oracle 带 sysdate 的顶点时间戳间隔

Question

hi here i have a problem, i want to remove the expired entry from the table so I used the SQL where clause here is my SQL code

select ROWID,
       FOOD_RECEIVED_UID,
       USER_NAME,
       ITEM_TYPE,
       ITEM,
       QUANTITY,
       EXPIRY_DATE,
       CREATED_ON,
       CREATED_BY,
       UPDATED_ON,
       UPDATED_BY,
       USER_UID
  from FOOD_RECEIVED
   WHERE (ITEM_TYPE = :P9_ITEM_TYPE OR :P9_ITEM_TYPE IS NULL)and EXPIRY_DATE > SYSTIMESTAMP

Here is the photo copy:

could anyone help me to fix this...

Answer 1

Aren't expired products those whose expiry_date has already passed? < , not > .

and EXPIRY_DATE < SYSTIMESTAMP

Though, I doubt that expiry_date is a timestamp; looks more like a date , so:

and EXPIRY_DATE < SYSDATE

Answer 2

It isn't really clear to me what kind of solution you're looking for.

1. Do you want a SQL statement which removes all of the expired items in once?

   In that case, convert the select statement into a delete statement delete from FOOD_RECEIVED where....

2. Do you want a delete button in your report to remove them individually?

   Did you try to use the the APEX wizard to create the page? Create a Page -> Report -> Report with Form . Using that, APEX will create a modal dialog for you where you can delete the individual items.

Hope this helps you.
