When the status is "incomplete",then send a mail daily once to "so and so email id".

There are multiple ways that you can solve this. May I suggest writing a console-application that makes a SqlConnection to verify the status? It would be quite trivial to send an email from C#, and you can launch the application using Windows' task-scheduler.

That's probably not an i386-based device. Have you checked whether it is compiled against the correct architecture?

Here's a sweet alternative; you can download http://code.google.com/p/csharp-sqlite/[^] code, and include them directly in your project Smile | :)

Create the table first with the correct sizes, then import the text file into your table.

Table result to Xml

Hi,

I am trying to convert a table result to a xml. For example, I have a result (Figure 1) and I want to make an xml out of it (Figure 2).

I have tried the FOR XML RAW and FOR XML AUTO but this does not seem to give me the tree structure. Any ideas?

Figure 1:

Parent     Id     Name
-----------------------
0          1       Root
0          2       Root 2
1          3       Child 1
1          4       Child 2
3          5       Child 3
4          6       Child 4
9          7       Child 5

Figure 2:

<NodeCollection>
   <Node rId=1 Parent=0 Name='Root'>
      <Node rId=3 Parent=1 Name='Child 1'>
          <Node rId=5 Parent=3 Name='Child 3' />
      </Node>
      <Node rId=4 Parent=1 Name='Child 2'>
          <Node rId=6 Parent=4 Name='Child 4' />
      </Node>
   </Node>
   <Node rId=2 Parent=0 Name='Root 2' />
   <Node rId=7 Parent=9 Name='Child 5' />
</NodeCollection>

SQL query optimization

Hi All,

Thanks for those who take an interest in reading posts like these - and I sincerely hope that at least one of you can help me.

I am fairly new at SQL (without formal trianing...) so this might be very noob.

I have inherited the maintenance of a oldish software project. I am only getting to know the code and there is lot of it, so I feel a bit desperate. OK OK I'll get to the point!

My client needs me to solve a problem ASAP. They send out mail merge letters frm the application and they have a very sophisticated piece of code that allow you to filter the client database according to many criteria. When the criteria is entered it generates an integer (iParam below) that is used to filter a few tables. We use a autogenerated SQL statement for every report to populate it. The SP looks like this:

@iParam varchar(100)  AS 
SELECT 
ipkClientsID AS [ID], 
tblClients.sClientName AS [Client: Client Name], 
(SELECT CONVERT(varchar(8000), sTextValue) FROM tblReportSummary WHERE       ifkID = tblClients.ipkClientsID AND       iParam = @iParam AND       sFieldName = 'Client: Postal Address Group (R)')  AS [Client: Postal Address Group (R)] FROM tblClients 

WHERE ipkClientsID IN (SELECT ifkSelectedItemsID from tblSelectedItems where sID = @iParam)

as you can see the select statement is quite simple BUT for some reason the performance has gradually deteriorated over time to the point where every report that runs, times out or crashes the application (?).

I am hoping that you can take one look at it and say: That won't work well - try THIS!, as it might be a simple way of improving the select statement.

Much obliged!!! for any help or comments.

regards
Hawk

You could try

SELECT c.ipkClientsID AS [ID], c.tblClients.sClientName AS [Client: Client Name], 
	CONVERT(varchar(8000), sTextValue) AS [Client: Postal Address Group (R)] 
FROM tblClients c
Left join tblReportSummary r on r.ifkID = c.ipkClientsID 
	AND       r.iParam = @iParam 
	AND       r.sFieldName = 'Client: Postal Address Group (R)'
WHERE c.ipkClientsID IN 
(
	SELECT ifkSelectedItemsID 
	from tblSelectedItems where sID = @iParam
)

But I think you can best look at the Indexes on the tables.

Thanks Wout,

I will try your advice.

The indexes was the first thing I checked. There are indexes on both tables for all related fields - I was hoping for a quick fix there, alas my predecessor had already tried that.

I have now run through the code and it is definitely this stored proc that causes the problem. I am going to replace it with your statement and see what happens.

30 mins or so later...

Hi Wout,

OK your revised query worked (apart from minor error in line 1).

BUT - and this is interesting - I thought I had this one licked.

However I just ran Wout's suggested statement natively in SQL Manager and it produced results very quick. I tried a different parameter (different report) and it also worked well.

I then tried to run it from code - which actually calls a SP that contains the query as Wout suggested... and ALAS it takes forever...

I tried the original statement in SQL (not from SP) and it works very quick as well.

I then called the SP from SQL manager using "EXEC sp_...." and it also took forever.

It would appear that calling this transaction from a SP dramatically slows it down.

Why is this?

Any other good suggestions?

If the table tblSelectedItems is quite large, you would be better off linking it with an inner join, like this:

replace this bit:

Member 4648370 wrote:
WHERE ipkClientsID IN (SELECT ifkSelectedItemsID from tblSelectedItems where sID = @iParam)

With this:

inner join tblSelectedItems on ((c.ipkClientsID = ifkSelectedItemsID) and (sID = @iParam))

"Syscomments" system table corrupted

Hi,

I have SQL 2000 installed on my development machine. Things were fine till yesterday, but then things started turning out nasty.

I created an SP with name sp_retrieve_ageinginward_details ( I am aware that naming SPs with "sp_" as a prefix is not good ). Today just to make a minor change i scripted the SP, but it returns an error:

---------------------------
SQL Query Analyzer
---------------------------
[SQL-DMO]Object 'dbo.sp_retrieve_ageinginward_details' was not scripted. It is possible that the information in system table 'syscomments' about the object was corrupt or missing.
---------------------------
OK   
---------------------------

Also when i check the script from syscomments it gives me an error in an C++ file.

Server: Msg 3624, Level 20, State 1, Line 1
 
Location:	 recbase.cpp:1371
Expression:	 m_nVars > 0
SPID:		 57
Process ID:	 556

Connection Broken

How can i retrieve my SP from my DB Sigh | :sigh:

, since its huge and i have no backup. Cry | :((

Pls help.......

When you fail to plan, you are planning to fail.

If you can see it in object explorer try right click and that will give you an option to script it. Other than that, you may be able to pull the info out of syscomments by direct sql (id joins to id from sysobjects)

If this fails, then you have learnt the lesson - always save your sql to a flat file and put in in a vserion control system.

I have a C# program that has a connection to 2 different databases across 2 different SQL servers.

How can I easily copy a table and all its contents from one database to another using SQL statements in C#

I do not want to use the management studio to perform this and want to do it in my C# program.

Any help would be appreciated.

Solution 1:

Take the help of

SSIS

for the task. It is handy and simple.

Solution 2:

Using

SMO class

, you can create a backup of your database and restore it also.

There are plenty of articles in the net explaining how to do the same using SMO.

Please have a look

INSTEAD OF trigger

Member 4704143

8-Dec-09 13:34

Hi all,

I want to create a trigger relating to table Demo and table UpdateInfo. UpdateInfo is created as following:

CREATE TABLE UpdateInfo
(ID				int			primary key,
new				int,
click			int)

The task for this trigger is whenever there is a row inserted to Demo, there is an update in field [new] of UpdateInfo ( new = new +1) , but it wll just work, for example, from 1:00 am to 6:00 am.

If this has been done, I then want to customize the time from an aspx page.

I think I should start with INSTEAD OF trigger but I am lacking in experiences about it.

Could you give me any suggestion?

Thank you so much!
