I'm having some issues getting the correct outcome for this query. When I enter this code :

 SQL> select dr_drvname, ic_cabnum, ic_incitype
  2  from (driver JOIN shift ON sh_drvnum = dr_drvnum) JOIN incident ON ic_wkdate = sh_wkdate
  3  where ic_wkdate = '15-NOV-2007'
  4  order by dr_drvnum;

I get the correct selections but I am getting multiples for each incident type.

DR_DRVNAME IC_ IC_INCITYPE

Why is this happening and what do I need to change?

Thanks

The output I should be getting based on my table should have only 6 incidents with no repeating information.

HOLY CRAP! I finally got it!!!! I probably should have posted tables as it would have probably been helpful. Code that pulled the correct output was

SQL> select dr_drvname, ic_cabnum, ic_incitype
  2  from (driver join shift on dr_drvnum = sh_drvnum)
  3  join incident on ic_wkdate = sh_wkdate and ic_wkshift = sh_wkshift and ic_cabnum = sh_cabnum
  4  where ic_wkdate = '15-NOV-2007';

For future reference when I am joining tables, do I need to show all fields that are the same from joining tables? Like with the join on incident and shift.

Thanks for making me work that out on my own. Pretty rewarding feeling that I figured it out myself.
This is a huge project for school so I'll probably be posting some more questions soon. Some of these queries are ridiculous and our book does a poor job in covering what is being asked in a majority of the queries.
