42,470
Solution 1
try this:
variable var DATE
exec :var := '15-OCT-13'
and then your select with using :var in it
Solution 2
I have found a way to add variables for the sql query as follows
DEFINE RES_DT = TO_DATE('11-AUG-15');
And also to access the variable through the query we have to use '&' notation as follows
select * from customer where assign_date = &RES_DT;

Hi I am trying to declare a variable to use in Oracle SQL select query as such:
DECLARE myDate DATE; BEGIN SELECT Source as "Source", DT as "Date", Status as "Status", COALESCE("Count", 0) as "Count" FROM (Huge SubQuery that includes many WHERE date between x and y); END;
I need to use myDate for the query so I dont have to update it in 10 places everytime I run the query. Basically its just for declaring a variable that can be used in a where date is between clause in several places.
