Find all the dates in a date range ? TIP #100

 

It’s almost one month that I didn’t write anything on the blog due to some personal reason. I am really sorry for that.

Now , Lets talk about the scenario sometimes we need to generate a report of total sales in particular date range but the condition is you need to show all the dates whether there was any sales or not.

So first and most important thing for us is to determine all the dates between that particular date range and then determine total sales date wise.

To determine the all the dates which reside between from date & to date  we have 2 approches

First the classic approach with while loop  as shown below

DECLARE @StartDate AS DATE = '2005-07-01'
DECLARE @EndDate   AS DATE = '2005-07-29'
DECLARE @tblDateRange AS TABLE (salesDate DATE)
DECLARE @SeedDate AS DATE
SET @SeedDate = '2005-07-01'
WHILE @SeedDate <= @EndDate
BEGIN
  INSERT INTO @tblDateRange(salesDate) Values (@SeedDate)
  SET @SeedDate  = DATEADD(d,1,@seedDate)
END
SELECT * FROM @tblDateRange

Now second and interesting approach

DECLARE @StartDate AS DATE = '2005-07-01'
DECLARE @EndDate   AS DATE = '2005-07-29'
DECLARE @tblDateRange AS TABLE (salesDate DATE)

;WITH DatesCTE
AS (
SELECT @StartDate AS SalesDate
UNION ALL
SELECT DATEADD(d,1, SalesDate) As salesDate
FROM DatesCTE
WHERE DATEADD(d,1,SalesDate) <= @EndDate)

INSERT INTO @tblDateRange(salesDate)
SELECT * FROM DatesCTE

SELECT * FROM @tblDateRange

These are the 2 simple approaches which I like. I appreciate if you share other approaches which are simple & interesting.

How to hide my SQL Server instance in network ? TIP #99

 

In TIP #70  we saw how to find all the running SQL SERVER instance in a network or a machine.

to revise see below image.

This tip is just opposite to tip #70 you don’t want that your co-worker see your SQL Server instance running on your machine machine. (There are several reason behind this   and security is one of the most valuable aspects)

To achieve this you just need to do a very simple setting. Just follow below steps

1) Open “SQL SERVER Configuration Manager”

2) Once the screen is open right click on the instance which you want to hide from network (under  SQL SERVER network  configuration ) as shown below

3) When you click on Properties menu you will get a new screen as shown below

You need to set the value of Hide Instance option to Yes.

4) Click on apply button and restart the services.

Great , We achieved it. Isn’t it simple ?

I appreciate your feedback.

I am not able to access my SQL server instance on another computer tip #98

 

On last Friday , one of my colleagues had some issue related to accessing of SQL Server instance of database server machine in the office through his machine. I think this is generalized problem and might be faced by many of us.

So to begin with  default port of SQL SERVER is 1433 , I am sure most of us aware of this.

If we are facing such issue then most of the time it means port 1433 is not opened on SQL SERVER instance machine.

To open the port 1433  we have to follow below steps 

1) Open firewall (using Firewall.cpl command ) as shown in below figure

2) You will get below screen now click on Advance setting option as shown in below screen

3) You will get a new screen. In this we need to add a new rule for for “Inbound” & “outbound” by clicking the respective navigation menu. When you will click on “Inbound rule or outbound rule you will below screen. Now click New Rule link as highlighted below

4) When you click the New rule link you will get a new screen. Now in this screen select port radio button and click on next button 

5)Now add specific local port 1433 as shown in below figure 

When you click next button you need to choose option “Allow the connection” and you are good to go by click Next button

 

These same steps you have to follow for Inbound & outbound rules and your SQL port 1433 will be open and you will be able to access your sql server instance from other computer machine.

I hope this tips might resolve your problem too.

Enjoy!!!!

How to send E-mail/E-mail with Attachments in SQL Server TIP #97

 

In last post, TIP#96 We have configured Database E-mail. Now in this post we will see how to send mail in SQL SERVER.

Sometimes we need to send mail for different requirements like

1) Notification mails like  data inserted /updated/deleted successfully

2)Send data reports like no of amount earned, failed transaction  etc.

for this SQL SERVER provides us stored procedure “sp_send_dbMail”.

The “SP_send_dbmail” has various parameters below are some important parameters like

@profile_Name : The profile which will use to send mail

@Recipients : To whom the mails need to be send

@body : This is message body

@Subject: Subject of the mail

@Query : SQL statement which you want to share

To send a simple E-mail  we can write following statements

EXEC msdb.dbo.sp_send_dbmail
    @profile_name = 'IndiandotnetMailSmtp',
    @recipients = 'rajatjai@gmail.com',
    @body = 'Mail sent successfully.',
    @subject = 'Mail via SQL SERVER ' ;

We can also send a query result either inline text format or html format or as a  attachment

Below query will send mail to me with count of students of a class. the below mail is simple text format mail

EXEC msdb.dbo.sp_send_dbmail
    @profile_name = 'IndiandotnetMailSmtp',
    @recipients = 'rajatjai@gmail.com',
    @query = 'SELECT COUNT(1), Class FROM IndiandotnetDB.dbo.tblStudent GROUP BY class' ,
    @subject = 'Mail via SQL SERVER ' ;

The above mail can also be send mail as a attachment with following command

EXEC msdb.dbo.sp_send_dbmail
    @profile_name = 'IndiandotnetMailSmtp',
    @recipients = 'rajatjai@gmail.com',
    @query = 'SELECT COUNT(1), Class FROM IndiandotnetDB.dbo.tblStudent GROUP BY class' ,
    @subject = 'Mail via SQL SERVER ' ,
    @attach_query_result_as_file = 1 ;

We can add @body_format = 'HTML' and use various HTML tag in query or body parameters

A part from this you can cross check E-mail status whether mail is sent or not if it is not sent the what is the reason.

Below are the statements which can help to cross check mail sent status

-- Show all the emails

SELECT * FROM msdb.dbo.sysmail_allitems

-- Show all the  sent mails
SELECT * FROM msdb.dbo.sysmail_sentitems

-- show all the un sent mails
SELECT * FROM msdb.dbo.sysmail_unsentitems

-- show all the failed mail with reason
SELECT * FROM msdb.dbo.sysmail_faileditems

I hope this might help you somewhere.

Enjoy!!

Good things should be appreciated–SQL sentry Plan Explorer TIP #95

Although , It is out of box but I would like to share here. I am very choosy in food. When my mother/wife cooked food and I didn’t like the taste then I explicitly said I didn't like but when food taste was awesome then I didn't say a word.
My mother taught me “You should appreciate every thing which is good.” You’re single appreciation word do things
1. You feel yourself better
2. The person who did the good thing will be motivated to do more good things (in my case more tasty food wow )
This lesson of my mother is now one of the rule life.
So here I would like to say  one of the best tool I came across is “SQL Sentry plan Explorer”.   There are various great features of this tool but I would like to share few things which attract me more
1) It comes in two versions (Basic & professional ) .Basic version is absolutely free free free.
2) It makes SQL developer’s life easy. You can easily  cross check query plan easily.
see below snap.

You can also view logical read ,table scan and various other useful data

Very useful SET XACT_ABORT TIP#94

SET XACT_ABORT is one of the hidden gem we can say. It is helpful in many ways.
Let me explain by an example suppose you are working on a stored procedure which is doing a complex data manipulation. You though this query will run with in 1 minute when you run it from .NET or other code , but some how it took quite long time and with in one minute .NET or the code from which you run the query raised a command timeout.
Or we can say you have applied transaction in stored procedure and calling from .NET code and you have mention the command timeout in .NET .The ADO.NET program raised a timeout but still your query is running in background.
Now in such situation sometimes it happened the transaction which is running in SQL SERVER will be open transaction. Which might be  cause of locking problem.
In such situation  XACT_ABORT option is helpful.
By default XACT_ABORT option is off you can on it by following statement
   SET XACT_ABORT ON;
Now when this statement is on and if you face same situation as mentioned above it will rollback entire batch.
Let me explain with below example
Suppose I wrote following statement “Notice here XACT ABORT is OFF”

Now , when I run the above statements I will get following result in result window

And in the message window we will get following result

What it means instead of the error at least 3 records are inserted but sometimes you require either all or no record commit in the table then let me enable the option XACT_ABORT ON in the query

Now let me re run the statements again. When I run the above statements I got following result in message tab there is no result tab.what is means ??

It means what ever inserted is roll backed when an error occurred in a statement. Although The above example is not the best example of XACT_Abort but it will help to understand how to use it.

I appreciate your inputs on this valuable topic.
Thanks
