installing sql server
Installing SQL Server
  • Do not install SQL Server on a system that is also a domain controller.
  • Disable SQL Server ports on your firewall
  • Use the most secure file system NTFS
  • If possible, put database and transaction log on different physical disks.
  • My preference is not use the SQL Server installation directory for database files and backups.
typical raid installation
Typical Raid Installation


for writes

Put on different drives

for better performance

non raid with separate disks
Non-RAID with Separate Disks
  • If your configuration allows then each of the following should be put on different disks to optimize performance
  • Databases
  • Transaction Logs
  • tempdb
system databases created
System Databases Created

Databases created during an installation

  • Master
    • The master database records all of the system level information for a SQL Server system.
  • Msdb
    • The msdb database is used by SQL Server Agent for scheduling alerts and jobs, and recording operators.
  • Model
    • The model database is used as the template for all databases created on a system.
  • Tempdb
    • Holds all temporary tables and temporary stored procedures. Note order by creates a temporary table in tempdb.
create database using enterprise manager
Create Database using Enterprise Manager

Using tools in Enterprise Manager

  • Select the Run a Wizard from the Tool Bar
    • From the dialog select Database->Create Database Wizard
    • This provides a step by step process. Defaults are presented where available.
  • Right click on databases in the left explorer window and select New Database
    • Under the 3 tabs General, Data Files and Transaction Logs specify the database name, location, and other properties.
    • You will have to enter the correct values for locations, etc.
databases properties
Databases Properties
  • If you want to see details about an existing database right click on the database in the explorer window select Properties
create database ddl
Create Database DDL

USE master




FILENAME ='f:\sqlserverdata\MSSQL\data\MYDB_Data.MDF',




FILENAME ='f:\sqlserverdata\MSSQL\data\MYDB_Data.MDF',




create manage tables with table designer
Create/Manage Tables with Table Designer
  • Provides graphical interface to easily select column data types
  • When making changes automatically handles constraints for you
table designer features
Table Designer Features
  • Set properties for columns
  • Create and manipulate relationships between tables, including choosing primary and foreign keys for the relationship
  • Create and manipulate indexes, primary keys, and unique constraints attached to a table Indexes/Keys
  • Create and manipulate check constraints
  • Changes are not applied until you close the designer
table creation recommendations
Table Creation Recommendations
  • Don’t use spaces in names
  • Always create a primary key
  • Try to avoid NULLs, use default values instead
  • Be careful of names being too long, some tools use the name of table in creating other entities like stored procedures
  • Take into consideration other databases you may want to support when naming tables
  • Some say always create a clustered index (only allowed one per table). My take, “It depends on the situation.”
ddl for creating tables
DDL for Creating Tables

CREATE TABLE [dbo].[Allergies] (

[PatientId] [int] NOT NULL ,

[AllergyId] [int] IDENTITY (1, 1) NOT NULL ,

[Allergen] [varchar] (50) ,

[AllergyResponse] [varchar] (50) ,






ddl for changing a table
DDL for changing a Table
  • Note: can only add one column at a time. New columns are added to the end of the table definition.


ADD EnteredDate datetime NOT NULL

ALTER TABLE [dbo].[Allergies] ADD




) REFERENCES [dbo].[Patients] (




designing configuring security
Designing & Configuring Security
  • Use the Microsoft Baseline Security Analyzer (MBSA). Download from http://www.microsoft.com/technet/security/tools/mbsahome.mspx
  • Install the latest service packs
  • Implement good administrative and development policies
  • Limit privilege level of SQL Server Services
  • Use Windows Authentication Mode for internet
  • Audit connections to SQL Server
audit connections to sql server
Audit connections to SQL Server

Steps required

  • Expand a server group.
  • Right-click a server, and then click Properties.
  • On the Security tab, under Audit Level, click Failure.

You must stop and restart the server for this setting to take effect.

security checklist
Security Checklist
  • Too many members of the sysadmin fixed server role.
  • Blank or trivial passwords.
  • Weak authentication mode.
  • Excessive rights granted to the Administrators group.
  • Incorrect access control lists (ACLs) on SQL Server data directories.
  • Plaintext sa password in setup files.
  • Excessive rights granted to the guest account (If you don’t need it, best to delete it).
  • Improper configuration of the Everyone group, providing access to certain registry keys.
  • Improper configuration of SQL Server service accounts.
  • Missing service packs and security updates.
limit privilege level of sql server services
Limit privilege level of SQL Server Services.
  • SQL Server Engine/MSSQLServer
    • Run as a Windows domain user account with regular user privileges.
  • SQL Server Agent Service/SQLServerAgent
    • Run as a Windows domain user account with regular user privileges. Note may not be able to if VBScripts need special privileges.
importing exporting tables
Importing & Exporting Tables
  • DTS (Data Transformation Services)
    • Preferred method of handling data
    • Most flexible of the methods
  • BCP (Bulk CoPy)
    • Command line utility (import & export)
    • Faster method than DTS for large data sets
  • Bulk Insert (import only)
dts overview
DTS Overview
  • Provides a set of tools that lets you extract, transform, and consolidate data from disparate sources into single or multiple destinations
  • Can use graphical DTS Package Designer to build transformations or can program command line executable packages using DTS object model.
types of backups
Types of Backups

Simple (does not allow transaction log backups)

Operations that are not logged

Bulk load operations

Select Into

Create Index

Text/image operations

Full(allows transaction log backups)

All operations fully logged.

Bulk Logged (allows transaction log backups)

Operations that are not logged

Same as Simple mode

use simple when
Use Simple when
  • Your data is not critical.
  • Losing all transactions since the last full or differential backup is not an issue.
  • Data is derived from other data sources and is easily recreated.
  • Data is static and does not change often.
  • Space is limited to log transactions. (This may be a short-term reason, but not a good long-term reason.)
use bulk logged
Use Bulk Logged
  • Data is critical, but logging large data loads bogs down the system.
  • Most bulk operations are done off hours and do not interfere with normal transaction processing.
  • You need to be able to recover to a point in time.
use full when
Use Full when
  • Data is critical and no data can be lost.
  • You always need the ability to do a point-in-time recovery (transaction logs must also be backed up).
  • Bulk-logged activities are intermixed with normal transaction processing.
  • You are using replication and need the ability to resynchronize all databases involved in replication to a specific point in time.
switching between modes
Switching between modes

What if you want to have Full mode backups but you have a large bulk load data operation??

  • Use the following command
  • Or use Enterprise Manager
when to backup the master database
When to Backup the master database
  • sp_addlogin
  • sp_droplogin
  • Modified system configuration parameters
creating a backup plan
Creating a Backup Plan
  • Enterprise Manager select the “Run a Wizard” tool. Expand Management select Database Maintenace Plan Wizard
selecting databases
Selecting Databases
  • Select the databases you want to backup from the list
set options
Set Options
  • Select options
  • Specify time interval
checking database integrity
Checking database integrity
  • You can optionally check the integrity before backing up the database
  • Additional dialog windows for specifying Tranaction Log backups and historical logs
recovering databases
Recovering Databases

Timeline showing database usage and backup strategy

  • First recover the database backup
  • Apply Transaction Log from 12:00 noon
  • Next apply Transaction Log from 6:00 PM
  • Have to again modify 10 records
restore database tool
Restore Database Tool
  • From Enterprise Manager, select from the Main menu

Tools ->Restore Database

  • Select the database to restore to (Note: you can can pick a different database name to restore to)
restore options
Restore Options
  • Select additional options as needed
  • If loading a database backup created on another system may need to modify path locations
sql server won t start master database corrupted
SQL Server won’t Start!! master database corrupted
  • May have a bad master database to recover
  • Execute rebuildm.exe shown on right to rebuild master database. Located in (installdir)\Microsoft SQL Server\80\Tools\Binn
  • Restore last backup of master
  • Re-attach databases: right click on Databases then All Tasks->Attach Databases…
automating sql server administration
Automating SQL Server Administration

ALERTS (configured in SQL Agent)

  • Examples of event alerts:
    • Database out of space
    • SQL Server was abnormally terminated
    • Database is corrupted
    • Table is corrupted
  • Examples of performance condition alerts:
    • Transaction log almost full
    • Number of merge conflicts exceeds an user-defined threshold
  • Examples of custom alerts:
    • Low inventory
    • Aborted download
sql agent
SQL Agent
  • Installed with SQL Server it is a task scheduler and alert manager.
  • Features:capability to email or page an operator when an event occurs
  • Provides history logs of scheduled jobs
  • Runs as a separate windows service SQLServerAgent
  • Make sure it is set to autostart

monitoring sql server
Monitoring SQL Server
  • SQL Profiler
  • System Monitor
  • SQL Server Enterprise Manager
  • Error Logs
  • Transact-SQL Statements
tempdb log full
tempdb log full!!

Error: The log file for database 'tempdb' is full.

  • If you have a development SQL Server life is easy, just re-start SQL Server. The tempdb is rebuilt on start up.
  • If a production server, then much more painful.
