create 3 files

hi

i have 1 stored proc , i am creating excel file from it

now the output contains all total amount and other data.

i need to create 3 files from 1 excel file based on 2 dates, but i dont want to create 3 proc for that and also i cannot have

startdate and todate parameter in stored proc.

whats is other way , but just creating 3 output ,entring 1 date and split into 3 files
