ConnectionString is below.
Dim objDb As New SqlConnection("Data Source='(local)';trusted_connection=true;Initial Catalog=classdb")
This ConnectionString occurs DB-Open-Error. Why?
Show me the Solution.
How do i know whether the connection is open with the sqlserver database while work in the application?
View 2 Replies View RelatedI have a sql server project where I have added 1 stored procedure (named StoredProcedure1) and 1 class (named MyClass). MyClass has two functions Func1() and Func2(). The stored procedure simply instantiates MyClass and calls Func1().
Func1() creates a SqlConnection object using "context connection=true" - opens the connection and then calls Func2(). Func2() also creates a SqlConnection object using "context connection=true" - and attempts to open the connection. However when attempting to the Open() call inside Func2(), the code just exits. What gives? The code is pasted below, thanks!

View 4 Replies View RelatedI have a problem where my connection always has an open transaction as viewed by activity monitor.
I am using the latest MS SQL Server 2005 JDBC driver (1.1) and connecting to SQL Server 2000.
This issue arises only when selectMethod=cursor and autoCommit is set to false. This issue does not exist when I connect to SQL Server 2005.
Has anyone else seen this issue?
How can this issue be resolved?
Thanks

I am getting the above error when I try to create Notificatioin services new Instance.
Additional Information is
Failed to connect to server ABC(Microsoft.SqlServer.ConnectionInfo)
An error occured while establishing connection to the server.When connecting to SQL Server 2005, this failure may be caused by the fact that under default settings SQL Server deoes not allow remote connections.(Provider : Named Pipes Provider, error 40 -could not open connection to SQL Server)(Microsoft SQL Server error: 53)
Please help me I am new to SQL Server 2005.I can't able to proceed.
I get the below error only when my IDE open. It connects well when it is found closed.
[SqlException (0x80131904): Cannot open user default database. Login failed.Login failed for user 'JPASPNET'.]
I could solve this by giving the logged in windows user to impersonate under IIS window > WEBSITE > ASP.NET tab > EDIT CONFIG > APPLICATION tab
But I wish someone could give me the proper solution.
I almost tried all from giving ASPNET user as a administrator to configuring the same in Express management tool.
Environment: XP pro, VWD and SQL Express
Hi there,
I got an approach like that:
1) Read something from DB - check the value, if true stop if false go on2) Read the second Value (another SQL Statement) - check the value etc.
Now I could open the connection at 1) and if I have to go to 2) I leave the connection open and use the same connection at 2). Is it ok to do that?
The other scenario would be opening a connection at 1), immediately close it after I read the value and open a new connection at 2).
Thanks for the input!
Post installation of SQL Server 2014 Express edition, I am able to connect to the Database Instance.
But while opening a new query window in SSMS or opening a table getting the error:

We have a static class that makes an HTTPWebRequest to get XML data from one of our vendors. We use this as input to a stored proc in SQLServer2005. When I compile this class and call it from a console application in visual studio it executes in milliseconds, everytime. When I compile it, create the assembly and clr function and execute it in SQLServer, it takes around 14 seconds to execute the first time, then on subsequent requests it is again really fast, until I wait for 10 seconds and re-execute, once again it is slow the first time and then fast on subsequent requests. We do not see this behavior when executing outside SQLServer. Makes me think that some sort of authentication is perhaps taking place the first time the function is run in SQLServer? I have no idea how to debug this further. Anyone seen this before or have any ideas?
Here is the class:
Code Snippet
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;
namespace Predict.Services
{
public static class Foo
{
public static string GetIntradayQuote(string symbol)
{
string returnQuote = "";
HttpWebRequest request = (HttpWebRequest)(WebRequest.Create("http://data.predict.com/predictws/detailed_quote.html?syms=" + symbol + "&fields=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,28,30"));
request.Timeout = 1000;
HttpWebResponse response = (HttpWebResponse)(request.GetResponse());
StreamReader streamReader = new StreamReader(response.GetResponseStream());
returnQuote = streamReader.ReadToEnd();
streamReader.Close();
response.Close();
return returnQuote;
}
}
}
When I run call it from a console app it is fine.
I compile it into a dll and then create the assembly and function as follows:
Code Snippet
drop function fnTestGetIntradayQuoteXML_SJS
go
drop assembly TestGetIntradayQuoteXML_SJS
go
create ASSEMBLY TestGetIntradayQuoteXML_SJS from 'c:DataBackupsCLRLibrariesTestGetIntradayQuote_SJS.dll' WITH PERMISSION_SET = EXTERNAL_ACCESS
go
CREATE FUNCTION fnTestGetIntradayQuoteXML_SJS(@SymbolList nvarchar(max)) RETURNS nvarchar(max) AS EXTERNAL NAME TestGetIntradayQuoteXML_SJS.[Predict.Services.Foo].GetIntraDayQuote
go
declare @testing nvarchar(max)
set @testing = dbo.fnTestGetIntradayQuoteXML_SJS('goog')
print @testing
When I execute the function as above, again, really slow the first time, then fast on subsequent calls. Could there be something wrong with the code, or some headers that need to be set differently to operate from the CLR in SQLServer?

Skipper.
Hi experts;
I have a problem with unicode character 0x2300
I created this table
create table testunicode (Bez nchar(128))
Insert Data
insert into testunicode (Bez)values('Œ€„¢')
with 2 Unicode characters
Œ€ = 0x2300
„¢ = 0x2122
Selecting the data
select Bez from testunicode
I see
"?„¢"
„¢ = 0x2122 is ok but instead of 0x2300 there is 0x3f
When I modify the insert statement like that ( 8960 = 0x2300 )
insert into testunicode (Bez)values(NCHAR(8960)+'„¢')
and select again voila i see
"Œ€„¢"
Does anyone have an idea?
Thanks
I am trying to 'load' a copy of a SQLServer 2000 database to SQLServer 2005 Express (on another host). The copy was provided by someone else - it came to me as a MDF file only, no LDF file.
I have tried to Attach the database and it fails with a failure to load the LDF. Is there any way to bypass this issue without the LDF or do I have to have that?
The provider of the database says I can create a new database and just point to the MDF as the data source but I can't seem to find a way to do that? I am using SQL Server Management Studio Express.
Thanks!!

View 2 Replies View RelatedI have an app that uses a sqlserver 2000 jdbc driver to connect to a sqlserver 2000.
Is it possible to do a direct replacement of sqlserver 2000 with sqlserver 2005 express just by reconfiguring the app to point to the express? The app would still be using the sqlserver 2000 jdbc driver to try and make the connection.
If that is a possibility, what can be some differences in the configuration? Previously with 2000 the config information I entered is:
server name: "machinename"( or ip). I've also tried "machiname/SQLEXPRESS"
DB name: name of db instance
port: 1433(default)
user and pass.
My attempts so far results in
"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket."
and
"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Unable to connect. Invalid URL."
Hello,
I have an SQLServer Mobile database, and I would like to know if there is a way to upgrade it to SQLServer 2005 (.mdf) database. My database has no records in it, just the structure (tables etc). What I am actually asking is if I can create automatically a new SQLServer 2005 Database with the same structure as my existin SQLSErver Mobile database

Hello people.
I am in the process of planning a server upgrade to sql2005 x64.
I created 2 linked servers: one to a SQL2000 sp4 server and one to a SQL7.0 SP3.
I have the following error when I query the linked servers.
OLE DB provider "SQLNCLI" for linked server "IVDM2K" returned message "Unspecified error".
OLE DB provider "SQLNCLI" for linked server "IVDM2K" returned message "The stored procedure required to complete this operation could not be found on the server. Please contact your system administrator.".
Msg 7311, Level 16, State 2, Line 1
Cannot obtain the schema rowset "DBSCHEMA_TABLES_INFO" for OLE DB provider "SQLNCLI" for linked server "IVDM2K". The provider supports the interface, but returns a failure code when it is used.
I am aware of KB 906954.
http://support.microsoft.com/default.aspx?scid=kb;en-us;906954
I applied the instcat.sql on the SQL2000SP4 server and my linked server issues for that one are gone.
However, I ran the instcat.sql script on the SQL7.0 sp3 server and the linked server is still giving me an issue.
Can someone help me find a solution to this?
Regarding KB935356, is there a "post" service pack 2 update for SQLServer Express?
Thanks.
Hello Expert!
I have 2 Database €“ Access & SQLServer(ver 7)
I need to Import Data TblShift from Access to SQLServer €“ using DTS I€™ve done this successfully!
Now I want to use parameter so I only importing record within range (e.g. ShiftDate BETWEEN 05-24-2006 AND 06-23-2006)
In SQLServer, I have created table to store the date range as following:
TblParameter

How do I use the date range from TblParameter(SQLServer) to import record from TblShift(Access) using DTS?
Is this possible or any better solution for this?

Hi,
I am new to SQL Server 2005. I tried connecting to my local machine by using my machine name as Server name and then tried running the following query:
SELECT * FROM SYS.Objects. It gives me following error:
Invalid object name 'sys.objects'.
Whereas, if I connect to my local machine using mahcinenameSQLEXPRESS, then the above mentioned query runs fine.
Why is this difference? What is the difference when I login in these 2 different ways.
Any help would be appreciated.
Thanks in advance.

Just a quick question about connection management. My application willnever need more than 1 or 2 connections about at any given time. Also, I donot expect many users to be connected at any given time. For efficiency, Iwould like to keep connections alive throughout the lifetime of the objectsrequiring them, rather than opening a new connection, executing code andthen closing it again. What is the most efficient way of doing this?Should I perform the open/close or just one open when I create the objectand a close when I dispose of it?
