Hi!

I have a table with, let´s say, 4 columns, person, colA, col B and colC.

The first column contains personal number (ssn) so when I export data to outside persons I dont want to send also the actual value in column.  Instead I want to replace, in this case "760320" with "1" and 760914 with "2".  Please note that 760320 and other personal numbers can occure 1, 2 or several times.


person      col A          col B            col C
760320      x          y                       z
760320      x          y                       z
760914      x          y                       u

The result should be

person  col A colB       col C
1             x      y           z
1             x      y           z
2             x      y            u


Thanks in advance

>>when I export data to outside

Do you mean Oracle Export?

Hi!

Thanks for really fast possible solutions.

sdstuber: I will try your solution at work tomorrow.

slightwv: I wrote export, but the only import thing is really to get the result from the select-query in SQL developer . From there I can choose to copy the rows from the select or right click  to export. Sorry if this caused false focus.

Are you only wanting a single table or will you be exporting additional related tables and need to keep the obfuscated values equal across the exports?
