Oracle Session Set Time

Dear Experts,

There is a way to set the timezone for session by using - alter session set time_zone = '+02:00'

Is there a way to set the date&time for session?  The result would be that a "select sysdate from dual" would yield a value relative to the the date&time set.

The end result is that I want to set the date&time to JAN15 and run a test based on that time.  I am not able to change the server time because it will impact others using the server.

Thanks,

Bill

You cannot rewire sysdate.  It makes a hard call to the OS.

The one exception at the database level is FIXED_DATE:
http://docs.oracle.com/cd/E11882_01/server.112/e25513/initparams093.htm#REFRN10062

This will leave the servers date alone but everything in the database will think it is that date.

Hi slightwv,

This is so very close to what I need... But, it acts at the SYSTEM level and impacts everyone on the database.  I am looking for something that acts at the SESSION level.

Thanks very much.  I did learn something new.

I don't know of a way to have the session alter a call to sysdate.

I did see where someone wrote their own function mysysdate that returned a specific value but you would need to change all your calls from sysdate to mysysdate.

Can you not create a new 'test' database for this testing?  Then you can set it to whatever you want.

Hi slightwv,

I am doing some work for a large company.  It takes a long time to set things up.  Lots of paperwork.  We know the code works today (with day light savings turned on).  But, we dont know for sure what will happen in November (after day light savings is turned off).

I was looking for a way to test TIMESTAMP with LOCAL ZIME ZONE columns.  If we cannot do that then we will GO LIVE in 2 weeks.  In the meantime, we will setup the dedicated test server and change the date and the test to make sure the code works... prior to the November of course.

Thanks for you assist,

Bill

I was looking for a way to test TIMESTAMP with LOCAL ZIME ZONE columns now.  If we cannot do that then we will GO LIVE in 2 weeks.  In the meantime, we will setup the dedicated test server and change the date and the test to make sure the code works... prior to the November of course.
