I'm trying to replace excel data source to SQL Server on-prem.
My table is created and I have tested creating sample app using that datasource and it works.
But, trying to do the same I face issue
1. “An entry is required or has invalid value” exception.
2. I'm trying to store image that user choose into a Blob object in SQL Server. That's not working even in sample app I have created.
Can you please help. Thanks.
The Error message means there are fields not filled right in your code.
For SQL Server to work, the Primary Key is needed when creating new records, further, make sure the data inputted would meet the field requirements defined in your SQL Table.
For how to work with SQL Server, see:
If you still have issues after adding a primary key (as @v-micsh-msft suggests) you may also want to try adding a TimeStamp field to your SQL Server table. I have had issues in the past with both Access and PowerApps which were resolved by adding a TimeStamp field, so I now add one to every table as a matter of course... so to be fair, that issue might be resolved but I'm not going to remove my TimeStamp fields to check 🙂
If you are using on-premise SQL Server I recommend using SQL Profiler to see what is going on. Connect to database, setup app to save blob, clear Profiler, execute save and look at results. I general copy the save SQL in Profiler to SSMS and execute query. I've used this technique numerous times with great success.
I wrote a post at https://powerapps.microsoft.com/en-us/blog/converting-the-shoutouts-template-to-sql-server/ with detailed instructions on how to do this customization, please take a look and hope this helps!
Thanks @CarlosFigueira, it's an interesting read.
The issue we have is finding the gateway - when I install a gateway on my local machine PowerApps can find it, however when I install a gateway on another server it can't find it to connect to it. Any ideas?
@mbutterz not sure about the problem with the Gateway. I know that there's currently an issue that updates to SQL tables don't get propagated quickly, but it doesn't sound related. I'd suggest you created a new thread with this case, as there may be people that know more about the gateway than about customizing a template.
I'm just going through your blog post now and some of your instructions don't match up with what i'm seeing. Perhaps the template has been updated since I last started working on it.
For example the names of the galleries are different, and there are no OnVisible properties for the SentConfirmationScreen.
EDIT: I went back to the templates and created a fresh app from the Shoutouts template, and it seems it has been updated since I last created it. However when I set it up I can't click on anything or send any Shoutouts!
Honestly I can't begin to tell you how long i've spent trying to make this most basic of apps do what I want it to do.
PowerApps is supposed to enable us to create enterprise apps and yet i've had to trawl forums and youtube videos and make numerous help desk calls to microsoft just to make the bloody things work!
It's incredibly frustrating and frankly the time we all spend making these apps work we might as well just fork out and pay for a more professional and polished third-party app that just does what it's supposed to do!
