Add new tag Blogroll installation sql developer

raptor early adopter release 4 is out

Well, it is now renamed to SQL Developer.

There is now an expected “Save password” checkbox to save the password… apart from the name, it looks quite similar to raptor 😉

to_char(interval)

There is no to_char function available for intervals.

Or at least it does not work as expected

SQL> select to_char(interval '1234' second, 'HH24:MM') from dual;
TO_CHAR(INTERVAL'12
-------------------
+00 00:20:34.000000

I just write my own one, with some new format elements

For interval day to second, I have DDD number of days, HH number of hours (0-24), HHH total number of hours (0-99999999999999), etc

here it is

grid control release 2

I am waiting for eomgc 10gR2 for AIX so I check the download page often. Instead of adding new plateforms, I notice they just removed Solaris !
