, please let me know.

Any luck on this Gian?  It is a huge issue for us and could be a show stopper with our current client as well as future clients if we can't perform a server side search.  We just can't take the performance hit of returning all these values when the dataset is so large.

Any thoughts on this one?  I really need to know if there is a way for me to hit an API in Rollbase from a mobile device that will allow me to search on the server rather than return all records.  This is a potential show stopper for my client.  Any response is appreciated.

Thanks,

Jason

Hi jsniemi79,
 
In theory, this is possible using the selectQuery API provided by Rollbase. We can create a REST service in Mobile App Builder environment using the selectQuery API and appending the valid session (as mobile requires a valid session attribute to make REST call to Rollbase) in the REST call might do the trick (this method will perform the server side search). I haven’t tried this approach.
 
Hope this helps.
 
Thanks and Regards,
Anil Kumar.

Hi Anil,

Can you give me some direction on where to get started to try this?  I'm not a developer, so this is a little new to me.

Thanks,

Jason

How do you append the session ID to the service?

I've got the selectQuery service created and can run a test which is returning accurate results.  I pulled a RSessionID from Fiddler to test, but I don't know how to get that same value to pass to my query.
