Control Flow Tasks in SSIS
This section provides tutorials on using various Control Flow tasks within SQL Server Integration Services (SSIS) to build powerful data integration and transformation workflows.
Understanding Control Flow
The Control Flow defines the overall structure and execution logic of an SSIS package. It orchestrates the sequence, constraints, and precedence of tasks that perform data extraction, transformation, loading, and administrative operations.
Common Control Flow Tasks
Explore the following tutorials to learn about key Control Flow tasks:
Execute SQL Task
Learn how to execute Transact-SQL statements or stored procedures directly from your SSIS package.
Data Flow Task
Understand how to configure and use the Data Flow task, which is the core component for data transformation and manipulation.
Send Mail Task
Discover how to send email notifications as part of your package's execution flow, useful for alerts and reporting.
File System Task
Learn to automate file operations such as copying, moving, deleting, or renaming files and folders.
For Loop Container
Master the use of For Loop containers to iterate over a set of tasks based on a specified condition.
Foreach Loop Container
Explore how to iterate over a collection of objects, such as files in a folder or rows in a table, using the Foreach Loop container.
Sequence Container
Understand how to group related tasks logically and manage their execution as a unit using Sequence containers.
Precedence Constraints
Learn how to define the flow of execution between tasks using different types of precedence constraints:
- Success Constraint: Executes the next task only if the preceding task succeeds.
- Failure Constraint: Executes the next task only if the preceding task fails.
- Completion Constraint: Executes the next task regardless of whether the preceding task succeeded or failed.
- Expression Constraint: Executes the next task based on the evaluation of a specified expression.
Variables and Parameters
Discover how to use variables and parameters to make your control flow dynamic and reusable.
By mastering these control flow tasks and concepts, you can build robust and efficient SSIS solutions for your data integration needs.
