I have created a Xamarin where I want to query one database on a Azure SQL Server and regarding which result I get back I want to query one of X numbers of certain databases.
We have developed xamarin.forms application with azure sync and it's working fine.
Once we release the app, it may used by different users, so we have to create different databases for each user. So when an user is logged in, we have to read the corresponding database name(Connection string)for that user from one database and has to pass the value(database name/connection string) to the .Net Back-end for the syncing purpose.
i.e, I want to query one database on a Azure SQL Server and regarding the result I get back I want to query one of X numbers of certain databases.
How can we achieve this with Azure Offline Sync Service?
Or, shall we have to follow any other workaround?

I am using Logic Apps Designer on Azure to move source data to a storage file and I need to connect to a database on my SQL Server. To do this, I am using an on-premise connection througha gateway. I was able to successfully connect to my SQL Server database, however, when I am using Logic Apps action, not all tables are available on Logic Apps. Is there a security/permissions/connections issue that is preventing all tables from the SQL Server database not to return to Logic Apps?
enter image description here

I tried refreshing/restarting Azure and also tried connecting through with other authentications hoping more tables would return, but no luck.
I would suggest you to create a new api connection to sql and try to access tables again. There might be issue with connecting to db.
One of the alternative approaches to get row from sql db is using execute query action in logic app.
As shown in above picture, Execute a SQL query (V2) action is used to query table and retrieve records based on condition.

I am looking for a proper solution architecture for a data transfer scenario from SQL Server to an external API and then from the API back to SQL Server. We are thinking of using Azure technologies.
We have a database hosted on an Azure VM. When the value of the author of the book table changes, we would like to get all the data for that book from related table and transfer it an external API. the quantity of the rows to be transferred (the select-join) is huge so it takes a long time to execute the select-join query, After this data is read it is transformed and then it is sent to an external API (over which we have no control) The transfer of the data to the API could take up to an hour. After the data is written into this API, we read some reports from this API and write these reports back into the original database.
We must repeat this process more than 50 per day.
We are thinking of using Logic app to detect the trigger from SQL Server (as it is hosted in Azure VMs) publish this even to an Azure Data grid and then use Azure Durable functions to handle the Read SQL data-Transform it- and Send to the external API.
Does this make sense? Does anybody have any better ideas?
Thanks in advance
At this moment, Logic App SQL connector can't detect when a particular row changes, it will perform a select (which you'll provide), and then it will check for changes every X interval (you'll specify).
In other words, SQL Database doesn't offer a change feed like CosmosDB where you can subscribe to events and trigger an Azure Function.
Things you can do:
1-Add a Trigger on SQL after insert / update which will insert the new/changed row into a separated table, and then you can use Logic App / Azure Functions to query this table and retrieve data.
2-Migrate to Cosmos DB and use the change feed + Azure Functions
3-Change your code to after insert into SQL Database, also add a message with the Identifier for the row you're about to insert / update, then add it to a Queue, which will be consumed by Azure Function.
I have created a Mobile App and Database in Microsoft Azure. Now I am trying to create Easy Tables from Mobile App but I am getting error message "You need database to use East Tables. Click here to create one.
Even though I have existing database Easy Tables doesn't list it.
Below is the screenshot.
I have mapped Data Connection with mobile app, below is the screenshot
It would be great if anyone can help, I am new to azure.
Your connection string must be created with name: MS_TableConnectionString
Just because you have a database doesn't mean it is linked. Click on Data Connections, then Add, then add your existing SQL database.
Note that Easy Tables won't recognize the existing tables unless you add them through Easy Tables. There are notes around the format of Id (it needs to be
a string) and other fields.
When you created your Database Server did you check "Allow azure services to access server"? That could be why you cannot see the Database listed.
I am trying to get to grips with Azure Mobile Services and am a little lost about which Azure services I should be using for what. When you set up a new Azure Mobile Service you only get the option to create it with Microsoft SQL Server as the database. Can you configure it to use the documentDB service instead?
Also a lot of what I read about Azure Mobile Services seem to be setup around storing data for a particular user. Is this the correct place to store data and query it for all the systems users rather than an individual or should that be handled elsewhere?
thanks
Andy
using the .NET backend, you have a choice of using Azure SQL Database,MongoDB or Table Storage. There's no out of the box support yet for DocumentDB, but you can make it work as shown here
what you store in the storage listed above is up to you, there is no specific reason/restriction/limitation that's its only for user specific data. the samples just happen to show that.
You may use any backend database service. It's true you have to set up SQL when you create a new mobile service space. And the SDK has a Table provider that maps to SQL (or MongoDB). However, you can ignore all that if you want. As long as you can access the appropriate driver for your database-of-choice, you can make calls to the database from the API backend methods. This is especially true when building custom API methods.
I am working on a solution that uses SQL Azure. Part of the project deals with backups and using the DAC Web Services for backups.
The issue is that there is a different endpoint depending on which region the Azure SQL database is in. As I am working with multiple groups, and cannot ensure which region the database will be in, I am looking for a way to programmatically determine the region.
The region is also important, as I want to copy the backups to a different region just to be on the safe side.
I know that I can look in the Admin console, but I would like to use code to solve this problem.
Additional information:
The application is running on Azure using Worker Roles for functionality.
I do not have access to all of the account-id's to use the full REST API.
I do have access to the master database on the Azure Sql Server.
Working on this in C# (I failed to put the language)
You can use Get Servers request (GET https://management.database.windows.net:8443/<subscription-id>/servers) of Azure REST API to enumerate SQL servers which gives the Location or Region more info at msdn -> http://msdn.microsoft.com/en-us/library/windowsazure/gg715269.aspx
