Do You Replicate Views, Stored Procedures, And User Functions?
Jul 22, 2007
Greetings,
We have recently begun using transactional replication to keep the data in our SQL Servers synchronized in a geographically dispersed environment. We replicate our tables but we have never replicated views, stored procedures, or user functions in our production systems. We are thinking of doing so but wonder if the overhead of running the replication agents doesn't outweigh the benefits of having replication assist with the occassional change to these design elements.
Is anyone on this forum replicating views, sprocs, and user functions? What has your experience been?
Thanks for any ideas that you share.

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.

Hi,Right, i have a fairly good understanding of SQL. However, i have a fairly basic understanding of SQL Server.I know Storedprocedures are really good and i'm starting to use them. I understand they are good for making inserting, updating very easy.However when you look at a SQL Server database you get various folder, this leaves me a little confused with what they are all used for? whats the difference between these?Thanks in advance!sorry for the basic question, i'll try to challange you next time

Hi Folks,
I am writing a program that transforms a generic MS SQL database to make it compatible with our application. In order to make the transformation, I have to access all the elements of the generic database programmatically.
I know that the Master database contains all this information. Is there a query that allows me to access the "non-system" tables, sps, views, and functions?
For Tables, I need to know the Name(s) of the tables, the column names, the column type, ALLOW Nulls, Primary Key, Identity Seed settings, and Triggers.
For SPs, I need to know the Name(s) and access the SP source code (assuming it's unencrypted).
For Views, I need to know the Name(s) and access the Views Source
For functions, I need to know the Name(s) and access the function source.
I can see various tables in the Master database from management studio, like sys.objects, sys.tables - which look like they have the info I need. However, when I run a query against master like:
select * from sys.objects .. I get an error:
Msg 208, Level 16, State 1, Line 1
Invalid object name 'sys.objects'.
Thank you in advance.

Hi There,
I've written an inline table-valued function in SQL such as the following:
ALTER FUNCTION dbo.GetCityByID( @CityID int)
RETURNS TABLE
AS
RETURN(
SELECT
Name,
Url
FROM Cities
WHERE (CityID = @CityID) )
suppose that Cities table includes three fields (CityID, Name, Url).
By the way I wrote a store procedure as follow:
ALTER PROCEDURE MyProcedure ( @MyID int)
AS
SELECT
CountryID,
OriginCityID,
DestCityID
FROM
MyTable
WHERE (MyID = @MyID)
The OriginCityID and DestCityID are related to CityID in Cities table. I wanna get the name
and url of each city by its ID through this stored procedue by making relation to Cities table.
so I call GetCityByID function in my stored procedure like this:
ALTER PROCEDURE MyProcedure ( @MyID int)
AS
SELECT
CountryID,
dbo.GetCityByID(OriginCityID),
dbo.GetCityByID(DestCityID)
FROM
MyTable
WHERE (MyID = @MyID)
this procedure dosn't work an returns error.
What's your solution for getting information from Cities table for OriginCityID and DestCityID?
Thank you in advance.

Hello all:
Running into a brain problem here. I remeber reading an article a while back (2002?) on either Visual Studio Magazine or MSDN Magazine where there was a way to generate Stored Procedures from User Defined Functions. I need this information in order to do my job as it is also a way to cut down on time for this project I am trying to finish. Does anyone have the code or remeber what I am talking about. I just finished Kathleen Dollards article again on using XSLT to generate code but would really like to use the User Defined Functions.
I searched for the article on line but came up dry. Searched through all my magazines but could not find the article. Any help would be greatly appreciated. Bit of topic I guess but still relevant to the board.
Thanks

What are the pros and cons of each?
One advantage that I can see withh UDFs is that they are a bit a Views with parameters. You can perform joins on UDF columns (which you cannot do with a Stored Proc). You can do the same with Views but UDFs have the advantage that you restrict the number of rows with a parameterised WHERE (or HAVING) clause.

Hi to all, Can any body tell me what is the difference between Stored procedures and User Defined Functions ? In my assumption Function return a value or table, but SP doesn't return value instead of that SP use select statement or assign value to output statement. This is right?

Hi all.
The company I work for has several developers and each has his own database. They are all identical....each developer has his own so that he/she can work with data and not bother the other developers.
However, if one developer is assigned a category like billing and that person creates/modifies a stored procedure then that person needs to replicate those changes to all databases so everyone is in sync.
Granted, two people will never work on a category at the same time (at least not yet).
Right now, we have a script that does a good job copying the alter proc to all databases...works really well.
So my question is, how do you guys handle a similar situation? Anything better/worse?
Thanks!

Hi allTrying to figure out what you use ms sql functions for. I understand stored procedures and how to create them. the question is what is the real purpose of a ms sql function considering everything i have read so far makes me think that there is no valid use for them. You can do almost everything that a function does but in a stored procedure. If somebody can give me a good examplle of a sql function i would appreciate it very much.thanks

I hope I didnt POST in the wrong group. If I did sorry. Anyhoo, on to my question. I have searched the forums and didnt quite find what I was looking for so here goes..
I have create a function that is supposed to return the "SCOPE_IDENTITY" from a stored procedure that updates the database. I'm kinda lost as to how to get the SCOPE_IDENTITY into the function.
I have the following line in the function:
Dim retcode As Integer = cmd.Parameters.Add("@retcode", SqlDbType.Int).Direction = ParameterDirection.ReturnValue
...
cmd.ExecuteReader(CommandBehavior.CloseConnection)
and the following in the stored procedure
@retcode int=NULL OUTPUT
....
SELECT @retcode =SCOPE_IDENTITY()
RETURN @retcode
If I run the stored procedure by itself I get
@retcode = 135
@RETURN_VALUE = 135
So i know the stored procedure works but how do I get that return value into a asp.net function?

I have the following case.
I have a linked server and I want to execute SQL statements on that linked server which contains millions of records. so I decided to use SELECT * from OPENQUERY(RmtSrv,'SELECT * FROM RmtTbl WHERE Col = ' + @ColValue) but Unforetunatly the query is not succeeded because the OpenQuery doesn't accept parameters.
I used Scalar valued functions and built the query dynamically, but the Scalar valued functions doesn't execute dynamic SQL
ET @LinkedServerName = 'RmtSrv'
SET @RemoteTable= 'RmtTbl'
SET @Query = 'SELECT * FROM OPENQUERY({0}, ''SELECT Col1 FROM {1} WHERE Col2 = ''''{2}'''''') '
SET @Query = REPLACE(@Query, '{0}', @LinkedServerName)
SET @Query = REPLACE(@Query, '{1}', @RemoteTable)
SET @Query = REPLACE(@Query, '{2}', @Col2Value)
EXEC(@Query)
the above code is not executed because the functions doesn't execute dynamic queries.
I deleted the function above and wrote a Stored Procedure with the same code. but I can't query the stored procedure
SELECT GetColValue(Table1.Col1)
FROM Table1.
where the GetColValue is the name of the stored procedure.
Do you have any solution that I can use to perform Remote SQL statements considering the performancewise and the code shall be centralized in certain stored procedures and functions
the Remote server contains millions of records and I will use it from tens of applications and databases.

Hi all,
In one of my UDF I use the following functions:
.....
and len(@int_date) = 4
and isnumeric(substring(@int_date,5,6)) = 1
when I use the function I get
Only functions and extended stored procedures can be executed from within a function.
Yes, when I comment the two lines the function works fine.
Ehm.... why can't I use these functions in my function ?
Thanks: Peter

WE release our software once a week. In 1 months time we will have over 500 stored procedures in our DataBase.
What we do for releases is when a stored procedure is changed, we put the Drop and Create parts of that script in our SQL Update Script.
A problem comes up when Developer A changes My_StoredProc and then developer B changes the same stored procedure. Sometimes it works ok (the developer B will run the update script before changing his stored procedure. HOwever, it can happen where one Update script file has the same SP 5 times (5 drops 5 creates)... especially if over 300 SP's are getting updating in 1 release.
We will always catch these on our tests, however, it's the 2 hours to fix the Test DB after we run these tests...
What is the best way to manage these? We thought about putting our stored procedures into Team Foundation Server, but we don't know if that will work for us.
We have 8 developers in our team.
If anyone could help or give advice on this, it would be awesome.
Thanks.

Hi, l've created an function [GSM].[KPIAging], and test it in studio by substitule declare value, i.e.
DECLARE @sCellName VARCHAR(8)

SET @sCellName = "CELL1M_1"
SET @dDate = CAST('06/Jun/2006' AS DATETIME)
EXEC GSM.KPIAging @sCellName, 'CSSR', @dDate
It work fine and return the desired result, but when l used this function in SQL,
SELECT DATEKEY, CELLREGIONKEY, CELL_NAME, CELL_ID, CSSR, GSM.KPIAging(Cell_Name, 'CSSR', @dDate)
FROM GSM.GSMCellDaily_vw
WHERE CSSR BETWEEN 0 AND 85
AND FULLDATE = @dDate
AND CM_SERV > 30
AND (TCH_TRAFFIC > 2 AND TCH_SEIZURES_ATTS > 30)
I got the following error, i.e.
Msg 557, Level 16, State 2, Line 19Only functions and extended stored procedures can be executed from within a function.
Does anyone have any idea on this, and what's the workaround for this?

I am a bit confused by the difference between a stored procedure and a table-valued function. Can somebody please either give me a simple explanation, or point me at something I can read.
I thought I had it worked out, and had coded some action queries as stored procedures, and I wrote a table-valued function that was effectively an encapsulated SELECT so that SELECT * FROM Spouse(@ID) worked fine. Then I wanted to use a function SpousePair, that was similar to Spouse, to power a Gridview. I discovered that I couldn't. It seems that a SQLDataSource requires either a SELECT statement or a stored procedure. So I wrote a stored procedure SpousePair(@ID1, @ID2).
I find that whereas I tested Spouse with
SELECT * FROM SPOUSE(@ID)
I tested SpousePair with
EXEC SpousePair @ID1 @id2
Now I want to combine these: if I could I would write
SELECT * FROM SPOUSE(@ID) WHERE SPOUSEID NOT IN
(SELECT SPOUSEID FROM SpousePair(@ID1, @ID2))
However this is invalid because you can't put a stored procedure in a Select statement, and SELECT .... NOT IN (EXEC SpousePair @ID1 @ID2) is also invalid.
Is there any alternative to creating a table-valued function, SpousePairA, that is identical to SpousePair but coded as a function. I'm reluctant to do this because then I'll have two bits of quite complicated SQL logic to maintain.

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.
Thanks for any help.
