How to Use Conditional Split in SSIS
The SQL Server Integration Services (SSIS) is a powerful tool used for data integration and transformation. One of its many features is the Conditional Split, which allows you to route data rows based on certain conditions. In this article, we will discuss how to use the Conditional Split in SSIS to efficiently route data based on your requirements.
Firstly, to use the Conditional Split in SSIS, you need to have a package loaded in the SSIS Designer. Once you have a package open, follow these steps to add a Conditional Split:
1. Drag and drop a Conditional Split transformation from the SSIS Toolbox onto the Control Flow design surface.
2. Connect the input source to the Conditional Split by dragging and dropping a data flow task from the Toolbox onto the design surface, and then connecting the output of the data flow task to the input of the Conditional Split.
3. Double-click on the Conditional Split to open its editor.
In the Conditional Split editor, you will see the following sections:
– Conditional Split Transformation Editor: This is the main section where you define the conditions for splitting the data.
– Conditions: This section lists all the conditions you have defined. You can add, edit, or delete conditions here.
– Mappings: This section lists the output paths for each condition. You can add, edit, or delete mappings here.
To define a condition, follow these steps:
1. Click the “Add” button in the Conditions section.
2. In the Condition Editor, specify the column and operator for the condition. For example, you can set the condition to be “Column1 = ‘Value1′”.
3. Click “OK” to save the condition.
Once you have defined a condition, you need to specify the output path for that condition. To do this:
1. Click the “Add” button in the Mappings section.
2. In the Mapping Editor, select the condition you want to map to an output path.
3. Choose the output path you want to use for that condition. For example, you can map “Column1 = ‘Value1′” to “Output1”.
4. Click “OK” to save the mapping.
After you have defined all the conditions and mappings, you can run the package to see how the data is split based on the conditions. The Conditional Split will route data rows to the appropriate output path based on the defined conditions.
In summary, using the Conditional Split in SSIS is a straightforward process that involves defining conditions and mappings. By utilizing this feature, you can efficiently route data rows based on your specific requirements, making your SSIS packages more powerful and flexible.
