Example For Conversion Functions
Mar 27, 2012Again 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
SQL & PL/SQL :: Oracle Date Conversion Errors
Mar 14, 2011I am having a strange issue with date conversion. The errors encountered are :
PLS-00382: expression is of wrong type
PLS-00306: wrong number or types of arguments in call to '>'
The situation or test case is as follows:
create table sand_programs(prog_code varchar2(20), prog_end_dt date);
create table sand_program1(prog_code varchar2(20), filing_date number(15));
Result : Both the tables are created.
Now I create a procedure below as mentioned, to check if the filing_date is greater than the prog_end_dt or not.If the filing_date is greater than prog_ end_dt, then it should go to the 1st "dbms_output.put_line" message else it should go to the 2nd "dbms_output.put_line" message.
Here's my procedure:
create or replace procedure test_sand(p_program_cd in number) is
v_prog_end_dt date;
v_filing_date number;
begin

SQL & PL/SQL :: Date Conversion From Unix To Oracle
Jun 14, 2010I have a UNIX shell script as following,
#runs the selected process

set pause off
set verify off
set pagesize 0
set linesize 2000

I am passing a Date to the Oracle Procedure in `date +'%b_%d-%H:%M:%S'` format.
rmsqa813.2 /home/ashlaksh> echo `date +'%b_%d-%H:%M:%S'`
Jun_14-02:26:37
The oracle Procedure's SQL is as following,
SELECT ffdh.fiscal_doc_id INVOICE_ID,
ffdh.location_id LOCATION_ID
FROM fm_fiscal_doc_header ffdh,
fm_schedule fs
[code]........
The above SQL is not getting the data as the Date format "AND ffdh.last_update_datetime <=i_last_update_datetime " is not matching..
Do I need to convert the Date ? ( But i_last_update_datetime is DATE)
SQL & PL/SQL :: Oracle Date / Time Zone Conversion
Aug 13, 2012I would like to know how to convert the following:
13-AUG-12 03.30.06.146 PM
to the format:
"MM/DD/YYYY HH:MI:SS AM"...
I believe there is a time zone issue here as well, since the should actually be around 11:30am. I am not sure what time zone is being used.

SQL & PL/SQL :: Date Functions?
Dec 3, 2012Trying 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?
Epoch Date Conversion
May 31, 2011My 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.

SQL & PL/SQL :: Date / Time Conversion
Apr 4, 2010I 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

SQL & PL/SQL :: Conversion Of Julian Date Into Dd / Mm / Yyyy
Mar 8, 2010I 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'.

tell me a way to convert this Julian to mm/dd/yyyy format to be inserted into a table in Oracle.
Tried this :-

Date To Timestamp Conversion Of Column With 150 Million Rows?
Oct 5, 2010Due 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

SQL & PL/SQL :: Migrate Sybase To Oracle Conversion
Apr 23, 2010i want to migrate sybase stored procedure to oracle stored procedure.
sybase stored procedure:
create proc checkcontract @titleid tid
as
delete from titile where titile_id=@titleid
return 0
we need to migrate this procedure to oracle stored procedure. If we are using return 0 in SP in oracle means, it returns the end of the procedure statements(according to oracle statements). but sybase indicates that return 0 does not return 0 value during the run time. The return 0 implies that SP completed successfully. In oracle, i have converted stored procedure into SP and also stored functions.
Oracle Scripts:
Stored Procedure:
create or replace procedure checkcontract(v_titile varchar2)
as
begin
delete from titile where titile_id=v_titleid;
end;
/
Stored Functions:
create or replace functions checkcontract(v_titile varchar2)
as
return number
begin
delete from titile where titile_id=v_titleid;
return 0
end;
Give the comments which one is correct or accurate.
Oracle SQL developer also recommeds STORED FUNCTION. But in my application code, don't assign any output variable to this procedure. If i am using Stored Functions, we need to assign value and assign the output of the SF. we don't want to change the application code.

As you can see, it's split the entries into date ranges. If there is a 'lone' date, the 'period start' and the 'period end' are the same date.
