SQL Scripts used in Demo:
CREATE
TABLE SALES(
YEAR VARCHAR2(4) ,
Q1 NUMBER(10,2) ,
Q2 NUMBER(10,2) ,
Q3 NUMBER(10,2) ,
Q4 NUMBER(10,2) );
/
CREATE
TABLE SALES_PER_QUARTER(
YEAR
VARCHAR2(4),
QUARTER
VARCHAR2(2),
SALES
NUMBER(10,2));
/
INSERT
INTO SALES VALUES('2014',23345.32,32456.41,21234.21,18324.12);
INSERT
INTO SALES VALUES('2015',24324.12,34234.51,25345.18,17234.86);
COMMIT;

Scenario
In this
scenario, we are converting rows into columns.
Implementing
un-pivot component which is available in ODI 12c (which will be available from
12.1.3 version onwards) in ODI 11g
Process:
1. Create model
2. Create Reverse engineer above mention
datastores
3. Create new interface
4. Drag and drop Source datastore
(SALES) and Target Datastore (SALES_PER_QUARTER)
As mention below and map accordingly.
5. Click on “highlighted” dataset symbol
(in the above diagram) which will pop-up for datasets creation.
6. Create four datasets for four
quarters as below.
7. Now interface looks as follows
8. For Quarter2 –Quarter Column ‘Q2’ and
Sales Column <Q2_Value>
Similarly we need to repeat for Quarter3 and Quarter4
9. Make sure that Quarter mapping should
be “Staging”
10. Select appropriate knowledge as per
your requirement (In this case I am selecting IKM SQL Control Append) and flow
control as “false” (because I don’t have any key on target side)
11. Execute it.
