how I can avoid PLW-07204 "conversion away from column type may result in sub-optimal query plan" (or rather the problem notified here by Oracle) from my PL/SQL code.My code looks as follows:
create table T(D date);
create or replace procedure P is
cursor C(D_IN IN DATE) is
select D
from T
where trunc(D)=SYSDATE;
begin
null;
end P;
[code]...
I don't want to disable the warning - it is there for a reason.
Additional description for the issue: It seems that D is of typ=12, while trunc(D) is of typ=13. You can use DUMP to read this info. This is described at URL....

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

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 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)

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

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.

This 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.

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 want to convert the multi byte characters into single byte while spooling the data( ê ==> e)
The below query has converted the multi byte to single byte character. But actual value is modified into lower case.

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

How can i effectively convert them to DATE type?

I have been given some data in excel sheet to be uploaded in an Oracle Table. The dates are in Julian. The date in Julian in excel sheet is as :-'110048'.
In the excel file, I found that the cell was formatted as General and when I changed the formatting to Date I got the result as '19/04/2211'.
tell me a way to convert this Julian to mm/dd/yyyy format to be inserted into a table in Oracle.
Tried this :-
SQL> SELECT to_char(to_date(to_char(110048), 'J'),'DD/MM/YYYY') FROM dual;
