Scrollable recordsets

I'm using OAS 4.0.8 on Windows NT 4.0 with Oracle 8i release 2 (8.1.6) and JDeveloper 3.0
I have developed a servlet accessing the database using JDBC thin driver given by JDeveloper. The servlet is deployed in OAS. It doesn't support scrollable recordset. Does my OAS 4.0.8 support JDBC 2.0 API. If not can i download the driver from any of the sites? or is there any alternative?
pls advice me on the same.
tx and regards,
null

Which jdk is you app server using? It sounds to me as if you are using jdk1.3 for testing at a standard java application but you app server is using jdk1.2 or thereabouts. You are using scrollable result sets which are a new addition to the jdk (as of 1.3 I think), you should be careful when using scollable result set becuase alot of jdbc drivers do not support them. Just try to use next() and the get methods on result set. In a carefully designed method you should not need any more than this. Be careful if your app server is only using 1.2.2, if you decide to try to get it to work with 1.3 you could get some funny errors.

ODBC Driver adds ROWID next to SELECT and disables the optimizer hint

I want to use an optimizer hint in my sql statement. For example: "select /*+ index(emp,status) +*/ status,name from emp where status=1". I have a bitmap index on status field, i want to force the select statement to use it. This one works fine from sql plus. If i execute the same statement from a VB application and run it via ODBC [Microsoft driver or oracle driver] it's sending the statement like "select rowid,/*+.....+*/ ...". I believe hint has to be next to the word SELECT, so it's not being used. I want to create an ADO connection from the vb application and create a recordset and loop through it and update some values. Any thoughts?
I tried some other options...like
select * from (select /*+ index(1,2) +*/....)
select a.* from (select /*+ index(1,2) +*/...) a
cn1.execute(sqltext) from vb..
In all these three methods it's not adding a rowid next to select.. so hint is used and able to use the index. But having issues with updating the recordset. It says "query is not from one table" and "can't be updated" errors..

The ODBC drivers are going to need to select the rowid in order to get an updatable or a scrollable recordset. Otherwise, they won't know which row in the database to update or how to fetch the previous rows without caching the entire recordset.
Can you create a view from the hinted select statement and select from that? That's likely to be the fastest solution.

Recordset per message in Sender File Adapter

Hi Friends
I have configured a sender file adapter to pick up *.txt files from a specific path, Since the file is having thousands of records it is failing to process the file at PI level . In order to avoid the problem I have kept Recordset Set Per Message as 10 , but still PI is processing all the records into a single message. Please help me in troubleshooting it.

Multiple tables in a recordset.

Hi all,
I have got a bit stuck with creating an advanced recordset that calls from multiple sub tables. I have created the SQL statement below (originally used inner joins but the code got too long and still didn't work).
SELECT *
FROM Main_Table, Table_1, Table_2, Table_3, Table_4, Table_5, Table_6, Table_7, Table_8, Table_9, Table_10, Table_11, Table_12, Table_13, Table_14, Table_15
WHERE
(((((((((((((((((Main_Table.ID_1 = Table_1.ID_1),
Main_Table.ID_2 = Table_2.ID),
Main_Table.ID_3 = Table_3.ID),
Main_Table.ID_4 = Table_4.ID),
Main_Table.ID_5 = Table_5.ID),
Main_Table.ID_6 = Table_6.ID),
Main_Table.ID_7 = Table_7.ID),
Main_Table.ID_8 = Table_8.ID),
Main_Table.ID_9 = Table_9.ID),
Main_Table.ID_10 = Table_10.ID),
Main_Table.ID_10 = Table_11.ID),
Main_Table.ID_11 = Table_12.ID),
Main_Table.ID_11 = Table_13.ID),
Main_Table.ID_11 = Table_14.ID),
Main_Table.ID_12 = Table_15.ID),
AND cust_id = colname
The idea is to get some text values from the sub tables by passing through the relevant ID of the main table to the sub tables ID. To add to the complexity the "cust_id = colname" is a passthrough from a prior page that only brings up a specific record from the main table. Further complexity may come where the two bolded sections are using a single ID from the main table to call from multiple sub tables.
Ideally at the end of this I just want to pull the value from the recordset and drop into the page design. The page is PHP and the database/web server is using WAMP, if that helps?
I feel i'm so close (but i'm probably nowhere near!). Can anyone help me before I lose my hair and develop a nervous tick? Unfortunately, I am still a bit of a novice with these things, so if it's my syntax or a coding issue please could you explain it in noob terms for me?
Thank you in advance!

The database was an access DB of 1 main table and 15 related tables that was then converted to MYSQL. The idea is that it will serve two purposes from web pages setup to point to it;
1) To add records to the main database with dropdowns. Certain data will be shown depending on the dropdown selected.
2) To show a data-only details screen.
The data is complicated survey data and it was decided that the main table would store the variables and the sub tables would store the constants (Between 2 to 6 records) using the ID to link them.
e.g.
Name = Main table.name
Address = Main table.address
Position = Table 2.position
Department = Table 2.Department
etc...
Have tried the AND statement above but the system just times out.
Would it be easier to create multiple recordsets (15 recordsets of 1 main table and 1 sub table) and link it somehow to the cust_id? If so, how would I best set each up so only the relevant fields are pulled from the sub table for each recordset? Or am I being to adventerous and should I just give up and flatten the tables to 1 single table?
Am starting to thin up top with this one! lol!

Recordsets with multiple options - AND, OR If Else and the "Any" Rule

Hi,
Been trying to get this to work for days now... I have a form with drop down lists that feeds through variables to a search page... The Recordset Jobsearch2 shown below works great so long as a user chooses and option that has info in the DB.... ie all fields must be present. I cannot seem to work out how to achieve and Any rule?...
I have had 2 options suggested to me...
a) the code below...
if(isset($searchsector) && $searchsector !== "") {
$query_jobsearch2 .= ' AND Sector LIKE "%' . mysql_real_escape_string($searchsector) . '%"';
putting this in for each option..... but If Im told I have to add this in before the "$jobsearch2 = mysql_query" line... but when I do this the recordset disappears\is deleted...
b) Using an Array and "Implode" - this wouldbe great I'm sure if I had any clue how to do this and what it meant.
MY CURRENT CODE
<?php require_once('Connections/steelbakercouk_473245_db1.php'); ?>

Default value in recordset variable

Hi,
I am using Dreamweaver 8.
I am not sure that I understand the function of the default
value in the variable area of the recordset. I'm using a search box
and sending the result on through the url. If the person types
something that is not in either of the two fields searched, is the
default value supposed to kick in? I have tried entering a value of
something that is actually in the field, but get a broken image
(x)...I'm displaying images.
What I would actually do is to display an error message on a
different page. Is there a SQL statement that could be put after
the search statement such "if not....go to url or
something"? If not, I was thinking of creating a blank
image with wording stating that there was no match.
Current recordset code:
SELECT*
FROM images
WHERE description LIKE %colname% OR picturenum = colname2
ORDER BY picturenum ASC
Name:colname
Type:Text
Default Value: montana (an actual word in the database)
Run-Time Value: $_GET['description']
Name:colname2
Type:Text
Default Value: A091 (an actual image in the database)
Run-Time Value: $_GET['description']
Current code works perfectly thanks to some direction by
David Powers....thanks David.
Any help would be appreciated.
Thanks,
Cliff

The best way to accomplish this is to build the WHERE clause dynamically, or else have a different WHERE clause that you use in these situations. In other words, test the value of the querystring variables and if they are empty, use a different WHERE clause that does not include the address condition.
Also, this question belongs in the app dev forum.

Updateable recordset from a stored procedure

I would like to retrieve an updateable recordset from a stored procedure using the oracle 9.2.0.2.0
oledb provider
I am using the sample code/tables provided from Oracle.
Does anyone have an example or has actually created an updatedable recordset from a stored procedure ?

Assuming your stored procedure is returning a REF CURSOR, it cannot be done. Oracle's REF CURSORS are read only constructs.

How to get an updatable ADODB Recordset from a Stored Procedure?

In VB6 I have this code to get a disconnected ADODB Recordset from a Oracle 9i database (the Oracle Client is 10g):
Dim conSQL As ADODB.Connection
Dim comSQL As ADODB.Command
Dim recSQL As ADODB.Recordset
Set conSQL = New ADODB.Connection
With conSQL
.ConnectionString = "Provider=OraOLEDB.Oracle;Password=<pwd>;Persist Security Info=True;User ID=<uid>;Data Source=<dsn>"
.CursorLocation = adUseClientBatch
.Open
End With
Set comSQL = New ADODB.Command
With comSQL
.ActiveConnection = conSQL
.CommandType = adCmdStoredProc
.CommandText = "P_PARAM.GETALLPARAM"
.Properties("PLSQLRSet").Value = True
End With
Set recSQL = New ADODB.Recordset
With recSQL
Set .Source = comSQL
.CursorLocation = adUseClient
.CursorType = adOpenStatic
.LockType = adLockBatchOptimistic
.Open
.ActiveConnection = Nothing
End With
The PL/SQL Procedure is returning a REF CURSOR like this:
PROCEDURE GetAllParam(op_PARAMRecCur IN OUT P_PARAM.PARAMRecCur)
IS
BEGIN
OPEN op_PARAMRecCur FOR
SELECT *
FROM PARAM
ORDER BY ANNPARAM DESC;
END GetAllParam;
When I try to update some values in the ADODB Recordset (still disconnected), I get the following error:
Err.Description: Multiple-step operation generated errors. Check each status value.
Err.Number: -2147217887 (80040E21)
Err.Source: Microsoft Cursor Engine
The following properties on the Command object doesn't change anything:
.Properties("IRowsetChange") = True
.Properties("Updatability") = 7
How can I get an updatable ADODB Recordset from a Stored Procedure?

4 years later...
I was having then same problem.
Finally, I've found how to "touch" the requierd bits.
Obviously, it's hardcore, but since some stupid at microsoft cannot understand the use of a disconnected recordset in the real world, there is no other choice.

RecordSet to Cusror Conversion Help Needed

Hi,
I have a Perl Code which calls a Stored Procedure in Oracle 8i Database. As you know that you can return Cursors
and other data types back to Perl and not RecordSets. So I am trying to convert a RecordSet to a Cursor. The Stored
Procedure Does some complex computations and then stores the results in a record Set. I need to tansfer the data
from the Record Set back to the Perl Code via a REF Cusror. The only solution that I can think of is Creating a Temp
Table to store the results and then point a Cursor to that and return that Cusror to the Perl Code. Is there any other
way of doing this???. I searched lot of sites/forums, But couldnt find any solution.
You Help will be greatly appreciated :).
Thanks
Rajesh

Hi Rajesh,
i too had the same requirement but using Java Code.
One way to return a Cursor to the code is using a package.
the query which returns the recordset is to be assigned to a ref cursor. For eg.
CREATE OR REPLACE PACKAGE PKG_PLAN AS
TYPE RESULT IS REF CURSOR;
PROCEDURE USERDETAILS2 (
O_RESULT OUT RESULT
END PKG_PLAN;
CREATE OR REPLACE PACKAGE BODY PKG_PLAN AS
PROCEDURE USERDETAILS2(
O_RESULT OUT RESULT
AS
BEGIN
OPEN O_RESULT FOR SELECT DISTINCT US_FIRSTNAME AS UserName,
US_COMPANYNAME AS Company, TBLUSER.US_PRIMARYEMAIL AS EmailId ,
FROM
TBLUSER where
TBLUSER.US_STATUS = 'A' ORDER BY UserName;
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('INSIDE EXCEPTION');
END USERDETAILS2;
END PKG_PLAN;
and in the perl code u will invoke the procedure as
CALL PKG_PLAN.USERDETAILS2(?)
where ? is the out parameter -of type cursor which is to be
registered via perl code.(not sure how it is done in perl)
and after issuing execute command via perl code
get the resultset.
hope u understood it and the above was of help.
Good luck

Scrollable/Read_only ResultSet objects

I am trying to create an instance of a scrollable/read_only ResultSet object with the following code:
Statement stmt = con.createStatement(
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
ResultSet rs = stmt.executeQuery("SELECT * FROM ...");
The Connection object has been made successfully but am getting an AbstractMethodError Exception at line 1.
Can anyone please help me out here.
Thank you.

I don't believe the Oracle driver allows for
read/only. I'll take a look at the Oracle website,
and see if I can verify that.
JoelSorry, I was wrong on this. From the Oracle JDBC documentation, it states that CONCUR_READ_ONLY is valid for the Oracle 8 and Oracle 9 drivers. Are you using classes12.zip or classes12.jar for your Oracle libraries?

I am using JDK 1.3.1 and JDBC 2.0

I use this and works fine for me....let me know how it goes...
ResultSet resultSetMultCond = null;
Statement getMultPartCond = null;
String sqlMultCond = null;
sqlMultCond = "SELECT #PART,#CONDS,COUNT(*) AS MCOUNT FROM MYLIB WHERE #PART = 'A123' GROUP BY #PART,#CONDS ORDER BY #PART";
getMultPartCond = conn.createStatement(java.sql.ResultSet.TYPE_SCROLL_SENSITIVE,java.sql.ResultSet.CONCUR_UPDATABLE);
resultSetMultCond = getMultPartCond.executeQuery(sqlMultCond);

How to change recordset bahaviour to accept dynamic column names in the where clause

Hi
im using php-mysql and i make a recordset and i want to make the column names in the where clause to be dynamic like
"select id,name from mytable where $tablename-$myvar";
but when i do this my i break the recordset and it disappear
and when i use variables from advanced recordset it only dynamic for the value of the column not for the column name
and when i write the column name to dynamic as above by hand it truns a red exclamation mark on the server behaviour panel
so i think the only way is to change the recordset behaviour is it? if so How to make it accept dynamic column names?
thanks in advance.

As bregent has already explained to you, customizing the recordset code will result in Dreamweaver no longer recognizing the server behavior. This isn't a problem, but it does mean that you need to lay out your dynamic text with the Bindings panel before making any changes. Once you have changed the recordset code, the Bindings panel will no longer recognize the recordset fields.
Using a variable to choose a column name is quite simple, but you need to take some security measures to ensure that the value passed through the query string isn't attempting SQL injection. An effective way of doing this is to create an array of acceptable column names, and check that the value matches.
// create array of acceptable values
$valid = array('column_name1', 'column_name2', 'column_name3');
// if the query string contains an acceptable column name, use it
if (isset($_GET['colname']) && in_array($_GET['colname'], $valid)) {
$col = $GET['colname'];
} else {
// set a default value if the submitted one was invalid
$col = 'column_name1'
You can then use $col directly in the SQL query.

Not able to retrive the recordset from oracle stored procedure in VC++

Hi,
I am trying to retrieve the records from the reference cursor which is an out parameter for an oracle 9i store procedure in VC++ application. But it is giving the record count as -1 always. Meanwhile i am able to get the required output in VB application from the same oracle 9i store procedure .
Find the code below which i used.
Thanks,

It can be linked to internal conversion. In some case, the value of internal or extranal value is not the same.
When you run SE16 (or transaction N), you have in option mode the possibility to use the exit conversion or not.
