The Connection Is Not Found
Mar 2, 2007
Hi. I have a SSIS that is failing and I don't know if it is a logging or dba connection issue. I has this set up:
-A db connection pointing to the data source
-A file connection for the logging
-A package configuration with the db connection and file connection info.
When I run my SSIS in the IDE then I get in the error message this:
Error at packagexxx: The connection "" is not found. This error is thrown by Connections collection when the specified connection element is not found.
Error at packagexxx [Log provider "SSIS log provider for Text files"]: the connection manager "" is not found. A component failed to find the connection manager in the Connections collection.
Do you know how to make it work?

I've got a package which reads a text file into a table and updates another. I set up configurations so that I could import it into the SSIS store on both my dev and live servers. Now, I'm getting this error. I tried removing the configs and am still getting it.
I've been through each step and everything looks okay. Does anyone have any idea (a) what's wrong, (b) how to localise the error or (c) get any additional information? Or do I just have to recreate the package from scratch?

Hi,
I'm having a BIG problem, this is my 3rd day looking for answer !I'm trying to create a custom membership provider with MS SQL database 2005 but not the default ASPNETDB. I've changed the web.config to be as following:<connectionStrings><add name="sqlConn" connectionString="Data Source=.;Integrated Security=True;Initial Catalog=ASPNETDB;"providerName="System.Data.SqlClient" /></connectionStrings> <system.web><trace enabled="true" /><roleManager enabled="true" /><authentication mode="Forms" />
<membership defaultProvider="MySqlProvider"><providers><remove name="AspNetSqlProvider"/><add name="MySqlProvider" connectionStringName="SqlConn" type="System.Web.Security.SqlMembershipProvider" applicationName="/" /></providers></membership>
But when I try to login to the site using the login control the following error occurs:
Server Error in '/etest' Application.
Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

It is clear that this is a prblem with my Machine.Config file - since I've "worked!" on this file for a while. But when I've checked the Machine.config file I've found the LocalSqlServer connection it is talking about! .
I'm lost and I dunno what to do, can anyone help?
Here is the mahine.config in case if you need it:<connectionStrings>

I have been trying to host my website on Go Daddy for about 3 weeks and I have cleared several problems but this one remains. I can get into the ASPNETDB database for doing logins , etc but I cant access my database called "PINEmgt".
To try to understand where the problem is located,I built a very simple application without login controls and put on it one Detailform accessing a single line table "Signin". I continually get the error message I got with my real app :"The connection name 'PINEMgtConnectionString2' was not found in the applications configuration or the connection string is empty. " There is only one connection string in my app -'PINEMgtConnectionString2'. When I run the app locally on my machine it works. After I move everything to Go Daddy, I get the error message and the following dump"
Line 24: </Fields>
Line 25: </aspetailsView>
Line 26: <aspqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStringsINEMgtConnectionString2 %>"
Line 27: InsertCommand="INSERT INTO Signup(first_name, last_name, email, customer_id) VALUES (,,,)"
Line 28: SelectCommand="SELECT * FROM [Signup]"></aspqlDataSource>
This is indeed the code from my single page app.
The dump is:
[InvalidOperationException: The connection name 'PINEMgtConnectionString2' was not found in the applications configuration or the connection string is empty.]
System.Web.Compilation.ConnectionStringsExpressionBuilder.GetConnectionString(String connectionStringName) +3039085

After Googleing, asking Go Daddy for info (which they dont give) , etc for three weeks, I need serious mental help
in the form of a solution of this problem. Your help with the problem or the name of a good mental health professional in eastern N.C. (maybe both) would be appreciated.

Hello,
Does anyone know what this error means and how to resolve it? I get this error when I attempt to run a Data Flow Task. The Data Flow Task has one subcomponent, a Flat File Source. I have set up the connection manager to access the flat file, which is on a local directory. I have tried everything to fix this. What could possibly be the problem??
Thanks

When I try to create an SSIS package with an FTP task, it always fails to compile with the messages:
Error at Package: The connection "" is not found. This error is thrown by Connections collection when the specific connection element is not found.
Error at FTP Task [FTP Task]: Connection manager "" can not be found.
Error at FTP Task: There were errors during task validation.
(Microsoft.DataTransformationServices.VsIntegration)
The item is marked with a circled-X. The tool-tip also agrees: The connection "" is not found.
Using my recreation steps below, I am setting up a connection manager, but it is never found at compile time.
1. Open BIDS, select a new Integration Services project.
2. Drag an FTP task from the toolbox to the Control Flow window.
3. Double-click the FTP task.
4. On the FTP Task Editor window, General page, pull down the FTPConnection property.
5. Select <New Connection...>
6. On the FTP Connection Manager Editor window, enter the servername, port, username and password.
7. Click "Test Connection" to verify connectivity. (It succeeds.)
8. Click OK on the FTP Connection Manager Editor window.
9. Click OK on the FTP Task Editor window.
I'm not using a configuration file or logging provider for this example.
I have also installed SP2 + cumulative update 2.

I'm getting the error
Error: 0xC001000E at : The connection "" is not found.
when executing Control Flow tasks. However the tasks still completes successfully (Execute SQL or DataFlow tasks), and the Control Flow box turns green in the usual fashion.
However if I try to execute all of the Control Flows (using the green Debug arrow), nothing will execute as I get a Package Validation error, with the same error message.
Any ideas why this might be occurring? All of my connection managers look to be set up correctly

We have an application server running Windows Server 2000 with Sp4. When we use the ODBC data sources connection software, it shows the SQL Server 2000 servers in the drop down box, but none of the new 2005 servers. If we enter the 2005 server name and try to connect, we get the 'Specified SQL Server not found' error message. The connection works fine from a newer Windows XP box and remote connections is enabled. My guess is that we need a new ODBC to connect to SQL Server 2005, but I can't find anything that says this.

I added a connection (ADO.NET) object by name testCon in the connection manager - I wanted to programmatically supply the connection string. So I used the "Expressions" property of the connection object and set the connectionstring to one DTS variable. The idea is to supply the connection string value to the variable - so that the connection object uses my connection string.
Then I added a "Backup Database Task" to my package with the name BkpTask. Now whenever I try to set the connection property of BkpTask to the testCon connection object, by typing testCon, it automatically gets cleared. I am not able to set the connection value.
Then after spending several hours I found that this is because I have customized the connection string in testCon. If I don't customize the connection string, I am able to enter the "testCon" value in the connection property of the BkpTask.
Is this an intrinsic issue?

I have a package that uses a for loop to iterate through an unknown amount of excel files and pull their data into a table. However, there will be cases when the file is corrupted or has some sort of problem so that either the transformation will fail or the excel data source will fail with an oledb connection error.
Could anyone suggest a clean way to trap these errors? Specifically, the "Cannot Aquire Connection from Connection Manager", which is the excel connection.
Thanks,

We have a brand new sql 2k server. Its all up to date on service packs(both win2k and SQL).I went in to enterprise manager and added a new db. I can run sprocsand raw sql against the new db just fine from Query Analyzer.When I try to make a dts package that refers to my new db I get thefollowing error:Error desription: deferred prepare could not be completed.Could not locate entry in sysdatabases for database 'mydbname'. Noentry found with that name. Make sure that the name is enteredcorrectly.OK, so I look in sysdatabases and see 'mydbname'. Just in case im anidiot... I actually copied the db name from that table and paste it inmy dts window.My dts package is using an "execute SQL task" to call a stored proc.To be ecxact:USE mydbnameGOEXEC MyProcWhen I click on the parse button, is when I get that error message.I have deleted the db, restarted the server, and recreated the db witha slightly different name. I can replace mydbname with pubs ornorthwind and all is ok. It just doesnt like new db's.Any help would be greatly appreciated.Thanks,Dave

Greetings,
I've found a bug in SQL CE 3.0/3.1. This has been confirmed to be present by other users of this and the microsoft.public newsgroups, both in the Windows CE versions and the desktop x86 versions. I got this response:

And that's where it has ended (after I contacted the team via the blog - no response). Other forum users have suggested that I post here repeatedly until I get a response, so that's what I'm doing. Apologies.

Been trying to get this one but need a little input.
SELECT a.Id,g.LabName......
FROM someTbl a,table g
WHERE a.id = @idAND (b.calLab = g.ID OR g.LabName = ???)
With the above, if b.calLab = 0 then there is no entry in table g.(I didn't develop the table or would have included NONE)
So, how to tell g.LabName to come back as 'None' if b.calLab = 0?
Thanks,

Hello,
I'm working on a function that will return the results in a SELECT statement. But it's not being called properly, and I can't understand why it isn't working. If anyone can help me out I'd greatly appreciate it.
Here's the function code:1 FUNCTION [dbo].[UDFproduct_Search]2 ( 3 @search_string varchar(255)4 )5 RETURNS TABLE 6 AS7 RETURN 8 (9 SELECT product_id10 FROM product11 WHERE product_item_number LIKE '%' + @search_string + '%' OR12 product_part_number LIKE '%' + @search_string + '%' OR13 product_name LIKE '%' + @search_string + '%' OR14 product_commodity LIKE '%' + @search_string + '%'15 )
This SELECT statement returns the expected value:SELECT * FROM UDFproduct_Search('CABINET')
This SELECT statement returns the expected value:1 SELECT * FROM where_used WHERE product_id 2 IN(SELECT product_id FROM product3 WHERE product_item_number LIKE '%' + 'CABINET' + '%' OR4 product_part_number LIKE '%' + 'CABINET' + '%' OR5 product_name LIKE '%' + 'CABINET' + '%' OR6 product_commodity LIKE '%' + 'CABINET' + '%')
This SELECT statement returns errors:SELECT * FROM where_used WHERE product_id IN(UDFproduct_Search('CABINET') Error:'UDFproduct_Search' is not a recognized built-in function name.
I've tried adding dbo to the function call, and in various locations, but I still get the error. Hope someone can point something out I missed.
Thanks.

Call OpenCloseDB(True)
rs = cnn.Execute("SELECT ID FROM PPASA_User WHERE Name='" & UCase(txtUsername.Text) & "' AND Password='" & txtPassword.Text & "'")
If Not rs.BOF And Not rs.EOF Then
Call PopulateUserInfo(rs.Fields(0).Value)

If Not rs.BOF And Not rs.EOF Then
rs.MoveFirst()

'CurrentUser.Name = rs.Fields(1).Value

3)PPASA.vb then creates the connection to the Database. PPASA.vb looks like this.
Module PPASA
Public cnn As New ADODB.Connection
Public Sub OpenCloseDB(ByVal Connect As Boolean)
If Connect = True Then
If cnn.State = 0 Then
cnn.Open("Description=PPASA;DRIVER=SQL Server;SERVER=THE-ONESERVERA;UID=sa;PWD=123;APP=Microsoft Data Access Components;DATABASE=PPASA")
End If
Else
If Connect = False Then
If cnn.State = 1 Then cnn.Close()
End If
End If
End Sub
Public Function CheckSecurity(ByVal Actual As Integer, ByVal Required As Integer) As Boolean
If Actual >= Required Then
CheckSecurity = True
Else
CheckSecurity = False
End If
End Function
End Module
4)After I submit Login.aspx the application boms and gives me the "Specified SQL server not found".
Extra Info:
The Sql server is up and running. I have tested it by connecting with 2 test connection files index.asp and index2 .aspx.
Here are the files. The files also return results from the pubs db.
index.asp
<%
Set conn = Server.CreateObject("ADODB.Connection")
strConn="DRIVER={SQL Server};SERVER=THE-ONESERVERA;UID=sa;PWD=123;DATABASE=pubs"
conn.open strConn
sql = "SELECT * from authors"
set rs = conn.Execute(sql)
if not rs.EOF then
while not rs.EOF
lastname = rs("au_lname")
firstname = rs("au_fname")
response.write "LASTNAME :: " & lastname & " \// FIRSTNAME :: " & firstname & "<br>"
rs.movenext
wend
end if
conn.Close()
Set conn = Nothing
%>
and index2.aspx
<%@ Page aspcompat=true %>
<%
Dim objConn
Dim strConn
Dim objRs
Dim objCmd
Dim objField
strConn="DRIVER={SQL Server};SERVER=THE-ONESERVERA;UID=sa;PWD=123;DATABASE=pubs"
objConn = Server.CreateObject("ADODB.Connection")
objCmd = Server.CreateObject("ADODB.Command")
objRs = Server.CreateObject("ADODB.RecordSet")
objCmd.CommandText = "SELECT * from authors"
objConn.open (strConn)
objCmd.ActiveConnection = objConn
objRs = objCmd.Execute
If Not objRs.EOF then
Do While Not objRs.EOF
response.write ("VALUES :: ")
For Each objField In objRs.Fields
Response.Write (" " & objField.value & " \// ")
Next
response.write ("<br>")
objRs.movenext
Loop
End if
objConn.Close()
%>
There are also the following files in the bin directory.
Interop.ADOR.dll
Interop.MSChart20Lib.dll
Interop.Scripting.dll
PPASA.dll
utCharting.dll
So my question is this, why do I get the error "Specified SQL server not found", when I dont get the error with the test connection files.?
Do I have to do anything with the .dll file in the bin directory, like register them or something?
How does the Login.aspx.vb file call the PPASA.vb file when I see no reference to PPASA.vb
in the Login.aspx.vb file?
I would appreciate any help or suggestions.
Thanks

I am trying to connect to my SQL Server through my ASP.NET webpages. My problem is that, no matter what I do, it always says that the server is not found. I know the IP address of my server, and this IP address works from other computers within my network, just not mine.
I have no idea what it could be. If anyone knows, any help would be greatly appriciated.

I'm attempting a connection to my sql server (running off broadband) from a page I have hosting at my new ISP.. just a standard conn string in .asp..
cn.Open "PROVIDER=SQLOLEDB;DATA SOURCE=24.10.XX.XXX.UID=sa;PWD=mypwd;DATABASE=d_ap p;"
and i get "[Microsoft][ODBC SQL Server Driver][Named Pipes]Specified SQL server not found."
From my older host I have no problems connecting to my server... so I assumed it must be something at my new host, but I'm able to connect to other remote sql servers from my new isp (for example I can connect from my new ISP to the old ISP's SQL server w/o a problem), but for some reason I can't from the new host connect to mine.. is there a setting on mine that needs to change?
newhostwebsvr to oldhostsql works... oldhostwebsvr to mylocalsql works.. newhostwebsvr to mylocalsql doesn't work??
