Stored Procedure in Orchard - sql

Question

Hi We are working on a project and i am trying to call a stored procedure. I have searched for the solution but i didn't find any way that how to call a stored procedure so can any one please tell me how to execute stored procedure.

Answer 1

How ever finally i am using the below code to execute the stored procedure and get the result.
using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Suppress))
{
// temporary scope for new connection and setting stored procedure, parameters, and return RecordName list
using (SqlConnection cn = new SqlConnection(_settingsManager.LoadSettings().First().DataConnectionString))
{
if (cn.State == ConnectionState.Closed)
{
cn.Open();
}
const string storedProcedure = "usp_spName";
SqlCommand cmd = new SqlCommand(storedProcedure, cn);
cmd.Parameters.AddWithValue("#IsVerified", "value");
cmd.Parameters.AddWithValue("#page", "value");
// for out put parameter
cmd.Parameters.AddWithValue("#totalRows", 0);
cmd.Parameters["#totalRows"].Direction = ParameterDirection.Output;
cmd.CommandType = CommandType.StoredProcedure;
IDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
// To Get The Values of the result
int id=Convert.ToInt32(reader["Id"].ToString());
}
reader.Close();
try
{
// To Get the Out Put Perameter
totalRecords = (int)cmd.Parameters["#totalRows"].Value;
}
catch
{
totalRecords = 0;
}
cmd.Parameters.Clear();
cmd.Dispose();
cn.Close();
}
}

actually, I don't know about stored procedures, but you can call stored functions using code like examaple below. I'm new to C# and orchard, so may be my approach is not correct and good enough. At first you should get ISessionLocator object instance, using IOrchardServices, then create NHibernate ISession instance and then IQuery/ISQLQuery with CreateSQLQuery().
here is example code of Services class
public class ExampleService {
private readonly IOrchardServices _oServices;
public EParamsServices(IOrchardServices oServices) {
_oServices = oServices;
}
public float GetRegionPopulationDencity(int rId){
//resolve ISession locator (you can do this using dependencies in ctor)
ISessionLocator sl = _oServices.WorkContext.Resolve<ISessionLocator>();
//create session
ISession _session = sl.For(null);
// create raw SQL query
return _session.CreateSQLQuery(#"SELECT data.RegionDencity(:rId) as result")
.AddScalar("result", NHibernateUtil.Single)
.SetParameter<int>("rId", rId)
.List<float>()
.FirstOrDefault<float>();
}
}
I think you can exec stored procs the same way, just change SQL code do exec yourProcName and ExecuteUpdate() instead of List() method (I'm not sure in this part)
you also should add reference to NHibernate assembly to your project and add NHibernate & Orchard.Data to your using part.

You have to reference NHibernate and System.Data in your module , then you can use the below code
var cmd = _transactionManager.GetSession().Connection.CreateCommand();
cmd.CommandType = System.Data.CommandType.StoredProcedure;
cmd.CommandText = "MyStoredProcedure";
_transactionManager.GetSession().Transaction.Enlist(cmd);
cmd.ExecuteNonQuery();
