Steps in loading your web contents - About browsers

Have you questioned yourself, why my browser is too slow ?????

To load the web page, your browser will traverse 11 sub systems or steps to display your web content :-) Interesting right !!! Let’s see,

1. Network – First subsystem which is responsible for client / server interaction. This relies on the hosted server’s performance and individual user’s network traffic.
2. HTML – Followed by the HTML – sub system. This allows you to download the HTML content from the server and structured it back to the client machine.
3. CSS – Cascade Style sheet, this will provide you the customised colouring and structure to the content. The details will be collected and it will be used later (In point 8).
4. Collections – Accessing metadata information related to your HTML. This guy will take care of Segregating your head and body contents separately.
5. Java script – Client side scripts which will execute based on the user’s action.
6. Marshalling – Java script engine can’t directly interact with the browser. Marshalling is a special communication layer between JavaScript engine and your browser.
7. DOM API – Special API’s responsible for interaction between JavaScript engine and your browser.
8. Formatting – All your objects will be formatted based on the CSS information collected.
9. Block building – Your objects will be segregated as separate blocks
10. Lay out formation – Now, depends on your Web parts or Frames or div tag or Table. Your layouts will be formed.
11. Image Rendering – Rendering of images (or) drawing to the screen through CPU or GPU.

SQL Profiler InputBuffer events in SQL Server

As a DBA, sometimes you need to identify the last execution happened or happening in your server. What you will exactly do?
1. Start your profiler and check it.
2. Check the process info for the server processes running.
3. In SQL Server 2008, you can opt Activity Monitor.

What else?????????

Here is another method using queries? If you got the spid then DBCC Inputbuffer command will provide you the last execution command of your user. Let's see how?????


Get the current session id

SELECT @@SPID
The output is, 51

Let's execute the below query now,

CREATE TABLE VENKAT_TABLE (Col1 int)
GO
DECLARE @i int;
SELECT @i = 0
BEGIN TRAN
SELECT @i = 0
WHILE (@i < i =" @i">


Now, open another session or connection, and execute the command

DBCC INPUTBUFFER (51);

You will get the last statement executed by the particular session user.

Usually, we will get confused on seeing the sequence of below statements in our profiler.

create table #tmpDBCCinputbuffer ([Event Type] nvarchar(512), [Parameters] int, [Event Info] nvarchar(512))
insert into #tmpDBCCinputbuffer exec ('DBCC INPUTBUFFER(51)')
select [Event Info] from #tmpDBCCinputbuffer

It's nothing but the in-house or profiler query itself. The above statements were used to fetch the latest statements of your server processes.

thanks in advance
pinky

----------------------------------------------------------------------------------

It's a very usual question. How to use "Like operator on a column" -> We should use inner join on TableA.Column_Name like TableB.Column_Name

Let's see a small example to understand a little bit.

DROP TABLE PINKY1
DROP TABLE PINKY2

GO
CREATE TABLE PINKY1(NOTES VARCHAR(100))
INSERT INTO PINKY1 VALUES('VENKAT')
INSERT INTO PINKY1 VALUES('VENKATESAN PRABU')
INSERT INTO PINKY1 VALUES('rENKAT')
INSERT INTO PINKY1 VALUES('AENKAT')
INSERT INTO PINKY1 VALUES('AENKAT')
INSERT INTO PINKY1 VALUES('zxNKAT')
INSERT INTO PINKY1 VALUES('zxNKAT')
INSERT INTO PINKY1 VALUES('zxNKAT')
INSERT INTO PINKY1 VALUES('VERESEAEz')

GO
CREATE TABLE PINKY2(VAL1 VARCHAR(100),VAL2 VARCHAR(100),VAL3 VARCHAR(100),VAL4 VARCHAR(100),VAL5 VARCHAR(100))
INSERT INTO PINKY2 VALUES('VE%','%RE%','%SE%','%AE%','%E_')
INSERT INTO PINKY2 VALUES('BE%','%RE%','%SE%','%AE%','%E_')
INSERT INTO PINKY2 VALUES('SE%','%RE%','%SE%','%AE%','%E_')
INSERT INTO PINKY2 VALUES('DE%','%RE%','%SE%','%AE%','%E_')

GO

SELECT * FROM PINKY1 INNER JOIN PINKY2 ON NOTES LIKE VAL1
WHERE NOTES LIKE VAL2 AND NOTES LIKE VAL3 AND NOTES LIKE VAL4 AND NOTES LIKE VAL5

All about user creation in SQL Server

Creating a new user in SQL Server:


Goto SSMS -> New User. Provide your user name, in my case its sample_user

Choose the authentication and choose the default database.



Default database indicates the database to which the user is having the access. In the next page, you can specify the level of access to the user. The next drop down is Default language -> I have made it as default and it's English.

Arabic, Brazilian, British English, Bulgarian, Croatian, Czech, Danish are some of the languages listed.




In the next window, you can specify the role of the user and it's server role. I have informed that, this person is a sysadmin and public too.


Next option is "User Mapping", here all the database will be listed. You can specify the level of access to be provided to this user for each database.

I do not want to provide any other access to this user except "VenkatDB".

Next screen is securables, you will have list of objects like Server, Endpoints and Logins.

You can choose the object on which you want to provide or deny access.

For example, I have selected Server -> Select an option "Create any database" and -> Select deny option. Here, we have restricted the user to create any database. Still, he is a sysadmin but he can't create any database.

The final page is status. It will define the current state of the user.

Now, let's move to our actual topic.

How to prevent access to a database for a particular SQL Login user????

Consider am having a user who is having access to multiple databases? I want to restrict the user not to use "VenkatDB" - > A specific database.

Now, you need to first make the user as public.

Provide necessary access level in the database level. Make the user as public for that specific database. Now click "OK". Reopen the login page for that particular user. "VenkatDB" is disappeared.

Now, I am trying to access the objects in the database. Below is the message received.

" The server principal "venkat" is not able to access the database "VenkatDB" under the current security context. "

Check the Updates in our machine

This one is pretty interesting findings, I found the check box "Show Updates" in the Add or Remove Program.

On selecting the check box, you will see a fantastic difference in listing the installed softwares.
It's a tree nature display which will give the information like which one is the master one and what all the patches applied on it.

It's a fantastic feature and I found it today!!!!! Eurekhaaaaaaaaaaaaaaaa

Select Statements to access stored procedures

Is it possible to use the select statement to access stored procedures?????

In one of the difference between functions and stored procedures is, we can use the "select"
statement in functions whereas we can't use the same in stored procedures.

Can we make this statement false????? Not completely but a little bit.

Before that, am trying to create a Linked server.

Goto SSMS -> Your DB Server -> ServerObjects -> Linked Server - > Create new Linked Server.

You will get a message box to type your Linked server. You need to provide the servername.

Specify whether it's SQL Server or not. If it's not SQL Server, provide necessary details to connect it.

The second window is authentication, you need to specify the credentials used to access the Linked Server.

The third window specifies the options to be provided for the Linked server. If everything is good. Click "Ok" button.

Now, your Linked Server is created.

Now, you can see your catalogs listed under the Linked Server.

Now, am trying to access the Linked Server's table,
SELECT * FROM LinkedServer.VENKATDB.dbo.VENKAT_TABLE

Awesome,

Am able to see my data.

Goto your Linked Server query window and create a procedure (use the below code)

DROP TABLE VENKAT_TABLE_LINKED
CREATE TABLE VENKAT_TABLE_LINKED (ID INT)
INSERT INTO VENKAT_TABLE_LINKED VALUES (1)
INSERT INTO VENKAT_TABLE_LINKED VALUES (2)
INSERT INTO VENKAT_TABLE_LINKED VALUES (3)
INSERT INTO VENKAT_TABLE_LINKED VALUES (4)
GO
DROP PROCEDURE VENKAT_PROCEDURE
GO
CREATE PROCEDURE VENKAT_PROCEDURE
AS
BEGIN
SELECT * FROM VENKAT_TABLE_LINKED
END
GO
EXEC VENKAT_PROCEDURE
GO

Now, your procedure is created in the Linked server and am trying to access that procedure from the actual server using select statement. Le's see how to do it.

This can be achieved using OpenQuery statement.

SELECT * FROM OPENQUERY ([LinkedServerName],'MASTER.DBO.VENKAT_PROCEDURE')

So, the statement is wrong :-)

The actual statement is, "Stored procedures can't use Select statement in it's own server"

Hope, you all agree with my statement.

Linked servers in SQL Server

Linked Server -

It's quite a different area, which I would like to concentrate more. What's this???? linked server......

Accessing the resource in the other server can be achieved using Linked server. Considering am having a server named "ServerA" and I would like to grab some data from the remote server named "ServerB". In that case, we need to create a linked server. In our scenario, the linked server is "ServerB".

Let's see, How to link it? How to access the data?

Goto SSMS -> Your DB Server -> ServerObjects -> Linked Server - > Create new Linked Server.

You will get a message box to type your Linked server. You need to provide the servername.

Specify whether it's SQL Server or not. If it's not SQL Server, provide necessary details to connect it.

The second window is authentication, you need to specify the credentials used to access the Linked Server.

The third window specifies the options to be provided for the Linked server. If everything is good. Click "Ok" button.

Now, your Linked Server is created.

Now, you can see your catalogs listed under the Linked Server.

Now, am trying to access the Linked Server's table,
SELECT * FROM LinkedServer.VENKATDB.dbo.VENKAT_TABLE

Awesome,
Am able to see my data.

SQL Server installation issue with Windows XP sp3

I happened to install SQL Server in Windows XP sp3 version. Oops, I couldn't make it out.

1. Am facing issue with MSXML6.

2. Because of the above point, workstation components and Database services were not installed in my machine.

Reason for this issue:

MSXML6 is trying to change the language settings of WindowsXP sp3 which it couldn't succeed. So the installation is failing. Looks like, it's a well know bug.

Just checking for the workaround, I found the below blog which may be useful for you. Please check it out,

Format files in SQL Server

For many years, I used to think about writing an article on Format files. I got shocked on seeing a procedure which is using format file and I am not aware of this area. Anyway, Learning starts or goes only if we don't know something right!!!!

Come one........Let's learn something...........

BCP - Bulk copy program

1. It's a utility to copy the data in bulk.

2. Data from files (or) to files in a specific format can be achieved using this BCP.

Format file:

1. If we want to read a file, it's very hard for SQL Server to read the file and store it in the database. Yes, we can store it but it will varchar field in the database.

2. To inform SQL Server about the datatype in the files. We use the Format file.

3. The Format file will tell you that, the file holds integer value, datetime field value with length 10 etc..,

How to create a Format file????? Let's see the below example to understand it.

Am having a table named Venkat_table

Below is the command to get the Format file,

bcp Venkat_Table format nul -S servername -T -n -f C:\Venkat_TableFormat.fmt

The Syntax is like, BCP DatabaseName.Ownername.ObjectName format nul -S servername -T -n -f formatfilename

nul - If there is no data file name to load. Here, we are fetching data from the table.

-T - Indicates trusted authentication or else -U and -P should come (SQL Server authentication)

-n - Indicates native data type. We will discuss more below.

-f - Informing the format file

We should go to the Windows command prompt and execute the above command, a file will be generated in the desired location.

On opening the Format file, you will get the below details.

Here is a generic details to understand the format file.

bcp Venkat_Table format nul -S servername -T -c -f C:\Venkat_TableFormat.fmt

-C indicates the type of columns to be assumed. C indicates the char type. In the below pic, you can see the datatypes were located as character datatype. If it's -n, then the datatype is native datatype.
