Stored Procedures -- Correct Practice?

Jan 16, 2008

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

Determine Correct Flow Of Stored Procedures

Mar 12, 2015

We have some pre-defined stored procedures(around 4-5) which deletes/ truncates the tables.

- Is there a way I can know the correct order of running the SP.May be I should check that child tables are deleted first and then the parent tables.

- How can I test the same. Since I am not aware of the flow thereby should I try running with NO eligible records for deletion. Will this ensure that I have sufficient privileges for the SP or do I need to delete a record (may b an older record).

Sysdepends And Compiling Stored Procedures In The Correct Order

Nov 9, 2000

Hello:

We are presently testing various upgrade scripts to our current application which is scheduled to shortly be upgraded to mssql 7.0. We are testing under mssql 7.0,sp 2.

As it works now, I receive some existing scripts that have been modified and some stored proceures that are new. For the existing stored procedures, I usually take my best guess as to what the order of creation will be, test it in my script for recompile(actually all are dropped first and then the guesswork on the creates). This is usually trial and error as I run the script, see any sysdepends errors such as:

"CREATE PROCEDURE: ep_invoiceheaderformat_spv0101
Cannot add rows to sysdepends for the current stored procedure because it depends on the missing object 'ep_assumepay"

And then move the order of the create procedures around in the script and try again until I get a clean run in a test database I use just to syntactically test the scripts.

I looked at the sysdepends table for the database and pretty much decided that the object numbers and stuff was pretty much incomprehensible to me.


Alternatively I could compile each one separately but I would have the same problem subsequently trying to generate a script of the al of the create procedures... in the right order which would not

My question is:

1) Is there a way I can read and understand what the data means in sysdepends?

2) Figure out a way to utilize the data there to create or generate the create stored procedure text in the correct clean compile order?

3) Any other suggestions?

Any information which can be proveded will be greatly appreciated. Thanks.

How Can I Execute Stored Procedures With Correct User Rights?

Sep 3, 2007

Hi,

I have a problem with sp execution.:







objects of [dbo]

Tables of [nuran]

Grants of [nuran]


[dbo].tabloA

[nuran].tmptabloA

Select,insert, update on [dbo].tabloA


[dbo].tmptabloA



Deny for [dbo].tmptabloA


[dbo].sp_yordam



Grant for executing [dbo].sp_yordam









(1)
create PROCEDURE [dbo].[SP_yordam]
AS
BEGIN

BEGIN TRANSACTION @Tran1
€¦€¦€¦€¦€¦. €¦€¦€¦€¦€¦€¦ €¦€¦€¦€¦.

INSERT INTO [tabloA]
(, ,)
SELECT ,,
FROM [tmptabloA] WHERE ......

€¦€¦€¦ €¦€¦€¦ €¦€¦€¦.

DELETE FROM [tmptabloA]

COMMIT TRANSACTION @Tran1


When user [nuran] execute the procedure sp_yordam by a VB program, the procedure use [dbo].tmptabloA not [nuran].[tmptaboA]. If there are data in the [dbo].tmptabloA, the procedure insert data to [dbo].tabloA from [dbo].tmptabloA. But when I checked user name in the procedure during execution, the user was [nuran].

If I write the procedure like that:

(2)
create PROCEDURE [dbo].[SP_tmpSil]
AS

declare @tablo1 as varchar(50),
DECLARE @sil as nvarchar(max)
select @tablo1='[tmptabloA]'

SELECT @sil = ' DELETE FROM ' + @tablo1 + ';'
EXEC (@sil)

END

And it executed by user [nuran],then it used the correct table [nuran].tmptabloA

Is there any way to use user€™s table in an stored procedure without using the user name :
(3)
create PROCEDURE [dbo].[SP_yordam]
AS
BEGIN

BEGIN TRANSACTION @Tran1
€¦€¦€¦€¦€¦. €¦€¦€¦€¦€¦€¦ €¦€¦€¦€¦.

INSERT INTO [tabloA]
(, ,)
SELECT ,,
FROM [nuran].[tmptabloA] WHERE ......

€¦€¦€¦ €¦€¦€¦ €¦€¦€¦.

DELETE FROM [nuran].[tmptabloA]

COMMIT TRANSACTION @Tran1


I don't want to use (2) and (3) code methods, I prefer to use (1) script. Is there any compilation method, or any aditional way for using script (1) with correct user rights?

Thanks a lot

Queries, Views, Procedures : Best Practice

Nov 23, 2007

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?

Best Practice: Procedures: (Insert And Update) OR JUST (Save)

Aug 18, 2007

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.

Correct Procedures For Testing Against NULLs From SQL Server

Jul 7, 2005

Hi all,

I have some C# code that is pulling data from a database where a majority of the values being retrieved are NULL , yet their initial column data types are both string and int, which means that I have to temporarily store these NULL's in int and string data
types in C#. Later on in my code I have to test against these values,
and was wondering if I am doing it correctly with the following code.

The following statement the variable or_team_home_id is of a string data type, but may have had a NULL value assigned to it from the database
if (!or_team_home_id.Equals(DBNull.Value)) {}

The following statement the variable or_manager_id is of a int data type, but also may have a NULL value assigned to it from the database.
if (!Convert.IsDBNull(or_manager_id)){}

Are these the correct way to test against NULL values retrieved from
teh database and that are stored in their respective data types.

Stored Procedure Best Practice

Jun 24, 2008

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

Best Practice - Calling C#.net App From SQL Stored Procedure

May 13, 2008

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?

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.

Stored Procedures 2005 Vs Stored Procedures 2000

Sep 30, 2006

Hi,



This Might be a really simple thing, however we have just installed SQL server 2005 on a new server, and are having difficulties with the set up of the Store Procedures. Every time we try to modify an existing stored procedure it attempts to save it as an SQL file, unlike in 2000 where it saved it as part of the database itself.



Thank you in advance for any help on this matter

Stored Procedure - SELECT INSERT Statement - Good Practice?

Jan 9, 2004

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?

Best Practice For A Long Running Queries / Asynchronously Calling A Stored Proc?

May 23, 2008

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.

All My Stored Procedures Are Getting Created As System Procedures!

Nov 6, 2007



Using SQL 2005, SP2. All of a sudden, whenever I create any stored procedures in the master database, they get created as system stored procedures. Doesn't matter what I name them, and what they do.

For example, even this simple little guy:

CREATE PROCEDURE BOB

AS

PRINT 'BOB'

GO

Gets created as a system stored procedure.

Any ideas what would cause that and/or how to fix it?

Thanks,

Correct Way To Insert Data Into Multiple Tables (Stored Procedure)

Nov 3, 2007



Hi

I am currently developing my first database driven application and I have stumbled over some quite simple issue. I'll describe my database design first:
I have one table named images(id (identity), name, description) and one table named albums (id, name, description). Since I'd like to establish a n:n connection between these, I defined an additional table ImageInAlbum (idImage, idAlbum). The relation between these tables works as expected (primary keys, foreign keys appear to be ok).

Now I'd like to insert data via a stored procedure in sql server 2005 and I'm not sure how this procedure will look like.
To add a simple image to a given album, I am trying to do the following:
* Retrieve name, description from the UI
* Insert a new row into images with this data
* Get the ID from the newly created row
* Insert a new row into "ImageInAlbum" with the ID just retrieved and a fixed Id from the current album.

I know how I would do the first two things, but I am not used to Stored Procedures syntax yet to know how to do the other things.

Any help is appreciated ... even if it means telling me that I am doing something terribly wrong

Using A Stored Procedure To Query Other Stored Procedures And Then Return The Results

Jun 13, 2007

Seems like I'm stealing all the threads here, : But I need to learn :) I have a StoredProcedure that needs to return values that other StoredProcedures return.Rather than have my DataAccess layer access the DB multiple times, I would like to call One stored Procedure, and have that stored procedure call the others to get the information I need. I think this way would be more efficient than accessing the DB  multiple times. One of my SP is:SELECT I.ItemDetailID, I.ItemDetailStatusID, I.ItemDetailTypeID, I.Archived,     I.Expired, I.ExpireDate, I.Deleted, S.Name AS 'StatusName', S.ItemDetailStatusID,    S.InProgress as 'StatusInProgress', S.Color AS 'StatusColor',T.[Name] AS 'TypeName',    T.Prefix, T.Name AS 'ItemDetailTypeName', T.ItemDetailTypeID    FROM [Item].ItemDetails I    INNER JOIN Item.ItemDetailStatus S ON I.ItemDetailStatusID = S.ItemDetailStatusID    INNER JOIN [Item].ItemDetailTypes T ON I.ItemDetailTypeID = T.ItemDetailTypeID However, I already have StoredProcedures that return the exact same data from the ItemDetailStatus table and ItemDetailTypes table.Would it be better to do it above, and have more code to change when a new column/field is added, or more checks, or do something like:(This is not propper SQL) SELECT I.ItemDetailID, I.ItemDetailStatusID, I.ItemDetailTypeID, I.Archived,     I.Expired, I.ExpireDate, I.Deleted, EXEC [Item].ItemDetailStatusInfo I.ItemDetailStatusID, EXEC [Item].ItemDetailTypeInfo I.ItemDetailTypeID    FROM [Item].ItemDetails IOr something like that... Any thoughts?

How To Save Stored Procedure To NON System Stored Procedures - Or My Database

Stored Procedure Being Saved In System Stored Procedures

Apr 7, 2006

We recently upgraded to SQL Server 2005. We had several stored procedures in the master database and, rather than completely rewriting a lot of code, we just recreated these stored procedures in the new master database.

For some reason, some of these stored procedures are getting stored as "System Stored Procedures" rather than just as "Stored Procedures". Queries to sys.Objects and sys.Procedures shows that these procs are being saved with the is_ms_shipped field set to 1, even though they obviously were not shipped with the product.

I can't update the sys.Objects or sys.Procedures views in 2005.

What effect will this flag (is_ms_shipped = 1) have on my stored procedures?

Can I move these out of "System Stored Procedures" and into "Stored Procedures"?

Thanks!

SSIS And Stored Procedures Results Stored In #Tables

Mar 26, 2008

Hello
I'm start to work with SSIS.

We have a lot (many hundreds) of old (SQL Server2000) procedures on SQL 2005.
Most of the Stored Procedures ends with the following commands:


SET @SQLSTRING = 'SELECT * INTO ' + @OutputTableName + ' FROM #RESULTTABLE'

EXEC @RETVAL = sp_executeSQL @SQLSTRING


How can I use SSIS to move the complete #RESULTTABLE to Excel or to a Flat File? (e.g. as a *.csv -File)

I found a way but I think i'ts only a workaround:

1. Write the #Resulttable to DB (changed Prozedure)
2. create data flow task (ole DB Source - Data Conversion - Excel Destination)

Does anyone know a better way to transfer the #RESULTTABLE to Excel or Flat file?

Thanks for an early Answer

Calling Stored Procedures From Another Stored Procedure

May 8, 2008

I am writing a set of store procedures (around 30), most of them require the same basic logic to get an ID, I was thinking to add this logic into an stored procedure.

The question is: Would calling an stored procedure from within an stored procedure affect performance? I mean, would it need to create a separate db connection? am I better off copying and pasting the logic into all the store procedures (in terms of performance)?

Thanks in advance

Calling A Stored Procedure Inside Another Stored Procedure (or Nested Stored Procedures)

Nov 1, 2007

Hi all - I'm trying to optimized my stored procedures to be a bit easier to maintain, and am sure this is possible, not am very unclear on the syntax to doing this correctly.  For example, I have a simple stored procedure that takes a string as a parameter, and returns its resolved index that corresponds to a record in my database. ie
exec dbo.DeriveStatusID 'Created'
returns an int value as 1
(performed by "SELECT statusID FROM statusList WHERE statusName= 'Created') 
but I also have a second stored procedure that needs to make reference to this procedure first, in order to resolve an id - ie:
exec dbo.AddProduct_Insert 'widget1'
which currently performs:SET @statusID = (SELECT statusID FROM statusList WHERE statusName='Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
I want to simply the insert to perform (in one sproc):
SET @statusID = EXEC deriveStatusID ('Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
This works fine if I call this stored procedure in code first, then pass it to the second stored procedure, but NOT if it is reference in the second stored procedure directly (I end up with an empty value for @statusID in this example).
My actual "Insert" stored procedures are far more complicated, but I am working towards lightening the business logic in my application ( it shouldn't have to pre-vet the data prior to executing a valid insert). 
Hopefully this makes some sense - it doesn't seem right to me that this is impossible, and am fairly sure I'm just missing some simple syntax - can anyone assist?
