get data from sqlite database

[bibhukalyana]

Hi everyone,
I am using qt 4.7 to access sqlite database. In my database one coloum is there whic contains binary data.
My database has 5000 rows.I am using QSqlQuery to exexute query and get data from database.But for 5000 record i have to move in a loop which is time consuming .

query.record().value(0).toByteArray()

query.record().value(0).toByteArray()

To copy to clipboard, switch view to plain text mode 

Plsease tell me a better way so that i can get data within some miliseconds.

Thanks.
