using the folowing extention methods :



    public static void SetParameters(this IQuery query, List<object> Parameters) {
for (int i = 0; i < Parameters.Count(); i++) {
query.SetParameter(i, Parameters[i]);
}
}
public static IQuery SetQuery(this ISession session, string Query, object Parameters) {
return session.CreateSQLQuery(Query + string.Empty + "(" + ParseExt(Parameters) + ")");
}

private static string ParseExt(object Parameters) {
var str = new List<string>();
for (int i = 0; i < Parameters.Length; i++) {
str.Add(":" + i);
}
return string.Join(",", str);
}


i'm creating a query :




  • public IEnumerable<T> Execute<T>(string Query, params dynamic Parameters) {
    using (var _session = _transactionManager.GetSession()) {
    var _cmd = _session.SetQuery(Query, Parameters);
    if (Parameters != null) {
    _cmd.SetParameters(Parameters.ToList());
    }
    return _cmd.List<T>();
    }
    }


throws the following error :



Remember that ordinal parameters are 1-based!


NOTE : i tried to change the index to start from 1

The symbol for position-parameter is not :xxx but ?.



This change will work



private static string ParseExt(object Parameters) {
var str = new List<string>();
for (int i = 0; i < Parameters.Length; i++) {
//str.Add(":" + i);
str.Add("?"); // + i);
}
return string.Join(",", str);
}
