Attention: To align with new corporate security policies, and to match policies adopted by other communities within Oracle, the My Oracle Support Community access requirements will change beginning September 18, 2025. MOSC will now require that member accounts in our community be associated to a *corporate* email address. This means that users with generic domains (such as gmail.com, yahoo.com, and others) will no longer be granted access to the discussion forums and ideas labs. If this policy affects you, act now to change the email address that is associated with your Oracle (and community) account. Alternatively, you can opt to create a new Oracle account that uses your corporate email domain.

Why PS Query converts a date field to character when used in an expression

Hello,

I am trying to frame a simple query using PS Query. It is find the number of days between 2 dates. The query is

SELECT A.EMPLID, (A.END_DT - A.BGN_DT) + 1 FROM PS_GP_ABS_EVENT A

However, when I create an expression as A.END_DT - A.BGN_DT, PS Query converts it to TO_CHAR(A.END_DT,'YYYY-MM-DD') - TO_CHAR(A.BGN_DT,'YYYY-MM-DD').

This results into the query going into error. I have tried this using various methods, but none of them works.

So, what is the right way (as per PS Query) to perform operations on dates and use them as fields.
