Generating Plots Automatically From PowerShell and SQL Server Using Gnuplot

  • Article

If you are using PowerShell and maybe also SQL Server, it pays to use a command-line plotting tool such as Gnuplot to do all the hard work. It turns out to be handy for a range of data jobs, turning PowerShell into a handy data science tool.

PowerShell Time Saver: Automatic Defaults

  • Article

Because PowerShell needs to be usable as an immediate scripting language by IT professionals who type in commands at a console, there have to be language devices such as aliases that can make for terseness when appropriate. There are several ways of cutting down the verbiage in a script, and being able to specify default values via $PSDefaultParameterValues is one of the more generally useful ones. Michael Sorens explains how it can save you time in your daily work.

Lists With, or Without, Ranges in both T-SQL and PowerShell

  • Article

Whether you are working in a procedural language like PowerShell or in T-SQL, there is something slightly bothersome about having to deal with parameters that are lists, or worse with ranges amongst the values. In fact, once you have a way of dealing with them, they can be convenient, especially when bridging the gulf between application and the database. Phil Factor shows how to deal with them.

Question of the Day

Changing the Schema

I set up a few users on my SQL Server 2022 instance.

CREATE LOGIN User1 WITH PASSWORD = 'Demo12#1'
CREATE USER User1 FOR LOGIN User1
GO
CREATE LOGIN User2 WITH PASSWORD = 'Demo12#2'
CREATE USER User2 FOR LOGIN User2
GO
CREATE LOGIN User3 WITH PASSWORD = 'Demo12#3'
CREATE USER User3 FOR LOGIN User3
GO
I then created a schema that one of them owned. Under this schema, I added a table with some data.
CREATE SCHEMA MySchema AUTHORIZATION User1
GO
CREATE TABLE Myschema.MyTable(myid INT)
GO
INSERT MySchema.MyTable
(
    myid
)
VALUES
(1), (2), (3)
GO
SELECT * FROM MySchema.MyTable
GO
I granted rights and verified that User2 could access this table.
GRANT SELECT ON Myschema.MyTable TO User2
GO
SETUSER 'USER2'
GO
SELECT * FROM MySchema.MyTable
GO
This worked. Now, I move this schema to a new user.
ALTER AUTHORIZATION ON SCHEMA::Myschema TO User3;
GO
What happens with this code?
SETUSER 'USER2'
GO
SELECT * FROM MySchema.MyTable
GO
