Manipulating with data types

I working with the serial com, thru RS-232.
I use byte[] to contain whatever that is returned from the device,
I do a direct, system.out.print(readBuffer); *readBuffer = byte[]
for example: the supposed value "FD" is shown as "-3" instead.
Quesions:
1. Is there a way to present the byte[] as a hexa representation? and how?
2. I wish to do a binary compliment of some hexa values, is there an operator for such?
i have tried...
byte[0].toString()
but given the error: byte cannot be dereferenced.
thanks in advance for the help! ^^

Hi,
1) Loop over the array, and use Integer.toHexString to create a hex string for each value.
2) Yes
bitwise or |
bitwise and &
bitwise xor ^/Kaj

JDBC MS Access--- cannot extract entry with null value with data type Meta

I'm trying to extract a data entry with null value by using JDBC. The database is MS Access.
The question is how to extract null entry with data type memo? The following code works when the label has data type Text, but it throws sqlException when the data type is memo.
Any advice will be appreciated! thanks!
Following are the table description and JDBC code:
test table has the following attributes:
Field name Data Type
name Text
label Memo
table contents:
name label
me null
you gates
Code:
String query = "SELECT name, label FROM test where name like 'me' ";
ResultSet rs = stmt.executeQuery(query);
while (rs.next())
String name = rs.getString("name");
rs.getString("val");
String label = rs.getString("label");
System.out.println("\t"+name+"\t"+label);
catch (SQLException ex)
System.out.println(ex.getSQLState());
System.out.println(ex.getErrorCode());
System.out.println("in sqlexception");
output:
C:\Temp\SEFormExtractor>java DBTest
yet SELECT name, label FROM test
null
0
in sqlexception

The question is how to extract null entry with data type memo?Okay, what you need to do is this:
if (rs.getString("val") == null)
// do something
}This way, when it's a null value, you can check it first, and then handle it how you want, rather than getting an exception.

Adding fields with data type "TIMS" to the BP transaction

hi all,
This is Anil regarding the addition of fields to the BP transaction.
here my problem is for BP transaction I could not find any BADI or screen exit to add the fields. Even EEWB tool does not allow us to cretate the fields with data type "TIMS". so could you please suggest any other way to add these fields to BP?
when I enter the values to the time fields in BP transaction, they must reflect in
BUT000 table also?
Regards,
Anil .

In the physical layer, Column Properties change the data type to int.
If still problem exists, In the Business Model, write a case statement like
case when column1=1 then 1 end
and apply count aggregation on the new calculated column,add the column to presentation table, use that new calculated column for report.

Issue with Data type 'Date' in Hyperion Planning V11.1.2.2

Hi,
I have created members with data type date. However when I save the date, it either disappears or comes up with a random date? Has any one come across this kind of problem before?
If so can you share the fix.
Thanks in advance for your help.
Cheers,
XXX

Hi
This problem is linked to you not having a consistent setting for your date input type.
So, go to application administration and set the date format to MM/DD/YYYY in application settings and display options, under current application defaults. Then after you have done this as a user go to User Preferences and display options and on the date format select the same. Or remove the Automatically detect.
I have seen this behaviour if you have Automatically Detect on the user preferences
Thanks

Need Help with data type conversion

Hello People,
I am new to java, i need some help with data type conversion:
I have variable(string) storing IP Address
IPAddr="10.10.103.10"
I have to call a library function which passes IP Address and does something and returns me a value.
The problem I have is that external function call in this library excepts IP Address in form of a byte array.
Here is the syntax for the function I am calling through my program
int createDevice (byte[] ipAddress).
now my problem is I don't know how to convert the string IPAddr variable into a byte[] ipAddress to pass it through method.

Class InetAddress has a method
byte[] getAddress() You can create an instance using the static method getByName() providing the IP address string as argument.

How to create an item with date type mm/yyyy (no day)

Hello,
Is it possible to create an item with date type mm/yyyy (no day)? I want the pop-up date picker to just show month and year.
Thanks,

Hi,
you cannot pop-up date picker to just show month and year, but you can set your item format as MM-YYYY
You can check this APEX_ITEM.DATE_POPUP2 at : http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21676/apex_item.htm#CHDJHBCG (if using apex 4.1) else http://docs.oracle.com/cd/E10513_01/doc/apirefs.310/e12855/apex_item.htm#CHDFDDEI

Manipulations with Date

i need to do some manipulations with dates, as like the following psuedo code.
date a=feb 14 2007;
date b=jan 31 2007;
date c=a+1; //this should do c=feb 15 2007
boolean before=b<a;//this should do as before= true
boolean after=b<a;//this should do as after=falsei searched in util.date of API. But some constructors that i cud use do this are deprecated.
So any ideas..

Date in general is deprecated.No, not at all. Just many of the methods are. Date
serves one role and calendar another.fusk u jverd u no nothing you pile of sh!t u got no
rite to correct me etc blah blah noob loses it :-)Good morning to you too. :-)
I never use Date. when would you prefer it over
Calendar?When I want to represent an instant in time without needing to worry about human imposed chunkification into months, days, etc. And I use SimpleDateFormat for going between human enterable/readable strings and the "raw" Date representation.
The only time I use Calendar is when I want to do day/week/month/year math on it, like "first day of the month" or "add one week" or "midnight on the day represented by this Date."

Difference between DEclaring Itab with DATA & TYpe Statement?

HI Friends,
What is the Difference between Declaring Itab with DATA & TYpe Statement?

Hi,
The Statements TYPES and DATA
Each ABAP program define its own data types using the statement.
TYPES dtype TYPE type ...
and declare its own variables or instance attributes of classes using the statement
DATA var {TYPE type} ...
Within the program or a class, you can also define local data types and variables within procedures. Local variables in procedures obscure identically-named variables in the main program or class.
When creating data types and data objects, there are a number of naming convention that also apply for other local program definitions, such as procedures. These are described in detail in the keyword documentation.
The Additions TYPE and LIKE
The additions TYPE type and LIKE dobj are used in various ABAP statements. The additions can have various meanings, depending on the syntax and context.
·        Definition of local types in a program
·        Declaration of data objects
·        Dynamic creation of data objects
·        Specification of the type of formal parameters in subroutines
·        Specification of the type of formal parameters in methods
·        Specification of the type of field symbols
TYPES: BEGIN OF struct,
         number_1 TYPE i,
         number_2 TYPE p DECIMALS 2,
       END OF struct.
DATA: wa_struct TYPE struct,
       number    LIKE wa_struct-number_2,
       date      LIKE sy-datum,
       time      TYPE t,
       text      TYPE string,
       company   TYPE s_carr_id.
This example declares variables with reference to the internal type STRUCT in the program, a component of an existing data object wa_struct, the predefined data object SY-DATUM, the predefined ABAP type t and STRING, and the data element S_CARR_ID from the ABAP Dictionary.
Reward Points if found helpfull..

Mapping Float with data type Qty or Curr or INT4

Hi,
We are extracting the data from a table. Some fields are defined as Float but at trasfer rules we have mapped those Key figures with Quantity or Currency or INT4 .
In transfer rules there is only info object mapping. But when extracting the data we are not getting any data even In PSA for those fields.
Please suggest should we change the data type or any changes
Thanks,
Shaliny. M

Hi,
Can you provide some more inputs.
have you mapped with Standard Fields.

Problems with date types

Hi guys,
i have a question regarding oracle and java dates. In my database i have a column defined as oracle Date type.
In my java application i need to compare these dates with the date took from the system.
In order to do this i use the SQL function to_char which converts the oracle data type to the type string.After this, i use the java class DateFormat to convert the strings to the java date type.When i have java dates i can do operations on them easly. My question is how i can realize the opposite process.For example, when i have updated a date with java, what i can do is converting it to a string, but then how the date could be converted in Oracle date type? (The attribute in my entity object is defined as oracle date )
Thank you

ADF use oracle.jbo.domain.Date, so you need to convert from java.util.Date and vice versa.
from oracle Date to java Date:
new java.util.Date(((oracle.jbo.domain.Date) oDate).dateValue().getTime());
from Java Date to oracle Date
new oracle.jbo.domain.Date(new Timestamp(date.getTime()));
If you are using JClient, this is a big problem. We have simmilar challenges in the lack of DatePicker until we implemented it ourselves:

Problem with data type 'STRING'

Hi All,
I have created a table named as zproject_mat and there is a field 'LONG_D' for long description and its size is not limited, so i used 'STRING' data type for this field. But the problem is: when i use this field in where condition with 'SELECT QUERY' in my abap program , it throws me an error..'The field long_d is a long string , so it cannot be used in WHERE, ON, or having conditions'.
Can anyone help me regarding this. I dont know which data type will be suitable in both conditions, LONG DESC AND SELECT QUERY.
Regards
Rahul

Hi Rahul,
As mentioned your Table name is 'zproject_mat' and there is a field 'LONG_D'.
The field 'LONG_D' will have a Data Element associated with it. Create a new input Data Element & Domain 'ZLONG' of Type CHAR with Length = 1100. This will used in the code.
For the Table 'zproject_mat', you need to need to break up your field as 'LONG_D1', 'LONG_D2', ........, 'LONG_D5' with Data Element as 'BAPI_MSG'.
To INSERT data in table:
In your code, you need to write your logic where the field 'LONG_D' is SPLIT into 5 words and saved in your table against the 5 fields.
To SELECT data from table:
In your code, again you need to write your logic where the field 'LONG_D' is SPLIT into 5 words as abaove and pass them to your SELECT query...
SELECT SINGLE *
FROM zproject_mat
INTO wa_zproject_mat
WHERE long_d1 = v_split1
AND long_d2 = v_split2........
AND long_d3 = v_split3.
The limitation of a table length is 4096 whereas of a field is 255 to make it RFC compatible. Table/Structure fields that are passed via RFC for integration have this limitation and to maintain database standards, these limitations exist.
Hope this helps.

Pranav.

How to enter values to a database table with data type 'LCHR'?

Hello All,
I have created a database table with five fields, of which the last field is 'Value' field in which i have to enter text with a maximum of 1000characters. I have also specified a 'Length' field preceding the 'Value' field.
The datatype specified for the 'Length' field is 'INT2' and for the value field is 'LCHR' with length 1000.
When i tried inserting values to the table through a report, the report is giving an error that 'Literals that take up more than one line are not permitted', which means 255characters.
Also, when i entered a short text which is less than 250 characters to the 'Value' field,, the report is working fine and the table entry is visible.
Can anyone help me in this?
It would be really helpful if you explain how to use 'LCHR' data type in tables and how to enter values to such a field with more than 255characters.
Thanks in Advance,
Shino

Hi shino,
Alternatively,
you can use STRING instead of LCHR.
I too have tried with LCHR and am facing the same issue.. i am not sure why its coming..
i have tried STRING and its working perfectly.
wa-key_field = 'IN4'.
CONCATENATE 'Long text over 200 chars length '
              'another Long text over 200 chars length '
              'another Long text over 200 chars length '
              INTO wa-long_text.
wa-len = strlen( wa-long_text ).
INSERT zshino_table from wa.
SELECT * FROM zshino_table INTO table it.
clear wa.
LOOP AT it INTO wa.
      WRITE:/ wa-len, ' ' , wa-long_text.
ENDLOOP.
Also, remember to set the type of the database field as String.
hope this was of some help,
thanks and regards,
Sagar.

Problem with Data Type

Hi,
I am performing SAP Production Order Confirmations (CO11N transaction) using an xMII BLT. In the CO11N screen, SAP doesn't let you type character values in the field 'Yield'. It is the same thing in xMII BLT where I have defined 'Yield' as the Data Type 'Double'. However, when I pass a character value for the input field 'Yield' from an Xacute query, I get the message 'Confirmation of order XXXXXXXX saved'. This is not correct because you can't have character values for the field 'Yield'. When I display the respective confirmation in SAP, the 'Yield' quantity is being shown as '0'. This is a discrepancy. To sum up, when you do a confirmation in the SAP screen CO11N it doesn't let you type a character value in the filed 'Yield' however, when you pass a character value from an Xacute query it accepts it as '0'. Can somebody tell me how I can fix this problem? Thanks.
Regards,
V M.

V_M,
The message 'Confirmation of order XXXXXXXX saved' is created within SAP, not from xMII. So the input filtering and error handling in the BAPI itself is not designed correctly. This is not all that unusual with BAPIs. Rather than simply testing performance in CO11N, I usually start with BAPI Explorer and use the single test functionality.
This is not a bug in xMII, but rather the normal (albeit, invalid) performance of the BAPI. It doesn't cause real problems within SAP since it records 0 (zero) as the quantity confirmed (Yield). The corrective action would be a custom BAPI and/or enter a CSS ticket for the BAPI. Remember that the BAPIs rarely (more likely, never) fully reproduce the internal functionality of the SAP screens.
SAP has error handling built into their transactions such as CO11N which prevent invalid entries. You may have to do the same in your transaction, web page, etc.
Hope this helps,
Mike

Looks like you have a custom function that is returning this error. Why don't you try using a character type element instead of numerical or decimal.
