Recent Code Inspector Enhancements 4.3DATA: lt_monsters TYPE STANDARD TABLE OF ztvc_monsters,lt_selections TYPE RANGE OF zde_monster_number.IF lt_selections[] IS NOT INITIAL.SELECT *FROM ztvc_monstersINTO CORRESPONDING FIELDS OF TABLE lt_monstersFOR ALL ENTRIES IN lt_selectionsWHERE monster_number = lt_selections-low.ENDIF.Listing 4.3 Check for Empty TablesIf you rerun the Code Inspector, then you’ll find that the error message has vanishedlike a phantom into the night.4.3.2 SELECT * Analysis (14/9/2)SELECT * analysis is a tool that identifies where you have used SELECT * in yourcode so that you can then make sure th at you are only using it when absolutelynecessary. The reason you want to be careful with SELECT * is that it brings backevery single column from the database table being accessed—and this breaks thegolden rule of minimizing the amount of data being transferred from the databaseto the application server.In the example, a SELECT * has just been performed on the monsters table to bringback every single column. Now, write some code as shown in Listing 4.4 to outputthe desired result to the user.LOOP AT lt_monsters INTO ls_monsters.WRITE:/ ls_monsters-monster_number,ls_monsters-hat_size.ENDLOOP.Listing 4.4 Ouputting the ResultEven though you’re only interested in two columns of the table, it turns out thatyou’ve retrieved every single column from the database. This is naughty, becauseit puts undue strain on the system. You should be ashamed of yourself.Fortunately, you can use the Code Inspector default variant to fix this. Figure 4.18shows the Search Problematic SELECT * Statements option; all you have to dois make sure this option is checked in your system.195
