I have table 'PORT_DTLS' with following fields: TN, Status_id, Req_Start_Time. Req_Start_Time has the time in this below format '8/12/2017 2:22:14.490361 PM'.
I have tried with this query..
select TN,Status_id
from PORT_DTLS
where Req_Start_Time between '8/11/2017 2:22:14.490361 PM'
and '8/12/2017 2:22:14.490361 PM';
But I am getting 'not a valid month' error.
Anyone please help me.
Your data looks like the column is a TIMESTAMP not a DATE. You should use an explicit formatting to cast those strings appropriately.
select TN,Status_id
from PORT_DTLS
where Req_Start_Time between to_timestamp('8/11/2017 14:22:14.490361' , 'DD/MM/YYYY HH24:MI:SS.FF')
and to_timestamp('8/12/2017 14:22:14.490361','DD/MM/YYYY HH24:MI:SS.FF');
I've assumed your dates are DD/MM; perhaps they are really MM/DD, in which case you need to tweak the format masks I posted. Most likely that ambiguity is why you're getting that ORA-01843 error.

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 want to convert date to some other format.
Below is the example 04/03/10 09:00:50.000000000 AMto YYYYMM
Iam not able to get this , below is the query which i used to convert.
select to_char(to_date('04/03/10 09:00:50.000000000 AM','MM/DD/YYYY HH:MM:SS AM'),'YYYYMM') from table;
Iam getting exception as below
ORA-01810: format code appears twice
01810. 00000 - "format code appears twice"
Format Code for Minutes is MI, not MM. MM is for months.
You are using 2-digit year. Better to use RR for this. Even better use 4-digit year.
TO_DATE doesn't store fractional seconds. You need to use TO_TIMESTAMP and use the FF as format code.
So, your query would be
select to_char(to_timestamp('04/03/10 09:00:50.000000000 AM','MM/DD/RR HH:MI:SS.FF9 AM'),'YYYYMM')
from table;
To achieve your goal there are many issues to resolve ;)
Finally I made this like that:
select to_char(
to_timestamp('04/03/10 09:00:50.000000000 AM','MM/DD/YYYY HH:MI:SS.FF9 PM',
'nls_date_language = ENGLISH'),
'YYYYMM') from dual;
A database column (VARCHAR2 datatype) stores the date/time as 13 digit (milliseconds
) unixtimestamp format. Now when I want to compare the column with a oracle date (in question), The error thrown as 'invalid number'
I tried both ways,
converting the 13digit number to Date and compare with the date in question like below. The expressions seems valid as they are printed in select query, but if i include in the where part, it throws 'invalid number'
Here 'value' is 13th digit unixtimestamp column of VARCHAR2 datatype.
select
TO_DATE('1970-01-01', 'YYYY-MM-DD') + value/86400000,
TO_DATE('2014-04-21', 'YYYY-MM-DD')
from dummytable
-- where and TO_DATE('1970-01-01', 'YYYY-MM-DD') + value/86400000 > TO_DATE('2014-04-21', 'YYYY-MM-DD')
converting the date in question to 13digit unixtimestamp and comparing with the database column.The expressions seems valid as they are printed in select query, but if i include in the where part, it throws 'invalid number'
.
select
value,
(to_date('2013-04-21', 'YYYY-MM-DD') - to_date('1970-01-01', 'YYYY-MM-DD')) * (1000*24*60*60)
from dummytable
-- where value > ((to_date('2013-04-21', 'YYYY-MM-DD') - to_date('1970-01-01', 'YYYY-MM-DD')) * (1000*24*60*60))
any pointers? Thanks in advance.
[EDIT- 1 day later] I see the problem now. There are some data (other rows) for the 'value' column that are non-numeric. But I have another column say field, where always field='date' return value as 13 digit timestamp. Now I think when 'where' condition executes, although the field='date' is in the condition, it is still validating the other values for 'value' which are non-numeric. Is there a way to avoid this ?
Your code works just fine. The problem is in your data. Some of your values is not a number.
create table test
(value varchar2(13));
insert into test(value) values('2154534689000');
--insert into test(value) values('2 54534689000');
select TO_DATE('1970-01-01', 'YYYY-MM-DD') + value/86400000
from test
where TO_DATE('1970-01-01', 'YYYY-MM-DD') + value/86400000 > TO_DATE('2014-04-21', 'YYYY-MM-DD');
This code works fine. But if you uncommented the second insert, you would get exactly the same invalid number error as you get.
UPD. Allan gave you a nice hint, but i feel that it can be good to explain you a bit about views. The fact that you select from a view CAN make a difference. A view is not stored somewhere physically, when you select from it, it is just "added to your query". And then Oracle Query Optimizer starts working. Among other things, it can change the order in which your where predicates are evaluated.
For example, your the view query can have a line where value is not null and it would normally show only 'good' values. But if your query has a predicate where to_date(value,'ddmmyyyy') > sysdate, Oracle can decide to evaluate your predicate earlier, because Oracle predicts that it would "cut off" more rows, thus making the whole query faster and less momery consuming. Of course, execution will crash because of an attempt to convert a null string to date.
I believe, that Allan in his answer that he gave a link to, gave a great way to solve this problem: "wrapping" your query in a subquery that Oracle can't "unwrap":
select value
from
(select value
from my_view
where rownum > 0)
where to_date(value,'ddmmyyyy') > sysdate
Hope that helps.
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.
I am executing the below query,It returns me the blank row.However there are records in the table having upd_time = '12-MAR-08'.I don't understand why it is not returning the date '12-MAR-08'.Please help me out??
SELECT br_data.upd_time FROM BANKREC.br_data
where br_data.upd_time = '12-MAR-08';
It's likely that upd_time isn't exactly 12-MAR-08. The date format is not showing the time component, but it's probably there (DATE data type in Oracle can contain both date and time components).
Try this (it will allow you to see the time components):
alter session set nls_date_format='DD-MON-YY HH24:MI:SS';
SELECT br_data.upd_time FROM BANKREC.br_data
where br_data.upd_time >= to_date('12-MAR-08','DD-MON-YY')
and br_data.upd_time < to_date('13-MAR-08','DD-MON-YY');
Is it the same if you do a
SELECT br_data.upd_time FROM BANKREC.br_data
where trunc(br_data.upd_time) = '12-MAR-08';
It could be that the upd_time is not a date, but a timestamp, so it actually contains for instance '12-MAR-08 05:30' which wouldn't be the same thing. trunc() removes the time part of the timestamp.
Since it doesn't return an error, I assume that it parses the date correctly, but otherwise you could try with to_date('12-MAR-08','DD-MON-YY')
You should use Oracle's function to convert your string properly into a date using
to_date('12-MAR-08', 'DD-MMM-YY')
Then you have to take into account that the Oracle "Date" datatype also contains time information to the nearest second. This means that the date that was constructed in the first step is actually midnight on March 12th. So you have to make sure that the upd_time is truncated to midnight:
trunc(upd_time, 'DAY') = to_date('12-MAR-08', 'DD-MMM-YY')
Your full query becomes
SELECT br_data.upd_time
FROM BANKREC.br_data
WHERE trunc(upd_time, 'DAY') = to_date('12-MAR-08', 'DD-MMM-YY');
There are other ways to skin this cat (you could transfer your updTime column to a proper char field with to_char(upd_time, 'DD-MMM-YY')), but it's usually advisable make the data you are looking for similar to what you can find in the database as that increases your chances of using an index for the lookup.
i don't have access to an oracle db at the moment but i remember using to_char.
try
SELECT br_data.upd_time FROM BANKREC.br_data where to_char(br_data.upd_time, 'DD-MON-YY') = '12-MAR-08';
