Design rdl report using subreport

This section describes the steps to create SSRS RDL report to compare two different employees details side by side using subreport.

Create a main report

Below is the dataset query used for the main report. Refer Create Data section and create dataset using the below query.
```
SELECT
Employees.EmployeeID,
Employees.FirstName
FROM
Employees
```
To compare the employee details, create two parameters named Employee-A and Employee-B in the main report and assign the required dataset field value to the parameters as shown in the following snaps. Refer Parameter and Assign Value section to create and assign value to the parameters.
Using textbox and line report items, design a simple report as shown below.

Note: Refer Textbox, Line section to design the above report design.

Add subreport

Drag and drop subreport item listed in the item panel under the Sub Reports category.
To compare the employee details, drag and drop two subreport items side by side in the design area.

Create a subreport

Design a subreport to display the employee details.

Create dataset

Below is the dataset query used in this report to fetch the employee personal details that is bound to the Employees table of Northwind database. Refer Create Data section and create dataset using the below query.

SELECT Employees.EmployeeID,Employees.LastName,Employees.FirstName,Employees.Title,Employees.TitleOfCourtesy ,(DATENAME(WEEKDAY,Employees.BirthDate)+', '+ DATENAME (DAY,Employees.BirthDate)+'+DATENAME(MONTH,Employees.BirthDate)+'+DATENAME(YEAR,Employees.BirthDate)) as BirthDate
,(DATENAME(WEEKDAY,Employees.HireDate)+', '+DATENAME(DAY,Employees.HireDate)+'+DATENAME(MONTH,Employees.HireDate)+'+DATENAME(YEAR,Employees.HireDate))as HireDate
,Employees.HomePhone ,Employees.City,Employees.Region,Employees.PostalCode,Employees.Country ,SUM(o.Quantity * o.UnitPrice)  As TotalGain FROM
Employees,[Order Details] as O,[Orders] as Ord  WHERE o.OrderID  = ord.OrderID and Employees.EmployeeID = ord.EmployeeID and Employees.EmployeeID = @SalesPersonID
group by  Employees.EmployeeID ,Employees.LastName,Employees.FirstName,Employees.Title,Employees.TitleOfCourtesy,BirthDate,HireDate,Employees.City,Employees.HomePhone,Employees.Region
,Employees.PostalCode,Employees.Country

To present respective employee sales order details information in the tabular format, create a dataset using below query and bind data to the table report item.

SELECT Top(10) o.OrderID,Cus.CompanyName,SUM(OD.UnitPrice * od.Quantity ) As ExPrice FROM [Orders] as O, [Customers] as Cus,[Order Details] as OD where  (O.EmployeeID = @SalesPersonID) and (cus.CustomerID=o.CustomerID) and od.OrderID = o.OrderID group by o.OrderID,o.CustomerID,cus.CompanyName

Use the below query and create a dataset, to retrieve the employee image details from Employees table of Northwind database.
```
SELECT Employees.Photo FROM Employees
WHERE (Employees.EmployeeID = @SalesPersonID)
```
Now, the dataset created in the report will be listed in the Data panel as shown below.
Based on the @SalesPersonID query parameter created in dataset query, equivalent report parameter will be created automatically in the report as shown below.

Design report

Here we have designed a simple subreport using image, textbox and table reportitem as shown below. subreport item with properties view

Note: Refer Image, Line, Table section to design the above subreport.

Assign fields

To display employee DOB, we have used this =First(Fields!BirthDate.Value,"EmployeePersonalDetails") expression in the textbox reportitem.
To display employee DOJ, we have used this =First(Fields!HireDate.Value,"EmployeePersonalDetails") expression in the textbox reportitem.
To display employee GAIN we have used this =Sum(Fields!TotalGain.Value,"EmployeePersonalDetails") expression in the textbox reportitem.
To display employee First Name and Last Name, we have used this =First(Fields!FirstName.Value, "EmployeePersonalDetails")+" "+" "+First(Fields!LastName.Value, "EmployeePersonalDetails") expression in the textbox reportitem.
To present the sales details of a respective employee, EmployeeSalesDetails dataset is assigned to the table report item.
To display employee image in the report, assigned the =First(Fields!Photo.Value, "EmployeeImages") expression to the image report item value property.
