[foam original] Oracle removes Date without using to_char every minute, and then to_date is so troublesome.
1. Do you encounter the Datetime type in Sql writing and just want to keep it until the date is removed?
2. Do you need to transfer date to varchar and then back to date?
Now, tell all the relatives: don't bother so much!
Select trunc (sysdate) from dual-2013-01-06
Directly OK, from then on light pack, take you to pretend to take you to fly.
