I have a typical requirement.
I have a flat file which is a fixed length one.
In this flat file from 3rd position to 21st position (i.e 19 characters) is allocated for the acc #. The acc # may not be of full length. The length can vary from 10-19 characters. the data fields are fixed. if the account number doesn't fill all the 19 positions then you will have blanks.
Hope this clarify my problem in more detail

Now my requirement is that I need to replace this acc # in such a way that leaving the first 6 digits and last 4 digits the remaining digits should be 0.

xx5734567893333333 xxxx

xx123456000008738 xxxxx
xx5734560000003333 xxxxx

Thanks to all for help

Does not substr function fit your requirement?
