Question

I need to change the pragma options to this. How should I do it? Where do i need to use this command? And how do i use it?

PRAGMA default_synchronous = OFF;

Answer 1

PRAGMA is an SQL command. Just execute it like you would do with any other command, such as INSERT.

(Please note that SQLite simply ignores unknown PRAGMAs; the statement you've shown will have no effect.)
