Connecting web app to SQL Server on Azure VM - sql

I have a SQL Server on Azure VM and I am trying to connect to it from my web app. Can someone point me in the right direction?
I have searched and I have not found one where it connecting to SQL on VM (iAAS). I have only seen tutorials connect to the SQL Server (PAAS). Any help appreciated.

SQL Server on an Azure VM is exactly the same as connecting to SQL Server on a physical server or a VMWare VM.
You will need to ensure that the VM has either a static IP Address or a DNS name. This is what you would use to connect to it from your client. You will also have to ensure that you deal with firewalls.
Is your client also an Azure VM or is it on-premises?

Here's two Azure documents may help you:
Connect to a SQL Server Virtual Machine on Azure.
This topic describes how to connect to your SQL Server instance running on an Azure virtual machine.
Connect your application to Azure SQL Database managed instance.
Today you have multiple choices when deciding how and where you host your application.Whatever choice you made, you can connect it to a Managed Instance.
Hope this helps.

SQL Server Developer Clustering Limitations?

Hi we're building out some test clusters in Azure, using Developer edition of SQL Server 2016. However with no firewalls between the two nodes, both nodes in same subnet, all tcp/ip settings enabled and sa permissions on both servers we're unable to connect using SSMS (management studio), what I'm trying to understand is are there any limitations with creating AlwaysOn Availabiity groups using SQL Developer 2016? Getting the following error
Mcrosoft SQL Server, Error 5 "Access is Denied"
However I can log onto the instances on both machines locally using ssms, but not across the network.
Think it might be a limitation on the sql server edition?
Thanks and sorry if this seems a bit random :)
In order to connect to SQL server on VM from a local machine. you have to not only open 1433 port for the VM on the portal, but also do you need to set up the firewall inside of the VM machine. Make sure you have the inbound 1433 port opened as below:

Cannot connect to Azure SQL database, even with whitelisted IP

I am currently unable to connect to my Azure SQL database from a separate remote standalone dedicated box in a private datacenter.
I have an Azure SQL database where I manage the list of IP addresses that can connect to this database. This has worked perfectly until now. I have recently set-up a new dedicated box in a private datacenter that needs to query the Azure SQL database at regular 5 second intervals, give or take.
The problem is, this dedicated box cannot establish a connection to the Azure SQL database, despite being able to connect to other remote FTP servers, MySQL servers, etc. The Azure SQL database does have the IP address of the dedicated box on the allowed connection list. Furthermore, I temporarily opened up a massive range of allowed IP addresses (0.0.0.0 -> 255.255.255.255) on the Azure SQL database to see whether this inability to connect may have resulted from IP blocking.
Does anyone have any suggestions or thoughts on what might be causing this and how I could begin debugging the situation better?
To clarify: I can connect to the Azure SQL database from laptops with individual IP addresses in my office and elsewhere, so long as they have been added to the database whitelist; I can make outward connections to remote FTP and MySQL servers from the dedicated box; I have tried to open-up a massive range of allowed IP addresses on Azure SQL with no luck.

To summarize.
Windows Azure SQL Database (formerly known as SQL Azure) works exclusively and only on TCP port 1433. It only support SQL Server Authentication, TCP connection and TDS protocol as of today.
In order to successfully establish connection to SQL Azure one must fulfil the following requirements:
Create SQL Azure server & Database
Setup SQL Azure Server's firewall rules to accept connections from the IP address of application that will connect to that server
Make sure the box (be it Virtual, or home, or whatever) has no blocking outbound TCP port 1433
Explicitly force encryption in connection string
Explicitly chose to not trust server certificate in connection string
Please note that many (if not all) ISPs (Internet Service Providers) and Hosters, as well as IT staff within companies DO block outgoing TCP Port 1433 due to the SQL Slammer worm. This outgoing port blocking appears to be one of the most faced issues of newcommers to SQL Azure.
UPDATE Nov. 2015
As of August 2015, there is preview feature that enables you to use Azure AD to authenticate to Azure SQL Database. You can read more on this new preview feature here: https://azure.microsoft.com/en-us/documentation/articles/sql-database-aad-authentication/
If you're using corporate network for internet access and facing this problem,
a simple way around this is to use your phone's mobile hotspot for internet access instead.
Be sure to disable your ethernet connection too, which may also be connected to the internet.
Spent hours on this issue. The fix for me was finally found to be my setting on the Xfinity firewall. I had it set to high. Once I changed the setting to low security, I could connect to the Azure sql database with no issues.

Unable to connect to SQL Server 2005 installed on Win7 virtual machine

I am not able to connect to a SQL Server 2005 hosted on a Win7 virtual machine. I am new to VM, can someone help me locate the problem?
I am able to connect another SQL server which is installed on the local machine.
When you say you can't connect - that can mean a lot of things - really you need to be much more specific.
In addition to the comments and answers already here - If you're having trouble connecting to it in Sql Server Management Studio - you should open Configuration Manager on the VM itself and make sure that Shared Memory and Named Pipes are enabled (open the SQL Server Network Configuration node in the tree).
For example, SQL Server Express instances are configured by default to reject the kind of remote connection that SSMS wants to open by default.
first of all check your connection string (for reference):
http://www.connectionstrings.com/
Second you need to add an exception in the guest machine firewall or completely disable it (port 1433 is for sql tcp/ip access).
this works fine for me:
SQLConn.ConnectionString = "Network Library=DBMSSOCN; Data Source=xxx.xxx.xxx.xxx,1433;
Initial Catalog=mySQLServerDBName; User ID=myUsername;Password=myPassword"
good luck

How I can connect local sql database from Oracle VM OBIEE

I am using Oracle VM for OBIEE and I want to connect my local SQL server DB
How I can do it? Are they any ODBC for vm machine?
When it comes to connect to and from VMs, the tricky part is figuring out how the IP addresses and overall networking are setup. There's nothing "special" concerning odbc connecting to a physical or virtual machine.

how to connect to another sql server database(server pc) in local area network

i m creating an application, inwhich client has to acces a database stored in a remote location connnected through a live ip. how can i connect simply with a database server placed in LAN. both using sql server 2005 express edition. please refer me or help me on this
Set in your connection string IP address of remote server.
E.g.
"Data source=192.168.0.13; Database=MyDb;User ID=my_user;password=12345"
where 192.168.0.13 is your remote server IP and MyDb is your database name.
Also, make sure to configure your SQL Server Express to allow remote connections! Those are disabled by default after installation.
Check out the SQL Server Surface Configuration tool (if I'm not mistaken) to configure these settings.

This not about programming. You have forward the port which Sql Server uses on modem.
