Problem with the flat file
Hi All,
I have a situation where I have a flat file that contains data that needs to be loaded into tables. The flat file contains 10 columns that are pipe dilimited. This table contains more than 500,000 rows.
This flat file was created from two different sources. The problem is third column(10 digit character) got switched with the fourth column(three digit character) somewhere in the middle of the flatfile i.e. somewhere in the file the fourth column became the third column and vice versa. This probably happened when the data from two sources are merged. Due to some problem I am not able to generate the file again.
I am trying to put all the rows with three digit character in fourth column into one file and ten digit character rows in another file. Is there a unix script/command that I can use to divide this file into two different file so that I can load all data sucessfully.
I will really appreciate any help in this regards.
Thanks
Raj
