How to handle data set having multiple tables in Dotnet core using Fromsql()
.net .net-core asp.net asp.net-core-webapi entity-framework-core
Question
I am creating WebApi using dot net core
I have created procedure which returns data from 2 tables AS:-
select * from table1
select * from table2
I have model list as:-
public class ModelList
{
public model1 m1 { get; set; }
public model2 m2 { get; set; }
}
i am executing procedure and receiving result in mode list as:-
List<ModelList> ML= new List<ModelList>();
ML= db.ModelList.FromSql("EXECUTE [dbo].[usp]").ToList();
I am not getting the result of those two tables in these two separate objects.
it works with single table but not with multiple.
please suggest where i am making mistake ?
or whether it is doable in dot net core ?

The following implementation will provide the desired result:
public ModelList ExecuteMultiple(string query){
using( IDbConnection connection = new SqlConnection(YOUR_CONNECTION_STRING)){
try{
connection.Open();
var multi = connection.QueryMultiple(query);
var modelList = new ModelList();
modelList.m1 = multi.Read<model1>();
modelList.m2 = multi.Read<model2>();
return modelList;
}
catch( Exception ex){
Console.WriteLine(ex.Message);
}finally{
connection.Close();
}
}
return null;
}
Usage:
var modelList = ExecuteMultiple("EXECUTE [dbo].[usp]");
