How to fix `no such table` error with SQLite

I had to search for many posts regarding these errors, but still I cannot fix the problem. Here is my code, can anyone help me to see what is going wrong?

- (void) copyDatabaseIfNeeded {
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *path = [documentsDirectory stringByAppendingPathComponent:@"SQL.sqlite"];
    
    if (sqlite3_open([path UTF8String], &newDBconnection) == SQLITE_OK) {
        NSLog(@"Database opened successfully");
        
        if(updateStmt == nil) {
            NSString *updStmt = [NSString stringWithFormat: @"UPDATE Coffee SET CoffeeName = '500 Plus', Price = '1.40' Where CoffeeID= '3'"];
            const char *mupdate_stmt = [updStmt UTF8String]; 
            
            if(sqlite3_prepare_v2(newDBconnection, mupdate_stmt, -1, &updateStmt, NULL) != SQLITE_OK){
                NSAssert1(0, @"Error while creating update statement. '%s'", sqlite3_errmsg(newDBconnection));
            } else {
                NSLog(@"Update successful");
            }
        }

        if(SQLITE_DONE != sqlite3_step(updateStmt))
            NSAssert1(0, @"Error while updating. '%s'", sqlite3_errmsg(newDBconnection));
        else {
            sqlite3_reset(updateStmt);
            NSLog(@"Step successful");
        }
    } else {
        NSLog(@"Error in opening database  ");
    }
}

There is no table Coffee in SQL.sqlite.

SQLite silently creates the database file if it does not exist. So if you've got the path wrong, you are opening an empty database file, which of course does not contain any tables. Make sure the database file exists there and it is not empty.

You can see what tables are there in the database by running SELECT * FROM sqlite_master; query.
