Number to HH24:MI:SS

Hi,
I have a database field which holds the number of seconds an event has been ongoing. I need to display that in hours, minutes and seconds but have no idea how to do it.
Have looked on the internet for solutions but have found very little.
Thanks for any help
Simon

Using an interval is more robust than relying on the elapsed time being less than 1 day, however, wrapping it with a to_char does give a somewhat unsavory output:
select to_char(NUMTODSINTERVAL(198393,'second')) dts from dual
DTS
+000000002 07:06:33.000000000
1 rows selectedI'm not sure if the to_char function will respect any format models when used with an interval (none of the ones I tried worked), however, you can get around that by formatting it yourself:
with t1 as (select NUMTODSINTERVAL(198393,'second') dts from dual)
select extract(day from dts)|| ' Days, ' ||
       extract(hour from dts)|| ' hours ' ||
       extract(minute from dts)|| ' minutes and ' ||
       extract(second from dts)|| ' seconds' tada
from t1
TADA
2 Days, 7 hours 6 minutes and 33 seconds

Convert Number to HH24:MI:SS

Hi,
I am using oracle database version 11.2.1 and would like to convert a number in minutes to date format HH24:MI:SS
I am using the following syntax but this does not include seconds, returns format HH24:MI
select FLOOR (165.44 / 60) || ':' || TO_CHAR (MOD (165.44, 60), 'FM00')
from dual
Is it possible to add seconds HH24:MI:SS?

select
nInt,
extract(hour from nInt) + extract(day from nInt)*24
||':'||
extract(minute from nInt)
||':'||
round(extract(second from nInt))
as result
from (
select
numtodsinterval(165.44, 'MINUTE')
) nInt
from dual
union all
select
numtodsinterval(165.444, 'MINUTE')
) nInt
from dual
union all
select
numtodsinterval(1540.30, 'MINUTE')
) nInt
from dual
NINT RESULT

How to come up with a magic number for any table that returns more than 32KB?

I am in a unique situation where in I am trying to retrieve values from multiple tables and publish them as XML output. The problem is based on the condition a few tables could retrieve data more than 32KB and a few less than 32KB. Less than 32KB is not an issue as XML generation is smooth. The minute it reaches greater than 32KB it generates a run time error. Just wondering if there is any way to ensure that the minute the query's results is greater than 32 kb, it should break say - if the results is 35KB, then I should break that result into 32 KB and 3kb; once done then pass this data to be published as an XML output. This is again not just for one table, but all the tables that are called in the function.
Is there any way?? I am unable to get any ideas nor have I done anything so complex from production support stand point. Would appreciate if someone can guide me on this.
The way it is, is as follows:
I have a table called ctn_pub_cntl
CREATE TABLE CTNAPP.ctn_pub_cntl

                     || ' AND rownum < 16'
The minute I comment
|| ' AND rownum < 16' ;
, it throws an error because this query returns around 600 rows and all of those rows need to be published as XML and the tragedy is that there is a C program in between as well i.e. C will call my packged functions and then will do all the processing. Once this is done will pass the results back to C program. So obviously C does not recognise CLOB and somewhere in the process I have to convert the CLOB to VARCHAR or instead of CLOB I have to use VARCHAR array as a return type. This is my challenge.
Anyone that can help me to find out the required magic number and also a brief know how, I would appreciate that. Many thanks in advance.

Not sure I understand which part is failing.
Is it the C program calling your packaged function? Or does the error occur in the PL/SQL code, in which case you should be able to pinpoint where it's wrong?
A few comments :
1) Using DOM to build XML out of relational data? What for? Use SQL/XML functions.
2) Giving sample data is usually great, but it's not useful here since we can't run your code. We're missing the base tables.
3) This is wrong :
vStrSqlQuery := 'SELECT * FROM ' || vTblName                     || ' WHERE record_update_tms <= TO_DATE(''' || TO_CHAR(vLastPubTms, 'MM/DD/YYYY HH24:MI:SS') || ''', ''MM/DD/YYYY HH24:MI:SS'') ' ;
A bind variable should be used here for the date.
4) This is wrong :
elmt_value := xmldom.createTextNode (doc, l_clob(1));
createTextNode does not support CLOB so it will fail as soon as the CLOB you're trying to pass exceeds 32k.
Maybe that's the problem you're referring to?
5) This is most wrong :
     l_clob(1):=REPLACE(l_clob(1),'<?xml version="1.0"?>', NULL);
     l_clob(1):=REPLACE(l_clob(1),'<', '<');
     l_clob(1):=REPLACE(l_clob(1),'>', '>');
I understand what you're trying to do but it's not the correct way.
You're trying to convert a text() node representing XML in escaped form back to XML content.
The problem is that there are other things to take care of besides just '<' and '>'.
If you want to insert an XML node into an existing document, treat that as an XML node, not as a string.
Anyway,
Anyone that can help me to find out the required magic number
That would be a bad idea. Fix what needs to be fixed.
And please clearly state which part is failing : the C program or the PL/SQL code?
I'd vote for PL/SQL, as pointed out in [4].

Function to convert string to number

Hi there,
I wrote a function which converted a hor minute component of a date to a number. Now I need to do the same with a string (because the hours could be more then 23:95). Anyway here is my function. How can I rewrite it so it will accept a string as in parameter. Somwhow I can not work it out. Thanks a lot.
Chris
function calculate_hours_project(in_hours in DATE)
RETURN number
AS
hrs CHAR(2);
mins CHAR(2);
     BEGIN
          hrs := to_char(in_day, 'HH24');
          mins := to_char(in_day, 'MI');
          if hrs is not null and mins is not null then
          RETURN to_number(hrs + (mins/60));
          else
          RETURN 0;
          end if;

Wouldn't it just be something like this?

How can I determine what is the minimum SCN number I need to restore up to.

Say if I have a full database backup, I know I have file inconsistency, but I want to know what is the minimum time or SCN number a need to roll forward to in order to be able to open the database?
For example: I do a database restore.
restore database ;
RMAN> sql 'alter database open read only';
sql statement: alter database open read only

I need need to apply archive log files. All references I find for ORA-00194 state the solution is to "apply more logs until the file is consistent " But "HOW MANY LOGS", or more apporaite up to what time or SCN? How does one determine what TIME or SCN is required to get all file consistent?

I've discover I need to apply archive logs until this query reports all datafiles as FUZZY=NO , but this only works by guessing at some time periord to roll forward to, then checking the FUZZY column, and try again. Is there a way to know, I have to roll forward to a specific SNC in order for all my datafiles to be consistent?
select file#

     , checkpoint_change#
     , checkpoint_time
     , FUZZY
     , RECOVER
,LAST_DEALLOC_SCN
from v$datafile_header
order by checkpoint_time
Thanks,
Jason

The minimum point in time is the time when the last backup piece for datafiles in that backup was completed.
Your alert.log should show the redo log sequence number at that time.
You can query V$ARCHIVED_LOG and get the FIRST_CHANGE# of the first archivedlog generated after that backup piece completed.
A
LIST BACKUP;in RMAN should also show you the SCNs at the time of the backups.
You can also query SCN_TO_TIMESTAMP -- eg
select timestamp_to_scn(to_timestamp('15-MAR-09 09:24:01','DD-MON-RR HH24:MI:SS')) from dual;will return an approximation of the SCN.

Number of concurrent users

how can I find the number of concurrent users in oracle 10g;
thank you

You mean ACTIVE users ??
Use following script :

select username, count(*) from v$session where status = 'ACTIVE'
group by username;
column spid format a5
column sid format 9999

column status format a10
column module format a25
select a.sid, a.serial#, b.spid,
--a.process,
a.username,
to_char(a.logon_time,'DD-MM HH24:MI:SS') LogonDate, a.osuser, a.machine, a.status, a.module
from v$session a, v$process b where a.paddr = b.addr

select start_date - end_date from dual;
How do I get HH:MM results ? Thanks

If greater than 24 hours you'll need to calculate the hours and minutes as numbers individually. (You can then display them in whatever format you choose)

Conversion from date to number & display a date in a textfield

I Have 2 issues
The first one:
I need to extract the hour from a date variable.
This is the code I already have:
NUM_TOT := NUM_TEL + to_number('PROGRAMMINGS1.PRG_START','hh24');
NUM_TOT & NUM_TEL are number variables,
PROGRAMMINGS1.PRG_START is a Textfiel with a dateformat. There can only be an houre like 24:59:00 entered.
So in this example I just want the houre and convert it to a number.
The second:
I want to make a date from a few numbers & then display it in a texfield.
This is the code I already have:
VAR_DATE := NUM_TEL || ':' || NUM_LENGTH || ':00';
:PROGRAMMINGS.PRG_END := to_date(VAR_DATE,'hh24:mi:ss');
Between the 2 lines of code i places a message(VAR_DATE) for testing.
When the program display VAR_DATE then i can see the good date at the bottom of the screen.
But when I place my variable in the textfield it looks like: 00:00:00. What am I doing wrong?
Who can help me.
With regards

Problem: During the conversion (both implicit and explicit conversion with a format mask) I lose the "00" hours and "00" minutes and receive something like this: "10-JAN-13 *12*.00.00.000000000 AM".I don't think you are necessarily losing any information whatsoever. It's probably more of a function of your NLS_TIMESTAMP_FORMAT and NLS_DATE_FORMAT. For example your NLS_DATE_FORMAT could be setup by default for a HH24 (24 hour time) which would report midnight as "00" hours. However, it looks like your NLS_TIMESTAMP_FORMAT is setup with a "HH" format with a meridian indicator which means 12 hours time.
Your comparisons should be using date/timestamp data types anyways so as long as the input value is converted properly into a date type this shouldn't matter anyways.
You can see what is actually stored by using the DUMP function:
SQL> SELECT DUMP(TO_TIMESTAMP(TO_CHAR(TRUNC(SYSDATE,'DD'),'MM/DD/YYYY HH:MI:SS AM'))) AS TSTAMP
2 ,       DUMP(TRUNC(SYSDATE,'DD')) AS DT
3 FROM DUAL
4 /
TSTAMP                                                                      DT
Typ=187 Len=20: 218,7,1,13,0,0,0,0,0,0,0,0,0,0,3,0,0,0,0,0                  Typ=13 Len=8: 218,7,1,13,0,0,0,0As you can see the TSTAMP and DT store nearly the same values (218,7,1,13), but the TSTAMP has more precision because of fractional seconds.
HTH!

Check which table has no column with specific name over number of tables

Hello,
Withing my schema I have 66 tables, all of them have column last_update_date. Though not all have the column program_update_date. The problem is I want to go through all the tables and know which tables does not have the program_update_date column. It is to be noted that if the table does not have the program_update_date column query 2 will be used instead of query 1.
query1:
select last_extract_date,
to_char(min(greatest(nvl(*last_update_date*,'01-Jan-10'),nvl(*program_update_date*,'01-Jan-10'))),'DD-MON-YY HH24:MI:SS') mi,
to_char(max(greatest(nvl(*last_update_date*,'01-Jan-10'),nvl(*program_update_date*,'01-Jan-10'))),'DD-MON-YY HH24:MI:SS') ma
from table_names
group by last_extract_date
order by last_extract_date desc;
query2:
select last_extract_date,
     to_char(min(nvl(last_update_date,'01-Jan-10')),'DD-MON-YY HH24:MI:SS') mi,
     to_char(max(nvl(last_update_date,'01-Jan-10')),'DD-MON-YY HH24:MI:SS') ma
     from mispa_events
     group by last_extract_date
     order by last_extract_date desc ;
Please find the PLSQL code that should be used:
Declare
cursor C_1 is
select unique table_name from user_tables; table_names varchar2(240); Begin Open C_1; Loop Fetch C_1 into table_names; EXIT WHEN C_1%NOTFOUND;
EXECUTE IMMEDIATE('select last_extract_date,
to_char(min(greatest(nvl(last_update_date,''01-Jan-10''),nvl(program_update_date,''01-Jan-10''))),''DD-MON-YY HH24:MI:SS'') mi,
to_char(max(greatest(nvl(last_update_date,''01-Jan-10''),nvl(program_update_date,''01-Jan-10''))),''DD-MON-YY HH24:MI:SS'') ma
from ' || table_names ||'
group by last_extract_date
order by last_extract_date desc');
End Loop;
Close C_1;
COMMIT;
End;
Please help.
Thanks in advance.

Hi all,
Below is my stored proc and it has a input parameter 'c_count_or_perc' . I have passed value to this parameter as in the if block.
But I got the error as "wrong number or types of argumnet in a call to ' .
I really dont know how to pass input value to this parameter .
Could anyone please help?

Hi,
Thx for the reply.
As the store proc is inside the package and its invoked in visual studio.
I used to compile the pkg in SQL plus and it throws the error as ' wrong number or types of argument in a call to the stored proc 'edr_rpt_gen_error_by_hour'
As I'm new to pl/sql programming , i really dont know how to pass value to the input parameter.

Procedure with variable number of columns

Hi, I have a procedure that looks like this:
PROCEDURE PROC(p_cursor OUT sys_refcursor)
And in the procedure, I build up QUERY dynamically and the number of columns varies at runtime.
At the end I do
OPEN p_cursor for QUERY
Then to call this, I'm doing
call PROC(?)
My question is, how would I go about running the query from this procedure, then adding rows or modifying the existing results, then returning the modified data?
What I want to do is add a new row based on some condition, so I still need to return a variable number of columns, but I need to modify the results before I return them.
Is there any way of doing this? I need to do some calculations on the columns (the variable columns), create a new row, insert into result set, and return this new result set.

A sys_refcursor is ideally suited to pass back to a front end gui like .NET or Java which can then use that cursor to retrieve the data.
In PL/SQL there is no point in using a sys_refcursor unless you know, at design/compile time what the returned columns are going to be.
If the resultant columns are dynamic, then you have no choice but to use the DBMS_SQL package, where you can parse and execute any SQL statement you like and then use the DBMS_SQL package to describe what the resultant columns are and how many there are. From that you can reference the columns by position rather than by name.
e.g.
CREATE OR REPLACE PROCEDURE run_query(p_sql IN VARCHAR2) IS
v_v_val     VARCHAR2(4000);
v_n_val     NUMBER;
v_d_val     DATE;
v_ret       NUMBER;
c           NUMBER;
d           NUMBER;
col_cnt     INTEGER;
f           BOOLEAN;
rec_tab     DBMS_SQL.DESC_TAB;
col_num     NUMBER;
v_rowcount NUMBER := 0;
BEGIN

SQL>In 11g, you can create a sys_refcursor and then the DBMS_SQL package allows you to convert that refcursor into a DBMS_SQL cursor so that you can get the description of the results and do the same. This isn't available prior to 11g though.
However_ before any of that, you should really ask yourself if there is a real need to dynamically be creating queries. There is rarely any real need to do that and if you're finding it's common in your application then this is often a sign of poor design or poorly defined business requirements (leaving the technical side to try and be "flexible" and hence leading to unmaintainable code etc.).

Number of records in 30 minutes interval.

Hi All,
I am trying to find number of records in 30 minutes of interval. Being said that, i am trying to find out number of records i am getting in 30 minutes. In my table i have a column called "Last_UPDATE_DATE" with date and time. Can somebody help me, possible way to achive. I tried to think through on how to get, but not getting required information.

And this is yet another solution:
with timeranges as
select trunc(sysdate)+(level-1)*(30/24/60) starttime
     , trunc(sysdate)+(level)*(30/24/60) endtime
from dual connect by level <= (24*2)
select TO_CHAR(b.starttime, 'MM/DD/YYYY HH24:MI:SS') starttime
    , TO_CHAR(b.endtime, 'MM/DD/YYYY HH24:MI:SS') endtime
    , (select count(*)
         from abc a
        where a.last_update_date > b.starttime
          and a.last_update_date <= b.endtime
      ) cnt
from timeranges b
group by b.starttime, b.endtime
order by b.starttime;
STARTTIME           ENDTIME                    CNT

I'm having problems inserting a value from a date picker field (DD-MON-YYYY HH MI )
i'm submitting this value to a packaged procedure that accepts this field as VARCHAR2 .
on the insert, i do a to_date( P_DATE, 'DD-MON-YYYY HH:MI PM' )
and i get the numeric conversion error.
If I change the to_date on the procedure side, I get the :could not read the end of the format mask - which I've found threads about on this site.
I've tried using HH24 and different formats, but I get one of the two above errors on the insert.
If I don't fill in the datepicker field at all, it works fine.
help is appreciated !

Using column number inplace of column name in SQL Select statement

Is there a way to run sql select statements with column numbers in
place of column names?
Current SQL
select AddressId,Name,City from AddressIs this possible
select 1,2,5 from AddressThanks in Advance

user10962462 wrote:
well, ok, it's not possible with SQL, but how about PL/SQL?As mentioned, using DBMS_SQL you can only really use positional notation... and you can also use those positions to get the other information such as what the column is called, what it's datatype is etc.

Could anyone help in writing a query to retrieve the number of transactions done in every 1 hour for last month.
Case:
I/P
Cases Timestamp1

etc
Any help really appreciated

We can do this using analytical functions
Following is what I did:
create table timestamp1 (ts date)
select *from timestamp1
30/10/2008 15:41:13
30/10/2008 15:41:05
30/10/2008 15:40:03
30/10/2008 14:58:26
30/10/2008 14:29:45
30/10/2008 13:17:48
30/10/2008 08:29:50
30/10/2008 06:05:51
30/10/2008 03:41:52
30/10/2008 02:29:54
select distinct to_char(ts,'hh24') frmhrs,
to_char(ts,'hh24')+1 tohrs, count(ts) OVER (order by to_number(to_char(ts,'hh24')) RANGE (1/24) PRECEDING )
from timestamp1
where trunc(ts)=trunc(sysdate) -- I added this just to make sure I get for today's data
order by frmhrs
FRMHRS     TOHRS     CNT
02     3     1
03     4     1
06     7     1
08     9     1
13     14     1
14     15     2
15     16     3
You can customizeas per ur need.
