The Date type - a good practise

I am new to JDBC and have some problem using the Date type. When I deal with DB, I use the java.util.sql.Date, otherwise, I use the java.util.Date. Somehow, I need to do the conversion between date and year, month, and day. For some reason, a result of the conversion is total wrong in some situation but not all. Any advise on a good practise of using the two Date typies?
Thanks in advance.
v.

Just continue using the java.util.sql.Date instead of using the java.util.Date because the latter has a lot of deprecated methods. Try using java.util.Calendar to do your conversion between date and year, month, and day. Try using its setTime(java.util.Date) of the java.util.Calendar to set the current date. From there you can do the conversion. Don't attempt to convert the Date object you got from DB to java.util.Date. It's ok to use java.util.sql.Date for the Calendar.setTime() function since java.util.sql.Date is a subclass of java.util.Date.
I hope this helps.

What should be the data type for a field in ztable?

i am desing a ztable , wht should be the datatype for a field if i want to enter values like -1.5 and -2.5 , negative values with decimals what should be the data type???

declare as P type. TYPE P DECIMALS 1
Type P data allows digits after the decimal point. The number of decimal places is generic, and is determined in the program. The value range of type P data depends on its size and the number of digits after the decimal point. The valid size can be any value from 1 to 16 bytes. Two decimal digits are packed into one byte, while the last byte contains one digit and the sign. Up to 14 digits are allowed after the decimal point. The initial value is zero. When working with type P data, it is a good idea to set the program attribute Fixed point arithmetic.Otherwise, type P numbers are treated as integers.
You can use type P data for such values as distances, weights, amounts of money, and so on.

How do I detect the data type of a node?

Hello all,
I have a few quick questions about using Schema with XDK. I hope someone can answer this for me.
1) How do I detect the datatype of a node? I need to be able to detect if it is date/time, number or boolean
2) How do I then parse the string into date, number, etc. ?
3) Does Oracle SOAP also support this kind of thing? (ie. detecting the data type of a node and then parsing it?)
4) Does XDK support inline schema?
thanks in advance!

Thanks for the response.
So are you saying that it is not possible or not easy to detect the typed value data type of a node? In past years, I have had experience with converting based on what looks like a number and it is impossible to safely assume something is a number just because it looks like one. For example a Product ID could be: 14E1 which many routines would detect as a scientific notation number. This is why I need to be able to detect the data type.
But I am no Schema expert, but my understanding of schema is that simple types have standard designations. I think it is something like xsd:string or xsd:number, etc. But no matter what parser I look at them all seem to be implemented the same way and I can't figure out with any of them how to detect the datatype and then parse it appropriately. But it should be possible since it is written into the schema.
Since I'm using Jdev I'm hoping that the Oracle XDK can do this, if not does anyone know of any good parsers that can? I'm having trouble even locating validating parsers. Aside from Oracles all I could find were IBMs and Xerces which both seem to be based on the same thing anyhow.
Help or pointers in the right direction would be much appreciated since I have been struggling with this seemingly simple task for a long time.

Any idea what this errorr means? the data type of the reference does not match the data type of the variable

I am using Veristand 2014, Scan Engine and EtherCat Custom Device. I have not had this error before, but I was trying to deploy my System Definition File (run) to the Target (cRio 9024 with 6 modules) and it failed. It wouldn't even try to communicate with the target. I get the 'connection refused' error.
I created a new Veristand project
I added the Scan Engine and EtherCat custom device.
I changed the IP address and auto-detected my modules
i noticed tat Veristand didn't find one of my modules that was there earlier. (this week)
So, i went to NiMax to make sure software was installed and even reinstalled Scan Engine and Veristand just to make sure.
Now, it finds the module, but when i go to deploy it getsto the last step of deploying the code to the target, and then it fails.
Any thoughts?

Can you deploy if you only have the two 9401 modules in the chassis (no other modules) and in the sysdef? I meant to ask if you could attach your system definition file to the forum post so we can see it as well (sorry for the confusion).
Are you using any of the specialty configurations for the 9401 modules? (ex: counter, PWM, quadrature, etc)
You will probably want to post this on the support page for the Scan Engine/EtherCAT Custom Device: https://decibel.ni.com/content/thread/8671
Custom devices aren't officially supported by NI, so technical questions and issues are handled on the above page.

Not Able to Load the data type "Non Currency"in Planning accounts dimension

Dear All,
We are building Meta data in planning using HAL 9.2 ...while construction of accounts we were able to assign "Currency" Data Type ,but were unable to add the "Non Currency" data types to account members.
We have mentioned "Non Currency" in the the Data Type Field.
Thanks in Advance.

Hi Guys my issue is resolved..... just wanted to let you know that you will need to write "Non-Currency" in the field name in the csv for marking accounts as Non currency data type.

Can we change the data type of a field based on the value of the field

HI Gurus,
My Requirement is as below -- Could you please guide me
in the Printable Adobe form -- for ex - as usual for dates fields in the Object Pallette the object type is a date/time field and for quantity/currency fields corresponding fields are taken
now in case the either the date, quantity or currency is initial in place of displaying 0.00 or empty date we need to display N/A (Not Applicable)
for this I would like to change the data type of the field
to put it simply --
we need to change the data type of date field from DATE&TIME to Char type to hold N/A or Quantity field to Char field to hold N/A
how can we realize this in SAP adobe forms
Thanks in Advace
Ramchander Rao.K

Hello Ramchander,
     You cannot change the data type of the field at run time in Adobe forms because the type of field you choose at the time of design level is associated with the data type itself.
If you want to achieve your requirement, then your main idea should be to set the data type as CHARACTER itself while designing the field in the adobe form itself. CHAR field will comfortably hold the value of Calculation/amount field, Currency field, Amount, Date, Time HHMMSS, Unit Accuracy, Currency key, Floating point number, Numeric text, Client, Language and many other data types.
After designing the field as TEXT field in Adobe form you have two options.
Option 1:
Select the Date field initially as type TEXT field or CHAR field in Adobe forms.
Suppose the name of the field is TEXTFIELD1, then write the Javascript code on this field in Initialize event as below.
if ( this.rawvalue == null )
     this.rawvalue = "N/A";
If the field is not blank, then it will show the date. Else it will show "N/A".
Option 2:
Select the Date field initially as type TEXT field or CHAR field in Adobe forms. Do the formatting part in ABAP itself. It will increase the performance. Avoid Javascript as much as possible.
Suppose you have a DATE variable l_dats of type DATS. Then take another variable l_date of type CHAR. Then write the below ABAP code.
MOVE l_dats TO l_date.
IF l_date IS INITIAL.
     l_date = 'N/A'.
ENDIF.
Bind the l_date to the TEXT field in the form.
Even in this case, if the field is not blank, then it will show the date. Else it will show "N/A".
But I will suggest you to use Option 2 of keeping the AMOUNT, QUANTITY, DATE, TIME fields etc as CHAR or TEXT fields in Adobe form and do the required formatting in ABAP itself.

Can I modify the data type of a dynamic parameter?

I am using CR2008 against an Oracle 11 db and have a report with dynamic parameters.
One of the report sources is a custom view that selects all of the possible 'pay ending dates' where one of the fields from this view is used as the source for the dynamic parameter.
The view performs a TRUNC on the date field in an effort to eliminate the TIME component.
The problem is that the parameter definintion defaults to DATE/TIME (vs. just DATE). I'm wondering if there is any way to modify the data type of the parameter to be DATE only.
I've searched several forumns but have not found anything.
One solution I can think of is to have the custom view format the date field as a VARCHAR (sans the time component) which I assume would force the dynamic parameter data type to string, and then have the report perform a todate function on the value when applying the criteria.
Anyone else have an idea? Just seems like CR should allow the developer to specify the data type- especially b/w Date and Date/Time, rather than make an assumption.
Thank you in advance-
emaher

emaher,
Here's what you can do:
Leave the existing date column as it is in the view...
Just add another column to the view that casts the the date as a VarChar data type and formats the date as you would like it to be.
So now you'll have 2 date columns in the view... 1 that's still a date and another that a character string.
Now for your parameter, use the date version as the parameter value and the text version as the parameter description.
Be sure to set the "Prompt with description only" is set to true.
This way the user sees the LoV in the desired format but there's not need to wrangle it back into a date for data selection.
HTH,
Jason

How can I read the data type of a field in an MS Access database

I need to be able to determine if a field in an Access database is of a certain data type, and if it isn't, to change it to what it should be.

How to retrieve the data type of a column of a table?

Hi,
I want to retrieve the data type of a column of a table. At the moment I am querying "OCI_ATTR_DATA_TYPE" attribute but it is returning SQLT_CHR for both varchar2 and nvarchar2 data type columns. I need to distinguish between these two data types columns separately. Is there any API through which I could get the exact data type of a column i.e. "nvarchar2"?
Thanks in advance.
Hashim

Hi,
This is the Oracle C++ Call Interface (OCCI) forum - I'm not sure if you are using OCCI or OCI (Oracle Call Interface - the C interface) since you reference "OCI_ATTR_DATA_TYPE" which is more of an OCI focus than OCCI.
In any case, you might take a look at "OCI_ATTR_CHARSET_FORM" which takes the following values:
#define SQLCS_IMPLICIT 1 /* for CHAR, VARCHAR2, CLOB w/o a specified set */
#define SQLCS_NCHAR 2 /* for NCHAR, NCHAR VARYING, NCLOB */So, if you have a datatype of SQLT_CHR and OCI_ATTR_CHARSET_FORM is SQLCS_IMPLICIT then you have a varchar2 if it is SQLCS_NCHAR then you have an nvarchar2.
If you are using OCCI and not OCI then take a look at MetaData::ATTR_DATA_TYPE and MetaData::ATTR_CHARSET_FORM which expose OCI_ATTR_DATA_TYPE and OCI_ATTR_CHARSET_FORM respectively.
Perhaps that will get you what you want.

How to change the data type of an item in administrator

Hi,
A summary folder was created. One of the item in the summary folder is a sum. That sum item was created in the business area (based on another item). I can't refresh that summary folder because it gives me an oracle error (Ora-12008 and Ora-01401 the value is too large for the column). The column that this item is based on is of data type Number(13). How can I fix this problem without changing the column's data type of the original table? I already tried altering the data type in the EUL table via TOAD.
Thanks!

You really don't need to sum the item before hand if you are going to create a summary!

Change the Data Type of a Standard Required Field

Hello Experts,
Need to know if is it possible to change the data type of a standard field. The field is marked as a required field.
For example: If a standard field is an Object Picker and I would like to change it to a string field. Is it possible? How can I do it?!
Many thanks,
Igor Nakamura

Hi Igor,
Since you cannot hide a required field, what you can do is move the standard required field to someplace less noticable (like the bottom of the page) and then use a validation script to set it to some benign value.

Hi Pabitra......
From the SE11 change the table as u wanted and then from menubar select
UTILITIES--> DATABASE UTILITY
It will open database utility
there u select the Activate and adjust database button.
then the database table will get adjusted.
just try it once.........
