Sql selecting specific dates?

WE absolutely suck in SQL and difficult to know how to achieve this.
I would like a statement that could select many from our “MEMBER” table the place that the members joined inside same month.

I understand it becomes something like

FIND *
OUT OF MEMBER
EXACTLY WHERE MEMBER_SINCE =

My prepare was in order to just modify the thirty day period by number to go back the effects.
Might anyone assistance me conclude this statement
Please attempt to keep the item simple.
Thanks

SELECT *
OUT OF MEMBER
EXACTLY WHERE month(MEMBER_SINCE) = 1

it is going to select many columns via member table where thirty day period is JAN

SELECT row_name
OUT OF Table_name
EXACTLY WHERE row_name=’row1′;

That should select this row1 from your row_name VIA table_name.
