Error on Xcode 4.3.2 <Attempt to write a readonly database>

I am new on iphone programming.. I keep getting the error and I have no idea how to change the permission for SQLite

Error while updating. attempt to write a readonly database

and the following is my coding

NSString *filePath = [[NSBundle mainBundle]pathForResource:@"card" ofType:@"sqlite"];
sqlite3_stmt *statement;

if(sqlite3_open([filePath UTF8String], &db) == SQLITE_OK)
{
  const char *query_stmt = "UPDATE card SET isActivate =?";
  if(sqlite3_prepare_v2(db, query_stmt, -1, &statement, NULL) != SQLITE_OK)
     {
         NSAssert1(0, @"Error while creating update statement. '%s'", sqlite3_errmsg(db));
     }
}


sqlite3_bind_int(statement, 1, 1);
if(SQLITE_DONE != sqlite3_step(statement))
   {
      NSLog(@"Error while updating. %s", sqlite3_errmsg(db));
    }

sqlite3_finalize(statement);
sqlite3_close(db);

Hope someone could help me because this really makes me feel frustrated..

You need to copy your sql file to your cache directory in order to use it correctly.
Here's some of my code:

NSString *sqlFile = @"database.sql";
NSArray *cachePath= NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *cacheDir = [cachePathobjectAtIndex:0];
databasePath = [cacheDirstringByAppendingPathComponent:sqlFile];

NSFileManager *fileManager = [NSFileManager defaultManager];
// Copy the database sql file from the resourcepath to the documentpath
if (![fileManager fileExistsAtPath:databasePath]) {
    NSString *databasePathFromApp = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:sqlFile];
    NSError *error;
    [fileManager copyItemAtPath:databasePathFromApp toPath:databasePath error:&error];
    if (error != nil) {
        NSLog(@"[Database:Error] %@", error);
    }
}
