Input parameter as period name

Question

hi..
when u give the input parameter as period_name(eg;DEC05)
form period name and to period name as input parameters ,it displays the out put
for the period name which doesn come under the limits specified
how will u link the corresponding date of the period name in the query
the example is like this
ps.PERIOD_NAME >= :from_period
AND ps.PERIOD_NAME <= :end_period
where the period name is the field which contains
DEC O5, JAN 06 AS DATA
when this data is given as input it doesn take since it is in character format
and produce the result for other period names too, now
my prob is how to link the period name to appropriate date which exist in the table
but u cant give the date as parameter
ie for eg dec-05 has a date
how to link it,
if the user gives the input parameter as dec05 it should go link the date
and produce the appropriate result

Okay! Now I got it. There are 2-3 cases here.
If your period_name is a date field, then do this
where period_name >= to_date(:p_start_date, 'MONYY')
and period_name <= to_date(:p_end_date, 'MONYY')If your period_name is a varchar field, then
where to_date(period_name, 'DD/MM/YYYY') >= to_date(:p_start_date, 'MONYY')
and to_date(period_name, 'DD/MM/YYYY') <= to_date(:p_end_date, 'MONYY')-- Remeber you have to use the exact format of the date in the varchar field. I've just gave an example for DD/MM/YYYY.
