SQL Azure Source Connector
The SQL Azure source connector in DataSync lets you retrieve data from Microsoft Azure SQL Database for loading or synchronizing in your data warehouse. After creating all required source connections, configure your destination source to complete the connection setup.

Parameters
Connection properties
| Parameter | Description |
|---|---|
| Description | Unique name for the connection. Example: SQL Azure |
| Server | Fully qualified server name where the Azure SQL Database is hosted. Example: salesdb.database.windows.net |
| Database | Name of the Azure SQL Database to connect to. Example: SalesData |
| Username | Login account for accessing the database. Example: dbadmin@salesdb |
| Password | Password for the specified username. |
| Timeout | Time in seconds to wait for connection opening and query execution before timeout. |
Additional connection properties
Additional connection string properties not specified in the Connection Properties panel. For each property added, you can choose Visible or Encrypted. Selecting Encrypted hides the value from the interface and stores it encrypted in the back end, such as when defining passwords.

| Value | Value for the property. Example: True |
| Type | Visibility of the property: Visible or Encrypted. |
Advanced settings
Advanced settings control how the SQL Azure connector tracks changes, handles regional and time configuration, and processes data batches during extraction. These options allow fine‑tuning for performance and accuracy, and should be configured according to your system environment and operational requirements.
| Setting | Description |
|---|---|
| Tracking Type | Method for tracking changes: None or Date. |
| Region | Region setting for the connector, if required by your setup. |
| Time Zone | Time zone matching the SQL Azure application server. |
| Time Offset | Refresh offset in seconds to compensate for timing issues in record selection. Minimum value is 0; maximum is 3600 seconds. |
| Batch Size | Quantity of records processed in each batch during extraction. Larger batch sizes increase memory usage but can improve performance up to a point. The default value is 2000 and the maximum should not exceed 10000 records. Adjust according to your network speed and disk performance; in most cases the default (2000) works best. |
