st: stata command for joint significant in large sample test

["Joanne Marshall" <jmarshall1982@hotmail.co.uk>]

Dear fellow,

if i was to test the joint significance test using a large sample test in 
stata for educ, wage and married

which of the following command do I use in Stata?

test educ wage married

or

test educ+wage+married=0

they generate different results, actually opposite results, one being 
significant and one insignificant. Note I will want to use a large sample 
test here.

Thank you very much, any comments are appreciated!

Cheers
Jo
