General Connection To SQL Server... Done... Grids And Data Retrival ...ugghhh
Dec 13, 2005
Help!!! please!!!... I'm pulling my hair off... Having an external hosting for sql server is terrible for .net. Too many restrictions and they are not willing to help at all... I cannot connect directly, I have to do everything using strings. Honestly and it's a shame to admit it I never learned how to connect using strings, only using the wizard (upsizing DBs from Access to SQL Server)finally, after a month of trying I was able to connect to the database using a string like this:
Dim CS As String
Dim db_name, db_username, db_userpassword As String
Dim db_server As String
db_server = "blah,blah,secureserver.net" /yes, with them >:(
db_name = "DB##"
db_username = "***"
db_userpassword = "***"
Me.SqlConnection1.ConnectionString = "SERVER=" & db_server & ";DATABASE=" & db_name & ";UID=" & db_username & ";PWD=" & db_userpassword
I am probably not using it right but it's working to capture info using stored procedures but I've been trying to get my datagrids to connect and they are impossible... Any ideas? what would be the coding part of the datagrid/dataset/etc... connection? That probably means that I can't use the property builder or the dataset generator, right? Any ideas ? Thanks

Hy everyone,
I have a problem at pulling data on PDA using Sql Mobile 5 from Sql Server 2000.
It work s for most tables, except for two . Every table of those two has about 1000 records and every record about 150 bytes, so all data is about 150 kbytes.
When I connect to the Sql Server 2000 through LAN, no problem. But when I connect through GPRS - VPN, the error occurs. But, the PDA- phone connection is via Bluetooth and at ping no TimeOut appears, the replies are about 600-700 ms. When connecting with a desktop computer through GPRS no such problem occurs.
So , I don't know what could be the cause: the connection or the Sql Mobile which doesn't retry enough in case of error to transfer all data .
A specialist from the GPRS provider told me to use 3G phone , but , because the GPRS phones have already been bought, this would be a too big investment. So, I don't think this is a good idea in this moment .
I found similar problem on the net and a solution was to use Pooling = False. But , in Sql Mobile there is no pulling parameter available when making the connection string .
Any help is very precious to me ,
Mihai .

Could someone give me the general syntax to pull xml data from a web server that I have access to? I do know that I can not use an ip address, I have to use the hostname, etc.
I was using something like
FROM OPENROWSET(BULK '\SERVERNAMESHAREPATHDATAFILE.XML', SINGLE_BLOB) as x
instead of using SERVERNAME I am user http:\www.mycompanyname.commycompanynamestoredata.xml
I do not understand why this does not work. I hope I gave enough information for this.
Please help.
Thank you

Hi
I am just starting to learn how to use data mining with SQL server 2005. I have some general questions which I hope someone out there can help me with.
Each month I have approx. 100.000 customers who buy a product.
I want to contact 10.000 of these with a letter for cross-selling some additional products.
Currently I choose these 10.000 randomly from the 100.000 customers. I now want to use SQL server 2005 data mining to choose these 10.000 better, to receive a better response rate. How do I transfer this knowledge to the 100.000 (potential cross-selling customers)
I understand that it could be set up in SQL server like the following:
case table: customer_id, gender, age, city, etc.
nested table: customer_id, product
Is this the way it should be approached and is there a special model/algorithm for this purpose?
Regards,
Dennis

We have a SQL 2005
clustered server (Microsoft Cluster Services) that is queried from 4 IIS6
Windows Server 2003 frontends. Each frontend runs both classic ASP apps
connection with SQL Server ODBC and .NET2 apps connecting with
System.Data.SqlClient. Ocassionaly we get a string of errors/timeouts opening a
connection lasting maybe 2 minutes.
One the classic ASP
apps we log one of these two errors:

or

On the .NET2 apps we
log

period elapsed prior to completion of the operation or the server is not
responding.

Hi!
I have stored prosedure with only one parameter - date to retrive data by datetime column (that includes date and time (h:min:sec) portions).
This query doesn't work when I try to select using LIKE operator
by date portion
select * from <table>
where <datecolumn> LIKE '20011206%'
BOL says:
It is recommended that LIKE be used when you search for datetime values,
because datetime entries can contain a variety of dateparts. For example,
if
you insert the value 19981231 9:20 into a column named arrival_time, the
clause WHERE arrival_time = 9:20 cannot find an exact match for the 9:20
string because SQL Server converts it to Jan 1, 1900 9:20AM.
A match is found, however, by the clause WHERE arrival_time LIKE '%9:20%'.
WHAT should I do?
Thank you,
Elena.

Ananth writes "A new feature is established in SQL Server 2005. That is Partitioned Table. I went through several articles in net regarding partioned table. But I did not get any generalized version of Partitioning.
For example I partitioned a table into 4 Filegroups based on Transaction Date. So I used range function to give ranges for 4 quarters of one year. It works fine. But I would like to generalize this scenario. It will work for one year. If new year comes ,I have to write new script and execute the same.
The Partitioned function should work for 12 months in a given year. So here year is the paramter and then that function should be construct based on the year automatically.
Can anybody give me answer asap."

Hello everyone, this post will be a bit lengthy, so please bear with me. I've been programming asp.net for abou 2 years. I'm not a master by any means, and I do things like I learn from books. Here is my standard way of connection to my mssql database (which is on the same server as my site, so I just use "localhost") Dim objConnection As New SqlConnection(Application("dbstring"))
Dim strSQL As String = "SELECT * FROM myTable WHERE this='that'"
Dim objCommand As New SqlCommand(strSQL, objConnection)
Dim objDataReader As SqlDataReader
objConnection.Open()
objDataReader = objCommand.ExecuteReader()
Do While objDataReader.Read() = True
'Do what I need to do with the data
Loop
objDataReader.Close()
objConnection.Close()
objConnection.Dispose()Here's my issue. Our website gets this error 2-4 and as many as 6 or 7 times a day: General network error. Check your network documentation.Line ###: objConnection.Open()I use the method I wrote above for getting data on almost every page in the site. Its a HUGE site, but I've made sure that I close all my connections. This is my global connection string: Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs) Application("dbstring") = "Server=WWW1;database=###;uid=#####;password=#####;Connect Timeout=300;Connection Reset=False;Pooling=False;Max Pool Size=75000;" End Sub Here's my web.config file:<configuration> <system.web> <customErrors mode="Off"/> </system.web></configuration>... This server has only one website running on it, its a dedicated server. Is there something in my code causing this error to happen so much? We have to restart the sql server everytime this error happens for it to go away. Its very disruptive to the website.

Hi All,
Great forum y'all have going here.
Just wondering if anyone else has experienced this?
Enterprise Manager:
I have setup and 'sucessfully tested a MAPI session' with a mail profile via support services > sql mail. That works fine, however in sql server agent properties the mail session section on the first general tab appears to be greyed out.
scenario is:
Windows Server 2003 SBS edition
SQL Server 2000 SP3
Exchange Server 2003 is also running on the server, with Outlook 2003 client (so i suspect side chaining issue).
Any help appreciated! did not have any luck googling or using microsoft KB.

I am working on two versions of an application, one of which will be awindows forms application (which will need to be redistributable) andthe other will be a web application.I have MS Visual Studio 2005 (along with the developer's edition of MSSQL Server), but not MS Access. I also have MySQL, PostgreSQL, Sun'sapplication server, Tomcat and Apache web server. I am working onWindows XP Pro, and have installed the .NET 3 SDK and all relevantrelated products I could find (e.g. 2 extensions packages for VisualStudio).I have one MS Access database, to which my users should have read onlyaccess. I have, and have used, a tool for importing MS Accessdatabases into MySQL. I expect that SQL Server has a similar utilityhidden somewhere (where I haven't yet looked, though I HAVE beenlooking - obviously in the wrong places). I have located a similarutility for importing MS Access databases into PostgreSQL. I have notyet decided which servers to use for the web version, but that isanother story, for which I may raise another thread in due course (butI welcome suggestions which may reduce the effort required givenrequired effort for the windows forms app).My problem is for the windows form aplication (intended for use by asingle family). I expect to use ADO.NET. The question is, should Iimport the Access database into MS SQL, and redistribute it, along withMS SQL Server Express (or is that necessary), or distribute it just asan Access database and use the jet engine to access it. A relatedquestion is, "Does ADO.NET support creating new databases for a givenengine?" Imagine a recipe database. It is easy enough to create a SQLscript that creates all the required tables, indices, foreign keys,&c., but can I submit that SQL script to an ADO.NET object, along witha file name, and have it create, e.g., an Access database with thesupplied name. Or do I have to create a database file with nothing init other than the schema?I have more questions, but they'll have to wait.ThanksTed

I have asp code that uses C# to create a SQL connection and a command. Then I create a data set and fill the data set using my comand. Finally I bind my data set to a data grid named myDataGrid. I am not sure where myDataGrid comes from since it is never defined. Where does myDataGrid come from? Also, I believe that I do not need to call page_Load since auto wire is set to true by default so it is my understanding that this method page_Load will be called by default.void page_load(object sender, EventArgs e) { SqlConnection myConnection = new SqlConnection("server='(local)'; trusted_connection=true; database='mattsDEMO'"); SqlDataAdapter myCommand = new SqlDataAdapter("select * from people", myConnection); DataSet ds = new DataSet(); myCommand.Fill(ds, "people"); MyDataGrid.DataSource=ds.Tables["people"].DefaultView; MyDataGrid.DataBind(); }
When I place a data grid controll on my page named myDataGrid, I do not see a data grid and there is no data either. The code in the HTML looks like this:
<body> <form runat="server"> <p> <asp:DataGrid id="myDataGrid" runat="server" BorderColor="Maroon"></asp:DataGrid> </p> </form></body>I tried using debug that comes with the .Net framework (since I am using Web Matrix) but I get an error saying no symbols were found for this document when setting break points. What are symbols and why do I need them?So, I basically have four (4) important questions that I need help answering: 1) Why do I not have any data in my data grid? 2) Where did myDataGrid come from? 3) Is the page_Load method called by default if auto wire is set to true or not declared? 4) Why do I need symbols for debug?Below is all my code in one complete view:<%@ Page Language="C#" %><%@ Register TagPrefix="wmx" Namespace="Microsoft.Matrix.Framework.Web.UI" Assembly="Microsoft.Matrix.Framework, Version=0.6.0.0, Culture=neutral, PublicKeyToken=6f763c9966660626" %><%@ import Namespace="System.Data" %><%@ import Namespace="System.Data.SqlClient" %><script runat="server">

DataSet ds = new DataSet();myCommand.Fill(ds, "people");
MyDataGrid.DataSource=ds.Tables["people"].DefaultView;MyDataGrid.DataBind();}

Well, what I want is to be able to do some tooling on a database (.sdf) on my WM5 device using C# Express 2008.
The problem is that when I select the "Tools/Connect to database" option, I choose my data source to be "Sql Server Compact 3.5" in the next screen, and when I press Continue, I am taken to the next screen, and here I cannot select the "ActiveSync connected device" in the "Data Source" section...it is disabled. The only option is selecting "My computer"...but I do not need that.
Is there something I need to install in order to activate that option?
Thanks,

Hopefully there's an easy answer for this. I'm totally new to SQL server and I'm trying to upsize an Access database. Whether I use the upsizing wizard or try to create a data source through the ODBC Data Source Administrator, I get a connection failed error. It tells me the server does not exist or my login is incorrect. I'm using NT authentication to connect to the server on my local drive. I just installed the whole 2005 express edition and the only thing that came up during the install was that I didn't have IIS installed. I didn't see how that would be relevant, so I went ahead with the install.
Shouldn't this work with the default setup? I've searched around trying different "solutions" although I doubt they were specifically related to this very basic problem. I tried giving my login every right I could find through in the database engine properties in the server management studio, which connects fine itself with just my network login name and no password. What am I missing?

We just replaced an older Windows 2000 sp4 server with a new Window 2003 Standard Edition sp2 server to run our batch processing. We noticed that when the SQL command times out we now get the following error in the ADO command object error collection.
[DBNETLIB][ConnectionWrite (send()).] General network error. Check you network documentation.
Native Error: 11
SQL State: HY018
msado15.dll version 2.82.3959 is on this server.
On other servers running Windows 2003 Enterprise Edition sp1 the error on the ADO command object is normal with.
Timeout expired
Native Error: 0
SQL State: HYT00
msado15.dll version 2.82.1830 is on this server.
The SQL server they are talking to is on the other side of a firewall. It is SQL 2005 sp2 running on Windows 2000 sp4.
I have also tested this on a Windows 2003 sp2 server that doesn't have to cross a firewall and get the correct Timeout error. It also has the same version of msado15.dll as problem server.
The application is a collection of VB6 Components that are running in COM+ applications. I have isolated the test application to our one SQL interface component and have build a test vbs that can reproduce this on demand. The VB6 Components were not modified in any way for this change and have been working fine for many years prior to this.
All other aspects of our batch processing works as expected. Transactions are working fine. As long as the SQL doesn't timeout everything is normal. DTCPing was used to ensure both servers have correct ports open to allow DTC traffic. Checked the SynAttackProtect setting on SQL and this is not an issue since other clients have no problems.
One point I would like to add is that this new server was initially setup with a temporary server name and then was changed to use the name of the original server on move day. Don't know if this has any impact or not.

Hello,
I've created a SSIS Solution and have created Data Sources. I have two packages. One was created before the Data Sources, and one was created after. The package that was created after is using connections from the Data Sources. I want to change the package before the Data Soruces were created to use them, but when I right click in the Connection Managers pane "New Connection From Data Source.." is not an option.
Did I not add it to the Solution properly?
How do I get it to show?
Did I not refresh something?
Please provide the how if you figure it out.

Server Error in ' 'Application.
An error has occurred while establishing a connection to the server.
When connecting to SQL Server 2005, this failure may be caused by the fact that
under the default settings SQL Server does not allow remote connections.
(provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance
Specified) Description:
An unhandled exception occurred during the execution of the current web
request. Please review the stack trace for more information about the error and
where it originated in the code. Exception Details:

We've been using SQL Server 2005 for a while as the db for our web app. Everything has been working fine, until yesterday when we started getting a "Arithmetic operation resulted in an overflow. (System.Data)" error message when trying to connect from SQL Server Management Studio or from our web app. This only happens when trying to connect remotely, although remote connections have worked for us perfectly in the past. The full error message is reproduced below. Thanks ahead of time for any help. ===================================Cannot connect to serverName===================================Arithmetic operation resulted in an overflow.
