Using Long Data type in the Page

Hi ,
I have a page (in multiple page creation form ) which is suppose to contain only the NOTES field of the entity being created . The Notes field is defined as LONG data type in the table.
Two Doubts.
1. As of now in Jdev , u only have Varchar2 data type when assigning to any messageText layout item. What should be the max value set for Max Lenght of this field on the form . I suppose its 32k+ ,since its Long Field .
Anybody has used Long notes field before ??
2. This page has only one item on it , ie Notes ,which i have defined as messageRichText as style. I have been trying to resize this item ,so that it stretches out on entire page . But it just doesnt resizes .. any idea ..below is my PG.xml code
<?xml version = '1.0' encoding = 'UTF-8'?>

thanks

Hi Padma,
Thanks for reply !!
The width is still pain point for me ,as i am unable to increase its width .
I tried increasing the width of the table to 100%, however ,it still doesn work .
Any pointers ??
If you have used this widget before , could you assist me with any sample code u hv ??
I would really appreciate it
thanks

Problem to get ResultSet when it is used a Date type in the query condition

hello ,
I having a bit of nightmare getting a ResultSet how result of one simple Query for a table when the condition WHERE involve a Date type.
To change the String value in a date to use in the query condition, I tried both:
String strDate = "dd/mm/yyyy";
(1.) java.sql.Date sqlDate = new java.sql.Date(strDate.getTime() )
(2.) SimpleDateFormat formatter = new SimpleDateFormat(strDate) ; sqlDate = formatter.parse(strDate);
and finally I use this code to get the ResultSet:
sql = "SELECT * FROM myTable Where (idCli = " + cd_Cli + " And dateReg = " + sqlDate + ")";
statement = connection.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
resultSet = statement.executeQuery(sql);
boolean ok = resultSet.last();
totNumberOfRegistration = resultSet.getRow();
But In both the cases I get a empty resultSet.
I shoul like if someone would look my code to say me where it is the mistake...
thank you
tonyMrsangelo
P.S. I tryed using PrepareStatement too to get the ResultSet, but in that case I couldn't use the ResultSet because executing the statement resultSet.last() I get the error: "Result set type is TYPE_FORWARD_ONLY"

In a database like Oracle, you need to use a function like TO_DATE; other databases may have something similar.
However, the proper way to do this is to use a PreparedStatement. Then you can say
PreparedStatement ps = conn.prepareStatement("update SOMETABLE set SOME_DATE=? where SOME_ID=?");
ps.setDate(1, new java.sql.Date(someJavaUtilDate.getTime()));
ps.setInt(2, theId);
ps.executeUpdate();

Using DBMS_DATAPUMP with LONG data type

I've got a procedure below that calls the DBMS_DATAPUMP procedure using a REMOTE_LINK to move a schema from one database to another. However, a couple of the tables within that schema have columns with the LONG data type. And when I run it I get an error saying that you cannot move data with the LONG data type using a REMOTE LINK. So no data in those particular tables gets moved over.
Has anyone else had this issue? If so, do you have a work around? I tried adding a CLOB column to my table and setting the new CLOB to equal the LONG, but I couldn't get that to work either...even when I tried using a TO_LOB. If I could get that to, then I could just drop the LONG, move the schema, then recreate the LONG column on the opposite side.
Here's my procedure....

But the application we have that uses the database cannot be changed to read from a CLOBWhy can't you change the application?
Well, anyway you should point out to your superiors that Oracle documented years ago to not use LONGS anymore...
http://download.oracle.com/docs/cd/B19306_01/server.102/b14220/datatype.htm#sthref3806
It clearly states:
LONG Datatype
Note:
Do not create tables with LONG columns. Use LOB columns (CLOB, NCLOB) instead. LONG columns are supported only for backward compatibility.
Oracle also recommends that you convert existing LONG columns to LOB columns. LOB columns are subject to far fewer restrictions than LONG columns. Further, LOB functionality is enhanced in every release, whereas LONG functionality has been static for several releases.
How do I go from CLOB to LONG?I'm sorry, cannot help you on that one, I don't think you can do that at all (Oracle wants us to stop using LONGS, so, it's a one-way conversion...):
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1037232794454#15512131314505
So: NO built_in, you'll need to write a program if the clob is ALWAYS LESS THAN 32k in size, you can use plsql..but is that the case in your case? Only you know that.
I believe that question is still unanswered on this forum, but you might try searchin for answers on this forum, and
the 'Database-General' forum: General Database Discussions
Perhaps you can google a Q&D workaround...
( And consider convincing your collegues to just convert your LONGS to LOBS)

ADF View Object query to use Oracle LONG data type

Hi,
I'm using a view object that uses Oracle LONG data type.The following exception is thrown
*"java.sql.SQLException: Stream has already been closed"* and it is not fetching the correct data.
I have searched in many forums,they suggested to use LOB instead of LONG as LONG is deprecated. But in my case I can't avoid using LONG as some of my legacy applications using the same DB.
Please suggest me a way
Thanks in Advance
Felix

Thanks for your reply Arun,
I have solved this problem using the solution suggested by this blog [AskTom-Link|http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:839298816582]
In the above blog link,they have suggested to convert Long to Varchar by functions and asked to use this function in the column.
Thank you all guys who have seen this post.

Felix

How can I retrieve a LONG data type using ADO

In VB I am using an ADODB object to retrieve data from an Oracle table that has a LONG data type column...
specifically: SELECT TRIGGER_BODY FROM USER_TRIGGERS WHERE TRIGGER_NAME = 'MYTRIGGER'
I have tried using the GETCHUNK method but it only returns the first 150 or so characters no matter how
many times I call it???? here is the sample code I'm using........
Dim Cn As ADODB.Connection, Rs As ADODB.Recordset, SQL As String
Dim sChunk() As Byte
Set Cn = New ADODB.Connection
Set Rs = New ADODB.Recordset
Cn.CursorLocation = adUseServer
Cn.Open "Provider=OraOLEDB.Oracle.1;Password=hrzadmin;Persist Security
Info=True;UserID=hadmin;Data Source=xxx.local"
SQL = "SELECT trigger_body from user_triggers where trigger_name = 'MYTRIGGER'"
Rs.Open SQL, Cn, adOpenStatic, adLockReadOnly
Debug.Print Rs!trigger_name
Debug.Print Rs!trigger_body
sChunk = rs.Fields("trigger_body").GetChunk(500)
Debug.Print sChunk

I have a similar code which works for chunk size >400,
The image I am trying to retrieve is huge so the chunksize is also more.
Did you try with any non meta table?
For your reference I am pasting my application code below.
Hope it helps.

What is the maximum length of LONG data type in Forms 6i?

What is the maximum length of LONG data type in Forms 6i?

Do you mean the maximum size of a LONG that Forms 6i can display or the maximum size that can be stored in the database which sits behind your Forms application?

TIPS(63) : LONG DATA TYPE의 LENGTH 구하기

제품 : PL/SQL
작성날짜 : 1999-04-15
TIPS(63) : LONG DATA TYPE의 LENGTH 구하기
=========================================
PURPOSE
다음은 function 을 적용할 수 없는 long data type 의 length 를
구하는 방법을 소개한다.
Explanation
Long DataType 에 대해 Length 를 구하려 하는 경우 다음과 같은 Error 가 발생한다.
SQL> create table TOY
2 (Toy_ID NUMBER, Description LONG);
Table created.
SQL> select LENGTH(Description) from TOY;
select LENGTH(Description) from TOY
ERROR at line 1:
ORA-00932: inconsistent datatypes
"Inconsistent DataTypes" Error 는 LONG DataType 으로 정의된 Column 에
Function 을 적용하였기 때문에 발생한다.
VARCHAR2 Type 을 사용하면 정상 처리할 수 있으나, Oracle7 에서는 VARCHAR2 는
2,000 Characters 만 저장할 수 있으며, Oracle8 에서는 4,000 Characters 이다.
Oracle8 에서는 Long Data 를 저장하기 위해 LOB DataType 을 사용할 수 있으며,
LONG Data Type 은 Oracle7/Oracle8 모두 Support 되므로 LONG Type 에 대해
Length 를 확인하는 방법을 알아본다.
Example
다음은 anonymous PL/SQL Block 을 통해 TOY Table 에서 LONG Column 의
Length 를 구하는 Script 이다.
1. Single Record 에 대한 예
$ vi len_long.sql
declare
length_var NUMBER;
cursor TOY_CURSOR is
select * from TO;
toy_val TOY_CURSOR%ROWTYPE;
begin
open TOY_CURSOR;
fetch TOY_CURSOR into toy_val;
length_var := LENGTH(toy_val.Description);
DBMS_OUTPUT.PUT_LINE('Length of Description: '||length_var);
close TOY_CURSOR;
end;
SQL> set serveroutput on
SQL> @len_long
Length of description : 21
PL/SQL procedure successfully completed.
2. Multiple Record 에 대해서는 cursor FOR Loop 를 사용한다.
$ vi len_long.sql
declare
length_var NUMBER;
cursor TOY_CURSOR is
select * from TOY;
toy_val TOY_CURSOR%ROWTYPE;
begin
for toy_val in TOY_CURSOR loop
length_var := LENGTH(toy_val.Description);
DBMS_OUTPUT.PUT_LINE('ID: '||toy_val.Toy_ID);
DBMS_OUTPUT.PUT_LINE('Length of Description: '||length_var);
end loop;
end;
SQL> set serveroutput on
SQL> @len_long
ID: 1
Length of Description: 21
ID: 2
Length of Description: 27

Hi Frank,
I have the exact same scenario where I have huge data coming from DB and its a must that I provide pagination.
I tried implementing as per the document but the pagination is not working for me too.
Details of the scenario:
1. I have a session facade method which takes a searchCriteria (custom criteria) as the input parameter and returns a list of entities.
a)This is the first method that I call as a default method activity in my taskflow.
b)The result of this method is dragged and dropped as table in the jsff. (*which created a methodIterator in pageDef unlike the documentation which has accessorIterator*).
2. I declared 2 class level variables
a) List<Entity> result: which is set once the method in the (1) above is executed.
b) long size: which is also set from the method (1) above.
3. I defined getEntityAll(int index,int range) method which returns List<Entity> as per the index and range using the result (class level variable populated by method in 1)
4. I defined getEntityAllSize() method which returns the size (class level variable populated by method in 1).
5. I created the datacontrol on top of the session facade bean.
6. I made sure to change the DataControlHandler = "oracle.adf.model.adapter.bean.DataFilterHandler"
7. I've set the rangeSize = 25 in my pagedef.
Now when I run my page, my default method activity calls the method in (1) above and populates the table, with a scroll bar.
Once I start scrolling, it calls my method in (1) but it does not call either of the methods (getEntityAll(int index,int range) & getEntityAllSize()) which adds the pagination behavior.
After this, my table has just 25 rows and further scrolling does not invoke any of the methods from the session bean.
I'm using jdev : JDEVADF_11.1.1.4.0_GENERIC_101227.1736.5923 (11.1.1.4.0).
Please let me know if I am missing anything.
Thanks in advance!

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.

Need to convert long data type to varchar2

I need to convert a long datatype in an existing table to a
varchar2, in either another table or view. I have a 3rd party
application which needs to query the data in the long data type,
but it can "handle" the long.
What is the best way to do this? I tried to make a trigger, but
I must be missing something. Here is the trigger.

create another table with clob datatype
1)create table clob_tab(pkval number,clob_col clob);
2) insert into clob_tab (select pkval,to_lob(long_col) from
long_tab);
3) use dbms_lob package to do string manipulation using
substr,instr functions on clob column.

How to deal with LONG data type in RTF template

Hi,
I'm developing a PO request report in which I should print some attachments. The attachments are stored in the database in table fnd_attachments_long_text in column long_text which data type is LONG. In my case the content of the column long_text is always plain text.
The query I use to get the text from the table is something like:
select long_text
from fnd_documents_long_text
where <some_conditions....>
The query runs fine in SQL developer but when I run the XML report I get following error: "Stream has already been closed". The XML file generated is complete in its structure but the XML node which should contain the text of the attachment is empty, therefore I cannot print the attachment in the report.
I made some researches on metalink and I've found note 832903.1 which explains the same error I'm getting. Looks like I cannot execute more than 1 query using the same JDBC connection if one of these queries retrieves a LONG data type.
Any advice on how can I get the attachment text to show correctly in my report?
Thank you

Hi,
Thank you for your reply,
Yes, I tried to get the text as described in that article but maybe I'm missing something because my data template doesn't show the attachment text.
The article talks about support for BLOB, CLOB and RAW and at the end it states "but we do not have support for RAW and LONG column types at the moment - we're looking into that for a future release". So this makes me think that I won't be albe to retrieve my text since it's stored in a LONG column.
I think that the error I'm getting is not strictly related to XML publisher but it is in some way related to the JDBC connection used to get the data. Infact I have an old version of the same report I'm trying do develop which is made in Report Builder and it is retrieving the attachment text correctly.
Right now I'm trying to use the Report Builder engine to get the XML data and then use XML Publisher to create the PDF output. Anyway, if it is possible, I would like to avoid Report Builder and use only XMLP.
Thanks

Error in getting Long data type from Table

Hi All,
I have one table say xx_long. In this table one column is having Long data type.
Now I want this values will get in to the PL/SQL variable. I taken variable data type as long but it is showing error "ORA-00997: illegal use of LONG datatype".
Sample code with which I tried:
declare
a long;
begin
select slno into a from xx_long where slno = 100;
dbms_output.put_line('Value:'||a);
end;
Please help me on this.
Thanks in advance.
Regards,
Hari

LONG columns cannot appear in certain parts of SQL statements:
WHERE clauses, GROUP BY clauses, ORDER BY clauses, or CONNECT BY clauses or with the DISTINCT operator in SELECT statements
The UNIQUE operator of a SELECT statement
The column list of a CREATE CLUSTER statement
The CLUSTER clause of a CREATE MATERIALIZED VIEW statement
SQL functions (such as SUBSTR or INSTR)
Expressions or conditions
SELECT lists of queries containing GROUP BY clauses
SELECT lists of subqueries or queries combined by the UNION, INTERSECT, or MINUS set operators
SELECT lists of CREATE TABLE ... AS SELECT statements
SELECT lists in subqueries in INSERT statements

1. Export and import
2. Sql*Plus 'copy' command
It is a good idea to move from 'LONG' to 'CLOB'.

Using CLOB data type - Pros and Cons

Dear Gurus,
We are designing a database that will be receiving comments from external data source. These comments are stored as CLOB in the external database. We found that only 1% of incoming data will be larger than 4000 characters and are now evaluating the Pros and Cons of storing only 4000 characters of incoming comments in VARCHAR2 data type or using CLOB data type.
Some of the concerns brought up during discussion were:
- having to store CLOBs in separate tablespace;
- applications, such Toad require changing defaults settings to display CLOBs in the grid. Default value is not to display them;
- applications that build web page with CLOBs will be struggling to fit 18 thousand chararcters of which 17 thousand are blank lines;
- cashing CLOBs in memory will consume big chunk of data buffers which will affect performance;
- to manipulate CLOBs you need PL/SQL anonymous block or procedure;
- bind variables cannot be assigned CLOB value;
- dynamic SQL cannot use CLOBs;
- temp tables don't work very well with CLOBs;
- fuzzy logic search on CLOBs is ineffective;
- not all ODBC drivers support Oracle CLOBs
- UNION, MINUS, INTERSECT don't work with CLOBs
I have not delt with CLOB data type in the past, so I am hoping to hear from you of any possible issues/hastles we may encounter?

Some of the concerns brought up during discussion were:
- having to store CLOBs in separate tablespace;They can be stored inline too. Depends on requirements.
- applications, such Toad require changing defaults settings to display CLOBs in the grid. Default value is not to display them;Toad is a developer tool so that shouldn't matter. What should matter is how you display the data to end users etc. but that will depend on the interface. Some can handle CLOBs and others not. Again, it depends on the requirements.
- applications that build web page with CLOBs will be struggling to fit 18 thousand chararcters of which 17 thousand are blank lines;Why would they struggle? 18,000 characters is only around 18k in file size, that's not that big to a web page.
- cashing CLOBs in memory will consume big chunk of data buffers which will affect performance;Who's caching them in memory? What are you planning on doing with these CLOBs? There's no real reason they should impact performance any more than anything else, but it depends on your requirements as to how you plan to use them.
- to manipulate CLOBs you need PL/SQL anonymous block or procedure;You can manipulate CLOBs in SQL too, using the DBMS_LOB package.
- bind variables cannot be assigned CLOB value;Are you sure?
- dynamic SQL cannot use CLOBs;Yes it can. 11g supports CLOBs for EXECUTE IMMEDIATE statements and pre 11g you can use the DBMS_SQL package with CLOB's split into a VARCHAR2S structure.
- temp tables don't work very well with CLOBs;What do you mean "don't work well"?
- fuzzy logic search on CLOBs is ineffective;Seems like you're pulling information from various sources without context. Again, it depends on your requirements as to how you are going to use the CLOB's
- not all ODBC drivers support Oracle CLOBs not all, but there are some. Again, it depends what you want to achieve.
- UNION, MINUS, INTERSECT don't work with CLOBsTrue.
I have not delt with CLOB data type in the past, so I am hoping to hear from you of any possible issues/hastles we may encounter?You may have more hassle if you "need" to accept more than 4000 characters and you are splitting it into seperate columns or rows, when a CLOB would do it easily.
It seems as though you are trying to find all the negative aspects of CLOBs and ignoring all the positive aspects, and also ignoring the negative aspects of not using CLOB's.
Without context you're assumptions are just that, assumptions, so nobody can tell you if it will be right or wrong to use them. CLOB's do have their uses, just as XMLTYPE's have their uses etc. If you're using them for the right reasons then great, but if you're ignoring them for the wrong reasons then you'll suffer.

REPLACE function on a long data type

How can I use the replace function on a long data type?
I am getting ORA-00932: inconsistent datatypes: expected CHAR got LONG

Thanks so much dainge! Your example helped me to do it. I guess the trick is to put the long datatype into the declared variable first. This is what worked (of course commit after):
declare
l long;
begin
select rppl_sql_statement into l
from rppl
where rppl_slct = 12128;
l := replace(l,'ROPPL96','ROPPL97');
update rppl
set rppl_sql_statement = l
where rppl_slct = 12128;
end;

LONG data types producing errors in 10.1.2.48.18

Maybe I should already know this but...
I am getting the " Internal Error has occured " message when I attempt to add a field which is defined as a LONG data type. Can Discoverer handle these fields ? If so is there a setting I am suppose to change ?
thanks
OBX

I know the BLOB problem has come up before as no, I don't think Discoverer will handle them directly (ie: there are example using pl/sql to handle the BLOB first).
However, I did try just pointing to the eul4_documents table where there is a BLOB (the actual workbook apparently). When I created the folder pointing to that Oracle table I did not get an error in Discoverer Admin.
Then I created a workbook against that folder bringing everything back. There is no data displayed for the BLOB (doc_document I believe), but I don't get an error. This was - as you may have gathered from the EUL tablename - using Discoverer v4.x. I wonder if it's now different in v10g?
Just an fyi.
