Performance of Stored procedures against Prepared Statements

What will be the exact difference in the performance between implementing stored procedures and prepared statements ?

Short answer: it depends.
There will probobaly be very little difference in performance difference for a sipmle insert / update etc.
Multiple inserts / updates etc you will probobaly find faster with a stored procedure rather than n prepared statments as you only have to contact the database once vs n times.
Hope this helps!

Help with calling stored procedure and preparing statement

hi guys help please..I want to call a procedure set the ResultSet to TYPE_SCROLL_INSENSITIVE and CONCUR_UPDATABLE in order for me to scroll thru the resultset from 1st row to end row and vice-versa..but currently, my code has an error becuase im hot sure on how to do this..Can you please help me guys to solve this? Thanks in advance!

Performance Tune Stored procedures

Hi Experts,
What is the best approach to performance tune stored procedures. Is it to run expalin plan for the queries used in cursors or there is more to it?
I need all your advise.
Thanks

As generic advice: Absolutely not.
The performance of PL/SQL may be irrelevant to the performance of specific SQL statements contained.
Consider the following:
1. A very inefficient query that runs one time and takes 2 seconds to execute.
2. A query that runs in 2 milliseconds inside a loop.
Which one is more likely to be the issue?
The answer is that it depends on the number of interations of the loop.
The proper tool for tuning PL/SQL, as discussed by Tom Kyte, are, depending on version, DBMS_PROFILER or DBMS_HPROF.
Find out where the time is being spent.
Then tune that which takes the most time.
It is not necessarily the slowest SQL statement.

ALDSP 3.0 -- schema owner for stored procedure or SQL Statement

Using ALDSP, I have a need to create a physical service based on a stored procedure or a SQL statement. I am wondering what will happen when I move to another deployment environment where the schema owner changes. In our QA and Prod environments, we have a different schema owner for all tables in the application (the DBAs believe this prevents unwanted updates to a prod environment). DSP elegantly supports this for normal table- and view-based physical services by mapping schemas through the DSP console after deployment. Will I get the same type of mapping capability for stored procedures and SQL statements? I noticed that I can add a SQL-based function to a physical service...is there a way to pass in the physical table name from that data service to the procedure or SQL statement?
Thanks,
Jeff

Schema name substitution should work for stored procedures just like it does for tables. If it doesn't - report a bug.
You don't get any help for sql-statement based data services - dsp doesn't parse the sql provided. One thing you could do is use the default schema (following the user of your connection pool), and not specify the schema in your sql-statement.

Sql server 2000 stored procs vs. prepared statements performance

Hi
I have observed that using stored procedure in sql server 2000 is much much faster than using a prepared statements. I had worked with oracle before and did not notice this much difference. I would like to use prepared statements or regular sql (for dynamic sql creation) in my apps. Does anyone have any suggestions ?.
thanks

Hi
FYI
I figured out the slowness problem in using prepared statement (db - sql server 2000)was due to the Microsoft typ4 4 jdbc driver. When I used the jdbc driver from atinav, my prepared statements worked as fast as stored procs.

JDBC Sender MSSQL Stored Procedure - Multiple Select Statements

Hello all,
I will proceed to tell you my problem, for which solution I request your kind advice:
Im working in a project for a retailer, which consists in sending the information from erp and sql server to pos thru XI interfaces.
One of the interfaces is about sending items from sql server to a file so the pos can load it into the system. For doing so I have devloped an stored procedure which function is to return several select statements as many stores the retailer might have, so they can have a different file per store along with its corresponding items in it.
The thing is that XI just gets the first select statement and creates the corresponding file, but it seems to ignore the remaining responses as I'm neither getting any file nor an error afterwards.
So, my question is: is XI capable of handling multiple select responses from an Stored Procedure in graphical mapping??? Or am I just wasting my time trying?
Thanks in advice for your help.
Regards.

Hello Ramkumar,
After 5 days trying, I finally made it work out applying your advice. Below the short explanation of what I did:
My Source structure is: Main Node->Row->Records (Material Number, StoreNum, Price, Status)
My Target structure is: Main Node->File Node->Record Node->Records ( Material Number, Price, Status)
The key was to make all the occurrences happen against StoreNum node. So, based on what you adviced these two where the key mappings:
1) The Mapping that will create a new file for each different store that comes in the query (In my case, query was already sort by store using an sql "order by" function, if not you can also use xi node function "sort" as Ramkumar suggested)
StoreNum->RemoveContext->SplitbyValue (Value Changed)->Collapse Contexts->File Node
2) The Mapping that will create each record in its corresponding store file:
StoreNum->RemoveContext->SplitbyValue (Value Changed)->Record Node
And Voilá !!! It worked.
Thanks very much Ramkumar.
Regards.

Return records from Stored Procedure to Callable Statement

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

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

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

Improve the performance in stored procedure using sql server 2008 - esp where clause in very big table - Urgent

Hi,
I am looking for inputs in tuning stored procedure using sql server 2008. l am new to performance tuning in sql,plsql and oracle. currently facing issue in stored procedure - need to increase the performance by code optmization/filtering the records using where clause in larger table., the requirement is Stored procedure generate Audit Report which is accessed by approx. 10 Admin Users typically 2-3 times a day by each Admin users.
It has got CTE ( common table expression ) which is referred 2 time within SP. This CTE is very big and fetches records from several tables without where clause. This causes several records to be fetched from DB and then needed processing. This stored procedure is running in pre prod server which has 6gb of memory and built on virtual server and the same proc ran good in prod server which has 64gb of ram with physical server (40sec). and the execution time in pre prod is 1min 9seconds which needs to be reduced upto 10secs or so will be the solution. and also the exec time differs from time to time. sometimes it is 50sec and sometimes 1min 9seconds..
Pl provide what is the best option/practise to use where clause to filter the records and tool to be used to tune the procedure like execution plan, sql profiler?? I am using toad for sqlserver 5.7. Here I see execution plan tab available while running the SP. but when i run it throws an error. Pl help and provide inputs.
Thanks,
Viji

You've asked a SQL Server question in an Oracle forum. I'm expecting that this will get locked momentarily when a moderator drops by.
Microsoft has its own forums for SQL Server, you'll have more luck over there. When you do go there, however, you'll almost certainly get more help if you can pare down the problem (or at least better explain what your code is doing). Very few people want to read hundreds of lines of code, guess what's it's supposed to do, guess what is slow, and then guess at how to improve things. Posting query plans, the results of profiling, cutting out any code that is unnecessary to the performance problem, etc. will get you much better answers.

Problem in Stored Procedure with DBMS_OUTPUT statement

Hi All,
I am facing a problem in the stored procedure.
In the stored procedure I am picking records from the table and displaying them in the screen using dbms_output.put_line statement. This works fine if my query fetches few records but in case of many records(84000 records) then the oracle application gets hanged.

1) How (if at all) does this relate to SQLJ/JDBC? I assume there is some relationship because of the forum you're posting to, so I'm trying to understand whether that relationship is germane to the problem you are having.
2) Why are you writing 86,000 rows of output to the dbms_output buffer? Why wouldn't your stored procedure return a REF CURSOR to your Java application and just have the Java application iterate through those rows?

Conversion failed when converting the varchar value ' + @websiteitems + ' to data type int.
and Im supplying the correct values of websiteitems (75530,75667,75518,75953) and Product.id is integer field, how do i supply when im using IN Statement

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules (you have no idea).
Temporal data should use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums.
This is not a correct schema design; can you fix this mess?
A procedure is named <verb>_<object>.
There is no such thing as a “category_id” in RDBMS! A column is “<attribute>_<attribute property>” but this is two <attribute property>'s without an <attribute>. This is like adjectives without a noun!
Using integers to encode the homepage categories is an awful design. Have you been to a library? Look at the Dewey Decimal Classification system. Noobs never bother to properly design encoding schemes; really hopeless noobs use IDENTITY!
Aren't websites named and not numbered? What integer did you use to get to this website? See the point?
There is no such thing as a generic “id” or “name” or "category" in RDBMS. Table names are collective or plural nouns to show us that they are sets.
We do not use flags in RDBMS, so your “publication_flag” and “deletion_flag” are both verbs (attributes are noun!) and a huge design flaw.
Finally, you have made one of the classic Noob errors that most people un-learn in 3rd or 4th week of SQL. You cannot past a string to IN() and expect that string to be parsed for you! Think about how silly that is and get a laugh at yourself. SQL is compiled,
not interpreted like 1960's BASIC!
Google my articles on the long parameter list for the procedure. But your real problem is an awful schema, improperly designed in both the DDL and data architecture.
Post the DDL and maybe we can fix it. But you need to get a book on basic data modeling as well as one on SQL.

JDBC performance calling stored procedures

Hi,
We have an java application which makes calls to PL/SQL stored procedures. We have one 'database server' component which handles all the database interaction, and other components which connect to it using CORBA.
The problem is that with everything running, certain queries are taking from 17 to 30 seconds to come back, but when you run the same sql from SQLPlus, you get the results back in about 2 seconds every time.
We're using a connection pool, but this doesn't seem to be the problem, as we put in diagnostics and it takes no time at all to get a free connection.
The time is taken up doing a getCursor() to get the result set back. We register the cursor as an output parameter, and open it from within the stored procedure.
Anyone any suggestions?
Thanks,
Neil.

Hi ,
You can call stored procedure using JPA (eclipselink API).Below is the sample code
ReadAllQuery readAllQuery = new ReadAllQuery(Employee.class);
call = new StoredProcedureCall();
call.setProcedureName("Read_All_Employees");
readAllQuery.useNamedCursorOutputAsResultSet("RESULT_CURSOR");
readAllQuery.setCall(call);
List employees = (List) session.executeQuery(readAllQuery);

Invoking stored procedures containing DML statements

Hi, I'm invoking a stored procedure that inserts the form record into the base tables, however I do not want to insert duplicates and if I try to do a count on that record from forms I get 0 records until the session is commited. I assume the insert was done in another session? is there a way around this? Thanks.

thanks, I found that the reason I was getting 0 records is because I'm calling a db package to insert the record using the on-insert trigger.. forms is only populating the table once I try to commit all the records bypassing my when-validate-record trigger.. so I now call my check_unique procedure from the insert procedure and raise an application exception from the db procedure...seems to work.
