Question

I am facing the problem in the fetching the data from the sqlite database.

I try like this but my data is not getting fetched:

+(void) getInitialDataToDisplay:(NSString *)dbPath
{
JourneyAppDelegate *appDelegate = (JourneyAppDelegate*)[[UIApplication sharedApplication]delegate];
if (sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK)
{
    const char *sql = "select JourneyID,JourneyName,LocationName,Description from UserJourney";
    sqlite3_stmt *selectStmt;
    if(sqlite3_prepare_v2(database, sql, -1, &selectStmt, NULL) == SQLITE_OK)
    {
        while (sqlite3_step(selectStmt) == SQLITE_ROW)
        {
            //NSInteger primaryKey = sqlite3_column_int(selectStmt, 0);
            NewJourney *journeyobj = [[NewJourney alloc]init]; 
/**/when my pointer come at this line it goes out of the scope My  journeyobj.journeyname ,journeyobj.journeylocation and journeyobj.journeydescription is not getting the value.**
            journeyobj.journeyname = [NSString stringWithUTF8String:(char*)sqlite3_column_text(selectStmt, 3)];
            journeyobj.journeylocation = [NSString stringWithUTF8String:(char*)sqlite3_column_text(selectStmt, 4)];
            journeyobj.journeydescription = [NSString stringWithUTF8String:(char*)sqlite3_column_text(selectStmt, 5)];
            journeyobj.isDirty = NO;

            [appDelegate.journeyList addObject:journeyobj];
            [journeyobj release];

        }
    }
}
else 
{
    sqlite3_close(database);
}

}

What is the problem??

Thanks in advance

Also, make sure you only ever have one connection to sqlite open at any time in any thread. Multiple connections won’t work.
