To use a Conditional Split transformation in SSIS, follow these steps:
- Open SQL Server Data Tools (SSDT) and create a new Integration Services project.
- Create a Data Flow Task in the Control Flow of the package.
- Open the Data Flow Task, and drag and drop a source component, such as an OLE DB Source, onto the design surface.
- Connect the source component to a Conditional Split transformation component by dragging an arrow from the source component to the Conditional Split component.
- Double-click on the Conditional Split component to open its editor.
- In the Conditional Split editor, define one or more conditions that evaluate incoming data rows, using expressions that return a Boolean value.
- For each condition, specify an output path and a name that describes the condition.
- Click OK to close the Conditional Split editor.
- Drag and drop destination components, such as an OLE DB Destination, onto the design surface and connect them to the output paths of the Conditional Split component.
- Configure the properties of each component as needed.
- Save and execute the SSIS package.
The Conditional Split transformation allows you to split data rows into multiple output paths based on one or more conditions. You can use the Conditional Split transformation to perform conditional branching within a data flow, such as filtering data rows based on certain criteria or routing data rows to different destinations based on their values.
For example, if you have a data source that contains customer orders, you can use a Conditional Split transformation to split the orders into different categories based on their total value, such as orders with a total value greater than $10,000, orders with a total value between $5,000 and $10,000, and orders with a total value less than $5,000. You can then write each category of orders to a different destination, such as separate tables or databases.
