I am trying to call a stored procedure using Dapper.Net
and get return values.
p.Add("@INCIDENT_ID", dbType: DbType.Int32, direction: ParameterDirection.ReturnValue);
var retResults = con.Execute("usp_GetIncidentID", p, commandType:CommandType.StoredProcedure);
int IncidentID = p.Get<int>("INCIDENT_ID");
I have tried a couple of different things with the parameter direction and using the "@INCIDENT_ID"
. If you step through the results, you can see that the proper return values are coming down in the retResults
value, but I am not able to access the values the way it is described in the documentation as below..
Stored Procedures Dapper supports fully stored procs:
var user = cnn.Query<User>("spGetUser", new {Id = 1},
commandType: CommandType.StoredProcedure).First();}}}
If you want something more fancy, you can do:
var p = new DynamicParameters();
p.Add("@a", 11);
p.Add("@b", dbType: DbType.Int32, direction: ParameterDirection.Output);
p.Add("@c", dbType: DbType.Int32, direction: ParameterDirection.ReturnValue);
cnn.Execute("spMagicProc", p, commandType: commandType.StoredProcedure);
int b = p.Get<int>("@b");
int c = p.Get<int>("@c");
You can read the value as below
var incidentId = retResults.ToList()[0].INCIDENT_ID;
I suspect (untested) that this is purely a mismatch in how you name the parameter; try (note the removed @
):
p.Add("INCIDENT_ID", dbType: DbType.Int32, direction: ParameterDirection.ReturnValue);
var retResults = con.Execute("usp_GetIncidentID", p, commandType:CommandType.StoredProcedure);
int IncidentID = p.Get<int>("INCIDENT_ID");
