Multiples rows to single row

Can Consider both source and target as flatfiles or any relational source/target

Source

emp_name,emp_id  

siva,101 

sundar,101 

kumar,101 

satya,102 

lokesh,102

narra,102

Target

EmpID,FullName

101,Siva Sundar Kumar

102,Satya Lokesh Narra

Transform each row in to levels based on the the hierarchy id column

Consider source and target as flat files

Source:

child#  parent# hier#

1       2               10

2       3               10

3       4               10

4                       10

1       2               20

2                       20

1       2              30

2       3              30

3                       30

Target:

Lvl1   Lvl2   Lvl3   Lvl4

4       3       2       1

2       1

3       2       1

Case 1

Here maximum we have 4 levels

Case 2

We don't know the number of level(Hint:- Try to use JAVA transformation to find the Maximum level), means a for each hierarchy number(heir#) we can have n numbers of levels

What is an Inline View

The concept of using subquery in the FROM clause of SELECT statement is called inline view

Example:-
 SELECT T1.Col1, T1.Col2, T2.Col1
FROM Table1 T1,(SELECT col1,AVG(col2) FROM Table1 GROUP BY Col2) T2
WHERE T1.Col1 = T2.Col1

Informatica server start and stops immedietly

Problem 1

TOAD for oracle 11g 64 Bit Installation in Windows 7

While Installing oracle 11g R2 in windows 7 64 bit Operating system
better to go for Oracle 11g 32 bit only so that TOAD will support for 32bit
Oracle only
