How to extract only date value from date field in Oracle? [duplicate]
(3 answers)
Closed 7 years ago.
I know this is simple but am having great difficulty, I need to take a query field that is datetime and convert it so that it is only date no time.
SELECT COSTLABR.CHARGDTTM
FROM imsv7.costlabr
Gets me the datetime field from chargdttm but I need it to only be date, or as an alternative the time to be exactly the same for every row returned.
This has got to be simple but it is eluding me.
Thanks in advance!

You can use the TRUNC function to truncate dates:
SELECT TRUNC(COSTLABR.CHARGDTTM)
FROM imsv7.costlabr
will set the HOURS, MINUTES, and SECONDS portions of the date column to zero, in effect changing the time to the preceding midnight.

I have an entire column that I would like to change from a complete datetime field to display only the mm-yyyy.
Don't store it in database. Let your column stay as datetime datatype use the below code to display the date in mm-yyyy format
Select right(convert(char(10),getdate(),105),7)

How to update datetime field and remove date part from the value in SQL? [duplicate]

How to get Time from DateTime format in SQL?
(19 answers)
Closed 7 years ago.
I have one column in my Table with DateTime as its datatype.
Now I would like to remove the date part from the datetime column, and update the same column with only time part contained in it. How should I proceed?
Below is the column value :
1900-01-01 01:43:00.000
Expected value after update would be :
01:43:00.000
If you use SQL Server from version 2008 onwards you can use
SELECT CAST('1900-01-01 01:43:00.000' as TIME)
For earlier versions, use
SELECT CONVERT(VARCHAR(20),'1900-01-01 01:43:00.000',108)
You can use this query for getting time from datetime format.
select cast(yourdatetimecol as time) [time]
from yourtable

I'm trying to find the difference between a TIMESTAMP(6) field and a DATE field in oracle sql to return number of days.
Anyone know how to convert these?
i tried to_date, to_number and a few other functions. I actually got it to work by using trunc on my datetimestamp
(a.date- trunc(b.datetimestamp))

I am using following query but it doesn't provide any meaningful output:
Select Cast(versionno as bigint) from BranchDetail
The value in Version column is like this : 0x000000000D2537F7
A TIMESTAMP has nothing to do with date and time. See this question. It is a ROWVERSION, not a date/time value.

I have my datetime column in table defined as Oracle NUMBER data type which contains data in this format 1363709957 for example.
I want to get these numbers in query so i can execute my insert scripts which will put in current time in there. What is the oracle SQL for that?
Your time stamp appears to be a standard Unix time stamp. You need to use arithmetic to convert this here's a post on OTN about this,
and one for the other direction.
