if i have records like these
(source table)
rowid name
10001 gdgfj
10002 dkdfh
10003 fjfgdhgjk
10001 gfhgdgh
10002 hjkdghkfh
the target table should be like these by using expression
tranformation.
(Target table)
rowid name
10001 gdgfj
10002 dkdfh
10003 fjfgdhgjk

Answer Posted / krishnakanth.ch
First make sure the values are sorted by rowid and passed
to an expression transformaion.Now create a variable port
in the exp. Lets think var1 and make it empty in the
expression .
now compare rowid with var1 by
IIF(VAR1=ROWID,XX||SUBSTR(ROWID,3,3),ROWID)
When the session starts, since initially the var1 is null,
it will be replaced with first rowid. When the second
record is passed, the values will match the required format
of rowid will be passed and remember to pass the value in
the var1 to the next transformation or target.
Hope this will solve.
Please let me if anything is wrong or does not work out.
