SQL Server: Declaring variable type based on a column type

Question

In Oracle's PL-SQL, you can declare a variable and define its type based on a table column:

declare var1 table.column%TYPE;

Is it possible to do something similar in MS SQL Server?

I searched but could not find a duplicate for this question. If there is one, please let me know and I'll refer to it and delete this.

Answer 1

No you can't do this. The closest equivalent is User-Defined Data Types. This will give you a layer of abstraction that may help, but it is not the same as deriving a type from a column.

Answer 2

It may skirt the real issue, but you can "cheat" a little bit by

Select *
INTO #tmp
From MyTable
Where 1 = 0

Will automatically create a temp table with all columns with correct data types.
