Hello all.
In SQL Server 2012, it is possible to have an email sent to a group when a row is deleted from a given table?
Regards.
|

Not having tried this, but I would imagine you can create a trigger on delete from the table that calls a stored procedure to send an e-mail.
As for the syntax, you should be able to find how to create the trigger relatively easily.
But, for sending e-mail, that may be dependent on your e-mail platform.
|

|
|

I would not recommend sending an email directly from a delete trigger because you may pay a performance penalty and possibly abort your delete transaction if the email server cannot send your message.
Slight change in approach would be to write a custom "logging" table where you capture the entire row from the table and store it. You can then have a separate program read through this table and send emails notifying your distribution list.
The other advantage is that you have a copy of the deleted data. You can purge this data as you see fit.
Just and idea.

I'm converting some old CDao classes to ADO (ODBC) for Access database handling. Part of my code copies a table record from one database to another. When I do the CRecordset::Update I get a CDBException that completely unhelpfully tells me:
m_strError "String data, right truncated
m_strStateNativeOrigin "State:22001,Native:31,Origin:[Microsoft][ODBC Microsoft Access Driver]
Is there any way to get my code to tell me which field(s) is(are) causing the problem?

I would check the length of everything, data, parameter, target field in the table.

I tried that...I can't find it! 
Surely the driver must 'know' where this happens - why can't it just tell me?

It is the same with SQL Server and has always been an irritant. With SQL Server you have sql profiler and you can trap the actual statement passed to the database including data. You can then manually execute the command in management studio. This gives you a more detailed error response and you can use the mark I eyeball to inspect the data.
I know you can execute sql strings in Access but I do not know where to trap the command passed to the database from the client.
I would strongly suggest moving the database from Access to SQL server if possible.

That's impractical unfortunately.
I've checked all the text field member lengths before and after the Update, they both match each other and the database definition. The are no problems in DoFieldExchange. I don't know what to do next...
|
|
|
|
|
Hah! 
My fault of course - I was checking the wrong database definition - I had a field the wrong length!
oops!

Yah, done that well... yesterday actually!

Does anyone know how I can fix this in my following statement please?

From sqlservercentral.
Create a UDF and put this in it:
WHILE PATINDEX('%[^0-9]%',@string) <> 0
SET @string = STUFF(@string,PATINDEX('%[^0-9]%',@string),1,'')
SELECT @string

You are going to get better value out of an article than a forum post, there is even one from CP in these results[^]

That is not how the site works, we help you to learn how to create the functions, there are other sites that will do the job for you.

What is your question?
There are only 10 types of people in the world, those who understand binary and those who don't.
|
|
|
|
|
summing up marks per student(admno) based on the conditions given
|
|
|
|
|
Use a select query with a where clause on the subject group to get the group 1 students limit the output to 3 records (TSQL has a TOP function, not sure about MySQL)
For the second use the same query and change the where clause and the record limit. Add an order by on Marks to get the 2 records you need.
This is a microsoft answer, technically correct but does not meet you requirements which I suspect should have included - give me the codz!

thanks for the answer....but that works well for a single student but for many students it add all marks of all students

Ah my bad, I missed the add. You may need a nested select. First build your query to get the records you need and then wrap that in an aggregate query
select GroupID, sum(marks)
from(select GroupID, marks
From Table
Where Group = 'some code') X
group by GroupID
The query X gets the records you need and the outer query aggregates those records.
