Sql Server Development Series – DataBase Design Practice Day 6 of 60

Create a new User defined data base.

We can do these object creation using


2. Through t-SQL Script

We will go through the first SSMS option

Go to run and type SSMS and log in to sql server instance and

Right click on databases options, you will get like below

We got below window

Type Database Name, you will see the logical name also changed as per our given Name

But we can change the logical name, it’s not a problem

Click ok. It will create the database.

We can also do this database creation using the below command

create database testdataBase_script

If we go to properties of newly created Database, by right click on Database and select options

And you go to files option, you will have below window

You will have the files information for this Database

Logical name of the file is unique to the Database.

You can have the same file name in the other database


By default, if you did not specify the location, it will create the file in the sql server system databases locations


There is the difference in the size of the files that were created though the command and UI

Whenever we are creating the database, we will give the name of the file.

Location, initial size, maximum size, auto growth

Initial size:

What is the size of the file when it was created?

Maximum size: we can specify this in the below window using UI

You will get the below window

Auto growth: if the initial file size is full, then sql server will allocate the specified MB as per option setting.

We have below set below option

If initial log size is 4 MB, and it is full, then sql server will allocate 10 MB,

If that is also full (14MB) then it allocates another 10 MB.

If 94 MB is full, then it will allocate 6 MB, as the max size is 100 MB.

If 100 MB is full, then it will allocate the data to any other files in the same file group.

If no files are there in the same file group in which this file was exist, then sql server will not allow the User to perform the write operations and it is used only for read operations.

If we have done the update also, then sql server will not allow that operation as sql server needs the memory for internal fragmentation

Create a new database banking _system.

We can change the initial size of the file whenever creating the database.

As the new Database creation is done from Model DB template, go to model DB, then give initial size as below

We can create the different files for the database

If we need the new file groups, click like below

Give the file group name and Click OK.

Like that, add the new files for the Banking_System

In the path, we given the directory names, but that Directories should exists in the System.

Sql server will not create the directories.

Click on OK, we will have database created and files are on the directories like below

Limitations of creating Files and file groups through UI

We can have the primary file group files in different folders other than system databases defined folder

You can create the file group that have .MDF file also using the script

We cannot give the name for the primary file group as it is default one

Below statement will add the file to the default file group i.e. primary

We can add the file to file group like below

A filegroup can be there with no files also.

Later we can add the files

Create one database University using the below script

I did not mention the log file info, but we have the log file created for this database

Why it was created is due to model database

Please check and let us know if you have any concerns on this.

Sql Server Development Series – Installation and configuration of Sql Server Day 4 of 60

Hi folks,

Below is the installation of sql server 2005 and you need to go to servers folder, you have to follow the below instructions

We can click on the setup.exe for windows server and the splash.hta for Linux and MAC servers

Microsoft strictly told to use sql server in windows server for more security

Click on the set up and you will get the below screen

The above phase will install the pre requisite for sql server means .Net frame work

And it will be installed by this set up automatically, no need of .net framework manually.

This was applicable for non-express editions.

You can see the manifest files in the sql server installation folders

This will have the links for other files.

Click on next, it will Scan the your system configuration

Click on next, and you will be go to sql server installation window

Click on next, we can have below different components to choose.

SQL server is installed on windows server and sql have below components.

We can install 50 sql server instances w.r.t edition and version

Each and every successful installations are called instances

We can have 50 unique instances in the one OS

If we have default instance, the instance name is same as machine name

SSIS and Work station components can be shared among 50 instances.

Click on next, you will get below window

Based on the components we have selected for installation we can have the services that needs to be started at the end of installation

Sql browser component will always run on the network security account not on the local system account

Click on next, we can have the authentication types,

Windows authentication- only windows users can login

Sql server authentication- non windows user can login

If you have both type of users, select mixed mode else select windows authentication mode

Click on next, we have collation settings windows, using this we can give the case sensitivity and ascending /descending order

Sql server will have 31 languages support, it is default supporting Latin language

Click on next,

Click on install. It will install the sql server on your machine.

For 2008 installation, Please watch the below video

Sql Server Development Series – Sql server configuration manager Day 3 of 60

Hi Folks,

Below is the discussion on the Sql server configuration manager

Mainly it is used for playing with the services.

1. Starting and stopping of service

2. Password change

3. Configure the startup mode of services

4. Enabling the database with single user mode or multi user mode

This is the sql server tool for playing with the sql server services

Another way to go to run -> services. MSC

We have sql server services in this

Don’t start sql server services all if we don’t have requirement as each service will consume minimum of 50mb and max of 8GB

Apart from the services, we have network configuration in the Sql server configuration manager(SCM)

Network configuration in SCM is like below



We are mainly using the TCP/IP protocol mostly called transmission control protocol /internet protocol

Coming to the protocols, this are used for data communication between client and server and this data is of encrypted TDS packets

We have already discussed this in the below post

if you have trusted internet connection you can connect to the sql server using the TCP/IP protocol

client and server will talk to each other using TDS packets and TCP/IP protocol is used for converting the data in to encrypted packets

Named Pipes:

if we are using the client and server in the same machine, we can use the named Pipes

it is also applicable for machines across the LAN

Shared memory:

clients and server can use the common memory and these are in single machine

before sql server 2005, we have option to install client components or server components

VIA-virtual access

mainly for internet and it is very faster, but not much secure than TCP/IP protocall

we can define protocols independently for each instance of sql server

by default

shared memory and TCP/IP protocol is enabled and others are in disabled mode and we can change it as part of requirement

how the sql server will check these protocols in the order


We have the client protocols in the sql native client configuration and it is defined with order

First shared memory is with 1st order, so sql server will check the shared memory and if the client is not in same machine, then sql server will skip this and check the TCP/IP and if TCP/IP is not working then sql server will go to named pipes

We can change the order of these protocols in configuration manager


An alias is an alternate name that can be used to make a connection. The alias encapsulates the required elements of a connection string, and exposes them with a name chosen by the user. To create an alias for the Microsoft SQL Server clients on this computer, right-click Aliases in the console pane, and then click New Alias. To configure an existing alias for the SQL Server clients on this computer, click Aliases in the console pane, right-click the desired existing alias in the details pane, and then click Properties.

Configuring client aliases for SQL Server

1. Open SQL Server Configuration Manager, and expand the SQL Native Client Configuration node.

2. Right-click Aliases, and then click New Alias.

3. In the Alias Name box, type the alias you wish to use when connecting to the database server.

4. In the Port No field, type the port number that you assigned to your SQL Server instance.

5. In the Server field, type the name of your database server.

6. Click Apply, and then click OK.


Start, Run, clicnfg

Enable TCP/IP protocol


Select properties


Select Alias Tab

Sql Server Development Series – SQl Server Architecture Day 2 of 60

Sql Server is perfect RDMS product from Microsoft used to perform day to day operations and management activities

How sql server manages Client server communication:

MSN uses sql server as backend

Below is the picture of sql server architecture


Whenever you are login into the msn account using the credentials these credentials are passed from the client API to server API (sql server)and validation is done

If we are sending directly the credentials from the client API to server API , security issues will raise.

So we are using the encryption here

At the client API, the credentials are encrypted so that only target server can only understand. For this we are sending the data in the TDS (tabular data stream) format to the protocols

API (application programming interface): in order to interact with database or s/w to pull or push the data ( Ex:HTML )

For the encryption at sql server, we are using the protocols and these protocols are also called network libraries (net Libs)

TCP/IP, named pipes, shared memory, VIA

TCP/IP is mostly and widely used protocol

After data is encrypted using the protocols and this data is routed to specific destination server using the drivers (OLEDB,ODBC)

OLEDB- specific for Microsoft technologies like IE->sql server,.net to sql server, SharePoint to sql server, sql server to sql server

ODBC is used for data communication of sql server with non-MS technologies.

Driver should not know what the data it contains and how the data is encrypted and its job is to route the data

And these encrypted information (packets) are called TDS packets and why we are converting these into tabular formats is RDBS only understands tabular formats

After the data is converted Tabular format, we are applying security mechanisms and send to server


Client is sending the data to the server using the LCM (least cost method)

At the server we are taking the data using drivers and gave to netlibs(protocol’s) and they will convert the encrypted data to decrypted one using the same protocol the client is using for the encryption. Otherwise the connection failures will occur even though the server is up and running fine

Here client net lib and server net lib should be same

After the data is converted into decrypted format(TDS packets) then this data is given the server and server executed and gives the response to the client

There are 2 types of connections:

Server centric connection: syntax check will occur at server

Client centric: syntax check will occur at client

Now – a –days, we are using client centric connections so that traffic to the server will be reduced and performance will be increased

Please check and let us know if you have any concerns on this.

Sql Server Development Series – Introduction to Sql Server Day 1 of 60

It is mainly for DBA’s and useful for developers and support folks and it covers exam (70-431)

From sql server 2005, Microsoft changed lot in sql server product

Before there is no integration of developers and DBA‘s and now MS introduced integration of Developers and DBA’s

3 types of roles in sql server

1. DBA

2. Developers

3. Users

Roles of DBA:

Managing, monitoring and changing the health performance, reliability, security of the system

Developer will develop the objects in sql server

Users will use the results from the sql server

Roles and responsibilities are same for the developers and DBA’s but in 2000 DBA‘s uses enterprise manager for admin tasks and developers used query analyzer

Now in 2005, these are gone and they are integrated into sql server management studio

Sql server 2005 breaking all the records of bench mark testing and there is 7% increase in performance

Over oracle 10g and 37% lower cost so many people will get the product at low cost

We can install different instances of sql server on one server

In one machine, we can have the sql server 2000 instance, sql server express instance, sql server 2005 test instance like that

SQL Server from beginning:


Sybase company created the Sybase sql server for Unix ,at the time oracle is the having the biggest database in the Microsoft decided to partner with Sybase

1993 – 4.2.1 version:-

They developed the Sybase sql server i.e. integrated with Windows NT 3.1 operating system

Most of code is for Sybase developed and this Sybase sql server is coded for Unix also called Sybase sql 4.0


MS and Sybase divided and MS developed the own sql server of version 6.0 for Windows NT 3.1 and 3.5

But the code is Sybase code and Microsoft decided to use their own code. Introduced the replication concept


MS released 6.5 version with better features with integration with windows NT 4.o and it is poor in performance, but lots of new features

1999-7.0 version:-

Microsoft did the new code (all MS code)

New GUI, OLAP, Data ware houses,scalable,fast,reliable

Sql server 2000: 8.0 Version:- with many enhancements like analysis services

SQL Server 2005: 9.0 version:-Code Name (Yukon)

Reporting services, service broker, SSMS. Here everything is touched.

SQL Server 2008: 10.0 Version:-Code Name (Katmai)

File Stream Data, Data Compression, Log Stream Compression, Language-Integrated Query, Spatial data, User-Defined Table Type, hierarchy ID, New Collations, Sparse Columns

SQL Server 2008 R2: 10.5 Version:-Code Name (Kilimanjaro )

SQL Server 2008 R2 includes a number of new services, including Power Pivot for Excel and SharePoint, Master Data Services,

Stream Insight, Report Builder 3.0, and Reporting Services Add-in for SharePoint, Master Data services, hierarchies, Multi Server Management

SQL Server 2012: 11.0 Version:-Code Name (Denali)

File Table, Statistical Semantic Search, Improved Full text Search, new and enhanced spatial data types, Paging, new Throw Statement, Sequence Object, and new Functions for development.

Sql Server tools and components:

Management tools:

1. Sql server management studio

Here the sql server enterprise manager and sql server query analyser in sql server 2000 are integrated and developed this tool.

2. Sql server configuration manager

It will replace the client network utility, server network utility and service manager in the sql server 2000

And these three tools are integrated and replaced by the sql server configuration manager like below from sql server 2005 onwards

I explained about this tool in my blog

Development tools:

1. SSMS (sql server management studio) for writing the queries and creating the objects in sql Server.

2. Business intelligence development studio: for developing SSIS, SSRS,SSAS applications Called as BIDS

Performance tools:

1. Database engine tuning advisor:

The Database Engine Tuning Advisor enables you to tune databases for improved query processing. Database Engine Tuning Advisor examines how queries are processed in the databases you specify and then it recommends how you can improve query processing performance by modifying physical design structures such as indexes, indexed views, and partitioning.

It replaces the Index Tuning Wizard from Microsoft SQL Server 2000, and offers many new features. For example, Database Engine Tuning Advisor provides two user interfaces: a graphical user interface (GUI) and the dta command prompt utility. The GUI makes it easy to quickly view the results of tuning sessions, and the dta utility makes it easy to incorporate Database Engine Tuning Advisor functionality into scripts for automated tuning. In addition, Database Engine Tuning Advisor can take XML input, which offers more control over the tuning process.

2. Sql Server Profiler :

Microsoft SQL Server Profiler is a graphical user interface to SQL Trace for monitoring an instance of the Database Engine or Analysis Services. You can capture and save data about each event to a file or table to analyze later. For example, you can monitor a production environment to see which stored procedures are affecting performance by executing too slowly etc.

Sqlcmd is the sql version of command line tools: it replaces the Osql. Osql is completely gone

Before Sql DMO (data management objects) is the object library for sql server and now it is replaced with SMO (sql management objects) .

Components of Sql server:

1. Database engine: it is not changed for execution

2. SSAS (SQL server analysis services): we can develop multi-dimensional objects such as cubes etc.

3. SSIS (sql server integration services): for developing ETL packages

4. SSRS (sql server reporting services): for developing the reports

5. SSNS (sql server notification services): send the notifications to anybody on any device

And it is removed in sql server 2008

6. SQL server service broker: it like the message queuing system which keeps the messages and other application will pick those messages and process

In configuration tools, we have tools like

1. Sql server configuration manager:

I already posted one post on this

2. Notification services command prompt

For managing notification services. It is removed in sql server 2008

3. Reporting services configuration: we can configure the reporting services instances here

If you open this tool, you will get like below

We can connect to the report server instance and manage the properties

4. Sql server error and usage reporting:

We can send the errors to the Microsoft that are occurred in sql server by using this tool

Sql server surface area configuration Manager:

It will do all the checks and Surface area reduction is a security measure that involves stopping or disabling unused components

It is removed in sql server 2008

We can have the documentation and tutorials: and it has mobile edition tutorial and sql server tutorial and sql server tutorials and sql server books online for learning



We can register the server s here in the SSMS so that we will query and manage them whenever you want

In sql server 2000, we have register servers like this

We can query and manage these servers.

Here Green mark represent the server is connected

In SSMS(from Sql server 2005) for registration of servers, go to view and registered servers you got window like below

By clicking and register the server

Save it and you can see the registered servers like below

Here Green symbol means the server is up and running fine, but we are not connected to the server

So to connect right click on registered server and new query so that it is connect to server and shown in the right window

If we go to any database and see the reports of database, follow like below

These are reports, and we have bunch of reports and gives the all details about the database

Solution explorer: it is used to for maintaining the projects

For creating the projects, file-> new-> projects-> select the project type and —- and click ok. You will get the project in the solution explorer in the right side and it is like below

Running the queries in ssms is very easy, go to database and right click and select new query

And you can create the queries and execute the queries

Please check and let us know if you have any concerns on this.
