Triggers, Stored Procedures and Java

Hi all.
I started developing some useful (at least for me) Java Package, and I'm wondering if I'm doing the right thing.
Let's say that I have a trigger that calls a Stored Procedure that calls a Java Package.
Let's say that the Java Package can be used by more than one Oracle Schema.
So, my question is:
Should I load the package in every Schema ? Or should I load the package in the System (for instance) schema, creating synonyms for it (if possible) ? Or should I create both the package and the Stored Procedure in System, creating synonyms for the procedure ?
I'm a little stuck in this....
Another question : when my trigger fires, it launch the Stored Procedure and, consequently, my Java Package.... At this point, am I in the same transaction of the trigger ? Or the Java Package start a new "subtransaction" ?
Thanks in advance for Your help.
Best Regards
Fabio GRANDE

Do not create anything in the System schema. Create the package and procedure in one schema and create a public synonym that the other schemas can use to access it.
And yes the trigger and anything it executes are all part of the same transaction. As long as none of the procedures are declared as an autonomous transaction, in which case that procedure would be a separate transaction.

Java stored procedures and triggers in lite

Hi
We are using java stored procedures and java triggers in our application for oracle lite database 5.1.
We would like to know whether these procedures and triggers are uploaded or associated with tables or not because triggers are not being fired for the tables.
The question is - how to find the uploaded procedures and triggers in system tables.
We dont find any tables like (all_objects, user_objects) for this in oracle lite system catalogs given in the documentation.
thanks in advance
yugandhar

I don't have much experience with Lite, but I'm running 9i Personal Edition. Any information about triggers can be found in the "ALL_TRIGGERS" view. You will want to filter out any rows where OWNER = 'SYS' unless you created your triggers as SYS. As for procedures and functions, you can see what you have created in the "ALL_OBJECTS" view where OBJECT_TYPE = 'PROCEDURE' or 'FUNCTION', once again filtering out rows where OWNER = 'SYS'. To see the code of any procedure or function, select substr(text,1,80) from ALL_SOURCE where NAME = 'function name' ORDER BY LINE.
Hope this helps!

Java Stored Procedures and Triggers

I want to to use Java stored procedures and triggers within the Oracle 11g XE
So please , someone can help me because i tried but it didn't work
I don't know where is the problem
Thanks !!

WRONG FORUM!
Welcome to the forum but this forum is for Java JDBC questions and issues. Your question should be posted in the SQL and PL/SQL forum

Mark this question ANSWERED and repost the question in the other forum
Before you post review the Oracle Database Java Developer's Guide - it shows how to create Java stored procedures and has example code
http://docs.oracle.com/cd/B28359_01/java.111/b31225/chfive.htm
And in the new post don't just say "I tried but it didn't work". You need to post the code that you tried and what you mean by "didn't work".
If you got any exceptions or errors you need to post a copy of the exact message or error that you are getting.

Java stored procedures and referencing classes

We are referencing to some classes/libraries which are not present in the database. In normal java world, you specify the libraries/classes needed to run your piece of code in the CLASSPATH and that forms part of your complete code.
Can java stored procedures in the database refer to libraries or class files it requires on the file system rather than the database? Is it possible to make this happen?
Thanks

pshiva,
Posting the same question to multiple forums usually doesn't increase your chances of getting an answer, and it just frustrates those wishing to answer you with the result being that any future questions you post may have less chance of being answered -- because of your uncourteous, initial behaviour.
I have answered your other thread:
java stored procedures and referencing classes
In my opinion, that forum (the Database JVM forum) is the most appropriate for your question.
Good Luck,

Can i use Stored procedures and triggers with SDK

hi all
How to use the stored procedure and Triggers with SDK, can i get a sample code

Hi, Salah.
Use "Exec" in your query to run procedures.
SAPbobsCOM.Recordset oRS;
oRS = (SAPbobsCOM.Recordset)pCmp.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset);
oRS.DoQuery ("EXEC YourStoredProcName");
Triggers are not supported in SDK.

How to send a Varying Array param to a PL/SQL Stored Procedure from Java

* I am VERY new to jdbc, and even somewhat new to Java
* I'm using Java 1.5, Oracle 10g.
* I need to call the following PL/SQL Stored Procedure from Java:
procedure setEventStatus
i_deQueueStatus in deQueueStatus_type
*deQueueStatus_type is the following (an array of deQueueStatus_OBJ):
CREATE OR REPLACE TYPE deQueueStatus_OBJ as object
eventID number (20),
dequeuestatus varchar2(20)
CREATE OR REPLACE TYPE deQueueStatus_TYPE IS VARYING ARRAY(500) of deQueueStatus_obj
*I have created a Java object as follows:
public class EventQueueDeQueueStatus
     long      eventID;
     String      dequeueStatus;
     EventQueueDeQueueStatus(long eventID, String dequeueStatus)
          this.eventID = eventID;
          this.dequeueStatus = dequeueStatus;
I have an ArrayList of these.
I need to pass this list to the Stored Procedure. How do I create a java.sql.Array so I can call CallableStatement.setArray to set the parameter? Or do I use something else? I have tried setObject with both the ArrayList and also with a primitive array, but got "Invalid Column Type" both times.
Any help would be greatly appreciated. I just got this task today, and I have to make it work by Tuesday :-( !
Thanks,
Kathy

Kathy,
Search the archives of this forum and the JDBC forum for the terms STRUCT and ARRAY and you can find some sample code on the JDBC How-To Documents page and the JDBC Samples which can both be accessed from this page:

Problem in calling Oracle stored procedure from Java.

I am trying to invoke the Oracle stored procedure from Java. The procedure does not take any parameters and does not return anything. If I call it from SQL prompt it is working perfectly. I am calling it in my program as follows.
callable_stmt=con.prepareCall("{call pkg_name.proc_name()}");
callable_stmt.execute();
The problem is the control-of-flow is getting strucked in the second line I wrote. It is not giving any error also.
Please clarify me what's wrong with my code?
Seenu.

And how long does the stored procedure take to run from your client machine when running it via sqlplus?

Calling stored procedure from Java raises ORA-1722 exception

Hi,
As the title says, when I call the stored procedure from java I got the exception ORA-1722 (invalid number) but I've checked and rechecked my procedure on SQL-Developer and It's alright it works nice and clean !
What's happening? is there something I'm missing?
The way I call the stored procedure is:
    public void execProcedure(String procedure) {
        CallableStatement cs;
        try {
            cs = conn.prepareCall(procedure);
            cs.execute();
        } catch (SQLException ex) {
            Logger.getLogger(Database.class.getName()).log(Level.SEVERE, null, ex);
     where
    String procedure = "{call validateinfo}"I really need help on this, it's frustraiting me 'cause I need to finish a system but this little big problem is killing me ...
Thanks any advice is very welcome :)

Thanks for your help. Haven't tested the SP with a DB access client... which one do you recommend to use?
The SP is the following:
create or replace
PROCEDURE validateInfo IS
var number;
BEGIN
UPDATE temp_desarrollo
SET status = '1';
COMMIT;
// Some string validations ...
//This one just checks if the value of "monto" is a number
//This update goes good
UPDATE temp_desarrollo tmp
SET cve_status = Decode(cve_status, NULL, '15', cve_status||',15')
WHERE IsNumber(tmp.monto) = 'F';
COMMIT;*/
//This one just checks if the value of "monto" is greater than 0
//if not, change de add to cve_status an errorValue
UPDATE temp_desarrollo tmp
SET cve_status = Decode(cve_status, NULL, '14', cve_status||',14')
WHERE (cve_status NOT LIKE '%15%' OR cve_status IS NULL)
AND to_number(tmp.monto) <= 0;
COMMIT;
//More string validations
EXCEPTION
    WHEN OTHERS THEN
      var := SQLCODE;
      insert into excepciones values(to_char(var));
END;I've deleted much code from the SP since I know there's nothing to do with the excepcion, just that UPDATE statement is the one giving me the exception.
If those two UPDATES statements work with the same field (monto) why the first one is succeding and the second one not?
Cheers,
Federico
P.S. the "isNumber" function is as follows, just in case.
create or replace
function IsNumber(val1 varchar2) return varchar2 is
n number := null;
begin
n := to_number(val1,'9999999999999999.99');
    return 'T';
exception
    when others then
      return 'F';
end;

Calling Stored Procedures from JAVA Application

Hi all,
i am using JDeveloper 3.2.2 for creating a DB Application that
uses Oracle8i as DB Server.
One approach of the application is to only use PL/SQL Stored
Procedures to write Data back to the DB.
Some of the stored procedures expect more than 20 parameters.
I want to know if there is a better way to call such a stored
procedure from Java than using a CallableStatement and setting
its 20 parameters.
Another reason why the way above isnt possible for me is that
i need a dynamic way to set the parameters of the stored
procedure.
A solution for that dynamic way i could think of is to get
the information of the stored procedure by using some functions
of DatabaseMetaData and than use this information to map the
parameters with their respective variables in the java
application.
The best argument against this way is that it would be time and
performance consuming.
So could anybody tell me a solution to call PL/SQL stored
procedures from java which is better than doing something like:
String calString = "{Call myStoredProc(";
while(counter < 22) {
params += "?";
if(counter<21) params += ",";
counter++;
calString += params + ")}";
try {
CallableStatement cs = session.prepareCall(calString);
} catch(SQLException ex) { ... }
cs.setString(1, var1);
cs.setString(1, var2);
And that for every Stored Procedure i want to call ?!?
Any help or direction-leading would be really appreciated.
Tank you much.
MfG,
Oliver Bankel

Hi Oliver,
If you your Stored Procedures were in Java and seamlessly
integrated with your Java application would that make your life
easier?
I don't know if this is a practical or acceptable solution in
your environment but it would certainly solve all of your issues
and provide your with a couple of nice advantages. Scalability
and platform independence are just a couple I could think of.
There is a tool called in2j (see http://www.in2j.com) which will
automatically migrate your PL/SQL Stored Procedures into Java.
You can download a copy of the tool and migrate your PL/SQL to
Java with no upfront costs. If you're happy with the generated
Java and want to deploy it, the migration fee falls due - simple.
Hope this helps.

Calling packaged stored procedure from Java

Hi All,
I'm trying to call a stored procedure from Java but I'm having
problems with registrating the output parameter. I'm getting
the error: Conflicting parameters.: sqltype=2003
This is the stored procedure which is located in a package in
the Oracle database:
package Pack_GetAgencyInformation as
Type InfoType is record ( agen_code varchar(3), agen_designation
varchar(30), agen_adresse varchar(60), agen_tel varchar(12) );
function GetAgencyInformation( P_AGENCE VARCHAR )
return Pack_GetAgencyInformation.InfoType
end Pack_GetAgencyInformation;
This is the Java source from where I'm calling the procedure:
//DriverManager.registerDriver (new
oracle.jdbc.driver.OracleDriver());
     Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection
("jdbc:oracle:thin:@164.48.69.125:1521:ventes", "system", "*****
// @machineName:port:SID,
userid, password
CallableStatement cs = conn.prepareCall("{ ? = call
Pack_GetAgencyInformation.GetAgencyInformation( ? )}");
     try {
          cs.registerOutParameter( 1,
oracle.jdbc.driver.OracleTypes.ARRAY);
     } catch (SQLException e) {
          e.printStackTrace();
     cs.setString(2, "001" );
     //ResultSet rset = cs.executeQuery();
The stacktrace:
java.sql.SQLException: Parametertypen conflicteren.:
sqlType=2003
at oracle.jdbc.dbaccess.DBError.throwSqlException
(DBError.java:168)
at oracle.jdbc.dbaccess.DBError.throwSqlException

(OracleCallableStatement.java:220)
at
oracle.jdbc.driver.OracleCallableStatement.registerOutParameter
(OracleCallableStatement.java:350)
at dbAccess.main(dbAccess.java:25)
I think it has to do with the type InfoType which is created in
the Stored Procedure. I'm absolute no Oracle expert and I
prefer not to make changes to the Oracle database. So any
solution in Java is welcome!
BR, H.Rietman

I managed to get it to work only by changing the stored
procedure. I have changed the return type record to a Ref
Cursor type (had to change alot of code for this). It seams
that Oracle JDBC drivers DON'T support the Record type as a
return type.
So the next question is: is it possible to typecast a record
type to a ref cursor type in Oracle. In this way I can easily
change the return type for the stored procedures.

DB2 Stored Procedure from Java-JDBC

Hi All,
I am using DB2 stored procedure which have been written in COBOL. I have two types of stored procedures. First types of stored procedure takes IN parameter and returns OUT parameter. These stored procedures are working fine. The second type of stored procedure takes IN parameter and returns a CURSOR. According to Database team (who wrote these stored procedure) claims that they can see data in a cursor when they test these stored procedure directly in the database. However, when I run these stored procedures from Java code it returns NULL ResultSet. Here is the code:
public SearchResult getAllBenefitHEDType(SearchParameter searchParam) throws DAOException {
log.debug(" getAllBenefitHEDType method - entering ");
HashMap searchParametersMap = searchParam.getHashMap();
SearchResult searchResult = new SearchResult();
String type = (String) searchParametersMap.get(UDFConstant.LOOKUP_SEARCH_TYPE);
HashMap resultParametersMap = new HashMap();
ArrayList resultSetDTO = new ArrayList();
try {
conn = this.getConnection();
conn.setAutoCommit(false);
System.out.println("getAllBenefitHEDType Step 1");
CallableStatement cs = conn.prepareCall("{call TEST.APS003(?)}"); // Stored Procedure with one IN parameter.
cs.setString(1,type);
boolean retVal = cs.execute(); // this should return true if ResultSet is available.. in my case it is returning false.
// I tried with getting the Object
ResultSet rs = (ResultSet) cs.getObject(1); // this should give me a valid result set ... in my case I am getting null
if (rs!=null) {
System.out.println("getAllBenefitHEDType Step 4A Result Set Not Null");
} else {
System.out.println("getAllBenefitHEDType Step 4A Result Set Is Null");
// I tried getting the resultset
ResultSet rs1 = cs.getResultSet(); // this should give me a valid result set ... in my case I am getting null
if (rs1!=null) {
System.out.println("getAllBenefitHEDType Step 4D Result Set Not Null");
} else {
System.out.println("getAllBenefitHEDType Step 4D Result Set Is Null");
while (rs.next()) {
System.out.println("getAllBenefitHEDType Step 5");
LookupDTO lookupDTO = new LookupDTO();
// the following code populate the Lookup DTOs from ResultSet.

A few comments...
1) Creating tables, particularly tables whose names seem to imply that they are temporary tables, on the fly in a stored procedure is a bad idea. That is not the way to work with Oracle, though it is a common practice in other databases like SQL Server. There is undoubtedly a better way to do this in Oracle if you can explain what you're trying to accomplish from a business standpoint.
2) If you are going to use dynamic SQL, you almost always want to use bind variables, not literals. One of the quickest ways to kill an Oracle database's performance is to not use bind variables.
3) As has already been mentioned, assuming FH_INICIO is a DATE column, you need to put an explicit TO_DATE around your strings in order to convert them to dates. Otherwise, Oracle's implicit cast depends on the session's NLS_DATE_FORMAT, which is likely to be different in different client applications and from different client machines.

Oracle stored Procedure and Packages in CR4E

Hi,
I want to use Stored Procedure in CR4E. I don't know how to use Stored Procedures and packages in Crystal Reports for Eclipse. In the data source explorer I can only see the Tables, Views and Stored Procedures but not packages from my Schema and when I can only drag & drop the Tables and Views into the Field Explorer, I can't drag & Drop the Stored Procedures.
I managed to attached the stored procedure from CR studio. I opened the report in CR4E and I can see the stored procedure and can preview the data. When I try to run the report and override the datasource, it throws oracle error saying "ORA-01008: Not all variables bound". When I tried to use the option
DBOptions._doNotVerifyDB
while replacing connection I get the this error

Please advice if Stored procedures and packages are supported in CR4E ?

Hi, Jack76,
According to the [CR4E Release Notes|http://help.sap.com/businessobject/product_guides/cr4E/en/cr4e_relnotes_en.pdf] (available from the [CR4E Download page|http://www.businessobjects.com/campaigns/forms/downloads/crystal/eclipse/datasave.asp]), stored procedures are supported, as long as they don't use parameters that need null values.
I don't see any references to packages.

Passing data from Oracle stored procedures to Java

We're going to write a new web interface for a big system based on Oracle database. All business rules are already coded in PL/SQL stored procedures and we'd like to reuse as much code as possible. We'll write some new stored procedures that will combine the existing business rules and return the final result dataset.
We want to do this on the database level to avoid java-db round trips. The interface layer will be written in Java (we'd like to use GWT), so we need a way of passing data from Oracle stored procedures to Java service side. The data can be e.g. a set of properties of a specific item or a list of items fulfilling certain criteria. Would anyone recommend a preferable way of doing this?
We're considering one of the 2 following scenarios:
passing objects and lists of objects (DB object types defined on the schema level)
passing a sys_refcursor
We verified that both approaches are "doable", the question is more about design decision, best practice, possible maintenance problems, flexibility, etc.
I'd appreciate any hints.

We're going to write a new web interface for a big system based on Oracle database. All business rules are already coded in PL/SQL stored procedures and we'd like to reuse as much code as possible. We'll write some new stored procedures that will combine the existing business rules and return the final result dataset.
We want to do this on the database level to avoid java-db round trips. The interface layer will be written in Java (we'd like to use GWT), so we need a way of passing data from Oracle stored procedures to Java service side. The data can be e.g. a set of properties of a specific item or a list of items fulfilling certain criteria. Would anyone recommend a preferable way of doing this?
We're considering one of the 2 following scenarios:
passing objects and lists of objects (DB object types defined on the schema level)
passing a sys_refcursor
We verified that both approaches are "doable", the question is more about design decision, best practice, possible maintenance problems, flexibility, etc.
I'd appreciate any hints.If logic is already written in DB, and the only concern is of passing the result to java service side, and also from point of maintenance problem and flexibility i would suggest to use the sys_refcursor.
The reason if Down the line any thing changes then you only need to change the arguments of sys_refcursor in DB and as well as java side, and it is much easier and less efforts compare to using and changes required for Types and Objects on DB and java side.
The design and best practise keeps changing based on our requirement and exisiting design. But by looking at your current senario and design, i personally suggest to go with sys_refcursor.

Need coding support for Accessing MYSQL stored procedure from java

Hi every one,
I need coding support for accessing Mysql stored procedure from java and JSP.
Please help me

You'd better have a recent version of MySQL, because earlier ones didn't support stored procs.
If your MySQL and driver support stored procs, maybe you just need a JDBC stored proc tutorial.
