Thanks Colin Angus Mackay for reply
but it is not working
I even tried giving port no 1433 wit the ip address of machine but no success.
As there is no domain controller and all the systems are under same workgroup, if your solution works under these circumstances or not????

I don't think it's a connection string problem.
If the database is on server 2003 or XP SP 2, you needs to change some configuration values for it to work. You need to add sql server to the windows firewalls exceptions, open the ports, and change some registry settings.
It gets more complicated is you use the MSDTC but Microsoft provides step by step procedures. Search under SP 2 for SQL Server.

You need to use, ODP.Net , Data Provider for Oracle supplied by Oracle. Assuming you have that here is the example from Oracle

// Setup the Tables for sample

OracleConnection connection = new OracleConnection(connectStr);

I found a really cool function at http://www.devx.com/tips/Tip/20009.
You pass in in a string with what it's deliminated by and it returns a temp table variable of all of the data split into rows..
i.e
select * from fn_SplitByID('oranges|apples|pears|lemons','|')
1 Oranges
2 Apples
3 Pears
4 Lemons
All really nice and pretty. The trouble is I have a table products (around 2000 rows). Each has a product_code (varchar(255) primary key), stock level (int), with a description field that contains deliminated text 'blue|green|pink' (varchar(255)), etc.
I want to extract and split the data into a whole new table:
product_id product_code stock_level description
1 ABC NULL BLUE
2 ABC NULL GREEN
3 ABC NULL PINK
4 DEFG NULL SILVER
5 DEFG NULL GOLD
...
Yeah I am not worried about the stock_level, just need a null value into the new table, as the stock would have to be recounted.
I just keep getting stuck on how to do this. Maybe I've been looking at too many different ways and the answer is straight in front of me. If you have any suggestions I would be grateful.
Many thanks
Kev

hi all,
In our Application ,we have to use 175 SQL Functions.So there are many dependancies between each other.
That mean ,If we creating a function,we have to use several function to create it.
So I need to create a function relation ship between each other.(like relatinship between Tables)
Please kindly tell me,Is there a way to get dependancies and relation in functions?
thanks in advance.

You could use sp_depends[^]

hi everyone,
I want to update a row in a table in SQL with values from another row in the same table,
i wrote this:
UPDATE Income_Codes IC
SET IC.DateLeave = IC1.DateLeave
FROM Income_Codes IC1
WHERE IC.Cm = 420 AND IC1.Cm = 911
but it didn't work.
I tried this:
update Income_Codes
set DateLeave = (select DateLeave from Income_Codes where Cm = 911)
where Cm = 420
it worked, but if i have to update 20 fields, i have to write 20 selects, any other solution?
Thanks

delete the first row, and insert second row just changing the primary key

If you want both rows, then use the following
UPDATE table
SET (col1, col2, col3,..., col20) = (SELECT col1, col2, col3,..., col20
FROM table
WHERE <your_where_clause1>)
WHERE <your_where_clause_2>;

I tried it, but it gives an error,
any other solutions.
Thanks anyway.

Hi,
Anybody knows how to know if an ADO connection has been disconnected even before you execute anything? I have an application which has a global connection object and when it was disconnected from the server for whatever reason, it raises an error when you execute something even if the connection has been restored. Is there a way which I could know if the connection is still valid before I even execute anything? Thanks

You can check the connection state.

Hi,
Thanks for the response. I've tried that and it doesn't work. I also tried looking at the error count but it doesn't report any.

Oh, sorry about that. I take it the Connection State is showing the connection is still active?
alex1205 wrote: it raises an error when you execute something even if the connection has been restored.
In the original post you mention the next time you execute a query it throws an error. What is the error message it throws when this happens?

Hi all,
I have a question on sql writing
for a table schema as below
Table :
(studentID, studentName, courseID, classID, Age)
What is the correct sql of " select studentID from table where classID = "101" and group by courseID and order by age " ? (ie. Group by courseID, and within the same courseID, the studentID are ordered by age)
Thanks
|
|
|
|
|
SELECT studentID
FROM table
WHRERE classID = "101"
GROUP BY courseID
ORDER BY age
By default, ORDER BY will go in ascending order, if you want descending order use ORDER BY age DESC
Does this help?

SQL Server BOL [Books On-Line] (i.e. the built in online-help that comes with SQL server and it available on MSDN) have some excellent examples at the bottom of the pages on each of these T-SQL statements. All you have to do in C# is remember that you can run any T-SQL you like through the SqlCommand object.

We recently had a fire on campus. So we had to move all our data to new servers. The servers are supposed to be identical. I built a large DTS package to move some data into a database. I also made it a scheduled job, and a vb app that calls the scheduled job so our end users can run it by themselves. It was working fine in the previous servers. Now, if I run the DTS package, it works fine. If I try to run the Scheduled Job through Enterprise Manager or through the VB app it fails. Here is the error I get:
Executed as user: server\user. DTSRun: Loading... DTSRun: Executing... DTSRun OnStart: DTSStep_DTSExecuteSQLTask_1 DTSRun OnFinish: DTSStep_DTSExecuteSQLTask_1 DTSRun OnStart: DTSStep_DTSActiveScriptTask_1 DTSRun OnError: DTSStep_DTSActiveScriptTask_1, Error = -2147220482 (800403FE) Error string: ActiveX Scripting encountered a Run Time Error during the execution of the script. Error source: Microsoft Data Transformation Services (DTS) Package Help file: sqldts80.hlp Help context: 4500 Error Detail Records: Error: -2147220482 (800403FE); Provider Error: 0 (0) Error string: ActiveX Scripting encountered a Run Time Error during the execution of the script. Error source: Microsoft Data Transformation Services (DTS) Package Help file: sqldts80.hlp Help context: 4500 DTSRun OnFinish: DTSStep_DTSActiveScriptTask_1 DTSRun: Package execution complete. Process Exit Code 1. The step failed.
I am not sure why it will work if the DTS package is started by me, but not through the scheduled job. I have been working on this for days and I really don't know what else to try, any help would be GREATLY appreciated.

I have a DTS package, it works fine if I execute it in Enterprise manager. I set up a scheduled job for it, but if I try to start that job it fails. So it works if I run the DTS package, but not if I try to run the job that calls the package. I read the error message and it says it is trying to execute the DTS package as a local user instead of a domain user. In the DTS I have some files moving to another server, so that is what is causing the failure. How can I get the scheduled job to run as a different user?

I just made a BIG, STUPID mistake. I deleted all the .resx and .aspx.vb files on my machine through Dreamwaver Test Server view! It will kill me to re-write all the code  .
I have recently re-built the project into .DLL file before deleting those files. Is there anybody know how to decompile .DLL file to get source code back????
I also find there is a tempporary folder "_vti_cnf" under my wwwroot/project folder. In this folder, there are .aspx.vb and .RESX files. However, .aspx.vb file only contains the information like :
vti_encoding:SR|utf8-nl
vti_timelastmodified:TR| 17 Oct 2005 16:58:30 -0000
vti_extenderversion:SR| 4.0.2.8912
Could anybody help me out???
Thank you in advance!!!!!

See http://www.aisto.com/roeder/dotnet/[^]and get Reflector.NET
It won't get your aspx pages back, but it will produce something that looks sort of similar to your original source code.
Also, it might be a good time to consider the benefits of backing up your work from time to time. You may also want to consider using a source control system even if you are working alone - It is a very good discipline and at anytime you can go back and see previous versions.

hi colin,
as i ear you talking about source control system, i'd like to ask you.
i've installed TortoiseCVS on my computer, at home (i work alone on my projects). for now, the server and the source files source controled are located on the same computer. but i don't really find out how to :
1. configurate the server,
2. inserting files to be source controled
since this is quite in my hand, i'll then try to use a deported server on another computer. i think the two points i was ask previously remain the same, with the exception that the server will probably not be configured the same way.
do you have any idea of how TortoiseCVS work, how this can be reached, or at least, any tutorial links to point me the right way ?
thanks in advance,
