How To Call Via CLR One Dll Which Calls Two Webservices (endpoints) With Dynamic Parameter
May 23, 2007
I developed one DLL in vb .Net which call two web services (sql endpoints) I wish to use this solution but for hundreds of servers (endpoints) I want to ask if I could do that with dynamic parameters passed to de DLL CALL in sql server clr.
Actually when I compile de DLL I need to have referenced (hardcoded) the webservices (endpoints) and when I need a brand new endpoint I need to reference it, compile the dll and release.
I cannot find how to invoke the service within the DLL with the namespace or webservice name as parameter.
Mi code to invoke now my referenced end point is: (note that my endpoint name is rperez)
Dim CallWebService As New rperez.IntelisisServiceEndPoint
CallWebService.Credentials = System.Net.CredentialCache.DefaultCredentials
Call CallWebService.IntelisisService(ArchivoOriginal)
My class rperez.IntelisisServiceEndPoint is referenced (hardcoded) in the dll project I need it dynamic
Do I need to change my code to PROXY object ?

All -
I have a SQL Server 2005 HTTP endpoint. I create a transaction scope in a client application and call two methods on that endpoint. Will the operations performed in the two methods, really, be in a transaction?
In other words, will SQL Server enlist in the ambient transaction even when I am accessing it through a HTTP endpoint?
Thanks.

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:
FOXPRO employee.dbf InsertTrigger:
employee_insert_trigger(VAL(Employee.ep_pk),Employ ee.fname,Employee.lname,Employee.email,Employee.us er_login,Employee.phone)
FOXPRO corresponding Stored Procedure:
FUNCTION EMPLOYEE_INSERT_TRIGGER
PARAMETERS wepk,wefname,welname,weemail,WEUSERID,WEPHONE
nhandle=SQLCONNECT('SS_PDITHP3','userid','password ')
IF nhandle<0
m.errclose=.f.
IF !USED("errorlog")
USE tisdata!errorlog IN SELECT(1)
m.errclose=.t.
ENDIF
SELECT errorlog
INSERT INTO errorlog (date, time, program,source,user) ;
values (DATE(), TIME(), 'EMPLOYEE_INSERT_TRIGGER','nhandle<0 PARAMS: '+STR(wepk)+wefname+welname+weemail+WEUSERID+WEPHO NE,GETENV("username"))
IF m.errclose
USE IN errorlog
ENDIF
RETURN
ENDIF
nquery="exec ewo_sp_insertNewEmployee @WEPK ="+STR(wepk)+",@WEFNAME ='"+wefname+"',@WELNAME ='"+welname+"',@WEEMAIL ='"+weemail+"',@WEUSERID ='"+weuserid+"',@WEPHONE='"+wephone+"',@RETCODE =0"
nsucc=SQLEXEC(nhandle,nquery)
SQLDISCONNECT(nhandle)
IF nSucc<0
m.errclose=.f.
IF !USED("errorlog")
USE tisdata!errorlog IN SELECT(1)
m.errclose=.t.
ENDIF
SELECT errorlog
INSERT INTO errorlog (date, time, program,source,user) ;

I'm expecting to revamp some stored procs so that their selects are executed on a dynamic string that always returns the same columns but varies the sources.
I'm concerned that the bread and butter of products like RS and SSIS is the ability to predict what columns, and what column types to expect from a query, but that introducing dynamic sql will complicate using them.
I'm motivated not to use temp tables or table vars if possible. I'm also somewhat motivated to learn of a solution that works equally well in 2000 and 2005.
I've tried wrapping dynamic calls in a select as shown below but to no avail...
After€¦
declare @sqlString nvarchar(4000)
set @sqlString = 'select * from [' + @dbName + '].[dbo].[activity]'
I€™ve already tried things like€¦.
select a.* from exec sp_executesql @sqlString a
and
select * from exec (@sqlString)

I have searched this forum for how to call a store procedure with
parameter and so far no result has answered my question yet. I have the
following store procedure:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author: <Author,,Name>
-- Create date: <Create Date,,>
-- Description: <Description,,>
-- =============================================
CREATE PROCEDURE sqlSearch
-- Add the parameters for the stored procedure here
@strSearch varchar(250)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
WHERE ([name_nws] LIKE '%" + @strSearch + "%' OR
[title_nws] LIKE '%" + @strSearch + "%'OR [sub_nws] LIKE '%" +
@strSearch + "%' OR [sum_nws] LIKE '%" + @strSearch + "%' OR
[content_nws] LIKE '%" + @strSearch + "%')
END
GO
I got this far in my code on how to call the parameter store procedure.
string strConn = ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString; SqlConnection sqlConn = new SqlConnection(strConn); SqlCommand sqlComm = new SqlCommand(); sqlComm.Connection = sqlConn; sqlComm.CommandType = CommandType.StoredProcedure; sqlComm.CommandText = "sqlSearch"; sqlComm.Parameters.Add("@strSearch", SqlDbType.VarChar); I don't know what do next.
Help is much appreciated.

We have a requirement to call a Web Service method from SSIS where the method accepts a single parameter that is derived from a database recordset and can exceed 4k characters. From the little we know about the Web Service task it is limited to only accepting direct input and variables. Does anyone have any suggestions to overcoming this issue? Any detailed information in possibly calling the Web Service from script or using an object variable would be extremely appreciated.
Thank you in advance for your help.

I need to be able to call a SSIS package with a specific parameter for one of the variables. Basically the package needs to be triggered from an application (.NET, C#) with a specific value.
The package is stored in the SQL Server (in Stored packages).
I have seen the article on dtexec and the SET flag, however we do not want to turn on xp_cmdshell on the SQL server due to the security implications, and that seems to be the only way to call dtexec
I have seen another article that says you can have a job invoke a package then have a specific user granted permission to the job, but that doesn't address how to set the parameter/variable for the package.
There are actually some other steps that technically need to run using the same parameter, so ideally if I could have a stored procedure call the SSIS package, then the subsequent toher stored procedures using the sent in parameter that would be great. I just can't figure out how to do this securely (as xp_cmdshell is not considered secure).
Thanks for any comments.

I'm trying to create a Grid View from a stored procedure call, but whenever I try and test the query within web developer it says I did not supply the input parameter even though I am.I've run the stored procedure from a regular ASP page and it works fine when I pass a parameter. I am new to dotNET and visual web developer, anybody else had any luck with this or know what I'm doing wrong? My connection is fine because when I run a query without the parameter it works fine.Here is the code that is generated from web developer 2008 if that helps any...... <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:IMS3TestConnectionString %>" ProviderName="<%$ ConnectionStrings:IMS3TestConnectionString.ProviderName %>" SelectCommand="usp_getListColumns" SelectCommandType="StoredProcedure"> <SelectParameters> <asp:querystringparameter DefaultValue="0" Name="FormID" QueryStringField="FormID" Type="Int32" /> </SelectParameters> </asp:SqlDataSource>

In t-sql 2012, the followinng sql works fine when I declare @reportID.
IF @reportID <> 0
BEGIN
SELECT 'Students report 1' AS selectRptName, 1 AS rptNumValue
UNION
SELECT 'Students report 2', 2
UNION
[code]...
However when I use the sql above in an ssrs 2012 report, the query does not work since the @reportID parameter can have 0, 1, or up to 200 values.Thus I am thinking of calling the following following function to split out the parameter values:
FUNCTION [dbo].[fn_splitString]
(
@listString VARCHAR(MAX)
)
RETURNS TABLE WITH SCHEMABINDING
AS
RETURN
(
SELECT SUBSTRING(l.listString, sn.Num + 1, CHARINDEX(',', l.listString, sn.Num + 1) - sn.Num - 1) _id
FROM (SELECT ',' + LTRIM(RTRIM(@listString)) + ',' AS listString) l
CROSS JOIN dbo.sequenceNumbers sn
WHERE sn.Num < LEN(l.listString)
AND SUBSTRING(l.listString, sn.Num, 1) = ','
)
GO
how to remove the @reportID <> 0 t-sql above and replace by calling the fn_splitString function?

Is it possible to force a build to fail when a stored procedure in a project calls another stored procedure with one or more required parameters missing. E.g.:
Â
CREATE PROCEDURE [App].[ServiceUser_Save]
@userID int-- Param #0
,@serviceuserID int-- Param #1
,@version int-- Param #2 etc...
And then in a separate stored procedure we have the following
CREATE PROCEDURE [Admin].[CreateMiscellaneousData]
@customerIDint,
@serviceIDint,
@fullURL nvarchar(255),
@apiUserPwd nvarchar(255)
AS
BEGIN
...
EXEC@return_value = [App].[ServiceUser_Save]
@userID = 1,
@serviceuserID = 0, etc...
Note there is no value passed for the @Version parameter.
What I want is the build to fail because of the missing parameter on the call to ServiceUser_Save in the Create_MiscellaneousData stored procedure.
How can I achieve this?

Hi,
i want to modify my DTS to don't have any maintenance to do on it if a Username or password change.
Each DTS will have an ActiveX script to read connections properties in a table that i created and will automatically set each connection in the DTS each time that the DTS Run. So, we will have only to update the table and the DTS will continue working fine.
To update the Connections properties i have no problem, the problem is how can i retrieve the data from my table to get the connection properties, without hardcoding a connection inside my ActiveX script? Because i don't want to have to change each ActiveX script in each DTS if the SQL Server paswword change.
Any idea will be appreciated
Thank

When I run the query below on my DB, it gives the following error:
Server: Msg 8114, Level 16, State 5, Procedure partstlist ...Error converting data type varchar to float.
Only after I replace the " + @d + " section with a float numnber such as 39020.5 does it work fineIt's reported that my temporary table named #tbl doesn't exist within the scope of the environment that the EXEC(UTE) command operates.Someone said that I couldn't combine dynamic SQL and temporary tables or table variables...and that I would have to use a global temp table "##tbl" or a permanent table.
So here I have appearantly a "DYNAMiC SQL & TEMPORARY TABLE" problem. That's sure.
But I don't have much knowledge and experience with SQL tables and have difficulty forming a global temp table "##tbl" or a permanent table.and I have to employ the datetime variable dynamically @d inside the Dynamic SQL string.
So what kind of a code should I use here to properly combine Dynamic SQL string with my dynamic datetime variable? I'd be grateful if you could post your code suggestions so that I can try them on my DB ..

(academic years) to represent if that particular division is active in the current academic year.

Is there a better way to do it, it's not mission critical to make it not use dynamic sql but I would prefer not to.

Hello, I appeal to all to save me from this situation.
I have a WebService in VB.net by IIS and a operation to connect to the SQL server and run a query and others operations. All fine...
But after a certain time only the SQL operations don't respond nothing, the others are OK. So the problem is not in the IIS i think and something between the IIS and the SQL Server.
Can you give me some light about this PLEASEEEE :D ?

If the web service is talking to a SQL Server database and the authentication used is SSPI (Security Support Provider Interface
) / windows authentication, does the ASP.Net user or machine id user
need to be added to the list of allowed ids to the database server? Or
am I misunderstanding the security constraints?
If I run my code through an Nunit test conduit, I can retrieve data,
but If I run it through my webservice it fails authentication.

I'm assuming it's possible to call a web service asynchronously from a SQL CLR function, is this correct or is there a fundamental flaw in calling the asynchronous methods?
I've tried coding a sample and despite creating a new thread, which in turn calls the web service asynchronously and using newthread.join I can never get the webmethodasync_completed sub to be called.

Hi,
I need to expose data in a SQL server 2005 database as a webservices. I have 2 options to choose. I can create an End point in sql or build a webservices in .NET.
So what are de advantages and disadvantages of those 2 approaches ?
Of course they want the webservices secure. I know that authentication is not a problem since we use windows integrated security for the intranet. But what will happen if we move to an extranet or the internet ?
But how do you enable authorization ? and Context security ? Is context security better done in .NET then in SQL ?
Thanks in advance.

CREATE Procedure Ruying_AutoSearch10

@Make varchar(50),
@Model varchar(50) = NULL,
@Condition varchar(20) = NULL,
@Miles float,
@Zipcode varchar(5),

AND dbo.DistanceAssistant(z.Latitude,z.Longitude,r.Latitude,r.Longitude) <= @Miles
ORDER BY @SortExpr
END
ELSE
SELECT -1 As ZIPCode
