Timestamp data

I need a very accurate timestamp to go along with my acquired data. Tried the Elapsed time.vi, but not getting reliable results. Does anyone have any suggestions. Any help is greatly appreciated. Right now i am just using # of times loop ran, i am attaching my vi, disregard data global.vi these can just be indicators.
Thanks
Mike

Hello Mike,
some things are not perfect with your vi, just have a look at it now...
The value at "Wait until next multiple" is completly wrong! Have a look
at the help!
Why don't you use "Get Date/Time in seconds" or "Tick Count" as your time stamp?
Best regards,

Migrating Sybase "timestamp" data type to Oracle DB

Hi,
We are migrating huge Application currently running on Sybase database
to Oracle 10.2.0.3 (500+ Tables and Stored Procedures).
Have following questions regarding this Migration.
1) Many of the Sybase Tables have column which is of Sybase data type "timestamp".
Do you have any recommendation what is the data type to be used in Oracle for
migrating "timestamp" data type in Sybase?
2) How should we migrate existing data and business logic residing in Sybase for
data columns of Sybase data type "timestamp" ?
Given below are details on how we use Sybase timestamp Column in our Application
and we are trying to arrive at the best Solution that is possible for migrating
all those Tables and related business logic to Oracle.
We have following Control Table in Sybase which has column of timestamp data type and
some other Business keys.
sp_help EQP_IES_CRE_TIMESTAMP (This is similar to desc <table> command in Oracle)
EQP_IES_CRE_TIMESTAMP,dbo,user table
default,Nov 14 2001 10:39AM
CRE_TIMESTAMP ,timestamp,8,,,0,,,,0
REF_NUM ,char,30,,,0,,,,0
REC_UPD_DT ,datetime,8,,,1,,,,0
EQP_IES_CRE_TIMESTAMPI1,clustered, unique located on default, CRE_TIMESTAMP, REF_NUM, REC_UPD_DT,0,0,0,
Following is the overall logic used in Sybase
-- Step 1: Based on Event, populate Control Table with new Row.
-- CRE_TIMESTAMP timestamp Column gets auto-populated by Sybase
insert EQP_IES_CRE_TIMESTAMP (REF_NUM, REC_UPD_DT)
values (@uuid_ref_num, @event_cre_dt)
Since CRE_TIMESTAMP is auto-populated, it does not appear in above INSERT statement.
-- Step 2: Store timestamp value populated by Sybase in previous step,
-- to variable @event_timestamp. This value would be referenced
-- later in other SQL statements
select @event_timestamp = CRE_TIMESTAMP
from EQP_IES_CRE_TIMESTAMP
where REF_NUM = @uuid_ref_num
and REC_UPD_DT = @event_cre_dt
-- Sample value for @event_timestamp could be '001c0000182f2089'
-- It is not very readable or understandable
-- Step 3: Delete Control Table entry made in Step 1
delete EQP_IES_CRE_TIMESTAMP from EQP_IES_CRE_TIMESTAMP
where CRE_TIMESTAMP = @event_timestamp
-- Step 4: Make use of saved timestamp value from Step 2 to trigger queries
-- against other Tables that have timestamp Columns
-- Some sample queries are as shown below
delete eqp_staging
where event_timestamp > @event_timestamp;
insert into eqp_movement values(@event_timestamp, ......other columns) ;
Any idea how above Table and logic could be migrated to Oracle DB
We would also like to know how data values that currently exist
in Sybase Tables should be populated in Oracle .
Any suggestions or tips would be greatly appreciated
Thanks
Auroprem

Hi All,
Thanks for your responses.
We have decided on Solution to migrate "timestamp" Column from Sybase to Oracle, that is
specific to our Application needs.
Following is what we decided:
1) Create RAW Column in Oracle which would contain data Replicated from Sybase "timestamp" Column as is.
2) Create additional Column of INTEGER data type to store number equivalent of Sybase "timestamp" column
which would be more usable and consummable in Oracle as compared to RAW datatype.
3) Write Row-Level INSERT/UPDATE Trigger on migrated Oracle Table to populate INTEGER Column using
SQL Function TO_NUMBER(<raw_column_value>, 'xxxxxxxx').
4) Applications that access this Table, upon migration to Oracle, will now start referencing INTEGER Column
newly defined, and populated via Trigger.
Please let us know if you see any issues with this approach
Thanks

How to add TIMESTAMP data type in Enterprise Architect...?

Hi all
There is no data type of timestamp in Enterprise Architech. There is only
DATE type. I have ERD prepared from Enterprise Architech. How to modify
DATE type to TIMESTAMP type.
How to add TIMESTAMP data type in Enterprise Architect or in ERD ?
Thanks in advance,
Pal

Have you asked this question of the vendor of Enterprise Architect? They may have a later version that supports the various TIMESTAMP data types. If your ERD tool doesn't support a data type, other than talking to the vendor or working around the problem (i.e. generate DDL to a text file and edit it before applying it to the database), you're probably out of luck.

Queries involving where clause with timestamp data type

I need to use milliseconds in my tables and do queries where I compare the time in the table to a specific time. I changed the column to the TIMESTAMP data type (from DATE) to accommodate the milliseconds.
I am accessing the data via a C++ program using ODBC to access the Oracle 10g XE database and a SQLBindParameter statement to set up the comparisons.
Below is a table that looks like mine but simplified to just a few fields:
. DATA_ID NOT NULL NUMBER(10)
. START_TIME NOT NULL TIMESTAMP(6)
. STOP_TIME NOT NULL TIMESTAMP(6)
My query is:
. string sql("select "\
. "to_Char(rv.start_time, 'YYYYMMDD HH24:MI:SS.FF3'), "\
. "to_Char(rv.stop_time, 'YYYYMMDD HH24:MI:SS.FF3'), "\
. "rv.data_id "\
. "from "\
. "Reservation rv "\
. "where "\
. "rv.data_id = ? and "\
. "rv.stop_time >= to_timestamp(?, 'YYYYMMDD HH24:MI:SS.FF3') and "\
. "rv.start_time <= to_timestamp(?, 'YYYYMMDD HH24:MI:SS.FF3');");
MY C++ code (minus the usual statement preparation material) is:
. string startTime("20090826 15:42:02.000");
. string stopTime("20110828 02:04:52.000");
. SQLRETURN rc = SQL_SUCCESS;
. SQLINTEGER sqlRsrcInstanceId = resource->getResourceInstanceId();
. SQLLEN sqlRsrcInstanceIdLI = 0;
. rc |= SQLBindParameter( stmtHandle, 1, SQL_PARAM_INPUT,
. SQL_C_LONG, SQL_INTEGER, 0, 0,
. &sqlRsrcInstanceId, 0, &sqlRsrcInstanceIdLI );
. SQLCHAR sqlStartTime[24];
. memset(sqlStartTime, 0, 24);
. SQLLEN sqlStartTimeLI = SQL_NTS;
. strncpy( (char*)sqlStartTime, startTime, 23);
. rc |= SQLBindParameter( stmtHandle, 2, SQL_PARAM_INPUT,
. SQL_C_CHAR, SQL_CHAR,
. sizeof(sqlStartTime)-1, 0,
. &sqlStartTime, sizeof(sqlStartTime)-1,
. &sqlStartTimeLI);
. SQLCHAR sqlStopTime[24];
. memset(sqlStopTime, 0, 24);
. SQLLEN sqlStopTimeLI = SQL_NTS;
. strncpy( (char*)sqlStopTime, stopTime, 23);
. rc |= SQLBindParameter( stmtHandle, 3, SQL_PARAM_INPUT,
. SQL_C_CHAR, SQL_CHAR,
. sizeof(sqlStopTime)-1, 0,
. &sqlStopTime, sizeof(sqlStopTime)-1,
. &sqlStopTimeLI);
When the statement is executed, I get the following error:
. ODBC Return Code: SQL Error.
. Native Error Code/Message:
. 932/[Oracle][ODBC][Ora]ORA-00932: inconsistent datatypes: expected - got -
Any suggestions on what is wrong or a better way to perform the query?

The only way to test a query is to get out of your environment and fire up SQL*Plus (command line).
I can not read all of what you wrote but the error you are generating should show up there along with sufficient information to quickly fix it.
Once you have working statement put it back into your environment.

How to parse timestamp data

Hi,
I am not able to parse timestamp data. I am bringing this timestamp from AD through LDAP attribute through java code. I want date and time from this timestamp so that I can compare it with another date and time and get the difference between the two.
If anybody knows the solution for this then please let me know.
Thanks,
Kalpana.

Hi Kalpana,
try this to convert AD date to java date format
     final long FILETIME_EPOCH_DIFF = 0xa9735dcc400L;
     final long HUNDRED_NANO_PER_MILLI_RATIO = 10000L;
     long activeDirDate = 129476773898586231L;
     long l1 = activeDirDate / 10000L;
     long l2 = l1 - FILETIME_EPOCH_DIFF;
     Date newdate = new Date(l2);
     System.out.println("AD Date is in Java Date format : "+newdate);
Thanks,
Pallavi

Working with timestamp data type.

Hi all!,
I have some problems working with the timestamp data type.
Let's say that i have a table named order, where i store (in two timestamps) the date where the order was made, and the date where the order was executed.
I want:
1) first to find the difference between these to timestamps, let me call them a,b,
2) to find the average time of the difference of timestamps. With that i mean if my table has 60 typles for examples to get (b-a)/60.
Can these happen?
Thanks in advance,

I would do this with a view and a stored procedure within oracle.
Create a view that contains the two timestamp fields & the difference between them (along with any primary keys from the original table), then use this view in a stored procedure to average the values.

Write to measurement file loses timestamp data in tdms format

Hello all, I'm using the Write to Measurement File expressVI and I have created a loop in order to be able to individually label the column headers for each data signal that I'm writing. However, while the loop is successful in doing this the resulting TDMS file that the expressVI creates ends up losing the timestamp data that is used to record the time for each row and just writes a '0' instead. The timestamp data is present before the loop that adds column headers, which I have verified by adding an expressVI just before the loop. Please see the attached code for clarification.
How do I regain the timestamp info after the for loop executes and adds column header info? Thank you.
Attachments:
Write to measurement file specify column name.vi ‏106 KB

The problem with Express VIs and with the Dynamic Data wire is that they (almost) complete obscure what is being done "under the covers". They manipulate data in ways that are unseen and often unexpected. While they allow beginners to do extremely simple tasks quickly, they can easily lead to situations such as you are discovering.
If what you want to do is to write a TDMS data file, you should probably investigate the TDMS functions on the File I/O palette. I've not used TDMS myself, but I know there are examples and documentation in the LabVIEW Help. I suspect that if you do go with straight TDMS, you will probably save yourself further problems by not bundling your four inputs into a Dynamic Wire, but making them a 1D Array (or possibly a Cluster).

How to get java.sql.Timestamp data from database

Hello, i'm new to EJB and i can't get java.sql.Timestamp data, but when i'm trying to get java.lang.String data it works fine.
* @ejb.finder
* query="SELECT OBJECT(c) FROM userSCHEMA AS c
* WHERE c.lastName LIKE ?1
* AND c.firstName LIKE ?2
* AND c.registeredDate < ?3"
* signature="java.util.Collection findPatient * (java.lang.String lastName,
* java.lang.String firstName,
* java.sql.Timestamp)"
<method-params>
<method-param>java.lang.String</method-param>
<method-param>java.lang.String</method-param>
<method-param>java.sql.Timestamp</method-param>
</method-params>
Where i made a mistake ?

The main problem that I'm faced with, is that the
java.sql.Timestamp now has only one constructor, it
takes "long", i.e., milliseconds.That's because a Timestamp is just an offset from a particular instant of time. It doesn't have a timezone.
Please note that I'm not trying to "print", i.e., I'm
not interested in using the SimpleDateFormat.Then what are you interested in? You appear to be trying to create a Timestamp with a particular timezone, which doesn't make sense as I already noted. Is there a reason for this?

I want to write timestamp data to an image file

I have used the ImaqdxReceiveTimeStamp to receie timestamp data and would like to save this data to an image file. The calibration data gets written but teh timestamp data does not. Is there a way to do thisother than rewwriting the keys to the data into the image file via write IMAQ custom data and redo the work already doene to receive these keys?

IMAQ Write Image And Vision Info File 2 should save all the custom keys as well as calibration data (at least it is documented to..). Are you sure it isn't being written?

Timestamp data from OracleDataReader

Hi. I have an OracleDataReader that has a TIMESTAMP as one of it's fields. What is the correct way to preserve the contents of this field (including fractional element) in a .NET DateTime object?
Thanks
KH

Thanks Neeraj. However I was hoping to build classes that are agnostic of the provider (ie. use only native .NET types) once I have got the data out of the database - I cannot assume that the Oracle dlls have been installed on the machine that is ultimately consuming my classes.
Any chance of a sample that shows how to get TIMESTAMP data to/from a DateTime object? DateTime goes down to tick (nanosecond) resolution so this should be possible so long as TIMESTAMP(6) is used.
Many thanks
Kevin

Timestamp/Date format error with Java 1.6

I'm getting this error trying to getObjects from a ResultSet query for an Oracle Lite 10G table that has colums of the TIMESTAMP or DATE type. This works fine under java 1.5. Java 1.6 seems to have broken TIMESTAMP/DATE compatibility with Oracle Lite. Are there any plans to make 10G compatible with Java 1.6? We would like to port our application from Java 1.5 to 1.6, but this is an obstacle. I suppose one work-around would be to use TO_CHAR on all the DATE fields and convert them back to java Dates programatically, but that would be a hassle.
Update: I changed the column types of the table from TIMESTAMP to DATE. The same exception occurs when calling POLJDBCResultSet.getObject() on the DATE columns. Again, this works fine under Java 1.5, but not 1.6.
java.lang.IllegalArgumentException: Timestamp format must be yyyy-mm-dd hh:mm:ss[.fffffffff]
     at java.sql.Timestamp.valueOf(Timestamp.java:194)
     at oracle.lite.poljdbc.LiteEmbResultSet.jniGetDataTimestamp(Native Method)
     at oracle.lite.poljdbc.LiteEmbResultSet.getVal(Unknown Source)
     at oracle.lite.poljdbc.POLJDBCResultSet.getTimestamp(Unknown Source)
     at oracle.lite.poljdbc.POLJDBCResultSet.getObject(Unknown Source)
     at oracle.lite.poljdbc.POLJDBCResultSet.getObject(Unknown Source)

I just found a pretty easy java work-around for this that doesn't involve changing the table column types or the SQL:
Check the column type from the ResultSetMetaData before calling ResultSet.getObject(). If the type is DATE, TIMESTAMP or TIME, call ResultSet.getString() which doesn't throw an exception. Then convert the string to a java.util.Date using java.text.SimpleDateFormat. That can then be used to instantiate a Timestamp.
This seems to work.

What happens between the timestamp 'Date Sent' and 'Execute from'

Hi all,
from SXMB_MONI, I found that some messages take a long time, for example:
Date Sent            23.09.2008 02:22:39
Time Taken to Process (Secs)    0,5044590
Execute From         23.09.2008 02:23:12
To                   23.09.2008 02:23:13
Status Set           23.09.2008 02:23:13
you can find that there are about 30s between the 2 timestamps.
does anybody know what does the timestamp 'Date Sent' mean? and what does the 'Execute From' mean?
what happens between these 2 timestamps?
Regards,
Bean

Hi,
I can't find date sent there...
Executed from and executed to means times, where message went in to IE and out from IE. For example, if any error occurs, there can be difference 2 days (mapping fails, you correct it and restart the message). So the start will be at 21.10.2008 but end 23.10.2008). But generally, this time comrpises:
message routing & mapping
Olian
after list all of the messages in SXMB_MONI, click the column 'EndTime', you will find the 'Date Sent'.

Quirk with storage VI's and timestamp data.

This is a minor bug (since it's easy to work around if your aware of it)
I'm running LV 8.0.1 and writing a timestamp through the Write Data Storage VI, will store different times
depending on whether I pass just the timestamp in or the timestamp wrapped in an array. The timestamp
wrapped in an array is accurate, but a single timestamp is by 10 hours behind (and considering that I'm in
the PST (GMT-8:00) timezone), I'm not sure why it's 10 hours off.
I attached a VI that demostrates what is happening. The workaround for now is just to wrap timestamps in arrays
before sending them into the write data storage vi.

Ejb datacontrol, query panel with timestamps / date field errors

Hi,
I made an ejb datacontrol on a session bean in jdev 11g ps1 and used the named criteria of this entity in the data control to create an af querypanel. This works well.
first thing I cannot configure a date picker with time on this timestamp field (only date ).( does not matter what I configure in the entity datacontrol xml , it does not work )
and displaying the timestamp field in a inputData ( result table ) and showing the time also does not work either.
When I use in the query panel a between query operator on this date or timestamp field I get this error.

Timestamp data type on S[range C on E] constant value-based range windows

Hello,
My questiong is about how can we use timestamp value on S[range C on E] constant value-based range windows.
I have a LotEvent which i should collect and sum lastQty data for last ten minutes of market time (sendDate)
A normal [range 600] query does not work for me because i would like to use the exact time which data has been generated by the market (sendDate).
Here is the event;
public class LotEvent{
     private Double totalQty;
     private float lastQty;
     private String symbol;
     private String messageType;
     private Integer dataInterval;
     private String sendDate;
send date is always in "MM-dd-yyyy HH:mm:ss" format.
I have tried to use the following query but this gives an error;
Invalid statement: "select symbol, sum(lastQty) as lastQty, 10 AS dataInterval
+from lotInputChannel [range INTERVAL "0 0:0:15.0" DAY TO SECOND on >>sendDate<<]+
group by symbol"
Cause: Datatype char is not valid for value based windows
Action: Use a valid datatype for value based windows>
Here is the CQL;
<?xml version="1.0" encoding="UTF-8"?>
<wlevs:config xmlns:wlevs="http://www.bea.com/ns/wlevs/config/application">
<processor>
<name>lotProcTenMin</name>
<rules>
     <query id="tenMin"> <![CDATA[select symbol, sum(lastQty) as lastQty, 10 AS dataInterval
            from lotInputChannel [range INTERVAL "0 00:10:00.0" DAY TO SECOND on sendDate]
group by symbol]]> </query>
</rules>
</processor>
</wlevs:config>
i have tried this cql after changing the sendDate data type to long which is the time in milliseconds value but it did not work.
select symbol, sum(lastQty) as lastQty, 10 AS dataInterval
from lotInputChannel [range INTERVAL "0 00:10:00.0" DAY TO SECOND on to_timestamp(sendDate)]
group by symbol
The query above does not work also when sendDate is a String in "MM-dd-yyyy HH:mm:ss" format
At last i tried the following query with sendDate as time in milliseconds (long) value. It works! but i still would like to know how to use timestamp in S[range C on E] queries
select symbol, sum(lastQty) as lastQty, 10 AS dataInterval
from lotInputChannel [range *600000* on sendDate]
group by symbol
public class LotEvent{
     private Double totalQty;
     private float lastQty;
     private String symbol;
     private String messageType;
     private Integer dataInterval;
     private long sendDate;
Could anybody please help me with this issue?

It seems that you should configure the channel "lotInputChannel" as an application timestamped channel.
You can do that as follows -
- Have "sendDate" as a long and let its unit be milliseconds
- Use the following child elements of <channel> for the "lotInputChannel"
<wlevs:application-timestamped is-total-order="true">
<wlevs:expression>sendDate*1000*1000</wlevs:expression>
</wlevs:application-timestamped>
The multiplication by 10^6 is required since the units need to be converted into nanos
With this, you could use the query -
select symbol, sum(lastQty) as lastQty, 10 AS dataInterval
from lotInputChannel [range 10 minutes]
group by symbol
Of course, for the above to work, a requirement is that the value of "sendDate" is non-decreasing.
That is if e1 is before e2 in the "lotInputChannel" then e1.sendDate <= e2.sendDate

Is there table/Report history including timestamp & date for activity type created?

Hi Guys
I have an audit request for activity type that should include Date of creation/change and timestamp for them, but I don´t know if there is a table or report
that I should run.
Actually in KP26 in section line item shown the dates but by activity type, I expect to run in mass
I really appreciate if someone have suggestion or idea how is possible to get information with dates and timestamp

Hi Marco,
If not in standard, this can be achieved by customized field in the table. This is called Append Structure and you can add Z table.
Talk to an ABAP person. He can do it.
I know I have not answered you in a straight way
Regards,
Krishnendu.
