QUESTION
How can I see the SQL code behind DMVs in SQL Server?
DMVs are providing useful stats, but what are the tables involved in it which are fetching data?
Ex:
...ANSWER
Answered 2021-Mar-27 at 14:46The easiest way I know to get what you're asking is to use Redgate SQL Prompt
It will give you the definitions of all the system views, although it won't really do you much good as they make use of internal server objects that are not available to you.
However as an example, the DMV you cite above is defined as

I have an issue when I try to update the type of user (Base or Licensed) with Zoom API. I need to give licenses automatically to a group of users. It works only for the first user, and when I try to update the second one, I get this error:

An HTTPConnection instance represents one transaction with an HTTP server.

QUESTION
I am a beginner here and I thought everything was going great until I received this error message: syntax error at prog.pl line 24, near "SignificanceofPlate" Execution of prog.pl aborted due to compilation errors. Can someone please help and explain what is wrong with line 24? If there is something wrong with line 24, shouldn't there be something wrong with all the lines containing "SignificanceofPlate"? They're all the same. Line 24 is the first "SignificanceofPlate" under Alaska. I was thinking it was too long so I shortened the name, but I still ran across the same problem.

QUESTION
I want to use flex to transform a string based on simple rules. I have rules like the first character stays the same and the second and third characters might change. Like if the second character was a letter, it becomes the number listed in the rules below. If the third is a digit, it becomes a certain letter.
...ANSWER
Answered 2020-Oct-20 at 22:11You switch start condition by using the BEGIN action. Flex never automatically changes start condition, so you when you need to return to the initial start condition (called INITIAL), you have to do so explicitly (BEGIN(INITIAL)).
You need to declare start condition names in the (f)lex prologue, usually with the %x command. (%s is also possible but with different semantics. See the Flex manual for details.)
You indicate that a start condition applies to a rule by starting the rule with a start condition name in angle brackets. You can put more than one start condition inside the angle brackets; separate them with commas and don't use spaces. Don't put a space after the angle brackets either; they are part of the pattern and (f)lex patterns cannot include unquoted space characters.
BEGIN is a macro and it does not require parentheses around the start condition name, but I suggest always using them anyway, so you don't have to worry about what the macro expands to. Start condition names are small integers (either enum constants or preprocessor macros) but nothing guarantees their value, so don't make assumptions.
That's about it. So you could implement your astro numerological codifier with:
QUESTION
I have a SP that runs at night and sometimes it does not finish. The tool I automate the runs with has an option about that can kill the job after some time if it does not finish, i.e. it kills the job e.g. after one hour.
Anyway I think the reason it sometimes does not finish in the maximum allotted time is because it is being blocked by another session ID. How can I query the DMV's for the text of the query and find out exactly what is in the blocking session.
I have this query and I know the blocking session ID and my session ID.

I am new to Python and fairly new to programming in general. I'm trying to work out a script that uses BeautifulSoup to parse https://www.state.nj.us/mvc/ for any text that's red. The table I'm looking at is relatively simple HTML:

To only get text that's red you can use the CSS selector soup.select('font[color="red"]') as @Mr. Polywhirl mentioned:
QUESTION
I'm working with an externally developed XSD that I need to conform to, where a field Engine can be one of two types: Electric or Combustion. Both are derived from super-class Engine.
There are multiple ways to have the XmlSerializer in C# handle this, but all are seemingly associated with the same side-effect: default serialization naming conventions are tossed out the window when using a custom serializer-apporach. I want to mimic the default behaviour for the remaining fields of the class Vehicle.
Consider the following:
...ANSWER
Answered 2020-Sep-15 at 20:58Try using a specific constructor for XmlSerializer that accepts an array of 'other types' to handle your derived classes, rather than implementing IXmlSerializable and doing the serialization manually. The serializer will now handle your derived classes, but also pick up your other attributes (such as XmlElement) the way you want:
QUESTION
I've read a few articles like this one about a license plate value of NULL (about Droogie from DEF CON 27), including part of chapter three Little Data in the book Humble Pi by Matt Parker (talking about Steve Null), where storing a string value of "NULL" in a database matches NULL values.
With databases I've used (at least AFAIK), "NULL" isn't the same as a NULL value. The state of a field being NULL is stored separately from the value.
So SQL like
...ANSWER
Answered 2020-Aug-25 at 17:37It's a design flaw. "NULL" is a string and you shouldn't have to use a string to represent Nothing. So in 1 case, you're looking for a populated value of exactly "NULL" where with IS NULL there actually is nothing there.
