( #3333=superdoc: print w/ replies, xml ) Need Help??

Hi all,

currently i have doubt regarding how to merge two big files and 1 config files. the 1st files is around 20 Mils records and 2nd one is 400K and 1 config files around 50 records.

due to this, need your help whether we can use perl (using hash) for merging files or using sql database (pl sql) to make it faster.

logic :

1. get the 1st, 4th and 6th columns from file 1

2. compare the 4th and 6th columns with config files for the mapping

3. if the mapping is found from 2nd step, compare with file2 by :

a. comparing the 1st column on file1 and 2nd column on file2

b. comparing the 2nd column from config file and 1st column on file2

4. merge into new files by :

a. replacing the 4th column on file1 with 1st column on config file

b. replacing 6th column on file1 with 5th column on config file

c. add the 3rd & 4th column from file2
