Select record from database table

Question

how to select a record from data-base table for current month in module-pool, i.e if current month is august then records selected should between 1/08/10 to 31/08/10.
And, i also want to select records for last month i.e if current month is august then records selected should be between 1/07/10 to 31/07/10.
And one thing more, it should work for every scenario. Like for months are changing then it should work according to that.
Example: If month changes to October then current month ll be October and last month ll become September.
Plz help me out.

Hi Nishant,
You can use the option <b>ORDER BY </b> in your SELECT clause.
This is the SAP Documentation for <b>ORDER BY </b> option.
<i>Variant 1</i>
<b>...ORDER BY PRIMARY KEY</b>
<b>Effect</b>
Sorts the selected lines in ascending order by the primary key of the database table. This variant is only permitted for SELECT * ....
<i>Notes</i>
Since views do not have a primary key, specifying ORDER BY PRIMARY KEY only makes sense with database tables. If, however, you do specify ORDER BY PRIMARY KEY with a view, all fields of the view are sorted in ascending order.
<i>Variant 2</i>
<b>ORDER BY f1 ... fn</b>
<i>Effect</i>
Sorts the selected records in ascending order by the specified column references f1 ... fn. If a list is also specified in the SELECT clause, the column references f1, ..., fn must appear in this list.
By supplementing the statement with DESCENDING, you can sort in descending order using any of the fields f1, ..., fn.
The default sort sequence is ascending order, but you can make this explicit by adding the addition ASCENDING.
Consider this code this will select the latest 10 records form DB table(Note can use <b>Variant 2</b> for DB tables also.
REPORT zarun_1.
DATA : it_mara TYPE STANDARD TABLE OF mara WITH HEADER LINE.
START-OF-SELECTION.
  SELECT * FROM mara
            INTO TABLE it_mara
            <b>UP TO 10 ROWS                "No of rows you need(give 1 here)
           ORDER BY matnr DESCENDING.    "Specify the Key Fields here.</b>
  LOOP AT it_mara.
    WRITE : / it_mara-matnr,
              it_mara-mtart.
  ENDLOOP.
