[Correction]
I am trying fetch query result in a xls using column headers in oracle
Below is the query
select
'Student Name'
'Joining Date'
from dual
union all
select
student_name
to_char(joining_date,'MM/DD/YYYY')
from student_details
The only thing being that once I get this in a xlsfile , I am not able to sort the data using joining_date since it is converted to varchar/char.
I need a solution wherein I am able to include the headers and retain the data type (date,number) in the final xls result.(I can format cells in excel to date/number but I wish to get it done through database query itself)
Please help!
Extract data as Oracle literals:
1) numbers - 123.354
2) strings - q'{This is a string}' / 'This is another string'
3) dates - DATE'2016-04-31'
4) dates with time/timestamps - TIMESTAMP'2016-04-31 11:13:00'/TIMESTAMP'2016-04-31 11:13:00.000000'

Hi I am having issue when extracting fields from CLOB data. For one record I am not getting desired output.
The record is as below:
{1:F014243107336}{2:O2021216200422XXX24563}{3:{108:O2020}{121:2c02a452-5}{433:HIT}}{4:
:4A:SEC:20200901
:4B:FC5253
:4C:20042000,
:4D:XXXXXXX
:4E:RXX
:4F:RXXXX
-}{5:{CHK:87D1003B01F7}{TNG:}}{S:{SAC:}{COP:S}}<APSECSIGN>FS3sfasdfg!==</APSECSIGN>?
I want to extract data from tag :4A: into REF_NUMBER.
I am using below SQL to get the data.
NVL(TRIM(TRANSLATE(REGEXP_REPLACE(REGEXP_SUBSTR(dbms_lob.substr(CLOB, 4000, 1 ), ':4A.?:[^:]+(:|-\})'), ':20.?:([^:]+)(:|-\})', '\1'),CHR(10)||CHR(13), ' ')),' ') AS REF_NUMBER
the output I am getting is "SEC". However I want to see output as SEC:20200901.
Can any one suggest what I am missing in my query or provide me correct query.
A general suggestion. Why don't you have your data stored as JSON ? Because, JSON related functions are very fast when compared to others. And then your problem becomes quite easy.
However to answer your question:
with inputs (str) as
(
select to_clob(q'<
{1:F014243107336}{2:O2021216200422XXX24563}{3:{108:O2020}{121:2c02a452-5}{433:HIT}}{4:
:4A:SEC:20200901
:4B:FC5253
:4C:20042000,
:4D:XXXXXXX
:4E:RXX
:4F:RXXXX
-}{5:{CHK:87D1003B01F7}{TNG:}}{S:{SAC:}{COP:S}}<APSECSIGN>FS3sfasdfg!==</APSECSIGN>?
>') from dual
)
select str, regexp_substr(str,'SEC:\d+',1,1,'n') as val
from inputs;
Output:
Updated
If you know the date is always going to be 8 digits after the :4A: tag, you can use REGEXP_SUBSTR to get the value you need. Combining it with DBMS_LOB.SUBSTR removes the tag and converts it to a string.
SELECT DBMS_LOB.SUBSTR ((REGEXP_SUBSTR (clob_val, ':4A:.*\d{8}')), 4000, 5)
FROM (SELECT EMPTY_CLOB ()
|| '{1:F014243107336}{2:O2021216200422XXX24563}{3:{108:O2020}{121:2c02a452-5}{433:HIT}}{4:

Your current plsql code segment :
XMLFOREST(Xmlelement("RC",REGION_CODE) AS RC,Xmlelement("TCPCODE",MODE_OF_TRANSPORT_CODE) AS TCPCODE) AS "item")
And as we have used aliases in here, we are getting multiple tags - One for alias, and one for the first parameter of XMLELEMENT function.
Now, since you just want an element - item, with two tags - RC (holding data of REGION_CODE field) and TCPCODE (holding data of MODE_OF_TRANSPORT_CODE field),
in my opinion, this should suffice your requirement:
Xmlelement("item", XMLFOREST(REGION_CODE "RC", MODE_OF_TRANSPORT_CODE "TCPCODE")
~Kuntal
with data(rc, tcpcode) as (select 'ads', 22 from dual)
select xmlelement("item", xmlforest(rc, tcpcode)) from data;

I have a date table in my db in Oracle. When I run a query I get the date format as '01-05-2015' but when I run a similar query in BIRT, I get the date format as '01-MAY-2015 12:00 AM'. How can I get the date format in dd/mm/yyy by keeping the data type of date field as date.
here is sample of my database.
EQ_DT
05-07-2015
06-06-2015
15-02-2015
19-09-2015
28-12-2015
also my query is :
select to_date(to_char(to_date(enquiry_dt,'DD/MM/YYYY'),'DD/MM/YY'),'DD/MM/YY') as q from xxcus.XXACL_SALES_ENQ_DATAMART where to_date(to_char(to_date(enquiry_dt,'DD/MM/YY'),'DD/MM/YY'),'DD/MM/YY')>'21-06-2012' order by q
I am getting error of NOT A VALID Month also
If enquiry_dt is already a date column, why are you trying to convert it to date (and then to char and to date again)?
SELECT to_char(enquiry_dt, 'DD/MM/YYYY') AS q
FROM xxcus.xxacl_sales_enq_datamart
WHERE enquiry_dt > to_date('21-06-2012', 'dd-mm-yyyy')
ORDER BY enquiry_dt
In birt, where you place the field on the report, set the field type to date. Then in properties for that field , go to format date time, and finally specify the date formatting you want for that field .
I prefer to always use pass date parameters as strings to BIRT, using a known date format. This is for report parameters as well as for DataSet parameters.
Then, inside the query, I convert to date like this:
with params as
( select to_date(pi_start_date_str, 'DD.MM.YYYY') as start_date_incl,
to_date(pi_end_date_str, 'DD.MM.YYYY') + 1 as end_date_excl
from dual
)
select whatever
from my_table, params
where ( my_table.event_date >= params.start_date_incl
and
my_table.end_date < params.start_date_excl
)
This works independent of the time of day.
This way, e.g. to select all events for january 2016, I could pass the query parameters '01.01.2016' and '31.01.2016' (I'm using german date format here).
I have a birt dataset for a db2 query. My query works fine without parameters with the following query...
with params as (SELECT '2014-02-16' enddate,'1' locationid FROM sysibm.sysdummy1)
select
t.registerid
from (
select
...
FROM params, mytable sos
WHERE sos.locationid=params.locationid
AND sos.repositorytype ='xxx'
AND sos.repositoryaccountability='xxx'
AND sos.terminalid='xxx'
AND DATE(sos.balanceDate) between date(params.enddate)-6 DAY and date(params.enddate)
GROUP BY sos.terminalid,sos.balancedate,params.enddate) t
GROUP BY
t.registerid
WITH UR
But when I change the top line to ...
with params as (SELECT ? enddate,? locationid FROM sysibm.sysdummy1)
And make the two input paramters of string datatype I get db2 errors sqlcode -418. But i know that it is not my querty because my query works.
What is the right way for me to set up the parameters so there is no error?
thanks
I'm not familiar with DB2 programming, but on Oracle the ? works anywhere in the query.
Have you looked at http://publib.boulder.ibm.com/infocenter/dzichelp/v2r2/index.jsp?topic=%2Fcom.ibm.db2z9.doc.codes%2Fsrc%2Ftpc%2Fn418.htm?
Seems that on DB2 it's a bit more complicated and you should use "typed parameter markers".
The doc says:
Typed parameter marker
A parameter marker that is specified with its target data type. A typed parameter marker has the general form:
CAST(? AS data-type)
This invocation of a CAST specification is a "promise" that the data type of the parameter at run time will be of the data type that is specified or some data type that is assignable to the specified data type.
Apart from that, always assure that your date strings are in the format that the DB expects, and use explicit format masks in the date function, like this:
with params as (
SELECT cast (? as varchar(10)) enddate,
cast (? as varchar2(80)) locationid
FROM sysibm.sysdummy1
)
select
...
from params, ...
where ...
AND DATE(sos.balanceDate) between date(XXX(params.enddate))-6 DAY and date(XXX(params.enddate))
...
Unfortunately I cannot tell you how the XXX function should look on DB2.
On Oracle, an example would be
to_date('2014-02-18', 'YYYY-MM-DD')
On DB2, see Converting a string to a date in DB2
In addition to hvb answer, i see two options:
Option 1 you could use a DB2 stored procedure instead of a plain SQL query. Thus there won't be these limitations you face to, due to JDBC query parameters.
Option 2, we should be able to remove the first line of the query "with params as" and replace it with question marks within the query:
select
t.registerid
from (
select
sos.terminalid,sos.balancedate,max(sos.balanceDate) as maxdate
FROM params, mytable sos
WHERE sos.locationid=?
AND sos.repositorytype ='xxx'
AND sos.repositoryaccountability='xxx'
AND sos.terminalid='xxx'
AND DATE(sos.balanceDate) between date(?)-6 DAY and date(?)
GROUP BY sos.terminalid,sos.balancedate) t
GROUP BY
t.registerid
A minor drawback is, this time we need to declare 3 dataset parameters in BIRT instead of 2. More nasty, i removed params.endDate from "group by" and replaced it with "max(sos.balanceDate)" in select clause. This is very near but not strictly equivalent. If this is not acceptable in your context, a stored procedure might be the best option.
Using SSRS with an Oracle Database. I need to prompt the user when running the report to enter a date for report. What is the best way to add in the parameter in my SSRS Report. Having problem finding the right date format. under the "Report Parameter" menu, I have setup the Report Parameters using the DateTime Datatype.
Keep getting this error "ORA-01843: Not a Valid Month"
Thank you for your help.

You use CAST(a.S_Date AS DATE) in your query, where a.S_Date is a VARCHAR: To_CHAR(ITH_F.Start_Time, 'MM/DD/YYYY'). If your session date parameter NLS_DATE_FORMAT is different from 'MM/DD/YYYY', this will result in a format error (in your case I suspect your NLS_DATE_FORMAT is something like DD-MON-YYYY, resulting in a "month" error).
A few options:
don't use TO_CHAR in the inner query (always try to keep the date format for internal calculations, use TO_CHAR only where it belongs -- in the GUI). If you only want the date portion, use TRUNC.
use TO_DATE instead of CAST in the outer query: to_date(a.S_Date, 'MM/DD/YYYY'), this is obviously tedious: you cast a date to a varchar that is later transformed to a date.
