Passing a pl/sql "array" to JDBC

I have a PL/SQL table (index by binary_integer) and I want to pass the values through an OUT parameter to a external java application. But while we have tried declaring my table as a index by table, as a nested table and a varray, the Java gets the error of "wrong number or type of parameters passed to procedure"
Can someone help me out with an example of how to get "array" like data from PL/SQL to java?
Thanks

Hi David
As of now, PL/SQL tables are not supported by the jdbc drivers(both thin and OCI). Oracle plans to support them in their next release.
I would be interested in knowing how you succeeded in handling this as we faced similar problems.

Probably the Oracle has compiled OC4J with other version of this library.

Problem passing oracle.sql.ARRAY to Oracle

I am having ClassCastException when I try to pass a oracle.sql.ARRAY to a Oracle Package.
Here is my code:
PreparedStatement stmt = null;
String strArray[] = { "1,2,3,4,5" };
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor( "TEST_PAC_1.TEST_COLL_2", dbConnection );
//encounter Exception on the line below.
ARRAY array_to_pass = new ARRAY( descriptor, dbConnection, strArray );
String queryStr = "begin TEST_PAC_1.TEST_PROC_2(?); end;";
stmt = dbConnection.prepareStatement(queryStr);
stmt.setArray( 1, array_to_pass );
stmt.execute();
I understand that oracle.sql.ARRAY has been replaced by weblogic.jdbc.vendor.oracle.OracleArray in Weblogic.
MY QUESTION IS: HOW DO I INSERT MY STRING ARRAY INTO THE OracleArray and pass it to the plsql.
Really frustrated searching through the forums for the whole day,
Thanks,

Try this if you are at weblogic 8.1:
Connection con = getConnectionFromDataSource();
Connection vendorConnection = ((WLConnection)con).getVendorConnection();
// use direct oracle connection.
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor( "TEST_PAC_1.TEST_COLL_2", dbConnection );
vendorConnection.close();
Beware that you should be very careful as you are going to use a direct vendor
connection.
The better aproach is to pass the string array as a delimited string to your storad
procedure and parse it in the SP - then you don't have to mess up with vendor-specific
handling.
Hope this helps.

Creating my Oracle connection works fine ... code as follows:
Context ctxt = getInitialContext();
DataSource dataSource = (DataSource) ctxt.lookup(poolName);
Connection conn = dataSource.getConnection();
OracleConnection oracleConn = (OracleConnection)((WLConnection)conn).getVendorConnection();
I also have reviewed documentation:
http://e-docs.bea.com/wls/docs81/jdbc/thirdparty.html. In section 'Using OracleStruct Extension Methods' it highlights that
java.sql.Struct struct =(weblogic.jdbc.vendor.oracle.OracleStruct)(rs.getObject(2));
None of the documentation actually mentions oracle.sql.STRUCT. For Weblogic to truely provide support for Oracle it needs an easy way of converting to this data type. At present I cannot interact with Oracle APIs until I can create an oracle.sql.STRUCT.

PL/SQL array passed to SQL IN

Hi,
I have a PL/SQL array which type is defined like this:
create or replace type type_id_array as table of number(6, 3);
then i create a variable and initilaize:
var_1 type_id_array;
var_1 := .....
then i have a select statement.
select * from table t where t.id in(var_1)
That's it, i want to use the array in an SQL in. This seems not possible.
Can you explain why? Any alternate solutions?
Thanks

Can you explain why? Any alternate solutions?SQL supports set commands specifically for arrays (in addition to the using the TABLE() method mentioned). For example:
SQL> create or replace type TNumbers is table of number;
2 /
Type created.
SQL>
SQL> declare
2          numList TNumbers;
3          cnt     integer;
4 begin
5          numList := new TNumbers(1,2,3,4,5,6,7);
6          select
7                  count(*) into cnt
8          from    user_objects
9          where   TNumbers(object_id) member of numList;
10          DBMS_OUTPUT.put_line( 'cnt='||cnt );
11 end;
12 /
cnt=0
PL/SQL procedure successfully completed.Obviously there are performance considerations when using arrays/collections in SQL. So before choosing a method, evaluate the performance.

Oracle.sql.* with JDBC drivers 8.0.5

the oracle.sql package is not included in my JDBC driver file classes111.zip given for oracle data server version 8.0.5.
I would like to use the oracle STRUCT and ARRAY type for calling PL/SQL stored procedures taking STRUCT objects in arguments.
Are the JDBC drivers 8.1.* compatible with the oracle data server 8.0.5 (if I only use the STRUCT or ARRAY types)? Is it a way for passing ARRAY of VARCHAR2 values to PL/SQL stored procedure with the oracle 8.0.5 JDBC driver?
thanks

Unfortunately, these classes (oracle.sql.STRUCT and oracle.sql.ARRAY) are not compatible to 8.0 database. There is server format changes between 8.1 and 8.0, and JDBC driver only supports the 8.1 format.
Please upgrade your database to 8i.

Looking at the ARRAY.toBytes() method:
public byte[] toBytes()
throws SQLException
synchronized (getInternalConnection())
return this.descriptor.toBytes(this, this.enableBuffering);
..., it synchronizes on the following method (getInternalConnection() -> getPhysicalConnection()):
oracle.jdbc.internal.OracleConnection getPhysicalConnection()
if (this.physicalConnection == null)
try
this.physicalConnection = ((oracle.jdbc.internal.OracleConnection)new OracleDriver().defaultConnection());
catch (SQLException localSQLException)
return this.physicalConnection;
defaultConnection() does the following:
public Connection defaultConnection()
throws SQLException
if ((defaultConn == null) || (defaultConn.isClosed()))
synchronized (OracleDriver.class)
if ((defaultConn == null) || (defaultConn.isClosed()))
defaultConn = connect("jdbc:oracle:kprb:", new Properties());
return defaultConn;
So there's synchronizations on the connection instance and OracleDriver.class object... I can't see how this can deadlock. To get to the point of needing the lock on OracleDriver.class, the thread would already have the lock on the connection instance.... clearly I'm missing something.
Thanks

Welcome to the forum. If you want help, at least try to think where to post a question and look for a forum that matches the topic. Lets examine what you have:
- its Weblogic, so if you would ask a non-programming related question anywhere it would be in the Weblogic forum
- HOWEVER, if you check the top of the stacktrace, you'll see that the problem stems from the JDBC driver, so a JDBC related forum would be a closer match
For future reference, Weblogic specific questions should go here: https://forums.oracle.com/forums/category.jspa?categoryID=193
and JDBC/OJDBC driver related questions should go here: Java Database Connectivity (JDBC)
Final tip: use \ tags to post code so it is readable.

How to create oracle.sql.array

I need to create an oracle.sql.array to pass in my custom objects array to the database. I know you can create it using the ArrayDescriptor class but the problem with that is the connection object is need.
I am using the writeSql() method of the SQLData interface. I therefore dont have the connection object. Any ideas?

haha
you misunderstand. i have in my code:
<code>
 // update the organisation
 public boolean setOrganisation(Organisation pOrg) {
 Organisation org = pOrg;
 OracleCallableStatement callStat = null;
 Connection conn = null;
 boolean OK = false;
 try {
 conn = getConnection(getUserName());
 pOrg.setConnection(conn);
 callStat = (OracleCallableStatement) conn.prepareCall("{call p_cmt.update_organisation(?)}");
 callStat.setObject(1, org);
 callStat.execute();
 OK = true;
 } catch (Exception e) {
 logger.severe("error writing organisation with id " + org.getId() + ". " + e);
 } finally {
 cleanUpConnections(conn, callStat);
 return OK;
</code>
This writes the object organisation to the database. Now in the class organisation i have the following method which is called automatically when writing the organisation object to the database:
<code>
 public void writeSQL(SQLOutput p_stream) throws SQLException {
 p_stream.writeInt(id);
 p_stream.writeObject(country);
 if (finIndexArr == null)
 finIndexArr = new ListElement[0];
 ArrayDescriptor af = ArrayDescriptor.createDescriptor(
 ObjectMapper.elementList, conn);
 ARRAY arr = new ARRAY(af, conn, finIndexArr);
 p_stream.writeArray(arr);
</code>
The problem is the last bit. To put the finIndexArr into an array i need the connection object. So i have to pass into the organisation object the connection object which seems unneccessary and pointless to me. I was just looking at an alternative way of creating the array without the need of the connection object. Since the setOrganisation() above has the connection to the database i dont see why i need to specify it in the array as well

Returning arrays using JDBC 2.0 and JDK 1.2.2

I am able to return a varray from an PL/SQL stored procedure to a Java program using the Oracle JDBC 8.1.6 driver classes (oracle.jdbc.driver.* and oracle.sql.ARRAY). I want to avoid using the Oracle specific classes to do this and instead just use the standard JDBC 2.0 classes and JDK 1.2.2. Will I still be able to access the varray returned by the PL/SQL SP or am I forced to use the Oracle classes?
Why I ask this is because the Java code needs to be usable from a Netscape Application Server 4.0/iPlanet Application Server 6.0 servlet or java class. NAS 4.0 uses the JDBC 2.0 classes but I cannot use the Oracle JDBC 8.1.6 classes since NAS 4.0 requires the Oracle 8.0.5 client. iAS 6.0 provides a JDBC 2.0 type 2 driver and uses the Oracle 8.1.5 client but does not support arrays, i.e. CallableStatement.getArray(), ResultSet.getArray(), etc. are not supported.

Java.sql.SQLException: Internal Error while using oracle.sql.ARRAY.getArray

Hello All,
Here is the issue description. Our application uses Oracle Object Types and LIST. We deployed our application on QA environment which has Oracle 10g. Application runs fine...no issues. Now we moved to UAT. UAT environment is same as QA environment and DBA have created replica of QA database.
Now WAR file which works fine with QA database , somehow doesnt work with UAT database. Application throws following exception when code tries to call getArray() on java.sql.Array.
We tried to point UAT weblogic to QA database and it worked fine.....but when we point UAT weblogic to UAT database , we get following exception. So we know that this is a database issue.
DBA claims that QA env database and UAT env database are same.
Can anybody please tell me what wrong here? What setting is not done on UAT database which is done on QA?

This can happen if you use the oracle.sql.ARRAY class with WebLogic.
WebLogic wraps oracle.sql.ARRAY with its own class (i.e. weblogic.jdbc.wrapper.Array_oracle_sql_ARRAY). The easiest solution is to replace oracle.sql.ARRAY with the JDBC standard java.sql.Array.
<PRE class=jive-pre><CODE class="jive-code jive-java">Object[] items = (Object[])array.getArray();
if (items.length > 0) {
for (int i = 0; i < items.length; i++) {
Object arrayItem = items;
}
}
</CODE></PRE>
The array object is a java.sql.Array. Here no unwrapping of the WebLogic wrapper is needed.
If you absolutely need the oracle.sql.ARRAY class than you must use an unwrap API on the WebLogic wrapper class.
<PRE class=jive-pre><CODE class="jive-code jive-java">if (object instanceof weblogic.jdbc.wrapper.Array)
array = (ARRAY) ( ((weblogic.jdbc.wrapper.Array)object).unwrap(Class.forName("oracle.sql.ARRAY")) );
else
array = (ARRAY) object;
</CODE></PRE>
Here, array is an oracle.sql.ARRAY. Try to see if this <A class=bodylinkwhite href="http://www.software-to-convert.com/3gp-conversion-software/3gp-to-myspace-video-software.html">helps</A>. Good luck.
Thanks for your explanation! It's very valuable, It is exactly what I need, I understand this part.

If i use cs.registerOutParameter(4, Types.ARRAY, "SCHEMA_OWNER_NAME.ISSUESECTION_LIST"); Then i wont be getting the error.
COULD ANYONE LET ME KNOW THE WORK AROUND OTHER THAN THE ABOVE SOLUTION LIKE ADDING THE OWNER SCHEMA NAME WITH THE USER DEFINED COLLECTION TYPE.

There couold be two reasons:
1) it depends how u have defined type. if ISSUESECTION_LIST is defined in type SCHEMA_OWNER, then you have to call this ways only 'SCHEMA_OWNER_NAME.ISSUESECTION_LIST'
2) You might have defined using schema_owner_name like scott.<TYPE_NAME>. if its so, then drop it and again define type without using schema owner.
For detail help post your type declaration.

Java.sql.SQLException: Internal Error with oracle.sql.ARRAY getArray()

hi,
I am having having problems with the getArray() of oracle.sql.ARRAY.
Here are the details:
Oracle Database - 9.2.0.6. The JDBC driver used -10.2.0.1 jar.(the latest available).
I am calling a stored procedure from java, that has out param as a collection (VARRAY) of a user defined type.
The stored procedure works fine, if the user/schema used to connect,contains actual type, and i am able to extract the user defined object from the oracle.sql.ARRAY, via getArray().
But if i use a different user to connect which has public synonyms and execute rights to the actual type, i get the following error:

The problem is happening because we have 2 different users to connect to the database. one is the dba user, which contains all the types, packages and other one the application user, which we are supposed to use, to connect via java. This application user does have access to types via public synonym, but it gives the above mentioned error.
Please help :(.
Regards,
Gaurav.

Hi avi,
Even I am getting the same error inspite of preceding the type name with the same user who has created the type.
It has displayed the array length.When I am trying to fetch each array, I am getting the error.
ARRAY simpleArray = (ARRAY) cs.getObject(3);
System.out.println("Array is of length " + simpleArray.length());          ********************** The above stmt prints 2 records ******************
But it goes to exception in the foll stmt..
Object [] objArrStructArray = null;
try{
     objArrStructArray = (Object[]) simpleArray.getArray();
}catch(SQLException e){
     e.printStackTrace();
Do u know abt this?
The foll is the error which I am getting.

NullPointer from constructor of oracle.sql.ARRAY

This is a strange one, I'm hoping someone has seen this before.
I'm seeing a nullpointer exception from the contructor of ARRAY(ArrayDescriptor, Connection, Object)
This occurs when I'm trying to make a call from an application module to a stored procedure with custom database types.
This seems to work fine in the embedded OC4J instance but fails when deployed to an application server on linux. The version is 10.1.2.
thanks for your help.

Avi, thanks for your response. The connection is obtained from a BC4J appmod, which ultimately comes from a pooled datasource.
When I look at the implementation class in the embeded OC4J environment it is com.evermind.sql.OracleConnectionBCELProxy__com_evermind_sql_OrionCMTConnection__SQLBCELProxy. The call to ARRAY works in this environment.
On the application server the runtime implementation of the connection is com.evermind.sql.ConnectionBCELProxy__com_evermind_sql_OrionCMTConnectionFinalize__SQLBCELProxy. This fails with the exception in the original post.
In both environments I can successfuly cast to an OracleConnection so I'm pretty sure both implementaion classes are subclasses of OracleConnection.
Both environments are 10.1.2.
thanks for your help so far.

Errors using weblogic sql driver: "No JDBC connection can be made because the transaction state is marked rollback"

One of our customers starts to encounter this error message recently.
We checked our log files. It seems that the error happens when
to obtain a jdbc connection. Have anyone seen similar problems
and knows how to fix it? thanks in advance.
We are using weblogic server 6.1sp2, and weblogic sql type 4 driver.
The functions that invoke the jdbc calls are stateless session bean
methods with their transaction attributes marked as Required.
There is no nested calls of these methods.
A partial stack trace we obtained is as following:

Joe,
We got the exact same error message. The error came after we got theJDBC connection,
and trying to create statement off it.
It occurs intermitently when we are running another standalone JAVAapp to do
some end of day work, which results in the DB Server being very busy(90+%CPU
usage) for about 5 minutes. We see a surge of requests to the WLSJDBC Connection
pool. This would sometimes result in all our subsequent DB requeststo fail and
lead to a crash.
We are using WLS6.0SP1. I do not think there's a 30 seconds wait leadingto a
connection timeout that caused this(rather it is the end effect).
Can you give us a more detailed explanation? Is there a miscommunicationbetween
our DB(Sybase12) and WLS?Hi. It looks to you like it's after you get the connection, but really
it's when the server is
gettng the pool connection. For performance/synchronization reasons we
do a clever
delay: When your code asks for a pool connection we quickly give you
the pool wrapper,
but we delay actually reserving the real underlying DBMS connection until
your first
real need for a connection, at your first JDBC call, such as createStatement()
etc.
It is while waiting for a pool connection long enough for the transaction
coordinator
to have timed you out before you ever get a chance. It's nothing to do
with the
DBMS or even JDBC, I believe. I think the weblogic server either has
too few execute-threads
and/or too few CPU cycles to do the work load.
Okay, so there's a lazy initialization of the connection.
From reading our log I believe our failur is immediate rather
than waiting for 30+ seconds(the default setting) from the DB,
the timeout occurred later as a result. At the time either because the DB Server
is very busy.
Since we are running WLS6.0 we have only one connection pool,
we have defined a max of 150 threads in the pool. While this
is happening the DB Server is being pinned by an overnight job,
but the WLS Server is not busy at all. The DB and WLS resides
on different physical boxes.
We also have a thread dump from the WLS console when we rebooted the server, it
showed that we are hanging on to the thread & jdbc
connections after these exceptions has occurred instead of releasing them, note
"16083"(~4.5 hours) seconds has passed:
142 116222 Retry rollback request for tx: 'transaction=(IdHash=2963855,Name =
[EJB UserManagerBeanImpl.signalICUserServletHeartBeat()],Xid=30643:8f3838f3709bf53d,Status=Rolling
Back. [Reason = Unknown],numRepliesOwedMe=0,numRepliesOwedOthers=0,seconds since
begin=16083,seconds left=10,ServerResourceInfo[weblogic.jdbc.jts.Connection]=(state=started,assigned=server),SCInfo[server]=(state=active),properties=({weblogic.jdbc=t3://159.55.158.25:8005,
weblogic.transaction.name=[EJB UserManagerBeanImpl.signalICUserServletHeartBeat()]}))'
Scheduled Trigger
So I would argue this problem actually chewed up resources on the WLS server.

ABAP/4 Open SQL array insert results in duplicate database records in SM58

Hi Everyone,
I am testing a file to idoc scenario in my Quality system. When I passed the input file, the mapping executed successfully and there are no entries in SMQ2 but still the idoc wasn't created in the ECC system. When I have checked in TRFC, I am getting the error ABAP/4 Open SQL array insert results in duplicate database records for IDOC_INBOUND_AYNCHRONOUS function module. I thought this is a data issue and I have tested with a fresh data which was never used for testing in Quality but even then I am getting the same error.Kindly advise.
Thanks,
Laawanya

use FM idoc_status_write_to_database to change the IDoc status from 03 to 30 and then run WE14 or RSEOUT00 to change the status back to 03
resending idoc from status 03 ...is a data duplicatino issue on receiving side...why do u need to do that ?
Use WE19 tcode to debug
In we19
1)U can choose your Idoc number in existing Idoc textbox
2)Press execute
3)u will display ur Idoc struct
4)Dbl click on any field then u can modify its content
5)PressStd Outbound Processing Btn to process modified Idoc
Thats it
