Inner Join Syntax review

Hi All,

I want to select the external material text from twewt table , for the corresponding material in mara , so I wrote a join statement like this -

Select singlep~ewbez  into gv_extmatdesc from (twewt as p INNER JOIN  mara as c  on C~matnr = rm_matnr)

Join is working fine and giving me output but I like to know this is the proper syntax or not
