1 Basic Database Operation Using SSMS Mr. Hrishikesh Belgamwar 1, Prof. S.L.Thombare 2 1 Student, I.T. Department, J.D.I.E.T, Yavatmal, hrishibelgamwar@gmail.com 2 Assistant Professor, I.T. Department, J.D.I.E.T, Yavatmal, satishthombare@gmail.com ABSTRACT- In today s world, database sizes everywhere are growing with high speed. Many applications / systems has Tera bytes to Pico bytes of data. It is challenging to support and maintain such huge database. Every year companies spend big money to maintain their Database servers and hire professional DBAs. Getting skilled and expert DBA has been always challenging for the organizations. On the other-hand, it has been equally difficult for the IT professionals to learn and get all the DBA skills under his belt. Most of the DBA learn the required skills on job or the companies have to provide them through training. It costs lot of money and time. Understanding the practical difficulties faced by the companies and the stiff learning challenges for the Fresh IT Graduate, we came up with idea of helping newbie DBAs to quickly learn the essential DBA skills and become a Pro-DBA. This Paper helps DBA to perform like a gem and produce Specific, Measurable, Accurate, Reliable, and Time-bound solutions. Write the underneath SQL commands of that operation in the textbox. And relevant description in brief. This will help the DBA in learning things for doing it SMARTly. Keywords: DBA, Reliable, Time-Bound 1. INTRODUCTION In this Paper Contain the Various type of DBA Activities i.e. Create, Drop, Attach - Detach, Online - Offline, Shrink and Server Explorer all this types are use in this paper. How to performed the operation in SQL Server Management Studio this is write in this paper. Two ways of performing activity are as follows :- 1) Using GUI ( Graphical User Interface ) 2) Using T - SQL (Transact SQL Script ) 1) Using GUI :- In that type contain step of activity perform and the snapshots are also available. For going this way in SQL Server Management Studio and performed the activity. 2) Using T-SQL :- In this type write the SQL query of all operation included in this Paper i.e. Create, Drop, Attach - Detach, Online - Offline, Shrink. if write this query in window of sql server then executed and completed the operation Successfully. Using this Paper DBA doing work of SMARTly i.e. Specific, Measurable, accurate, Reliable, and Time -Allocation Understanding the practical difficulties faced by the companies and the stiff learning challenges for the Fresh IT. Graduate, we came up with idea of helping newbie DBAs to quickly learn the essential DBA skills and become a Pro - DBA. 2. CREATE DATABASE Create Database for using storing data in table in rows and column, as well as database contain views, function. In one SQL Server Management Studio Database is created. Creating database it is recommended to create data file and log file under different drive as well as same drive also. Usually the datafile is of bigger size than log file. In SQL Server Management studio Databases is created using two ways. 203

2 A) Using Graphical User Interface :- Steps of Creating Database are as follows:- Step1: Right click on Databases Step2: Select New Database Step3: Mention Database name, path, size, maxsize, file growth Step 4: Press Ok B) Create Database Using T-SQL Script :- Create database Databasename primary on ( name=databasename.mdf, Filename = 'C:\\Databasename_Data.mdf', size = <size> MB, maxsize = <size>mb, Filegrowth = 10% ) logon ( name= Databasename.ldf, Filename = 'C:\\Databasename_Log.ldf', size = <size> MB, maxsize = <size> MB, Filegrowth = 10% ) 3. ONLINE / OFFLINE DATABASE :- Database is made offline to move its physical files. Database Offline means it is not available for users, it is not deleted physically it can be brought back online. If Database is offline and need this database that time online the database using GUI or T-SQL Script. A) Online the database by using GUI : A) Offline the database by using GUI : Step3: Click on Tasks Step4:Click on Bring Online Step3: Click on Tasks Step4:Click on Take Offline 204

3 B) Online the database by using Script : Alter database <Database_name> Set online B) Offline the database by using Script : Alter database <Database_name> Set offline with rollback immediate 4. DROP DATABASE Drop Command is use to all the rows is remove an object from database. It is also make free space and table structure is also remove. Drop Command remove the physical file also. A) Drop the database by using GUI : Step3: Click on Delete B) Drop the database by using T-SQL command : Drop database <Database_name> 5. Attach / Detach DATABASE Attach Database means attach the data file and log file from program files. if any database is delete or drop from SSMS but after that this database is required then do not create database. Directly attach database using T- SQL Script or using GUI. therefore time is also save and less memory required. Detaching removes the registration of the database within SQL Server. After Detaching, the database will be remove from SQL Server but will be intact within data and transaction Log File that compose the database. 205

4 A) Attach the database by using GUI : Step 3: Select Attach Step 4: Add File Step5 : Click Ok A) Detach the database by using GUI : Step 3: Click on Tasks Step 4: Click on Detach Step 5: Check drop and update Step 6: Click on Ok B) Attach the database by using Script : Exec =N' <Database = N'C:\<Database = N'C:\<Database Name>_log.ldf'; B) Detach the database by using Script : Exec sp_detach_db <Database Name> 6. SHRINK DATABASE :- Shrink Databases or data files recovers space by moving pages of data from the end of the file to unoccupied space closer to the front of the file. When enough free space is created at the end of file can be deallocated and returned to the file system. Shrink Database means compress Database or make available free space in MB or Percentage(%). A) Database shrinking by using GUI: Step 1: Select the database Step 2: Right click on it Step 3: Go to task and then click on shrink Step 4: Click on database which you want to shrink Step 5: If you want to shrink database as per your convenience then and number in percentage Step6:Click OK B) Shrink database by using T-SQL: USE [ database_ name] GO DBCC SHRINKDATABASE(N database_name, size in %) GO 206

5 7. BACKUP DATABASE It is full copy of your entire database. Although the full backup provides best protection, most organization used their on a periodic basic because they are time consuming and often require large disk space. Backup Database is use for if in case any disaster is occur like that Harddisk is crash or database is deleted by mistake then that time this backup is restore in SSMS and use the database. In SQL Server Management studio Taking Full Backup of Database by using two ways. A) Full database Backup by using GUI : Step 3: Click on tasks Step 4: Click on Back Up Step 5: Select Database, Backup Type - Differential Step 6 : Select Component - Database, write Path Step 7 : Add destination Path Step 8 : Select Option Page Step 9 : Choose Overwrite Media, Write Media Set Name Step 10: Click on OK B) Full Database Backup By Using T-SQL Script : BACKUP DATABASE Dbname TO DISK= C:\Dbname_Full.Bak Dbname_Full.Bak WITH FORMAT, MEDIANAME= C:\ ; 8. CONCLUSION I Conclude that during the study of DBA i found that various type operations on database. In this paper i have explained only 5-6 operation on database with Using GUI i.e. Graphical User Interface and T- SQL Script in SQL Server Management Studio. This paper is very useful to newbie student of dba for understanding the basic database operation with GUI step as well as query. i hope so this is very beneficial to all the student.
