Stored procedure modification breaks data refresh

Hello All,
I have a PowerPivot model that is based off of a number of views and stored procedures on SQL Server. The procedures and views work fine, but I'm at a point where the business users have requested modifications
that require changes (additions and deletions) of fields in these views and procedures. The views are easy to modify (I wrote select statements and selected field names rather than SELECT * ), but tedious since I have to write out all field names and do it
for each table based on a view.
The procedures are giving me more trouble, since the columns are not defined in the SQL calling the procedure. (Just procedure_name parameter1, ...). If I remove a column from the result set of the stored procedure,
refresh fails for the table fed by that procedure. When adding columns to the result-set, the new columns are not available after a normal refresh. I have to open the table itself and view the table properties. Re-saving the SQL calling the procedure seems
to be the trick for getting PowerPivot to recognize the new columns. These procedures are used in multiple workbooks.
The result of this is that I have to manually update each table in the model when I make a change like this. These views and procedures are used in multiple workbooks, making maintenance of this sort a chore.
I am using a workaround found here (http://social.msdn.microsoft.com/Forums/sqlserver/en-US/356cb739-37bd-4b43-a202-5b40ae171919/powerpivot-excel-2013-crashes-after-column-rename-in-source-datatabase?forum=sqlkjpowerpivotforexcel) to delete columns from
the stored procedure-fed tables. I manually delete the old column in PowerPivot before deleting it from the procedure.
So I am able to complete my work, but in a very circuitous manner. Is there some better way to update these tables and add/remove columns from the model?

I don't think you're going to find a better way. Versioning may help, by which I mean creating different views/procedures with versioned names (e.g. vwGetInfoV001) or some such thing then cloning the spreadsheets with the current version name available
in a documentation tab. At least that way you can gracefully upgrade without simply breaking the old while waiting to get all spreadsheets upgraded to the new.

SSRS - Oracle Stored procedure returns no data but does in SQL Developer Sudio

HI there,
Stored procedure returns no data when executed on the report but when i execute the stored procedure in Sql Developer it returns required rows.
Thanks for your help!

Hi Simon,
When i test with simple query, i get the data.
For your convenience, my stored proc looks lyk :
PROCEDURE pr_REPORT_data(P_STARTDATE IN DATE, P_ENDDATE IN DATE, data_rows OUT T_CURSOR) AS
OPEN completed_Reinstatement FOR
SELECT
value1,.......value5
FROM table1
WHERE
To_Date(createdDate, 'YYYY/MM/DD') BETWEEN To_Date(P_STARTDATE, 'YYY/MM/DD') AND To_Date(P_ENDDATE, 'YYYY/MM/DD');
END pr_REPORT_data;
T_CURSOR is of type cursor which is declared on the package.
I'm assuming the problem is with date parameters, however i converted the date before passing to
WHERE clause.

You need to have a Database Link between two servers. Then you could do execute that statement without any problem. Try to create a database link with the help of

Stored Procedure for displaying data in Crystal Reports

Hi I am new to Oracle & Crystal Reports,so can any one please give me sample stored procedure to display data in Crystal report from Oracle by passing rwo input values.

from site:-
Crystal Reports will only support the return of a single refcursor from Oracle. Even the latest and greatest version 10 doesn't allow you to return more than one recordset at a time. You could add one more step to your procedure that would join up the output of the multiple refcursors into a PL/SQL table and then fetch the result set out through a single refcursor. That way you are using temporary space that will be cleaned up as soon as the connection is terminated and will only be returning a single refcursor

Report Using A Stored Procedure Is Caching Data

Post Author: springerc69
CA Forum: Data Connectivity and SQL
I converted a report from a view that worked fine to a stored procedure to try and improve the performance of the report, but when I publish the report it seems to cache the data. When you change the parameters you use to call the report or simply run the report again with the original parameters the report doesn't run the sproc and just shows the cached data from the original request. If I right click on the report and select refresh (web based crystal report), it prompts for the parameters. I just close out the prompt window, report window and click on the link for the report again it returns the correct results based on the new parameters or a refresh based on the original parameters. I've checked the cache time setting and set it to 0, and if you close the Internet Explorer window that originally called the report, open IE back up and request the report it will return the appropriate data. I have also verify that the report is not setup to save data with report. This is on Crystal XI Server.

Which viewer are you using?
It might be that your IE settings are caching the report pages. because you're using an HTML viewer.
Try the Active-X viewer.
I've forgotten which icon it is that changes the viewer...it's under the preferences options, I think it's the one that looks like a hunk of cheese on the right upper side.

How to write stored procedure to spool data into file

Hi ,
We get differnt excel sheets of differnt products.
We upload data from excel sheet to database . After uploading data , I run Preprossor (sql script) to check the data
This preprocessor script contains several select statements that query different tables in database .the output is spooled into a cvs file .
I need to change this script into a stored procedure and spool the output to cvs file.
File spooling should be done inside the stored procedure so that if I call this stored procedure from java program ,or any concurrent program,its output is .cvs file and in parameter should be productname.
But inside the stored procedure , we cannot spool the data to some .cvs file . Is any way.I do not want to spool to file when calling.It should be inside stored procedure.
Or do I need to create a table and insert all the select statements output into it .
Here is the sample preprocessor script.
spool Graco_Product.csv
set head off
set feedback off
set Pagesize 100
SELECT '1. EVERY ASSEMBLY GROUP ADDED IN sys_PRODUCT TABLE MUST HAVE AT LEAST ONE ITEM IN WOC_ASSEMBLY_ITEM'

Calling Stored Procedure with a DATE input parameter

Hi. A question about Date input parameters when calling a stored procedure...
I have a procedure that takes a DATE parameter as input. I would like that DATE value to include a Time element.
My Application Module method takes an input parameter as java.util.Date (myParamDate) - which will preserve a time element(?).
However when I create the CallableStatement, I'm trying to set the parameter using setDate like this (for param 5):
            st = getDBTransaction().createCallableStatement("begin cs_my_pck.request_values(?,?,?,?,?,?,?,?); end;", 0);
            Connection myConn = st.getConnection();
            ArrayDescriptor myArrDesc = ArrayDescriptor.createDescriptor("CS_FIELD_TABT", myConn);
            Array sqlParamNameArray = new oracle.sql.ARRAY(myArrDesc, myConn, paramNames.toArray());
            Array sqlParamValueArray = new oracle.sql.ARRAY(myArrDesc, myConn, paramValues.toArray());
            Array sqlFilterNameArray = new oracle.sql.ARRAY(myArrDesc,myConn,filterNames.toArray());
            st.setString(1, repType);
            st.setObject(2, sqlParamNameArray);
            st.setObject(3,sqlParamValueArray);
            st.setObject(4,sqlFilterNameArray);
            java.sql.Date myRepDate = new java.sql.Date(myParamDate.getTime());
            st.setDate(5,myRepDate);
            System.out.println("Report Date = " + myRepDate.toString());
            st.setString(6,repUser);
            st.setString(7,repAttach);
            // set out param
            st.registerOutParameter(8, Types.NUMERIC);
            st.execute();I understand java.sql.Date does NOT include a Time element. But setDate() accepts only a java.sql.Date so my procedure parameter ends up with a zero time element.
How do I call this procedure retaining the Time element?
Thanks.

It includes time element, if you want more precision go with timestamp.

Can I use stored procedures to improve data retrieval from the database?

I have been requested to get multiple pieces of data from multiple tables and return the output in an array for use in a Java program.
Eliminating multiple calls to the database. Currently, the data is retrieved from the database in multiple steps but to eliminate
possible bottlenecks in the future, I created several complex sql statements.
For instance,
In the first table there are 20 columns of data. has a column named type which can have the one of these values: line, inn, or bsc
In the second table there are 6 columns of data. has the additional data for type line
In the third table there are 7 columns of data. has the additional data for type inn
In the fourth table there are 2 columns of data. has data regardless of type
etc...
Depending on a specific column value retrieved (inn) from the first table:
I need to collect all 20 columns in the first table and get all the columns in third table and the columns in the fourth table, etc.
Question: How can I remove the duplicate primary key columns without specifying for each table the column names to be returned?
I used the wildcard SELECT * because I didn't want to have to update the retrieval methods if additional columns are added to these
secondary tables.
example of my sql for type inn data:
select * from first_table f, third_table s, fourth_table t
where (f.column1='xxxx' and f.column2='xxxx') (the 'xxxx' are passed into the sql statement)
and
((s.column1=f.column1 and s.column2=f.column2)
and
(f.column3=t.column1));
Currently, I've duplicated the separate sqls for each valid type found in the first table (at least a dozen types). The only difference is
the table name. Instead of the third table I use the second table, etc.
The MAIN Question: How can I set this up to have one sql to handle each type? I want to eliminate having over a dozen duplicated sqls. Can I
incorporate this into a stored procedure or something? If so, how? Can anyone provide sample coding?
Your help is very much appreciated. Thank you.

Hi, Salah.
Use "Exec" in your query to run procedures.
SAPbobsCOM.Recordset oRS;
oRS = (SAPbobsCOM.Recordset)pCmp.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset);
oRS.DoQuery ("EXEC YourStoredProcName");

Stored Procedure w/ binary data parameter problems in Visual Basic

Howdy all.
I am having a problem calling stored procedures with a BLOB parameter. I have tried changing the paramater other data types to see if it would work, but with no success. I am calling the stored procedure from Visual Basic using ADO. I am using the Oracle ODBC Driver, Release 9.2.0.4.0. I have tried changing the setup of the ODBC a good bit because that has fixed several problems for me in the past; however, it did not fix my current problem.
Here is what I am trying to do. I have a function like the folowing:
<BEGIN --------------------------------------->
CREATE OR REPLACE FUNCTION PAGEFORMATSINSERT(
p_ObjectFormatCode_ID      IN RAW DEFAULT NULL,
p_PA_ID      IN RAW DEFAULT NULL,
p_Name      IN VARCHAR2 DEFAULT NULL,
p_FormatData      IN BLOB DEFAULT NULL,
p_PF_ID      IN OUT RAW )
RETURN INTEGER
AS
BEGIN
INSERT INTO PAGEFORMATS (PF_ID, ObjectFormatCode_ID, PA_ID, Name, FormatData) /* <---- this FormatData column is a BLOB column */
VALUES     (p_PF_ID, p_ObjectFormatCode_ID, p_PA_ID, p_Name, p_FormatData)
END PAGEFORMATSINSERT;
<END ----------------------------------------->
The FormatData parameter has a data type of BLOB. In my Visual Basic, I have my ADODB.Command object. I am setting the CommandText of the Command object to "{? = call PageFormatsInsert(?, ?, ?, ?, ?)}". In order to set the parameter value for the BLOB data type, I am calling the AppendChunk function of the Command object - passing it a Byte array.
I am getting the folling error:
     ERROR: -2147467259 [Oracle][ODBC][Ora]ORA-06550: line 1, column 13:
     PLS-00306: wrong number or types of arguments in call to 'PAGEFORMATSINSERT'
     ORA-06550: line 1, column 7:
     PL/SQL: Statement ignored
If I change the FormatData parameter to a LONG RAW parameter, I get the following error:
     ERROR: -2147467259 [Oracle][ODBC][Ora]ORA-06502: PL/SQL: numeric or value error: hex to raw conversion error
     ORA-06512: at line 1
I am at a loss as to how to get binary data into by Oracle database. I need to do it using stored procedures. How can I set up my stored procedure or table to do what I want it to do? Should I change my table definition? Are there some settings in the ODBC connection I can tweak? How can I get the stored procedure to accept my call from VB ADO?
Any help would be appreciated.
wally

Thanks for the idea, but I don't get how I am supposed to get my binary data to the stored procedure using the stream. I have a binary array that I want to pass to a stored procedure. I want to be able to use the same Visual Basic front end with out MSSQL database as with our Oracle database.
I am using the ADODB Connection and Command and RecordSet objects. Currenlty our front end calls the ADODB.Command(ParamNumber).AppendChunk function passing it the binary array. Somehow, the SQL Server driver does the magic in order for the MSSQL stored procedure to work correctly. I need to know how to do one of the following:
1. Get the Oracle driver to do the same magic.
2. Set up the Oracle stored procedure so I don't have to change the VB front end.
3. Change the VB front end so that it works with both MSSQL and Oracle.

Server stored procedure to convert date format before insert/ update

The source which has date in dd-MMM-yy format, have to convert it to
yyyy-mm-dd hh:mm:ss:SS and insert/update into the database using stored procedure.
ALTER PROCEDURE [dbo].[uspEmployeeData]
@emp_id char(35),
@emp_title varchar(64),
@start_date datetime
AS
BEGIN
SET NOCOUNT ON;
IF EXISTS (SELECT 1 FROM [dbo].[employee] WHERE emp_id= @emp_id)
BEGIN
UPDATE [dbo].[employee]
SET emp_title = @emp_tit,
start_date = @start_date
WHERE emp_id = @emp_id
END
ELSE
BEGIN
INSERT INTO [dbo].[employee](emp_id, emp_title, start_date)
VALUES ( @emp_id, @emp_title, @start_date);
END
"The input data for the field/parameter "e_date" is invalid according to the expected SqlDbType DateTime. ---> System.FormatException: The string '04-DEC-65' is not a valid AllXsd value.". Where and
how to convert the date format

Format() - new to SQL SERVER 2012 or later - allows you to format an input value to a character string based on a .NET format string, with an optional culture parameter:
ALTER PROCEDURE [dbo].[uspEmployeeData]
@emp_id char(35),
@emp_title varchar(64),
@start_date datetime
AS
BEGIN
SET NOCOUNT ON;
IF EXISTS (SELECT 1 FROM [dbo].[employee] WHERE emp_id= @emp_id)
BEGIN
UPDATE [dbo].[employee]
SET emp_title = @emp_tit,
start_date = Format(@start_date,'yyyy-mm-dd')
WHERE emp_id = @emp_id
END
ELSE
BEGIN
INSERT INTO [dbo].[employee](emp_id, emp_title, start_date)
VALUES ( @emp_id, @emp_title, Format(@start_date,'yyyy-mm-dd'));
END
Example:
SELECT FORMAT(getdate(),'d','en-us') AS us
SELECT FORMAT(getdate(),'d','de-DE') AS de
SELECT FORMAT(getdate(),'d','pt-BR') AS br

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.

Can I use an OLE DB Command Task to call a parameterized stored procedure, perform some data editing and pass variables back to the SSIS for handling?

I am using a Data Flow and an OLE DB Source to read my staged 3rd party external data. I need to do various Lookups to try and determine if I can find the external person in our database...by SSN...By Name and DOB...etc...
Now I need to do some more data verification based on the Lookup that is successful. Can I do those data edits against our SQL server application database by utilizing an OLE DB Command? Using a Stored Procedure or can I sue straight SQL to perform my edit
against every staging row by using a parameter driven query? I'm thinking a Stored Procedure is the way to go here since I have multiple edits against the database. Can I pass back the result of those edits via a variable and then continue my SSIS Data Flow
by analyzing the result of my Stored Procedure? And how would I do that.
I am new to the SSIS game here so please be kind and as explicit as possible. If you know of any good web sites that walk through how to perform SQL server database edits against external data in SSIS or even a YouTube, please let me know.
Thanks!

Thanks for that...but can I do multiple edits in my Stored Procedure Vaibhav and pass back something that I can then utilize in my SSIS? For example...
One and Only one Member Span...so I'd be doing a SELECT COUNT(*) based on my match criteria or handle the count accordingly in my Stored Procedure and passing something back via the OLE DB Command and handling it appropriately in SSIS
Are there "Diabetes" claims...again probably by analyzing a SELECT COUNT(*)
Am I expecting too much from the SSIS...should I be doing all of this in a Stored Procedure? I was hoping to use the SSIS GUI for everything but maybe that's just not possible. Rather use the Stored Procedure to analyze my stged data, edit accordingly, do
data stores accordingly...especially the data anomalies...and then use the SSIS to control navigation
Your thoughts........
Could you maybe clarify the difference between an OLE DB Command on the Data Flow and the Execute SQL Task on the Control Flow...
You can get return values from oledb comand if you want to pipeline.
see this link for more details
http://josef-richberg.squarespace.com/journal/2011/6/30/ssis-oledb-command-and-procedure-output-params.html
The procedure should have an output parameter defined for that
I belive if you've flexibility of using stored procedure you may be better off doing this in execute sql task in control flow. Calling sp in data flow will cause it to execute sp once for each row in dataset whereas in controlflow it will go for set based
processing

Sub report using Stored Procedure returns incorrect data

Post Author: rikleo2001
CA Forum: Data Connectivity and SQL
Guys,
I am using CR 9 in ASP.net application.
One simple report and one Sub report, sub report is basically linked with Stored procedure accepting one parameter and returns a select query.
Main report is linked with that sub report using that parameter field.
Sub report is on demand sub report.
Now when I execute that main report and click on on demand sub report I am getting Wrong order information.
Here is out put on main report
Order 1                                          on demandDetail
Order 2                                          on demandDetail
Order 3                                          on demandDetail
     NOW If I click on Order 3 (On demanddetail link, it displays rondom order details, some time correct on too), I am really stuck and don't know where I am going wrong.
Please help me to solve this issues.
Many Thanks

Hi Yangster,
Thank you so much for your reply.
On DEMAND Sub report is located in main report, IN DETAIL SECTION
I am passing Order ID from main report linked to {?morderid} in subreport under command object, and if I run it in design mode, it works perfectly alright, so problem is isolated to ASP.NET and Crystal report post back method on Crystal report.
The example I give to you this is a simple example to identify issues in my real application and report.
My main report contains summary of data base on unique identifier. that summary have 4 differant types of details which has to be on the same report (as Crystal report doesn't provide Nested subreport), so I decided to use 4 subreports on main report and all subreport using Stored procedure command object.(Sub report has it own complex processing requirement to fulfill).
Please help me with any further ideas? for the sample which I presented to you this is only using one SP on main report with a simple processing.
Many Thanks
