SQLJ -Context

This seems a very simple example, but it does not work. I want
to specify a context with a SQLJ-statement. It keeps telling
me "Missing equal sign in assignment" at line 23 (#sql
(testContext) { drop table test };).
Can anyone tell me what is wrong?? To me it al seems ok.
Thanks!
import java.sql.*;
import sqlj.runtime.ref.*;
#sql context NewContext;
public class MyClass{
public static void main (String args[]) throws SQLException{
try{
Class.forName("oracle.jdbc.driver.OracleDriver");
catch (Exception e){
System.out.println("driver not loaded");
NewContext testContext = new NewContext( "jdbc:oracle:thin:@
(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(COMMUNITY=TCP.world)
(PROTOCOL=TCP)(Host=atlantis)(Port=1521)))(CONNECT_DATA=
(SID=AT)))"
, "acht114", "vh_cu
rsus", true);
#sql (testContext) { drop table test };
testContext.close();
null

Thanx, it works.
It's weird though, in all the books and articles I have it is
done with normal brackets ().
Now I can go on, great!!

[SQLJ] Context Problem

Hi all,
I am working on Oracle 9i and I compile with the Oracle Console Entreprise Manager.
From an instance baseA, I am looking for getting values from other instance baseB :
Code :
DefaultContext connB = Oracle.getConnection("jdbc:oracle:thin:@ipServer:1521:baseB","user","pwd");
DefaultContext connA = Oracle.getConnection("jdbc:oracle:thin:@ipServer:1521:baseA","user","pwd");
try {
     String result = "";
     #sql [[connB ]] { SELECT lib INTO :result FROM TAB_MESURE WHERE id = 4 };
     RETURN result;
finally {
     connB.close();
     connA.close();
When compiling, this error is displayed
Warning: Impossible de vérifier la clause WHERE. Erreur renvoyée par la base de données : ORA-00942: Table ou vue inexistante (french)
ORA-00942: Table or view doest not exist
- all tns are corectly set up
- Within the same instance,all requests are OK (without using of context)
- I tried diferent connection method wothout success (Oracle.connect, DefaultContext.setDefaultContext, )
Thanks for your help
Merci pour votre aide

SQLJ bug or my problem?

context = new InitialContext();
jdbcURL = (DataSource) context.lookup("jdbc/palocintDS");
conn = jdbcURL.getConnection();
//Create SQLJ context from JDBC connection...
DefaultContext connContext = new DefaultContext(conn);
After creating the connContext above from a DataSource, I can use it for SQLJ SQL queries without error. However, in using any SQLJ Named Iterator for the SQL query, I receive "Invalid Column Index" errors if I use the names themselves in the Iterator (which map to DB column names).
If, instead, I do a .getResultSet() on the SQLJ Iterator object and then access the columns by index with getString(x), getInt(y) etc (ala JDBC) it works fine.
Any ideas?
I'm running this particular application as a Web-Service deployed on Oracle9iAS 9.0.3 from JDeveloper 903.1035.

Thought I'd add the 3 about implied values:
InitialContext context = null;
DataSource jdbcURL = null;
Connection conn = null;

Inheriting Context members from super class

I have a class which extends an abstract class. That abstract
class creates the SQLJ context members (protected members). So
the subclasses can use the contexts. Is there any problem with
SQLJ with this kind of approach. Because I am having strange
problems with this.

...although the question reminds me of some thing that I have always liked and have not seen in any java IDEs: copy the javadoc description of some field to the getter/sett methods for that field. i.e. some thing like,
* This field identifies a customer's unique ID in the database
private int customerID;
* This method returns 'customerID'. [start copy]This field identifies....
public int getCustomerID();

SQLJ Connection Context

Hi,
i was trying to create a SQLJ connection context following the procedure given in the following link.
https://help.sap.com/saphelp_nw04/helpdata/en/70/a19cc472e72c4481172909938578fc/frameset.htm
But i am getting error when i am inserting this sqlj statement inside the class Ctx
public class Ctx
     #sql public context Ctx with (dataSource = "java:comp/env/TMP_PERSISTENCE_EXAMPLE");//here i am getting this error
Error
SQLJ: The ConnectionContext class "Ctx" must not be declared as an inner class of the class "temp.persistence.gettingstarted.dao.Ctx". It may be declared as a static inner class.     Ctx.sqlj     OpenSQLWeb/source/temp/persistence/gettingstarted/dao
could u tell me how i can resolve this.

Hi,
i think you are refering to the sqlj file
with reference to the example its ctx.sqlj
The contents of the file are
<-- Start -->
package temp.persistence.gettingstarted.dao;
#sql public context Ctx with (dataSource = "java:comp/env/TMP_PERSISTENCE_EXAMPLE");
<-- End -->
its not a class file.
If you have installed JDT, you will have the complete working example in 'C:\Program Files\SAP\JDT\eclipse\examples\J2EE_GettingStartedOpenSQL.zip'
Hope that helps.

S.Divakar

Trouble context in SQLJ (please help)

Hi,
I have a problem using "Oracle JDeveloper" as tool to compile sqlj programs.
I have created a connection conn and I want to use this connection with a context. This is the code that I have writed:
import java.sql.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import sqlj.*;
import oracle.sqlj.runtime.*;
import java.util.Vector;

String driver = "sun.jdbc.odbc.JdbcOdbcDriver";
String url = "jdbc:Odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=c:/Oracle/Progetto.mdb";
String username = ";UID=Roberto;";
String password = "PWD=prova";
Class.forName(driver); // load MySQL driver
Connection conn = DriverManager.getConnection(url+username+password);
return conn;
public static void main(String[] args) {
Connection connection1 = null;
try {
connection1 = getConnection1();
#sql context Ctx1;
Ctx1 context = new Ctx1(connection1);
#sql [context] { SELECT id_dip,nome_dip,budget FROM Dipartimento WHERE budget > 1000 };
} catch (Exception e) {
e.printStackTrace();
System.exit(1);
} finally {
try {
connection1.close();
} catch (SQLException e) {
e.printStackTrace();
In particular this peace of code give me a trouble:
Ctx1 context = new Ctx1(connection1);
The word "Ctx1" is always red in JDeveloper!!!! I think I import all the classes that I need....
How can I solve this problem?
Can you try to run this code to look if the text is red in your compiler?
Please help me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thanks!!!

SQLJ+JSP

hello sir
i am using CMP EJB with SQLJ but my problem is when i use this code
i am using this code in jsp page for login purpose
to check login and password in login table
#sql public context DefaultContext;
SafeCon sa=new SafeCon();
ctxx =sa.init();
#sql [ctxx] {
select distinct * from login where acc0=:uname and acc1=:upassword
then it will give the illegal charcter error on # line
and malformed error so can u pls tell me how to solve it
i am using jdeveloper
thanks alot

I will answer myself, so people that has the same problem can see this:
Make a jsp page (callingprogram.jsp) that calls the following file: EXECUTESQLJ.jsp (the file name could be whatever):
-- CALLINGPROGRAM.JSP --
<%@ page contentType="text/html;charset=windows-1252"%>
<HTML>
<HEAD>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=windows-1252">

</HEAD>
<BODY>
Ejecutar un PL/SQL es cuestion de colocar el codigo en JAVA respectivo:
<FORM method="post" action="executesqlj.jsp" onreset="alert('LA FORMA ES REINICIADA')">
Presione el boton --><INPUT type="submit" value="Ejecutar">
<BR>
Para Reiniciar valores presione ---> <INPUT type="reset" value="Reiniciar"></TD>
</FORM>
</BODY>
</HTML>
Then, the file EXECUTESQLJ.JSP should has a look like this:
<%@ page language="sqlj"
contentType="text/html;charset=windows-1252"
import="oracle.jbo.*,
java.sql.SQLException,sqlj.runtime.ref.DefaultContext,
sqlj.runtime.ConnectionContext,java.sql.Connection,

<HTML>
<HEAD>
<TITLE>

</TITLE>
</HEAD>
<BODY>
<% // Codificacion de Java para llamar el procedimiento.
Oracle.connect(new java2().getClass(), "connect.properties");
<% /* remember creating the file connect.properties in your package directory
The file has to be like this:

Are you using JDK 1.2.1? If yes, then try to use JDK 1.2.2 instead. We have seen JDK 1.2.1 garbage collecting things that are still in scope (very unsafe).
If wiggling your configuration does not help, you'll need to provide more info about your environment and it would be best to get a reproducible test case.
One other note: make sure to finally close the SQLJ iterator not the result set that is being returned. Otherwise you can start leaking cursor handles and/or statement cleanup will not be properly performed.

JDBC/SQLJ Team - Please respond - invalid column type error

Hi, I have posted several messages regarding problems using SQL/J to call out a stored packaged function that returns a ref cursor, but haven't gotten one response. I have yet a new problem with it. JDBC team, please acknowledge!
I change the way I obtain a connection to the database from using the Oracle.connect along with a properties file, to now using a DataSource connection pool. As a result, I am constantly getting a SQLException: Invalid column type error. If I change the call to the stored function to a query in the SQLJ code, it's fine. What's going on??
A previous message I wrote stated I was constantly getting a "closed statement" error when I tried to call the next method of the iterator. I corrected this by removing the finally clause in the generated JDBC code that released the execution context.
Again, the environment is JDK1.2.2, SQLJ 8.1.6 SDK, JDBC 8.1.6 thin, all on NT.
Thanks
David

I am getting the same error message - Invalid Column Type. I am creating a Default Context by calling Oracle.getConnection(connection) passing in an instance of my own connection class that basically delegates to the OracleConnection. We wrapped the Connection so that we could trap and recover from lost database connections.
My environment is Solaris 2.6, Oracle 7.3.4 with Sqlj 8.0.5.
Thanks!

SQLJ use in Web Dynpro

Dear All.
How can i use my SQLJ and other helper classes (DB engine) in Web Dynpro? Where can i create the connection context? Is it possible, to use java relational persistence in Web Dynpro without EJB model?
Best Regards, Andrey.

Hi Andrey,
you should wrap your SQLJ related classes behind some EJB module project and another application project. You can create the Connection Context class and other SQLJ classes just by saying File>New>Other>Persistence>SQLJ Source. So first create your connection context class there and llok up for the Datasource alias as defined in your application.xml file in your application project. Later on in the business methods of your session bean you can access these sqlj helper classes for processing ad access the business methods from web dynpro through EJB project reference or local web service model.
For relational persistence you can use JDO if you dont want to use EJB CMP. Though for JDO, there are no wizards in NWDS for creating the .map or .jdo files. So you have to create these files by your own and have to take care of syntactical errors as in any xml.

SQLJ error in stored procedure

Okay I'm kind of new to this stuff so this is probably an easy
question but I can't fix my current problem. Know I have been
creating and compiling several java stored procedures in my
oracle 8.1.7.0.0 enterprise edition database. So far everything
is create I have created about a dozen and done all of their
call specs and everything works without a hitch.
The problem I have came into being when I tried to create a
stored procedure that uses SQLJ. When I create my stored
procedures I compile my java code straight into the database
using the
CREATE OR REPLACE AND COMPILE JAVA SOURCE named "myClass" AS
source
this has always worked from me except when I place my
#sql ; lines at which point it issues a the following error
SP2-7034 : unknown command beginning
at which point is it ignores the line of code and continues to
compile my java source. Does this mean the SQLJ is not enabled
in my database or what? I have checked out the SQLJ developer’s
hand book and it did not help me with this problem. Oh please
wont some wise oracle god help me!

i am creating the collection in my Stored procedure it is giving me this error

error
PL/SQL: ORA-00942: table or view does not exist
please tell me this why this happeningcouple of things...
context switching - Your second 'select visit_id' query is actually parsed outside plsql, in the 'sql engine'. This sql engine has no knowledge of what v_numbers is, it's expecting an actual table name but it can't find anything called v_numbers in it's metadata. So it bombs out with that error. Google 'context switching plsql' for more info. :o)
- as v_numbers is a collection, you could just loop through the results:
for n in 1..v_numbers.count
loop
dbms_output.put_line(v_numbers(n));
end loop;- as stated above, a 'select' without 'into' won't work in plsql anyway.
- there is a way of getting round the context switch, by creating your Type in sql rather than plsql and 'casting' it to a table. Let us know if you want to know the steps to do it, but try reading up on context switch first.
cheers.

2. Created a Web Project (with servlet & JSP) & addition of Dic project.
3. Creation of Enterprise Project and addition of the above Web project.
