Question

I have this query:

Select * 
From Player_Chkin_Cs

That spits out the result:

Player_ID     CS_ID   CS_LISTING_ID  CS_COMP_NAME   PT_ADD  CREATE_DTIME   UUID
 179364        300      60132          Wilshire       3      22-DEC-10     (null)
 179364        320      68968          Wilshire       30     28-JAN-10     (null)
 132489        200      55168          Wilshire       13     03-Jan-10     (null)
 132489        900      65478          Wilshire       23     15-Feb-10     (null)

I want to create a query that returns the player_ids of only players who have create_dtimes that fall in both the ranges of 01-Dec-10 to 31-Dec-10 AND 01-Jan-10 to 31-Jan-10.(aka only Player_ID 179364 would show up in the results of this example)

Please let me know if you have any suggestions!

Answer 1

One option would be

SELECT player_id,
       COUNT(DISTINCT trunc(create_dtime, 'MM')) num_months
  FROM player_chkin_cs
 WHERE trunc(create_dtime,'MM') IN (date '2010-12-01', date '2010-01-01')
 GROUP BY player_id
HAVING COUNT(DISTINCT trunc(create_dtime, 'MM')) = 2
