SQL Server Create and Execute Parameterized Stored Procedure From Another Stored Procedure

Introduction

In this article am going to explain how to create and execute parameterized stored procedure From another stored procedure, how to prevent Sql Injection attacks, how to Insert data in table using stored procedure in Sql Server with example. And also show you how you can use procedure in SQL Server with example.

Sql Server Stored Procedure

When You working with any data driven application you need database and also need some data manipulation operations in DBMS(Database Management System) such as selection, insertion, updation, deletion and etc.

Your database may contains some useful and confidential information so it is necessary to protect it from any unauthorized activity and implement some security credentials with your DBMS(Database Management System) for secure your data from unauthorized activity.

If you working with sql server then stored procedure is one of the best option for data manipulation operations, because stored procedure accept parameter as argument, and parameterized statements prevent code injection technique such as "SQL Injection" that might destroy your database.

So, Hear i will show you how you can use stored procedure in your sql server database.

Requirement

1) Insert data in table using stored procedure.

2) Create Stored Procedure in Sql Server.

3) Call or Execute Stored Procedure in SQL Server.

4) Call or Execute Stored Procedure From Another Stored Procedure in SQL Server.

5) Select and Display Inserted Data in Tabular Format in SQL Server Using Stored Procedure.

Implementation

Before, start our actual implementation of our example we need database for demonstration, So first we will create database.

Create Database

CREATE DATABASE db_Codingvila

Before create stored procedure i will show you the syntax of stored procedure in SQL Server.

Syntax

CREATE PROCEDURE Your_Procedure_Name
-- list of parameters i.g: @Id INT = 0, @EmpName VARCHAR(50)=''
AS
BEGIN
-- Sql statements
END

Now, we will start to write our stored procedure something like :

Create First Stored Procedure

--****************************************
-- CREATED ON 20/11/2018 BY NIKUNJ SATAIYA
--****************************************
 
-- Create First Stored Procedure
 
CREATE PROCEDURE Employee_Insert
@EmpId INT, 
@EmpName VARCHAR(50),
@EmpDesignation  VARCHAR(50)
AS
BEGIN
-- Declare temporary table
 
DECLARE @Temp1 TABLE (EmployeeId INT, EmployeeName VARCHAR(50), EmployeeDesignation VARCHAR(50))
 
-- insert records in temporary table
 
INSERT INTO @temp1 (EmployeeId, EmployeeName, EmployeeDesignation)
     VALUES(1,'Nikunj Satasiya','Software Engineer'),
     (2,'Hiren Dobariya','Web Developer'),
     (3,'Vivek Ghadiya','Business Development Executive'),
     (4,'Pratik Pansuriya','Business Development Executive'),
     (5,'Milan Lathiya','Software Engineer')
     
-- Select all records from temporary table    
SELECT EmployeeId, EmployeeName, EmployeeDesignation FROM @Temp1
-- Select specific records from temporary table
SELECT EmployeeId, EmployeeName, EmployeeDesignation FROM @Temp1 WHERE EmployeeId = @EmpId AND EmployeeName = @EmpName AND EmployeeDesignation = @EmpDesignation
 
END

If You analyzed Above procedure then you can see @EmpId, @EmpName and @EmpDesignation where @ can described as a parameter.

Now, i will show you how to create second stored procedure and how you can insert data in table using first created stored procedure, and for that i used temporary table.

Create Second Stored Procedure

Now it's time to call/Execute created stored procedure and insert data in table and also display result in tabular format, for that here we will create another stored procedure and will call/Execute created stored procedure.

--****************************************
-- CREATED ON 20/11/2018 BY NIKUNJ SATAIYA
--****************************************
 
-- Create Second Stored Procedure
 
CREATE PROCEDURE Employee_GetData
@Id INT, 
@Name VARCHAR(50),
@Designation  VARCHAR(50)
AS
BEGIN
-- Execute First Procedure
EXECUTE Employee_Insert @EmpId = @Id , @EmpName = @Name, @EmpDesignation = @Designation
 
END

Again If You analyzed Above procedure then you can see our First created stored procedure is execute with "EXEC" You also can use "EXECUTE" also, where @Id, @Name and @Designation sending parameters to first stored procedure.

--Execute Second Procedure By Passing Paramters
EXEC Employee_GetData @id=1, @name='Nikunj Satasiya', @Designation ='Software Engineer'

Now we will call/Execute our second created procedure that will call/Execute our first created procedure with actual result as per our requirement.

After successful execution of this procedure you can see result as like shown in output window.

Output
