Mar 14, 2018 SQL Server with.NET Core and EntityFramework on Mac By Stefan on I completely updated this article on Medium, implementing a full example on GitHub and using just Visual Studio Code. Introduction In this chapter, we will work with Visual Studio to connect to SQL Databases in Azure. The first part of this chapter will be to create a Database in the Azure Portal and the second part will be to connect in Visual Studio and create some Database Objects. I am using Visual Studio on Mac (release edition) and I want to connect to a SQL Server. I am aware that probably the most recommended way would be to create a web service and I understand why. However, I am so unsuccessful in doing it any other way.
To make this possible, I'm using ASP .NET Core with Entity Framework Core. For the database, I use a Docker image with Sql Server for Linux that can run on Mac.
So this is how it goes…
To setup a SQL Server with Docker, you just have to follow a few simple steps:
Download and install Docker for Mac.
docker pull mcr.microsoft.com/mssql/server:2017-latest-ubuntu
docker run -e ‘ACCEPT_EULA=Y' -e ‘MSSQL_SA_PASSWORD=1StrongPassword!' -p 1401:1433 –name sql1 -d microsoft/mssql-server-linux:2017-latest
sudo docker ps -a
I recommend SQL Operations Studio:
For a deeper understandment of Docker for this case, I recommend you this page.
For EntityFramework Core to work, you need an executable project in your solution. So for this demo, we just go with a simple .NET Core Console application. In VisualStudio on Mac, just go to
File – New Solution – .NET Core – App – Console Application
Then you add a simple class containing two properties Id and Name.
That's it for the example project. Now we'll look how we create a database with a ‘Person' table with EntityFramework Core.
For EF Core to work, you need to add just two packages. They contain all the dependencies for the other packages, and will pull them in.
Actually this is the simple way of going, when you're keeping everything inside one project. If you're splitting your code in a data library (containing the DbContext), you ‘just' need the Designer package in the executable, and the other package in the Data project. But let's not worry about that right now.
This is the main entry point for EntityFramework Core in your project. Create a class PersonContext that inherits from DbContext, and override the method OnConfiguring to configure the connection string to the database. Also, you'll need to define the DbSets for each class you want to store in the database as a table.
Of course there's better ways to configure this (through the application config file), but I want to keep it as simple as possible here.
Now comes the tricky part – using EntityFramework Core to generate migrations and create/update the database automatically. For this, we have the Package Manager commands in VisualStudio on Windows. But what about Mac?
Now you can create your first migration using the command:
dotnet ef migrations add initial
(You can choose another name over ‘initial' of course)
You can see your first migration in the project, after you refresh:
Now there is just one last step left – to execute the migration:
dotnet ef database update
And voilá! The new database and table appear in the database!
Now you can start using all the EntityFramework Core features in your code. If you want to learn more about that, I recommend you this Pluralsight course.
So long…
Hello Programmers, here is the article to connect SQL server with visual studio. Microsoft visual studio has nice facility where you can easily connect any database with visual studio. this article i am using SQL Server 2019 and Visual Studio 2019.
Let's see the all important steps to connect VS with ssms.
1.Click 'Tools' Tab and next Click 'Connect to Database'.See below image.
2.Choose 'Microsoft SQL Server' from Data source and click 'Continue' button. see below image.
3.Give Microsoft SQL Server name,you can select Windows Authentication or you can give SQL Server Authentication.Enter User name and Password. Select or enter a database name from drop down box. Click 'Test Connection' button. if connection succeeded then click OK. Follow below image.
4.After Clicking OK button,you can see SQL Server successfully connected with Visual Studio.you can see in below image. now you can use the connection in Any Code.
Happy Connection… Thanks.
Here I'll show you how to get SQL Server up and running on your Mac in less than half an hour. And the best part is, you'll have SQL Server running locally without needing any virtualization software.
Prior to SQL Server 2017, if you wanted to run SQL Server on your Mac, you first had to create a virtual machine (using VirtualBox, Parallels Desktop, VMware Fusion, or Bootcamp), then install Windows onto that VM, then finally SQL Server. This is still a valid option depending on your requirements (here's how to install SQL Server on a Mac with VirtualBox if you'd like to try that method).
Starting with SQL Server 2017, you can now install SQL Server directly on to a Linux machine. And because macOS is Unix based (and Linux is Unix based), you can run SQL Server for Linux on your Mac. The way to do this is to run SQL Server on Docker.
So let's go ahead and install Docker. Then we'll download and install SQL Server.
Download the (free) Docker Community Edition for Mac (unless you've already got it installed on your system). This will enable you to run SQL Server from within a Docker container.
To download, visit the Docker CE for Mac download page and click Get Docker.
To install, double-click on the .dmg file and then drag the Docker.app icon to your Application folder.
Docker is a platform that enables software to run in its own isolated environment. SQL Server (from 2017) can be run on Docker in its own isolated container. Once Docker is installed, you simply download — or 'pull' — the SQL Server on Linux Docker Image to your Mac, then run it as a Docker container. This container is an isolated environment that contains everything SQL Server needs to run.
Launch Docker the same way you'd launch any other application (eg, via the Applications folder, the Launchpad, etc).
When you open Docker, you might be prompted for your password so that Docker can install its networking components and links to the Docker apps. Go ahead and provide your password, as Docker needs this to run.
By default, Docker will have 2GB of memory allocated to it. SQL Server needs at least 3.25GB. To be safe, increase it to 4GB if you can.
To do this:
Now that Docker is installed and its memory has been increased, we can download and install SQL Server for Linux.
Open a Terminal window and run the following command.
This downloads the latest SQL Server 2019 for Linux Docker image to your computer.
You can also check for the latest container version on the Docker website if you wish. Native instruments vst mac.
Update: When I first wrote this article, I used the following image:
Which downloaded SQL Server 2017. Therefore, the examples below reflect that version.
Run the following command to launch an instance of the Docker image you just downloaded:
But of course, use your own name and password. Also, if you downloaded a different Docker image, replace microsoft/mssql-server-linux with the one you downloaded.
Here's an explanation of the parameters:
-d | This optional parameter launches the Docker container in daemon mode. This means that it runs in the background and doesn't need its own Terminal window open. You can omit this parameter to have the container run in its own Terminal window. |
--name sql_server_demo | Another optional parameter. This parameter allows you to name the container. This can be handy when stopping and starting your container from the Terminal. |
-e 'ACCEPT_EULA=Y' | The Y shows that you agree with the EULA (End User Licence Agreement). This is required in order to have SQL Server for Linux run on your Mac. |
-e 'SA_PASSWORD=reallyStrongPwd123' | Required parameter that sets the sa database password. |
-p 1433:1433 | This maps the local port 1433 to port 1433 on the container. This is the default TCP port that SQL Server uses to listen for connections. |
microsoft/mssql-server-linux | This tells Docker which image to use. If you downloaded a different one, use it instead. |
If you get the following error at this step, try again, but with a stronger password.
I received this error when using reallyStrongPwd as the password (but of course, it's not a really strong password!). I was able to overcome this by adding some numbers to the end. However, if it wasn't just a demo I'd definitely make it stronger than a few dictionary words and numbers.
You can type the following command to check that the Docker container is running. What are all the mac os versions.
If it's up and running, it should return something like this:
Run the following command to install the sql-cli command line tool. This tool allows you to run queries and other commands against your SQL Server instance.
This assumes you have NodeJs installed. If you don't, download it from Nodejs.org first. Installing NodeJs will automatically install npm which is what we use in this command to install sql-cli.
If you get an error, and part of it reads something like Please try running this command again as root/Administrator
, try again, but this time prepend sudo to your command:
Now that sql-cli is installed, we can start working with SQL Server via the Terminal window on our Mac.
Connect to SQL Server using the mssql command, followed by the username and password parameters.
You should see something like this:
This means you've successfully connected to your instance of SQL Server.
Run a quick test to check that SQL Server is up and running and you can query it.
For example, you can run the following command to see which version of SQL Server your running:
If it's running, you should see something like this (but of course, this will depend on which version you're running):
If you see a message like this, congratulations — SQL Server is now up and running on your Mac!
Azure Data Studio (formerly SQL Operations Studio) is a free GUI management tool that you can use to manage SQL Server on your Mac. You can use it to create and manage databases, write queries, backup and restore databases, and more.
Azure Data Studio is available on Windows, Mac and Linux.
Here are some articles/tutorials I've written for Azure Data Studio:
Another SQL Server GUI tool that you can use on your Mac (and Windows/Linux/Solaris) is DBeaver.
DBeaver is a free, open source database management tool that can be used on most database management systems (such as MySQL, PostgreSQL, MariaDB, SQLite, Oracle, DB2, SQL Server, Sybase, Microsoft Access, Teradata, Firebird, Derby, and more).
I wrote a little introduction to DBeaver, or you can go straight to the DBeaver download page and try it out with your new SQL Server installation. Vlc media player mac os x 10 4.
SQL Server for Linux does have some limitations when compared to the Windows editions (although this could change over time). The Linux release doesn't include many of the extra services that are available in the Windows release, such as Analysis Services, Reporting Services, etc. Here's a list of what's available and what's not on SQL Server 2017 for Linux and here's Microsoft's list of Editions and supported features of SQL Server 2019 on Linux.
Another limitation is that SQL Server Management Studio is not available on Mac or Linux. SSMS a full-blown GUI management for SQL Server, and it provides many more features than Azure Data Studio and DBeaver (at least at the time of writing). You can still use SSMS on a Windows machine to connect to SQL Server on a Linux or Mac machine, but you just can't install it locally on the Linux or Mac machine.
If you need any of the features not supported in SQL Server for Linux, you'll need SQL Server for Windows. However, you can still run SQL Server for Windows on your Mac by using virtualization software. Here's how to install SQL Server for Windows on a Mac using VirtualBox.
