Hi Siva,
Something like
TableNames:
SQL SELECT NAME
FROM SYSTABLES;
Will give you a resident table giving you all the table names in your database. If you want to save the tables to qvd you will need to loop through the tablenames and create a qvd for each one - a qvd holds one table only.
This script to loop through the tablenames could be like below. I haven't tested this and wrote it in a hurry so I suggest caution - start off with For i =1 to 1 or some other low number. It gives the gist of how to do it.
For i = 1 to NoOfRows('TableNames')
Let TN = Peek('NAME',$(i),'TableNames');
[$(TN)]:
LOAD*;
SQL SELECT *
FROM $(TN);
STORE [$(TN)] into $(TN).qvd (qvd);
Next
