Обсуждение: How do I do this in plpgsql ?

Hi !

Is there a way to use plpgsql copy type to get an array of a certain type ?

For example if I have a type sample%TYPE
How can I declare a variable that is an array of sample%TYPE
I can't get it to work, is there a way to do it ?

Best Regards

I don't think it's possible.  Can you give some more detail on what
you are trying to do?

No, it's not supported :(

Well I had the hope to only define the type used for this column in one place.
Now I needed an array of the same type do some procedural calculations.
I figured that the best way was to get an array of this type by copying the type used to fill the array.

Anyway I will declare the array the usual way then.

Thank you Merlin and Pavel for your quick answers

Nope, there is no way. However, you can create a userdefined type and can also use array of that
