To_date function from dual
Hi All,
i have issued SELECT TO_DATE('07:19:47', 'HH:MI:SS') FROM DUAL
in toad, and got the below output.
11/1/2007 7:19:47 AM
Even sqlplus returns
TO_DATE('
01-NOV-07
Can anyone explain why this wont show sysdate? thanks
If I understand correctly, you're wondering why
SELECT TO_DATE('07:19:47', 'HH:MI:SS') FROM DUALreturns a date of Nov. 1 instead of today (Nov. 2)
Interesting - I get the same result on 10gR2. Selecting SYSDATE gives me back today's date. I tried Justin's suggestion to alter the NLS_DATE format (didn't see why RR would affect the day, but tried it anyway) but this did not affect the result.
I think the default day the query is converting the date string to is somehow being evaluated one day behind, as sysdate
sql>run
1* SELECT to_char(TO_DATE('07:19:47', 'HH:MI:SS'),'mm/dd/yyyy hh24:mi:ss') FROM DUAL

Executing DML-ing stored function from EntityManager
Hi,
Is there some way of getting the result from a DML-ing stored function from the EntityManager? I can use a native query and just select the function from dual if it doesn't do any DML but when it does, it is not permitted. I can't use getDelegate() to get the raw connection either :-/

Function in Select...from dual
Hi
One generate question.
We can do the following task in the Select Statements:-
1. Select Function_Name('Parameter) from dual;
2. Select Package_Name.Function_Name('Parameter') from dual;
Why dont we can call the procedure from the Select Statements:-
Select Procedure_Name('Parameter') from dual;
Can we we call the Procedure in side the procedure statements ???
Thanks
SandeepProcedure or function, it's not an Oracle question. In all prog language, it's same.
Where a function return one value into a variable (or query here) :
declare
var_in1 varchar2(10);
var_in2 varchar2(10);
var_out varchar2(10);
var_out:=myfunction(var_in1,var_in2);
print var_out;
--or
print myfunction(var_in1,var_in2);a procedure have some output variable (may be more than one) :
declare
var_in1 varchar2(10);
var_in2 varchar2(10);
var_out1 varchar2(10);
var_out2 varchar2(10);
Myprocedure(var_in1,var_in2,var_out1,var_out2);
print var_out1;
print var_out2;Nicolas. -

Why a function within a SELECT FROM DUAL is faster?
1)I have a SELECT with a function. Ex:
"SELECT DISTINCT function(...) FROM table"
2)I changed the SELECT and put the function inside a SUB-SELECT with FROM DUAL. Ex:
"SELECT DISTINCT (SELECT function(...) FROM DUAL) FROM table"
3)The second SELECT is faster than the first.
I discovered this problem on my tables and my functions. So I did a generic example for this forum with a common function and large table. My results:
Table has 2.196.058 records and the field is a VARCHAR2:
SELECT DISTINCT SUBSTR(field, 2) FROM Table -> Executed in 110 seconds
SELECT DISTINCT (SELECT SUBSTR(field, 2) FROM DUAL) FROM Table -> Executed in 39 seconds
Why "SELECT DISTINCT (SELECT function(...) FROM DUAL) FROM table" is faster than "SELECT DISTINCT function(...) FROM table"
thanks,
FernandoHi hoek,
I followed your informations and, sorry, I am more confused! I did an interesting example below.
1)I created a table:
CREATE TABLE T
name VARCHAR2(50)
); 2)I inserted 10 lines:
NAME
A
B
C
D
E
F
G
H
I
J 3)I created a function that returns the parameter concatenated with the current millisecond:
CREATE OR REPLACE FUNCTION f (param1 IN VARCHAR2) RETURN VARCHAR IS
BEGIN
return param1 || '-' || to_char(CURRENT_TIMESTAMP, 'FF');
END; 4)The query(A): SELECT f(name) AS col1, f(name) AS col2, f(name) AS col3 FROM t; gave me:

J-254495000 J-254523000 J-254551000The result generated new values too.
5)I changed the function and I put the DETERMINISTIC clause:
CREATE OR REPLACE FUNCTION f (param1 IN VARCHAR2) RETURN VARCHAR DETERMINISTIC IS
BEGIN
return param1 || '-' || to_char(CURRENT_TIMESTAMP, 'FF');
END; 6)I repeated the queries(A) and (B) and the result has generated different values. Then, with the DETERMINISTIC clause, the result has not changed
7)I changed the function and I put the RESULT_CACHE clause:
CREATE OR REPLACE FUNCTION f (param1 IN VARCHAR2) RETURN VARCHAR RESULT_CACHE IS
BEGIN
return param1 || '-' || to_char(CURRENT_TIMESTAMP, 'FF');
END;8)I repeated the query(A) and now, the result was different:

The to_date function doesn't work ?
Hello
I don't know why my to_date function doesn't work on my pc.
my statement is pretty complex so i just tried simple one
select to_date('10-Jan-2006','dd-mon-yyyy') from dual;
but even this one doesn't work it says it is invalid month
howcome?
is it because my Windows XP (not english version) doesn't recognise month Jan?
i tried it another place it worked
so is there any language pack / patch i need to install? ?
so does OS matters?
or how to fix this..please help meBy default SQL Developer picks up it's language settings up from (on Windows) the Regional and Language Options. You can see what it has set by querying the NLS_SESSION_PARAMETERS view.
Assuming you don't want to change to using DD-MM-YYYY formats for your months or change your regional settings on your PC, you need to tell SQL Developer which language you want, which you can do by adding the following lines to the file sqldeveloper\jdev\bin\sqldeveloper.conf:
AddVMOption -Duser.language=en

Select sysdate from dual (to custom format).
Dear all,
i like to SELECT SYSDATE FROM DUAL, and run this result in a query something like:
SELECT X, Y, Z FROM TABLENAME WHERE ACCESSDATE = (SELECT SYSDATE FROM DUAL);
The problem is that the value of ACCESSDATE is in an format like DD-MM-YYYY and that sysdate form dual is
DD-MON-YYYY.
How do i get sysdate into the format DD-MM-YYYY?
Thanks already,
Johan.Perhaps usefull for performance:
first of all: no subselect is not needed. sysdate can be used as an argument directly (all functions are).
secondly, if accessdate is of type 'date' and the table has a lot of rows, converting it to a char will bypass the index usage. Instead, if you are worrying about the time try this (the display format is of no concern here if the datatype is date):
SELECT X, Y, Z FROM TABLENAME WHERE ACCESSDATE >trunc(sysdate) and ACCESSDATE < trunc(sysdate+1);
if accessdate is of type 'varchar2' then this should be enough (and should remain using the indexes on accessdate):
SELECT X, Y, Z FROM TABLENAME WHERE ACCESSDATE = to_date(sysdate,DD-MM-YYYY);
Hope this helps,

TO_DATE function's weird feature
Hi Friends,
Is the following statement workable?
select to_date('09,06,16 12:12:59','yyyy-mm-dd hh24@mi,ss') from dual;
My own anwser is YES but the result is decided by NLS_DATE_FORMAT.
Have you any different opinions?Hi Dear Friends,
In my own experience, the result depends on nls parameter NLS_DATE_FORMAT and the second parameter in to_date(arg1,arg2) function. For example, if you update the nls parameter NLS_DATE_FORMAT to be "YYYY-MM-DD" and execute the following statement, what the result do you expect?
select to_date('09,06,16 12:12:59','yyyy/mm/dd hh24@mi,ss') from dual;and try the following one again:
select to_date('09.06.16 12:12:59','rrrr\mm\dd hh24@mi,ss') from dual;In my own understanding, the statement execute process is like this:
1. Execute to_date function and get the Date result. If to_date function does not provide the second argument, the nls parameter NLS_DATE_FORMAT will be used. It is the truth that the separator character does not matter in the date format.
2. Pass Date result to the tool such as sqlplus or sqldeveloper, to_char function is executed in background, the result will be printed to us. The format of to_char function is decided by nls parameter NLS_DATE_FORMAT. So, if you udpate nls parameter NLS_DATE_FORMAT to be 'rrrr\mm\dd hh24@mi,ss' in above examples, you will get the result with the same format - the separator is the same of that in nls parameter NLS_DATE_FORMAT. Just try it! :)
So, that's my own conclusion, if you have different views, please do not hesitate to share with me.

Dear All,
I need Output of the following query in the 'JANUARY' or 'JAN' i.e. 'MONTH' or 'MON' format. But following query is returning full date. Could any person help to get me output in MONTH or MON format but SQL should be using TO_DATE function.
TO_DATE(to_char(trunc(ORDERED_DATE),'MONTH'),'MONTH') order_date
Above query is failing to return desired output.
ThanksFor each DATE value, Oracle stores the following information: century, year, month, date, hour, minute, and second.
http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/sql_elements001.htm#sthref116
there are some conversion functions :

http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/functions201.htm#i79761
moreover, the human eye can only read character datatypes (not number or date datytypes) !
which means, whenever you do a select sysdate from dual there will be an implicit conversion
to character datatype to make it readable for you (according to nls_date_format) .
alter session set nls_date_format = 'DD.MM.YYYY' ;
select sysdate today from dual ;
TODAY
21.12.2008
alter session set nls_date_format = 'YYYY.MM.DD' ;
select sysdate today from dual ;
TODAY
2008.21.12So the same statement select sysdate today from dual ; will give different results on different systems,
just depending on some initial settings !
You ask why ? It's because you are using implicit conversion !!!

After seeing many questions on TO_DATE function,I think it will be better to post
this useful information on to_date function.please correct me if i am wrong
anywhere in the post.
TO_DATE :
SYNTAX:TO_DATE(i/pstring[,i/pstringfmt[,nlsparam]])Note:Apart from third party tools which have their own default settings,the output of to_date is in the format specified by NLS_DATE_FORMAT parameter in NLS_DATABASE_PARAMETERS view.
Note: The format that we are specifying in to_date function is the format of the i/p string
and not the format of the o/p date.
Ex:
SQL> select to_date('12-JAN-2008','DD-MON-YYYY') from dual;
TO_DATE('
12-JAN-08
SQL> select to_date('12-01-2008','DD-MM-YYYY') from dual;
TO_DATE('
12-JAN-08
SQL> select to_date('12/01/2008','DD/MM/YYYY') from dual;
TO_DATE('
01-DEC-08Q) So, for to_date we have to give the format of i/p string. But in some cases, even if i give a format other than the format of i/p string, I am getting the o/p.
Ex1. SELECT to_date('01.JAN.2008','DD-MON-YYYY') from dual;
Ex2. SELECT to_date('01/JAN/2008','DD-MON-YYYY') from dual;
Ex3. SELECT to_date('01-JAN-2008','DD-MM-YYYY') from dual;
Ex4. SELECT to_date('01-JANUARY-2008','DD-MM-YYYY') from dual;A)The answer for 1 and 2 is, Oracle will not match separators(./-) in the string and format mask.
It only matches corresponding values. space can be a separators in the format mask.
Ex:select to_date('2008-01-01','YYYY MM DD') from dualIn case if the i/p string does not match with the format mask, Oracle substitutes the format mask element with its alternatives and even after this, if it cannot convert the i/p string to the given format mask, then it throws an error.
Alternate Format masks Table:
Format Mask Alternate Format Mask
Element allowed in i/p String
MM MON,MONTH
MON MONTH
MONTH MON
YY YYYY
RR RRRR
RR RRIn Ex3 and Ex4, we have MM in the format mask and MON (JAN), MONTH (JANUARY) in i/p string.
According to the above table, Oracle makes an implicit substitution of alternate format mask MON or MONTH
and hence it does not give an error. But this statement SELECT TO_DATE (’01-01-2008’,’DD-MON-YYYY’)
FROM DUAL will always error out because according to the above given table, if you have ‘MON’ in the format mask, then only MON (JAN) or MONTH (JANUARY) is allowed in the i/p string.
Q) Since format mask is optional, if i do not give any format mask, then How Oracle will convert the given string to a date?
A) If we do not specify any format mask, then Oracle assumes that the string is in default date format and tries to convert it into a date.If the i/p string is not in the default date format, then it will give an error.
Ex: Assume that the default date format is ‘DD-MON-RR’.
Now if you execute a statement like, SELECT to_date(’01-01-2009’) from dual, it will error out since it is not in the default format and also not convertable by implicit substitution according to the implicit substitution table.
Q)If i have time fields in the format mask and if i did not give them in the i/p string like select to_date('10-JAN-2008','DD-MON-YYYY HH24:MI:SS') from dual ,will it error out?
A)You can omit the time fields in the i/p string, beause if nothing is provided then Oracle will implicitly take time as 00:00:00 and hence it will not give an error.
Q)If i give some thing like select to_date('2008-05-01','DD-MM-YYYY') from dual, it errors out but if i give select to_date('2008-05','DD-MM-YYYY') from dual, then there is no problem. what is the reason for it?
A)On seeing the format mask DD-MM-YYYY, it takes first 2 digits (20) as DD ,the next 2 digits(08) as month, the next 2 digits for year(05).After coming this far, still there is some portion(01) of the string that is not matched and hence it throws an error and once we remove ‘01’ as given in the question, it works absolutely fine.

Q)Some people have a misconception that a statement like to_date('01-01-2008','DD-MM-YYYY') will always convert the string '01-01-2008' into a date with the given format 'DD-MM-YYYY'.
A)It might or might not .It all depends on value of NLS_DATE_FORMAT parameter in NLS_DATABASE_PARAMETERS view.Well,if the value of the parameter is 'DD-MM-YYYY'
then the answer is 'YES' else the answer is 'NO'.The Answer should simply be "It won't". with the reason being that "the DATE datatype does not have a display format, only an internal format which is consistent regardless of how you want to display it. The format specified in the TO_DATE function relates to the format of the input string; how the date returned from that function is _displayed_ is completely independant of, and unrelated to, the TO_DATE function." -
How to calculate a string (select '1 + 1' from dual;)
I have this system that gives me data (roughly a gig per hour) in the format:
Time_idle
13h 56m
56m 23s
24h 23m
4h 3m
4m 3s
I have to translate it into date, or desimal hour so I can use it in calculations and SQL.
How can I do this?
I have tried the following:
select RTRIM(REPLACE(REPLACE(REPLACE(REPLACE(time_idle,'h',''),'m','/60'),'s','/3600'),' ','+'),'+') from thedate where prosess = 1;
and I then get:
result:
10+54/60
14+12/60
54/60+1/3600
which is correct, if I could get Oracle to calculate the number sum instead of just providing me with the string value. How do I make Oracle calculate the value of the string?
Or how can I use to_date function to translate the text into a date?
Anyone know?

Calling the function from SQL query
Hi,
I am trying to run the below statement,

Thanks in advance.If the function is performing DDL, commit or rollback inside it then you will not be able to call it from an SQL statement.
Either change the function so it doesn't perform DDL, commit or rollback, or use a different means to obtain the information you want (assuming you can't change the function) -
Parallel run of the same function from multiple jobs
Hello, everyone!
I have a function which accepts a date range, reads invoices from a partitioned by date table and writes output to a partitioned by invoice table. Each invoice can have records only with one date, so both tables may have one invoice only in one partition, i.e. partitions do not overlap. Function commits after processing each date. The whole process was running about 6 hrs with 46 million records in source table.
We are expecting source table to grow over 150 million rows, so we decided to split it into 3 parallel jobs and each job will process 1/3 of dates, and, as a result, 1/3 of invoices.
So, we call this function from 3 concurrent UNIX jobs and each job passes its own range of dates.
What we noticed, is that even if we run 3 jobs concurrently, they do not run this way! When 1st job ends after 2 hrs of run, the number of commited rows in the target table is equal to the number of rows inserted by this job. When 2nd job ends after 4 hrs of run, the number of rows in the target table is equal the summary of two jobs. And the 3rd job ends only after 6 hrs.
So, instead of improving a process by splitting it into 3 parallel jobs we ended up having 3 jobs instead of one with the same 6 hrs until target table is loaded.
My question is - How to make it work? It looks like Oracle 11g is smart enough to recognize, that all 3 jobs are calling the same function and execute this function only once at the time. I.e. it looks like only one copy of the function is loaded into the memory at the same even if it called by 3 different sessions.
The function itself has a very complicated logic, does a lot of verifications by joining to another tables and we do not want to maintain 3 copies of the same code under different names. And beside this, the plan is that if with 150 mln rows we will have a performance problem, then split it to more concurrent jobs, for example 6 or 8 jobs. Obviously we do not want to maintain so many copies of the same code by copying this function into another names.
I was monitoring jobs by quering V$SESSION and V$SQLAREA ROWS_PROCESSED and EXECUTIONS and I can see, that each job has its own set of SID's (i.e. runs up to 8 parallel processes), but number of commited rows is always eqal to the number of rows from the 1st job, then 2nd+1st, etc. So, it looks like all processes of 2nd and 3rd jobs are waiting until 1st one is done.
Any ideas?OK, this is my SQL and results (some output columns are ommited as irrelevant)
