For each loop container where  data comes from multiple columns in select from a SQL table

I need to create an SSIS package that will create  files  where the file name contains the Date and time of all rows  that are selected from a SQL table.  I gather that I need to use a foreach loop container, and I Have three variables that hold Dte:  '1/2/2014' which is the date from the input table,  Hr:  15 which contains the hour of the day and Portion: 1 or 2 which designates if the activity occurred in the first half hour (1) or the second half hour.  
Do I need to generate a for each loop that for each Date then within that for each loop the hour of the day, then a third for each loop that designates the half hour or can I do I all in one For each loop?  

Can someone give me an idea of how to proceed?

Thanks
