I'm writing some stored procedures that first do an Insert or an Update, and then also do a Select to return a Recordset back to an ADO client. However an Insert or Update causes a closed recordset to be produced in ADO. I can skip over the closed recordset with the NextRecordset method.
So the question is, is there any way of stopping the closed recordset being returned? I don't want to have to call the NextRecordset method from ADO as this would mean that the client would need to know about the implementation of the stored procedure.
Has anyone got any ideas on how to get round this?
I've read that stored procedures should use output parameters instead ofrecordsets where possible for best efficiency. Unfortunately I need toquantify this with some hard data and I'm not sure which counters touse. Should I be looking at the SQL Server memory counters or somethingelse.*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
I was wondering, is there any way to have a stored procedure write to a file its resultant recordset?
i.e. I have this SP which fires a query, this in turn returns a single row recordset that I need to have written to a file. I realise this could easily be facilitated using an ADO client, however, can it be done by the backend i.e. the SQL7 & SP itself, directly?
I hope you can help me here! thanks for your time! Cheers Gaurav
I am working on a C# stored procedure for SQL 2005, and i've uncovered a couple questions.
First a description of the procedure:
I have a series of equations taking place to calculate a score based on activities in which the user participated in, that will give them an over all grade or rating. The calculations currently take place in the database, and I am moving this from T-SQL to C# CRL.
1. In order to connect the stored procedure to the database I use a SqlConnection and a SqlCommand to execute either dynamic sql or a stored procedure to return data to a data reader. Is there an easier way to connect to the database? In SSMS if i open up the query it knows what database i am connected to. Do I have to make a sql connection in C# stored Procedures?
2. I have multiple functions within the main C# Stored Procedure that I'm working on. This ends up requiring Multiple Active Recordsets. I must set this withing the connection string. Seeing as I'm using a named instance of SQL 2005, I now must put the userid, password, and server name into the code. Is there a more secure way to connect to SQL Server in a C# Stored procedure that allows MARS?
3. I encryped the connection string, and put it into the assembly, I wrote a decryption class, and in the procedure itself everytime I need to refrence the connection string, I call it, decrypt it, and pass it along. But my code to decrypt the connection string is in the compiled DLL, if the server was ever compromised the encrypted connection string and the key to decrypt it are sitting in the DLL. Is there a config file that I can use for C# Stored Procedures?
4. If I have to keep the connection string in the file, then I need to change that per environment. Example I have 3 test environments before production. So I would need to change the connection string for each file. That may be fine for one procedure, but what if I have 20, that will quickly get of hand?
5. Along the security lines, can the assembly for a C# Stored Procedure be called from outside the assembly? From a command prompt, or by a maliceous program? Or could it be called directly by a .NET application instead of going through a T-SQL Stored Procedure that is using WITH EXECUTE AS CALLER AS EXTERNAL NAME [PROJECTNAME].[CLASSNAME].[METHODNAME]
I have written a stored proceedure for MSSQL that needs to run for hours ata time. I need to execute it from C++ code. The current code does:nRet = SQLDIRECTEXEC(hstmt, "exec stored_proc", SQL_NTS)followed shortly after by aFree_Stmt_Handle(hstmt) //roughlyThe stored proc currently dies with the statement handle, not fullypopulating the table I need it to.I need to either know when the proc finishes so I can close the handle afterthat, or allow the proc to run independently on the server no matter whatthe program is doing (is exited, etc), either of these is fine.Please Help! Thanks in advance!Joseph
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.
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?
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?
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"?
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)?
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?
is it possible to concatenate 2 recordsets ? i have 2 select, and i need then to be displayed one after other.using union all the results are gathered, ordered like only one select.thanks for all
I've written a query which needs to return different records depending on its argument.
I've used an IF statment to test which of the three SELECT statments should be returned. However, when I try to access the data from VBA in Access I find that the recordset is empty, whereas the query returns thr correct data if I run it in the SQL environment. WHy is this? More importantly, how do I make it return records?
Code:
ALTER PROC [dbo].[spFilteredContractListByUser]
@UserID varchar(7) --The user's 'T' number
AS
PRINT 'User ID is' + @UserID
--Get this user's filter type from tbl
DECLARE @FilterType int
SELECT @FilterType = FilterID FROM tblFindContractUserFilter WHERE UserID = @UserID
-- Standard filter -- Returning all queries matching the username IF @FilterType = 1 BEGIN SELECT DISTINCT [Acc No], Business, Type, [Log Date], [Logged By], [Ack. Date], [Ack. By], [Late?] FROM qryQueriesWorkList WHERE (suser_sname = @UserID) END ELSE IF @FilterType = 2 -- Return only queries acknowledged by @UserID BEGIN SELECT DISTINCT q.[Acc No], q.Business, q.Type, q.[Log Date], q.[Logged By], q.[Ack. Date], q.[Ack. By], q.[Late?] FROM qryQueriesWorkList q WHERE (q.[Ack. By] = dbo.getEmployeeName(@UserID)) END ELSE IF @FilterType = 3 -- Return all the queries which have not been acknowledged BEGIN SELECT DISTINCT q.[Acc No], q.Business, q.Type, q.[Log Date], q.[Logged By], q.[Ack. Date], q.[Ack. By], q.[Late?] FROM qryQueriesWorkList q WHERE (q.[Ack. By] IS NULL) END
I need to decrease the amount of time it takes to return a set of data of the following format:
State[Provided vai user intput]->All Counties in State->All Cities in County->All Zones in City[usually < 50 or 75 per city]
current behavior: 1. currently user selects state all counties are returned from db 2. foreach county cities are returned 3. foreach city streets are returned 4. objects hydrated with data & display drawn
As you can see this gets expensive. I know there has to be a better way to do this. Any suggestions? We use sql server/c#.net.
I'm having SSIS block right now and thought I'd see if anyone had a simple solution to this.
What I have is SSN data coming in from several different tables, which needs to be inserted into a SurrogateSSN table which just uses an Identity field for the surrogate.
I normally build a seperate package for each detination table, so in each package that has SSN data in the source, I need to insert into the SurrogateSSN table (then I can use the surrogate values later in my package).
What I'm looking for is a simple solution if possible (preferrable using existing non-script tasks, or very short script), where I can pass in the SSN. Is there way to create a package that will accept a recordset (of SSN's) for this insert, that I can call from several different packages, and pass in the recordset of SSN's?
I think it whould be simpler to explain what I am trying to accomplish. I wish to pull a query to return multiple records from a SQL 7.0 database. The query is a customers standing order. I wish to make edits to multiple records then return those records for update. The HTML pages that I have seen all seem to display tables on a singular record format. Is it possible to display records in a 'Table' format and allow it to be updated. Can any one answer this or direct me to a site with the relevent info. Thanks Stuart Indtec@eircom.net
Using just SQL (within SQL Server 2000), I'm looking to output 2 (or more) recordsets from a one-to-many join between table all on one row. Help! Can someone please show me how to do this if it can be done.

Here's a question you'll never quit hearing: is there a convenient way to page through large recordsets in SQL Server 2000?
I'm writing some software which, for all intents and purposes, works like a messageboard: users can create threads, leave replies, and so on.
I have about a half million records in a few of my tables, and some of my queries return 1000s of results. I'd prefer not to return 1000s of records all at once, so I don't want to page my records in code; I'd rather page them in SQL Server. Naturally, I want to page replies. However, I don't know of a convenient way to page records in SQL Server 2000.
I have a single .asp page that opens a connection and then sequentiallyopens and closes 14 recordsets from stored procedures to obtain variousproduct information before closing the connection.Is it common practice to do something like this? Or is opening 14recordsets going to become a real problem when the page goes live and startsgetting high web traffic?Thank you in advance for any information you might provide.Dave
Hey,I've got an Classic ASP app pulling some records out of a DB, whichworked fine when it was Access. When we upped to SQL Server, all of asudden, when the Recordsets came back, all the dates were empty, eventhough the data was showing up in the DB.About a year ago (only code asp apps once and a while), I rememberseeing this and finding something that just had something to do with theorder in which something was being referenced, but I just can't for thelife of me remember what it was.The Dates are set as datetime, length of 8.Anyone know why this happens and a solution?many thanks,rob
I am doing some mods to an existing db web app in asp. I am providing a facility to copy a subset of related records in a few tables. I am using one recordset to read in the selected records and then copying the data into another recordset creating a new record in the same table. I have to then pick up the @@IDENTITY of the new record so that I can update linked records in other tables.
The @@IDENTITY value returned is null unless I close the selection recordset.
I have created a simplified version of the code to demonstrate this.
The underlying table is called 'test' and it has 2 fields, 'test_id', integer, identity and 'test_desc' varchar(50)
ASP Code

sub CloseDatabase Set objRS1 = Nothing Set objRS2 = Nothing objConn.Close Set objConn = Nothing end sub
