Stored Procedure vs Views, Please clearify.

Hi Gents,
I am working on client side as a crystal report developer, the client has several applications linked to each other by some means and each application has its own database. They have created a common database called Reporting Layer, the database consists of only stored procedures, that is the stored procedures are collecting data from all the databases and making up a dataset. Now I need to develop reports using these stored procedures. Consider these stored procedures as tables for now.
If you have got the basics, here is my concern about using stored procedures for the reports.
Example : Say I need to refer 3 stored procedures for my report to get the required data then I need to call or attach all the three stored procedures with crystal and link them properly to get the required data. The question here is, say I need only 2 columns from each stored procedure then I simply drag the columns needed and drop on the reports...!!!
So if I had a view instead of a stored procedure then I could refer 3 views in the command object or might have written a stored procedure to return the results containing only the columns the report is ment for.
Select v1.a, v1.b, v2.a, v2.b, v3.a, v3.b from v1,v2,v3 where v1.id = v2.id and v1.id = v3.id
or
Select v1.a, v1.b, v2.a, v2.b, v3.a, v3.b from v1 inner join v2 on v1.id = v2.id inner join v3 on v1.id = v3.id
I want to explain this to my client and ask them to convert all the stored procedures to views, please suggest what can I tell them ? And if you think that the method my client has opted that is of stored procedures is better than views then please explain in this scenario.
Thanks
-Azhar

Hi Azhar,
Not sure if you are in the right place, you would likely get a better description if you post your question to the Forums for which ever DB server you are using. They likely have more detailed info on the efficiencies of each.
For Crystal Reports one possble scenario with using multiple Stored Proceedures (SP) is that each SP would or should be in it's on subreport. Unless you can link them, this will cause the SP to run each time that section is hit. Worst Example is if you put the subreport in the detail section for every record returned the subreport would run. If in the group header for each Group header condition met the subreport would run.
Using them in a Command Object would work but not that efficient and would be better if you used one SP to get the data or use a database to save all the data into as you suggested and report directly off of it.
As for the amount of data the SP returns CR may only ask for the fields used, depends on a few conditions, or it may have to get all of the data and filter out just the fields used in the report. Could be a big delay waiting for the SP to run and/or client side data filtering.
As for Views all the data collection is done server side, same as an SP, but only one view would be required. Or you may want to create specific SP's for use in the reports and not use Command Objects but simply drop the SP into the Database Wizard as the data source. This way all data collection is done server side which is much more efficient and CR at filtering data.
CR does not care if you use Views or SP's, we are simply sending the SQL to the server and waiting for the results. Which one is more efficient is more for that DB forum to answer.
Hope this helps
Don

Do you still have the Apply MRU process running? I assume you do because otherwise you wouldn't receive the error message. Is the process you are talking about running before the Apply MRU process? It seems it does. Try chaning the execution sequence and run this process after the automatic MRU process.

Can someone help me diagnose a strange stored procedure performance issue please?

I have a stored procedure (posted below) that returns message recommendations based upon the Yammer Networks you have selected. If I choose one network this query takes less than one second. If I choose another this query takes 9 - 12 seconds.
/****** Object: StoredProcedure [dbo].[MessageView_GetOutOfContextRecommendations_LargeSet] Script Date: 2/18/2015 3:10:35 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].[MessageView_GetOutOfContextRecommendations_LargeSet]
-- Parameters
@UserID int,
@SourceMessageID int = 0
AS
BEGIN
-- variable for @HomeNeworkUserID
Declare @HomeNeworkUserID int
-- Set the HomeNetworkID
Set @HomeNeworkUserID = (Select HomeNetworkUserID From NetworkUser Where UserID = @UserID)
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON
-- Begin Select Statement
Select Top 40 [CreatedDate],[FileDownloadUrl],[HasLinkOrAttachment],[ImagePreviewUrl],[LikesCount],[LinkFileName],[LinkType],[MessageID],[MessageSource],[MessageText],[MessageWebUrl],[NetworkID],[NetworkName],[PosterEmailAddress],[PosterFirstName],[PosterImageUrl],[PosterName],[PosterUserName],[PosterWebUrl],[RepliesCount],[Score],[SmallIconUrl],[Subjects],[SubjectsCount],[UserID]
-- From View
From [MessageView]
-- Do Not Return Any Messages That Have Been Recommended To This User Already
Where [MessageID] Not In (Select MessageID From MessageRecommendationHistory Where UserID = @UserID)
-- Do Not Return Any Messages Created By This User
And [UserID] != @UserID
-- Do Not Return The MessageID
And [MessageID] != @SourceMessageID
-- Only return messages for the Networks the user has selected
And [NetworkID] In (Select NetworkID From NetworkUser Where [HomeNetworkUserID] = @HomeNeworkUserID And [AllowRecommendations] = 1)
-- Order By [MessageScore] and [MessageCreatedDate] in reverse order
Order By [Score] desc, [CreatedDate] desc
ENDThe Actual Execution Plan Shows up the same; there are more messages on the Network that is slow, 2800 versus 1,500 but the difference is ten times longer on the slow network.Is the fact I am doing a Top 40 what makes it slow? My first guess was to take the Order By Off and that didn't seem to make any difference.The execution plan is below, it takes 62% of the query to look up theIX_Message.Score which is the clustered index, so I thought this would be fast. Also the Clustered Index Seek for the User.UserID take 26%which seems high for what it is doing.
I have indexes on every field that is queried on so I am kind of at a loss as to where to go next.
It just seems strange because it is the same view being queried in both cases.
I tried to run the SQL Server Tuning Wizard but it doesn't run on Azure SQL, and my problem doesn't occur on the data in my local database.
Thanks for any guidance, I know a lot of the slowness is due to the lower tier Azure SQL we are using, many of the performance issues weren't noticed when were on the full SQL Server, but the other networks work extremely fast so it has to be something to
with having more rows.
In case you need the SQL for the View that I am querying it is:
SET QUOTED_IDENTIFIER ON
GO
CREATE VIEW [dbo].[MessageView]
AS
SELECT M.UserID, M.MessageID, M.NetworkID, N.Name AS NetworkName, M.Subjects, M.SubjectsCount, M.RepliesCount, M.LikesCount, M.CreatedDate, M.MessageText, M.HasLinkOrAttachment, M.Score, M.WebUrl AS MessageWebUrl, U.UserName AS PosterUserName,
U.Name AS PosterName, U.FirstName AS PosterFirstName, U.ImageUrl AS PosterImageUrl, U.EmailAddress AS PosterEmailAddress, U.WebUrl AS PosterWebUrl, M.MessageSource, M.ImagePreviewUrl, M.LinkFileName, M.FileDownloadUrl, M.LinkType, M.SmallIconUrl
FROM dbo.Message AS M INNER JOIN
dbo.Network AS N ON M.NetworkID = N.NetworkID INNER JOIN
dbo.[User] AS U ON M.UserID = U.UserID
GO
The Network Table has an Index on Network ID, but it non clustered but I don't think that is the culprit.
Corby

I marked your response as answer because you gave me information I didn't have about the sort. I ended up rewriting the query to be a join instead of the In's and it improved dramatically, about one second on a very minimal Azure SQL database, and before
it was 12 seconds on one network. We didn't notice the problem at all before we moved to Azure SQL, it was about one - three seconds at most.
Here is the updated way that was much more efficient:
CREATE PROCEDURE [dbo].[Procedure Name]
-- Parameters
@UserID int,
@SourceMessageID int = 0
AS
BEGIN
-- variable for @HomeNeworkUserID
Declare @HomeNeworkUserID int
-- Set the HomeNetworkID
Set @HomeNeworkUserID = (Select HomeNetworkUserID From NetworkUser Where UserID = @UserID)
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON
;With cteMessages As
-- Begin Select Statement
Select (Fields List)
-- Join to Network Table
From MessageView mv Inner Join NetworkUser nu on MV.NetworkID = nu.NetworKID -- Only Return Networks This User Has Selected
Where nu.HomeNetworkUserID = @HomeNeworkUserID And AllowRecommendations = 1
-- Do Not Return Any Messages Created By This User
And mv.[UserID] != @UserID
-- Do Not Return The MessageID
And mv.[MessageID] != @SourceMessageID
), cteHistoryForThisUser As
Select MessageID From MessageRecommendationHistory Where UserID = @UserID
-- Begin Select Statement
Select Top 40 (Fields List)
-- Join to Network Table
From cteMessages m Left Outer Join cteHistoryForThisUser h on m.MessageID = h.MessageID
-- Do Not Return Any Items Where User Has Already been shown this Message
Where h.MessageID Is Null
-- An Order By Is Needed To Get The Best Content First
Order By Score Desc
END
GO
The Left Outer Join to test for null was the biggest improvement, but it also helped to join to the NetworkUser table instead of do the In sub query.

hello ive an assignment due but ive hit a brick wall, would anyone be as kind to help me?
ShareTraders LTD is an online share brokerage which allows its customer to trade shares on the US stock market. Customers can either sell or buy shares – the sales price depends on the curently quoted prices in the share table. The below ERD
shows a section of their database that refers to their customers who trade shares online.
Funds are categorised into different categories.
Customers may limit their exposure to a particular category of fund.
Customers fund their share purchases through funds.
Customers may limit their exposure to a particular category of fund.
Shares are grouped into different categories.
Customer trades are tracked in their portfolios.
The shares that the customer’s trade are recorded in their portfolios.
Staff are authorised to change the share prices of particular categories of shares.
Staff are authorised to change the share prices of particular categories of shares.
TSQL à Stored procedure
Create a stored procedure (call it
Assign1) which will
insert a purchase of shares into the CustomerPortfolioTBL for a customer. The data that will be passed to the stored procedure is: the CustomerID, the ShareID, and the TransactionAmount.
The data for the other columns in the CustomerPortfolioTBL will be got as follows
TransactionID
à make sure that this column is an identity column which will automatically generate the next TransactionID.
TransactionType – this column will be filled by your sproc with the word “Purchase”.
SharePrice
à the price will be read from the share SellPrice column in the ShareTBl for that ShareID.
TransactionDate
à this column will be filled by your sproc with todays date
à use the GetDate() function.
Business Requirement
Customers are not allowed to purchase more than 5 times in the current month. Your sproc must therefore:-
Count the number of purchases the customer has made this month
à use the Month() and the GetDate() functions.
If the no of purchases is greater than or equal to 5 your sproc must send an error message of “Sorry
purchase is refused 5 purchases have been made this month”
Customers cannot spend over their exposure limit for a particular share category – get this from the CustomerExposureTBl. Your sproc must therefore:-
Read in to an internal variable the exposure limit from the CustomerExposureTBl for the inputted CustomerID.
Add up all the transaction amount of shares that the customer has purchases (TransactionType = purchase) for shares whose category is the same as the share
being purchased). Put this calculation into an internal variable.
Add up all the transaction amount of shares that the customer has sold (TransactionType = sale) for shares whose category is the same as the share being
purchased). Put this calculation into an internal variable.
iv)
If ((Total Purchases
of share in this category – Total Sales of share in this category) + TransactionAmount) is greater than exposure limit your sproc
must send an error message of “Sorry purchase is refused Exposure limit is breached”

Decrypt the Encrpted Stored procedure and views

Hi,
Anybody can help me, how to decrypt the encrypted stored procedure in SQL server.?

They are not encrypted. They are obfuscated. ApexSQL can show you the source code with the wink of an eye.
But before you do that - if this is a vendor application, check your license agreement.

How to use arrays in stored procedure??Please do help me.......

hi, i need to make a procedure where i may execute a query.The query returns multiple rows.Now i want to use 1 row.i needs to fetch all colums as out parameter...can anyone please help me.....i will be very thankful to the person.

you cannot just force only one column from a select statement to be a out parameter, you need to collect all the columns into a collection type and use the collection type as out parameter or use refcursor as out parameter and fetch the rows
using collection type
create type obj_typ is object(
a_val number,
b_val varchar2(100)
create type nest_typ is table of obj_typ
create or replace procedure retrieve_emp(mgr_no number,e_details out nest_typ) is

Should i have to add any TimeOut Command in my Sql Stored Procedure. If please suggest me.
Thanks in advance.

Time out is the client who throws the error not SQL Server. Please read Erland's article

Function of 'Declare' in Stored Procedure statements

Dear Readers,
Can someone tell me what is the difference when we use Declare and don't use declare in the create stored procedure statement. Please see below:
Create proc education
AS
Declare @name varchar(20)
Select @name='John'
GO
When I run this store procedure nothing is happening, I don't know why?
BUT
When I run the same procedure without Declare it runs. see e.g. below:
Create Proc learn
@name varchar(20)
AS
Select @name
GO
It runs successfully. What is the difference between Declare and when I don't use Declare?

Try:
Create proc education
AS
Declare @name varchar(20)
Select @name='John'
Select @name
GO
exec education;
-- John
The first SELECT is only an assignment statement. You can use SET as well.
Create proc education1
AS
Declare @name varchar(20)
SET @name='John'
Select @name
GO
exec education1;
-- John
In the parameterized sp, the @name is set when the sp is called (exec).

Can we query a stored procedure results as an SQL Table ?

Hi,
Can we query a results from the results of a stored procedure returning a result set either as cursors or as PL/SQL Table like what we do like this
select * from <tablename>
select * from (select * from tablename) alias. instead of this, can we do like this
select * from (results of stored procedure) alias.
Please Provide any Help.

I agree. Pipelined Table Functions are the way to go.

MySQL 5.1 Stored Procs and Views not showing, only tables.

Hi,
I'm having problems getting stored procedures and views to show up in the Data Source Explorer of CR4E 2.0.
I've checked the properties of the connection and the Default Stored Procedure Filter is disabled, so things should show Tables are showing. The user within MySQL that I am using to connect also has rights to view sps and views.
My question is, has any one got views or sps to show within the Data Source Explorer using MySQL 5.1? Am I missing a trick here? Do I need to add anything to the url string of the mysql jdbc driver for the sps and view schemas to show.
Many thanks,
Nick

Hi,
As a work around you can use the CR2008 to design your reports based on stored procedures and then import the reports in Crystal Report For Eclipse IDE. You will be able to view the fields/Data coming from the Stored Procedures.
Thanks,
Neeraj
