I want to convert
SELECT CURRENT DATE FROM sysibm.sysdummy1;
to 20180119 (YYYYMMDD) rather than with the hyphen 2018-01-19 (YYYY-MM-DD)
Found out how to do this,
SELECT VARCHAR_FORMAT(current_timestamp,'YYYYMMDD') FROM SYSIBM.SYSDUMMY1;
Thanks for the help everyone!
If your Db2 server runs on Linux/Unix/Windows, then you can use:
select to_char( current date,'YYYYMMDD') from sysibm.sysdummy1;
See documentation here.
select int(current_date)
from sysibm.sysdummy1
and if you really want a string as asked...
select char(int(current_date))
from sysibm.sysdummy1
SELECT VARCHAR_FORMAT(CURRENT DATE, 'YYYYMMDD')
FROM SYSIBM.SYSDUMMY1
If above is not working, use below
SELECT VARCHAR_FORMAT(TIMESTAMP(CURRENT DATE), 'YYYYMMDD')
FROM SYSIBM.SYSDUMMY1

How can we convert timestamp to date?
The table has a field, start_ts which is of the timestamp format:
'05/13/2016 4:58:11.123456 PM'
I need to query the table and find the maximum and min timestamp in the table but I'm not able to.
Select max(start_ts)
from db
where cast(start_ts as date) = '13-may-2016'
But the query is not returning any values.
Please help me in finding the max timestamp for a date.
CAST(timestamp_expression AS DATE)
For example, The query is : SELECT CAST(SYSTIMESTAMP AS DATE) FROM dual;
Try using TRUNC and TO_DATE instead
WHERE
TRUNC(start_ts) = TO_DATE('2016-05-13', 'YYYY-MM-DD')
Alternatively, you can use >= and < instead to avoid use of function in the start_ts column:
WHERE
start_ts >= TO_DATE('2016-05-13', 'YYYY-MM-DD')
AND start_ts < TO_DATE('2016-05-14', 'YYYY-MM-DD')
Format like this while selecting:
to_char(systimestamp, 'DD-MON-YYYY')
Eg:
select to_char(systimestamp, 'DD-MON-YYYY') from dual;
If the datatype is timestamp then the visible format is irrelevant.
You should avoid converting the data to date or use of to_char. Instead compare the timestamp data to timestamp values using TO_TIMESTAMP()
WHERE start_ts >= TO_TIMESTAMP('2016-05-13', 'YYYY-MM-DD')
AND start_ts < TO_TIMESTAMP('2016-05-14', 'YYYY-MM-DD')
You can try the simple one
select to_date('2020-07-08T15:30:42Z','yyyy-mm-dd"T"hh24:mi:ss"Z"') from dual;
You can use:
select to_date(to_char(date_field,'dd/mm/yyyy')) from table
I'd go with the following:
Select max(start_ts)
from db
where trunc(start_ts) = date'13-may-2016'
If you have milliseconds in the date string, you can use the following.
select TO_TIMESTAMP(SUBSTR('2020-09-10T09:37:28.378-07:00',1,23), 'YYYY-MM-DD"T"HH24:MI:SS:FF3')From Dual;
And then convert it to Date with:
select trunc(TO_TIMESTAMP(SUBSTR('2020-09-10T09:37:28.378-07:00',1,23), 'YYYY-MM-DD"T"HH24:MI:SS:FF3')) From Dual;
It worked for me, hope it will help you as well.
This may not be the correct way to do it. But I have solved the problem using substring function.
Select max(start_ts), min(start_ts)from db where SUBSTR(start_ts, 0,9) ='13-may-2016'
using this I was able to retrieve the max and min timestamp.
How do I add date format (DD-MM-YYYY) in this query? I've added date format after sysdate but it shows missing right parenthesis error.
select EXTRACT(MONTH FROM (SYSDATE,'DD-MM-YYYY'))-level mn1
from dual
connect by level<4;
This should produce output like the following:
01-NOV-15 01-OCT-15 01-SEP-15
You should use ADD_MONTHS() and then TRUNC() to first date. Finally, convert to the format to ant using TO_CHAR()
select TO_CHAR(TRUNC(ADD_MONTHS(SYSDATE,-level),'MONTH'),'DD-MM-YYYY') mn1
from dual
connect by level<4;
Try in this format.
select EXTRACT(MONTH FROM (SYSDATE,'DD-MM-YYYY')-level) mn1
from dual
connect by level<4;
I just want to format current date into yyyymmdd in DB2.
I see the date formats available, but how can I use them?
http://publib.boulder.ibm.com/infocenter/dzichelp/v2r2/index.jsp?topic=%2Fcom.ibm.db2z10.doc.intro%2Fsrc%2Ftpc%2Fdb2z_datetimetimestamp.htm
SELECT CURDATE() FROM SYSIBM.SYSDUMMY1;
I dont see any straightforward way to use the above listed formats.
Any suggestion?
SELECT VARCHAR_FORMAT(CURRENT TIMESTAMP, 'YYYYMMDD')
FROM SYSIBM.SYSDUMMY1
Should work on both Mainframe and Linux/Unix/Windows DB2. Info Center entry for VARCHAR_FORMAT().
One more solution
REPLACE (CHAR(current date, ISO),'-','')
select to_char(current date, 'yyyymmdd') from sysibm.sysdummy1
result: 20160510
This isn't straightforward, but
SELECT CHAR(CURRENT DATE, ISO) FROM SYSIBM.SYSDUMMY1
returns the current date in yyyy-mm-dd format. You would have to substring and concatenate the result to get yyyymmdd.
SELECT SUBSTR(CHAR(CURRENT DATE, ISO), 1, 4) ||
SUBSTR(CHAR(CURRENT DATE, ISO), 6, 2) ||
SUBSTR(CHAR(CURRENT DATE, ISO), 9, 2)
FROM SYSIBM.SYSDUMMY1
Current date is in yyyy-mm-dd format. You can convert it into yyyymmdd format using substring function:
select substr(current date,1,4)||substr(current date,6,2)||substr(currentdate,9,2)
I have this value of date in database: 01-03-12 13:25:50. How I can select this date in this format: DD.MM.YYYY . I try to round it: ROUND(to_date(datum_zalozeni, 'DD-MM-YYYY HH:MI:SS'),'DAY') but format is still same...
Use TO_CHAR(datum_zalozeni, 'DD.MM.YYYY')
Official docs for TO_CHAR: http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions180.htm
Formats for dates: http://docs.oracle.com/cd/B19306_01/server.102/b14200/sql_elements004.htm#sthref416
If it is a DATE then you can do this:
select to_char( mycol, 'DD.MM.YYYY') from mytable;
Try this:
select to_char(datum_zalozeni, 'DD-MM-YYYY')
to_char(to_date(datum_zalozeni, 'DD-MM-YYYY HH:MI:SS'),'DD.MM.YYYY')
Currently I'm using MyTimeStampField-TRUNC(MyTimeStampField) to extract the time part from a timestamp column in Oracle.
SELECT CURRENT_TIMESTAMP-TRUNC(CURRENT_TIMESTAMP) FROM DUAL
This returns
+00 13:12:07.100729
This works OK for me, to extract the time part from a timestamp field, but I'm wondering if there is a better way (may be using a built-in function of ORACLE) to do this?
What about EXTRACT() function?
You could always do something like:
select TO_DATE(TO_CHAR(SYSDATE,'hh24:mi:ss'),'hh24:mi:ss') from dual
I believe this will work with timestamps as well.
You want just date then use
to_char(cast(SYSDATE as date),'DD-MM-YYYY')
and if you want just time then use
to_char(cast(SYSDATE as date),'hh24:mi:ss')
the parameters are making all the changed
'DD-MM-YYYY'
and
'hh24:mi:ss'
This may help:
Select EXTRACT(HOUR FROM (SYSDATE - trunc(sysdate)) DAY TO SECOND ) From dual;
select TO_DATE(TO_CHAR(SYSDATE,'hh24:mi:ss'),'hh24:mi:ss') from dual
This gives the timestamp for 1hour less than the actual.
select hour(CURRENT_TIMESTAMP)
