Now, I got it like this:

PHP Code:

    new id = Data[0]
    new flags[32], output[1024]

    if ( SQL_NumResults(Query) )
    {
        while( SQL_MoreResults( Query ) )
        {
            new qcolAccess = SQL_FieldNameToNum( Query, "access" )
            SQL_ReadResult( Query, qcolAccess, flags, 31 )
            add( output, sizeof(output), flags, sizeof(flags) )
            SQL_NextRow(Query)
        }
    }

    SQL_FreeHandle(g_SqlTuple)

    set_task( 0.2, "set_flags", id, output, sizeof(output) );

    return PLUGIN_CONTINUE
}

public set_flags( const flags[], id  )
{
    set_user_flags( id, read_flags( flags ) )
    log_amx( "Set flags: %s to player: #%d", flags, id )
} 


But it still don't set access flags :/ I have logged in console "Set flags: t to player: #1" so it should work...
