SQL Server express not connecting with PowerApps

Hello guys.

I am trying to use the SQL Server Express Editon as data source. Is that possible?

I am having some trouble to use it as conector to PowerApps. I insert the server name, data base, user and the password. I am using the cloud option, but can not connect it.

Hi @JoaoN 

 

Yes Express works perfectly. Are you sure there isn't a firewall getting in the way? Can you connect to the SQL server from the internet or are you using an on premises data gateway?

 

Maybe sent us a print screen of the error.

Hi @JoaoN 

Yes, it's possible to connect to SQL Server Express Edition.

You'll need to select the on-premises gateway option, rather than the 'Cloud Services' option. We use the cloud option to connect to SQL Azure.

You'll need to install the on-premises gateway on a machine in your local network. There shouldn't be any antivirus/firewall rules that block connectivity between the gateway and the SQL Server.  For the 'SQL Server name', you'll need to specify the instance name (for example MyServer\SQLExpress). You should also make sure that the SQL Server Browser service is running on the machine with SQL Express.

Hi @JoaoN ,

Does the SQL Server Express Editon exist on your local PC or Azure Cloud?

 

If the SQL Server Express Editon exists on your local PC, I think there is something wrong with your Operation. When you connect to On-premises SQL Server, you need to choose "Connect using On-premises data gateway" option:3.JPG

Note: If you want to connect to On-premise SQL Server from PowerApps, you need to install On-premises data gateway firstly on your PC.

 

More details about connect to On-premises SQL Server from PowerApps, please check the following article:

Hi @JoaoN ,

For your first qustion, if you want to connect to Azure SQL Table from PowerApps, you must have a proper Azure Subscription for your account already (subscribe to Azure).

 

Fo ryour second question, yes, you are right. If the PC which installed the Local SQL Server is online, you could connect to the Local SQL Server from PowerApps through the On-premises Data Gateway.

If you turn off the PC, you would not be able to connect to the Local SQL Server from your PowerApps app through the On-premises Data Gateway.

Hello guys, thank you for your response @v-xida-msft , @timl  and @DavesTechTips !

 

I am new guy at this point. I never worked with SQL as data source, but I am trying powerapps and I notice that maybe it will work better with SQL. So I am trying the SQL Server Express. I am not a technician but I like this IT world. So, I just downloaded the SQL Server Express and the Management Studio. I give my new user all the permission and did a tutorial that configure the firewall.

 

After you explain to me something about the 2 option of connect to SQL I have two questions.

1- To use the cloud services option, Do I have to buy the Azure?

2- Connect using on premises means that  the comunication to data source will be possible just if the pc that have the SQL Server installed is online? Or can I turn off this pc and use the patch function whenever I wanted?

 

Thank you guys!

Hello @v-xida-msft , @timl , @DavesTechTips !

 

Thank you for your time! I am now using on premises gateway and it is working. I am just trying out if this will be really necessary to me or if just excel would be fine to my situation. So if SQL be best to me, I am going to buy the Azure plan to use SQL cloud option.

 

I am not IT professional, just someone that like this awsome area. So I have to learn absolutely everything! Now I am having some trouble with primary key that I have already configure on SQL but still having some issue.

At Edit/Add screen, the MaxLenth property from datacard is not working well. It shows up this error: "The 'DataSourceInfo' Function has some invalid arguments". I do not figure out what this means!

 

Well done @JoaoN 

 

Have lots of fun with the platform, it is changing so many people's lives around the globe!

 

PS: Stick to SQL or SharePoint lists. Excel is really means for small single user apps.

PS2: What is the formula that is currently in the MaxLength property?
