MSSQL server with Docker

https://database.guide/how-to-install-sql-server-on-a-mac/

get docker container

sudo docker pull microsoft/mssql-server-linux:latest

create docker container
password needs
Uppercase letters, Lowercase letters, Base 10 digits, and Symbols..
docker run -e'ACCEPT_EULA=Y' -e'MSSQL_SA_PASSWORD=YourPassword123!' -p 1433:1433 --name sqlserver -d microsoft/mssql-server-linux

start docker container
docker exec -it sqlserver bash

run as SA
/opt/mssql-tools/bin/sqlcmd -U SA

view password (!)
echo $MSSQL_SA_PASSWORD

change password:
docker exec -it sqlserver2 /opt/mssql-tools/bin/sqlcmd -U SA'Root123!' -Q'ALTER LOGIN SA WITH PASSWORD="YourPassword123!"'

download
mssql datastudio

create and save data in volume

docker run -e'ACCEPT_EULA=Y' -e'MSSQL_SA_PASSWORD=YourPassword123!' -p 1433:1433 --name sqlserver2 -v sqlservervolume:/var/opt/mssql -d microsoft/mssql-server-linux

to see volumes
docker volume ls

backup external to local desktop...
docker cp newsqlserver:/var/opt/mssql ~/Desktop

copy into container
docker cp ~/Desktop/filetocopy.ext newsqlserver:/

backup from within the mssql in new backup folder
/opt/mssql-tools/bin/sqlcmd -U SA //get in db
1> BACKUP DATABASE Products TO DISK ='/var/opt/mssql/backup/Products.bak'
2> GO

exit
copy it to desired location...

code first approach:
dotnet ef migrations add InitialMigration
dotnet ef database update

    func randomColor(seed: String) -> UIColor
    {
       
        var total: Int = 0
        for u in seed.unicodeScalars {
            total += Int(UInt32(u))
        }
       
        srand48(total * 200)
        let r = CGFloat(drand48())
        srand48(total)
        let g = CGFloat(drand48())
        srand48(total / 200)
        let b = CGFloat(drand48())
       
        return UIColor(red: r, green: g, blue: b, alpha: 1)
    }
}

let str = "abcd"
let a = UIColor().randomColor(seed: str)
is the same with
let b = UIColor().randomColor(seed: str)
is the same with
let c = UIColor().randomColor(seed: str)

Main and Background Queues

let main = DispatchQueue.main
let background = DispatchQueue.global()
let helper = DispatchQueue(label: "another_thread")
Working with async and sync threads!

background.async { //async tasks here }
background.sync { //sync tasks here }
