Save image data to sqlite database in iphone

Here is how you can Save image to SQLITE:

// Create Images Table.
sql_stmp = "CREATE TABLE IF NOT EXISTS IMAGES (URL TEXT UNIQUE, IMAGE BLOB)";
if( sqlite3_exec(articlesDB, sql_stmp, NULL, NULL, &errMsg) != SQLITE_OK )
    NSLog( @"Fail to create \"IMAGES\" table. Error is: %@", errMsg );

And Here is function for save:

// Save Small Image Data by given main url 
- (void) SaveImagesToSql: (NSData*) imgData :(NSString*) mainUrl
{
    NSLog( @"\n*****Save image to SQLite*****\n" );

    const char* sqliteQuery = "INSERT INTO IMAGES (URL, IMAGE) VALUES (?, ?)";
    sqlite3_stmt* statement;

    if( sqlite3_prepare_v2(articlesDB, sqliteQuery, -1, &statement, NULL) == SQLITE_OK )
    {
        sqlite3_bind_text(statement, 1, [mainUrl UTF8String], -1, SQLITE_TRANSIENT);
        sqlite3_bind_blob(statement, 2, [imgData bytes], [imgData length], SQLITE_TRANSIENT);
        sqlite3_step(statement);
    }
    else NSLog( @"SaveBody: Failed from sqlite3_prepare_v2. Error is:  %s", sqlite3_errmsg(articlesDB) );

    // Finalize and close database.
    sqlite3_finalize(statement);
}

And here is function to load images:

// Load images from data base with given image url 
- (NSData*) LoadImagesFromSql: (NSString*) imageLink
{
    NSData* data = nil;
    NSString* sqliteQuery = [NSString stringWithFormat:@"SELECT IMAGE FROM IMAGES WHERE URL = '%@'", imageLink];    
    sqlite3_stmt* statement;

    if( sqlite3_prepare_v2(articlesDB, [sqliteQuery UTF8String], -1, &statement, NULL) == SQLITE_OK )
    {
        if( sqlite3_step(statement) == SQLITE_ROW )
        {
            int length = sqlite3_column_bytes(statement, 0);
            data       = [NSData dataWithBytes:sqlite3_column_blob(statement, 0) length:length];
        }
    }

    // Finalize and close database.
    sqlite3_finalize(statement);

    return data;

}
