problem in reading image from data base in iphone

hi i am able to store the image into database by using the following code.......

-(void)insertimages: (NSData *)image
{
    if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK)
    {
        NSUInteger len = [image length];
        NSLog(@"data size is %d", len);

        sqlStatement="insert into messages values(10,?)";
        if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK)
        {
            //sqlite3_bind_int(compiledStatement, 1, -1);
            //sqlite3_bind_blob(updateStmt, 3, [imgData bytes], [imgData length], NULL);
            sqlite3_bind_blob(compiledStatement, 1, [image bytes], [image length], SQLITE_TRANSIENT);
            //sqlite3_bind_text(compiledStatement, 1, [SMSBody UTF8String],-1,SQLITE_STATIC);
            if(sqlite3_step(compiledStatement) == SQLITE_DONE) 
            {
                sqlite3_finalize(compiledStatement);                
            }

        }

I was trying to do this a year ago, I wrote code to save the images into a sqlite3 db using osx sdk (of which i was able to write and read, i could even store the images in the db with ruby and read them on with macosx sdk). But when i moved this exact code over to an iOS app it would pull out bad data. If you do work this out i'd like to know the answer.

Use following method to read the image data from database and stored the images in array or in dictionary


-(void) readImageDataFromDatabase {
    // Setup the database object
    sqlite3 *database;

    // Init the img Array
    imageArray = [[NSMutableArray alloc] init];

    // Open the database from the users filessytem
    if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK) {
        // Setup the SQL Statement and compile it for faster access
        const char *sqlStatement = "select * from messages";
        sqlite3_stmt *compiledStatement;
        if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) {
            // Loop through the results and add them to the feeds array
            while(sqlite3_step(compiledStatement) == SQLITE_ROW) {
                // Read the data from the result row
                NSURL *url = [NSURL URLWithString:[NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 1)]];
];
                NSData *imgData = [NSData dataWithContentsOfURL: url];

                // Create a new image object with the data from the database
                iconImage.image=[UIImage imageWithData:imgData];

                // Add the img object to the img Array
                [imageArray addObject:iconImage];
            }
        }
        // Release the compiled statement from memory
        sqlite3_finalize(compiledStatement);

    }
    sqlite3_close(database);

}
