I have number of data files, lets assume 25 number of them stored in a specific location. Now I want to merge everything in a single master table.
But the catch is the columns have different names with months and the files will be stored every month. I want to change the cloumn name from November-11 Current to 'Month Current' and November-11 Savings to 'Month Savings' for all the files shared till date and going to be in future. Do you have any smart solution to it?
