Again i getting confused with conversion function especially Explicit data type conversions. some cases oracle server automatically converts the data to the required type. This is called IMPLICIT CONVERSION. Explicit conversions are done by using the conversion functions.
Oracle Explicit Data Type Conversions are
1 TO_CHAR
2 TO_DATE
3 TO_NUMBER
the data in the column is in below format
---------------------
2/10/2009 9:28:41 PM
mm/dd/yyyy
my requirement is
--------------------
20090210
YYYYMMDD
Some app (wich I can't touch) stores a value that I need to modify with a trigger or even with a view.
Original value: 7B751BF0 (2071272432 in decimal)
Stored value: 4028331387 (F01B757B in hexa)
To make things short, I'm getting 4028331387 and I need to convert it to 2071272432.
I need to move one of my LMT tablespace to DMT, Can I do it , I know that the DMT's are depreciated since Oracle 9i but still need to know this.I am trying the below mentioned method to achieve the same.

I have a table that looks like this...
APPOINTMENT
APPOINTMENT PATIENT DENTIST PROCEDURE AMOUNT
NUMBER NUMBER ID NUMBER DATE BILLED PAYMENT
20000001 3001 27 33100 11-Feb-2000 405.00 405.00
20000005 3988 23 11201 05-Mar-2000 80.00 0.00
[code]...
and i used this to find which dentist had the least appointment
select min(count(dentist_ID)) as "Minimum Number of Appointments" from appointment group by dentist_ID;
and this shows..
Minimum Number of Appointments
------------------------------
2
if there's a way where I can show the dentist's ID that corresponds to this "min number of appointment" i tried doing
select dentist_ID, min(count(dentist_ID)) as "Minimum Number of Appointments" from appointment group by dentist_ID;
but it gives me this error
ERROR at line 1:

I have an issue with date conversion. In my table dates are in this formate:

I have a table datatype number (12,10) that I am reading out of. I am taking the value from this source table and inserting it into a destination table of datatype number (12,15).
I do not have the ability to alter the tables. How can i convert this number so i can insert. I am currently getting the error "ORA-01438: value larger than specified precision allowed for this column"
I am trying to use the to_number, but it not working. How can i format this number field so i can read it from source where i have number (12,10) and insert it successfully in a higher precision table of number(12,15)

I am using Oracle 11g
I would like to use character functions (LPAD, INSTR, SUBSTR, etc) to accomplish what i feel should be rather easy. I would like to take the following character strings:
'ADAM ST #3 S_109640'
'ALBANY AVE #5 & #6 S_AL5&6'
'ALBIN RD #10A S_123318'
And make them
'ADAM ST'
'ALBANY AVE'
'ALBIN RD'
As you can see, it probably boils down to using SUBSTR, INSTR, RTRIM, and LENGTH??
analytic functions regarding the ORDER BY part =)

why is that i just added ename on the ORDER BY part of the DENSE_RANK and then

ADAMS and WARD we're removed from the result, why is it? did it rank it as UNIQUE per sal and ename?
Trying to understand how Oracle DATE works and how it differs to TO_DATE in the below manner...
SELECT DATE '2012-10-25' FROM DUAL;
SELECT TO_DATE('2012-10-25','YYYY-MM-DD') FROM DUAL;
I've had a look through the Oracle Docs but can't find much on this. Basically I want to know how safe the first option is and if it does the same as the second. Also, where does DATE get the Format String from (NLS setting?). Can it be employed to compare a literal with a date that has a TIME portion set to something other than 12:00:00?
count the no: of emp working under each manager? and instead of manager number display the manager name

DECLARE @StartYear AS INT = 2010;
DECLARE @EndYear AS INT = 2014;
WITH
years
AS (SELECT YYYY = @StartYear

SELECT yyyy + 1

My company uses Remedy which stores date/time as an integer. I use the following formula to convert it to a readable date:
TO_CHAR(TO_DATE('01/01/1970', 'MM/DD/YYYY HH:MI:SS AM')+ ((createdate - 4*3600)/(60*60*24)),'MM/DD/YYYY HH:MI:SS AM') as Create_Date
I have to use the "4*3600" in order to get the date to show up correctly, but even then the date sometimes comes up wrong. If the date occurs in the morning, then the date shows up as the previous day. I am sure this is probably due to the offset I am adding in the above formula. If I don't add the 4 hour offset, then the date shows up 4 hours off.
I have coluum value like 00000000399. i need to convert the float like i mentioned
00000000399 should be loaded as 3.99
00000001197 should be loaded as 11.97
00000000003 should be loaded as 0.03
wat option i try to change the value
is there any licensed version tool available to convert objects from sql server to oracle especially procedures? I have tried with open source tools but that tool didn't convert properly.
View 7 Replies View RelatedThis is my query:
DELETE FROM GR_GUEST WHERE GUEST_NAME='Ambassador Jack Binns bring Patrick Clawson' AND RESERVATION_ID_FK=21635
It gives an ORA-01460 which is "unimplemented or unreasonable conversion requested"Removing the " AND RESERVATION..." gives the same error.
The problem is that GUEST_NAME is a VARCHAR (150) and RESERVATION_ID_FK is an INT so I don't see where any conversion is coming in.I had changed the name a little bit as it used to a (, ) and a : in the GUEST_NAME. I thought that might be causing the issue so I removed them with a REPLACE through an UPDATE query. However, the record still needs to be deleted.
It should be a simple query as it happens on this table all the time, so I don't know why this one is different.
1075329297.572
This is unix time where 1075329297 is seconds 572 is milliseconds.
first il store this time in oracle database.when i am retrieving it i want this date into yyyy-dd-mm format. Is it possible to do it in oracle.(using convert function) or is there some other way?
converting a string to date, my string looks like '01022013' '04022013', I tried to_date('01022013', 'dd-mm-yyyy') but couldn't work.

I am converting sybase to oracle database. during the migration, i have small doubt in triggers.
sybase source
create trigger testss_dt
on test
for delete
as
if @@rowcount = 0
return
insert into test
select id from deleted
return
I have converted oracle code here
create or replace trigger testss_dt
before delete on test
for each row
begin
insert into test
values(:old.test);
end;
But i have ignores @@rowcount concepts in oracle. what @@rowcount indicates in trigger?
I want to change a table datatype from date to number where already existing data should get convert.any possibility of doing where i tried like this but no get changing. Even as Julian format is working a bit i want the data to come as GMT format
Scenarios where i tried are like this.
ALTER TABLE Contacts ADD ALERT_DATE1 NUMBER(20,0)
/
UPDATE Contacts SET ALERT_DATE1 = TO_NUMBER(ALERT_DATE)
/
ALTER TABLE Contacts DROP COLUMN ALERT_DATE
/
ALTER TABLE Contacts RENAME COLUMN ALERT_DATE1 TO ALERT_DATE
/
but second statement failing.
Julian fomat like
SELECT sysdate,
TO_CHAR(sysdate, 'J'),
TO_DATE(TO_CHAR(sysdate, 'J'),'J')
FROM dual;
I have two cases
i . Convert Image to Hex String
ii . Convert the Hex Sting to Image
Case i is done, is Case ii is Possible in Oracle 11g Rel 2..?
My application spools the data from database into file and file is fixed length. My application working fine when database has single byte characters. But I am getting fields postion misposition and length mismatch in spooled line when data base has Multi byte characters(ê).

I am converting data from an old paradox table to a new oracle table, one of the problems im having is incompatibility with date and time formats:
some columns contain times in the format : "00:00:00" eg..... "15:00:00"
some columns have date in the format: "dd/mm/yyyy" eg....... "21/08/2000"
some columns have time and date eg.. "05/09/2000 15:49:39"
Currently I have the data held in tables within an access database, and in CSV format.
eg, I have dates like 03/04/2010 which i need to be 03-APR-10....
how I can get the following into Oracle date formats? there is over 1000 records so manual conversion is out of the question
I recently became involved with databases, and i've came across with a little obstacle. I have strings that represent a date, they are very oddly formatted and need to store them as dates. the string format looks like this: 'Monday, May the 13th of 2001'
How can i effectively convert them to DATE type?
