I have a report that has two parameters, PM_DATE and PM_STOCK_ID. It's LOV query is
SELECT DISTINCT ID FROM STOCK_COUNT
I want to filter the parameter PM_STOCK_ID based on the date which user specifies in date parameter. In the where clause of LOV I tried using:
SELECT DISTINCT ID FROM STOCK_COUNT
WHERE TRUNC (SCHEDULE_DATE) = NVL (:PM_DATE, SCHEDULE_DATE)
but this didn't work.
I've also tried with a range using two parameters, P_SDATE (Start Date) and P_EDATE (End Date):
SELECT distinct id FROM STOCK_COUNT
WHERE
(TRUNC(SCHEDULE_DATE)) BETWEEN NVL(:P_SDATE, TRUNC(SCHEDULE_DATE)) AND NVL(:P_EDATE, TRUNC(SCHEDULE_DATE))
which gets error:
Parameter name: P_STOCK_ID Unparseable date: ""
How should I be doing this?
By just specifying the string :PM_DATE without a to_date function around it, you are getting implicit type conversion which is likely the root cause of the difficulty.

I need to restrict a query with a
SELECT ... FROM ...
WHERE my_date=(RESULT FROM A SELECT)
... ;
in order to achieve that I am using as result of the select a timestamp (if I instead use a datetime I get nothing from my select probably because the format I am using trims the datetime at the second).
Sadly this is not working because these kindo of queries:
select DISTINCT TO_DATE(TO_TIMESTAMP(TO_DATE('25-10-2017 00:00', 'dd-MM-yyyy HH24:MI'))) from DUAL;
return an
ORA-01830: date format picture ends before converting entire input string
how to deal with timestamp to date conversion?
If you want to just compare and check only he dates use trunc on both LHS and RHS.
SELECT ... FROM ...
WHERE trunc(my_date)=(select trunc(RESULT) FROM A)
... ;
This will just compare the dates by truncating the timestamp values
You can use the combination of "TRUNC" and "IN" keywords in your query to achieve what you are expecting. Please check the below query sample as a reference.
SELECT * FROM customer WHERE TRUNC(last_update_dt) IN (select DISTINCT (TRUNC(last_update_dt)) from ... )

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 am writing an SQL query where the query should first search the first value, and only if this value is missing the query should search for the second value.
I have two tables. One of these tables contains the modification date (this is not always filled and can be null) and a creation date which is always filled.
Now what I want is that the query first looks in the table with the modification date and only if it is null looks at the table with the creation date.
Example of the query:
Select *
from all_articles
where to_char(modification_date, 'YYYYMMDD') = to_char(sysdate, 'YYYYMMDD')-1
-- if this is an empty record then
to_char(creation_date, 'YYYYMMDD') = to_char(sysdate, 'YYYYMMDD')-1
Can anyone help me with this query?
Almost all the major RDBMS' available have in built functions to handle such a situation.
The Oracle DB has NVL function which works as follows:
NVL(Modified_dt, Create_dt);
The above will return Modified_dt column data by default. However, if that isn't available, it will return Create_dt.

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.
