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.
Regards,
Felix

How To change the ADF View Object query where-clause at RunTime?

I am trying to create a simple display page which will display user data (username, assoc_dist_id, assoc_agent_id, status , etc). The User data is stored in a database table and i am using an ADF Read Only table based on the View Object to display the data on the JSF page.
However, i want to display only the users that a particular person accessing the page has the AUTH LEVEL to see. e.g. If the person accessing the page is an 'ApplicationAdministrator' then the page should display all users in the table, If its a 'DistributorAdministrator' then the page should display only users associated with that Distributor (i.e. assoc_dist_id = :p_Dist_id ) and If its an 'AgentAdministrator' , then the page should display only users associated with that Agent ( i.e. assoc_agent_id = :p_Agent_id).
Currently my af:table component displays all the users in the table because the query for the view object is (select * from users) . However, i want to use the same viewobject and just set the where-clause at runtime with the appropriate parameter to restrict the dataset returned.
Do anyone knows how to accomplish this ?

David,
See the custom method initializeDynamicVariableDefaults() in the SRViewObjectImpl.java class in the FrameworkExtentions project in the SRDemoSampleADFBC sample application. You can find out how to install the demo if you haven't already from the ADF Learning Center at:
http://www.oracle.com/technology/products/adf/learnadf.html
This class is a framework extension class for view objects that adds a neat, generic feature to be able to dynamic default the value of named bind variables. You can read more about what framework extension classes are and how to use them in Chapter 25, "Advanced Business Components Techniques" of the ADF Developer's Guide for Forms/4GL Developers, also available at the learning center above.
It is an example of generic framework functionality that "kicks in" based on the presence of custom metadata properties on a named bind variable. See section 25.3.3 "Implementing Generic Functionality Driven by Custom Properties" in the dev guide for more details. Using this sample code, if you add a bind variable to a view object, and define a custom metadata property named "DynamicDefaultValue" on that bind variable, and set this custom metadata property to the value "CurrentUser", then that bind variable will have its value dynamically defaulted to the name of the authenticated user logged in. If instead you set this custom property to the value "UserRole", then the bind variable will be set to the comma-separated string containing the list of roles that the authenticated user is part of.
Once you've created a framework extension class for view objects like this, you can have the view objects you create inherit this generic functionality.See section 25.1.4 "How to Base an ADF Component on a Framework Extension Class" in the dev guide for more info on this.
By adapting a technique like this (or some idea similar that better suits your needs) you can have your view object query contain bind variables whose values automatically take on the defaults based on something in the user-session environment.

Oracle Long Data type Problem

Hi,
I am using ORACLE 7.3.4 database. I am having a problem in updating a column of long datatype in a table t1 with another column from table t2 of long datatype. I have tried setting LONG 1000000 also but this doesn't work. I appreciate any kind of suggestions.
The error it gives is ORA-00997: illegal use of LONG datatype.
Thanks

I had the same problem too with a newest thin driver. I found that I can read all my characters (bytes) using getBinaryStream() and single-byte read(), but read() never returns -1; instead reading the character before last causes the ArrayOutOfBoundsException you mentioned.
So I just blindly caught the exception and let it go to QA. (sort of
InputStream r = rs.getBinaryStream(field);
if(r == null) ...
StringBuffer sb = new StringBuffer();
try { for(int c = -1; (c = r.read()) != -1;) sb.append((char) c); }
catch(IndexOutOfBoundsException e)
{} // ignore Oracle idiosyncrazy.
finally { r.close(); }
). Please note that getCharacterStream() or getAsciiStream() did not work for me. I did not try deprecated getUnicodeStream(): I decided I would better correctly extract characters in Java from binary data myself if I need them rather than allowing this junky thin Oracle driver to do an extra thing for me.

Can't update oracle Long data type

Hi All,
Setup
Weblogic 5.1.0sp11, oracle 8.1.6, Solaris8, classes12.zip,
Solaris_JDK_1.2.1_03a
ConnectionPool:
weblogic.jdbc.connectionPool.XXXDBPool=\
url=jdbc:oracle:thin:@10.2.30.50:1521:ZZZZ,\
driver=oracle.jdbc.driver.OracleDriver,\...etc
Problem
I can't seem to write to (insert/update) an oracle type Long column
using connections from the weblogic connection pool. Each entry(as
XML) into this column is fairly large (>1MB). Reading from works fine,
however.
The same configuration(minus connection pool and associated
code/config) via tomcat works fine(read/write), so I'm thinking the
weblogic connection pool is giving me a connection object which
doesn't update this Long column properly.
Using the usual(again works fine for tomcat) :-
//Url = jdbc:weblogic:pool:XXXDBPool
//driver = weblogic.jdbc.pool.Driver
stat = con.prepareStatement("UPDATE BM_RM_USER_DIARY set DIARY=? where
id=?");
//stat.setString(1,diaryData); //use an inputstream instead.
ByteArrayInputStream bais = new
ByteArrayInputStream(diaryData.getBytes());
//StringBufferInputStream bais = new
StringBufferInputStream(diaryData); //deprecated
stat.setAsciiStream(1, bais, bais.available());
stat.setLong(2,userId);
I'm not getting any errors from this update, so I can't really see
what I might be doing wrong. It just returns fine as if it has
succeeded (rows updated = 1)
Assuming I CAN NOT change these settings, are there any other ways I
can programmatically get these inserts working ? Is this even a known
issue ? as i can't find a problem in these postings that quite matches
mine.
Any help appreciated.
Cheers
Alkesh

Hi All
Just to follow up on this.
The problem was solved by explicitly calling commit() after
the update has taken place.
It seems as though my connection from the connection pool has
autocommit set to false.
Thanks

Create Tabel having LONG Data Type

HI Team,
I want to create table but for table i have 2 LONG data type is throwing error message please give the light

JustinCave wrote:
1) When you're getting an error, it's always helpful to include the error. Otherwise, we have to guess. And if we guess wrong, our answers will be incorrect and we'll waste everyone's time. Including the Oracle version is also useful.
2) Why, oh why would you want to use the LONG data type? That type has been depricated since 9.0.1. It was replaced by the CLOB data type (assuming you are storing large amounts of character data-- BLOB would be the replacement for LONG RAW columns). Data in a LONG is terribly difficult to work with in PL/SQL.
3) My recollection is that one of the (many, many, many) restrictions on a LONG is that you can only have 1 per table. I'm guessing that is the error you're getting (though if you post the error, I wouldn't have to guess).
Justin
Even oracle should probably re-consider its data dictionary views not to use long datatype.
e.g. Does not look perfect when you see LONG datatype for TEXT column in dba_views/all_views/user_views and that too in latest version Oracle 12c

Manik.

Oracle-specific data types vs Connection pool

Hi, using Oracle-specific data types such as
ArrayDescriptor and create it by a connection to an Oracle database from a WebSphere datasource throw a ClassCastException. There is no problem using these Oracle-specific data types when the connection is obtained via the DriverManager. WebSphere cannot fix the problem because these data types are
not part of the JDBC specification.
Some reply from Oracle?
Thank you very much.

Thank you but I there is no solution in that thread.
Also, I know that WebLogic from BEA has a way around this issue... No Websphere work around ?
No Oracle fixing ?
Thanks.

ADF panel does not prompt for variable defined in ADF view object.

I have created an ADF Panel, which allows the user to run a few simple queries against an Oracle database done using ADF view objects and ADF view links and ADF application module.
One of these queries lookup detail information about a given database object (Table, view or whatever) from dba_objects. The SQL uses a parameter (:P_OBJ_NAME) that has a default value of “Departments”. If I run the ADF application module by itself outside of the ADF panel, all works fine, it prompts me to provide a value for the parameter :P_OBJ_NAME.
As I said the panel contains the different ADF view links including the one that should prompt the user to provide a value for :P_OBJ_NAME. When I run the panel it does not prompt me for :P_OBJ_NAME, it just uses the default defined value “departments”.
I hope I described my problem for every one to understand. The question obviously is how do I get the ADF panel to prompt the user to provide a value for parameter :P_OBJ_NAME, my expectation was that since the sql in the view object and the application module both are designed to prompt for a value for this parameter then the panel should do just that but it does not.
You expert input would be most appreciated.
Thanks.

The prompting for a parameter is a feature we built into the ADF Tester - it is not a default behavior you get in your application when you just place a VO on your page.
To get something like this expend the operations node under the VO in the data control palette, and drag the "Execute with parameters" operation to your page to drop it as a parameter form.
This will provide your user a place to fill out the parameter and press a button to execute the query.

View object query bind variable

I have a bind variable in my view object query and "Required" is unchecked for it. Due to this JUnits are failing with the Missing IN or OUT parameter error. If I set the bind variable as required, the JUnits run fine.
But this bind variable is also used in several view criterias where it is set as Optional. So if I set the bind variable in the view object query as Required, will it affect the view criterias as well?

ADF View Object Capability

Usually I use ADF View Object when I want to view data from table in Oracle DB.
Now can View Object extract data from file? xml or csv format?

Hi,
no, ViewObjects work with queries against the database.

Issue with View object query

Hi,
I have extended my controller to add an additional condition to the view object query where I appen an add condition.If there is any kind of exception the add condition keeps on appending without refreshing the query to the orginal one.I have to clear the cache to be able to fix it
below is the peice of code.What should I do to be able to get the original query or refresh it because when i do a getQuery it keeps giving me the query with the earlier condition that I appended and again appends the new condition.
strQuery = oaviewobjectimpl.getQuery();
oaviewobjectimpl.setQuery(strQuery+" AND MtlCategoriesKfv.CONCATENATED_SEGMENTS = '"+strCategory+"'");
RequisitionAMImpl requisitionamimpl1 = (RequisitionAMImpl)oapagecontext.getApplicationModule(oawebbean);

Y don't u make a custom VO, as you are doing set query, i expect ur changing entire query of seeded VO, better to use custom VO here and attach it to required beans progrmatically.

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)

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.

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 .

Any pointers ??
If you have used this widget before , could you assist me with any sample code u hv ??
I would really appreciate it

Enforcing integrity using oracle specific data base commands .v. using fron

Full subject : Enforcing integrity using oracle specific data base commands .v. using front end.
It ought to be generally accepted that it is better to enforce integrity directly in the data base using constraints, dependencies, triggers etc rather than leaving it to specific front end programmes.
In my view, the chief advantages - of enforcing integrity directly in the data base - are:
(1) No process can violate the integrity.
(2) Being server centric, these commands run on the server and so can be easily sized in one place.
(3) One time data migration (imports) into the system using Oracle tools or SQL commands would also need to conform to the integrity constraints. Thus an implementor would be assured that the basic data is alright.
I am faced with a situation where we are about to implement a new Oracle based package. During data migration, when we discovered that there are no integrity constraints built into the target data base, the package vendor asserted that it is not necessary to build in integrity into the database. This seems to be an extreme and risky view.
Further, it is argued by the package vendor that putting constraints directly in the data base would significantly increase the needed resources (RAM) on the server. In my view, this increase is trivial and anyway, hardware costs are crashing day by day.
In the absence of integrity checks in the data base, it seems to me that every program would have to extra zero value work to ensure integrity of the end user data. It will still never be complete.
I would like to know the pros and cons of implementing without integrity constraints.
OK.

OK.It's a shame you seem to be so far into the process and committed to this vendor. I once had a vendor tell us his product would run on Oracle but they recommended MS SQL Server because "oracle can't handle more than 5 concurrent sessions." I made sure that vendor didn't make the short list.

How to display images in BI Publisher from a LONG data type

We are storing images in Oracle Database as LONG data type. When I am giving query in BI Publisher and view the XML generated, I am getting the following error.
name was started with an invalid character. Error processing resource 'http://.......
<X_SIGNATURE>"N!0$$$$$$$#B!0$$$"X$$$$!3$$$!2$$#a$$$!1$!1$$$$$d$$$$#7$"X!0$"}@E$e"1"XM">K#@!P!P!Ga}!1!@!P!C#C"O!>...
Can anyone suggest the solution?

Hi
my problem is, for each job_id there is many users. Oh that's something completlty different...
I Strongly Recommand to_
1.*create 2 tables Jobs & users*
2.*create a relation between them* 1 to many to get for each job more than a user that's the way that Must be -- execuse me the bad design of the db pulled u into this trap -
3.then u can deal with it normally no need to a sample code but just a form with Jobs as (Master) and Users as (detail) with a relation and with a simple query u can display each job_id is for many users.
no null values no commas r needed.
Hope this helps...
Regards,
Amatu Allah.
