Conversion of java Array to oracle SQL Array while calling Stored Procedure

How java Array can be converted to oracle SQL array while calling Stored procedure with callable statement.
i.e java Array ---> Sql Array in Oracle while setting the datatypes to callable statement arguments.

Send SQL query or call stored procedure, which is best???

hello experts!!
i would like to ask what will be the best implementation on querying a database using Java, send a SQL query(insert into table values...) or call stored procedure(just pass parameters)?? and also in stored procedure does "autoCommit/rollback" applies/make sense??

I searched google for this:
Stored Procedures vs. SQL
and found this useful link:
http://www.karlkatzke.com/stored-procedures-vs-sql-calls/
I thiink you should also read up on other articles based on such google searches
to get other opinions. Also, read the links provided by that article.
Personnally, I think stored procedures should be avoided unless there is a definite
advantage as specified in the above article. Especially not used for CRUD operations.
Also, no matter where you put the SQL, it should be documented. I've seen too many stored procedures that aren't documented.

Error while calling stored procedure from Java

Hi Guys,
How are you everybody? I hope everything is goin fine on your side. I have one issue in PL/SQL while calling below stored procedures from Java.

) and we are getting ora errors while calling this stored procedure from java.
All tab types are declared locally, at package level.
Here is error which occur while calling this sp:

Exception while calling stored procedure in SQL server

Hi,
I run into a problem while calling a proc in SQL server. I am using a database control to do so. The proc returns a integer. This is the first time I use SQL server. Any thoughts? Thanks in advance.
My method call is:
int createAccount(SQLParameter[] param)
The sql is:
{call espsiCompany(?, ?, ?)}
The error is:

Hi. That's not the signature of the procedure. What I'd like to see is
the SQL used to create the procedure, eg:
create procedure myProc @foo int, @bar varchar(30) ....
as
begin
end

JDBC SQL Server Channel Calling Stored Procedure Won't Return Result Set

Good afternoon, Experts
We're calling a stored procedure in a sender communcation channel. I can perform any SQL SELECT statement here, but for some reason when I execute the SP (EXECUTE StoredProcedureName) The Adapter Engine returns the following:
Database-level error reported by JDBC driver while executing statement 'DECLARE @UpdateRecords bit SET @UpdateRecords = 0 EXECUTE ExportToSAP @UpdateRecords'. The JDBC driver returned the following error message: 'com.microsoft.sqlserver.jdbc.SQLServerException: The statement did not return a result set.'. For details, contact your database server vendor.
Even stranger yet is is that this works just fine on our PI-DEV system. I created an identical communication channel connecting to the same database with the same UID and PWD and it won't work in PI-QAS.
Any help/ideas you could share would be greatly appreciated!!!
Thanks,
Chad

Hi Chad.
Normally, itu2019s a problem with your procedure. The Store Procedure is wrong and something is different between your DEV environment and QAS environment.
Try to ask to DB team check it.

Bruno

Taking control back while calling stored procedure using java programme

I have stored procedure to load data. This procedure is invoked by java program.
The stored procedure take around 10 to 15 minutes to do complete loading of database. I want to write stored procedure when it starts loading of database at the same return the control to calling java programme so that java program can do other operation i.e. java program can not wait for control back from stored procedure.
In short stored procedure runs in background and return control back to java program when stored procedure is invoked. Is it possible then How we can achieve this.

U can acheive this using Java Threads. Create a thread submit this loading job. Once you submit the thread, you will get the control back to do other stuff.

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.

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.

Problem Encountering in oracle.sql.ARRAY type

Hi,
i am using one stored procedure to get a set of records.
i am getting it by mapping those things with java.sql.Array. And after that i am getting the values as ResultSet from that Array. The same thing is working fine in Windows platform. If i posted those thing into Unix - AIX, i am facing an ArrayIndexOutofBoundsException while getting ResultSet from oracle.sql.ARRAY class. I checked out ARRAY instance.it is not null. Both Application and Database are same except O.S.
Can Anybody help me. I need it imm.
Thanks in Advance
Regards
Eswaramoorthy.G

Hi
Did you ever figure out what the problem was with this? We have a client that is experiencing the same problem on AIX but we cannot reproduce using their database running under NT nor Sun. Any information would be appreciated. You can respond directly to [email protected]

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.

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.

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
