SQuiL
This is the source repo of the SQuiL prototype - a proof-of-concept for a generic SQL UI.
For a quick look at the thing, use the public demo hosting:
If you have a SQL Server database with proper foreign key constraints between the tables, you may want to check out how it looks in SQuiL. It's easy to install with the docker image, see the section below.
If you are interested in the vision behind this prototype, I've written something about that and myself on a dedicated site:
Install and use the docker image
First, you need Docker installed. If you're unfamiliar with that, just go to Docker and install Docker Desktop for your operating system. It comes with a user interface to start and stop created containers, but the container creation itself should be done in a terminal.
(If you don't use Docker for anything else you may want to go to its settings and disable the automatic startup on login. Docker obviously consumes significant resources.)
Now install or update the SQuiL image with
docker pull squiltech/squil
This pulls the image into a user-wide storage that you can also browse in the Docker UI.
Before you then create a container instance from this image, first create an environment variables file defining your database connections. The file's name and location doesn't matter, and the contents should look like this:
Connections__0__Name=AdventureWorksLT2017
Connections__0__LongName=AdventureWorks 2017 Light
Connections__0__ConnectionString=Server=host.docker.internal;Initial Catalog=AdventureWorksLT2017;User ID=squil;Password=qwerty;TrustServerCertificate=False;Connection Timeout=30;
Connections__0__Description=Microsoft's AdventureWorks database is the official example database for Microsoft SQL Server.
Replace the values accordingly.
The format comes from the way ASP.NET expects list settings in environment variables by default. You can add multiple connections by replacing the zero with increasing integers.
Then, you can create and run a container:
docker run -d -p 8080:80 --env-file <environment-file> --name squil squiltech/squil
This will create and run a container named squil that can be started and stopped and uses the connections defined in the environment file (which won't be used anymore after that). When running, it listens to port 8080, so the app will be at http://localhost:8080.
Connect to a server on your local machine
Docker containers run technically on a different machine (from the OS perspective), so neither Windows authentication nor connecting via pipes (the default) works.
For SQuiL running in docker to connect to your local SQL Server instance, you
- need to enable TCP in your SQL Server,
- must refer to host.docker.internal (rather than localhost) as the server hostname in your connection strings and
- must use SQL Server authentication (rather than Windows authentication) and thus likely also create a SQL Server login.
The setting to enable TCP is in the SQL Server Connection Manager, which is a bit hidden. See this blog post to find it and this Stack Overflow answer to locate the setting once you found the manager.
Since Windows authentication can't be used here either, you need to create a login that uses SQL Server authentication with username and password. This can be done with SQL Server Management Studio by right-clicking on the connection/Security/Logins node in the object tree and selecting New Login. The relevant tabs here are General and User Mapping
Give that login a name, check SQL Server authentication and set a password. Then, under User Mapping, give the login a user mapping to the relevant databases with the db_datareader role checked for each such database in the list of roles below. You can then use that user/password combination with the server name host.docker.internal in your connection strings.
