Hi,
I have DB2 table having 2 cols, in One column the values are like this
Code:

col1                      col2
--------               -----------
xxxxxx               abc**hy
yyyyyy               hyted#&by


My requirment is to find all the records having junk value in col2 and replace those by spaces.

Output of the query will be
Code:

col1                      col2
--------               -----------
xxxxxx               abc  hy
yyyyyy               hyted  by


( please note *, # is not the junk value. some hex value other than zero is junk value)

batu544,

Define Junk values. Show the actual junk value in hex. How many of them do you have?

Set up a TRANSLATE function with the hex values you want to replace. Using the characters in your example, &, *, and #, the TRANSLATE would look like this:

Code:
translate(COL2,'   ',x'505C7B')


Just expand the list to include all the values that you want to replace.

Take a look at this post too.
