Method 2: Using Microsoft SQL Server Integration Services (SSIS) to Set Up SQL Server REST API Integration

The Microsoft SQL Server Integration Services(SSIS) is a robust component and functionality of the Microsoft SQL Server Database that allows users to carry out numerous complex data migration tasks easily.

It houses support for and provides various tools such as data warehousing tools that help automate ETL to some extent, workflow tools to automate the data migration process, and a diverse set of data integration tools that allow users to unify data.

It also supports connecting with REST API-based sources and lets users ingest data into their Microsoft SQL Server databases.

You can set up the SQL Server REST API Integration by leveraging the connection manager using the following steps:

Step 1: Defining a Data Flow Task

Defining a Data Flow Task: SQL Server REST API Integration.
Image Source: Self

To start setting up the SQL Server REST API Integration, you first need to define a new data flow-based task. You must specify the Microsoft SQL Server ADO.Net destination and new REST source.

To do this, go to the connection manager, add a new connection, and choose the connection type REST by selecting the REST option from the dropdown list.

This is how you can define a data flow task.

Step 2: Configuring Connection Properties

With your task now added, you need to configure the properties for the connection. To do this, you will have to specify the connection properties such as the REST URI, your credentials, and the authentication format, choosing between OAuth, HTTP, NTLM, and Digest, along with information about the incoming file format like JSON, XML, etc.

Configuring Data Mapping and Destination Properties: sql server rest api

Once you’ve provided the necessary information, you need to specify the “DataModel” property that helps map incoming data into database tables.

You can choose between the following options for the DataModel property:

  • Relational: This helps ensure that mapping for incoming data takes place in a way that maintains referential integrity.
  • Document: This helps map data into nested or hierarchical data documents.
  • Flattened Documents: This helps aggregate data from nested documents and their parent documents into a single table.

This is how you can configure the connection properties.

Step 3: Configuring Extraction Properties of REST Data Source

With your connection properties now configured, you must configure the REST source extraction properties.

To do this, you will need to have the “Create Global Objects” permission and provide the query that will help extract data from your data source.

Once you’ve done that, close the REST source and connect it to the ADO.NET-based destination.

Step 4: Configuring the Microsoft SQL Server Database

With all the necessary configurations now done, you now need to configure your Microsoft SQL Server destination database.

You can do this by providing the database name, tables, and information about the desired data access mode and choosing between views/tables.

Now, map the incoming data with the destination column and then click on the advanced option and specify the following properties:

  • BulkInsertFireTriggers: Should bulk insert fire triggers on destination tables.
  • BulkInsertOrder: Sort columns specified in ascending/descending order.
  • MaxInsertCommitSize: Maximum number of rows to insert in a single batch) 
  • DefaultCodePage: Code page to use if the source does not provide one.

You can now execute this workflow to start loading data from REST API to Microsoft SQL Server databases.

This is how you can set up the SQL Server REST API integration using the Microsoft SQL Server Integration Service (SSIS).

Limitations of Using Microsoft SQL Server Integration Services (SSIS)

Some of the limitations of using Microsoft SQL Server Integration Services (SSIS) for SQL Server REST API Integration include:

  • The Microsoft SQL Server Integration Service (SSIS) provides support only for the Microsoft SQL Server database. Hence, if your business data needs require using a diverse set of databases, then using SSIS will not work.
  • If your systems require you to delegate data storage or processing to a particular tool based on the data type, such as MongoDB or Neo4J for graph databases, then SSIS can limit your options.

Method 3: Using Custom Code Snippets to Set Up SQL Server REST API Integration

To start loading data from REST APIs, you must first leverage the JDBC driver’s “DriverManager” class to obtain and establish a connection with your Microsoft SQL Server instance.

You can use the following syntax for creating your connection URL:

protocol//[hosts][/database][?properties] 

Once you’ve set up the necessary configurations and created your connection URL, you need to create a statement object that will carry out SQL operations such as insert, delete, update, etc., and fetch results.

With your statement object ready, you will have to execute the insert command in a repetitive loop based on conditional logic.

Once you’ve executed the insert statement or any other operation, you must close the statement and connection object.

For example, if you want to insert, set, and update values in your Microsoft SQL Server database using APIs, you can do so using the following lines of code:

While (someCondition) {
// Specify the connection URL as per SQL server connection string.
        String connectionUrl = "jdbc:sqlserver://<YourServer>:<port>;databaseName=HevoMSSqlTest;user=<user>;password=<password>";

        try {
//LOAD the API driver 	
	Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
	
//Get a new Connection to SQL Server 
	Connection conn = DriverManager.getConnection(connectionUrl); 

// Create a statement object, this is the vehicle for carrying your SQL inserts				PreparedStatement stmt = conn.prepareStatement("INSERT into my_records" +" VALUES(?,?,?,?,?)");

// SET the values in your table columns 							
	stmt.setInt(1, 0);			
	stmt.setString(2, myString);					
	stmt.setString(3,myAddress);					
	stmt.setString(4, myName);					
	stmt.setString(5, myRole);

//EXECUTE the update 					
	stmt.executeUpdate();
	}// End of TRY block 
	
        catch (Exception e) {
        System.err.println("Error: ");
        e.printStackTrace(System.err); 
        }

	finally {
// CLOSE the Statement and Connection objects 
	stmt.close(); 
	conn.close();    	
	}
} // END of While loop 

This is how you can develop custom code snippets that leverage the JDBC driver for Microsoft SQL Server to set up the SQL Server REST API Integration.

Limitations of Using Custom Code Snippets

Though you can efficiently set up SQL Server REST API Integration manually, several limitations are associated with this method. Some of the limitations include:

  • Using drivers requires keeping track of updates and manually updating them when new releases are available or when your technology stack(Java, Node.js, C++, Python) undergoes updates. Similarly, existing API calls and methods may depreciate with new versions and require upgrades.
  • To ensure smooth data transfers and high efficiencies, you will have to add/remove/change the new properties associated with your connections when any change occurs.
  • Working with APIs to load data requires strong technical knowledge to handle operations such as connection pooling, query optimization, compression, validation, etc.
