Added new parm to an existing SQL stored procedure CR 11 doesn't like it

Hi
I have added a new parameter to an existing SQL stored procedure (SQL 2000). This stored procedure is currently being called from a Crystal XI report. It prompts for a date which works great. (The report was created with this parameter). I added a new parameter to the stored procedure. When I do a preview in Crystal, it prompts for the new parameter, but is NULL when I look at the SQL query and it brings back no data. If I try to verify the database, it tells me that I am missing parameter @ProcessType (varchar(5))--(name of new parameter). I have physically added this parameter to the crystal report with the select expert and still no luck. I have already tried renaming the procedure but am unable to update datasource location because of this parameter. The report is very detailed and I do NOT want to create a new report.

Unfortunately, I have tried and retried to do this. Nothing changes. I usually would get a message like database has changed, proceeding to fix report. I don't get this. It merely tells me database is up to date and only returns the 1 parameter, yet when I go to the datasouce and try to update it, it tells me that I have not supplied the new parameter.
I have tried everything, from closing Crystal reports and then going so far as to reboot my machine, just in case their was some kind of caching going on.
I have even asked other people I work with to look at it to make sure I am not doing something dumb...

Microsoft Visual Studio and SQL Server Reporting Services did not like this! When I added my dataset and parameters accordingly, my Dataset had no fields...almost as if running the Stored Procedure in the background to get its Metadata was not working. I
know this works because I tested it as a result of a straight EXEC Command. Why doesn't Microsoft Visual Studio and SQL Server Reporting Services not like this IF? I did end up getting around this by parameterizing the WHERE clause based on the @ReportTypeName
chosen.
WHERE (@ReportTypeName = 'HMO-POS New To HFHP - No Prior Year Member Spans'
AND (CHARINDEX('HMO',LTRIM(RTRIM([#TempTable_Distinct_Individual_Member_All_Info].[INDV Benefit Plan Name])),1) > 0

Hi ITBobbyP,
I have tested on my local environment and can reproduce the issue, the issue can be caused by the temp table you are using which will also cause the data not display.
I have use below sample table and record to have a test and details information below for your reference:
Right click the DataSet to select the "DataSet Properties" and click the query designer to execute the stored procedure by click the "!" to check if you can get the data:
If you got some error, the issue can be cause by the temp table invalid, so please make sure you have add the query to create and insert recored to temp table like below:
CREATE PROCEDURE vickytest0311_1
@ReportTypeName nvarchar(50)
AS
create table #VickyTest
column1 int,
column2 varchar(20)
insert into #VickyTest values (1,'Test1')
insert into #VickyTest values (2,'Test2')
insert into #VickyTest values (3,'Test3')
IF @ReportTypeName ='Test1'
BEGIN
select * from #VickyTest
where Column1=1
END
IF @ReportTypeName ='Test2'
BEGIN
select * from #VickyTest
where Column1=2
END
GO
3. I recommend you to not use the temp table and you will not need to add the create and insert statement in the stored procedure.
4. If you still got no data, please try to click the "Refresh fields" as below:
If you still have any problem, please feel free to ask.

Is i possible to base a report on a pl/sql stored procedure

Is i possible to base a report on a pl/sql stored procedure?
If Yes please give directions on how to do it.
/morten

Hello Morten,
In Reports 9i, with new feature JDBCPDS its possiable to create a report against a existing stored procedure.
Using JDBCPDS, user can access any JDBC-enabled data source. You can access database like Oracle, DB2, Sybase, ODBC Data Sources, etc using supporting
JDBC Drivers. User can also connect ODBC Data Sources like SQL Server, MS-Access, Excel etc.
User can create a JDBC Query angainst a SQL Query or Stored Procedure in any of mentioned dataSource.
Following is the syntax of the Oracle Stored Procedure, which can be used as Data Source with JDBCPDS.
Steps to create a JDBCPDS Report through Report Builder : http://otn.oracle.com:8877/reports/help/ - > JDBCPDS- > How To
//----------Package definition for Ref cursor ----------/
package test_Procedure as
type empcurProcedure5 is ref cursor;
end test_tryProcedure5;
// -----------Procedure definition ---------//
test_Procedure(p_emp_cv out test_tryProcedure5.empcurProcedure5,
p1 in NUMBER) is
begin
update emp set sal=sal + 50 where deptno > P1
open p_emp_cv for select * from emp where deptno > P1;
end test_Procedure;
Procedure first parameter will be Ref Cursor and will be used to return the resultSet to JDBC Query.
User should create first this procedure in Database. Then in JDBC Query Dialog, user can call this stored procedure by specifying procedure name.
test_Procedure(40)
Please see ORACLE_HOME/reports/conf/jdbcpds.conf for more Connection and
JDBC-Driver information.

How to send a Varying Array param to a PL/SQL Stored Procedure from Java

* I am VERY new to jdbc, and even somewhat new to Java
* I'm using Java 1.5, Oracle 10g.
* I need to call the following PL/SQL Stored Procedure from Java:
procedure setEventStatus
i_deQueueStatus in deQueueStatus_type
*deQueueStatus_type is the following (an array of deQueueStatus_OBJ):
CREATE OR REPLACE TYPE deQueueStatus_OBJ as object
eventID number (20),
dequeuestatus varchar2(20)
CREATE OR REPLACE TYPE deQueueStatus_TYPE IS VARYING ARRAY(500) of deQueueStatus_obj
*I have created a Java object as follows:
public class EventQueueDeQueueStatus
     long      eventID;
     String      dequeueStatus;
     EventQueueDeQueueStatus(long eventID, String dequeueStatus)
          this.eventID = eventID;
          this.dequeueStatus = dequeueStatus;
I have an ArrayList of these.
I need to pass this list to the Stored Procedure. How do I create a java.sql.Array so I can call CallableStatement.setArray to set the parameter? Or do I use something else? I have tried setObject with both the ArrayList and also with a primitive array, but got "Invalid Column Type" both times.
Any help would be greatly appreciated. I just got this task today, and I have to make it work by Tuesday :-( !
Thanks,
Kathy

Kathy,
Search the archives of this forum and the JDBC forum for the terms STRUCT and ARRAY and you can find some sample code on the JDBC How-To Documents page and the JDBC Samples which can both be accessed from this page:

APEX - accepting OUT variable values from PL/SQL Stored Procedure

I have created a page (Form) which is accepting values text fields.
In the Page Processing section under Processing, I am passing the values to a PL/SQL Stored Procedure, which acts like an API. The procedure contains code to validate the entered data and finally insert the data into the base tables. The procedure also contains OUT variables in the parameter that would return status of processing and any error messages.
Now, my question is, how can I make the page accept these OUT variables from the procedure. What I wish to do is, to capture these messages/processing status from the procedure in the page. For example, if there is a error in the data and the procedure is sending this message in the OUT variable, I need this to be displayed on the page as an error message.
Is this possible in APEX?
Regards,
Santhosh Jose

Hi VC,
I just tried putting the string directly instead of the variable. Its still not giving me the expected results.
HOWEVER, I think the reason was because of the EXCEPTION block in my code. I have an EXCEPTION block to handle exceptions. I commented the WHEN OTHERS section and now the error message is coming on the page.
So what I have done now is as follows: At the point at which the error is expected, I am raising a handled exception. And within the exception handling, I am giving RAISE_APPLICATION_ERROR.
WHEN ex_main_error*
THEN*
p_status := 2;*
p_msg := 'ERROR Stage: '||lc_err_stage||' ERROR Message: '||lc_err_msg;*
RAISE_APPLICATION_ERROR (-20001, p_msg);*
This is working now! Which is very good news. Thanks once again for your help!

How to create an External Content Type with SQL Stored Procedures Parameters and query it in a SharePoint App

Hi,
I'm new to SharePoint 2013 I want to be able to query a MSSQL database from a SharePoint App I have tried to create an External Content Type (ECT) which is produced from a MSSQL stored Procedure, this procedure has several parameters which are needed to
filter the data correctly. From here I want to produce an external list which I can then query from a c# SharePoint app. If I leave the filters in the ECT null then the list is of course empty or if enter a default values the results are limited
for the app to query so are no good.
I want to dynamically pass values to the ECT when querying from the app, is this not possible. Should I just be returning everything in an external list and then letting the query in the app filter the data, this seems inefficient?
Is this the best way to do this or should I be doing this differently?
Please can someone point me in the right direction.
Thanks

Hi Pandra801,
When you create a the external content type, please try to add a filter based on your select statement.
http://arsalkhatri.wordpress.com/2012/01/07/external-list-with-bcs-search-filters-finders/
Or, try to create a stored procedure based on your select statement, then create ECT using the SQL stored procedure.

MS SQL Stored Procedure problem

Hi,
I am using BO XI R2, Crystal Report XI and MS SQL Database.
I found a strange error when generating the report using my java application if the crystal report is using MS SQL stored procedure. The error encountered :
com.crystaldecisions.sdk.occa.managedreports.ras.internal.a: Cannot open report document. --- Custom table prefix specified in the InfoStore does not exist. This is a configuration problem. Please contact your system administrator.
cause:com.crystaldecisions.sdk.occa.report.lib.ReportSDKServerException: Custom table prefix specified in the InfoStore does not exist. This is a configuration problem. Please contact your system administrator.---- Error code:-2147467259 Error code name:failed
detail:Cannot open report document. --- Custom table prefix specified in the InfoStore does not exist. This is a configuration problem. Please contact your system administrator.
This is when the code executed is:
reportClientDocument = reportAppFactory.openDocument(report, 0, Locale.ENGLISH);
If the report does not use the stored procedure, it's ok.
If i run the report (with stored procedure) from CMC using the default table prefix (in database config tab), it's able to generate the report.
If i select custom table prefix and specify the custom table prefix value with the same value as in the default table prefix, it could not generate the report and error stated that the table could not be found.
Please enlighten me if you have use MS SQL database for reporting with BO XI R2.
Thanks.

That means it's not a SDK-specific error.
Once it's resolved in InfoView, it'll likely be resolved with your app.
You might want to open a support case with SAP.
Sincerely,
Ted Ueda

Actuate 7 PL/SQL Stored Procedure Call Before the Report Run.

Hi,
I need a small help to call a pl sql stored procedure in actuate 7.
I wrote a code a on component content
Function runProc(procName as String, connection As AcDBConnection )
' Insert your code here
Dim statement As AcDBStatement
Dim results as string
' Prepare statement
Set statement = connection.Prepare("BEGIN " & procName & "; END;" )
If statement Is Nothing Then
results = "Failed to prepare statement."
results = results & " " & connection.GetSpecificErrorText( )
results = results & " " & connection.GetGeneralErrorText( )
Exit sub
End If
' Execute sprocoutparam
If statement.Execute() = 0 Then
results = "Stored procedure " & procName & "execution failed."
results = results & " " & connection.GetSpecificErrorText( )
results = results & " " & connection.GetGeneralErrorText( )
Else
results = "Stored procedure " & procName & " execution success."
End if
ShowFactoryStatus(results)
End FunctionNow this Code I am calling on the Chart Start Method
Sub Start( )
    Super::Start( )
    ' Insert your code here
    Dim ProcName as String
    Dim connectionObject As AcDBConnection
    ProcName="DELETECUSTOMER(1234)"
    runProc(ProcName, connectionObject )
End SubNow when i Run the Report i get this Error !
NewReportApp::Frame::Chart%Start(9): Invalid procedure reference. - (runProc)
1 Semantic Error(s) found
Thanks,
Asif

hi,
Finally Figured Out Here....
Steps to Call the Stored Procedure In Actuate 7
1 – Right Click on Content – Frame and go to properties and method Tab.
     1 – Click on New Button to you create own custom method.
     2 – Write the following code :
Sub runProc(procName as String, connection As AcDBConnection )
     Dim statement As AcDBStatement
     Dim results as string
     Set connection = GetConnection()
     'Prepare statement
     Set statement = connection.Prepare("BEGIN " & procName & "; END;" )
          If statement Is Nothing Then
               results = "Failed to prepare statement."
               results = results & " " & connection.GetSpecificErrorText( )
               results = results & " " & connection.GetGeneralErrorText( )
               MsgBox "Procedure Not Called....Badddddd"
               Exit sub
          End If
     ' Execute sprocoutparam
          If statement.Execute() = 0 Then
               results = "Stored procedure " & procName & "execution failed."
               results = results & " " & connection.GetSpecificErrorText( )
               results = results & " " & connection.GetGeneralErrorText( )
               MsgBox "Procedure Not Called....Badddddd" & results
          Else
               results = "Stored procedure " & procName & " execution success."
               MsgBox "Procedure Called....Wowwww"
          End if
          ShowFactoryStatus(results)
End Sub2 – Now let call the stored procedure before our actual report query runs.
     1 - Right Click on Content – Frame and go to properties and method Tab.
     2 - Select the Start Method and Click on Override button.
     3 - Write the following code:
Sub Start( )
     Dim ProcName as String
     Dim connectionObject As AcDBConnection
     Set connectionObject = GetConnection()
     ProcName="XXTEST ()"
     runProc( ProcName, connectionObject )
    Super::Start ( )
End Sub3 – Now design your report as usual using the Textual Query window.

Big PL/SQL stored procedure optimization.

Hi There,
Can any one let me the basic steps for optimization or tuning of a PL/SQL stored procedure for better performance.
DB: 11.2.0
OS: Solaris 10
looking forward.
Regards,

>

Seriously - how do you expect anyone to give you any specific things to do when you don't provide any specific information about your procedure?
A procedured is comprised of one or more steps. So to tune it you need to determine which steps are 'slow' and make them 'fast'! ;)
There are several common causes of performance problems with PL/SQL are:
1. Using PL/SQL when SQL should have been used. Don't use PL/SQL to begin with - always use SQL unless it just can't do the job required. The 'PL' in PL/SQL means 'Procedural Language' and should be used for transactional (multi-step) processing or when 'procedural' operations are needed that aren't available in SQL.
2. Using slow-by-slow (row by row) processing instead of BULK processing.
3. Using multiple nested LOOPs when a more complex query could have allowed a single loop to be used.
4. Using COMMITs more frequently than required. Search this forum and you will find far too many questions about how to do a COMMIT after 10,000 rows (or some other number). A COMMIT should be performed AFTER a transaction has been completed, not during the middle of it. Frequent commits generally use more resources, degrade performance and risk the famous 'snapshot too old' message.
The very first step of performance 'tuning' is to first verify that any 'tuning' is even required. Too many people suffer from CTD - compulsive tuning disorder.
The second step is to identify what step, or steps, of the process are performing below par.
Which means the best developers are proactive - they plan ahead.
1. Create an explain plan BEFORE the code goes to production. Once the code has been tested and believed to perform properly an execution plan should be created and SAVED for future reference. That saved plan can then be used later, when you suspect a performance issue, to detect changes that might have affected performance: create a new plan and compare it to the baseline.
2. Create explains for ALL key queries. As suggested by step #1 performance is all about comparison: performance 'now' COMPARED TO performance 'then'. If the don't know the performance 'then' it can be difficult to know if the performance has changed. If a query has a 'now' execution time of 2 minutes is that 'fast' or 'slow'? Well - compared to WHAT? You can't know 'fast' or 'slow' if you don't know 'then' and 'now'. How fast was it yesterday, last week or last month?
3. Instrument your procedural code. That means measure, for EACH STEP, how long it took to execute and how much data it worked with. That information needs to be logged. Your logging and data collection can be static (it ALWAYS happens) or dynamic. Oracle's own code is HEAVILY instrumented. Some operations and activity are always logged and available in the data dicitionary views or various performance reports such as AWR.
Other operations, such as the extended trace facility, only collect data on request.
IMHO your first step should be to begin the 'proactive' steps above.

I've been messing around with XML and XSQL in particular. I was trying to write a xsql page to display a report with account totals...I have the following .xsql which calls a PL/SQL stored procedure :
<?xml version="1.0"?>
<xsql:query connection="pfcdm" xmlns:xsql="urn:oracle-xsql">
<xsql:set-session-param name="zasset_total" value="100">
<xsql:dml connection="pfcdm">
rraman.sp_vw_id(zasset_total,zinvm_total,zmkt_val);
</xsql:dml>
</xsql:set-session-param>
select 'Asset total is {@zasset_total}' as "ASSET_TOTAL" from dual
</xsql:query>
My procedure sp_vw_id returns the values that it should. But, I am not sure how to declare variables within a page, and to output the return values. There is very scanty documentation on the usage of <xsql:dml> or <xsql:ref-cursor-function>.
Any response would be greatly appreciated.
Thanks,
Raja

Here is the example from the Oracle9i (complete rewrite) of the XSQL Chapter in our Oracle documentation.
Question
I using <xsql:dml> to call a stored procedure which has one OUT parameter, but I was not able to see any results. The executed code results in the following statement:
<xsql-status action="xsql:dml" rows="0"/>
Answer
You cannot set parameter values by binding them in the position of OUT variables in this release using <xsql:dml>. Only IN parameters are supported for binding. You can create a wrapper procedure that constructs XML elements using the HTP package and then your XSQL page can invoke the wrapper procedure using <xsql:include-owa> instead.
For an example, suppose you had the following procedure:
CREATE OR REPLACE PROCEDURE addmult(arg1 NUMBER,
arg2 NUMBER,
sumval OUT NUMBER,
prodval OUT NUMBER) IS
BEGIN
sumval := arg1 + arg2;
prodval := arg1 * arg2;
END;You could write the following procedure to "wrap" it, taking all of the IN arguments that the procedure above expects, and then "encoding" the OUT values as a little XML datagram that you print to the OWA page buffer:
CREATE OR REPLACE PROCEDURE addmultwrapper(arg1 NUMBER, arg2 NUMBER) IS
sumval NUMBER;
prodval NUMBER;
xml VARCHAR2(2000);
BEGIN
-- Call the procedure with OUT values
addmult(arg1,arg2,sumval,prodval);
-- Then produce XML that encodes the OUT values
xml := '<addmult>'| |
'<sum>'| |sumval| |'</sum>'| |
'<product>'| |prodval| |'</product>'| |
'</addmult>';
-- Print the XML result to the OWA page buffer for return
HTP.P(xml);
END;This way, you can build an XSQL page like this that calls the wrapper procedure:
<page connection="demo" xmlns:xsql="urn:oracle-xsql">
<xsql:include-owa bind-params="arg1 arg2">
BEGIN addmultwrapper(?,?); END;
</xsql:include-owa>
</page>This allows a request like:
http://yourserver.com/addmult.xsql?arg1=30&arg2=45
to return an XML datagram that reflects the OUT values like this:
<page> <addmult><sum>75</sum><product>1350</product></addmult>
</page>

PL/SQL Stored procedures vs C# code.

Hi All
We are going to start designing a kind of transactional application with huge volume of data (150 million records per month). Our selected DB engine is Oracle 10.g while C# is selected development language.
Because of big volume of data performance is one of the most important factors for us, and the technical design should gain the best level of performance.
What i'm looking for and studing for it is to define which kind of operation shall be done by Stored Procedure which will be written by PL/SQL or by C# classes?
I don't interested in to handle complicated and complex jobs using PL/SQL stored procedures while the performance really deserve it.

Hello,
Well, my philosophy is to leverage the database as much as possible. I have worked with applications that had no "select", "insert", "update" or "delete" statements in them. Instead, stored procedures and functions inside of PL/SQL packages and bodies were used. Some people will argue strongly against that, but I belong to the "thick database" group rather than the "the database is just a persistence layer that I have to deal with" group. To me it makes sense to co-locate the code that works on the data with the data. If you are working with large volumes of data, I find the bulk operations available via PL/SQL to be very handy.
Here's an AskTom thread that deals with this general issue:
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:12083187196917
Whilst the thread is primarily about Java, you can substitute just about any other language and the meaning will still carry over.

Mark

How to bind arrays to PL/SQL stored procedure using OCI?

Hi,
We are having problems trying to bind arrays to PL/SQL stored procedure using OCI. Here is the situation:
- We have a stored procedure called "GetVEPFindTasks" with the following interface:
PROCEDURE GetVEPFindTasks (
p_ErrorCode OUT NUMBER,
p_ErrorMsg OUT VARCHAR2,
p_RowCount OUT NUMBER,
p_VEPFindTasks OUT t_VEPFindTaskRecordTable,
p_MaxTask IN NUMBER);
t_VEPFindTaskRecordTable is a record with the following entries:
TYPE t_VEPFindTaskRecord IS RECORD (
RTCID NUMBER,
TransNum NUMBER,
TransTimestamp VARCHAR2(20),
Pathname1 image_data.pathname%TYPE,
Pathname2 image_data.pathname%TYPE,
Pathname3 image_data.pathname%TYPE,
OperatorID operator.id%TYPE);
- Now, we are trying to call the stored procedure from C++ using OCI (in UNIX). The call that we use are: OCIBindByName and OCIBindArrayOfStruct to bind the parameters to the corresponding buffers. We bind all parameters in the interface by name. Now, we do bind the record's individual item by name (RTCID, TransNum, etc.), and not as a record. I don't know if this is going to work. Then, we use the bind handles of the binded record items (only record items such as RTCID, TransNum, and NOT error_code which is not part of the record) to bind the arrays (using OCIBindArrayOfStruct).
All of the parameters that are binded as arrays are OUTPUT parameters. The rest are either INPUT or INPUT/OUTPUT parameters. Now, when we try to execute, OCI returns with an error "Invalid number or types of arguments" (or something to that sort... the number was something like ORA-06550). Please help...
Is there any sample on how to use the OCIBindArrayOfStruct with PL/SQL stored procedures? The sample provided from Oracle is only for a straight SQL statement.
Thank's for all your help.

As you said:
You have to pass in an array for every field and deconstruct/construct the record in the procedure. There is no support for record type or an array of records. Can you give me a example? I'am very urgently need it.
thanks
