Splitting flat file rows to multiple flat files SSIS

Question

I'm fairly new to SSIS and I'm having a bit of a problem splitting a CSV into multiple files by row.

I have a CSV with multiple rows - I am trying to split each row into a new flat file and make each column a new line in the flat file.

I currently have a flat file source pumping into a derived column and sorting the data into the format I want. To test this I outputted it into 1 large flat file with multiple rows however I would ideally like to create a file for each row.

I have tried using a for each to loop through but I'm not quite sure how to use it in SSIS.

Any help would be appreciated - Thanks in advance.

Answer 1

I think you don't need a loop, a C# script will do the trick. With blocks defined as:

Source -> [RowCounter into variable Counter] -> [Script Task] -> Destination

Script Task:

int val = Convert.ToInt32(Dts.Variables["Counter"].Value);
Dts.Connections["destinationConnectionName"].ConnectionString = "c:\\yourpath\\" + val.ToString() + ".txt";

of course you have to specify readonly parameter: Counter.

This will set the connection name for each row. Combine it with sorting, which you already have.

Answer 2

You can use the Multicast Transformation in a Data Flow to send each record derived from your Flat File Source to two or more Flat File Destinations. This may be a more efficient way to use SSIS than using a loop container or a script task.
