I have a requirement in which a particular a timestamp column (date1) whose values are in CET timezone needs to be converted to EST and day light savings should be taken care of in the conversion logic. I should not use any ddl statements for altering the timezone and all.

how to subract the timestamp values.
SELECT TO_TIMESTAMP ('10-Sep-02 14:10:10.123000', 'DD-Mon-RR HH24:MI:SS.FF') FROM DUAL;
This is my output.
TO_TIMESTAMP('10-SEP-0214:10:10.123000','DD-MON-RRHH24:MI:SS.FF')
---------------------------------------------------------------------------
10-SEP-02 02.10.10.123000000 PM
Now how to subtract the FF value in sysdate.(ex:10000 this is the input of FF value )
example output like: "18-APR-12 09.46.44.005196 AM"
I want to have sum of Time Stamp Values in a Table. i.e. Group by Query

I have Time values in character column of a table. i.e. Table TT column t1 char(5) values '03:02'
Above mentioned values in more than one line, i want to get the sum of all the values and it should be a time value.

how to extract DATE from timestamp column
View 2 Replies View RelatedI have a table A with a column B timestamp(6). The tables contains around 300000 rows..I have created index 'idx' on the column B.When i compare column 'B' with systimestamp, it does not use the index, whereas if i compare 'B' with sysdate it uses the index.
Eg :
select count(*) from a where b<=sysdate;
The above used the index 'idx' and executed in 1 second
select count(*) from a where b<=systimestamp;
The above does not use the index and executed in 19 seconds.
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
My scenario is to insert values into 'out' column by comparing 's' and 'IP' columns of temp table.The exact situation is at first need to go to ip column,take a value and then go to source column and check for the same value of ip which is taken previously.Then after corresponding ip of that source column should be inserted back in previous source column.
The situation is marked clearly in file which i am attaching with '--' comments at respective places.I am also pasting the code which i tried out,unfortunately it is giving error as exact fetch returns more than requested number of rows since there are duplicates in the table.I tried it using nested for loops.Also implemented using rowid,but it didnt work.
fixing the errors or if there is any new logic that can be implemented.
DECLARE
i_e NUMBER(10);
BEGIN
FOR cur_1 IN(SELECT IP from temp where IP IS NOT NULL)
LOOP
FOR cur_2 IN(SELECT IP from temp where s=cur_1.IP)

On my APEX page i have region which has sql query as source and it displays as HTML table the query result to the user.
I want to display addinonal column with a hyperlink inside, and that hyperlink would have CGI/URL-parameters which contains the other values of the HTML row.
So, let's say my APEX region queryes columns as "select c1, c2, c3, c4 ..." and displays out values "V1, V2, V3, V4" then i want to have addional output column with such hyperlink:
a href="f?p=100:7:13467554876288::NO::c1,c2,c3,c4:v1,v2,v3,v4">My link column with CGI-parameters</aHow can i create such hyperlink?
The overall idea is that the link would forward to a page which loads those values "v1,v2,v3,v4" into form fields and user can proceed from there.

I want to pass multiple column values of a row in an interactive report page to hidden items in another page through column link. And I did it successfully. However, I found I need to pass more than 3 columns of a row in this report, while a column link only permits me to pass 3 column value at most. Is there anyway that I can pass more column values to hidden items in another page?

I am facing issue related to Number data while it is being converted to Varchar2, it is automatically getting rounded off after 32 decimal place.My database version is "Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production".
1) create table test18 ( col1 varchar2(10), val Number);
create table succeeded.
2) insert into test18 values ('First', -347026.6408499652467480885711448714129679); -- After decimal 34 digits
1 rows inserted
insert into test18 values ('Second', -347026.64084996524674808857114487141296); -- After decimal 32 digits
1 rows inserted
3) select * from test18;
COL1 VAL
---------- ----------------------
First -347026.6408499652467480885711448714129679
Second -347026.64084996524674808857114487141296
4) As per the requirement, all the columns would need to be concatenated as a single string along with comma delimiter
select col1 || ',' || val as record_string
from test18;
RECORD_STRING
---------------------------------------------------
First,-347026.64084996524674808857114487141297
Second,-347026.64084996524674808857114487141296
"First" string got rounded off to 97 (last 2 digits) instead of 9679 but for "Second" record it holds the actual value.Only thing which I could figure out while the number is getting type casted to String, it is getting rounded off to 32 decimal place.throw off some light on it and provide the solution how the original record can be kept intact without rounding off.
Expected Output_
RECORD_STRING

I need the timezone of the server that the DB sits on. I don't want the offset. I need the region name. This is because some regions use daylight savings time and some do not. Plus an SA can change the time of the OS. Another company manages our servers and DBs in production and we don't have contact with them. We could use a lookup talbe and just populate it, then update it when we find out what it is in production. The problem is that I have seen cases where the timezone on servers change. Considering the lack of contact between the teams, we really need a reliable way to get the timezone out of the DB.
We tried several ways. My list is below and I explain why this is not working.
examples:
sessiontimezone: this is the timezone of my server. In theory it should be the same as the DB. We cannot take the risk that this will be out of sync. dbtimezone: This gives the offset. Such as -5:00 for US EST. There are multiple regions that have this. Some do not use daylight savings time and some do. We would need America/New York instead.
sessiontimezone gives the timezone setting for the client. This can be altered.
dbtimezone just gives the offset such as -5:00
We get data feeds from different parts of the world. We get some data based data that is local to that regions timezone. We need to partition on this field. So we need to add a field to the DB and normalize it to the time local to our DB Server. So if we get a record from california and the DB is on a server in US EAST, we add 3 hours. The offset won't work...
1. a timezone that we are getting from may not be in daylight savings time. We are partitioning by hour.
2. We would hit daylight savings time in New York before we hit it in California, so we would need to account for that in the math.
This hourly partition is a fixed and hard requirement. We need this to be absolutely accurate.
Here is what we tried:
What I want (pseudo-code): “Select XXX as timezone_region_name” to return “America/New_York” or “UTC”. It may be that the timezone was not set for the database at install time, and if it were, these queuries would work.

I have an interesting problem. I have a server in the UK and I have three databases globally - UK (FINUKQ1), NY (FINNYQ1) and TK (FINTKQ1). The NY and TK databases will be migrated to the UK server as part of a consolidation project. Obviously, Time Zones and DST are the biggest concern for me.Here was my plan for the implementation (concentrating on Time Zone/DST issues).
Added to .profile:
--------------------
if [[ "$ORACLE_SID" = "FINTKQ1" ]]; then
export TZ="Asia/Tokyo"
elif [[ "$ORACLE_SID" = "FINNYQ1" ]]; then
export TZ="America/New_York"
else
unset TZ
fi
echo "TZ=$TZ"
Once environment has been set start database and listener.
Change database TZ:
-----------------
alter database set time_zone='Asia/Tokyo';
alter database set time_zone='America/New_York';
Check database TZ:
select dbtimezone from dual;
Add trigger:
------------
CREATE OR replace TRIGGER sys.timezone_check
AFTER startup ON DATABASE
DECLARE
[code]...
The trigger was there to put the database in restricted session if it is started in the wrong TZ and an error written to the alert log. The check was done on the dbtimezone and the dbname. Quite simple. Only issue is that it doesn't work as I wanted as dbtimezone and TZ are separate and disparate entities. i.e. I can start the TK database up in UK time (which will be incorrect for this project), and check the dbtimezone and it will show as 'Asia/Tokyo'.
Is there a better way of checking? Any trigger like this to compare TZs etc?
I am using the below query to get time stamp along with time zone format.
>>SELECT CURRENT_TIMESTAMP FROM DUAL
Now the requirement i got is i need to get convert the format in DD-MON-YY, HH:MM:SS, Timezone (GMT or PST)
how to convert this format. Or is there any alternative time stamp option to do conversion.
I've written this code to present the problem:
declare
region_date varchar2(100);
region varchar2(100);
offset_result varchar2(100);
begin
region_date := '2013-04-07 01:59 Australia/Sydney';
region := 'Australia/Sydney';
select
to_char(
[code]....
What I want to do is to use the variable "region" for the timezone specification as well,And I seem to be unable to, and don't understand why.....
why when I get an "ORA-00907: missing right parenthesis" with this value,Whereas, it works when I put "AT TIME ZONE 'Australia/Sydney'" there?
I have one issue My server is in france and it is in french timezone but when I query for sysdate it returns US time.
In '/etc/sysconfig/clock/'
Zone= europe/paris
UTC= true
echo $TZ variable is returning nothing.
sysdate = us time
systimestamp= us time
current_timestamp = french time
current_date = french time
dbtimezone= europe/warsove, sessiontimezone=+2.00( which is also europe timezone offset)
tz_offset(dbtimezone)=+2.00, tz_offset(sessiontimezone)= +2.00 i.e europe
os timezone= europe/paris.
This command "./emctl config agent getTZ" is also returning timezone as europe/paris
Also in "emd.properties" file "agentTZRegion" parameter is set to europe/paris
Oracle version= 11.2.0
Now I don't understand why this sysdate and systimestamp is returning "US time zone" while everything else is returning french time zone.
I'm in the process of testing a restore/recover from a simulated full system and media loss. A level 0 backup was taken from the server, and I'm trying to restore/recover to a point in time on a second server. I have created the database (with the same name) and have been able to successfully restore both the controlfile and spfile from the autobackup.
how does RMAN treat the "set until time"? The level 0 was taken on a database/server that is in CST while the database I'm trying to do a restore/ recover to is in EST. So when trying to do a point in time recovery, should I specify the time in EST or CST?
I'm going to migrate my current db 9.2.0.8 (Timezone version is 1!) to a new server 11.2.0.3, so I was wondering if I must upgrade timezone version of my current 9iR2 to version 4! Before upgrade it...Btw my new server has timezone v14.
