join two tables

I have two tables with some data in both of them .Im trying to join those tables for expected result  but I didn't get the correct result.Please check below data in both tables

ScheduleTasks
ID       Projects        CType  Empname sstatus     sscomments
1	All Projects	EF&I	Andy,	 schedule  test in schedule
2	Winsphear/Wylie	Phase3+	Jim,
3	All Projects	EF&I	Ray,    process      test in Process
4	All Projects	EF&I	Tom      Complete     test in Comeplte
5	All Projects	Phase3+	Tom,
6	All Projects	Phase3+	Jim,


ST_Phase3

PID    ST_ID    r1       sratdate       enddate             rstatus      rscomments        
1	1	NULL	NULL	NULL	Select 
2	2	Phase3+	 2014-04-02 	2014-04-04         schedule     test in schedule  
3	3	NULL	NULL	NULL	Select 
4	4	NULL	NULL	NULL	Select
5	5	Phase3+	2014-05-13 	2014-05-14            test          test 
6	6	Phase3+	2014-05-07 	2014-05-23          test           test

from the above tables  I want display only EFI from firsttable  and Phase3+ from secondTable

Select * from ScheduleTasks a full Outer Join ST_Phase3 b
On a.CType = b.CType
And a.ID = b.PID

I tried with full outer join but it shows only  scheduletasks tbale  data

	[ID] [int] IDENTITY(1,1) NOT NULL,
