ok,
I have solved my problem. I have changed the XML template. Now, the XML template is this:
<?xml version='1.0' ?>
<EmployeesList xmlns:sql='urn:schemas-microsoft-com:xml-sql'
sql:contenttype='html;charset=euc-kr' sql:xsl='EmployeesList.xsl'>
<sql:header>
<sql:param name='EmployeeID'></sql:param>
<sql:param name='Name'></sql:param>
<sql:param name='Title'></sql:param>
</sql:header>
<sql:query>
exec StoreProcedure @EmployeeID, @Name, @Title
</sql:query>
</EmployeesList>
As you can see, it executes a store procedure and pass it the 3 params.
Then, in the store procedure the params are checked and in function of their values a query is executed. Problem: I dont know much about SQL and it must be a query for each one of the possible combinations. I think this is very inefficient. The store procedure is this:
CREATE PROCEDURE StoreProcedure
@EmployeeID int, @Name nvarchar(30), @Title nvarchar(60)
AS
IF (@EmployeeID < 1 ) AND (@Name = '') AND (@Title = '')
BEGIN
SELECT EmployeeID, FirstName, LastName, Title
FROM Employees
ORDER BY EmployeeID
FOR XML AUTO
GOTO FIN
END
IF (@Name = '') AND (@Title = '')
BEGIN
SELECT EmployeeID, FirstName, LastName, Title
FROM Employees
WHERE EmployeeID = @EmployeeID
ORDER BY EmployeeID
FOR XML AUTO
GOTO FIN
END
IF (@EmployeeID < 1 ) AND (@Name = '')
BEGIN
SELECT EmployeeID, FirstName, LastName, Title
FROM Employees
WHERE Title = @Title
ORDER BY EmployeeID
FOR XML AUTO
GOTO FIN
END
IF (@EmployeeID < 1 ) AND (@Title = '')
BEGIN
SELECT EmployeeID, FirstName, LastName, Title
FROM Employees
WHERE FirstName=@Name
ORDER BY EmployeeID
FOR XML AUTO
GOTO FIN
END
IF (@EmployeeID < 1 )
BEGIN
SELECT EmployeeID, FirstName, LastName, Title
FROM Employees
WHERE FirstName=@Name
AND Title = @Title
ORDER BY EmployeeID
FOR XML AUTO
GOTO FIN
END
IF (@Name = '')
BEGIN
SELECT EmployeeID, FirstName, LastName, Title
FROM Employees
WHERE Title = @Title
AND EmployeeID = @EmployeeID
ORDER BY EmployeeID
FOR XML AUTO
GOTO FIN
END
IF (@Title = '')
BEGIN
SELECT EmployeeID, FirstName, LastName, Title
FROM Employees
WHERE FirstName = @Name
AND EmployeeID = @EmployeeID
ORDER BY EmployeeID
FOR XML AUTO
GOTO FIN
END
FIN:
GO
Is there another way to do this more efficiently?
Thank you very much! much!

It looks like your stored procedure can be simplified to one select statement:
<br />
SELECT <br />
EmployeeID, FirstName, LastName, Title<br />
FROM <br />
Employees<br />
WHERE <br />
(@EmployeeID < 1 or EmpolyeeID = @EmployeeID)<br />
and<br />
(@Name = '' or FirstName = @Name)<br />
and<br />
(@Title = '' or Title = @Title)<br />
ORDER BY <br />
EmployeeID<br />
FOR XML AUTO<br />

I am trying to import into SqlServerCe from an XML file. There is also a schema file available.
I have opened up the target .sdf database.
I used ReadXML to fill a DataSet from the xml file. Where do I go from here?

Does anybody know of free apps which can convert one database (Sybase Anywhere) to another (MSSQL)?
All that I seem to find are whitepapers (theory only, of course  ) from Microsoft and Sybase on how to migrate from one DBMS to another.

DTS? Don't know if it supports Sybase, but could be worth a look....

It worked. Sort of. Nothing but tables and data was copied. Triggers, indices and other bells and whistles were not copied.
I wish modern commercial databases had SQL dumping facilities (or at least mention them in the docs - I can't find them). Because I know I could probably hack up a perl script to convert most of the Sybase SQL into MS SQL. I know one can script tables and such in both Sybase Anywhere and MSSQL, but it doesn't script the data, just the definitions. I need both.

Hmmmm...have seen something similar before...
Seem to remember it being something to do with dependencies. The triggers and sprocs are dependent on the tables, but think that MSSQL tries to DTS them all at the same time, so if a table isn't present, then DTSing a trigger will fail.
You could try doing just tables, indices and data, then the other objects as a second run....
Good luck!

Pls I need anybody who can help with a data provider that I can use for accessing DB2 data on an AS400 machine using ADO.NET
I currently have one that works with ADO but when I use same connection sring with ADO.NET it throws an IUnknown error

Hi, I had the same problem, the solution I used is here.
You can also try IBM Client Access. (we have version 5 release 2)
"IBM DB2 UDB for iSeries OLE DB Provider"
With this I managed to set up the connection through vs ide (server explorer) and view the data.
Connection string I got from UDL file:
Provider=IBMDA400;Password="";Persist Security Info=True;User ID=ME;Data Source=xxx.xxx.xxx.xxx;Protection Level=None;Initial Catalog=AVISPAR2;Transport Product=Client Access;SSL=DEFAULT;Force Translate=65535;Default Collection="";Convert Date Time To Char=TRUE;Catalog Library List="";Cursor Sensitivity=3
Good luck!!

something like Profier of SQL Server, thanks!

No such luck!! Access (since it's essentially a single user desktop DB) generally has no need for such niceties.
You may however be able to turn on ODBC tracing....go to datsources dialog, specify a log file and click Start Tracing. Once you have the info you need MAKE SURE YOU STOP THE TRACE - this is V Important - tracing will cripple the performance of your machine, and is persistent across reboots....

thanks!yes, ODBC tracing can do for ODBC-Based App, but how can i monitor the app based on ADO or OLEDB?

Hello all,
When I close a web form that has a connection to my SQL Server, I am not seeing the memory process close in task manager (of the SQL Server). I am using the "open late close early" theory of database connections. I am using the "close" method for my database connections. Is there any automated utility that will shut down these processes? I thought when the user was disconnected from the database, the memory process would automatically shut down.
Any suggestions, thoughts, or ideas?
TYIA,

Suspect that what you are seeing is the SQLServer process itself...you really don't want this to be shutting down (do you?)...if it shuts down, then the server shuts down, and when you attempt to connect, it will fail.
When you CONNECT to a SQL Server DB, you just connect to a running instance of it, not (a la Access) run up a process etc.
Hope this helps, and apologies if have been barking up wrong tree!

Hi All, I am reporting with Crystal Reports for .net off of a live access database up on a web server. The database design sort of replicates a parts inventory and the way it was designed almost replicates recursion. For example there is a parts table and each row in the table has a part number, details, and a style number. The style number tells us whether it is a level 1 part, level 2 part, or a level 3 part. This database design supports an infinite number of nesting of parts within other parts using another table linked to the parts tables called packages with two links to the parts table. I am using ADO.Net datasets to report off of I am looking for a way to report on for instance all the level 1 or level 2 parts in a level 3 part or any combination like that. Has anyone ever created a crystal report that recursively looked up records in a database. Thanks in advance my head is going to explode soon I think

Hello all
I'm working on a data processing application which processes records in multiple (unrelated) tables containing about 2 million records.
Basically it runs through each record, checks various fields in each row according to certain business rules, and potentially updates other fields in the same row with updated values.
Here's my dilemma. I believe I have only 2 options available to me -
1. Using DataSet - I havent tried this yet but with 2 million records, it seems like its a very bad idea to try and pull a dataset of the whole table into memory while processing. Is there a way to page the dataset such that I can pull in only x number of rows into memory at a time?
2. Using DataReader - since I have to update the row after processing, using a data reader by itself won't work. I am currently using a datareader for iterating through the table and SqlCommands to update fields (though this seems to be prone to timeouts - I suspect that the writes to the database are locking out the datareader or vice versa)
Is there a better way to go about doing this sort of processing? Any suggestions would be greatly appreciated.

Do you relly have to load all two million rows at a time? Can't you restrict number of it with your query conditions? You can also use stored procedures to do you jobs in database side instead of application side.This have better performance.

Running through 2 million records on a SQL client kind of defeats the purpose of a SQL Server. I would let the SQL Server handle the task by one of these two methods:
1) Use a stored procedure that implements your business rules.
OR
2) Code an Update statement that implements your business rules.
|
|
|
|
|
I agree with Michael.
In this case, it is better if you use a Stored Procedure or an Update statement that has all the conditions (business rules) specified in it.

Thanks for the replies folks. But there's a good reason why I need to do this on the application side. The rules are fairly complex and involve a lot of calculations so implementing them in stored procs or sql statements is out of the question.
And I do need to process every record. Here's a couple of ways I am thinking of doing it:
1. Pull in x number records at a time based off a key field and process and update them before moving on to the next x number of records.
2. The other way is to use a datareader for running through the table and batch the SQL update commands somehow so that after X number of commands it executes them.
I've been told option #1 would likely be less efficient than #2 because of the overhead with creating and using DataSets and the fact that DataSets use Datareader internally anyway which would likely just be equivalent to option #2.
Any thoughts? Any better way to go about doing this?

I am using SQL server to handle my session variables. However every time I reboot the server the permission to call the SELECT queries get reset and I have to manual set them again.
To create the SQL Session server I used the script InstallSqlState.sql, should I have used InstallPersistSqlState.sql?
Thanks,

Well I figured it out, the answer is to write a procedure that goes off to set the permissions. Just have this code run by the SQL agent
use tempdb
Declare @userName char(100)
Declare @DatabaseUserID [smallint]
--internal sql user name or domain\username
Set @userName = 'InternalUser'
select @DatabaseUserID = [sysusers].[uid] from sysusers where name = @userName
IF @DatabaseUserID IS NULL
BEGIN
EXEC sp_grantdbaccess @userName
EXEC [sp_addrolemember]
@rolename = 'db_datareader',
@membername = @userName
EXEC [sp_addrolemember]
@rolename = 'db_datawriter',
@membername = @userName
END
