running stored procedures into own model with servicestack ormlite - servicestack

Question

Is there any examples to be found for running a stored procedure on serviceStack MVC using ormlite? mythz ? seen this block of code:
var results = new List<EnergyCompare>
{dbFactory.Exec(dbCmd =>
{
dbCmd.CommandType = CommandType.StoredProcedure;
dbCmd.Parameters.Add(new SqlParameter("#id", 1));
dbCmd.CommandText = "GetAuthorById";
return dbCmd.ExecuteReader().ConvertTo<EnergyCompare>();
}
)};
but came with the text of never worked on the google groups!
i can also write this:
using(var db = new SwitchWizardDb())
{
var results2 = db.dbCmd.ExecuteProcedure()
}
but not sure how to complete this with parameters, and in the source code I looked at, it said obsolete?
thanks

Looks like ServiceStack.ORMLite has been updated to make this easier:
List<Poco> results = db.SqlList<Poco>("EXEC GetAnalyticsForWeek 1");
List<Poco> results = db.SqlList<Poco>("EXEC GetAnalyticsForWeek #weekNo", new { weekNo = 1 });
List<int> results = db.SqlList<int>("EXEC GetTotalsForWeek 1");
List<int> results = db.SqlList<int>("EXEC GetTotalsForWeek #weekNo", new { weekNo = 1 });
This example is on the front page of the github repo.

Well I figured it was best to roll my own handler so have created this, any thoughts would be most welcome, especially with how I could pass over params in some kind of func or something:
I have a main class to deal with easy access to my connection object:
public class DatabaseNameSp : IDisposable
{
private readonly SqlConnection _spConn = new SqlConnection(DatabaseNameSp .dbConString);
public readonly SqlCommand SpCmd;
public DatabaseNameSp (string procedureName)
{
_spConn.Open();
SpCmd = new SqlCommand
{
Connection = _spConn,
CommandType = CommandType.StoredProcedure,
CommandText = procedureName
};
}
public void Dispose()
{
_spConn.Close();
SpCmd.Dispose();
}
}
usage:
using (var db = new DatabaseNameSp ("procedurenname"))
{
db.SpCmd.Parameters.Add(new SqlParameter("#Id", 1));
var rdr = db.SpCmd.ExecuteReader(CommandBehavior.CloseConnection);
var results = new List<CustomDTO>();
while (rdr.Read())
{
results.Add(new CustomDTO { Name = rdr["name"].ToString(), Id = rdr["id"].ToString() });
}
return new CustomDTOResponse { Results = results };
}
Any thoughts !
thanks

Here is an example of running a stored procedure with ormLite that may help you:
IList<MyDTO> myList = DbFactory.Run(dbCnx =>
{
using (var dbCmd = dbCnx.CreateCommand())
{
dbCmd.CommandType = CommandType.StoredProcedure;
dbCmd.CommandText = "mySchema.myStoredProc";
dbCmd.Parameters.Add(new SqlParameter("#param1", val1));
dbCmd.Parameters.Add(new SqlParameter("#param2", val2));
var r = dbCmd.ExecuteReader();
return r.ConvertToList<MyDTO>();
}
});

To just simply run a stored procedure with no data returned:
public class ComsManager : Dbase
{
private IDbConnection dbConn;
public ComsManager()
{
dbConn = Dbase.GetConnection();
}
public void Housekeeping()
{
using(var dbCmd = dbConn.CreateCommand())
dbConn.Exec(res => { dbCmd.CommandType = CommandType.StoredProcedure; dbCmd.CommandText = "SP_housekeeping"; dbCmd.ExecuteNonQuery(); });
}
