Callable statement

i have some sql query to execute. so i save the query in a stored procedure. the stored procedure has no param. my query is like this:
create procedure [proc1]
as
select ... into #temp1 ...
select ... into #temp2 ...
select ... into #temp3 from #temp1 ... #temp2
update #temp3 ...
select * from #temp3
go
and my java code is like this:
   // after get connection.
   CallableStatement cs = con.prepareCall("proc1");
   ResultSet rs = cs.executeQuery();
   while (rs.next()) {
   // ...but it throw SQLException with message "NO RESULT SET WAS PRODUCED."
my question is how to get resultset that hold #temp3 record?

You should test your stored procedure first in a regular sql window first e.g. SQLServer Query Analyzer.
Your code should be ok if an empty resultset is returned so you need ensure that the stored procedure is doing what you expect.
You could consider using CallableStatement.execute() then CallableStatement.getResultSet() which returns null if there is no resultset (if not returning a resultset is expected behavior)

Using A callable statement in java

Hi all im trying to get results back from the database using a callable statement the problem is that it is placing / infront of single quotes.I need to get rid of this because it's not returning anything
here is my code
CallableStatement statementOne;
statementOne = ComparitiveAnalysisGUI.conn.prepareCall("{call graphProc(?,?,?,?,?,?,?)}");
statementOne.setString(1,"\"date_format(calldate, '%Y-%m-%d H:59:59'),avg(billsec)\"");
statementOne.setString(2,"Clovercdr");
statementOne.setString(3,start);
statementOne.setString(4,end);
statementOne.setString(5,"Boksburg");
statementOne.setString(6,"\"billsec > 0 and Network = " + network + "\"");
statementOne.setString(7,"\"date_format(calldate, '%Y-%m-%d %H:M:S')\"");
System.out.println(statementOne.toString());
rs = statementOne.executeQuery();
the result of the println is
com.mysql.jdbc.CallableStatement@ec4a87: CALL graphProc('"date_format(calldate, \'%Y-%m-%d %H:59:59\'),avg(billsec)"','Clovercdr','\'2006-03-14 00:00:01\'','\'2006-03-14 23:59:59\'','Boksburg','"billsec > 0 and Network = \'SAMobile\'"','"date_format(calldate, \'%Y-%m-%d %H:M:S\')"')
as you can see quite a mess please help if you can get the statement to look as follows
CALL graphProc("date_format(calldate, '%Y-%m-%d %H:59:59'),avg(billsec)",'Clovercdr','2006-03-14 00:00:01','2006-03-14 23:59:59','Boksburg',"billsec > 0 and Network = 'SAMobile'","date_format(calldate, '%Y-%m-%d %H:M:S')")
thanks Brian

Ok in order to understand why I did what I did parhaps it would be best if you saw my Stored procedure
create procedure graphProc(col varchar(100),company varchar(20),startTime datetime,endTime datetime,branchName varchar(20),andSection varchar(200),groupSec varchar(100))
BEGIN
SET @stmt := CONCAT("SELECT ",col," from ",company," where calldate between '",startTime,"' and '",endTime,"' and branchName = '",branchName,"' and ",andSection," Group by ",groupSec);
PREPARE stmt1 from @stmt;
EXECUTE stmt1;
the call is for example
call graphProc("date_format(calldate, '%Y-%m-%d %H:59:59'),avg(billsec)",'Clovercdr','2006-03-01 00:00:01','2006-03-14 23:59:59','Boksburg',"billsec > 0 and date_format(calldate, '%k') BETWEEN 7 AND 19 and Network = 'SAMobile'","date_format(calldate, '%Y-%m-%d %H:M:S')")//
as you can see In MySQL the "date_format(calldate, '%Y-%m-%d %H:59:59'),avg(billsec)" has to be quoted like this, so it can recognise it as a single parameter, since , '%Y-%m-%d %H:59:59' is viewed as another parameter
thaks for your reply

Return records from Stored Procedure to Callable Statement

Hi All,
I am createing a web application to display a students score card.
I have written a stored procedure in oracle that accepts the student roll number as input and returns a set of records as output containing the students scoring back to the JSP page where it has to be put into a table format.
how do i register the output type of "records" from the stored function in oracle in the "registerOutParameter" method of the "callable" statement in the JSP page.
if not by this way is there any method using which a "stored function/procedure" returning "record(s)" to the jsp page called using "callable" statement be retrieved to be used in the page. let me know any method other that writing a query for the database in the JSP page itself.

I have a question for you:
If the stored procedure is doing nothing more than generating a set of results why are you even using one?
You could create a view or write a simple query like you mentioned.
If you're intent on going the stored procedure route, then I have a suggestion. Part of the JDBC 2.0 spec allows you to basically return an object from a CallableStatement. Its a little involved but can be done. An article that I ran across a while back really helped me to figure out how to do this. There URL to it is as follows:
http://www.fawcette.com/archives/premier/mgznarch/javapro/2000/03mar00/bs0003/bs0003.asp
Pay close attention to the last section of the article: Persistence of Structured Types.
Here's some important snippets of code:
String UDT_NAME = "SCHEMA_NAME.PRODUCT_TYPE_OBJ";
cstmt.setLong(1, value1);
cstmt.setLong(2, value2);
cstmt.setLong(3, value3);
// By updating the type map in the connection object
// the Driver will be able to convert the array being returned
// into an array of LikeProductsInfo[] objects.
java.util.Map map = cstmt.getConnection().getTypeMap();
map.put(UDT_NAME, ProductTypeObject.class);
super.cstmt.registerOutParameter(4, java.sql.Types.STRUCT, UDT_NAME);
* This is the class that is being mapped to the oracle object.
* There are two methods in the SQLData interface.
public class ProductTypeObject implements java.sql.SQLData, java.io.Serializable
    * Implementation of method declared in the SQLData interface. This method
    * is called by the JDBC driver when mapping the UDT, SCHEMA_NAME.Product_Type_Obj,
    * to this class.
    * The object being returned contains a slew of objects defined as tables,
    * these are retrieved as java.sql.Array objects.
     public void readSQL(SQLInput stream, String typeName) throws SQLException
        String[] value1 = (String[])stream.readArray().getArray();
        String[] value2 = (String[])stream.readArray().getArray();
     public void writeSQL(SQLOutput stream) throws SQLException
}You'll also need to create Oracles Object. The specification for mine follows:
TYPE Detail_Type IS TABLE OF VARCHAR2(1024);
TYPE Product_Type_Obj AS OBJECT (
value1 Detail_Type,
value2 Detail_Type,
value3 Detail_Type,
value4 Detail_Type,
value5 Detail_Type,
value6 Detail_Type,
value7 Detail_Type,
value8 Detail_Type);Hope this helps,
Zac

How to get the returned value from Functions with Callable statement?

I was glad to find that stored procedures can be invoke with Java class code by the object of Callable statement like :
String stmt = "BEGIN departments_pkg.do_select(?,?,?); END;";
and getting the output variables by
populateAttribute(DEPARTMENTNAME,st.getString(2),true,false);
But i would like to get values returned from FUNCTION other than stored procedure, how can i achieve it? Thanks a lot!

Here is my code
PROCESS BEFORE OUTPUT.
MODULE STATUS_1202.
MODULE subscreen_find.
CALL SUBSCREEN SUBSEARCH INCLUDING sy-cprog dynnr.
PROCESS AFTER INPUT.
MODULE USER_COMMAND_1202.
CALL SUBSCREEN SUBSEARCH.
MODULE subscreen_find.
case sy-ucomm.
    when 'SELECTED'.             "fcode
      case 'ZSKILL_SEARCH'.     "data element
        when '01'.                       " value range
          dynnr = 0110.
        when '02'.
          dynnr = 0111.
      endcase.
endcase.
ENDMODULE.

Problem in callable statement

Hi All,
I have a get the data from table using CALLABLE statement.The problem is that that column datatype is CHAR.Is there any statement in java for to set
CallableStatement cstmt=null;
cstmt.setChar() ----- is it correct?

Sorry for mistyping, I meant:
Oracle CHAR type is mapped to Java String.
cstmt.setString() should do.

Please, Not getting result set from callable statement (Code posted)

I am posting some simple code which should get a ResultSet from a CallableStatement object using the executeQuery() Method.
It is returning "No RsultSet was produced"
If I modify the code and simply output the CallableableStatement using its executeUpdate() then getString() methods it works fine. Anything obviously wrong with this bit of code? Thanks.

I've posted the code...it's doing a select. I think the problem is that to return multiple rows I need to return a cursor. But I've run into problems with both the MS and Oracle Drivers.
All I really want to do is to query a database using a callable statement(function in oracle) which will return multiple rows which I can process. I have been trying to do this in a servlet.
I can do it successfully for one column from one row, but not multiple columns from mulitple rows.
I've been searchging for some good examples and am trying different things but can't seem to get it to work.

How to pass Array of Java objects to Callable statement

Hi ,
I need to know how can I pass an array of objects to PL/SQL stored procedure using callable statement.
So I am having and array list of some object say xyz which has two attributes string and double type.
Now I need to pass this to a PL/SQL Procedure as IN parameter.
Now I have gone through some documentation for the same and found that we can use ArrayDescriptor tp create array (java.sql.ARRAY).
And we will use a record type from SQL to map this to our array of java objects.
So my question is how this mapping of java object's two attribute will be done to the TYPE in SQL? can we also pass this array as a package Table?
Please help
Thanks

I seem to remember that that is in one of Oracle's online sample programs.

How it works (Calling Stored Procedure in DB2 Through Callable statement)

Can anyone Please tell me what exactly happens on calling ESP(External Stored Procedure) through Callable statement Database point of view and Callable point of view also.
eg:
CallableStatement cstmt = con.prepareCall(
"{call getTestData(?, ?)}");
cstmt .executeUpdate();
where getTestData is Stored Procedure in DB2.
Can anyone please guide me working on this scenario..

Error executing a callable statement on a pooled connection

Hi,
I have an Oracle function that returns a number:
create or replace function
S2B_STOP_STAGE (DOC_ID number, ST_ID number)
return number ...
and the following Java code:
Class.forName("weblogic.jdbc.pool.Driver").newInstance();
conn = DriverManager.getConnection("jdbc:weblogic:pool:madrigalPool");
String sql = "{? = call S2B_STOP_STAGE(401,1002)}";
CallableStatement stmt = conn.prepareCall(sql);
stmt.registerOutParameter(1, Types.INTEGER);
stmt.execute(sql);
res = stmt.getInt(1);
When the execute(sql) statement is executed, a SQLException is thrown:
java.sql.SQLException: ORA-01008: not all variables bound
at weblogic.jdbc.pool.PreparedStatement.execute(PreparedStatement.java:121)
Does anybody have an idea about what may be wrong? I am using Oracle
8.1.6, the thin driver classes12-81620.zip, and WebLogic 6.0 sp2.
Thanks,

I found out what was wrong. I should have used execute() instead of execute(sql)
on the callable statement...
Sorry for the problem.

Statement closed when using callable statements with oracle xe

hi all, i've got this problem with oracle express edition 10g. I am using also oc4j v10.1.2.0.2. When working with a normal oracle database it was working fine (i think the code was the same, it's some time since i last tried, but you can see the code is very simple).
So i just create a callable statement like this:
CallableStatement cs = con.prepareCall(sentencia.toString(), ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE, ResultSet.HOLD_CURSORS_OVER_COMMIT);
and then when trying to access the statement to register an out parameter like this
cs.registerOutParameter(1, parámetros[0].getTipo());
it gives this error:
java.sql.SQLException: Statement was closed
It's puzzling me because, as i said before, i think the same code was working ok with a normal oracle database.
Any idea what can it be?
cheers

Ah okay, sorry I've re-read your post.
I believe you need to create a clob object that encapsulates your xml file.
I've never done this but I would image it involves creating a class that implements the clob interface and passing an instantiation of this class to the callablestatement.
Let me know how you get on.

Callable statement problem-very urgent

Hi Friends,
i have 2 tables, in that two tables one column have same attribute column. when i update the first table through OAF page, i wanted to effect updated value in second table of that common field also. i wrote PL/SQL Procedure and called that into OAF by using callable statements. here first time i updated in the page, updated value is effecting into the first table while second table not effected the updated value. again i am trying to update the page this time in second table effected with first time updation value,while first table updated correctly. suppose i updated again in the page this time in second table effected with second time updation value, while first table updated correctly.this process continuing...
example – I want to update forecast(this field is in two tables) value filed. Now forecast value is 10 in both tables , I updated as 20. this 20 updated value effected first table while second table forecast field is not effected.
Again I am going to update value 30 in the place of 20. this 30 updated value effected first table while second table forecast field is 20(firstupdated value) effected.
Again I am going to update value 40 in the place of 30. this 40 updated value effected first table while second table forecast field is 30(secondupdated value) effected this process continuing...
Can any one help me out this problem
This is I have written in AM-
public void Callable()
String forecast="";
String name="";
String product="";
String business="";
XXProgsVOImpl vo = getXXProgsVO1();
RowSetIterator rowsetiterator=vo.getRowSetIterator();
rowsetiterator.reset();

Hi Sumit and Thiago,
Thanks for your information, my Both VO's are coming from EO'S. but first VO I have done some calculation on columns, that calulated value parameter passing to second page. this calculated value is the database column in second table. here when i update the calculated value in updated page , i want to effect this in second page table.
do you have any work around this..
Thanks and Regards,

Callable Statement Syntax

I am using the callable statement to invoke a MS SQL Server stored procedure that will return a result set. I have several questions:
1) According to the Java documentation I should be using the following format for a prepareCall that will return a result paramater with 4 input paramaters:
{ ? = call SP_ABC(?, ?, ?, ?)}
In my particular case the stored procedure will return 14 pieces of data in a result set. Do I need to write code for 14 registerOutParameter fields? Is the syntax mentioned above accurate for the 14 pieces of data or do I need to repeat the question marks (?) 14 times? What shoud the syntax be for my prepareCall statement?

The ? in the sql syntax refer to variables passed to the procedure as either in or in/out parameters. You need to write code to register any OUT variables (including any return value).
The data returned from the SP will be returned as a ResultSet which is processed in the normal way.
So assuming that you have a procedure declared as:
create proc p @1 int, @2 int OUTPUT as ...then your code would look like this:
statement = connection.prepareCall("{?=call p (?,?}");
// register the return code
statement.registerOutParameter(1,Types.INTEGER);
// register the OUTPUT var @2
statement.registerOutParameter(3,Types.INTEGER);
// Set the input param @1
statement.setInt(2,0);
rs = statement.executeQuery();
// Get the return code
int rc = statement.getInt(1);
// Get the output param @2
int out = statement.getInt(3);
// process the result set
while(rs.next()) {...}Dave
