Reading & Writing to File with qt3.3.4 , Please help me in detail

Good Morning Guys

I have a big problem with the year ending process . ie; at the financial year ending time we are planning to create a new database [ in postgresql ] by renaming the old - database .
In the old-database i have a table called tbl_stock_on_hand ,from which we can indentify Each Products Current-Stock .

My problem is to transfere this Current-Stock of Individual Product from Old-Database to the New database as OPENING STOCK to individual items

How it is possible ...........? please help me it's very urgent

Just dump the data to a file and then load it to the new database or use dblink function.

And how are these related to reading and writing using a file? If you ask specific questions, you'll get specific answers. For a general question of yours I can give you a general answer -- use QFile class.

Answer for next level questions - use QSqlDatabase :)

Please, don't start multiple threads on the same problem.
