Hi, all here, I am having a question about stored procedures for data mining. What are the main benefits of stored procedures for data mining? (what stored procedures can do for data mining on sql server 2005? when they are useful for data mining?).
Could please any expert here give me any guidance for that? Thanks a lot in advance.
With best regards,
Yours sincerely,
I want to know the differences between SQL Server 2000 storedprocedures and oracle stored procedures? Do they have differentsyntax? The concept should be the same that the stored proceduresexecute in the database server with better performance?Please advise good references for Oracle stored procedures also.thanks!!

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
Hi !
We're designing our data model, and have found that we have two groups of tables (about 10 tables in each group). The tables within each group are dependent, but the two groups are independent of eachother.
Now, our two choices are:
1. Put all tables into one database.
2. Put the two groups into two separate databases.
For simplicity, option 1 is the winner. However, my question is, will there be noticeable peformance benefits by using two databases? (In which case, option 2 will be the winner).
Thanks,
Martin
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,

Just curious. The exec plan is the same for both qry's, and they both show the same estimated row counts @ the point of question in the exec plan. The exec times are roughly the same, any variances I'm attributing to db load from other things going on, since any benefits of one over the other are not consistent from execution to execution. So is there any benefit to filtering in the join conditions vs. the where clause? My thinking was that by filtering earlier in the qry (when joining) as opposed to "waiting" to do it in the where clause, the rest of the qry after the join would inherently be dealing w/a smaller result set for the rest of it's execution, thus improving performance. After the exec plan checking I did, I guess I was wrong. Seems that Sql Server is intelligent about such filtering when analyzing the entire qry, and building its execution accordingly. The execution plan for both qry's showed the same where clause argument for the tables being joined.
Filtering in where clause....
Code:
select...
FromtProject p with (noLock)
jointProjectCall pc with (noLock) on P.ID = pc.project_id
jointStore S with (noLock) on pc.store_id = s.id
jointZip Z with (noLock) on Z.zip5 = s.zip5
jointManager M on M.ID = case ... end
leftjoin
(
selectprojectCall_RecNum as RecNum, sum(answer) as HoursUsed
fromtCall C
whereAnswer > 0 and question_id in (1, 2)
group by projectCall_Recnum
) as C on pc.recnum = c.recnum
wherepc.removed = 0
andp.cancelled = 0
andp.deleted = 0
ands.closed = 0
ands.deleted = 0
andyear(getDate()) between year(P.startDate) and year(P.expDate)
Filtering in joins...
Code:
select...
FromtProject p with (noLock)
jointProjectCall pc with (noLock) on P.ID = pc.project_id
and pc.removed = 0
and p.cancelled = 0
and p.deleted = 0
and year(getDate()) between year(P.startDate) and year(P.expDate)

Hi there
i have a stored procedure like this:
CREATE PROCEDURE SP_Main
AS
SET NOCOUNT ON
BEGIN TRANSACTION
exec SP_Sub_One output
exec SP_Sub_Two output
IF @@ERROR = 0
BEGIN
-- Success. Commit the transaction.
Commit Tran
END
ELSE
Rollback Tran
return
GO
now the problem is, when i execute the stored procedure's inside the main stored procedure, and these sub sp's has an error on it, the main stored procedure doesnt rollback the transation.
now i can put the "begin transation" in the two sub stored procedure's. The problem is
what if the first "SP_Sub_One" executed successfully, and there was error in "SP_Sub_Two"
now the "SP_Sub_One" has been executed and i cant rollback it... the error occured in the
"SP_Sub_Two" stored procedure ... so it wont run ... so there will be error in the data
how can i make a mian "BEGIN TRANSACTION" , that even it include the execution of stored procedure in it.
Thanks in advance

Hi all,
Quick question in setting up a 3-disk SQL 7.0 system - can anyone think of a benefit to segregating a single RAID 5 disk array into numerous logical partitions for separating out the OS, the database files and the transaction logs? I would assume performance would be unaffected (as the drives are acting as a single array for reads & writes anyway) so other than general organization what (if any) advantage would be gained over making a single large logical partition?
TIA

I am reading about Buffer Pool Extensions, and how it stores data pages on media like an SSD, to speed up retrieval in future. Would this be useless if my mdf files are already on SSD media? At most, I envisage it meaning that instead of grabbing the data from the mdf, it would grab the data from the buffer pool extension drive, but if they are both on SSD's, I'm not sure of how much return I would see.
Has any user decided to use BPE when their data is already on SSD's, and have they noticed any improvement in these cases?
I am interested to hear if people think it would be a good idea to movethe Master & TempDB to a different HD.Here is my DB Server's set up:1. Processor: (1) AMD XP 28002. 1st HD (IDE 0) is the system & boot drive3. (3) SCSI HD make up a hardware RAID level 0 (striped withoutparity)solution - these striped drives are just for my working DBs4. (1) SCSI HD that's not doing anything.I want to put the Master & TempDB on the SCSI HD that's not doinganything. Would that be the best place for it for maximum performance orshould I put in the striped array. I am leaning more towards putting onthe SCSI HD that's not doing anything. What do you all think?Ed*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
View 1 Replies View RelatedWe have an application where part of the database is used for searching products and is very processor intensive due to the number of permutations and calculation that are required. This section of the database is scaled out by using transactional replication so that the €œsearch€? load is removed from central database€™s daily operations.
Each €œsearch€? server can handle around 15,000 search an hour with SQL taking about 3 seconds to return the result in XML (the system has be optimised to squeeze out every last bit of performance). This is in a 32bit environment. One other point, which is probably relevant, is that the Search data only totals 500MB.
With the possibility of upgrading these severs in the near future would we see any performance benefits in going 64bit. I know we won€™t take advantage of increased memory access due to the size of the search data but is there any discernable performance advantage between 32bit v€™s 64 bit processors and SQL Server 2005 64Bit. Or should I stick with SQL Workgroups and 32bit processor and save on the Standard SQL licence?
Many thanks

How do I search for and print all stored procedure names in a particular database? I can use the following query to search and print out all table names in a database. I just need to figure out how to modify the code below to search for stored procedure names. Can anyone help me out?
SELECT TABLE_SCHEMA + '.' + TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
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?

I have MSSQL 2005. On earlier versions of MSSQL saving a stored procedure wasn't a confusing action. However, every time I try to save my completed stored procedure (parsed successfully ) I'm prompted to save it as a query on the hard drive.
How do I cause the 'Save' action to add the new stored procedure to my database's list of stored procedures?
Thanks!
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!
Hello friends......How are you ? I want to ask you all that how can I do the following ?
I want to now that how many ways are there to do this ?
How can I call one or more stored procedures into perticular one Stored Proc ? in MS SQL Server 2000/05.
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

Hi,
Do you know how to write stored procedures inside another stored procedure in MS SQL.
Create procedure spMyProc inputData varchar(50)
AS
----- some logical
procedure spMyProc inputInsideData varchar(10)
AS
--- some logical
--- go
-------
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

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?

undefined P
The first returns a percentage for player wins, the second gives me a photo and sums the player winnings
I would like to combine the results so I can get the percentage and wininngs in one query, in another matter all together I would like create a procedure like the first but instead of returning only one player, I would like to return the percentage for each player
Thanks in advance for any light you can shine on this.
I have a question about stored procedures, Is it better to use stored procedures even if I only use it once at my site? Or is it better to write the sql-part directly in the sqldatasource?
And am I forced to create two different stored procedures even if they are exactly the same except the "Where-part"?
Now I have around 40 stored procedures, and quite many of them looks the same except the where-part...
(Iam just a beginner with SQL)

I am learning to make a ASP web site and feel that if i can do it the harder way using some stored procedures instead of using multiple datasources on each page requiring that it might be better. So i am wondering what are these used for:DECLARE vs just entering "@param1 varchar(30)"When i use "DECLARE @rc int" i get the error "Incorrect syntax near DECLARE"How to return values to ASP page in Visual Studio 2005 How to use @@rowcount - doesn't seem to work for me?i tried using DECLARE @rc intSET @rc = @@rowcountWhen to use GO, BEGIN etcIf i want to use the variable only in the procedure, and not needed to be inputed, do i need to put it in the CREATE PROCEDURE (section)?Should i use my own stored procedures or VS2005 created ones using datasources? not really procedures but SQL, in SQL can i do like IF ELSE? if i use my own i cant use the Optimistic Concurrency right? and whats that?
