Hi,
Thank you your suggestion.
I tried to change configuration manager for enabled TCP/IP. Again the following error returned
"[Microsoft][ODBC SQL server Driver][TCP/IP Sockets]SQL server does not exist or access denied"
Thanks in Advance

I want to use the text from a textBox in webform1 as input parameter in a SQL query on webform2. I'm building a website where customers can watch their unique information pulled from a SQL database. Anyone with a good idea? Thank you 
Petter

Have you solved this problem?

I have a problem with my c# application. I am using a MySql Database Server, and I make a connection every time I have to make a query. I noticed that this is the cause why my application is so slow. I have done only one connection for all queries and after a while the server kills my connection. What can I do?

It's not much of an answer, but when I program against Sql Server I do the same thing and open a connection each time I want to perform and action. This way you only have a connection formed when it's needed. The performance of this has always been fine.
Can you quantify slow? Are we talking a few extra milliseconds or a few extra seconds?
Which ado.net provider are you using?
Are you running the DB locally? Over a network? over the internet?
Note: I've not programmed against mysql so I probably wont be able to answer, but these extra answers will help others help you with the problem.

I forgot to mention that I'm using a mysql driver for c# not a ado.net and the db is running over the internet.
The application is very slow, I'm talking about a few extra seconds per operation with db. And for now the db is not very large.

hi..
How many users can connect SqlServer2005 express edition at a time?

http://msdn2.microsoft.com/en-us/library/ms345154.aspx[^]
The SQL engine supports 1 CPU, 1 GB RAM, and a 4 GB database size. This mechanism permits easy differentiation from other SQL Server 2005 editions by having well defined cut-off points. Otherwise, there is no workload throttle and the engine performs as in other editions. There is no hard-coded limit to the number of users that can attach to SQL Server Express but their CPU and memory limits impose practical limits on the number of users that can achieve acceptable response times from a SQL Server Express database.

Why have you posted this question in the SQL forum when it is clearly a C# question?

Hi i have one query this is giving o/p:
But Probs is its taking long time to produce the o/p:
any one give me the solution to fetch quickily for the below query:
My query:
Select CO_NAME,Sector,Analyst,edate,CurrentSector,CurrentConSec,Sec_Recomm,Sec_Confidence,CurrentMarket,
CurrentConMark,LastMarket,LastConMark,ClosingMarketPrice AS ClosingPrice,
CurrentClosingMarketPrice AS CurrentClosingPrice,
((CurrentClosingMarketPrice)/(ClosingMarketPrice)) AS Performance,AnnId
from
(SELECT first 100 MASTER.CO_NAME, NewCompany.Co_Name AS Company, SectorMaster.Sector_Name AS Sector,
UserMaster.UserName AS Analyst, AnalystViews.DOE AS edate, AnalystViews.Sec_Recomm AS CurrentSector,
AnalystViews.Sec_Confidence AS CurrentConSec,
(SELECT first 1 Q.Sec_Recomm FROM AnalystViews Q ,MeetingSchedule INNER JOIN MeetingSchedule M ON
Q.AnnounceId = M.AnnounceId WHERE (Q."ACTIVE" = 'T') AND (Q.Completed = 'Y') AND
M.CO_CODE = MeetingSchedule.CO_CODE ORDER BY Q.DOE) ,
AnalystViews.Sec_Confidence,AnalystViews.Mark_Recomm AS CurrentMarket,
AnalystViews.Sec_Confidence AS CurrentConMark ,AnalystViews.Mark_Recomm AS LastMarket ,
(SELECT first 1 Q.Sec_Confidence FROM AnalystViews Q ,MeetingSchedule M INNER JOIN
MeetingSchedule ON Q.AnnounceId = M.AnnounceId WHERE (Q."ACTIVE" = 'T') AND (Q.Completed = 'Y') AND
M.CO_CODE = MeetingSchedule.CO_CODE ORDER BY Q.DOE) AS LastConMark ,
(SELECT first 1 "CLOSE" FROM DLYPRICEBSE ,MeetingSchedule ,AnalystViews
WHERE (DLYPRICEBSE.Co_Code = MeetingSchedule.Co_Code) AND (DLYPRICEBSE."DATE"<= AnalystViews.DOE)
ORDER BY DLYPRICEBSE."DATE" DESC) AS ClosingMarketPrice,
(SELECT first 1 "CLOSE" FROM DLYPRICEBSE ,MeetingSchedule WHERE
(DLYPRICEBSE.Co_Code = MeetingSchedule.Co_Code) ORDER BY DLYPRICEBSE."DATE" DESC) AS CurrentClosingMarketPrice,
AnalystViews.AnnounceID AS AnnId FROM MASTER RIGHT OUTER JOIN NewCompany RIGHT OUTER JOIN
MeetingSchedule ON NewCompany.Co_code = MeetingSchedule.Co_Code ON MASTER.CO_CO

Look at the execution plan produced by SQL Server for your query. Identify those parts of the query that are consuming a disproportionately large amount of the query batch time and try and optimise them.

Hi Magi
Which database engine is this for? Informix?
Try getting the individual sub-queries to work separately. For example:
(SELECT first 1 Q.Sec_Confidence
FROM AnalystViews Q, MeetingSchedule M
INNER JOIN MeetingSchedule
ON Q.AnnounceId = M.AnnounceId
WHERE Q."ACTIVE" = 'T'
AND Q.Completed = 'Y'
AND M.CO_CODE = MeetingSchedule.CO_CODE
ORDER BY Q.DOE) AS LastConMark looks like it is supposed to be a correlated sub-query (and should link back to the outside query). It is probably doing lots of work that you don't want it to do (and I guess is returning the wrong answer).
In this case, I would expect at least one of the links to the MeetingSchedule table to be removed. Possibly:
SELECT FIRST 1 Q.Sec_Confidence
FROM MeetingSchedule M
INNER JOIN AnalystViews Q
ON Q.AnnounceId = M.AnnounceId
AND Q."ACTIVE" = 'T'
AND Q.Completed = 'Y'
WHERE M.CO_CODE = MeetingSchedule.CO_CODE
ORDER BY Q.DOEWhich you could test by replacing "MeetingSchedule.CO_CODE" with an appropriate code.
Hope this helps.

Standard SQL 2000 code will work as well as ODBC.

simply all i want to do is to make this expression works : DataSet.Tables["Accounting"].Columns["Total"].Expression = "Income - Spends";
this i put in the form load but when i try to complie vs 2005 gives me some crap error which i dunno what does it means (The column mapping from SourceColumn 'Total' failed because the DataColumn 'Total' is a computed column) i dunno what exactely it requires to do my simple math operation on the database and return me a decent value..and if this way is wrong what is right to do it..i hope someone get to me as fast as possible..thanx!

Please read the forum guidelines. Giving your messages titles like 'help' or 'urgent' gives us no idea what the problem is and will get you ignored.

I'm urgently ignoring it.;P

I try to be helpful, but after 12 hours and no response to my request for clarification I can see that it isn't really that urgent.

The original post must not be really that urgent after all. Putting in "urgent" must have just been bait to get someone to reply right away.

That doesn't read like a compiler error to me. The compiler doesn't know anything more about DataSets, DataRows and DataColumns beyond the fact they are classes - so a high level error that indicates semantic knowledge of the classes it is using is virtually impossible to come from the compiler. I can't actually see how the compiler could pick up on this error as the fact that "Total" is computed can't really be known until run time.
So, where did this dataset come from? How was it created? What filled it and with what?

database columns supposed to be filled by the interface user \,and the error was in the calculated columns i want to enter a number qand another one and substract from each other to get me the last empty column...it's a simple thing i know but i was sick of it,and all those people who bothered to reply with silly things i will just ignore you ! so mature you are !! (give me one person who reads any instructions on forums,except you ofcourse)...

There are enough forum guidelines around the world that you must have picked up on one or two of them... Curiously, the all say very similar things.
