I have table:
I want use UNPIVOT to create table, where CategoryNames rows are columns names.
So, now I can just write this as
SELECT Year, Seafood, Meat/Poultry, [...]
FROM [...] UNPIVOT(...) AS Example
but I don't want write every row manually as column name, so is any option to use
SELECT CategoryName
FROM Pods
query result to create them automatically.
For this example its only 8 row, but with bigger count this could be very helpful.

Exclude a column using SELECT * [except columnA] FROM tableA?

I was reading SQL queries and got stuck with a doubt. Is there any SQL query to exclude a single column while using select statement?
For example, I have a table which contains data about student (s_name, address, email_id, ..... many more).
I want to select all the columns except email_id.
I don't think there is a way to do it directly in a Select statement. But you can use this alternative:

Default row ordering for select query in oracle

Hi allWhile working on Oracle I came across a situation where I need to select the rows from a table in which the recently inserted row should be at the top of my selection.
But here in my table I am not using any Identity column. I know how to do the same when there is an Identity column present, but is there any way to do this without Identity column?
Unless you have a sequential ID or Timestamp or some other field you can ORDER BY, Oracle provides no guarantee of order and you should not rely on it.

In SQL you can do something like this:
