url not getting inserted in SQLite3 database

Question

Hi All,

i'm trying to insert the url links in the SQLite3 database but its crashing does any one have any idea ... y its happening ?

if i statically trying to insert any url, it works but dynamically when i get urls of navigated web pages.... they do not insert.... please suggest me how to make it work. I'm using SDK 3.2

this is my insert function:

-(BOOL)insertImageToDB:(UIImage *)screenImage forURL:(NSString *)webURL
{
    BOOL retValue=NO;
    sqlite3 *database;
    sqlite3_stmt *insert_statement = nil;

    //NSString *localURL = webURL;

    NSString *localURL = @"https://www.google.com/";

    if (sqlite3_open([[self sqlitePath] UTF8String], &database)==SQLITE_OK)
    {
        const char *sql = "insert into Web_Image (Screen_Image, url) Values (?,?)";
        if (sqlite3_prepare_v2(database, sql, -1, &insert_statement, NULL) == SQLITE_OK) {

            NSData *data = UIImageJPEGRepresentation(screenImage, 0);
            if(data != nil)
            {
                sqlite3_bind_blob(insert_statement, 1, [data bytes], [data length], SQLITE_TRANSIENT);
            }
            else 
            {
                sqlite3_bind_blob(insert_statement, 1, nil, -1 , SQLITE_TRANSIENT);
            }
            sqlite3_bind_text(insert_statement, 2, [localURL UTF8String], -1, SQLITE_TRANSIENT);
            //sqlite3_bind_text(insert_statement, 2, [webURL UTF8String], -1, SQLITE_TRANSIENT);
            if(SQLITE_DONE == sqlite3_step(insert_statement)){
                retValue=YES;
            }
        }
        sqlite3_reset(insert_statement);
        sqlite3_finalize(insert_statement);
        sqlite3_close(database);
    }
    return retValue;
}   

where, screenImage: is the current web page screenshot. webURL: is the url of the current web page.
