Getting Meta-data For Linked Servers
Oct 25, 2006
My customer has a .NET application that reads meta data from SQL Server, Oracle, DB2, and several propritary databases. Because each DBMS stores the meta data using various techniques, they have written custom code for each DBMS. They are working on a generic ODBC/OLEDB suppport, but in the interim I was trying to use SQL Server to link to an Access database. The Access linked server works fine for queries in Query Analyzer, but I would like to be able to programatically read the metadata for an Access DB (tables, columns, types, etc) via the linked server. SQL Server's usual mechanism for storing meta-data in the Master database aparently is not used for Linked Servers.
Does SQL Server expose Linked Server meta data?
How would one retrieve this meta data if it is exposed?
Thanks,
Ben

Hello to all,
my problem is about the slow execution of a query.
I have two database located in two different servers. The servers are linked with the linked server connection made with the enterprice manager.
The databases structure is the same and I copy some data from a database to the other with the following query:
INSERT INTO DATASERVER.RESULTS.dbo.Tab_Tests SELECT * FROM LINESERVER.WIP.dbo.Tab_Tests WHERE ID_Result = '{76271FC1-9470-4EF7-A403-000CF75C2215}' OR ID_Result = '{08C8EEB9-CD22-4CF9-8269-8C1CC58C752B}' OR ID_Result = '{B7B7EED1-36E4-48FA-9636-ABBE62AAE04D}' OR ID_Result = '{8F7BA69E-D2CE-4EB2-BBC4-AFFA165CE0CE}' OR ID_Result = '{273CB805-945F-4EFA-AE20-BC4E0898A19F}'
Everything works till the database grows up more than 400 MB.
Also if I select one result, that consist of some records, the query is very slow and the CPU is working over the 75 %.
I ask you if my working way is corret or if you have some solution or some explanation for me.
Thank you

Hi all.
I need your help.
I create a linked server on SQL 2005 server using IBMDA400 as provider.
I create a VBscript to update some data on DB2, and issue begin trans and commit trans. Kindly refer to below code.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Set oKCDat = CreateObject("KCDAT.kcdatapi")
Set objConnection = oKCDat.OpenConnection_SQL(strDataSource,strDB, strUserID, strPassword)
Set rs = CreateObject("ADODB.Recordset")
strName = "TEST1"
strTemp1 = "2"
strTemp2 = "3"
intTemp1 = 199
strSQLStatement = "SELECT * FROM QS36F.TEST WHERE PRACNM = ''" & strName & "''"
strUpdSQL = "TEST1 = '" & strTemp1 & "', TEST2 = '" & strTemp2 & "', TEST3 = " & intTemp1
strSQL = "UPDATE OPENQUERY(TESTDB2," & "'" & strSQLStatement & "')" & " SET " & strUpdSQL & ";"
objConnection.BeginTrans
objConnection.Execute(strSQL)
objConnection.CommitTrans
objConnection.Close
Set rs = Nothing
Set oKCDat = Nothing
Set objConnection = Nothing
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------
When i run above script, it prompt me an error message;
"Microsoft OLE DB Provider for SQL Server
The requested operation could not be performed because OLE DB provider "IBMDA400" for linked server "TESTDB2" does not support the required transaction interface."
If i run it without "begintrans" and "committrans", it update the data successfully.
Does anyone know about it?
Highly appreciated for above matters.
Regards

I have a report my business users need from from two data sources, which are on two different servers (both are oracle DBs). I have a common Primary key between both. I've read through a ton of posts and it looks like there is no way to join the data using Datasets, that you need to do something called Linked Servers.
but what I couldn't find is where do I go to create a Linked Server and how. I'm new to SS, so I need help and details.
the more step by step details the better.
Thanks

I have multiple web databases for storefront orders as linked servers on SQL Server 2008 R2. I need to organize the data for these orders into a structure that can be imported into my ERP application db frequently either on demand or periodically during the day. We are essentially trying to make the manual order entry process automated. My thought was to get the data into views that resemble the schema of the order table in my application db and then schedule a stored procedure with sql jobs or a load routine from within the ERP application that would insert data from the view into the order table.

Hi all, i got this error:
[DTS.Pipeline] Error: "component "Excel Source" (1)" failed validation and returned validation status "VS_NEEDSNEWMETADATA".
and also this:
[Excel Source [1]] Warning: The external metadata column collection is out of synchronization with the data source columns. The column "Fiscal Week" needs to be updated in the external metadata column collection. The column "Fiscal Year" needs to be updated in the external metadata column collection. The column "1st level" needs to be added to the external metadata column collection. The column "2nd level" needs to be added to the external metadata column collection. The column "3rd level" needs to be added to the external metadata column collection. The "external metadata column "1st Level" (16745)" needs to be removed from the external metadata column collection. The "external metadata column "3rd Level" (16609)" needs to be removed from the external metadata column collection. The "external metadata column "2nd Level" (16272)" needs to be removed from the external metadata column collection.
I tried going data flow->excel connection->advanced editor for excel source-> input and output properties and tried to refresh the columns affected.
It seems that somehow the 3 columns are not read in from the source file?
ans alslo fiscal year, fiscal week is not set up up properly in my data destination?
anyone faced such errors before?
Thanks

Hi Guys,
I have a DataBase in which I have several Tables.
What I want is an SP or Query which takes as its parameter the "tablename".
The Output Should be a having three fields only.
Field name, DataType Of the Field, Length of the DataType.
For Example
Suppose the StoredProcedure Name is "SP_GetTables"
if i have a table named "tbl_Users" with fields
UserName varchar(50)
UserPass varchar(20)
UserAge int
UserStatus bit
In my program side if I pass the parameter as "tbl_Users" to the StoredProcedure SP_Users,
I should get the O/P as
Field Name DataType Length
UserName varchar 50
UserPass varchar 20
UserAge int
UserStatus bit
Regards,
Naveen.

Okay... We have a SQL2K database that has about 500 tables or so. It is normalized to a reasonable level and enforces all relationships with PK/FKs, not triggers. Hence, for a database-minded person it is fairly easy to read (as easy as a 500+ table database can be!).
Our users need adhoc query capabilities. Our report writer is simply overwhelmed. He doesn't need to be spending time writing a report that is intended to be run once.
I expect the best alternative would be to use some sort of adhoc reporting tool that is based off meta data. We (the DBAs) could be responsible for maintaining the meta data and STILL have a manhour savings over developing all these reports.
Here's the catch... We are on a TIGHT budget (aerospace industry is still reeling a bit). Is anyone using a product or aware of a product that might be just the ticket for us? We have been investigating a product by LogiXML called LGX AdHoc (http://www.logixml.com/products/AdHoc/adhoc.htm). Looks promising. Anyone use or familar with it?

Hi
I am running a couple of sql 2000 SP3a servers with merge and snapshot replication. One server acting as publisher and distributor and the rest subscribers. On one of the server I have got the error below and have tried most of the suggestions by msdn. This server has not crashed ever before or any hardware problems. It has been running for a couple of months and no problems. This has not happened no any of the other servers. Any suggestions would be greatly appreciated as the only resolution I have left is to bring up a new instance, setup replication and see if this would resolve the issue. Stopping and starting of agents don't work.

We are running SQL Server 2000, SP4. I recently noticed that my DTS packages were missing from the local server. Since I had saved them as Structure Storage Files, I imported them back into DTS Local Packages. That was yesterday. Today I opened the Meta Data browser to see what was in it. (We don't use Meta Data Services.) It displayed a message:"An error occurred while trying to access the database information. The msdb database could not be opened." These (restore of DTS pkgs and Meta Data error) may not be related, but I need to know why I am getting this error, because I am about to upgrade to SQL Server 2005 for Workgroups.
1. Does anyone know what causes this error message?
2. Are local DTS packages stored in the MSDB database?

I am running SQL Server 2000 SP3 and I am trying to save a DTS package into Meta Data Services and I am receiving the following "Package Error"
Error Source: Microsoft Data Transformation Services (DTS) Package
Error Description: General Error -2147217355 (80041035).
I have searched for this error and I cannot find anything related to it. Also, I saw some of the comments about right clicking "Data Transformation Services" and checking the box for allow save to Meta Data Services, however, I do not see that checkbox to allow for this. Has anyone else had this problem and resolved it? I'm beginning to get very frustrated with it.

I have been given a request by a business analyst to update the text 'old' to 'new' within the column names / measure names and associated calculations within a PowerPivot model. There are hundred of columns / measures / calculations, etc. which need to be renamed.
Is there any way of updating these changes to the model other than making these changes manually or is there some way of doing the following type of operation in PowerPivot; -
UPDATE tblColumnNames SET Column_name, etc REPLACE ('old','new', all columns),('old','new', all measures),('old','new', all calculations)

Hello anyone / everyone,
If you are having trouble accessing Meta Data Services on W2k3 and SQL 2000 and get the error that the "msdb database could not be opened" I found that hot fix 912812 on the operating system is the culprit. Remove it and Meta Data goes back to working, although I am being asked to approve the ActiveX control every time the page refreshes.
Hope this helps somebody, to took me long enough to track it down.
If anyone has a resolution to the ActiveX question I'd love to know the answer.
Thank you,
Uncle Davy

Hi,
I'm using SQL Server 7.0 SP1.
I have a DTS package that requires me to link 2 servers
and query both in order to get my set of records that I
want to Transform. My query runs fine in QA. I copy and
paste it into the SQL Query window of the transformation.
I click Preview and all that happens is a quick flicker of
the DTS window. When I go to Transformations, there are
no source columns.
Here is a copy of my code that I'm trying to use:
-------------------------------------------------------
