Difference Between Stored Procedure and Functions Sql

Stored Procedure and Functions

 

1. Function Must Return Value

   For Stored Procedure it's Not Must to return value it's optional 

2. Stored Procedures are pre-compile objects which are compiled for 

first time and its compiled format is saved which executes (compiled code) whenever it is called 

But Function is compiled and executed every time when it is called

3. Function can Accept only Input Parameters

   But Stored Procedure Can Accept Both Input and Output Parameters

4. Functions can be called from Procedure whereas Procedures cannot be called from Function

5. Functions Like Views only Accept Data Select Statements It does not Allow the Permanent Storage of data so it does not allows DML statements like Insert , Update , Delete

Whereas Store Procedure Allows All type of DML statements like Insert , Update and also Select Statements.

6. Funtions can be used in Select Statements like views to View data 

But Stored Procedure Cannot be Embedded in Select Statements

7.

 

Difference Between Views And StoredProcedure Sql

Stored Procedure Vs Views

1. Stored Procedure are collection of pre-executed sql Statements that accepts parameters as input and depending on input parameters passed gives the Output Result

Views Act like Virtual Tables That Contains set of Rows and Columns from multiple original table of Database according to defined Query Commands

2. Stored Procedure Cannot be Used as Large Building Block or we can simply say It cannot be treated as tables in large queries 

But Views Can be treated like tables we can Use Views similar to table and execute select statements on Views Similar to Tables

3. Stored Procedures Allow the Use of Data Manipulation Command like Insert Data , Update data on Table or Schemas To Manipulate Data

But Views Cannot have Data Manipulation Command It can only give list of data or View of data based on set of Queries in it . Views cannot be used to Permanently store data in database it allows just to view the data.

4. Views  can have  only one Select Statement Allowed To Use

Store Procedure Can Use Various Set of Statements That also Include If-Else Statements

5. View is a virtual table that only exists when you use the view in a query. Its considered virtual table because it acts like a table, and the same operations that can be performed on a table can be performed on a view. Virtual table doesn't stay in the database, it gets created when we use the view and then delete it. 

But Stored Procedure Physically Exist 

6. Views are Used for Providing Security to data So that by using the Views we can View only Particular view of the schema to the user Not the Full View with required columns. Their is no physical presence of view data anywhere in database.

Stored Procedure allows to perform any type of data Manipulation operation But We can also Put Security Permission on Store Procedure In order to Restrict its Access From Unauthorized User

7. Code Sample For Stored Procedure and Views

/*
This Stored procedure is used to Insert value into the table tbl_students. 
*/

Create Procedure InsertStudentrecord
(
 @StudentFirstName Varchar(200),
 @StudentLastName  Varchar(200),
 @StudentEmail     Varchar(50)
) 
As
 Begin
   Insert into tbl_Students (Firstname, lastname, Email)
   Values(@StudentFirstName, @StudentLastName,@StudentEmail)
 End

/*

View Example

*/

CREATE VIEW [Category Sales For 1997] AS

SELECT DISTINCT CategoryName,Sum(ProductSales) AS CategorySales

FROM [Product Sales for 1997]

GROUP BY CategoryName

Using Report Viewer with Dataset Asp.net Csharp and vb

For Using Report Viewer in Asp.net or Desktop Application using Csharp or Visual basic I am today providing a simple step by step solution -

Demo File is also available to Download so that you can have a demo for how to use or Use Reports With Dataset in Asp.net . I have provided Both Csharp and Vb code

Step 1 - First of Start a C# Project or Vb Project and then Add an Empty Webform to it .

Step 2 :- Now Right Click on Solution in Solution Explorer and Click on Add then click on New Item . Then Click On DataSet and Give a Name and Click Ok . This will add a Dataset in your Project . I will recommend it give dataset a name similar to database table whose data you want to show in Report Viewer

 Step 7 :- Now Open your Recently Added Report file you will see it same as shown below

Using Report Viewer with Dataset Asp.net Csharp and vb , Using Reporting in asp .net dotnet

Step 8 :- Now we need to Add the Previously added dataset or need to link the dataset we added in previous steps to the report file

Step 9 :- So for that linking Right Click on Dataaset folder in sidebar of Report Then Click on Add Dataset then you will see the following screen

Step 10 :- Now select the Added Dataset from Combox for DataSource and then after that Choose the DataTable from Next Last Combobox

Step 13:-  Now we need to Add the Code so Open Cshar Code side of Webpage where you have added the Report viewer control And Add the following code according to your choose language c# or vb

Now At Page_Load Event of your WebPage Add the Following Code According to C# or VB


Imports System.Data
Imports System.Data.SqlClient
Imports Microsoft.Reporting.WebForms

        'VB CODE
        ReportViewer1.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Local
        ReportViewer1.LocalReport.ReportPath = Server.MapPath("~/Report.rdlc")

        Dim dsUsersInfo As New DataSet1
        Dim con As New SqlConnection("Your Connection String")
        Dim cmd As New SqlCommand("select * from YourTableName", con)
        Dim da As New SqlDataAdapter()
        da.SelectCommand = cmd

        'DataTable1 is the DataTable we have created in Dataset1 that contains our columns
        da.Fill(dsUsersInfo, "DataTable1")


        Dim datasource As New ReportDataSource("DataSet1", dsUsersInfo)
        ReportViewer1.LocalReport.DataSources.Clear()
        ReportViewer1.LocalReport.DataSources.Add(datasource)


        'CSharp Code
        'ReportViewer1.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Local
        'ReportViewer1.LocalReport.ReportPath = Server.MapPath("~/Report.rdlc")

        ' DataSet1 dsUsersInfo = new DataSet1();

        '        SqlConnection con = new SqlConnection("Your Connection String"));

        '            con.Open();
        '            SqlCommand cmd1 = new SqlCommand("select * from TableName", con);

        '            SqlDataAdapter da = new SqlDataAdapter(cmd1);
        '            da.Fill(dsUsersInfo, "DataTable1");
        '            con.Close();

        '        ReportDataSource datasource = new ReportDataSource("DataSet1", dsUsersInfo.Tables[0]);

        'ReportViewer1.LocalReport.DataSources.Clear()
        'ReportViewer1.LocalReport.DataSources.Add(datasource)




Step 12 :- Now when you run the Page where you have added the Report viewer control It will show the Report with data from database

Parse Error The base class includes the field ‘reportViewer’, but its type (Microsoft.Reporting.WebForms.ReportViewer) is not compatible with the type of control (Microsoft.Reporting.WebForms

Parse Error Message:the base class include the field 'reportviewer1',but its type (Microsoft.reporting.webforms.reportviewer) is not compatible with the type of control (Microsoft.reporting.webforms.reportviewer)

This Error Occur due to Usage of different version of ReportViewer in Same .Net Project . It may happen when you have referenced a different version of ReportViewer dll files as compared to Version of Report Viewer dll ReportViewer Control is using and referenced in web.config file

So we need have same version of Report Viewer dll file in web.config file that matches with Control using and as well as version that we have referenced .

So Dll File we are using is - Microsoft.Reporting.WebForms .

Fix For This Error - 

Go to your web.config file and Search for following code -

    <add path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" validate="false"/>

YOU CAN SEE VERSION IN ABOVE CODE "VERSION=10.0.0.0" OR IT MAY BE 11.0.0.0 OR BELOW 10 .SO WE NEED TO MAKE REFERENCE TO SAME ASSEMBLY IN ORDER TO MATCH THE VERSION OF ASSEMBLY REFERENCED WITH CONTROL USING ASSEBLY
SO HERE CONTROL IS USING 10.0.0.0 VERSION OF ASSEMBLY

STEP FOR FIX Parse Error 

1. Right Click on your Website or WebApplication in Solution Explorer

2. Then Click on Add Reference 

3. Then Search For Reporting

4. Then Checkmark the Checkbox for Microsoft.ReportViewer.WebForms with Same Version  10.0.0.0 or other that is available in your web.config

5. Now Click ok 

6. Rebuild Your Solution and Now Error Should be Resolved
