Best Practice For View Or Stored Procedure
Oct 31, 2007
I have a view setup on db2 that I am accessing from our sql server. I'm trying to figure out how I could setup a view or stored procedure on the sql server to access the db2 view so the developers don't have to use the openquery statement, but still could query it like they had access to a table. In other words, I want them to be able to specify whatever columns they need to from the sql server stored procedure or view without sacrificing performance on the db2 side of things. I don't want to select every record from the db2 view or stored procedure and then filter based on that criteria.
I think I need to use a stored procedure to accomplish what I am trying to do. I would also like to prevent any type of sql injection attacks. Therefore, I didn't want to just create a long varchar variable and store the entire where clause in the varchar variable. In addition, I want the developers to be able to specify only the columns needed to be returned.
select * from openquery ([linkedServer], 'select * from catalog.schema.table where column1=''A''')
select * from openquery ([linkedServer], 'select column4 from catalog.schema.table where column1=''A'' or column2=''A'' or column3=''A''')
Any help would be greatly appreciated.

Hi all,
I have this stored procedure which works fine but I am unsure if I should be doing anything different to improve the overall efficiency of it or any other things that may need changing to shorten the code etc.
It takes in some parameters from an ASP page and puts them through some conditional statements.
Here it is:
CREATE PROCEDURE [imagineDB].[sp_treatment]
-- parameters
@id int = 0,
@ikeyword int = 0,
@keyword nvarchar(100) = NULL
AS
if @id <> 0 OR @ikeyword = 1
if @id <> 0 and @ikeyword = 0
begin
SET NOCOUNT ON;
SELECT id, pageTitle, description FROM ihcProcedures where id = @id order by pageTitle ASC
end
if @id = 0 and @ikeyword = 1
begin
SET NOCOUNT ON;
SELECT id, pageTitle, description FROM ihcProcedures where description like '%' + @keyword + '%' order by pageTitle ASC
end
if @id <> 0 and @ikeyword = 1
begin
SET NOCOUNT ON;
SELECT id, pageTitle, description FROM ihcProcedures where id = @id and description like '%' + @keyword + '%' order by pageTitle ASC
end
else
if @id = 0 and @ikeyword = 0
begin
SET NOCOUNT ON;
SELECT id, pageTitle, description FROM ihcProcedures order by pageTitle ASC
end
else
if @id = 0 and @ikeyword = 1
begin
SET NOCOUNT ON;
SELECT id, pageTitle, description FROM ihcProcedures where description like '%' + @keyword + '%' order by pageTitle ASC
end
thanks in advance

Not sure what the best forum on this site for this. Looked around but couldn't find.
When I google this... I just get a million threads about how to call stored procedures in c#.
But what I want to do in this case is call a C#.net app from a stored procedure. It will need to be backwards compatible for 2000 unfortunately. I could compile the C# app as a win-32 app and kick it off from the Stored Procedure with command line parameters. But is there a better way? What is best practice?

I've recently inhereted an environment in which we have over 600 storedprocedures. The documentation is either very poor or non-existant andam needing advice on how to determine if a stored procedure has beenused. Does SQL Server have any sort of ticker that indicates when astored procedure was last used?Thanks and any additional information or experience would be greatlyappreciated.

I would like to have a stored procedure executed once a week via a DTS package. The data I would like inserted into Table_2, which is the table where the DTS is being executed on, comes from a weekly dump from Oracle into a Table_1 via another DTS package.
I would like to only import data since the last import so I was thinking of my logic to be like this:
INSERT INTO Table_2
(Field1, Field2, ... , FieldN)
VALUES (SELECT Field1, Field2, ... , FieldN FROM Table_1 WHERE ThisDate > MAX(Table_2.ThatDate))
Does this make sense? Or do you all suggest a different mannger of accomplishing this?

Hi guys 'n gals,
I created a query, which makes use of a temp table, and I need the results to be displayed in a View. Unfortunately, Views do not support temp tables, as far as I know, so I put my code in a stored procedure, with the hope I could call it from a View....
I tried:
CREATE VIEW [qryMyView]
AS
EXEC pr_MyProc
and unfortunately, it does not let this run.
Anybody able to help me out please?
Cheers!

I'm modifying a pretty big web application and the programmer who built it used all stored procedures and no views. Does anyone know why someone would do this? I realize that you can't pass parameters with views and insert/update/delete records with views, but he even used stored procedures for queries like: SELECT * FROM myTable WHERE myVal > 0 ORDER BY myVal Is it more efficient to put this in a stored procedure compared a view?

Hello all I am not quite a beginner but not an expert at SQL. I'm kind of in a bind and need some help. I have a table that shows me statuses of tickets (open, pending, closed), some tickets could have as much as 25 rows/ticket. I want to try to avoid that but at the same time keep track of the time. Here's what I need to happen...
with the data example below I need to take the ((closed date - first open date) - total of Waiting time). This will give me total time duration of the ticket. I'd like to either write a stored procedure or create a view that would do this for me. Any one have ideas?

Hi all,
I want to know if there is a way to use a stored procedure in a view OR
a table value function OR
use the store procedure in table value function.
If any of these is a possibility, it would help. So far i have learnt that extended stored procedures can be accessed in table value functions.

Hi i have a page in which a user fills out info on a page, the problem i am getting is that when the save button is clicked all text box values apart from one are saving to the database this field is the "constructor_ID" field.

Is it possible to drop and then create a view from a stored procedure? Like the way you can drop and create a temp table.
I want to create a view of the fields in a table something like: But I cannot include the field names, they may be changed by an admin user.
If exists view 'custom_fields"
drop view 'custom_fields'
Create view custom_fields
Select * From tblCustomFields
And make this a view in the db named custom_fields.
And I want to call it from a button click in my UI.

hi,
Can someone tell me when to use SQL Server View as oppose to Stored Porcedure?
Currently we do everything with SQL Server stored procedure. I mean, even if we have to display some report, we use Stored Procedure.
In what situations and senarios views are better and one should consider them over Stored Procedure?

Hi
I need to create a view using a stored procedure .
The task is to Upload multiple sql server tables sourcing data from flat files as well as SQL server tables .It is the process of Data migration.
After loading few tables,I need to create a view on thoes tables which can be used (queried )to load furthe tables.
I need to AUTOMATE THIS PROCESS .Means Once I schedule the job .It should take fire the stored procedures one after another .
I am thinking to create a view though a stored procedure .
You can suggest me alternate ways to do same .

Joe, thank you for the answer to my post.
Can I also use a
SELECT field1 FROM DBName.dbo.TableName with a "VIEW" in this other database (that's on the same server)?
Also, in my sp, I have the following:
SELECT DISTINCT Store.[DemoID#], Progstats.ProgramName, Progstats.[Program#], ZCHAIN.STR_NAME, ZCHAIN.[STR#], ZCHAIN.ADDRESS,
ZCHAIN.City, ZCHAIN.ST, ZCHAIN.ZIP, ZCHAIN.[PHONE#], Store.D1, Store.Status, Store.AgencyCompleted,
Store.Reason, Store.LeadName, Store.DemonstratorName, Store.UpdatedOnline
FROM (Store INNER JOIN Progstats ON Store.[Program#] = Progstats.[Program#]) INNER JOIN ZCHAIN ON Store.[TD#] = ZCHAIN.[ID#]
WHERE (((Store.[DemoID#])=@DemoID)) AND Progstats.Status=1;
GO
ZCHAIN has now become this "VIEWZCHAIN" in this other database. So, could I simply relace "ZCHAIN" with "DB2.dbo.VIEWZCHAIN.STR_NAME" which is actually now a 4-part name?
Thanks,
John Wilson

Hiya folks,
I'n need to access a view from within a SProc, to see if the view returns a recordset and if it does assign one the of the fields that the view returns into a variable.
The syntax I'm using is as follows :
SELECT TOP 1 @MyJobN = IJobN FROM MyView
I keep getting an object unknown error (MyView). I've also tried calling it with the 'owner' tags.
SELECT TOP 1 @MyJobN = IJobN FROM LimsLive.dbo.MyView
But alas to no avail!
Any offers kind people??

hi,
Im am wandering if it is possible to create two views in two different tables from within the same stored proc:ex
create proc myProc
as
use [myDb1]
go
create view myV1
as
select * from mytable
go
use [myDb2]
go
create view myV2
as
select * from mytable
go
go
---
of course the go's are not allowed in a sproc, the create statement must be the first of a query batch and a vew can not have the databaase name preapended like when creating a table plus one can not use the "use" word in a proc, I tried using exec to bypass the "first statement in a batch" and go restrictions but have not been able to overcome the "use [myDb]" restriction, is there a way to solve this problem?
thank you
