Introduction

In this article will be shown how to import data from an Excel file into Azure Mobile Services in order to be used by your App. It's assumed you have created your own service else follow this guide on how to manage Azure Mobile Services.

Tools

In order to import data from your local database or Excel file you need to install last version of Microsoft SQL Server Management Studio Express (SSMSE), a free and easy graphical tool to use for managing SQL Server database with Advanced Services.

Importing Data

First step, in order to avoid connection issues is to set Firewall Rules to allow your IP address to connect to DB.

Microsoft SQL Server Management Studio

Opening Microsoft SQL Server Management Studio will be asked to connect to a server.

Select the server name you choosed during creation of your Mobile Service and select SQL Server Authentication option.
Once logged you can browse your remote databases, tables and perform queries.

Now we need to access to a local resourse in order to upload data from local to Cloud. To do that click on connect button on top left of the explore object column and select database engine. Will be shown the same window at startup and select your local address ( tipically localhost or network path ) and select Windows authentication.

if don't have one create a new local database

Right click on your local database -> task -> import data

Opened the import / export wizard, select Microsoft Excel as data origin and the right version of your Excel file

The next step is to select the destination server and of course will be our remote Azure Db

Select the first option: Copy data from one or more tables or views

Now you will be able to see the content of your Excel file. Note that each sheet will be seen as a table

Selected the sheet you want to import let's click on Modify Mapping and then on Modify SQL Code

Add the following line [id] int identity primary key, into the script. This will be our primary key. Remeber that each table must have a primary key named Id. The code should look like that:

CREATE TABLE [dbo].['TABLE - NAME$'] (
[id] int identity primary key,
[Tipo] nvarchar(255),
[Descrizione] nvarchar(255),
[Immagine] nvarchar(255)
)


Go forward

If no errors occurs you should see a result like that

Now data are imported into Db and your expectation is to find tables also into your Mobile Service, but checking you still will not find them, You need to perform other operation to link your Mobile Service with your Database. To do that, go into SQL Database section, select your Database ( nokiadeveloepr_db for our tutorial ), open the Dashboard section and click on Manage

The Database Management Portal will be opened

Select a New Query

execute the following queries:

CREATE SCHEMA nokiadeveloper;
ALTER SCHEMA nokiadeveloper TRANSFER dbo.yourtablename;

We created a new schema with the same name of our Mobile Service and linked our table to it in order to access to this data from Mobile Service.

Go on your Mobile Service section and create a new table with the same name of the table created into database. At time of creation you will see just 1 record, but don't warry, click on it and all records will appear macically.
