Return Rows from Stored Procedure - My 1st Attempt
Hi Everyone,
The code below compiles with error 'Error(11,1): PLS-00103: Encountered the symbol "/" '.
I'm using SYSDATE in this example for simplicity. The real procedure will do much more.
Thank You in Advance for Your Help,
Lou

Ora-06550 returning data from Stored Procedure and Entity Data Model
Hi.
I'm creating an application that uses a WCF Service to return data. I also created a proyect with the EDMX design and mapped most of my DBModel to a classes context. I have added some of the procedures as well. One of them receive some parameters and return a Sys_RefCursor, that is populated according to the parameters.
I have declared the "<add >" tags in the Web.Config and imported the function of the Procedure. When I call the Asyncronous function I get different exceptions:
1. If I call the function, with all of the parameters i get:
Oracle.DataAccess.Client.OracleException: ORA-06550: línea 1, columna 8:
PLS-00306: número o tipos de argumentos erróneos al llamar a
'SP_HECHOSJURITER'
ORA-06550: línea 1, columna 8:
(wrong number or types of arguments in call to 'SP_HECHOSJURITER')
2. If i just set 1 parameter in the SP, returning the same type of data, I get:
Error al recibir la respuesta HTTP a
http://localhost/Procalculo.CGFM.SIGOC.DatosServices/ServiceDatos.svc.
(failed to receive http response. error 12152)
3. If I don't set any parameters in the procedure, it works fine, and return correct data.
It exclusively happen with one entity.
Any clue?
I appreciate any help.When you return result sets from stored procedures to Entity Framework, you are very likely using implicit result sets. Implicit result sets don't need to be declared as a parameter in code, only in the <add> tags to define the metadata in the .NET config file.
For example, in the EF Oracle By Example, you'll see that the stored procedure in the function import has three parameters, but only two are declared in the code. The third one was defined in the config file.

OCI8: returning cursors from stored procedures
The short version of my question is:
In OCI8, how do open a cursor from the database stored procedure, return it to my C++ program and fetch from it, given that in OCI8 cursors and cursor functions are becoming obsoleted?
The long version of the same question is:
I am converting my C++ code from the Oracle 7.3 OCI driver to the Oracle8 OCI driver. One thing I did very frequently in Oracle 7.3 OCI code is open a multi-row select cursor within a stored procedure and return that cursor to my program. In the program, I would then do the fetching with the returned cursor. This was very useful, as it allows me to change the queries in the stored procedure (for example, to append information to certain columns or make some data in all uppercase) without recompiling the application due to a changed SQL string.
My 7.3 psuedocode is as follows:
stored procedure def:
TYPE refCurTyp IS REF CURSOR;
FUNCTION LoadEmployeeData RETURN refCurTyp;
stored procedure body:
FUNCTION LoadEmployeeData RETURN refCurTyp IS
aCur refCurTyp;
BEGIN
OPEN aCur FOR
SELECT emp_id, emp_name
FROM employee_table
ORDER BY emp_name;
return aCur;
END;
OCI code: // all functions are simplified, not actual parameter listing
// declare main cursor variable #1 and return cursor variable #2
Cda_Def m_CDAstmt, m_CDAfunction;
// open both cursors
oopen(m_CDAstmt, ...);
oopen(m_CDAfunction, ...);
// bind cursor variable to cursor #2
oparse(&m_CDAstmt, "BEGIN :CUR := MYPACKAGE.LoadEmployeeData; END;");
obindps(&m_CDAstmt, SQLT_CUR, ":CUR", &m_CDAfunction);
// run cursor #1
oexn(&m_CDAstmt);
// bind variables from cursor #2, and fetch
odefineps(&m_CDAfunction, 1, SQLT_INT, &m_iEmpId);
odefineps(&m_CDAfunction, 2, SQLT_CHAR, &m_pEmpName);
while (!ofen(&m_CDAfunction))
// loop: do something with fetch
// values placed in m_iEmpID and m_pEmpName
This works perfectly, and has really helped to make my code more maintainable. Problem is, in Oracle 8 OCI both cursors and the cursor functions (such as oopen()) are becoming obsoleted. Now it uses statement and environment handles. I know I can still use Cda_Def and cursors--for a while--within OCI8, but I need to know the official up-to-date method of returning a cursor from the database and fetching within my C++ code. Any code fragment, or explanation of what I need to do in OCI8 would be appreciated (perhaps I need to bind to a statement handle instead? But the stored procedure still returns a cursor.)
The Oracle8 OCI has a new SQLT_ type, SQLT_RSET, which the header file defines as "result set type". Unfortunately, it's almost completely undocumented in the official documentation. Am I supposed to use this instead of the obsolete SQLT_CUR?
Thanks,

Returning object from stored procedures
I am having a lot of trouble finding an example to demonstate how I return a Java/DB Object from a Java Stored Procedure. All the examples I have been able to find return one of the native types (VARCHAR, NUMBER, etc). As an example...
public static DataPoint getPoint() {
return new DataPoint(
new Timestamp(System.currentTimeMillis()),
new BigDecimal(50.0));
Assuming DataPoint is a Java class mapped to an Oracle Data Type created via the following statement.
create or replace type data_point as object (
p_date date,
p_data number
After loading and publishing the procedure I get no (zero, 0) rows returned when calling. I should be getting one row returned.
Thanks,
MikeMike,
You said:
Assuming DataPoint is a Java class mapped to an Oracle
Data TypeI think your assumption is incorrect.
In any case, isn't this what "TopLink" is used for?
(I don't know, since I don't use "TopLink".)
Have you tried the TopLink/JPA forum?
Good Luck,
Avi. -
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,

and i am trying to get the return value from execute sql task and shown below
and i am taking my returnn value to result set variableYou need to have either OUTPUT parameters or use RETURN statement to return a value in stored procedures. RETURN can only return integer values whereas OUTPUT parameters can be of any type
First modify your procedure to define return value or OUTPUT parameter based on requirement
for details see
http://www.sqlteam.com/article/stored-procedures-returning-data
Once that is done in SSIS call sp from Execute SQL Task and in parameter mapping tabe shown above add required parameters and map them to variables created in SSIS and select Direction as Output or Return Value based on what option you used in your
procedure.

Returning recordset from stored procedures
Hi
I am trying to get a stored procedure to return multiple values (i.e. a recordset) and want to access them from JDBC. Is that possible?
Frankie =:>You can return nested tables and varrays using JDBC. See chapter 10 of the Oracle JDBC Developer's Guide.

Returning rows from stored proc
Hello, this is the sample from the SQL Developer help to create proc:
CREATE OR REPLACE
PROCEDURE list_a_rating(in_rating IN NUMBER) AS
matching_title VARCHAR2(50);
TYPE my_cursor IS REF CURSOR;
the_cursor my_cursor;
BEGIN
OPEN the_cursor
FOR 'SELECT title
FROM books
WHERE rating = :in_rating'
USING in_rating;
DBMS_OUTPUT.PUT_LINE('All books with a rating of ' || in_rating || ':');
LOOP
FETCH the_cursor INTO matching_title;
EXIT WHEN the_cursor%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(matching_title);
END LOOP;
CLOSE the_cursor;
END list_a_rating;
You have to write a cursor just to display results from a query. To me this is whacked but I'll go with it. So what if you wanted to return that resultset or refcursor so it can be consumed by a calling application or procedure? I tried something like
CREATE OR REPLACE PROCEDURE list_a_rating(in_rating IN NUMBER, MatchingTitles OUT Ref Cursor)
but that's not compiling. How do you return data from a proc or function?
Thanks,
Kenktrock wrote:
Hello, this is the sample from the SQL Developer help to create proc:A very poor example..
You have to write a cursor just to display results from a query. To me this is whacked but I'll go with it. All SQL you send to Oracle for parsing and execution winds up as SQL cursors in the server's SQL shared pool. You, the client, then get a handle as reference to this cursor that was created for your SQL statement. Using this handle you can now fetch the output of the cursor and consume it on the client side.
So there is no such thing as not using a cursor - you always use cursors. Many times it will be implicitly as you won't see the cursor workings as the client hides that from you.
As for DBMS_OUTPUT and PL/SQL... PL/SQL cannot "write output". And time and again (stupid?) people will use DBMS_OUTPUT thinking that is "writing to the client's display device".
It is not. It is writing data into a PL/SQL variable on the server. PL/SQL variable that consumes very expensive dedicated process memory on the server. The client (SQL-Developer, TOAD, SQL*Plus, etc) can read the contents of this variable and the client can render that contents on the client's display device.
So how on earth does it make sense to take SQL data on the server (that is structured data and can vary significantly in volume), and write that as plain text into a PL/SQL variable?
It does not make sense. At all. Bluntly put - it is just plain bloody stupid.
So how do you return data using PL/SQL? The same way as you return data using SQL.
PL/SQL allows the complexity of the SQL language, database model and so on to be moved from the client application into PL/SQL itself. The client thus no longer need to know table names, what to join where and when, how to write effective SQL and so on. It calls a PL/SQL procedure with optional parameters. This procedure has the logic to create the required SQL (based on the parameters too if applicable) and return the cursor handle for that SQL.
The client thus calls PL/SQL, PL/SQL serves as the SQL abstraction layer and does the complex SQL bit, and PL/SQL then returns the SQL cursor handle to the client.
In the PL/SQL language, there are different data types for dealing with the same SQL cursor handle - depending on what you want to do with that SQL cursor.
If you want to pass that SQL cursor handle to a client, then you need to use the sys_refcursor data type in PL/SQL. Remember that SQL cursor does not know or care what data type the client (such as PL/SQL) uses to reference it. All SQL cursors in the server's shared pool are the same - how you treat them from a client side (as an explicit cursor, implicit cursor, ref cursor, etc) is a client program decision.
Also keep in mind that a SQL cursor is NOT a result set. It is not a data set that is instantiated or created on the server that contains the data (or references to the data) for your SQL.
If this was the case - just how many such cursor result sets could the server create before running out of memory?
A cursor is an executable program. The source SQL code is compiled into a program called a cursor. This cursor contains the execution steps that the server needs to follow to find the data. The cursor then outputs this data as data is found. The execution plan of a cursor shows how this program looks like. -
How to capture return value from stored procedure?
Hi All,
I want to capture the retun values from this procedure to a table - CALL SYS.GET_OBJECT_DEFINITION('SCHEMA_NAME', 'TABLE_NAME').
The below approach is not working -
Insert into STG.STG_DDL
Call SYS.GET_OBJECT_DEFINITION('DWG', 'DWG_SITE')
Could you please have a look on the same?

Returning SQL cursor from Stored Procedure
Hi,
I have a query regarding returning sql cursor from stored procedure to java in oracle 11g.
I want to query some data ex: my query returns A, B, C. Also, now I want to query some other data ex: D, E, F. Now I want to return this data as an sql cursor as a single row . Example: A,B,C,D,E,F. Is it possible to return/create a cursor in stored procedure?
assume both query returns equal number of rows.. however both are not related to each other..RP wrote:

assume both query returns equal number of rows.. however both are not related to each other..It sounds like what you need is a ref cursor.
First thing to remember though is that cursors do not hold any data (see: {thread:id=886365})
In it's simplest form you would be creating a procedure along these lines...

3 open p_rc for p_sql;

Returning rowcount and resultset from stored procedure
Hello,
In SQL Server you can return multiple resultsets from stored procedure by simple SELECT statement. But in Oracle, you have to use SYS_REFCURSOR.
Sample code:
CREATE OR REPLACE PROCEDURE sp_resultset_test IS
t_recordset OUT SYS_REFCURSOR
BEGIN
OPEN t_recordset FOR
SELECT * FROM EMPLOYEE;
END sp_resultset_test;
Is there any other way in Oracle 10 or 11 ?
Thank You.What is the requirement? Oracle is far more flexible than SQL-Server... with numerous features that do not exist in SQL-Server. (Fact)
One of the biggest mistakes you can make is to treat Oracle like SQL-Server... trying to match feature A1 in SQL-Server to feature B3 in Oracle.
Does not work that way.. rather then stick to SQL-Server as SQL-Server does SQL-Server specific features far better than Oracle.
So instead of trying to map what a T-SQL stored proc to do to an Oracle ref cursor (even to the extent of using that very silly sp_ prefix to name the proc), tell us the problem and requirements... That way we can tell you what Oracle features and options are best used to solve that problem - instead of competing in some unknown feature comparison event with SQL-Server. -
URGENT : Return Bulk data from Stored Procedure
Hi,
Tell me, how do I return a bulk of data which
does not exist in the data base
but is concluded while the Stored Procedure is executed
from the Stored procedure
to the C++ program.
For Example:
Table ABC
Field1 Field2 Field3
A 1 3
B 1 5
C 2 10
Table DEF
Field1 Field2 Field3
D 10 24
E 3 16
F 8 19
SP_TESTING
Depending on the values in both the tables
for some range of conditions,
a conclusion X is derived for each range value of the
condition range.
Now I need to return this bulk of data X with the
condition they belong to
back to the C++ code calling it....
NOTE : A stored procedure is requited as there is a lot
of processing
required before we conclude the result X for each value
in the condition range.
If I execute this code from C++ instead of Stored
procedure
it is very slow and speed is a prime requirement of my
system.
Also i'm not using any MFC class to access database.
I'm using ConnectionPtr, RecordsetPtr and _CommandPtr
from msado15.dll for database access...
One solution to this could be use of Temp tables.
As this process is used by a lot of different stored
procedures having a common
temp table to all will need something like 50 NUMERIC
fields, 50 VARCHAR fields
and so on, which doesn't seem like a very good solution
to this problem.
Sounds like something I would have done while in school,
implement a dumb solution.
So, please suggest me a solution as to how do I return
bulk data in the form
of recordsets from stored procedure.

Thank you for your help!!!
I've created a stored procedure to return results as xml. I'm having trouble figuring out why I'm getting the error message "Conversion failed when converting the nvarchar value '<tr>.....'
to data type int. It seems like the system doesn't know that I'm returning a string... Or, I'm doing something that I just don't see.
ALTER PROCEDURE [dbo].[p_getTestResults]
@xml NVARCHAR(MAX) OUTPUT
AS
BEGIN
CREATE TABLE #Temp
[TestNameId] int,
[MaxTestDate] [DateTime],
[Name] [nvarchar](50),
[Duration] [varchar](10)
DECLARE @body NVARCHAR(MAX)
;WITH T1 AS
SELECT DISTINCT
Test.TestNameId
, replace(str(Test.TotalTime/3600,len(ltrim(Test.TotalTime/3600))+abs(sign(Test.TotalTime/359999)-1)) + ':' + str((Test.TotalTime/60)%60,2)+':' + str(Test.TotalTime%60,2),' ','0') as Duration
,MaxTestDate = MAX(TestDate) OVER (PARTITION BY TM.TestNameId)
,TestDate
,TM.Name
,Test.TotalTime
,RowId = ROW_NUMBER() OVER
PARTITION BY
TM.TestNameId
ORDER BY

inner join TestName TM on Test.TestNameID = TM.TestNameID
where not Test.TestNameID in (24,25,26,27)
INSERT INTO #Temp

,T1.[Name]
,T1.Duration
FROM

WHERE

ORDER BY

SET @body ='<html><body><H3>TEST RESULTS INFO</H3>
<table border = 1>
<tr>
<th> TestNameId </th> <th> MaxTestDate </th> <th> Name </th> <th> Duration </th></tr>'
SET @xml = CAST((
SELECT CAST(TestNameId AS NVARCHAR(4)) as 'td'
, CAST([MaxTestDate] AS NVARCHAR(11)) AS 'td'
, [Name] AS 'td'
, CAST([Duration] AS NVARCHAR(10)) AS 'td'
FROM #Temp
ORDER BY TestNameId
FOR XML PATH('tr'), ELEMENTS ) AS NVARCHAR(MAX))
SET @body = @body + @xml +'</table></body></html>'
DROP TABLE #Temp
RETURN @xml
END
closlYour dont need RETURN inside SP as you've declared @xml already as an OUTPUT parameter. Also you can RETURN only integer values using RETURN statement inside stored procedure as that's default return type of SP.
so just remove RETURN statement and it would work fine
To retrieve value outside you need to invoke it as below
DECLARE @ret nvarchar(max)
EXEC dbo.[P_gettestresults] @ret OUT
SELECT @ret

Updatable ADO recordset returned by a stored procedure
I am trying to have an updatable ADO recordset returned by a stored procedure.
However, LockType for this recordset is always adLockReadOnly.
What needs to be done to have LockType changed?
I am using the following simplified example from Oracle doc. According to Oracle® Provider for OLE DB Developer's Guide 10g Release 2,
the following ADO code sample sets the Updatability property on a command object to allow insert, delete, and update operations on the rowset object.
Dim Cmd As New ADODB.Command
Dim Rst As New ADODB.Recordset
Dim Con As New ADODB.Connection
Cmd.ActiveConnection = Con
Cmd.CommandText = "SELECT * FROM emp"
Cmd.CommandType = adCmdText
cmd.Properties("IRowsetChange") = TRUE
Cmd.Properties("Updatability") = 7
' creates an updatable rowset
Set Rst = cmd.ExecuteHowever, the result is not updatable. Can you please advise.Returning a REF CURSOR is certainly the easiest of the options, particularly if you're trying to use ADO. Without doing something really klunky, all your options are going to result in read-only result sets.
Assuming you have a procedure-based interface to your data, the easiest option is generally to do your own updates by explicitly calling the appropriate stored procedures.
As a bit of an aside, in order to offer updatable result sets, the ODBC/ OLE DB/ etc provider generally has to do something along the lines of
1) Take the SQL statement you pass in
2) Modify it to select the ROWID in addition to the other columns you're selecting
3) Store the ROWID internally and use that as a key to figure out which row to update
Once you eliminate the ability of the client to manipulate the query, you've pretty well eliminated the ability of the driver to implement generic APIs for updates. The client at that point has no idea which row(s) in which table(s) a particular value is coming from, so it has no idea how to do an update. You generally have to provide that knowledge by coding explicit updates.

How to generate a report from stored procedure
I would like to generate a report from stored procedure.
I used to work on sql server. this can be done as easy as put a select statement at the end of stored procedure.
The resule can be displayed on the development IDE, like sql developer or consume by Java JDBC client.
is there equivalent way to do this in Oracle stored procedure?Hi,
What type of report you are looking..for.. ??
As you said that "I used to work on sql server. this can be done as easy as put a select statement at the end of stored procedure. "
When you execute it will return the result set and you will display directly on the FrontEnd.. Is my Understanding is correct Up to here.
See, In oracle you have call some custom stored procedures as you did in SQL Sever, but you have return the Results Sets, with help of Out put paramter, Either Cursors or Varrays..
or Else you can generate the Html reports based on your requirement, HTML can be used in the stored procedures of Oracle which will generate for your, you need to code it.
I could not able get the relevant link for your reference.
I will get back to you on this.
