Timestamp conversion

Hi,
by definition timestmaps provide date/time in UTC. With knowledge of the timezone it should be possible to calculate the local date and time explicitly. But there is no such function available in HANA. I have a timestamp field on the DB (data type DEC15 or DEC21) and want to provide an additional calculated field, showing local date, or local date/time. There is function UTCTOLOCAL, but this requires wrong importing data formats:
utctolocal(datearg,timezonearg) since it requires a datearg instead of a DEC field. It is obvious, that a correct conversion is not possible without specifying the time additionally.
How am I able to convert a timestamp into DATE and TIME fields?
Thanks and regards,
Ulf

Hi Ulf
Yep, could be that this is not doable in a calculated attribute in an analytic view...
It perfectly works in SQL, so maybe you need to change your tool here.
create column table weired_timestamp (w_ts decimal (15,0))
insert into weired_timestamp values (20140305225959)
select w_ts, to_date(w_ts), to_time(w_ts), to_timestamp (w_ts) from weired_timestamp
W_TS
TO_DATE(W_TS)
TO_TIME(W_TS)
TO_TIMESTAMP(W_TS)
20140305225959
2014-03-05
22:59:59
2014-03-05 22:59:59.0
With that you can move on with the timezone conversion.
If wonder, why
1)    the documentation provides a hard coded example only that is not really helpful :
"SELECT UTCTOLOCAL (TO_TIMESTAMP('2012-01-01 01:00:00', 'YYYY-MM-DD HH24:MI:SS'), 'EST') "utctolocal" FROM DUMMY;
instead of a real scenario.
Well, obviously the person who wrote this hadn't had your scenario in mind.
As you're SAP internal, why don't you just provide feedback on that to the documentation team, maybe even providing an improved real-life example?
2)    the documentation doesn't refer to both scenarios, SELECTS and calculated fields in views
Likely because it's the SQL reference we are talking about here. But again, that can be a valid point for improvement - mention it to the documentation development team.
3)    the HANA documentation is wrong since utctolocal(datearg,timezonearg) should be
utctolocal(timestamparg,timezonearg) including the missing information how to convert ABAP timestamps (DEC) into HANA timestamps (whatever it is?).
Sorry, I don't get this.
HANA provides a specific SQL compliant data type called "timestamp". This is what the functions work upon and that is what the documentation is about.
HANA is a general DBMS platform that is not just there to support the odd ends of ABAP data modelling and encoding.
I agree that there should be documentation on how to deal with ABAP data types when working without an application server. However, this shouldn't be part of the general DB documentation.
Not sure if these things are already part of any ABAP on HANA education material, but the SoH content development teams surely have come across these things and very likely documented them.
As SAP employee you got access to that, so maybe this would be a good place to look for this kind of information for you.
If you still feel this is a bug, fell free and open a internal message on that.

Timestamp conversion problem.

I work in the development of a LabVIEW program that communicates with a
server (written in Java). All acquired data is sent via TCP and the
server can read everything (waveforms and other information). However,
there is a problem in timestamp conversion. We don't know how to
convert the milliseconds correctly. The timestamp is inside a waveform,
so we cannot convert it to formatted string.
Example:
Original timestamp:
13:37:19,639
11/10/2005
String generated with "Flatten to String":
0000 0000 BF71 9ABF A3D7 0800 0000 0000
Converted value (Java server):
13:37:19,000
11/10/2005
Does anyone know the algorithm to obtain the milliseconds from this value: "A3D7 0800"?
Thanks for attention.
My regards,
Vinicius Falseth
Solved!
Go to Solution.

There is a faster way. You can extract the timestamp from the waveform using Get Waveform Components.
At that point, you can convert it to whatever you want. Attached
is a VI which shows a simple conversion to milliseconds, losing a lot
of resolution (128 bit timestamp goes to 52 bit double) and a more
complex conversion showing the internal structure of the timestamp (it
is a 128 bit fixed point number with the decimal in the middle).
You can modify the second conversion to do such things as throw away
the integer portion to get higher resolution on the fraction. Or
you could just save to Java using a four-integer structure.

Help to create Materialized View that has timestamp conversion

I need help creating materialized view with timestamp conversion between GMT to LocalTime.
Feel free to make any comments.
Thanks in advance.
jon joaquino;)

Here is one way.
1. Alter the table hist_table and add a new column pdt_timestamp.
2. Update the new column using the function 'new_time'
For example,
Update hist_table
set pdt_timestamp = new_time(gmt_timestamp,'GMT','PDT');
3. create a materialized view log on the table 'hist_table' using the syntax
create materialized view log on hist_table
with primary key, rowid, sequence;
4. create a materialized view now using the syntax:
(You have to specify your own storage numbers and tablespace name)
create materialized view mview_hist_table
pctfree 0 tablespace mymview
storage (initial 16k next 16k pctincrease 0)
build immediate
refresh fast on commit
as select uid,gmt_timestamp,pdt_timestamp
from hist_table;
Please test on your test instance before doing it on production. I have tested this on Oracle 10g for Windows 2000. I assumed that column 'uid' is the primary key on the table. I hope this helps.

DB2 timestamp to oracle timestamp conversion

Does any one know how to convert Db2 timestamp into oracle timestamp.
From DB2 we are getting timestamp in this format (2000-03-06-16.02.19.074474) (26 bytes).
I want to insert this into oracle thru owb into oracle table with column type timestamp.
Does anyone know the procedure for this type of conversion
Thanks in advance..

Hi,
Try a migration tool at www.ispirer.com/chyfo.html
It provides you the fastest, the easiest and the most powerful way to migrate
DB2 database into Oracle.
It works in conjunction with Oracle SQL Loader. The tool creates text files (moving of LOBs are fully supported), generates
CREATE TABLE scripts for Oracle and control files for SQL Loader.
The tool has a lot of other features.

Unix timestamp conversion to human readable representation ...

Hi,
I map unix timestamps from MaxDB to the controller context of Web Dynpro and display the results in a table. Is there a smart way to convert the timestamps to human readable date and time? Maybe some way to manipulate the table values with a function before they are written ..?
For now, I create a new node in the context and manually set each value with the according date/time representation ... but thats pretty cumbersome.
Thank you very much for your help!
Cheers,
boris

Hi Boris,
Check http://java.sun.com/j2se/1.3/docs/api/java/text/SimpleDateFormat.html
Date currentTime_1 = new Date(longUnixTimestamp);
String dateString = formatter.format(currentTime_1);
I would suggest you to create a calculated attribute under the same node as initial timestamp value and return a result of SimpleDateFormat.format().
Best regards, Maksim Rashchynski.

You are right Gogineni, when I got the error, I was using %S in the format string for Format Date/Time String function and %3u in the format string for Scan From String.
I found the solution in this thread - use %S%3u in both places.

Error in timestamp conversion

I use an attribute definede oracle.jbo.domain.Timestamp but when I use the getTime() method I get an incorrect result (meaningless, sometime it reverse the natural time direction).
How can I solve that issue ?
TIA
Tullio

Did you create a TimeStamp attribute in the Entity Object?
This would be requried for sql type DATE attributes.
Using JDev 9i
You can create a date and time format (display both) to display an attribute value that is SQLType DATE, but you must first change the attribute type definition on the attribute's entity object to Timestamp. To change the attribute's type: Expand the Business Components project in the Navigator and locate the entity object that defines the attribute for which you want to create the format. Right-click the entity object in the Navigator and choose Edit EOName. In the Entity Object Wizard, select Attribute Settings and choose the desired attribute from the Select Attribute dropdown list. Note: By default the attribute should show a type of Date to match its database column type. Choose Timestamp from Type on the attribute settings page. Click OK to save the attribute with the new type.

Java time to DB2 timestamp conversion

I want to convert current time to following format "2008-01-12 11:46:55.945000". I tried but I an not able to do. Could you pelase hlep me out or is there any easy way to do
          Calendar calendar = Calendar.getInstance();
          //2008-01-12 11:46:55.945000
          int year = calendar.get(Calendar.YEAR);
          int date = calendar.get(Calendar.DATE);
          int month = calendar.get(Calendar.MONTH);
          int hour = calendar.get(Calendar.HOUR);
          int minite = calendar.get(Calendar.MINUTE);
          int second = calendar.get(Calendar.SECOND);
          int millisecond = calendar.get(Calendar.MILLISECOND);
          String timestamp = year+"-"+date+"-"+month+" "+hour+":"+minite+":"+second+"."+millisecond;

have you try like:
java.sql.Timestamp creationdate = new java.sql.Timestamp(new Date().getTime());
prepStmt.setTimestamp(1, creationdate);or format the date as "yyyy-MM-dd HH:mm:ss" like string by using SimpleDateFormat
and use
java.sql.Timestamp creationdate =
               java.sql.Timestamp.valueOf(creationDate);

10g Oracle Timestamp conversion to milliseconds

Hello!
I'm sure this is possible and I have found a couple of references but none that work.
How can I take an Oracle Timestamp and convert it using a SELECT statement into milliseconds?
Thanks in advance

It looked interesting but I don't think it is the answer.
Isn't the Oracle timestamp based on the elapsed seconds since some date in 1970 or something? It seems there should be an algorithm to convert but I just haven't found it.

Timestamp Conversion Function Module

Hi all,
>>We are bringing time stamp value (like 20072404161312) from CRM ,we need to convert into date & time. I need function module which one does this...
>>We are are storing the time duration in min format (its key figure). I need to populate in reports as HR:MN:SS , How we can do this? Is there any function module is available for this?
Thanks in Advance

Hello Arun,
The timestamp is in the format <date><time>. In your example (20072404161312), the date is 20072404 and time is 161312. You can transfer the timestamp into a string and then split the data. You can use the following ABAP code to separate the date from the time:
* w_ts is your timestamp, w_s is the temporary string
*w_date and w_time will be your final date and time.
data: w_ts type timestamp.
data: w_s type string.
data: w_date type sy-datum,
w_time type sy-uzeit.
w_ts = '20072404161312'.
* Here is the code you need:
w_s = w_ts.
w_date = w_s(8).
w_time = w_s+8(6).
Hope this helps.
Hope this helps.
