You have to define variables.

DEFINE @NomeVariavel_1 as INT
DEFINE @NomeVariavel_2 as VARCHAR(100)
DEFINE @NomeVariavel_3 as DATETIME
DEFINE @NomeVariavel_4 as VARCHAR(100)

Set how many variables you need to pass in Sproc .

Then in% w / o you want to get the results to pass as a parameter in another Sproc , you do:

SELECT
    @NomeVariavel_1 = Campo_1,
    @NomeVariavel_2 = Campo_2,
    @NomeVariavel_3 = Campo_3,
    @NomeVariavel_4 = Campo_4,
FROM
    Tabela

When you do this, you can call Sproc with the command SELECT , setting the variables as parameters.

EXEC SP_NOME_STORED_PROCEDURE @NomeVariavel_1, @NomeVariavel_2, @NomeVariavel_3, @NomeVariavel_4

Now

Why do you need two Sproc ?

Can not do what you want in one?

With variables this is possible.
