1. Azure Synapse Workspace and Database: Ensure you have an Azure Synapse Analytics workspace and a dedicated SQL pool (formerly known as SQL Data Warehouse) where your data is stored.
2. Service Principal (App Registration) - In Azure Active Directory (AAD), register a new application. This will create a Service Principal. - Note down the **Application (client) ID**, **Directory (tenant) ID**, and **Client Secret** (you will need these for authentication).
3. Grant Permissions - Assign the Service Principal to the SQL role on the Synapse database with appropriate permissions. - For example, execute the following SQL command on your Synapse SQL pool:
```sql CREATE USER [YourAppName] FROM EXTERNAL PROVIDER; ALTER ROLE db_datareader ADD MEMBER [YourAppName]; ```
4. Configure Azure Synapse - Ensure that Azure Synapse is set up to allow access through the registered application. Verify that the Service Principal has permissions to access the Synapse workspace.
# Step 2: Install and Configure Qlik
1. **Install Qlik Sense**: - Ensure you have Qlik Sense installed in your environment.
2. **Download and Install ODBC Driver for SQL Server**: - Install the Microsoft ODBC Driver for SQL Server on the machine where Qlik Sense is installed. This driver supports Azure Synapse.
3. **Create an ODBC Data Source**: - Open **ODBC Data Source Administrator** on your Qlik server. - Create a new DSN (Data Source Name) with the following details: - **Driver**: SQL Server - **Server**: The fully qualified domain name (FQDN) of your Synapse SQL pool. - **Authentication**: Set it to "Azure Active Directory - Service Principal". - **Client ID**: The Application (client) ID of your registered application. - **Client Secret**: The Client Secret generated during the app registration. - **Tenant ID**: The Directory (tenant) ID from AAD.
4. Test the Connection - Use the DSN to test the connection. Ensure that it connects successfully to Azure Synapse.
# Step 3: Connect Qlik to Azure Synapse
1. Open Qlik Sense - Go to the Qlik Sense Hub.
2. Create a New App - Create a new app or use an existing one.
3. **Add a Data Connection**: - Go to the **Data Load Editor**. - Select **Create New Connection** > **ODBC**. - Choose the DSN you created earlier for the Azure Synapse connection. - Test the connection within Qlik Sense.
4. Load Data - Once the connection is established, you can select tables and views from Azure Synapse. - Load the desired data into your Qlik app.
# Step 4: Configure Data Load Scripts (Optional)
- Depending on your needs, you can customize your data load scripts in Qlik Sense to pull specific data or perform transformations.
# Troubleshooting Tips:
- Firewall Settings: Ensure that your Qlik server can reach the Azure Synapse SQL pool over the internet. Check firewall rules in both Azure and your local network. - ODBC Errors: If you encounter ODBC errors, double-check the credentials and permissions assigned to the Service Principal.
