I have a dilemma which is completely and utterly baffling me...
We have a Classic ASP site which has been running for about a year, its powered via a local Win2008 SQL database (The SQL Express engine is on the same server as IIS). This is the connection string we currently use
Provider=SQLNCLI10;Server=SERVERNAME\SQLEXPRESS;Database=dbname;user id=username;password=password;
We now have a need to move the database to a dedicated DB server, and connect to it remotely - We restored the DB on the server, and checked everything looked ok (All data is present in all tables)
So we changed the server name to the IP address and was unable to get it to connect, in the end the only way we could get it to connect was using this connection string.
driver={SQL Server Native Client 10.0};server=IPADDRESS\SQLEXPRESS,1433;uid=user;pwd=password;database=dbname;
HOWEVER... Now it's randomly missing product names and SKU's and prices in the front and back end, even though the data is present in the DB AND it is REALLY slow to display the webpages? If I use the same DB locally with the previous connection string its fine and all data is appearing?
I know this DB server is fine as it powers other ASP.NET sites with via a remote connection and they are very fast to connect?
Any hints... or help on why this new connection string is causing problems with reading data from the DB???
To update the native client on the web server to the most recent public version, go here:
http://support.microsoft.com/hotfix/KBHotfix.aspx?kbnum=2567714
Check the box for "2008R2_SP1_SNAC_CU2_2567714_10_50_2772_x86" if your web server is an X86 machine, and "2008R2_SP1_SNAC_CU2_2567714_10_50_2772_x64" if it is 64-bit. Enter your e-mail address, fill in the captcha, hit "Request hotfix" and the download link will be e-mailed to you. Download it to the web server, run the installer (using the password sent to you in the e-mail) and restart the web server. Now try your original connection string again.
EDIT
Adding some other sample connection strings that I have used in the past (I've been a classic ASP guy since the 90s, founding and writing 95% of the content on aspfaq.com, including this article on connection strings). As requested in a comment to the original question.
Note that "srv" could be IP address, or localhost, or servername, or . and it could be followed by \INSTANCE_NAME (e.g. \SQLEXPRESS). I would try them in this order, and pay attention to the parameter names as well as the values - you seem to mixing modern parameter names (e.g. Provider) with less modern ones (e.g. Database).
Provider=SQLNCLI10;Data Source=srv;Initial Catalog=db;User ID=user;Password=pwd;
Provider=SQLOLEDB.1;Data Source=srv;Initial Catalog=db;User ID=user;Password=pwd;
Provider=SQLOLEDB;Data Source=srv;Initial Catalog=db;User ID=user;Password=pwd;
Driver={SQL Server};Server=srv;Database=db;UID=user;PWD=pwd;
Sometimes if you are having issues with Named Pipes or Shared Memory it can help to enforce TCP/IP by adding the following parameter:
NETWORK=DBMSSOCN;
You can get a lot more information over at Carl Prothman's site or ConnectionStrings.com. They no longer cater to classic ASP specifically, for obvious reasons, but you can still glean a lot of information from the samples they provide for other languages.

I'm writing a new project that utilises MySQL , There is no problem with the app I'm working on, but when the app recives the output from my sql server it immediately rejects it as null. When accessing my SQL server on port 3306 I am getting strange garbled messages back as well as the short message 'packets out of order.' In my setup I have, MAMP, Docker, Apache server and PHP. I can access each service on its respective port just fine.
1) I have looked into this by running console in the browser which reports the text being incorrectly formatted to something that isn't utf-8
2) I have followed this guide
https://medium.com/#manish_demblani/breaking-out-from-the-mysql-character-set-hell-24c6a306e1e5 and the results that my sql server have churned out are as follows
enter image description here
My question is this. Why is MySQL set up in this strange fashion? Why is it presenting in CP850 /DOS/ Latin? Are there no defaults/config files to change or is it done through windows somewhere
It seems you somehow messed up the client configuration (connection string, [client]-section of your cnf file (on the system that you started the mysql console on), ...). It tells your server to send data in cp850. Not sure why you would get packets out of order, maybe you have an additional underlying problem (very old library maybe?), but I'd start there. It's unclear: did you follow the blog post and then had problems, or was that a solution attempt? In any case, try to focus your attention on the client. Try to undo changes you made. MySQL uses utf8 by default for a long time now. – Solarflare
Background on the MySQL database: it was created from a Wordpress website. As far as I know, it can only be accessed through PuTTy with the ff credentials given to me by my client who I’m making the app for:
hostname
port
my username to get into server
my password to
get into server
mysql username
mysql password
It says from multiple sites that this is the PHP syntax to connect Android to MySQL
// Connecting to mysql database
$con = mysql_connect(DB_SERVER, DB_USER, DB_PASSWORD) or die(mysql_error());
It does not work and when checked for the connection error, it shows the error “Connection timed out.” when I put credentials needed (hostname, mysql
username and password). I’m assuming it’s because I need to get into the server first (with credentials #3 and #4).
Is there a workaround to this?
EDIT:
This is only based on the assumption that I am supposed to create a PHP file (that I will place inside a Jave file in Android Studio) to connect to their database. Are there other ways to connect to a private server?
Welcome Ateshi!
It sounds like you want an android app to directly access the mysql database that holds the content of a wordpress website.
The MySQL database server is most likely not publicly available on the internet for good reasons (security), as per this answer
You have posted some PHP code. PHP usually runs on the server alongside mysql, it not usually run on android.
Here is how you usually set up something like this:
Your android app makes a web request to http://yourexampleserver.com/example.php
Inside that example.php which is on the server, you have the PHP code that then does:
connects to mysql (with local credentials)
perhaps writes to the database
perhaps queries the database
formats the results into a useful format like JSON
The results are returned to java on your android which then usually shows them in the UI etc
This whole process is usually described as building a "webservice" for the app to use.
If however, you want the database contents to be stored offline and locally on android, then you probably need to connect to the server manually, export the database and download it, and then include it in your android project.
First and Foremost, I know zip, zilch, nada, about VBA, access, and Advantage database Server.
I have a PC in one location that can connect and update with an Access 2010 file where every drive is mapped, e.g. \file\whatever
The advantage streamlinesql odbc dsn's were setup as such \file\whatever foxpro
Now, the PC has been moved to a new location (the company moved) and there is a vpn connection between the two locations (the data server is still located in the old location and cannot be moved), and so the new map would look like this: \xxx.xxx.xxx.xxx\file\whatever
However, Access cannot connect so that it can run its process and update the files it needs to.
I do not know the actual code to place here to help with fixing this, so answering this question with more is fine with me.
I can say that the vpn is built with sonic wall.
The first thing I would try is to connect with ARC32 (The ADS query tool), since you can then rule out ODBC and Access as the problem.
ADS has three connection types:
local
remote
internet
When you directly connect to an Advantage Database Server via TCP/IP, you want the remote connection type.
The connection type can usually be set via the ads.ini file, which also must contain the IP address and port for the ADS server:
[SETTINGS]
ADS_SERVER_TYPE=2
[MYDATABASE]
LAN_IP=10.20.1.20
LAN_PORT=6262
For more info about ADS.ini see the official documentation:
http://devzone.advantagedatabase.com/dz/webhelp/Advantage12/master_ads_ini_file_support.htm
When you try connection over ODBC maybe a complete reference of the connection options would be useful, I have written them down here:

I'm building a website with EF4.1 and MVC3 (C#). Trying to find out what the proper way to remove the password from the connection string is. I've done some searching and can't seem to find anything that tells how to remove the password from the connection string.
I'm actually working on two different sites at the moment. One is hosted on GoDaddy and is using their SQL Server db. The other is hosted here at work and will be using SQL Server 2005.
Lastly, is it possible to do the database first code generation with a MySQL database? I'm personally more comfortable with MySQL and prefer it to SQL Server, but have had issues getting this to work.
If you should need any additional information please let me know.
You should probably encrypt your web.config connection strings before deploying it to the server.
AFAIK, if you connect to your server using SQL Server Authentication, the connection string needs the username and password. If your app and db servers had domain trust, you can use integrated mode / windows authentication / identity impersonate to have a password-less connection string. But most service providers don't let you do this -- they use SQL Server Authentication to keep customers out of their domain.
Either way, there is more sensitive information in the connection string than just the password. You should encrypt the whole <connectionStrings> node.
When I publish my project clients will need to be able to setup the initial configuration, and part of that is the Sql Database Connection. I have an instance of Sql Server 2008 running on my system (MSSQLSERVER2008) as well as SQLEXPRESS2005. I am trying to use the following connection string locally just to see if this works, and I can't get it to work:
ConnectionString = {Data Source=127.0.0.1;Initial Catalog=DCOMProductionsDesktop;Integrated Security=False;User ID=DCOMProductionsDesktopService;Password=;Network Library=dbmssocn}
The error I get is the usual "The target machine actively refused the connection".
*There isn't any firewalls running, and its inside the network anyway
*TCP/IP Protocols are enabled
*Remote Connections are enabled and permitted
So, I'm stumped.
Edit
I changed the connection string's data source to:
DataSource=192.168.0.2\MSSQLSERVER2008 on my WinXP VM (for testing remotely)
Now, this did work. But when I deploy this across the internet, will that same connection string work for clients outside my network using a domain name such as:
DataSource=desktop.dcomproductions.com\MSSQLSERVER2008
Or will I need to do something different?
It will work, as long as "desktop.dcomproductions.com" or whatever, resolves to the proper IP address. So that name should be set up either on the public or private DNS properly.
Also, make sure it resolves to a public/external IP address, unless your client's scripts are going to be within the same network as the SQL server.
Thought I post it as an answer, instead of comments :)
It's been a while sice I used anything but Named Pipes to connect to a sql server instance so this may not be relevent but try changong Data Source to Server.
They may be synonyms, as I said, it's been a while.
Also, even if you are using an IP address, you aren't specificying an instance of sql server to connect to, that may also be causing issues
