Expose your Local Development Environment to the outside world with Ngrok

Disabling of Password Expiration in Oracle Apex(Internal Workspace Admin)

This post was inspired by a  question  on the OTN APEX forum, which contains how to  reset set the password of the  Oracle Internal Workspace Admin    and  Set the account never to expire  The first bullet has so many blogs  talk about how to reset the password of the Internal Workspace.

How does one add a day/hour/minute/second to a date value?

DATE is the datatype that we are all familiar  with when we think about representing date and time values. It has the ability to store the month, day, year, century, hours, minutes, and seconds. It is typically good for representing data for when something has happened or should happen in the future.  The problem with the DATE datatype is its' granularity  when trying to determine a time interval between two events when the events happen within a second of each other. This issue is solved with the TIMESTAMP datatype. In order to represent the date stored in a more readable format, the TO_CHAR function has traditionally been wrapped around the date: SQL> SELECT  TO_CHAR(hiredate,'DD.MM.YYYY:HH24:MI:SS')  "hiredate"   FROM employees; hiredate ------------------- 17.12.1980:00:00:00 20.02.1981:00:00:00 The SYSDATE pseudo-column shows the current system date and time. Adding 1 to SYSDATE will advance the date by 1 day. Use fractions to add hours...
