Question

I have created sqlite database.

I add this sqlite file in my application but when I run the app in the simulator and check the sqlite file’s path in document directory and I open the sqlite file on document directory’s path at that time the table which I have created does not appear.

In local copy I can see the table also in my project folder I can see the table but on the path of simulator I am not able to see the table

so in my console it shows me the error:

Sqlite Prepare failed: no such table

Answer 1

My response below assumes that your database is properly formatted and functional. You could test easily via the command line. In my own apps, all tab bar controllers apps, I place the db access code in the app delegate. The two methods in the app delegate are as follows:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions (NSDictionary *)launchOptions {
    [self createEditableCopyOfDatabaseIfNeeded];
    [self.window setRootViewController:rootController]; 
    [window makeKeyAndVisible];
    return YES;
}

Also:

- (void)createEditableCopyOfDatabaseIfNeeded {

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDir = [paths objectAtIndex:0];

    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSError *error;
    NSString *dbPath =[documentsDir stringByAppendingPathComponent:@"dbName.sqlite"];
    BOOL success = [fileManager fileExistsAtPath:dbPath];
    if(!success)
    {
        NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"dbName.sqlite"];
        success = [fileManager copyItemAtPath:defaultDBPath toPath:dbPath error:&error];

        if (!success)
            NSAssert1(0, @"Failed to create writable database file with message '%@'.", [error localizedDescription]);
    }
}
