TL;DR

This can be done by building a data pipeline manually, usually a Python script (you can leverage a tool as Apache Airflow for this). This process can take more than a full week of development. Or it can be done in minutes on Airbyte in three easy steps:

1. set up Microsoft SQL Server (MSSQL) as a source connector (using Auth, or usually an API key)
2. set up Teradata as a destination connector
3. define which data you want to transfer and how frequently

You can choose to self-host the pipeline using Airbyte Open Source or have it managed for you with Airbyte Cloud.

This tutorial’s purpose is to show you how.

Prerequisites

1. A Microsoft SQL Server (MSSQL) account to transfer your customer data automatically from.
2. A Teradata account.
3. An active Airbyte Cloud account, or you can also choose to use Airbyte Open Source locally. You can follow the instructions to set up Airbyte on your system using docker-compose.

Airbyte is an open-source data integration platform that consolidates and streamlines the process of extracting and loading data from multiple data sources to data warehouses. It offers pre-built connectors, including Microsoft SQL Server (MSSQL) and Teradata, for seamless data migration.

When using Airbyte to move data from Microsoft SQL Server (MSSQL) to Teradata, it extracts data from Microsoft SQL Server (MSSQL) using the source connector, converts it into a format Teradata can ingest using the provided schema, and then loads it into Teradata via the destination connector. This allows businesses to leverage their Microsoft SQL Server (MSSQL) data for advanced analytics and insights within Teradata, simplifying the ETL process and saving significant time and resources.

Methods to Move Data From Microsoft sql server to teradata

• Method 1: Connecting Microsoft sql server to teradata using Airbyte.

Method 2: Connecting Microsoft sql server to teradata manually

Moving data from Microsoft SQL Server to Teradata without using third-party connectors or integrations can be accomplished through a series of steps involving exporting data from SQL Server into a flat file and then loading it into Teradata using its native load utilities. Below is a detailed step-by-step guide to accomplish this task:

Step 1: Prepare the Data for Export in SQL Server

1. Identify the Data: Determine which tables or data sets you need to transfer from SQL Server to Teradata.

2. Data Cleanup: Ensure that the data is clean, consistent, and conforms to the data types and constraints in Teradata.

3. Create Scripts: Write SQL scripts to select the data you want to export. It's important to consider the correct ordering of columns and data formatting.

Step 2: Export Data from SQL Server

1. Use BCP Utility: The Bulk Copy Program (BCP) is a command-line utility that ships with SQL Server. It can be used to export data efficiently.   

   Example command:

   ```shell

   bcp "SELECT * FROM YourDatabase.dbo.YourTable" queryout "C:\export\data.txt" -c -t"," -S YourServer -U YourUsername -P YourPassword

   ```

2. Choose the Right Data Format: Decide whether to export data in character format (-c) or native format (-n). Character format is generally more compatible.

3. Specify Column Delimiter: Use the `-t` option to specify a field terminator, such as a comma for CSV format.

4. Handle Special Characters: Ensure that any special characters or delimiters within the data are appropriately handled or escaped.

Step 3: Prepare Teradata Environment

1. Create Tables: Define the schema in Teradata to match the data being imported. Make sure all tables and columns are correctly defined.

2. Set Permissions: Ensure that the user account you’ll be using has the necessary permissions to create tables and insert data.

Step 4: Transfer the Data File

1. Move the File: Transfer the exported flat file to a location accessible by the Teradata system.

2. Secure the Data: Ensure that the data transfer is secure, especially if it contains sensitive information.

Step 5: Load Data into Teradata

1. Use Teradata Load Utilities: Teradata provides several utilities for loading data, such as FastLoad, MultiLoad, or Teradata Parallel Transporter (TPT). Choose the one that best fits your data volume and structure.   

2. Prepare Load Scripts: Write the control file or scripts required by the chosen utility, specifying source data file location, data format, error handling, and target table.

   Example for FastLoad:

   ```sql

   LOGON your_teradata_server/your_username,your_password;

   BEGIN LOADING YourDatabase.YourTable

   ERRORFILES YourDatabase.Err1, YourDatabase.Err2;   

   DEFINE

   Column1 (CHAR(100)),

   Column2 (CHAR(100)),

   -- Define all columns as per the source file format

   FILE = your_data_file;

   INSERT INTO YourDatabase.YourTable

   VALUES

   (

   :Column1,

   :Column2,

   -- Map all columns

   );

   END LOADING;

   LOGOFF;

   ```

3. Execute Load Script: Run the load script using the Teradata utility command-line interface.

Step 6: Verify Data Integrity

1. Check Load Summary: Review the logs and output of the load utility to ensure that the load process completed successfully without errors.

2. Sample Data Queries: Run some queries against the loaded data in Teradata to verify that the data looks correct.

3. Data Quality Checks: Perform any necessary data quality checks to ensure the integrity of the data.

Step 7: Post-Load Cleanup

1. Archive or Delete Flat File: Once the data is successfully loaded into Teradata, archive or securely delete the flat file if it's no longer needed.

2. Optimize Teradata Tables: Collect statistics on the new tables to optimize query performance.

3. Document the Process: Keep a record of the steps taken and any scripts used for future reference or recurring data transfers.

‍Additional Notes

- While this process does not use third-party connectors, it does require the use of native utilities provided by SQL Server and Teradata.

- Always test the process with a small subset of data before attempting a full-scale data migration.

- Consider data types and character sets compatibility between SQL Server and Teradata to avoid data corruption or loss.

- Make sure to comply with any data governance or compliance requirements during the data transfer process.
