Inner join taking more time

Question

Hi Experts,
I have joined two table prps and proj by inner join . But it is taking more time.
pls advice.
the code is:
  select prps~posid                                        
         prps~post1
         prps~objnr
         prps~pbukr
         prps~prctr
         prps~erdat
         prps~zz_can
         into table  itab_prps_all
         from proJ inner join prps
         on projpspnr = prpspsphi
              where prps~posid IN   sel_wbs
              AND   prps~pbukr IN   sel_comp
              AND   prps~prctr IN   sel_prct
              AND   prps~erdat IN   sel_date
              and   proj~pprof NE wa_pprof.
thanks in advance,

Answer 1

hi,
plz use  FOR ALL ENTRIES IN  , it will increase performance of code
example:
Exporting all flight data for a specified departure city. The relevant airlines and flight numbers are first put in an internal table entry_tab, which is evaluated in the WHERE condition of the subsquent SELECT statement.
PARAMETERS p_city TYPE spfli-cityfrom.
TYPES: BEGIN OF entry_tab_type,
         carrid TYPE spfli-carrid,
         connid TYPE spfli-connid,
       END OF entry_tab_type.
DATA: entry_tab   TYPE TABLE OF entry_tab_type,
      sflight_tab TYPE SORTED TABLE OF sflight
                       WITH UNIQUE KEY carrid connid fldate.
SELECT carrid connid
       FROM spfli
       INTO CORRESPONDING FIELDS OF TABLE entry_tab
       WHERE cityfrom = p_city.
SELECT carrid connid fldate
       FROM sflight
       INTO CORRESPONDING FIELDS OF TABLE sflight_tab
       FOR ALL ENTRIES IN entry_tab
       WHERE carrid = entry_tab-carrid AND
             connid = entry_tab-connid.
thanks and regards
