How can i get just date from the timestamp data type.
Suppose i have a column timestamp with has data like "2011-05-16 16:19:22.579764-07" when i select from table i just want the date like 2011-05-16.
I'm trying to deduct x hours from a timestamp value. Everything works fine if x yields a result that is on the same day as the value I'm deducting it from. However, if it yields the day before then it gives the wrong answer using DML (although in SQL it works fine). Let me explain with an example:
Let's say current_timestamp is 20-MAR-12 09.40.00.000000 +00:00
If I deduct 8 hours from this I get the correct answer: 20-mar-12 01:40:00 (syntax: show current_timestamp-8/24)
If however, I deduct 10 hours from it (which takes it to the day before) I get garbage: 20-mar-12 00:20:00 (syntax: show current_timestamp-10/24). It should say: 19-mar-12 23:40:00
In SQL I get the correct result every time. So, my question is, is this a bug or intended behaviour? If the latter then what is it doing and how can I get it to give the answer I'm looking for?
What I'm trying to do is convert a timestamp from one timezone to another using DML. The NEW_TIME function will only give me what I want if I know whether the "to" timezone is currently in daylight saving or not. eg. Must I use CST or CDT?
The full syntax I'm using to try and achieve my aim is below.
show to_char( to_date( '2012-03-19--15-37-23' 'YYYY-MM-DD--HH24-MI-SS' )-(convert( extchars( tz_offset( 'AMERICA/CHICAGO' ) 3, 1 ) int )/24) 'YYYY-MM-DD--HH24-MI-SS' )
where 2012-03-19--15-37-23 is a user-supplied argument.
How do i insert or select date data type value in am or pm Eg 10:30:00 am or 10:35:00 pm

For example: 2012-05-28 22:36:08 and I would like to get format 28.5.2012 22:36:08
However I try to do it I get always some errors.

First, I'm aware that the equals (=) operator is a "comparison operator compares two values for equality." In other words, in an SQL statement, it won't return true unless both sides of the equation are equal. For example:
SELECT * FROM Store WHERE Quantity = 200; The LIKE operator "implements a pattern match comparison" that attempts to match "a string value against a pattern string containing wild-card characters."
For example:
SELECT * FROM Employees WHERE Name LIKE 'Chris%';
Here,I query about date type data on ORACLE database, I found the following, when I write select statment in this way:
SELECT ACCOUNT.ACCOUNT_ID, ACCOUNT.LAST_TRANSACTION_DATE FROM ACCOUNT WHERE ACCOUNT.LAST_TRANSACTION_DATE LIKE '30-JUL-07';
I get all rows I'm looking for. but when I use the sign equal =
instead :SELECT ACCOUNT.ACCOUNT_ID, ACCOUNT.LAST_TRANSACTION_DATE FROM ACCOUNT WHERE ACCOUNT.LAST_TRANSACTION_DATE = '30-JUL-07';
I get nothing even though nothing is different except the equal sign.
I have a table with two columns called startsem and gradsem they are both CHAR(3). Within those colums are rows that are listed as SemesterYear. For example, F09 is Fall 2009, S09 Spring 2009, and M09 is Summer 2009. I would like to create a constraint that says GradSem must be greater than StartSem b/c no one can travel back in time to graduate. However, as you know you can compare S09 > F09 because it will treat it as a string. I thought I could use a substring and compare the last two digits as a year and that would work but how do I compare the semesters as a time frame? Because in my schema F > S because Spring 2011 comes before Fall 2011 but in reality F < S because to Oracle it is a string and the ASCII value of F is less than S. I cannot chage the coding of the database so editing the rows so they are more date friendly is not an option.
So how can I modify this database to acruately compare StartSem and GradSem.
I have a table with modifieddate column with 'DATE' data type.I am facing date format exception and tried with to_char, to_date but its throwing invalid number exception. how to format date accordingly.

Is there a seeded function by which I can check all the rows which stored dates in varchar column.
I have a table say test (test_data varchar2(100));
Now I will insert all types of records into the table varchar,number dates and then i will write q query to etch all those records only which has dates only
INSERT INTO test(1);
INSERT INTO test('ABC');
INSERT INTO test(SYSDATE);
INSERT INTO test(TO_CHAR(SYSDATE,'DD-MON-YYYY'));
INSERT INTO test(TO_CHAR(SYSDATE,'DD-MON-YYYY HH24:MI:SS'));
INSERT INTO test('15/01/2012');

I have a timestamp field in an oracle table. The data in that field looks like this.
19-MAY-2011 10.55.21.628206000 AM
I want to query the data in this field by only date portion (not the time portion).
Something like this.
Select * from mytable where archivedate = to_date('19-may-2011','dd-mon-yyyy')
this query doesn't return any data. But actually there is data for 19-may-2011 (along with time portion) in that field.
how to query based on only date portion?

Due to some business requirements a table field needs to change from date to timestamp in order to handle the millisecs.
1>When i alter the row , for a table with 150 million recs will there be a conversion. Is there a recommended way to convert the field. Mind you this field is used as a part of composite PK.
2> There is a interfacing application which connects and copies the data to its system and is using the date type, will that application be able to continue to work without any changes, if it does not care about the millisecs.
3> Will there be performance impact on an existing application that uses the date field to sort
4> Will DB need more space due to the change
I have a column where I have time stamp with date and time(8-May-10 10:20:55 Am) from that i will get only time(10:20:55 Am)[query for this mentioned below] Now i need to append the time to current date and insert into a Timestamps column only .
so my result should be 17-May-11 10:20:55 Am(Assuming current Date is 17-May-11) . I tried search it by i found a way in sql server by using DataAdd and DataDiff .
query to get the time is:select to_char(to_date('11-MAY-11 05.00.00 PM', 'DD-Mon-YY HH:MI:SSAM'),'HH24:MI:SS') "Time Now" from dual

I am working with Oracle 8i and I have a problem while applying the below query:
select to_char(ENTRYDATE,'MM-DD-YYYY HH24:MI:SS') from TBL_BANDWIDTH_READS
where ENTRYDATE > sysdate-1

The time appears as 00:00:00. I said it's something weird because if I take the where condition off, then something like this appears:

I checked the DDL of both tables and the only difference is that the TBL_XX_PROGRAM have the ENTRYDATE field defined as not null and the ENTRYDATE on the TBL_BANDWIDTH_READS does not have the same constraint, could it affect?

My questions are
1) what is significance of '.' here? insert into t values(timestamp'2011-03-24 11:03:00.05','12-mar-2011 11.03.00.055',systimestamp,localtimestamp);
2) while inserting using "values(timestamp'2011-03-24 11:03:00.05'" where this yyyy-mm-dd hh24:mi:ss.FF format comes from?
3)what is role of nls_timestamp_format of nls_database_parameters in this? how it allowed me to insert value "'12-mar-2011 14.03.00.055'" which has hh24 format?
4) Does the format of localtimestamp is decided by nls_database_parameters?
Note : I have not set nls_date_format in my session
