I am trying to insert values in database but while preparing statement it is giving me error "SQL error or missing database"...can anyone know what this error is and how one can resolve this?????my path for database is

2010-07-22 14:34:59.933 DatabaseApp[1521:207] path of database /Users/nuzhat/Library/Application Support/iPhone Simulator/User/Applications/C50A0188-2A9A-487F-951C-6E7FFCE3CFBB/Documents/UserName.db3

here is my code:- // Open the database connection and retrieve minimal information for all objects. - (void)initializeDatabase {

//for second database
NSString *path1 = [documentsDirectory stringByAppendingPathComponent:@"UserName.db3"];


// Open the database. The database was prepared outside the application.
if (sqlite3_open([path UTF8String], &database) == SQLITE_OK) 
{
    // Get the primary key for all books.
    const char *sql = "SELECT CountryName FROM Country";

    sqlite3_stmt *statement = nil;
    // Preparing a statement compiles the SQL query into a byte-code program in the SQLite library.
    // The third parameter is either the length of the SQL string or -1 to read up to the first null terminator.

thanks in advance....

Not enough information here, but I think it could be a couple of things. Does the user of the database you are using have the permissions that allow them to insert data to the database? You might want to append your post so it includes the SQL statement you are using.
