CASTING in PL/SQL

Can i cast a varchar2 to int in PL/SQL.
I dont want to cast in a select statement.
I want to some thing like
num number;
var varchar2;
num:=1;
var:='asd';
i want to concat these to variables and cast it into a number.
Is this possible ,if yes ,then how

My Oracle ver. still gives a 'invalid number' for the expression! Ah, that's because you need the Super Double Secret
version of Oracle with the Deep Thought option.Or possibly just a text editor???

Oracle.sql.STRUCT cannot be cast to oracle.sql.STRUCT

I met a problem,I use oracle spatial to store geometry,then get it like this:
STRUCT dbObject = (oracle.sql.STRUCT)rs.getObject("shape");
JGeometry geom = JGeometry.load(dbObject);
tomcat 6 told me java.lang.ClassCastException: oracle.sql.STRUCT cannot be cast to oracle.sql.STRUCT

Hi, this is a known problem for most Spatial 10g Java APIs with WLS.
WLS is only certified with 11g DB.
Instead of using Weblogic JNDI Lookup for Datasource, try the following snippet to create your connection/datasource (with Oracle JDBC thin driver):
String databaseUrl = jdbc:oracle:thin:@1.2.3.4:1521:yourdbname
String databaseUser = dbusername
String databasePassword = dbpassword
DriverManager.registerDriver(new OracleDriver());
Connection aConnection = DriverManager.getConnection(databaseUrl, databaseUser, databasePassword);

Javax.sql.rowset.serial.SerialBlob cannot be cast to oracle.sql.BLOB

Hi there,
I'm facing this exception.
My code:
final ReportTemplateAttachment rta = new ReportTemplateAttachment();
FileBlob fb = new FileBlob();
fb.setContentType(attachmentDto.getContentType().getValue());
fb.setCreationDate(sysDate);
fb.setCreationUser(userId);
final SerialBlob blob = new SerialBlob(attachmentDto.getFileVal());//it's a byte[]
//SerialBlob is of type javax.sql.rowset.serial.SerialBlob
fb.setFileData(blob);
fb.setName(attachmentDto.getFileName());
fb.setLastUpdateDate(sysDate);
fb.setLastUpdateUser(userId);
fb.setLength(blob.length());
rta.setFileBlob(fb);and the object rta will be inserted into another object.
The variable of interest in FileBlob hbm is defined as follows:
<property name="fileData" type="blob">
<column name="FILE_DATA" />
</property>where the type blob is oracle.sql.BLOB
If I change the oracle.sql.BLOB to javax.sql.rowset.serial.SerialBlob in the hbm, I can insert but when I try to get the blob back I get a deserialize exception so this change is not an option.
but when I save the main Object (a cascade operation) I get the following exception:
org.springframework.jdbc.UncategorizedSQLException:
Hibernate flushing: could not insert: [pt.sc.data.entities.FileBlob];
uncategorized SQLException for SQL
[insert into WP_ADMIN.file_blob (name, content_type, length, file_data, status, creation_user, creation_date, last_update_user, last_update_date, id)
values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?)];
SQL state [null];
error code [0];
An SQLException was provoked by the following failure: java.lang.ClassCastException:
javax.sql.rowset.serial.SerialBlob cannot be cast to oracle.sql.BLOB;
nested exception is java.sql.SQLException: An SQLException was provoked by the following failure:
java.lang.ClassCastException: javax.sql.rowset.serial.SerialBlob cannot be cast to oracle.sql.BLOBAny light on the subject?
Thanks in advance,

You don't seem to understand the difference between an object model and a database. Hibernate, being an ORM package, works on the object model and will, based on what you request it to do, generate proper SQL statements to get the database part going. But you shouldn't be thinking about databases when using Hibernate; your main focus is the object model. There is no blob, only binary data. Binary data in Java is generally handled through a byte array.
If you want to think in databases where blobs do exist, you should be using JDBC directly, not Hibernate.
(I'm far from being an expert in Hibernate)I would really suggest taking a few hours and reading through the manual. You don't need to be an expert but you should at least know what kind of tool you're working with.

Records and Objects, Cast for PL/SQL Type RECORD and SQL Type OBJECT

Hi seniors:
In my job, we have Oracle 10g, programming with Packages, the parameters are PL/SQL Types,
Example:
PACKAGE BODY NP_CONTROL_EQUIPMENT_PKG
IS
TYPE TR_EQUIPMENT_OPERATION IS RECORD(
wn_npequipmentoperid CONTROL_EQUIPMENT.NP_EQUIPMENT_OPERATIONS.npequipmentoperid%TYPE,
wv_npactiveservicenumber CONTROL_EQUIPMENT.NP_EQUIPMENT_OPERATIONS.npactiveservicenumber%TYPE,
wv_npspecification ORDERS.NP_SPECIFICATION.npspecification%TYPE,
wv_nptype ORDERS.NP_SPECIFICATION.nptype%TYPE,
wn_nporderid CONTROL_EQUIPMENT.NP_EQUIPMENT_OPERATIONS.nporderid%TYPE,
wn_npguidenumber CONTROL_EQUIPMENT.NP_EQUIPMENT_OPERATIONS.npguidenumber%TYPE,
wd_npdevolutionprogramdate CONTROL_EQUIPMENT.NP_EQUIPMENT_STATUS.npdevolutionprogramdate%TYPE
TYPE TT_TR_EQUIPMENT_OPERATION_LST IS TABLE OF TR_EQUIPMENT_OPERATION INDEX BY BINARY_INTEGER;
PROCEDURE SP_GET_EQUIPMENT_OPERATION_LST(
an_npequipstatid IN CONTROL_EQUIPMENT.NP_EQUIPMENT_STATUS.npequipstatid%TYPE,
at_equipment_operation_list OUT TT_TR_EQUIPMENT_OPERATION_LST,
av_message OUT VARCHAR2
IS
BEGIN
SELECT EO.npequipmentoperid,

S.nptype,
EO.nporderid,
EO.npguidenumber,
ES.npdevolutionprogramdate
BULK COLLECT INTO at_equipment_operation_list
FROM NP_EQUIPMENT_OPERATIONS EO,
NP_EQUIPMENT_STATUS ES,
ORDERS.NP_ORDER O,
ORDERS.NP_SPECIFICATION S
WHERE EO.npequipstatid = ES.npequipstatid
AND EO.nporderid = O.nporderid
AND O.npspecificationid = S.npspecificationid
AND EO.npequipstatid = an_npequipstatid;
EXCEPTION
WHEN OTHERS THEN
av_message := 'NP_CONTROL_EQUIPMENT_PKG.SP_GET_EQUIPMENT_OPERATION_LST: '||SQLERRM;
END SP_GET_EQUIPMENT_OPERATION_LST;
END;
Procedures calls other procedures and passing parameters IN OUT defined that PL/SQL Types. The problem appears when the access is through Java. Java can't read PL/SQL Types because only read SQL Types (Types defined in SCHEMA):
CREATE OR REPLACE
TYPE TO_EQUIPMENT_OPERATION AS OBJECT (
wn_npequipmentoperid NUMBER,
wv_npactiveservicenumber VARCHAR2(15),
wv_npspecification VARCHAR2(8),
wv_nptype VARCHAR2(2),
wn_nporderid NUMBER,
wn_npguidenumber NUMBER,
wd_npdevolutionprogramdate DATE
CREATE OR REPLACE
TYPE TT_EQUIPMENT_OPERATION_LST
AS TABLE OF "CONTROL_EQUIPMENT"."TO_EQUIPMENT_OPERATION"
Java can read this SQL Types. The problem is how cast OBJECT to RECORD, because I can't execute that:
DECLARE
wt_operation_lst TT_EQUIPMENT_OPERATION_LST;
BEGIN
SELECT EO.npequipmentoperid,
EO.npactiveservicenumber,
S.npspecification,
S.nptype,
EO.nporderid,
EO.npguidenumber,
ES.npdevolutionprogramdate
BULK COLLECT INTO wt_operation_lst
FROM NP_EQUIPMENT_OPERATIONS EO,
NP_EQUIPMENT_STATUS ES,
ORDERS.NP_ORDER O,
ORDERS.NP_SPECIFICATION S
WHERE EO.npequipstatid = ES.npequipstatid
AND EO.nporderid = O.nporderid
AND O.npspecificationid = S.npspecificationid
AND EO.npequipstatid = an_npequipstatid;
END;
and throws NOT ENOUGH VALUES, and I modified to:
DECLARE
wt_operation_lst TT_EQUIPMENT_OPERATION_LST;
BEGIN
SELECT TO_EQUIPMENT_OPERATION(EO.npequipmentoperid,
EO.npactiveservicenumber,
S.npspecification,
S.nptype,
EO.nporderid,
EO.npguidenumber,
ES.npdevolutionprogramdate)
BULK COLLECT INTO wt_operation_lst
FROM NP_EQUIPMENT_OPERATIONS EO,
NP_EQUIPMENT_STATUS ES,
ORDERS.NP_ORDER O,
ORDERS.NP_SPECIFICATION S
WHERE EO.npequipstatid = ES.npequipstatid
AND EO.nporderid = O.nporderid
AND O.npspecificationid = S.npspecificationid
AND EO.npequipstatid = an_npequipstatid;
END;
Worst is that I can't modify this procedure and PL/SQL Types will survive.
I have create a copy that CAST RECORD to OBJECT and OBJECT to RECORD too.
PROCEDURE SP_COPY_PLSQL_TO_SQL(
an_npequipstatid IN NUMBER,
at_dominio_lst OUT ORDERS.TT_EQUIPMENT_OPERATION_LST, --SQL Type

IF av_message IS NULL THEN
at_dominio_lst := ORDERS.TT_EQUIPMENT_OPERATION_LST(ORDERS.TO_EQUIPMENT_OPERATION('','','','','','',''));
at_dominio_lst.EXTEND(wt_dominio_lst.COUNT - 1);
FOR i IN 1..wt_dominio_lst.COUNT LOOP

How to type cast PL/SQL table to REF cursor?

any one knows how to CAST PL/SQl table to Ref cursor?
eg
procedure some_name(r_out out sys_refcurosr)
IS
type t is table of tab%ROWTYPE;
my_type t;
begin
select * bulk collect into my_type from tab;
r_out := my_type; -- need help here..
end;
it's 10g

ref cursor is pointer to result set. You can not cast to PL/SQL table.
1 create or replace procedure some_name(r_out out sys_refcursor)
2 IS
3 begin
4 OPEN r_out for select * from emp;
5* end;
SQL> /
Procedure created.
SQL> var mycursor refcursor;
SQL> exec some_name(:mycursor);
PL/SQL procedure successfully completed.

How to use count sql statement?

i've never used the count function and i'm not sure how to use it to print it onto a html page...my code is below...
<%
String tot = (String)session.getAttribute("total");
int total = Integer.parseInt(tot);
Class.forName("org.postgresql.Driver");
// create connection url
String URL2 = "jdbc:postgresql://dbhost/ug59sxn";
// pass database parameters to JDBC driver
Connection Conn2 = DriverManager.getConnection(URL2, "ug59sxn", "hupeswop");
// query statement
Statement SQLStatement2 = Conn2.createStatement();
// generate query
String Query2 = "SELECT COUNT(*) FROM userteam WHERE total > '"+total+"'";
// get result code
ResultSet SQLResult2 = SQLStatement2.executeQuery(Query2);
int position = (int)SQLResult2 + 1;
%>

Your Team, <%= session.getAttribute("teamname") %>, are currently lying in position <% out.println(position) %>, with <%= session.getAttribute("total") %> points. 

 Use the shorcuts on the left to visit different sections of the game.
You can change your squad around to prepare for forthcoming games (fixtures can be found in the statistics section),
transfer a player in to your squad to add some depth or replace injured members, or perhaps browse the statistics section to see how your team is doing in the FFL table.

You cannot cast a ResultSet object (or any other object for that matter) to a primitive (such as an int)
Replace the following line of code:
int position = (int)SQLResult2 + 1;with this:
int position = 0;
if(SQLResult2.next())
position = SQLResult2.getInt(1) + 1;
}Additionally I noticed that you have put single quotes around total in the following line:
String Query2 = "SELECT COUNT(*) FROM userteam WHERE total > '"+total+"'";Are you sure that the total column in the userteam table is of string type? If not, you don't need the single quotes.

How to select data from a PL/SQL table

Hi,
I am selecting data from database after doing some screening i want to store it in a PL/SQL table (temporary area) and pass it to oracle reports.
Is there any way to select the data from a PL/SQL table as a cursor. Or is there any other way of holding the temporary data and then pass it back as a cursor.
Regards
Kamal

A PL/SQL "table" is anything but a table. Whoever came up with this term in PL/SQL to describe what is known as dynamic arrays (the correct programming terminology that existed since the 70's if not earlier and what is used in all other programming languages I'm familiar with)... well, several descriptions come to mind and none of them are complimentary.
You cannot "select" from a PL/SQL dynamic array as it is not a table within the Oracle context of tables.
Thus you need to convert (cast) a PL/SQL dynamic array into a temporary Oracle data set/table in order to select from it. This is in general a Bad Idea (tm). Oracle tables and SQL and concurrency controls and all that are especially designed for processing data. PL/SQL arrays is a very simplistic data structure with very limited usage. Why would you want to use that in SQL via a SELECT statement when you can use Oracle tables (or proper temp tables) instead? Besides that, it is also slow to cast a dynamic PL/SQL array into an Oracle SQL data set structure (context switching, copying of memory, etc).
The proper way to use PL/SQL to generate data sets for use via the SQL engine is pipelined table functions.
This is not to say that you should never use PL/SQL arrays and casting in SQL.. simply that you need to make sure that this is the correct and scalable way to do it. And that will also always be an exception to the rule when you do.

Why named parameter can't be used multiple times in PL/SQL block in JDBC

with the following PL/SQL block, when I run int in JDBC, I get an error,
it says, The number of parameter names does not match the number of registered parameters.
if all named parameters are used only once, then my program works fine.
My old program uses Oracle Forms to run the attached PL/SQL block correctly, I just want to run them in JDBC without more efforts, I don't want to rewrite all PL/SQL blocks.
Does oracle driver support this case? why the PL/SQL block can work in Oracle Forms but failed in JDBC?
Can we have an another solutions to avoid rewriting the PL/SQL block to stored procedure?
if I use following SQL:
BEGIN if :q is null then :q := 'X'; else :q := 'Y'; end if; END;
, Using java program:
import java.sql.*; public class RunPLSQLBlock { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL = "BEGIN if :q is null then :q := 'X'; else :q := 'Y'; end if; END;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter("q", Types.VARCHAR); stmt.setString("q", "A"); stmt.execute(); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
in the coding, only "q" registered, I got:
java.sql.SQLException: The number of parameter names does not match the number of registered praremeters at oracle.jdbc.driver.OracleSql.setNamedParameters(OracleSql.java:314) at oracle.jdbc.driver.OracleCallableStatement.execute(OracleCallableStatement.java:10096) at oracle.jdbc.driver.OraclePreparedStatementWrapper.execute(OraclePreparedStatementWrapper.java:5693) at RunPLSQLBlock.main(RunPLSQLBlock.java:28)
now, tried to register 3 indexes, changed fragments are below.
import java.sql.*; public class RunPLSQLBlock { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL = "BEGIN if :q is null then :q := 'X'; else :q := 'Y'; end if; END;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter(1, Types.VARCHAR); stmt.registerOutParameter(2, Types.VARCHAR); stmt.registerOutParameter(3, Types.VARCHAR); stmt.setString(1, "A"); stmt.execute(); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
now error changed to:
java.sql.SQLException: ORA-01006: bind variable does not exist at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:457) at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:400) at oracle.jdbc.driver.T4C8Oall.processError(T4C8Oall.java:926) at oracle.jdbc.driver.T4CTTIfun.receive(T4CTTIfun.java:476) at oracle.jdbc.driver.T4CTTIfun.doRPC(T4CTTIfun.java:200) at oracle.jdbc.driver.T4C8Oall.doOALL(T4C8Oall.java:543) at oracle.jdbc.driver.T4CCallableStatement.doOall8(T4CCallableStatement.java:208) at oracle.jdbc.driver.T4CCallableStatement.executeForRows(T4CCallableStatement.java:1416) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1757) at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:4372) at oracle.jdbc.driver.OraclePreparedStatement.execute(OraclePreparedStatement.java:4595) at oracle.jdbc.driver.OracleCallableStatement.execute(OracleCallableStatement.java:10100) at oracle.jdbc.driver.OraclePreparedStatementWrapper.execute(OraclePreparedStatementWrapper.java:5693) at RunPLSQLBlock.main(RunPLSQLBlock.java:26)
, now tried register only 1 position like below,
CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter(1, Types.VARCHAR); stmt.setString(1, "A"); stmt.execute();
, it says:
java.sql.SQLException: Missing IN or OUT parameter at index:: 2 at oracle.jdbc.driver.OraclePreparedStatement.processCompletedBindRow(OraclePreparedStatement.java:2177) at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:4356) at oracle.jdbc.driver.OraclePreparedStatement.execute(OraclePreparedStatement.java:4595) at oracle.jdbc.driver.OracleCallableStatement.execute(OracleCallableStatement.java:10100) at oracle.jdbc.driver.OraclePreparedStatementWrapper.execute(OraclePreparedStatementWrapper.java:5693) at RunPLSQLBlock.main(RunPLSQLBlock.java:26)
, now let try a OK case, which use all named parameters only once. coding like below, SQL and Java listed below.
BEGIN if :q is null then :r := 'X'; else :s := 'Y'; end if; EXCEPTION WHEN NO_DATA_FOUND THEN NULL; END;
import java.sql.*; public class RunPLSQLBlock { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL = "BEGIN if :q is null then :r := 'X'; else :s := 'Y'; end if; END;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter("q", Types.VARCHAR); stmt.registerOutParameter("r", Types.VARCHAR); stmt.registerOutParameter("s", Types.VARCHAR); stmt.setString("q", "A"); stmt.execute(); System.out.println("Q :" + stmt.getString("q")); System.out.println("R :" + stmt.getString("r")); System.out.println("S :" + stmt.getString("s")); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
, the case give us the following output:
Q :A R :null S :Y
2nd part, I also tried another scheme, to use 'execute immediate', test code attached below, it also have errors.
begin execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out :q, out :r; end;
, Java Code:
import java.sql.*; public class RunDynamicSQL { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL ="begin execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out :q, out :r; end;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter("q", Types.VARCHAR); stmt.registerOutParameter("r", Types.VARCHAR); stmt.setString("q", "A"); stmt.execute(); System.out.println("Q :" + stmt.getString("q")); System.out.println("R :" + stmt.getString("r")); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
, the output is, we can find when parameter 'q' is IN OUT mode, we can't get its final value:
Q :null R :Z
, now I tried my workaround, it works fine by using a temporary variable, now my named parameter is split to 2 roles, one is for IN, another is for OUT, now I can get final out value.
declare q clob; r clob; begin q := ?; r := ?; execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out q, out r; ? := q; ? := r; end;
, my test java code,
import java.sql.*; public class RunDynamicSQL { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL ="declare q clob;r clob; begin q := ?; r := ?; execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out q, out r; ? := q; ? := r; end;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter(3, Types.VARCHAR); stmt.registerOutParameter(4, Types.VARCHAR); stmt.setString(1, "A"); stmt.setString(2, "A"); stmt.execute(); System.out.println("Q :" + stmt.getString(3)); System.out.println("R :" + stmt.getString(4)); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
, the output is expected,
Q :Y R :Z

Hi, thanks for your response, now I see, the named parameter is for stored procedure only, for PL/SQL block we name it placeholder name.
After cast my java.sql.CallableStatement to oracle.jdbc.OracleCallableStatement, I can find setStringAtName,
now, I have only one question:I can't find corresponding methods for registerOutputParameter, how we fetch output value?
I tried to callableStatement.getString("q"); it reports errors, but there are no ordinal binding in my source code, does placeholder names doesn't support OUT mode?
Java:
CallableStatement stmt = con.prepareCall("BEGIN if :q is null then :r := 'X'; else :s := 'Y'; end if; END;");
oracle.jdbc.OracleCallableStatement call = (oracle.jdbc.OracleCallableStatement) stmt;
call.registerOutParameter("q", Types.VARCHAR);
call.registerOutParameter("r", Types.VARCHAR);
call.registerOutParameter("s", Types.VARCHAR);
call.setStringAtName("q", "A");
call.setStringAtName("r", "A");
call.setStringAtName("s", "A");
call.execute();
System.out.println("Q :" + call.getString("q"));
</Java>
<output>
java.sql.SQLException: 不允许的操作: Ordinal binding and Named binding cannot be combined!
 at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)
 at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:146)
 at oracle.jdbc.driver.OracleCallableStatement.getString(OracleCallableStatement.java:2834)
 at RunPLSQLBlock.main(RunPLSQLBlock.java:33)
</output>by the way, in my below-mentioned SQL 'problematic', when my code uses 'execute immediate' and use placeholder names in IN OUT mode, we always get NULL value (i.e. ':q'), but we can get final value of ':r' when ':r' is OUT mode only; now I get a workaround attached in below-mentioned 'my workaround' block, which split the IN OUT roles to 2 parts, it can work now;
It seems that the difference between 'problematic' and 'my workaround' imply that there are something work unexpectedly when the driver process the placeholder names, because 'my workaround' and ':r in problematic case' make sure the 'execute immediate' returned output values correctly, unluckly driver layer can't get return values.
<SQL name = 'problematic'>
begin
 execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;'
 using in out :q, out :r;
end;
</SQL>
<SQL name='my workaround'>
declare
 q clob;
 r clob;
begin
 q := ?;
 r := ?;
 execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out q, out r;
 ? := q;
 ? := r;

Oracle.sql.BLOB and oracle.sql.STRUCT

I'm development a application in Java with oracle, to manage media files. When I try to insert into oracle , I have this problem "oracle.sql.BLOB cannot be cast to oracle.sql.STRUCT" , and I don't know what that can be ..
This is my code , please help with that.. If you have a smaple code of java and oracle to insert media , that will be a great help ..

Clas cast exception in using Clobs

Hi,
          Recently I upgraded from wblogic6.1 SP5 to SP6 and from jdk1.3.1_07 to jdk1.3.1_09.
          After the upgrade, I'm getting a class cast exception when I try to cast a java.sql.Clob to oracle.sql.CLOB. Here is the line of code which throws up the ClassCastException:
          oracle.sql.CLOB message = (oracle.sql.CLOB)cs.getClob(3);
          Where cs is a java.sql.CallableStatement
          I'd appreciate any help or suggestion in this regard
          Dipak Jha

It's hard to tell from the few information you give, but I'd
guess toward a serialization problem.
If some kind of server hold java objects it might decid to serialize the objects and store them on the harddisc for later use. If it tries to deserialize such an object after the class file has changed you might get a class cast exception.
You get this behaviour with Tomcat when you update the class file while tomcat is running.
If your problem is along this line it would explain why it isn't a problem on other machines (no old serializede objects there). And it should go away if you shut down the server remove all kinds of persistant cache it might have and start it up again.
To permanently fix the problem have a look in the java tutorial under serialization. There is some kind of id that you can set to deserialize old objects.

Oracle.sql.BLOB ClassCastException

Hi everyone,
I'm trying to put a serialized Java object into Oracle. I am following the example here: http://www.oracle.com/oramag/oracle/01-may/o31asktom.html
Here is my code:
String sql = "begin " +
      "insert into rdm_logs (datetime, id, machine, ip_addr, action_code, tablename, comments, " +
     "row_before, row_after)" +
      "values (sysdate, ?, ?, ?, ?, ?, ?, empty_blob(), empty_blob()) " +
      "return row_before into ?; " +
"end;";
CallableStatement stmt = connection.prepareCall(sql);
stmt.setString(1, username);
stmt.setString(2, machine);
stmt.setString(3, ip);
stmt.setString(4, action_code);
stmt.setString(5, table);
stmt.setString(6, comment);
stmt.registerOutParameter(7, java.sql.Types.BLOB);
stmt.executeUpdate();
Object o = stmt.getBlob(7);
// output class name here
System.out.println(o.getClass().toString());
// cast to oracle.sql.BLOB
oracle.sql.BLOB blob = (BLOB) o;The system output is:
class oracle.sql.BLOB
java.lang.ClassCastException: oracle.sql.BLOB
As you can see, the System.out gives oracle.sql.BLOB as the object class type, so why does it throw an exception when I cast it to be the same?
Any help would be appreciated.

As you can see, the System.out gives oracle.sql.BLOB as the object
class type, so why does it throw an exception when I cast it to be the same?This can happen if the two BLOB classes have been loaded with two different unrelated class loaders. Even though the names of the classes are the same there are two separate classes.
How to fix this depends... Somehow arrange the JDBC driver to be loaded by the system class loader before any other class loader has a chance to load it?

Oracle.sql.BLOB.setBinaryStream() throws UnsupportedFeatureException

Does anyone know why oracle.sql.BLOB.setBinaryStream(long pos) throws an UnsupportedFeatureException? It seesm to me that if the method were rewritten as:
public OutputStream setBinaryStream(long pos) throws SQLException {
return getDBAccess().newOutputStream(this, getBufferSize(), pos);
... then there would be no reason to throw an exception.
Ideas?
- David

Hi Dave,
I ran into this when I did rs.getBlob(1).setBinaryStream(0) using the ojdbc1_4 driver (without casting to oracle.sql.BLOB). Someone pointed out that I needed to select the BLOB column FOR UPDATE. I did this and now I am getting ORA-01002: fetch out of sequence.
Not sure if I have helped you any...still digging around for the meaning of ORA-01002

Using DB Adapter to execute a custom SQL sequence

Hello everyone, First of all happy 2013
I've done with Jdeveloper using DB Adapter to execute a custom SQL statement, has been very simple, then the code JCA integrate it into OSB OESP PS3, and have successfully deployed, then did a testing from the console of OSB
"Before Configure a DataSource and a Connection Factory for Db Adapter"
I have seen that I have a casting error, but do not understand why, is a single number which I hope to run the following code sequence:
SELECT
MYSEQUENCE.NEXTVAL@DBLINK_EXAMPLE
FROM dual
thanks in advance

Environment WLS 8.1 sp4, Oracle 9i, Solaris 9
I have a need to access the underlying physical db connection so we are using the getVendorConnection() method. On an intermittant basis the connection returned from the connection pool is not an instance of WLConnection so our cast fails.
java.sql.Connection vendorConn =((WLConnection)conn).getVendorConnection();
I believe the true type is weblogic.rmi.SerialConnection.
Is this a known problem? Are their potential workarounds(hopefully through configuration of the connection pool or datasource).
Thanks,
Glen

GlenHi Glen. This will occur if the code that is doing the cast is not in the same JVM as the
WLS server that has the connection. A client JVM can't ever get a direct reference to
a real DBMS JDBC connection that exists only in the server JVM where it was created. RMI
connections are proxies that act as go-betweens from the client to the remote/real
connection and back. The only fix is to run your code in a server, and always have your
pools deployed to the server.
