Get Multiple Results from Stored Procedure using Dapper in C#, VB.NET

Feb 18, 2015

Here I will explain how to get multiple results or records from stored procedure using dapper in
c#, or access multiple results or objects from stored procedure in dapper using querymultiple method in c#,

In previous articles I explained
start or stop IIS service in c#,, get values from ienumerable list in c#,, jQuery upload images without postback in, wcf tutorial for beginners with example in and many articles relating to AngularJS, jQuery,, c# and Now I will explain how to get multiple results or records from stored procedure using dapper in c#,

To get multiple results from stored procedure using dapper we need to use querymultiple method that would be like as shown

C# Code

using (IDbConnection conn = new SqlConnection(connectionString))
IEnumerable<dynamic> results = conn.Query(sql: storedProcedureName,param: parameters,commandType: CommandType.StoredProcedure);
var reader = conn.QueryMultiple(storedProcedureName, parameters, commandType: CommandType.StoredProcedure);
var userdetails = reader.Read<userdetails>().ToList();
var salarydetails = reader.Read<salraydetails>().ToList();

public class userdetails
public int userid;
public string username;
public class salraydetails
public int salary;
public int empid;


Using conn As IDbConnection = New SqlConnection(connectionString)
Dim results As IEnumerable(Of Dynamic) = conn.Query(sql:=storedProcedureName, param:=parameters, commandType:=CommandType.StoredProcedure)
Dim reader = conn.QueryMultiple(storedProcedureName, parameters, commandType:=CommandType.StoredProcedure)
Dim userdetails = reader.Read(Of userdetails)().ToList()
Dim salarydetails = reader.Read(Of salraydetails)().ToList()
End Using

Public Class userdetails
Public userid As Integer
Public username As String
End Class
Public Class salraydetails
Public salary As Integer
Public empid As Integer
End Class
