i want start_dt column having values 18-jun-15, 19-jun-15 , 20-jun-15

desired output

prop_id blk_id  arrival_dt  departure_dt    num_stay    start_dt    day_num star_num    booking_num create_dt   room_type   revenue room_num    adults     353     3669281  18-jun-15  21-jun-15          1        18-jun-15   1        579071315  21803       13-jul-15   w             314   2009          1     353     3669281  18-jun-15  21-jun-15          1        19-jun-15   2        579071315  21803       13-jul-15   w             314   2009          1     353     3669281  18-jun-15  21-jun-15          1        20-jun-15   3        579071315  21803       13-jul-15   w             314   2009          1

the query i'm using complex , using multiple tables fetch data , confuse more, need way given arrival_dt , departure_dt, should generate sequence of dates within arrival_dt , departure_dt range can integrate query i'm using it.

in above mentioned example, arrival_dt 18-jun-2015 , departure_dt 21-jun-2015 , want start_dt in sequence starting arrival_dt till departure_dt 18-jun-2015, 19-jun-2015 , 20-jun-2015

for dataset day_num column appears sequence starting 1, can use expression: arrival_dt + day_num - 1 new_date calculate sequence of dates:

select t.*, arrival_dt + day_num - 1 new_date table1 t

generally following query can used generate sequence of values 1 x:

select level sequence dual connect level <= x

for example if want generate numbers 1 15:

select level sequence dual connect level <= 15

or when sequence -5, -4, -3, ...., 3, 4, 5 needed:

select level - 6 sequence dual connect level <= 5 - ( -6 ) ;

if want create sequence of dates 1 date another, calculate number of days between these 2 dates - substract these 2 dates. example when start date is: 2015-05-01 , end date 2015-05-05, query is:

select level + to_date('2015-05-01','yyyy-mm-dd') - 1 new_date dual connect level <= 1                      + to_date('2015-05-05','yyyy-mm-dd')                      - to_date('2015-05-01','yyyy-mm-dd')
