SCENARIO 1: TAKE THE BACKUP OF THE TABLE USING SOURCE QUALIFIER TRANSFORMATION
Source Table: EMP
Table
Target Table: Emp_Bkp
CREATE TABLE EMP_BKP AS SELECT * FROM EMP WHERE 1=2;
Check: SELECT COUN FROM EMP_BKP;
Soln:
Ø In
Source Analyzer, import the EMP table
Ø Create
a Table similar to Emp Table structure in database.
Ø Now in
target designer import emp_bkp table.
Ø In
mapping designer, create a new mapping drag and drop the source , target table
structure and Map it.
Ø Save
it.
Ø Now
goto the Workflow manager, create a Flow and Task.
Ø Assign

SCENARIO: 2 – SPLITTING NON KEY
COLUMN TO SEPARATE TABLE WITH KEY COLUMN IN BOTH.
Source Table:
SRC_2
Target Table: TGT_2A, TGT_2B
Ø Drag and Drop the source and target tables in Mapping
designer
Ø In Mapping designer, to the Source Qualifier connect an
aggregator with key column to be grouped.
-Ø Now to split Non key column add 2 Expression Tf with Key Column each.
-Ø Now to split Non key column add 2 Expression Tf with Key Column each.
-Ø To the Expression transformation add set of Aggregator
transformation and group by the Key Column.
