Problem When Invoking Stored Procedure With Cursor From Inside .net
Nov 7, 2007
Dear all,
i'm facing a problem with my storedprocedure which happened when i ran my web application and reach to the point where my class invoke this storedprocedure,
my SP contains a cursor that built his sql according to certain condition, so i put the "SET @cur Cursor For....." inside the if block (definitely i've declared it under AS keyword directly) and this SP is working well inside sql server(I've tested it), BUT when my ASP.net code invoke this SP it gives me the following error :
"The Variable @cur does not currently have a cursor allocated to it" repeated as much as there are IF clauses in my SP,
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?
Just wonder whether is there any indicator or system parameters that can indicate whether stored procedure A is executed inside query analyzer or executed inside application itself so that if execution is done inside query analyzer then i can block it from being executed/retrieve sensitive data from it?
What i'm want to do is to block someone executing stored procedure using query analyzer and retrieve its sensitive results. Stored procedure A has been granted execution for public user but inside application, it will prompt access denied message if particular user has no rights to use system although knew public user name and password. Because there is second layer of user validation inside system application.
However inside query analyzer, there is no way control execution of stored procedure A it as user knew the public user name and password.
Looking forward for replies from expert here. Thanks in advance.
Note: Hope my explaination here clearly describe my current problems.
I have written a SQL CLR procedure, which will be invoking the webservice..I developed the application locally and it works fine, I am able to invoke the webservice using the SQL CLR procedure present in my database. But when i hosted the webservice in App server and executed the SQL CLR procedure in DB Server. From DB Server, I am not able to invoke the webservice present in the app server. But i am able to browse the webservice from my db server. I am getting the foolowing error message
A .NET Framework error occurred during execution of user defined routine or aggregate 'usp_LoadView': System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond System.Net.Sockets.SocketException: at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.InternalConnect(EndPoint remoteEP) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Int32 timeout, Exception& exception) System.Net.WebException: at StoredProcedures.usp_LoadView(String ConnectionString, String WebserviceUrl, String ColumnMappingsXml, SqlXml AddressXml, SqlXml& ExceptionSqlXml, Int32& ErrorStatus)
I goggled and tried out various options, like increasing €œwebservice timeout€? and increasing €œexecutiontimeout€? for HttpRuntime, but none seems to be working. Please provide me your suggestions to how to fix this..
hi all, i'm wondering if i can use one stored procedure in too cases, this is the senario: i have stored procedure for admin and another one for user, they have the same select everything is the same except that in admin SP i have where @admin = admin and for user i have where @user = user if there a way to use if and else to make this happen this is what i did so far:
CREATE PROCEDURE [test] @admin INT, @user INT, @indexType INT as if @indexType = 1
begin
SELECT * FROM table WHERE something IN (SELECT * FROM anothertable where admin = @admin) end else begin SELECT * FROM table WHERE user = @user end GO
I want to execute some insert statements within a stored procedure and commit those changes regardless of any raiseerror that occurs later in the stored procedure. My difficulty is that I am forced to use raiseerror with severity 16 in order to send a message through the powerbuilder application interface (compiled vendor code). I have tried save points but can't get that to save my insert and still present an error to the user about something else that happens later.
here is an example
BEGIN procedure
Insert something and save it even if error is raised below
RaiseError('you made a mistake and need to do this.',16,-1)
Hi folks I nead to call a stored procedure in a where statemene, but MSSQL dont like that.
My problem is that the StoredProcedure is calling itself recursive and therfore its impossible to add the code as a standard SELECT statement. Here is the code
ALTER PROCEDURE dbo.advsp_FilterRecordRights @RequesterGUID Char(20), @EntityGUID Char(20) AS BEGIN if not Exists(Select *
from GUIDRightsH where GUIDRightsH.EntityGUID = @EntityGUID and
GUIDRightsH.RequesterGUID = @RequesterGUID and GUIDRightsH.RecProp <> 0) Begin
Return 1 end
if not Exists(Select *
from UsergroupMembers where UserGroupMembers.UsergroupGUID = @RequesterGUID and dbo.advsp_FilterRecordRights(UserGroupMembers.UserGUID,@EntityGUID) = 1) Begin
Basically I have two strings. Both strings will contain similar data because the 2nd string is the first string after an update of the first string takes place. Both strings are returned in my Stored Procedure For example:String1 = "Here is some data. lets type some more data"String2 = "Here's some data. Lets type some data here"I would want to change string2 (inside my Stored Procedure) to show the changed/added text highlighted and the deleted text with a strike though. So I would want string2 to look like thisstring2 = "Here<font color = "#00FF00">'s</font> <strike>is</strike> some data. <font color = "#00FF00">L</font>ets type some <strike>more</strike> data <font color = "#00FF00">here</font>" Is there an way to accomplish this inside a stored procedure?

I try to join in the table mb_personal here. Some help would be very appreciated! Thanks.
Hello, I have a situation that I query a table and return multiple rows (email addresses). I want to iterate through the rows and concatenate all email addresses into one string (will be passing this to another stored procedure to send mail). How can I process result rows inside a stored procedure? This is what I have so far: CREATE PROCEDURE [dbo].[lm_emailComment_OnInsert] @serviceDetailID int,@comment varchar(500),@commentDate DateTime,@commentAuthor varchar(100)ASBEGINDECLARE @serviceID intDECLARE @p_recipients varchar(8000)DECLARE @p_message varchar(8000)DECLARE @p_subject varchar(100)/* Grab the Service_id from underlying Service_Detail_id*/SELECT @serviceID = Service_id FROM lm_Service_Detail WHERE Service_Detail_id = @serviceDetailID/* Get email addresses of Service Responsible Parties */ SELECT DISTINCT dbo.lm_Responsible_Party.EmailFROM dbo.lm_Service_Detail INNER JOIN dbo.lm_Service_Filing_Type ON dbo.lm_Service_Detail.Service_id = dbo.lm_Service_Filing_Type.Service_id INNER JOIN dbo.lm_Responsible_Party_Filing_Type ON dbo.lm_Service_Filing_Type.Filing_Type_id = dbo.lm_Responsible_Party_Filing_Type.Filing_Type_id INNER JOIN dbo.lm_Responsible_Party ON dbo.lm_Responsible_Party_Filing_Type.Party_id = dbo.lm_Responsible_Party.Party_idWHERE (dbo.lm_Service_Detail.Service_Detail_id = @serviceDetailID)/* Build message */ SET @p_subject = "KLM - Service ID: " + CAST(@serviceID AS varchar(4))SET @p_recipients = "" /*need string of addresses*/
I am having problem with 'TOP @pageSize'. It doesn't work, but if I replace it by 'TOP 5' or 'TOP 6' etc., then the stored procedure runs without errors. Can someone please tell me how I could use @pageSize here so that it dynamically determines the 'n' of 'TOP n' ?
ALTER PROCEDURE dbo.spGetNextPageRecords
( @pageSize int, @previousMaxId int
)
AS /* SET NOCOUNT ON */ SELECT Top @pageSize ProductId, ProductName FROM Products WHERE (ProductID > @previousMaxId) order by ProductId RETURN
CREATE PROCEDURE SelectCostumers @name varchar(100) Declare @SQL = "SELECT Id, Name FROM Costumers" AS IF (@name IS NULL) @SQL ELSE @SQL += "WHERE Name LIKE @name"
See, what I need is a string variable that I can concatenate with whatever I want depending on the parameter I get.
I am trying to creating a table inside a stored procedure using SQL that works fine in Query Analyzer. However, when I check the syntax I get the following message:
SELECT B.COMPONENT, TOT_OPTIONS_EXCHANGED = SUM(A.UNITS) FROM TBLEXERCISEOPTIONS A, TBLCOMPONENT B WHERE B.COMPONENTID = A.COMPONENTID GROUP BY B.COMPONENT
GO
Any help getting this to run correctly would be appreciated.
I have a cursor inside a stored procedure that should identify rows based on certain criteria and update the columns on those records.
While I try to do so, the cursor goes into an infinite loop although I have only 1 record that matches my criteria. I think that the transaction is not commited and the cursor is picking up the same record for update.
Here is my sample record in table :tblMsg SenderRef <space> MsgStatusId <space> MsgType <space>Groupid 1281341<space> 1 <space>KBC-NON-ETC-MATCHED-BLIM <space>191902
DECLARE @blimGroupId AS INT DECLARE @admSenderRef AS VARCHAR(50)
DECLARE admCursor CURSOR FOR SELECT senderref FROMtblMsg WHERE msgstatusid = 18 AND msgtype = 'KBC-RCVD-ADM' FOR UPDATE
OPEN admCursor
FETCH NEXT FROM admCursor INTO @admSenderRef
WHILE @@FETCH_STATUS = 0 BEGIN --FIND CORRESPONDING BLIM RECORD AND GRAB ITS GROUPID TO UPDATE THE ADM SELECT @blimGroupId = GroupID FROM tblMsg WHERE msgType = 'KBC-NON-ETC-MATCHED-BLIM' AND SenderRef = @admSenderRef PRINT 'AFTER SELECT INSIDE WHILE: Senderref- >' + @admSenderRef; --UPDATE THE ADM RECORD WITH THE GROUPID AND MSGSTATUS = 3 BEGIN UPDATE tblMsg SET MsgStatusId = 3, GroupId = @blimGroupId WHERE CURRENT OF admCursor END PRINT 'AFTER UPDATE INSIDE WHILE'; END
CLOSE admCursor DEALLOCATEadmCursor
The update statement was included beteween a BEGIN TRAN and END TRAN. But no joy.
Okay, so I have a problem and I would be REALLY grateful for anyassistance anyone can offer because I have found little or no help onthe web anywhere.I want to access and do joins between tables in two different SQL db'son the same server. Heres what Im dealing with.In one database resides all of my security features for our clients,where it decides who can login, etc etc....In another database, I need to cross reference with a few fields in mysecurity db.See the issue Im running into here is that because the way the peoplehave their databases set up for different products, I would normallyhave to put these tables with security features in every database...which is horrible, because every time I do an update I would have todo it in 12 different places. Thats not efficient at all.So I thought if I had one central DB, where all security features arecontrolled from, that would be perfect... now the issue is crossreferencing and doing joins with other tables that ARENT in the samedb....have I lost you yet?I appreciate all of your help!THANKS!!
I have to write a stored procedure what repair a table. It have to delete lost rows before make relation to itself (PK column is 'Kw_KeywordID', FK column is 'Kw_ParentID'). I do not found the way to write this procedure to can create statement from parameter of the procedure. I would like to pass the table name, but I receive error if the query like 'Select ... Form @Table ....'. If the parameter is in the 'WHERE', nothing problem.
My procedure is: CREATE PROCEDURE sp_Repair_IS_KW_AbtKz176 AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON;
declare @OrphanRowCount int select @OrphanRowCount = 1
while(@OrphanRowCount > 0) begin DECLARE KWCursor CURSOR FOR SELECT count(*) AS cRowCount FROM IS_KW_AbtKz176 WHERE Kw_ParentID IS NOT NULL AND Kw_ParentID NOT IN (SELECT Kw_KeywordID FROM IS_KW_AbtKz176);
OPEN KWCursor; FETCH NEXT FROM KWCursor INTO @OrphanRowCount CLOSE KWCursor DEALLOCATE KWCursor
IF (@@FETCH_STATUS = 0) AND (@OrphanRowCount > 0) BEGIN exec('DELETE FROM IS_KW_AbtKz176 WHERE Kw_ParentID IS NOT NULL AND Kw_ParentID NOT IN (SELECT Kw_KeywordID FROM IS_KW_AbtKz176)') END end END GO
How can I run fully parameterized queries from an SP. I can make it only like exec('DELETE FROM' + @TableName + ...)
I want to use a stored procedure inside Sql Server from my aspx page so that the data entered in the form goes to the database after submit.
My stored procedure (inside the SQL Server) inserts several fields in a table and it returns two variables. What code I need to write in order to pass the data from the form to the stored procedure inside the Sql Server? And to store the two returned values?
Hi, I'm new to ASP.NET 2.0. I have a sqldatasource and a formview controls on a web page and inside the formview control I have two textboxes. When I click the UPDATE button in the formview, I'd like to be able to retrieve the values of the textboxes inside the formview control and pass these values to a 'Update' SQL stored procedure defined in the Sqldatasource. Does anyone know how I can do this? Hope my question is clear. Thanks in advance. hakl
I have a stored procedure that basically recieves the where clause of a select statement and executes the new sql statement... ie:
CREATE PROCEDURE [dbo].[bsa_GetImportIDs] (@FilterText varchar(1000)) AS
DECLARE @MySQL varchar(1000)
SET @MySQL = "SELECT Import_ID FROM tblImport WHERE " + @FilterText
EXEC (@MySQL) GO
Now, in another stored procedure, I need to use the stored procedure above in a cursor so that I can execute an insert statement for each occurance of the Import_ID that appears in that dataset... ie:
CREATE PROCEDURE [dbo].[bsa_PutLargeCase] AS
DECLARE @CaseID uniqueidentifier SET @CaseID = NewID() Declare @ImportID uniqueidentifier
Declare curClient Cursor FAST_FORWARD for SELECT Import_ID FROM dbo.bsa_GetImportIDs (@FilterText) <---- this does not work!!!
Open curClient FETCH NEXT FROM curClient INTO @ImportID WHILE @@FETCH_STATUS = 0 BEGIN
EXEC dbo.bsa_PutCaseDetail @CaseID, @ImportID
FETCH NEXT FROM curClient INTO @ImportID END
CLOSE curClient DEALLOCATE curClient
GO
How can I utilize my first stored procedure in the cursor of the second? ... or Are there any other approaches that may be a better solution to what I am trying to accomplish?
any of you have an idea how i can declare an output parameter for my cursor which is inside a stored procedure. i would lik to see the output using the exec command but i don't know how to get the out from my cursor. please help!

Hi, I have two tables A and B. In table A i have three columns called empid, empname and empsalary where empid is an identity column. Table A has some records filled in it. Table B has the same schema except the fact that the empid is not an identity column in table B. Table B does not contain any rows initially. All other aspects remain the same as that of table A. Now i am going to delete some records in table A based on the empid. When i delete the records in table A based on empid the deleted records should be inserted into table B with the same empid. I need to accomplish these two tasks in a single stored procedure. How to do it? I need the entire code for the stored procedure. Please help me. I am trying for the past 4 days. Thanx in Advance
I need to run a sequel statement in a stored procedure and get if it found any records because the next statements depend on if records were found or not. How do I do this?
In the below procedure definition, i need to find a way parse the definition and get the list of places where the where clause is being used.
SELECT DISTINCT FC.CASE_ID, UPPER(FC.CASE_NUMBER) AS CASE_NUMBER, UPPER(REPLACE(FC.CASE_SHORT_TITLE,CHAR(13)+CHAR(10),'')) AS CASE_SHORT_TITLE, FC.CASE_STATUS_DESCR, FC.CASE_TYP_DESC, FC.CASE_SUB_TYP_DESC,
[Code] ....
In the above query there are more than one places and the where clause may not have the same string the where clause it can be with a space between the "=" and the value in single quotes.
Result set should be in the below format:
TABLE NAME Column Name VALUE CFG_ELEMENTS ELEMENT_NAME REPORT_CONSOLIDATEDCASES_CASERELATEDTYPID
I was wondering if anyone can explain the positives and negatives of using a single stored procedure that contains one or more distinct queries. I know there are problems with dynamic SQL but I am not proficient enough to know whether this falls under that umbrella.
For clarification, what I am referring to is this: In a single stored procedure, I have a parameter called Query_ID that is used to identify which query in the sproc that I want to execute. Then from my ASP page, I simply pass the appropriate value for Query_ID. So:
IF @QUERY_ID = 1 BEGIN SELECT [whatever] FROM [tbl1] WHERE [conditions] GROUP BY [something] ORDER BY [somethingelse] END ELSE IF @QUERY_ID = 2 BEGIN SELECT [whatever] FROM [tbl2] WHERE [conditions] GROUP BY [something] ORDER BY [somethingelse] END END
