IF 2 SOURCES ARE RELATIONAL USE SQ T/R
WRITE MANUVAL QUERY
first connect requrired 16+1 attributes to furter t/r or target
select required columns and in where condition write matched condition
if there is no common column go to joiner create sequence in both sources then compare sequence in join vondition

Hi All, i have question regarding Change Data Capture in Informatica. As i know we can do this using Incremental Aggregation(i never worked on Informatica but i read) and i think we can do the same with SQL Over write and with variables. Can someone tell me how do we do this using other two techniques.. using SQL Over write and variables. Thanks for the help and greatly appreciated.
I have 4 columns in a table say, name ,address, salary and city. So based on distinct city names, i need to combine the other data and send it to a flat file. Distinct city names can be 4 or 5 or 6. So it has to dynamically generate flat files(4 or 5 or 6) corresponding to the city names.
Are there any types of Dynamic Caches in informatica
