Hi.....
Check this... Here Iam joining MARA and MAKT tables.....
data: begin of itab occurs 0,
      matnr like mara-matnr,             <----like this you can select no.of fields from MARA
      spras like makt-spras,             <----like this you declare ur internal table with no.of fields of MAKT table
      end of itab.    
parameters: p_matnr like mara-matnr.      <------ Later according to this material number you can display details
select p~matnr q~spras          <----with p~ you can declare no.of from MARA, but those should me mention in above ITAB , also MAKT with q~
         from
         mara as p                      <---- p is for first table fileds
         inner join                         <----- key word
         makt as q                          <----- q is for second table fields
          on p~matnr = q~matnr       <----this is for link
          into corresponding fields of table itab
          where p~matnr = p_matnr.       <------checking where condition with parameter
loop at itab.
write:/ itab-matnr,            <--------here you can display the fields which you defined in ITAB
          itab-spras.
endloop.
Also check this query....
Here you can display all the details of that tables...
data: begin of itab occurs 0,
      matnr like mara-matnr,
      spras like makt-spras,
      end of itab.
data: p_matnr like mara-matnr.
select-options: g_matnr for p_matnr.              <------First change
select p~matnr q~spras from mara as p inner join makt as q
          on p~matnr = q~matnr
          into corresponding fields of table itab
          where p~matnr in g_matnr.                   <----second change
loop at itab.
write:/ itab-matnr,
          itab-spras.
endloop.
Also check this code and get an idea about for all entries method and joining of more than two tables...
data: begin of itab occurs 0,
      matnr like mara-matnr,
      spras like makt-spras,
      end of itab.
data: begin of jtab occurs 0,
      matnr like marc-matnr,
      werks like marc-werks,
      end of jtab.
data: begin of t_out occurs 0,
      matnr like mara-matnr,
      spras like makt-spras,
      werks like marc-werks,
      end of t_out.
data: p_matnr like mara-matnr.
select-options: g_matnr for p_matnr.
select p~matnr q~spras from mara as p inner join makt as q
          on p~matnr = q~matnr
          into corresponding fields of table itab
          where p~matnr in g_matnr.
if itab[] is not initial.
  select * from marc into corresponding fields of table jtab
            for all entries in itab
            where matnr = itab-matnr.
endif.
loop at itab.
  t_out-matnr = itab-matnr.
  t_out-spras = itab-spras.
  read table jtab with key matnr = itab-matnr.
  if sy-subrc = 0.
    t_out-werks = jtab-werks.
  endif.
  append t_out.
  clear t_out.
endloop.
loop at t_out.
  write:/ t_out-matnr,
          t_out-spras,
          t_out-werks.
endloop.
All the best!!
