Overview What is SQL Server? Creating databases Administration Security Backup

What is SQL Server? Database management software  Own file structure  Own logins  Own security Access through 2 main ways:  Query Analyzer  Enterprise Manager

What is SQL Server? Consists of 3 Services:  MSSQLServer Data & query processing  SQL Server Agent Scheduled jobs & alerts  Microsoft Distributed Transaction Coordinator Handles data from multiple sources

Logging In Windows NT Authentication SQL Server Authentication

Query Analyzer Command-based interface  Complete access to SQL Server  Useful for creating scripts

Enterprise Manager Graphical User Interface  Often more intuitive  Easier to visualize

Viewing Available Databases Query Analyzer  Execute sp_helpdb system stored procedure

Viewing Available Databases Enterprise Manager  Expand Databases folder

Creating a Database Enterprise Manager  Right-click Database folder  Select New Database…

Demonstration Creating medical database Set growth and file size options

Transaction Log Records data modifications Rolls forward completed transactions Rolls back incomplete transactions

Data Types At least 25 data types  char, int, float  uniqueidentifier, datetime, image Can define own data types

User-Defined Data Types Based on existing data types Created with sp_addtype system stored procedure

Creating Tables Query Analyzer

Creating Tables Enterprise Manager  Right-click Tables  Click New Table…

Creating Tables Enterprise Manager (cont.)  Choose name

Creating Tables Enterprise Manager (cont.)  Create columns

Demonstration Creating tables for medical database  Product  Patient  Usage

Constraints Maintain data integrity  Domain Integrity  Entity Integrity  Referential Integrity

Constraints (cont.) Primary Key  Entity Integrity Foreign Key  Referential Integrity CHECK Constraint  Domain Integrity

Add Primary Key Query Analyzer

Add Primary Key Enterprise Manager  Right-click column of interest  Set Primary Key

Add Foreign Keys Query Analyzer

Add CHECK Query Analyzer

View Constraints Query Analyzer  Execute sp_helpconstraint system stored procedure

Rules Specify allowed values for columns Example  Allowed states: PA, WV, OH

Creating Rules Query Analyzer  Create rule with CREATE RULE statement  Bind rule with sp_bindrule system stored procedure  Unbind with sp_unbindrule

Create Rules Enterprise Manager  Input only rule name and definition

Create Rules Enterprise Manager (cont.)  Bind rule Open rule properties

Creating Rules Enterprise Manager (cont.)  Bind Rule (cont.) Click Bind Columns… on Rule Properties Select table and column

Inserting Data Query Analyzer  Use INSERT statement

Inserting Data Enterprise Manager  Right-click table name  Select Open Table ► Return all rows

Inserting Data Enterprise Manager (cont.)  Type values as needed

Stored Procedures Collection of SQL statements Can accept variables Can be used for security  Users can be granted right to use stored procedure, even if they do not have access to underlying tables

Creating Stored Procedures Query Analyzer  Use CREATE PROCEDURE statement  Define variables

Using Stored Procedures Use EXEC procedure_name Pass values by reference or position

Transactions Process statements as a group Must be committed  “All-or-nothing” – All statements are committed or none are If interrupted, transaction is rolled back automatically

Transactions Query Analyzer  Use BEGIN TRANSACTION and COMMIT TRANSACTION statements  Use ROLLBACK TRANSACTION to cancel

Transaction Example Committed transaction Rolled back transaction Interrupted transaction

Views Specify how data is seen Focus data Security  Grant permissions on Views

Creating Views Query Analyzer  Use CREATE VIEW statement

Creating Views Enterprise Manager  Add tables

Views Enterprise Manager (cont.)  Select column names  Enter Aliases

Security User Management  Roles  Logins  Users Program Security

Roles Operations that members of role can perform Users are assigned roles

Creating Roles Type Role name Select Standard Role

Creating Roles Open Role properties Click Permissions button

Creating Roles Set allowed actions  Table actions  Allowed Views  Allowed Stored Procedures

Logins Allow users to log in to SQL Server Defined under Security folder

Creating Logins Input Login name Set password Set defaults

Creating Logins Choose allowed databases Select Roles

Users Who is allowed to access database Role user has

Setting Users Only necessary if you did not set during login creation

Program Security SQL Server Home Page  News, tips, & tools

Program Security Microsoft Baseline Security Analyzer (MBSA)  Runs under Windows 2000 or XP  Checks program settings & security patches  Useful for many Microsoft programs, including SQL Server 7.0 and 2000

Program Security MBSA can be downloaded at:  ?url=/technet/security/tools/Tools/mbsahome.asp ?url=/technet/security/tools/Tools/mbsahome.asp

Backup Create Backup Device  Container for your database Schedule Backup jobs

Creating a Backup Device Enterprise Manager  Look under Management folder

Creating a Backup Device Enterprise Manager (cont.)  Set name  Set location

Backing Up Back up and restore from Databases folder

Backing Up Select your backup device as the Destination Set a schedule if desired

Check Jobs Check backup jobs under SQL Server Agent under the Management folder
