Answer / prasanna
if ur sources are flat files then you cannot give any SQ
override queries.
to join 2 flatfile sources you need to have a joiner
transformation.
If ur target is a flat file, the loading process is very
fast as its a bulk load where there will be no constraints
( no checks)
You can have number and char data types... but for dates,
you need to convert explicitly
many more diff are there...
You can use indirect method and use many flatfiles of same
structure and load to a target using one session and
workflow tasks.
