Answer / babu

Hi Sbvprasad,
Your answer has small correction,

V1=iif(not isnull (id),id,v1)

for the 1st record.
V1= iif( not isnull (101), then pass 101).
now the V1 variable having the value = 101.

2nd record
V1= iif( not isnull ( null), then pass else condition V1 (
having 101 ))
now the V1 variable having the value = 101.

3rd record
V1= iif( not isnull ( null), then pass else condition V1 (
having 101 ))
now the V1 variable having the value = 101.

After applied the above logic we will get the output as
mentioned below.
-------------
ID NAME
--- ------
101 PANKAJ
101 KUMAR
101 MATHUR
102 JYOTI
102 SAXENA
103 SACHIN
102 TENDULKAR

2.Take an EXP t/r,in this t/r declare two variable ports
for ID and Name columns.those are PRV_ID and VAR_NAME

VAR_NAME=IIF(PRV_ID=ID,VAR_NAME||' '||NAME,NAME)
PRV_ID=ID
OP_NAME=VAR_NAME (OUTPUT PORT)

3.In the next step take the aggregator transformation and
group by on the ID COLUMN. Then you will get the result.

TARGET TABLE
-------------
ID NAME
--- -------
101 PANKAJ KUMAR MATHUR
102 JYOTI SAXENA
103 SACHIN TENDULKAR

MAPPING ::
---------

SRC-->SQ-->EXP-->EXP-->AGGR-->TRG
IF ANY THING WRONG, PLEASE CORRECT WITH PROPER SOLUTION.

Answer / nagraj

From SQ pass to Expression Transformation

- Take Variable for ID i.e.
V_ID =iif(not isnull(ID),ID ,V_ID )
- Take Variable for Name i.e.
iif( isnull(ID) ,CONCAT(CONCAT(LTRIM(RTRIM
(V_old_Name)),' ') ,Name),Name)

At this stage you will see the Data like this
ID Name
101 PANKAJ
101 PANKAL KUMAR
101 PANKAJ KUMAR MATHUR

Now pass the ID and NAME output port through an Aggregator
Transformation
-Take new variable for Name i.e.
New_Name=concat(concat(New_Name,' '),Name)
-Take new output port for Name and put expression for the
Name output port as follows
Out_Name=GREATEST(Name,New_Name)
- Check Group By on ID

Pass the ID and Name outpurt port to the Target.

option (truncate and load)



Where Group by on ID port

Answer / user

just take a variable port

then write the condition
decode(id,null,prev_id,id)

prev_id =id(it should be a variable port)

i m just giving an idea

Answer / sbvprasad

V1=iif(not isnull (id),id,v1)

for the 1st record.
V1= iif( not isnull (101), then pass 101).
now the V1 variable having the value = 101.

2nd record
V1= iif( not isnull ( null), then pass else condition V1 (
having 101 ))
now the V1 variable having the value = 101.

3rd record
V1= iif( not isnull ( null), then pass else condition V1 (
having 101 ))
now the V1 variable having the value = 101.

After applied the above logic we will get the output as
mentioned below.
-------------
ID NAME
--- ------
101 PANKAJ
101 KUMAR
101 MATHUR
102 JYOTI
102 SAXENA
103 SACHIN
102 TENDULKAR

2.In the next step take the aggregator transformation and
group by on the id. Then you will get the result.

TARGET TABLE
-------------
ID NAME
--- -------
101 PANKAJ KUMAR MATHUR
102 JYOTI SAXENA
103 SACHIN TENDULKAR
