Hello all,
I'm looking for a best practice.
Let's say you have a report that contains out of 3 queries.
How are you going to create the report and why?
1. Just use "select * from table where p1= value" in your report
2. Save the query in your db as a view and use the view in your report
3. Create a procedure that contains all 3 queries. And use the procedure with some parameters in your report?

Hi, all experts here,
Thank you very much for your kind attention.
I am having some questions on indexed views and aggregate tables.
My question is: To improve the performance of the queries, is it better to use indexted views or aggregates tables for those aggregates which are often queried?
I am looking forward to hearing from you.
Thank you very much in advance for your help.
With best regards,
Yours sincerely,
All -
I am using SQL Server 2005 and I have an endpoint that exposes some stored procedures as web-methods in the endpoint.
One particular stored procedure I have exposed takes a long time to execute: about 10 - 15 minutes. While, it is OK, that this stored procedure takes this long, it is not desirable for the HTTP Request that executed this proc to not wait for that long.
What I want to be able to do is to call the stored procedure and have the call return immidetaly but the stored proc continues what its doing. I will call another stored proc at a later time to retrive the result of the first stored proc. The first proc will store its results in a temp table. I am thinking of using SQL Server Service Broker to achieve this.
Is there a better a way to achieve this? And how does SQL Server process the Service Broker requests, i.e., I dont want the query to be executed when the server is busy. Are there any hints that I need to give to Service Broker to be able to do this?
Thanks.
Hi,
I have 3 tables: authors, companies, and countries.
I have a stored procedure defined as:
PROC addAuthor(AuthorName, CompanyID, CountryID)
INSERT INTO authors (author_name, comp_id, country_id) VALUES( authorName, CompanyID, CountryID)
END PROC
....So the ID of the company and the country are the parameters. This makes it easy since I can just do a direct INSERT statement into the authors table.
Would it be better practice if the parameters asked for the name (not the ID's) of the company and country instead? This way we do not have to memorize the ID's for everything. So for example
PROC addAuthor(AuthorName, CompanyName, CountryName)
SELECT COUNT(*) FROM companies INTO v_numRows WHERE companies.company_name = CompanyName
IF v_numRows = 0
-- error
END IF
SELECT COUNT(*) FROM countries INTO v_numRows WHERE countries.country_name = CountryName
IF v_numRows = 0
-- error
END IF
END PROC
yeah, I might have the SQL syntax wrong up there (not entirely sure how it works for variables) but the gist of it is that I will need to include validation code within the stored procedure.
What do you guys think of this? Which method do you prefer? Is there a significant performance decrease with using the second method?
Thanks for any insights
I have a Product Table.
And now I have to create its Stored Procedures.
I am asking the best practice regarding the methods Insert And Update.
There are two options.
1. Create separate 2 procedures like InsertProduct and UpdateProduct.
2. Create just 1 procedure like ModifyProduct. In which programmatically check that either the record is present or not. If present then update and if not then insert. Just like Imar has done in his article http://imar.spaanjaars.com/QuickDocId.aspx?quickdoc=419
Can any one explain the better one.
Waiting for helpful replies.

Hello:I am new to T-SQL programing, and relativly new to SQL statements ingeneral, although I have a good understanding of database theory. I'm alittle confused as to the fundamental differences between a view and aquery, or rather, when it is more appropriate to use one vs. the other.It seems to me that most select queries can be implemented as views, and Ican't see the downside to doing so.I have a rather complicated database structure in terms of the relationshipsbetween various tables, and to get the information that I need into the userinterface forms I have to use a number of nested queries (first to combinetables together that have been normalized to place the related info in asingle table, then next to extract only the info that I require. In somecases I would need a 3 level deep nested query to get to what I need. Byimplementing the first step, that of combing the normalized tables back intoa single table as a view, it seems to me that I've completed the first stepat the database level, thus making my queries or stored procedures easier toimplement.I would appreciate any comments which can help me to decide when it is or isnot appropriate to use a view in these circumstances. I should point outthat I don't plan on using the views as part of action queries since theyare made up of multiple tables, I'm primarily interested in using them tooutput data which has been consiolidated from multiple tables.Thanks in advance to any and all who take the time to reply.

Hello,
I have a question where the answer may be simply opinion, or there may be strong reasons. I guess that's why I'm asking the question...
The question is - when should one create a view, and when should one use a stored procedure? Obviously, when doing multiple queries or passing parameters, you must use a SP. I'm talking about the case of a single query perhaps joins a couple of tables.
Hope that's not a stupid question...
Thanks in advance,
Paul
Good evening:Can anyone give me the low-down on using view from within my stored procedures? I've got some rather complex views that join multiple tables resulting in a staggering SQL query. I then use stored procedures to accept input parameters to determine order by and direction clauses. This results in some rather large "IF ELSE IF ELSE IF..." statements in my SP. Put a complicated SQL query together with lots of IF THEN and it becomes difficult to keep stuff straight in the SP. Therefore, using the view to keep my SQL in one place is an ideal solution. However, and here's the question, does it have a negative impact on speed and/or scalability. We plan to use these SP's within an ASP.NET website that may get a very large amount of traffic. Any advice/help you can give me would be really appreciated. Thanks!

Hello,
This maybe a simple question, I'm using reporting services to make a report, question is can I write a stored procedure that queries from a join of two views instead of two tables?
I'm having trouble getting my table data into the reportable state I want it, and I think organising into views might be easier.

Hi All,
Novice question. Would someone explain tell me what a view is used for? Also I am confused about the difference between a function and a stored procedure. They both seem like functions to me.
Please could someone explain to me the differences between a storedprocedure and a view.The reason for this question is I have two almost identical ASP pages.Both get the same results but one uses a stored procedure and one usesa view. If the query returns no results the 'view page' generateserrors and therefore I have to check for BOF and EOF, whereas the'stored procedure page' does not generate errors and instead wouldappear to return a recordset with 0 entries.Thanks in advanceNeil.

Hi
what is the diffrence between views and stored procedures in sqlserver 2005
thanks in advance.
Can you create views within a stored procedure?
Can Microsoft Access access a stored procedure on the SQL Server? If not, is there any way to assign a parameter to a view? I can link to a view in Access, but I cannot link to a procedure. I need to SELECT * from aTable WHERE ID = [@PassidInID]. Any way to do this through Access? The reason for this, is because I am trying to run an existing query (which is very busy - using other queries with queries in them etc.), and I keep getting an ODBC error. I am thinking that if I move the queries to the SQL Server, it may get rid of this error?
It's a 2-tier app I have. Tables on the server, forms, queries, and everything else in Access.
Thanks in advance - I hope.
Hello Everybody,
I posted this same question couple of times in the news groups but no answers. I have a 2 tables and i am doing a union query using a view. each has 250 rows. The query takes 20 seconds to return the results. no joins or anything. the create view simply looks like this:
create view myview as
select id, name from table1
union
select id,name from table2
Where as if i write a stored procedure like below, it returns the rows in 4 seconds.
create table #mytable
( id int, name varchar(30))
insert into #mytable (id, name) select id, name from table1
insert into #mytable (id, name) select id, name from table2
select id,name from #mytable.
I prefer doing in the view since both returns the same result. I tried running dbcc, update statistics. but no luck. Can anyone please help me in this issue.
Thanks

Hi
What permissions do I need to set so that a user can change tables, views and procedures?
I have a multiple table dataset that needs to be returned, with at least 5 joins, some inner, some left outer.
Currently, this is done via a parameterized stored prodedure, which is used fairly frequently. The parameters only affect the where clause, not the joins.
Would it be better to create the view with the joins already done, then pass in the parameters with the stored procedure? Which is better for overall performance? Which is better for quicker response times to the calling asp.net application?
Thanks in advance,
Leah
This is a general question regarding the use of view and storedprocedures. I'm fairly new to databases and SQL.I've created a SQL database using an Access Data Project ("ADP") andI'm satified with the table structure. I've moved on to building somefront ends for our users.I'm running into situations where I want subreports to be built fromqueries [views or stored procedures-I don't know which to use so I usethe term query] that are dependent on the values in other controls.I've played with stored procedures and I've figured out how to sendcriteria to a stored procedure and then dynamically change the recordsource of a subreport.However, I'm running into cases where I can't add records to theresults of a stored procedure. The table I'm running a stored procedureon has five fields: (1) Primary Key for each record, (2) FundID that'sa primary key in another table, (3) CompanyID that's a primary key inanother table, (4) Attribute 1 of the (Fund/Company) and (5) Attribute2 of the (Fund/Company).The stored procedure filters the set of Fund/Companies based on aFundID from a form. I can update this stored procedure. However, forusers, they would like to see the Fund Name from the table that hasunique FundIDs. As soon as I include that into the stored procedure, Ican no longer add records.My questions are many:1. Is there a primer online that discusses the theory behind myquestion? Recordsets, updatability, working with recordsets in forms?2. What are some best practices for developing subreports, combo boxes,list boxes, etc. where the data is dependent on the values in a control3. I'm struggling with the best ways to grab objects on a form. If I'mon the main form I'm comfortable working with theMe.__object__.__sub-oject routine. However, if I'm in one subform whereI need another subform to change based on the record I'm in, I feelthat my code to get at the subform is very klunky..forms.main form name.sub form name.form.record sourceI don't even know how I figured out the "form" part before recordsource. Again, are there some basic rules or guides about navigatingthrough forms in VBA?4. Should I be developing front ends in some other environment?I know it's a lot, but all the advice from the newsgroups seems topresuppose some knowledge about how ADP, ADO, ODBC..blah blah and Ican't seem to find any documents about ADP and SQL.

Hi,
I would like to use the view of the company data in the following stored procedures
without needing to pass a value into the CompanyID identity column. Is there a way to do this? The following code contains the view, the insert trigger on the view, and the desired stored procedures.
Also, this code is given me problem as well the error message says it cannot convert varchar to int. This code is located in the insert trigger.
INSERT INTO State(StateName)
VALUES(@StateName)
Here is the code of the company view, notice the C.CompanyID it is used in the GetCompany stored procedure.
SELECT C.CompanyID, C.CompanyName, A.Street, A.City, S.StateName, A.ZipCode, A.Country, P.PhoneNumber
FROM Company AS C INNER JOIN
Address AS A ON C.AddressID = A.AddressID INNER JOIN
State AS S ON A.StateID = S.StateID INNER JOIN
Phone AS P ON C.PhoneID = P.PhoneID
Here is code for the insert trigger on the view
CREATE TRIGGER InsertTriggerOnCustomerView
ON ViewOfCompany
INSTEAD OF INSERT
AS
BEGIN
DECLARE @CompanyName VARCHAR(128)

Hi,
I have a quick question about pushing things onto the database to do. It is supposed to be more efficient, and it is more secure. The downside as far as I can tell is that one can end up with incredibly expensive and complex database deployment using costly servers and software.
Is there an approach that minimizes database query time by moving much of the processing to the (less efficient) web server calling the database, and then only using simply queries. One would then process the data in code, stripping it down to exactly what is needed, rather than doing complex things on the db itself.
An example of this might be that you want to parse a field on a particular char. and return only the first part of the string, up until this char occurs. This can be done on the db server, but...
I understand that one might return extra information, but it seems there is a large potential payoff in less complexity and expense.
Anyway, if you know of such an approach and the name of it, I would appreciate hearing it,
Thanks
