sql server - Declaring Temp Table -

-

I am reviewing and reviewing stored procedures, I see this announcement in one of the processes I think it is trying to make a floating table named @uzovi_nummers, I'm trying to figure out what it is "uzovi_nummer_n_4" is it a custom datatype? 

  DECLARE @uzovi_nummers TABLE (uzovi_nummer uzovi_nummer_n_4, jar INT)

This is a table variable with a hash near a floating table which is in front of #temptable . Any one of the variables written in the query with a single @ A

Also, there is a reasonable amount of difference between the floating table and a table variable, to understand the difference There will be good reading for
