Creating job in sql server which automates taking backup of all stored procedures and functions in physical drive.

Introduction

Many times as a developer of administrator we need to take a backup of database stored procedures and function to physical drive as many users changes many procedures and at a time we need previous unchanged procedures (We take backup of schema only when database has large amount of data).  So here is the solution how your daily tedious task can go smooth with below job. 

Background

This job will perform database(s) procedures backup to physical drive and let user edit and view it and replace it if required.

Default path to export procedure, it takes as C:\Backup\StoredProcedure\ (if folder is not created then it will automatically create it).

In this folder it will created date and time wise folder, e.g., 2012.11.23_15.43.44 that indicates 23rd november 2012 with 15:43 hours. this indicates when backup has taken so folder is on date and time.

In this folder, there will have different folders as per number of databases in server and in each folder it will take a backup of particular stored procedure of that databases. 

Please find below code or find attached file which creates job and by executing this job it will start taking backup of stored procedures as well as functions on physical drive. Like this:

USE [msdb]
GO
