How to suppress some lines from printing

Dear all
I have a problem of suppressing some lines in a character mode report depending on some condition. E.g. say I have 5 lines per record to be printed. Say Name, Add1, Add2, Add3, City. Now depending on a condition, I don't want to print Add2, instead Add3 and City should move upward one line resulting only 4 lines in the report. Like wise there may be only two lines in the report, Name and City only.
How to accomplish this task? Thanks in advance.

Easy in to do it in the query:
select rtrim(decode(adr1,null,null,adr1||chr(10))||
             decode(adr2,null,null,adr2||chr(10))||
             decode(city,null,null,city||chr(10))||
             country,
       chr(10))
from address

Since the word "TEXT" is formed of 4 letters, you would read the text file 4 bytes by four bytes. Wrong on two counts. First, the file may not be encoded 1 byte per character. It could be utf-16 in which case it would be two byte per character. Second, even if it were 1 byte per character, the string "Text" may not start on a 4 byte boundary.
Consider a FileInputStream object "fis" that points to your text file. use fis.read(byte[] array, int offset, int len) to read every four bytes. Convert the "TEXT" String into a byte array "TEXT".getBytes(), and yous the Arrays class to compare the equality of the read bytes with your "TEXT".getBytes()Wrong since it relies on my second point and will fail when fis.read(byte[] array, int offset, int len) does not read 4 bytes (as is no guaranteed to). Check the Javadoc. Also, the file may not be encoded with the default character encoding.
The problem is easily solved by reading a line at a time using a BufferedReader wrapping an InputStreamReader wrapping a FileInputStream and specifying the correct character encoding.

J4680 printing bottom half of some lines of print. What can be done?

HPJ4680 is printing only the bottom half of some lines. Can I correct this?

Hi @ReneePM,
Welcome to the HP Forums!
I noticed that your HP J4680 is printing bottom half of some lines of print. I am happy to help you with this printing issue!
For further assistance, I will need to know the following:
If you are using a Windows or Mac Operating System, and the version number. To find the exact version, visit this link. Whatsmyos.
If the printer is able to make copies.
If the power cable is plugged into a surge protector, or directly to the wall outlet. Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector. This applies to Inkjet printers as well.
Please see this post, Want Good Answers? Ask Good Questions, by @Bob_Headrick, so you can get the most out of these forums.
If you are using Windows please try the HP Print and Scan Doctor, and let me know what happens!
Thank you for posting, and hope to hear from you soon!

In alv report , how to reserve 20 lines from beginning of page

hi experts
in alv report , how to reserve 20 lines from beginning of page.
regards
subhasis.

If by reserve you mean should not move on scrolling then make them KEY from fieldcatalog.
But I think maximum of 10-12 can be handled by that.

How to export some data from the tables of an owner with integrity?

Hi to all,
How to export some data from the tables of an owner with integrity?
I want to bring some data from all tables in a single owner of the production database for development environment.
My initial requirements are: seeking information on company code (emp), contract status (status) and / or effective date of contract settlement (dt_liq_efetiva) - a small amount of data to developers.
These three fields are present in the main system table (the table of contracts). Then I thought about ...
- create a temporary table from the query results table to contract;
- and then use this temporary table as a reference to fetch the data in other tables of the owner while maintaining integrity. But how? I have not found the answer, because: what to do when not there is the possibility of a join between the contract and any other table?
I am considering the possibility of consulting the names of tables, foreign keys and columns above, and create dynamic SQL. Conceptually, something like:
select r.constraint_name "FK name",
r.table_name "FK table",
r.column_name "FK column",
up.constraint_name "Referencing name",
up.table_name "Referencing table",
up.column_name "Referencing column"
from all_cons_columns up
join all_cons_columns r
using (owner, position), (select r.owner,
r.constraint_name fk,
r.table_name table_fk,
r.r_constraint_name r,
up.table_name table_r
from all_constraints up, all_constraints r
where r.r_owner = up.owner
and r.r_constraint_name = up.constraint_name
and up.constraint_type in ('P', 'U')
and r.constraint_type = 'R'
and r.owner = 'OWNERNAME') aux
where r.constraint_name = aux.fk
and r.table_name = aux.table_fk
and up.constraint_name = aux.r
and up.table_name = aux.table_r;
-- + Dynamic SQL
If anyone has any suggestions and / or reuse code to me thank you very much!
After resolving this standoff intend to mount the inserts in utl_file by a table and create another program to read and play in the development environment.

Thanks, Peter.
Well, I am working with release 9.2.0.8.0. But the planning is migrate to 10g this year. So my questions are:
With Data Pump can export data just from tables owned for me (SCHEMAS = MYOWNER) parameterizing the volume of data (SAMPLE) and filters to table (QUERY), right? But parameterizing a contract table QUERY = "WHERE status NOT IN (2,6) ORDER BY contract ":
1º- the Data Pump automatically searches for related data in other tables in the owner? ex. parcel table has X records related (fk) with Y contracts not in (2,6): X * SAMPLE records will be randomly exported?
2º- for the tables without relation (fk) and which are within the owner (MYOWNER) the data is exported only based on the parameter SAMPLE?
Once again, thank you,

How to read some images from file system with webdynpro for abap?
Thanks a lot!

Hello Tao,
The parameter
icm/HTTP/file_access_<xx>
may help you to access the pictures without any db-access.
The following two links may help you to understand the other possibilities as well.
The threads are covering BSP, but it should be useful for WebDynpro as well.

How to exclude some tables from schema level replicatio????

Hi,
I am working on oracle10g stream replication.
My replication type is "Schema Based".
So can anyone assist me to undersatnd, how to exclude some tables from schema based replication.
Thanks,
Faziarain

You can use rules and include them in the rule set, lets say you dont want LCR to be queued for table_1 in schema SALES, write two rules one for DDL and another for DML with NOT logical condition.
DBMS_RULE_ADM.CREATE_RULE(
rule_name => 'admin.SALES_not_TALBE_1_dml', condition => ' (:dml.get_object_owner() = ''SALES'' AND NOT ' ||
' :dml.get_object_name() = ''REGIONS'') AND ' ||
' :dml.is_null_tag() = ''Y'' ');
DBMS_RULE_ADM.CREATE_RULE(
rule_name => 'admin.hr_not_regions_dlll',
condition => ' (:dml.get_object_owner() = ''SALES'' AND NOT ' ||
' :ddl.get_object_name() = ''table_!'') AND ' ||
' :dsl.is_null_tag() = ''Y'' ');
just go through this document once, http://download.oracle.com/docs/cd/B28359_01/server.111/b28321/strms_rules.htm#i1017376

How to stop Officejet 6210xi from printing logs

We inherited an officejet 6210xi. (No manual.) It is being used standalone as a fax. It now prints a log for each and every fax. This is a huge waste of paper, so how do we stop it from printing a log every time? Thanks.

Hi,
May be it is the alignment page. Please perform aligning the printer once as per the steps below and check if helps.
Follow these steps to open the printer toolbox and align the printer, if you found defects on the print quality diagnostic report.
1. Load plain white paper in the input tray.
2. Open HP Solution Center:
3. Click Settings.
4. Under Print Settings , click Printer Toolbox . The printer Toolbox opens in a new window.
5. Click the Device Services tab.
6. Click Align the Printheads .
The product aligns the printheads. When the alignment is complete, the product prints an alignment page.
After the successful alignment, restart the printer and check.

How to remove characters/lines from the beginning of an InputStream

Hi,
I have a program which receives several InputStreams. From each of these streams I have to remove 2 lines from the beginning. After the lines are removed, all the streams are combined to one with SequenceInputStream and read in one chunk. Is there an easy/simple way of doing this?
One option I thought would be to read the char by char until 2 end of line chars have been detected and then read the rest of the data to a buffer. And the create a ByteArrayInputStream out of this buffer. Problem with this approach is, that the amount of data can be large, so putting all the data in to memory might cause problems.
Another option is to use BufferredInputStream and use the readline() method twice to get rid of the lines that are not needed. After this I would write the data to some output stream, which is then converted back to input stream. Propably would work, but sound too much of work for a simple thing like this. There has to be better way.
To make it simple, what I need is a method that looks like the following, or something similar
* Removes n number of lines from the beginning of a InputStream.
* @param is InputStream where the lines are removed
* @param numberOfLines int value to indicate how many lines whould be removed
* @return InputStream where lines have been removed.
public InputStream removeLines(InputStream is, numberOfLines);Thanks.

Here's the code, feel free to use it. Comments are also welcome.
public InputStream removeLinesFromTheBeginning(InputStream is, int numberOfLines) throws IOException
          char c = 'c';
          int i = 0;
          for(int n = 0 ; n < numberOfLines ; n++)
               do
                    c = (char)is.read();
                    System.out.print(c);
                    if(c == (char)-1)     // end of stream reached before any newline characters were found.
                         return null;
                    i++;
               while(c != '\n');
               System.out.println();
               System.out.println("Characters removed:" + i);
               System.out.println("n: " + n);
               i = 0;
          return is;

Any hint on how to eliminate the highlighted lines from the output?
I played with calculated key figures but could not reason it out.

Create Conditions over the Formula. Since the sum would be always 0 only when both the KF's are zero I think you can create condition over this formula.
Would this help?

How to suppress blank lines in smartforms

Hi all,
     How can we suppress blank lines in smartforms?
In my scenario I am having customer address details in main window.
i.e. Name
     Street
      P O Box
      P O Box Location
      Post Code
      Telephone
      Fax.
Suppose if there is no value for P O Box Location the address is getting displayed as
      Name
     Street
      P O Box
                      -> Leaving blank space
      Post Code
      Telephone
      Fax.
But I want it as
     Name
     Street
      P O Box
      Post Code
      Telephone
      Fax.
i.e The blank line should not be displayed.
Kindly let me know how to do this.
Regards,
Neethupriya.

Hi Neethu,
Are you using ADDRESS option in smartforms or code to get address from customer master?
If you are using code, you can give condition like P O Box Location <> SPACE in condition tab.

either this way we can do this
1)
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
<b> factory.setIgnoringElementContentWhitespace(true); </b>
DocumentBuilder db = factory.newDocumentBuilder();
or
2)
java.io.StringWriter sw = new java.io.StringWriter();
