StoredProcedure Vs PreparedStmt or statement

Hi
Is stored procedures always better than doing a prepared statement or a normal statement
Does any one have a link to some benchmark on the performance issues on this
Thanks in advance
DN

They're all useful for different situations.
Stored Procedures are database specific and would be useful if you have no plans on changing database engines and have queries of complex procedures you will be using regularly. As it lives on the database engine, it's sure to have any queries within it pre-compiled and optimized. It is also useful for doing much more than simple queries.
Prepared Statement is useful if you have a SQL query or update that is going to be used several times (perhaps in a loop) with a few select fields being changed each loop. This allows the database engine to pre-compile and optimize the known portion of the SQL query or update.
A simple Statement is useful if you're only doing a simple SQL query or update (perhaps dynamically built) that's not going to be re-used in some sort of loop condition.
So, a benchmark isn't really too meaningful. It really matters more what you are trying to accomplish.

Memory Leak in 8.1.6.0.1 JDBC/OCI for Solaris

Hello,
there is a memory leak in the 8.1.6.0.1 JDBC-OCI driver for solaris.
The leak causes your jvm to eat up all memory
if you reuse callable statements
(calling one statement multiple times with
different values).
The thin driver has no such problem. Is
there any fix available ?

Ok. The code spans multiple classes and
most of it comes from a customized version
of the Enhydra Java Application server.
I have a class called "StandardDBConnection"
which caches CallableStatements and is a
wrapperclass for java.sql.DBConnection. The
interesting method here is "prepareCall":
* Get a callable statement given an SQL string. If the statement is
* cached, return that statement, otherwise prepare and save in the
* cache.
* @param sql The SQL statement to be called.
* @return a new CallableStatement object containing the
* pre-compiled SQL statement.
* @exception java.sql.SQLException If a database access error occurs
* statement.
public synchronized CallableStatement prepareCall(String sql)
throws SQLException {
PreparedStatement preparedStmt;
logDebug ("Prepare call: " + sql);
validate();
preparedStmt = (PreparedStatement)preparedStmtCache.get(sql);
// Check if the object returned by the cache really is a
// callable statement. if it is not, someone did call first
// prepareStatement() and now prepareCall() with the same
// sql. Silently replace the existing cache entry by a
// callable statement in this case.
if (preparedStmt instanceof CallableStatement) {
preparedStmt.clearParameters();
else {
// Need to close the old PreparedStatement in case we have to
// replace it with a CallableStatement
if (preparedStmt != null) {
preparedStmt.close();
else if (preparedStmtCache.size() >= maxPreparedStmts) {
String key = (String)preparedStmtCache.keys().nextElement();
((PreparedStatement) preparedStmtCache.remove(key)).close();
preparedStmt = connection.prepareCall(sql);
preparedStmtCache.put(sql, preparedStmt);
return (CallableStatement)preparedStmt;
The statements get closed when I close the
connection:
boolean closeStmts = true;
// Close the prepared statements.
Enumeration e = preparedStmtCache.keys();
while (e.hasMoreElements() && closeStmts) {
String key = (String)e.nextElement();
try {
((PreparedStatement)
preparedStmtCache.remove(key)).close();
} catch (SQLException except) {
// Ignore errors, we maybe handling one.
closeStmts = false;
log.write(Logger.NOTICE,
"DBConnection[" + id + "]: " + url +
"\nUnable to close statements. Continuing....\n");
In my classes using database queries I just
use the prepareCall method of DBConnection
and do not have to care about anything.
Works perfectly with the thin driver, but
as soon as I switch to oci... :-|

Problems with StoredProcedures that use INSERT/DELETE statements

Hello
I am using Hyperion Intelligence explorer 8.5, and the database source is a MS SQL Server 2000 source connected via ODBC.
I have this problem: when I use, in a Query section, a stored procedure that (in its code) uses only SELECT statements I get the result of the query in the Results section, but when I use a storedprocedure that does some work (and executes INSERT or DELETE or other SQL statements) and ends executing a SELECT statement in order to return data to the caller Hyperion hangs.
I mean: first I select the stored procedure (Query\StoredProcedure... menù, than I start it using the Process command in Hyperion.
If the storedproc contains only SELECT statements I get the results, but if it contains INSERT or DELETE (and the last statement is a SELECT) Hyperion does not return any data and if I try to repeat the Process command I get an error that tells "the connection is busy with results from another hstmt".
Before you ask me if the stored procedure works correctly, I can confirm this because the storedproc was tested and returns the correct data if used with the db manager application.
Any suggestions? Did you ever use (successfully )storedprocedures that process data (by INSERT or DELETE statements) and then return the result with a SELECT statement?
Thank you for your help

Hi Chris,
Could you please tell us in which version of IR
Hyperion is not going to support Stored
Procedures....
Regards,
ManmohanManmohan,
Did you even read what I just wrote? This is NOT happening. Stroed Procedures are an important part of the Intelligence Product, Oracle is continuing to enhance and support this functionality. I work for Oracle, I worked for Hyperion, and for Brio before that, so believe me when I tell you this.
Chris (whoever he is) is gving out incorrect information in this regard. His suggestion of the workaround for the original issue is completely accurate, but as I added, it was in issue that has been corrected as of 8.5 Service Pack 2, so even the workaround is not required as long as you've upgraded. (Note that some versions of 9.x also will require the workaround due to the timing of the releases overlapping.)
Thanks.

Report with stored proc running multiple stored procedures with insert statement

Hi,
I wonder if this is possible in SSRS ... I use the 2012 version (Data Tools).
I have a report that triggers a stored procedure. See below.
Within this SP there are 2 insert statements getting data from 2 other SP's.
When I make a dataset referring to the main SP below, SSRS does not show me any fields at all.
Is this because it's a SP with insert statements and nested SP's?
At the end of the SP I make a select so it should see all the fields.
The parameters @month and @costcenter are multivalue params. I use a special function to convert the multivalues, selected in the report, into a string to pass it correctly to the query (comma separated).
USE [TestDB]
GO
/****** Object: StoredProcedure [dbo].[_Pink_SP_StandingsRegisterDataset] Script Date: 15-4-2014 13:31:30 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[_Pink_SP_StandingsRegisterDataset]
@year INT,
@month NVARCHAR(50),
@costcenter NVARCHAR(500),
@GLaccount NVARCHAR(9)
AS
BEGIN
/* Remove existing content*/
DELETE FROM _Pink_TB_StandingsRegister
/* Add records part 1 */
INSERT INTO _Pink_TB_StandingsRegister
EXEC _Pink_SP_StandingsRegister @year, @month, @costcenter, @GLaccount
/* Add records part 2 */
INSERT INTO _Pink_TB_StandingsRegister
Type,
Row,
Year,
Month,
YearDatetable,
MonthDatetable
EXEC _Pink_SP_StandingsRegisterDatetable @year
/* Select all records */
SELECT *
FROM _Pink_TB_StandingsRegister
END
GO

Hi bijntjede2e,
After testing a similar scenario in my own environment, it works well in Reporting Services. In my test, the stored procedure returns all the fields from _Pink_TB_StandingsRegister table in the dataset. Then I select some values from year, month, costcenter
and Glaccount parameters, it inserts some values in the _Pink_TB_StandingsRegister table. So we can use this stored procedure as the dataset in the report.
In order to solve the problem more efficiently, I need to clarify some information.
Are you pass multiple values parameter to one stored procedure correctly? We can refer to the following thread:
http://social.technet.microsoft.com/Forums/en-US/dbdfa101-cccc-4e9f-aa50-566dc5ebcc27/ssrs-2008-r2-report-dataset-call-a-stored-procedure?forum=sqlrep
What results are you get when executing the stored procedure in SQL Server Management Studio? Is it works well? We should double those stored procedures.
If there are any misunderstanding, please elaborate the issue for further investigation.
Thanks,
Katherine Xiong

ForEach Loop Container Mapping Variable From SSIS Package Not Working In SQL-Server StoredProcedure

I have an SSIS package that uses a ForEach Loop Container to enumerate Excel Files in a dir. I also have a Task Flow that inserts data from those Excel files into SQL-Server.
Im trying to insert the file names into a column into the same table in SQL-Server by using a mapping variable in my StoredProcedure.
Im having trouble with my MappingVariable at the end of the script with red squigglies. The following is my StoredProcedure script.
CREATE PROCEDURE [dbo].[Insert_F_STG_v2]
-- Add the parameters for the stored procedure here
@Hrs float,
@Type nvarchar(100),
@SN nvarchar(100),
@Op nvarchar(100),
@[USER::CurrentFileName]
AS
BEGIN
SET NOCOUNT ON;
INSERT INTO [CRM_RC].[dbo].[F_StgTbl]
[Hrs],
[Type],
[SN],
[Op],
[Report_Date]
VALUES
@Hrs ,
@Type,
@SN,
@Op,
@[USER::CurrentFileName]
END
The last @[USER::CurrentFileName] in the Values block at the bottom of the script is the one giving me issues.
The following is the error:
Msg 102, Level 15, State 1, Procedure Insert_F_STG_v2, Line 95
Incorrect syntax near 'USER::CurrentFileName'.

This seems to be the solution, but get the following exception:
[Derived Column [2]] Error: The "Derived Column" failed because truncation occurred, and the truncation row disposition on "Derived Column.Outputs[Derived Column Output].Columns[Derived Column 1]" specifies failure on truncation. A truncation error occurred
on the specified object of the specified component.
AND: [SSIS.Pipeline] Error: SSIS Error Code DTS_E_PROCESSINPUTFAILED. The ProcessInput method on component "Derived Column" (2) failed with error code 0xC020902A while processing input "Derived Column Input" (3). The identified component returned
an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running. There may be error messages posted before this with more information about the failure.

Creating a DataTable from the results of SQL statement

I am relatively new to VB 2005, ADO and Oracle db. I have perfected an SQL statement that joins 6 tables in an Oracle 10i database and the resulting set retunrs the correct data. I am having difficulty creating and inserting this resulting set into a datatable that could be used in my application. Could someone detail the steps needed to create and fill this table

http://download.oracle.com/docs/cd/A91202_01/901_doc/appdev.901/a89856/06_ora.htm#1604
The link above points to Oracle's documentation on using cursor variables. In a nutshell, you want to create a package that defines the cursor type and contains the procedure to open the cursor.
create package my_package as
type my_cursor_type is ref cursor;
procedure my_procedure (out_cursor out my_cursor_type);
end;
create package body my_package as
procedure my_procedure (out_cursor out my_cursor_type) is
begin
open my_cursor for
select ...;
end;
end;Now you need to set up your .NET application to read the data.
OracleConnection con = new OracleConnection("User Id=myuser;Password=mypassword;Data Source=mydatabase");
OracleParameter[] parms = new OracleParameter[1];
parms[0] = new OracleParameter("table1_cursor", OracleDbType.RefCursor, ParameterDirection.Output);
OracleCommand cmd = new OracleCommand("my_package.my_procedure", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddRange(parms);
DataTable myTable = new DataTable();
OracleDataAdapter da = new OracleDataAdapter(cmd);
da.Fill(myTable);

Toplink storedProcedure/funtion + PL/SQL Procedure with cursor

Hi,
I am working on Toplink storedProcedure but, I am not getting any output. I go through the Oracle Tutorial but, still I am not getting any alternative.
please, anyone help out....
Thanking You,
regards,
sufian

Hello Sufian,
You seem to have a few threads trying to get a Stored proc working. In How to work with Toplink + PL/SQL Procedure + Cursor
you mention you get an error when executing, have you gotten past this exception? You may want to turn on TopLink logging to see the statement TopLink is creating and sending to the driver. Please see
http://www.oracle.com/technology/products/ias/toplink/doc/1013/main/_html/sescfg004.htm
If you are not familar with how to turn on logging.
Also, are you able to get results from a stored procedure that returns data instead of a cursor?
Best Regards,
Chris

Update statement inserts a new row instead of updating

My code should just update a single specific row in the table. I used a simple procedure to update a record in the current application as well and it runs without any problem except this case. Every time the query runs, it actually inserts a new row instead
of just updating an existing:
So here is my c# code:
try
command.Parameters.Clear();
command.Parameters.AddRange(vars);
command.CommandText = "Update" + tableName;
conn.Open();
command.ExecuteNonQuery();
conn.Close();
this.GetData(tableName);
catch
throw;
And here is my SQL code (please ingore 'Alter Procedure' statement, I just wanted to get the core script of the procedure):
ALTER procedure [dbo].[UpdateExpenditureItems]
(@ID int,
@Name nvarchar(50),
@IsGroup bit,
@Parent nvarchar(50),
@Description nvarchar(50)
AS
Begin
--a new inserted row seems to be a result of running IF statement rather than ELSE
if @Parent is not null
begin
declare @ParentID int
set @ParentID = (select ID from ExpenditureItems where Name=@Parent);
UPDATE ExpenditureItems SET Name =@Name, Parent =@ParentID, [Description] =@Description, IsGroup = @IsGroup WHERE ID=@ID;
end
else
begin
UPDATE ExpenditureItems SET Name =@Name, [Description] =@Description WHERE ID=@ID
end
end
I ran the query itself from sql management studio and it works fine. The problem seems to be in c# code, but there's nothing unusual. Same code for operations with the databse works fine in other parts of the software... I appreciate your help!
Thanks in advance!

Please can you post your full C# code for this function? Also the code you sent is not calling an SP? so why do we need to validate against the SP?
Fouad Roumieh
So here is my code:
//Update is called on OK button click
private void okBut_Click(object sender, EventArgs e)
//edit code runs here
SqlParameter[] pars = new SqlParameter[5];
pars[0] = new SqlParameter("@ID", int.Parse(idTB.Text));
pars[0].SqlDbType = SqlDbType.Int;
pars[1] = new SqlParameter("@Name", itemTB.Text);
pars[1].SqlDbType = SqlDbType.NVarChar;
pars[2] = new SqlParameter("@IsGroup", true);
pars[2].SqlDbType = SqlDbType.Bit;
pars[3] = new SqlParameter("@Parent", DBNull.Value);
pars[3].SqlDbType = SqlDbType.Int;
pars[4] = new SqlParameter("@Description", descTB.Text);
pars[4].SqlDbType = SqlDbType.NVarChar;
try
DAL dal = new DAL();
dal.UpdateData("ExpenditureItems", pars); //Update is called here
catch (Exception ex)
StaticValues.WriteEventLogXML(ex, this.Text);
switch (StaticValues.user.Language)
case "English":
MessageBox.Show("Database error", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
break;
default:
break;
finally
this.DialogResult = System.Windows.Forms.DialogResult.OK;
StaticValues.currentNode = itemTB.Text;
public void UpdateData(string tableNameString, SqlParameter[] vars)
string tableName = tableNameString.Replace(" ", string.Empty);
try
command.Parameters.Clear();
command.Parameters.AddRange(vars);
command.CommandText = "Update" + tableName;
conn.Open();
command.ExecuteNonQuery();
conn.Close();
this.GetData(tableName);
catch
throw;
And here is GetData procedure:
public void GetData(string tableNameString)
string tableName = tableNameString.Replace(" ", string.Empty);
command.CommandText = "Get" + tableName;
command.Parameters.Clear();
if (!StaticValues.dataSet.Tables.Contains(tableName))
StaticValues.dataSet.Tables.Add(tableName);
else
StaticValues.dataSet.Tables[tableName].Clear();
try
adapter.SelectCommand = command;
conn.ConnectionString = DAL.ConnectionString;
command.Connection = conn;
conn.Open();
adapter.Fill(StaticValues.dataSet.Tables[tableName]);
conn.Close();
catch
throw;
And this is my complete code for sql procedure:
USE [ISWM project]
GO
/****** Object: StoredProcedure [dbo].[UpdateExpenditureItems] Script Date: 13.04.2015 9:09:36 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER procedure [dbo].[UpdateExpenditureItems]
(@ID int,
@Name nvarchar(50),
@Parent nvarchar(50),
@Description nvarchar(50),
@IsGroup bit
AS
Begin
if @Parent IS NOT null
begin
declare @ParentID int
set @ParentID = (select ID from ExpenditureItems where Name=@Parent);
UPDATE ExpenditureItems SET Name =@Name, Parent =@ParentID, [Description] =@Description, IsGroup = @IsGroup WHERE ID=@ID;
end
else
begin
UPDATE ExpenditureItems SET Name =@Name, [Description] =@Description WHERE ID=@ID
end
end
The codes posted above work great in other similar parts of the application where select, insert, delete and update is required.
Concerning my current problem - I ran the procedure itself in SQL Server Management Studio, and it works well. I would say that there's something wrong with my c# code, but it can't be wrong because it's quite simple and works in other place in my application...
I really don't get what's missing...

Storedprocedure trigger using JDBC sender adapter.

Hi All,
How can i execute the storedprocedure using JDBC sender adapter. I need to trigger the storedprocedure once in every hour. so i would like to use the JDBC sender adapter. My question is what is the SQL i need use in the SQLstatement parameter..?? I don't want to send parameters and not expecting any return values. It should just trigger the procedure.
Thanks in adv.
Regards,

Hi Murali,
it is possible to execute a stored porcedure using a sender JDBC adapter.
Just Specify an SQL EXECUTE statement to execute a stored procedure, which contains exactly one SELECT statement.
This will have to be done for your SELECT statement in JDBC adapter. ALso, make the UPDATE as either TEST, if you dont want any updations or give an UPDATE statement for the UPDATE query.
Set the polling interval of your JDBC adapter to 1 hour and it will work like u want.

StoredProcedures Logical Unit of Work (Transactionality)

I haven't experimented yet about the bahaviour when calling multiple storedProcedures in a single XI-JDBC call.
When I call multiple stored procedures and if the transaction was partially successfull which means One storedProcedure call executed successfully and other failed in this scenario will this call treats as LUW and rolls back all the successful ones on the DB? or will be partial success?
Since the actual SQL commands are inside the storedprocedure how do we pass the exception/failed signal back to caller?
This is similar to calling insert/update statements using JDBC adapter I know that in this case each message call treats as LUW which means message will fail/rollback if any one of the statements failed.
Thanks in advance...
Laxman Molugu

Hai Ravi Charan
There are 3 types of LUW's available in SAP
1)Database Transaction or DBLUW
2)SAP      Transaction or SAPLUW
2)ABAP     Transaction or ABAPLUW
1) DBLUW : when it is called it locks the rows , Update the rows & commit the rows issued by auto Commit
2) SAPLUW : collection of Business reports is called SAPLUW and Issuing the Commit
here UPDATE,INSERT,MODIFY statements are valid
Commit work is given by Developer Side.
3) ABAPLUW : What ever Transaction Code we are creating is called ABAPLUW it is belongs upon Developers
here 3 types of updates available
1) Bundled Updates
2) Un-Bundled Updates
1) Bundled Updates :
    in Bundled Updates all your updates in a single unit of work present in a PERFORM 'XYZ'
PERFORM 'XYZ' on Commit.
here PERFORM-kept in Buffer 'XYZ' this form having all your update statements
Priarities of execution.
Perform xy on comit it will execute first
perform ab on comit it will execute second
I want to change this execution Order
Perform xy on comit Level 2 it will execute second
perform ab on comit Level 1 it will execute First
because it will depends on Level command
Using in Function Modules
Call Function XYZ in Update Task.
Commit work.
In this case it stores in a buffer once encounters the commit statement this will executes from the buffer
so it is an asynchronos method
2) Un Bundled Updates
these are two types
1) Inline Updates
2) Buffered Inline Updates
1) Inline Updates : INSERT,UPDATE
when update statement found in a program then it is called inline update and you should give the 'commit work'after a update statement
inthe inline update if you not issue a commit work the system will automatically issues the commit work.
2) Buffered Inline Updates:
you will buffer all your inline updates and executes after Encounter the 'COMMIT WORK'
100
   XYZ --> we can not roll back here
200
   ABC---> if here is using commit
Thanks & Regards

Urgent: ORA-24338: statement handle not executed

Hello,

C# code:
OracleConnection dbConnection = null; /* see finalize{} */
OracleCommand dbCommand = null;
OracleDataAdapter dbAdapter = null;
try
     dbConnection = new OracleConnection(GetConnectionString());
     dbConnection.Open();
     dbCommand = new OracleCommand();
     dbCommand.Connection = dbConnection;
     dbCommand.CommandText = "p3.p";                    dbCommand.CommandType = CommandType.StoredProcedure;
     dbCommand.Parameters.Add("p_c", OracleDbType.RefCursor, DBNull.Value, ParameterDirection.Output);
     dbAdapter = new OracleDataAdapter(dbCommand);
     System.Data.DataSet ds = new DataSet();
     dbAdapter.Fill(ds);
     return(ds);
catch (Exception e)
     Console.WriteLine(e.Message);
/*===================================================*/
Problem:
When code executes:
dbAdapter.Fill(ds);
I constantly get the ORA-24338.
The same result if I try from console with "set autoprint on" (v_c is defined beforehand):
SQL> execute p3.p(:v_c)
PL/SQL procedure successfully completed.
ERROR:
ORA-24338: statement handle not executed
It seems to me, that the problem is on the server.
Does anyone know, WHAT is the problem?
Thanks a lot beforehand!
Edgar.

In your procedure implementation (below), you forgot to assign the local variable v_c to the out parameter p_c before exiting the rountine. This means that the ref cursor parameter is never opened.
The error you got occurs because when ODP.NET gets back the ref cursor it tries to fetch from it without checking whether it's open or not. If you look up the ORA-24338 error code in the documentation, it'll tell you as much. Typcially, when I get an error I don't understand, I head straight for the docs. They not only tell me what it means, but often suggest a solution.
This behaviour of ODP must be for performance reasons, since doing the check everytime would be wasted most of the time. Still, it would have been nice if they'd emulated MSDAORA, which DOES check.
3 procedure p(p_c out t_c)
4 is
5 v_c t_c;
6 begin
7 open v_c for
8 select job_number
9 from rep_adhoc_invoices
10 where rownum<5;
11 end p;
12 end p3;
13
Frankly, I'm surprised you didn't get ORA-3113: end of communication channel. This is what happened to me when I exited a function without assigning the ref cursor. To solve it, I'd changed the declaration of the PL/SQL function and OracleCommand parameters to IN OUT instead of just OUT. THEN, I got ORA-24338. Anyway, watch out for these things as you progress.
Happy coding.
