hi Rob,

What exactly i wanted to do is..

to take a input from a file of format :

INPUT.txt :

Details> name , id INTEGER, area VARCHAR(32)
prady,2039,india
sandy,2398,india
sam,1234,aussie
Rob,2345,Eng
extraDetails>name1 VARCHAR(12), name2 VARCHAR(12)
prady,sandy
sandy,Rob
Rob,sam
sam,prady


in the above text format u can find two tables one is Details> & the other
is extraDetails>

so i wanted to take the line Details> for creating table , & the values
below it for inserting into the table. similarly the second shud be find out
(extraDetails) & those values shud be inserted in to its table

& one more script the other way round like by getting the (retrieving) the
data from the mysql database using some queries & creating a file in the
above specified INPUT.txt format.

could u please help me in this regard
thanx
Regards
Prady
