greyed out Print button in file explorer with .htm Extension windows 10

Hello,

There are options you can consider to troubleshoot this issue. When the
Print button on the File Explorer window is greyed out, we suggest that you check if the
Print Spooler service is running. To do this, simply follow the steps below:

• On the Cortana search box, type Services and click the
  Services app.
• Scroll down and check if the Print Spooler service is running.
• If not, right-click Print Spooler and click Properties.
• On the Properties window, click Start.

After following the steps, check if the Print button
is already available.

Should you have further questions, feel free to post them on this thread.

 

SQL HELP-ORA-04073 column list not valid for this trigger type

Hi,

After trying to create this trigger:

CREATE OR REPLACE TRIGGER a
AFTER INSERT OF duration, startdate ON route, outing
FOR EACH ROW
WHEN (NEW.startdate LIKE %jan%)
AND (NEW.duration = 5)
DECLARE
closed_in_jan EXCEPTION;

EXCEPTION
WHEN closed_in_jan THEN
RAISE_APPLICATION_ERROR (-20101,We are closed in January.');



I get this error:

ORA-04073 column list not valid for this trigger type
Cause
A column list was specified for a non-update trigger type.

Action
Remove the column list.


I've tried researching but can't find out what a column list is!

Any help would be appreciated, thanks.
