Summary  
This chapter explains how to configure a pipeline activity to execute pre-defined SQL commands for tasks such as schema modification, data type casting, and table transformation.  

General domain of usage  
ETL pipelines

The **Script Activity** in Azure Data Factory is a powerful tool that allows you to execute SQL scripts as part of your data pipelines. This feature is particularly useful for tasks such as managing database schemas, performing updates, or running any custom SQL commands needed to prepare or manage your data infrastructure.

Unlike the Copy Activity, which is focused on moving data, the Script Activity is designed to **modify, update, or interact with the database itself**. It is commonly used in scenarios such as adding or removing columns, creating or dropping tables, or applying business rules through stored procedures.

## How to Use Script Activity  

1. Start by dragging the **Script Activity** from the Activities pane onto the pipeline canvas in Azure Data Factory Studio; 
2. Link the Script Activity to your database by selecting a pre-configured **Linked Service**;
3. Open the **Script** tab and write your SQL commands, such as creating, modifying, or dropping database objects; 
4. Validate the pipeline.  

How does the Script Activity differ from the Copy Activity in Azure Data Factory?
