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!!

LESS but it is more–CSS Preprocessor with ASP.NET

 

Now a days a “ CSS  pre processor “ is a very famous buzz word.  Although I am a web developer but still I am not always interested in writing CSS  don’t know why.

When I heard about css pre processor then I was curious to know what it exact about.

So let me share my thought here about CSS Preprocessor.

So a  CSS pre processor is a way to extend the CSS language and variables, functions and programming  stuff.

As a developer you will be more happy to have pre processor because it allows you to write code and also reduce the amount of css up to some extent.

There are many CSS  pre processor are exists in the market  like LESS, SASS,

Stylus,clay and many more.

Now Let me share here how to use LESS.css in your ASP.NET code.

Step 1:-  Add  Nuget package Less.js

Less_Nuget_Package

once you added this package in your script folder you will get 2 new java script file with prefix less as shown below in figure

Less_Script

Step 2:- Now right click on content folder and add a new item which is LESS style sheet. This file will have extension .less

 

Less

Step 3:-  Now you can write your LESS related code as shown in below snap

lesscss

If you see above snap I declared  variable like @back-color , @font-color etc

and used in body.

Step 4: Now  add a web page and write following lines to enable LESS css.

<link href="Content/MyLessCss.less" rel="stylesheet/less" />
   <script src="Scripts/less-1.5.1.min.js"></script>

Test_Less_Page

step 5:- Now in web.config we need to add following mime type

Webconfig_less

Or you can add this from IIS.

Step 6: Now we are good to go and can run  it

sample_Less__page

So we get the color according to variable which we declared.

It means we can play with the variables and can write the less code in programming way.

I hope this post will give a step to go further and I am sure you will deep dive in CSS pre processor soon.

Enjoy !!!

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 a 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

image

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

image

And in the message window we will get following result

image

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

image

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 ??

image

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

RJ!!!
