I'm trying to write a recursive stored proc for the TreeView control that will return XML for the TreeView. Does anyone have any examples of code to do this or any resources that might help me write the stored proc?
Hi allI am implementing a stored procedure which needs to recursively callitself until specific condition is reached, Could anyone give someadvice about that?Thanks a lotRobert Song
I am having problem to apply updates into this function below. I triedusing cursor for updates, etc. but no success. Sql server keeps tellingme that I cannot execute insert or update from inside a function and itgives me an option that I could write an extended stored procedure, butI don't have a clue of how to do it. To quickly fix the problem theonly solution left in my case is to convert this recursive functioninto one recursive stored procedure. However, I am facing one problem.How to convert the select command in this piece of code below into an"execute" by passing parameters and calling the sp recursively again.### piece of code ############SELECT @subtotal = dbo.Mkt_GetChildren(uid, @subtotal,@DateStart, @DateEnd)FROM categories WHERE ParentID = @uid######### my function ###########CREATE FUNCTION Mkt_GetChildren(@uid int, @subtotal decimal ,@DateStart datetime, @DateEnd datetime)RETURNS decimalASBEGINIF EXISTS (SELECTuidFROMcategories WHEREParentID = @uid)BEGINDECLARE my_cursor CURSOR FORSELECT uid, classid5 FROM categories WHERE parentid = @uiddeclare @getclassid5 varchar(50), @getuid bigint, @calculate decimalOPEN my_cursorFETCH NEXT FROM my_cursor INTO @getuid, @getclassid5WHILE @@FETCH_STATUS = 0BEGINFETCH NEXT FROM my_cursor INTO @getuid, @getclassid5select @calculate = dbo.Mkt_CalculateTotal(@getclassid5, @DateStart,@DateEnd)SET @subtotal = CONVERT (decimal (19,4),(@subtotal + @calculate))ENDCLOSE my_cursorDEALLOCATE my_cursorSELECT @subtotal = dbo.Mkt_GetChildren(uid, @subtotal,@DateStart, @DateEnd)FROM categories WHERE ParentID = @uidENDRETURN @subtotalENDGORod
I am working with a large application and am trying to track down a bug. I believe an error that occurs in the stored procedure isbubbling back up to the application and is causing the application not to run. Don't ask why, but we do not have some of the sourcecode that was used to build the application, so I am not able to trace into the code. So basically I want to examine the stored procedure. If I run the stored procedure through Query Analyzer, I get the following error message: Msg 2758, Level 16, State 1, Procedure GetPortalSettings, Line 74RAISERROR could not locate entry for error 60002 in sysmessages. (1 row(s) affected) (1 row(s) affected) I don't know if the error message is sufficient enough to cause the application from not running? Does anyone know? If the RAISERROR occursmdiway through the stored procedure, does the stored procedure terminate execution? Also, Is there a way to trace into a stored procedure through Query Analyzer? -------------------------------------------As a side note, below is a small portion of my stored proc where the error is being raised: SELECT @PortalPermissionValue = isnull(max(PermissionValue),0)FROM Permission, PermissionType, #GroupsWHERE Permission.ResourceId = @PortalIdAND Permission.PartyId = #Groups.PartyIdAND Permission.PermissionTypeId = PermissionType.PermissionTypeId IF @PortalPermissionValue = 0BEGIN RAISERROR (60002, 16, 1) return -3END
I am having trouble executing a stored procedure on a remote server. On my local server, I have a linked server setup as follows: Server1.abcd.myserver.comSQLServer2005,1563
This works fine on my local server:
Select * From [Server1.abcd.myserver.comSQLServer2005,1563].DatabaseName.dbo.TableName
This does not work (Attempting to execute a remote stored proc named 'Data_Add':
When I attempt to run the above, I get the following error: Could not locate entry in sysdatabases for database 'Server1.abcd.myserver.comSQLServer2005,1563'. No entry found with that name. Make sure that the name is entered correctly.
Could anyone shed some light on what I need to do to get this to work?
Hi All,Quick question, I have always heard it best practice to check for exist, ifso, drop, then create the proc. I just wanted to know why that's a bestpractice. I am trying to put that theory in place at my work, but they areasking for a good reason to do this before actually implementing. All Icould think of was that so when you're creating a proc you won't get anerror if the procedure already exists, but doesn't it also have to do withCompilation and perhaps Execution. Does anyone have a good argument fordoing stored procs this way? All feedback is appreciated.TIA,~CK
I have an ASP that has been working fine for several months, but itsuddenly broke. I wonder if windows update has installed some securitypatch that is causing it.The problem is that I am calling a stored procedure via an ASP(classic, not .NET) , but nothing happens. The procedure doesn't work,and I don't get any error messages.I've tried dropping and re-creating the user and permissions, to noavail. If it was a permissions problem, there would be an errormessage. I trace the calls in Profiler, and it has no complaints. Thedatabase is getting the stored proc call.I finally got it to work again, but this is not a viable solution forour production environment:1. response.write the SQL call to the stored procedure from the ASPand copy the text to the clipboard.2. log in to QueryAnalyzer using the same user as used by the ASP.3. paste and run the SQL call to the stored proc in query analyzer.After I have done this, it not only works in Query Analyzer, but thenthe ASP works too. It continues to work, even after I reboot themachine. This is truly bizzare and has us stumped. My hunch is thatwindows update installed something that has created this issue, but Ihave not been able to track it down.
I've got an application where I need to traverse a "tree" of parent and child relationships. I've got code in my application that does this nicely, and I want to move it to the database in the form of stored procs for a little better performance. The initial way I created it, is that the stored proc creates a cursor for the parent nodes, then calls itself for each child node, and rips through it that way. The problem is is that I get a cursor already exists error. Am I doing something wrong, or is that a limitation of SQL server to only have one named cursor open at a time? Is there a better way to do this?
Hi, I would like some help on a stored recursive procedure I have been working on for my assigment. I had the solution from my course master some time back, but accidentally deleted the file before finishing the course, and would like the solution to that problem. The questions are as follows: 1) Create a recursive stored procedure that counts from 1 to 10 2) Create a recursive stored procedure that counts from 10 to 1
I believe there's more than one approach in solving these procedures, and any feeback is welcome.
How do I call my Stored Procedure recursively:CREATE PROCEDURE dbo.GetParentIONode(@IONodeID int,@FullNodeAddress char(100) OUTPUT)ASBEGINDECLARE @ParentIONodeID intIF EXISTS (SELECT ParentIONodeID FROM IONodes WHERE IONodeID = @IONodeID)BEGINSET @FullNodeAddress = CAST((SELECT ParentIONodeID FROM IONodes WHEREIONodeID = @IONodeID) AS VARCHAR) + ' / ' + @FullNodeAddress--CALL SP Again with @ParentIONodeID and @FullNodeAddress untilParentIONodeID = NULLSELECT @FullNodeAddressENDENDGO
The MLID in the header table will be generated automatically.All the Parents will be stored in the HEADER and their childs in the DETAIL.When a child is added to a parent,the Parent's MLID will be stored in the MLID field in the DETAIL table with the newly added child.That child will come to the PARENT table when a child is added to that.The MLITEM id in the parent table can be repeated when that item undergoes a rivision.But the MLID for this will be a new one.An item in the Parent Table can have any number of childs and these childs can have any number of children(there is no limit for the level.)
Now if i select an item id '1000' (for example from the Header Table) with a concatstring (it could be without a concat string also).all its childs and their children should be printed in a report like the following
************************************************** *************************** I NEED TO CREATE THE TREE USING BOTH THE HEADER(MSTHDRML) AND THE DETAIL TABLE(MSTDTLML) ************************************************** ***************************
How can this be done.Is it necessary to use a recursive function in a stored procedure to generate this ...... i have never used Recursive function in SQL SERVER Stored Procedures.Can anyone help me on this(with Code).if not stored procedure, then what else can be done for this.
I need to develope a stored procedure (eventually called by a trigger) that creates a record in an event table for all the descendants of a drawing. There are 3 tables involved as example tables shown below:
DwgTable
DwgID (integer)--drawing record identifier
PrntDwgID (integer)--parent drawing record identifier (a previously defined DwgID from this table)
DwgEventTable
DwgEventID (integer)--record identifier
DwgID (integer)--value from DwgTable
EventID (integer)--value from EventTable
EventTable
EventID There are other fields in two of the tables and only the fields shown in the DwgEventTable, but only the fields shown are required for adding a record in the DwgEventTable for a new event in the EventTable. The problem is identifying all the DwgID's of the descendant of the DwgID where the EventID occurred. There may be 0 to N descendants in 0 to N generations. I need to add a record for the original DwgID and all the descendant DwgID's in the DwgEventTable for the event identified by EventID.
I could do this from the client side, but a better place would be from the server side. I need some clue(s) on how to start coding a recursive stored procedure in SQL Server 2005. From what I have read, you cannot create a managed code procedure that appends or updates records--if managed code can add/modify records then I can do the above with managed code procedure.
I apologize if I posted in the wrong section, but I cannot find a solution to this. I was hoping that some one can help me figure this out. I need this solution in a stored procedure VS using dataset because there are thousands of categories and it is extremely slow with a dataset. I have a category table ID intPARENTID intNAME SAMPLE DATA:
ID NAME PARENT_ID
1 ANIMALS 0
2 DOGS 1
3 CATS 1
4 Abyssinian 3
5 Persian 3
6 Rurkish Van 3
7 Dalmation 2
8 German Shepherd 2
9 Irish Setter 2
10 Bulldog 2
I need the stored proc to return results in a single record set like this: ANIMALS - DOGS - - Dalmation - - German Shepherd - - Irish Setter - - Bulldog - CATS - - Abyssinian - - Persian - - Turkish Van Seems fairly easy but I have been battling with this for days now. Thank you in advance, EL
I have a stored procedure "uspX" that calls another stored procedure "uspY" and I need to retrieve the return value from uspY and use it within uspX. Does anyone know the syntax for this?
I have about 5 stored procedures that, among other things, execute exactly the same SELECT statement
Instead of copying the SELECT statement 5 times, I'd like each stored proc to call a single stored proc that executes the SELECT statement and returns the resultset to the calling stored proc
The SELECT statement in question retrieves a single row from a table containing 10 columns.
Is there a way for a stored proc to call another stored proc and gain access to the resultset of the called stored proc?
I know about stored proc return values and about output parameters, but I think I am looking for something different.
I would like to know if the following is possible/permissible:
myCLRstoredproc (or some C# stored proc) { //call some T SQL stored procedure spSQL and get the result set here to work with
INSERT INTO #tmpCLR EXECUTE spSQL }
spSQL (
INSERT INTO #tmpABC EXECUTE spSQL2 )
spSQL2 ( // some other t-sql stored proc )
Can we do that? I know that doing this in SQL server would throw (nested EXECUTE not allowed). I dont want to go re-writing the spSQL in C# again, I just want to get whatever spSQL returns and then work with the result set to do row-level computations, thereby avoiding to use cursors in spSQL.
Hello, I am hoping someone can help me in this. I am looking to write a stored procedure that will return the heirarchy of an organization. I will display how the heirarchy might look and then list the tables involved.
John Smith
- Jacob Jones - Lisa Thompson - Samuel Barber
- Paul Smith - John Jackson
Ok, so Jacob, Lisa, an Samuel report up to John Smith. Paul and John Jackson report up to Samuel Barber.
Here are the tables:
Users holds the user_id, first_name, last_name, and reports_to_user_id. User_Roles holds the user_id, role_type_id Role_Types holds the role_type_id, and the type (which could be Administrator, Standard, Guest) for example. In addition, Role_Types also has ranking which must be taken into consideration as well. 1 being the top rank and 9 being the lowest.
I am calling a stored procedure (say X) and from that stored procedure (i mean X) i want to call another stored procedure (say Y)asynchoronoulsy. Once stored procedure X is completed then i want to return execution to main program. In background, Stored procedure Y will contiue his work. Please let me know how to do that using SQL Server 2000 and ASP.NET 2.
Hi Peeps I have a SP that returns xml I have writen another stored proc in which I want to do something like this:Select FieldOne, FieldTwo, ( exec sp_that_returns_xml ( @a, @b) ), FieldThree from TableName But it seems that I cant call the proc from within a select. I have also tried declare @v xml set @v = exec sp_that_returns_xml ( @a, @b) But this again doesn't work I have tried changing the statements syntax i.e. brackets and no brackets etc..., The only way Ive got it to work is to create a temp table, insert the result from the xml proc into it and then set @v as a select from the temp table - Which to be frank is god awful way to do it. Any and all help appreciated. Kal
I didn't want to maintain similar/identical tables in a legacy FoxPro system and another system with SQL Server back end. Both systems are active, but some tables are shared.
Initially I was going to use a Linked Server to the FoxPro to pull the FP data when needed. This works. But, I've come up with what I believe is a better solution. Keep in mind that these tables are largely static - occassional changes, edits.
I will do a 1 time DTS from FP into SQL Server tables.
I then create INSERT and UPDATE triggers within FoxPro.
These triggers fire a stored procedure in FoxPro that establishes a connection to the SQL Server and fire the appropriate stored procedure on SQL Server to CREATE and/or UPDATE the corresponding table there.
In the end - the tables are local to both apps.
If the UPDATES or TRIGGERS fail I write to an error log - and in that rare case - I can manually fix. I could set it up to email me from within FoxPro as well if needed.
Here's the FoxPro and SQL Server code for reference for the Record Insert:

I am trying to create a stored proc, that delivers a recordset, per the user requirements BUT,
I want to create a Geneirc search Proc that can handle a few criteria
I was wondering if it is possible to create a VB like Select case depending on Information supplied to the stored proc
i.e @Loc_Thing @Loc_OtherThing
SELECT FirstName,LastName,CIty,Job,,Company,Webpage FROM RECORDSET WHERE Select case @Loc_Thing Case "Mickey" LastName = @Loc_OtherThing Case "Walt" Company = @Loc_OtherThing
...... etc
is it possible to create a strored proc like this? I have found a Select case in SQL, but it doesn't work I would like it? Any Idea's?
Hello, So I created my first SP today which returned data to populate a datagrid. Worked to perfection. Now I'm trying to do a simple login and I'm having a hard time getting it together. I want the user to enter in a username and pass then if user exists, to return their userid and update their last login date. But I can't get it. Any help would be awesome.
Here's my SP...
CREATE PROCEDURE [dbo].[userLogin] @username varchar(50), @pass varchar(50) AS
declare @x int declare @userid int
if exists (SELECT userid FROM users WHERE username = @username AND password = @pass) set @x = 1 else set @x = 0
if @x = 1 UPDATE users SET lastlogin = getdate() WHERE userid = (SELECT userid AS name FROM users WHERE username = @username AND password = @pass) else return '0'
if @x = 1 SET @userid = (SELECT userid FROM users WHERE username = @username AND password = @pass) return @userid GO
Any constructive criticism on my SP is welcome. Also, should I be using Print or Return if I want to send back a value to my VB code?
And my VB:
Dim user As String = txtUsername.Text Dim pass As String = txtPassword.Text Dim objDataSet As DataSet Dim objAdapter As SqlDataAdapter
Try Dim cmd As New SqlCommand
'Enter Param's here Dim myParam1 As SqlParameter = cmd.Parameters.Add("@username", SqlDbType.VarChar) Dim myParam2 As SqlParameter = cmd.Parameters.Add("@pass", SqlDbType.VarChar)
Dim str As String = cmd.Parameters("@userid").Value() cmd.ExecuteNonQuery() If str = "0" Then 'Error Login Page Response.Redirect("login_err.aspx") Else Session("userid") = str Response.Redirect("home.aspx") End If
Table2 has the same ID field and a date field which are both unique (PK, FK)
I need to write a stored procedure that will query the ID field from table1 like
Select distinct(id) from Table1
Would return:
ID
1
2
3
4
5
Now on the first of every month I want a job to run that would create a new record for EACH ID from the above query. The new record would be created in Table2 with the ID and a date (that I will determine), resulting in:
ID DATE
1 01/01/06
2 01/01/06
3 01/01/06
4 01/01/06
5 01/01/06
The following month, after running it again, the table would look like:
ID DATE
1 01/01/06
1 02/01/06
2 01/01/06
2 02/01/06
3 01/01/06
3 02/01/06
4 01/01/06
4 02/01/06
5 01/01/06
5 02/01/06
I have no idea how to “loop� through this record set for each record in Table1 and in turn insert into Table2.
I have a current stored proc that creates records based on certain criteria. One of the fields I have is a SmallDateTime field. To populate this from my stored proc, I have this code (for this one field).
SELECT @myLeaveDate = CAST(STR(MONTH(getdate()))+'/'+STR(01)+'/'+STR(YEAR(getdate())) AS DateTime)
This always creates a record for the 1st of the current month. This works fine as is. After it runs I can look at the table and it creates dates that look like the following: “2/1/2006� -Notice it doesn’t have any minutes, seconds, etc.
Now what I need is to do something similar in another field which is also SmallDateTime, BUT I want the date to be for the 10th day of the following month.
I got this working using dateadd, but it also appends the minutes, seconds, etc.
