Use Conditional Split if you need to separate the data from a source (Flat File, Excel, Table, etc.) into multiple destinations (Flat File, Excel, Table, etc.)
Step 1: Drop a Data Flow Task to the Control Flow
Step 2: Create 4 Flat File Connections. The first flat file is your source. You can use OLE, ODBC, etc.
This second flat file is for my all .txt data
This third flat file is for my all .cs data
This fourth flat file is for my all .aspx data
Step 3: Drop a Flat File Source into the Data Flow
Step 4: Double click on the Flat File Source and establish the connection by selecting your source file.
Step 5: Drop a Conditional Split into the Data Flow. Drag the arrow from the Flat File Source to the Conditional Split.
Step 6: Double click on the Conditional Split and create three conditions.
Step 7: Drop three Flat File Destination onto the Data Flow
Step 8: Drag the arrow from the Conditional Split onto one of the Flat File Destination. An Input Output Selection dialog will popup. Select one of the output.
Repeat this step for all Flat File Destination.
Step 9: Double click on the Flat File Destination and select the connection. Repeat this process to the other two Flat File Destination
Step 10: Run the SSIS package and now you’ll have all three files with specific file types in them.
In this example, I’m using Flat Files but you can use Excel, ODBC, CSV, etc. The process is the same– just the connection setup is different.
