The SQL Server ASCII function takes in a character and returns the ASCII value. If you pass in a unicode character or rune, the function will return the unicode value.
The basic syntax of a ASCII is as follows:
For this, we will be using docker. This is recommended for more than just using SQL Server. To find how to install docker go here: https://docs.docker.com/engine/install/
Now create a file called
docker-compose.yml and add the following.
version: "3.9" services: db: image: "mcr.microsoft.com/mssql/server" ports: - 1433:1433 environment: SA_PASSWORD: "Your_password123" ACCEPT_EULA: "Y"
Open a terminal and go to the folder the file is located. Then run the following.

In the basic example, we pass in an ascii character and the function will return the ascii code corresponding to that character.
You can see a reference of ascii characters here: https://web.archive.org/web/20220519180720/https://www.ascii-code.com/
If we pass a string instead, postgresql will only return the ascii value of the first character.
This is the same value if we only pass the 't' character.
And finally, we can pass a unicode character to get a unicode value.
