    <p>I'm trying to create a linked server in MS SQL Server 2005, pointing to an Intersystem Cache database via ODBC.</p> <p>Below is the query to create the linked server:</p> <pre><code>/****** Object: LinkedServer [CC7] Script Date: 02/22/2011 09:06:39 ******/ EXEC master.dbo.sp_addlinkedserver @server = N'CC7', @srvproduct=N'MSDASQL', @provider=N'MSDASQL', @datasrc=N'CC7', @provstr=N'DRIVER={Intersystems ODBC};Server=CCMSSRVR;Port=1972;Database=CCMS_STAT', @catalog=N'CCMS_STAT' /* For security reasons the linked server remote logins password is changed with ######## */ EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname=N'CC7',@useself=N'False',@locallogin=NULL,@rmtuser=NULL,@rmtpassword=NULL GO EXEC master.dbo.sp_serveroption @server=N'CC7', @optname=N'collation compatible', @optvalue=N'false' GO EXEC master.dbo.sp_serveroption @server=N'CC7', @optname=N'data access', @optvalue=N'true' GO EXEC master.dbo.sp_serveroption @server=N'CC7', @optname=N'dist', @optvalue=N'false' GO EXEC master.dbo.sp_serveroption @server=N'CC7', @optname=N'pub', @optvalue=N'false' GO EXEC master.dbo.sp_serveroption @server=N'CC7', @optname=N'rpc', @optvalue=N'false' GO EXEC master.dbo.sp_serveroption @server=N'CC7', @optname=N'rpc out', @optvalue=N'false' GO EXEC master.dbo.sp_serveroption @server=N'CC7', @optname=N'sub', @optvalue=N'false' GO EXEC master.dbo.sp_serveroption @server=N'CC7', @optname=N'connect timeout', @optvalue=N'0' GO EXEC master.dbo.sp_serveroption @server=N'CC7', @optname=N'collation name', @optvalue=null GO EXEC master.dbo.sp_serveroption @server=N'CC7', @optname=N'lazy schema validation', @optvalue=N'false' GO EXEC master.dbo.sp_serveroption @server=N'CC7', @optname=N'query timeout', @optvalue=N'0' GO EXEC master.dbo.sp_serveroption @server=N'CC7', @optname=N'use remote collation', @optvalue=N'true' </code></pre> <p>I can query the database, for example as below:</p> <pre><code>SELECT * FROM CC7..dbo.iAgentByApplicationStat </code></pre> <p>This works fine.</p> <p>The problem i'm having is when i try and browse the catalog through Microsoft SQL Server Management Studio. Whenever i expand 'Catalogs' under the linked server i get the following error:</p> <pre><code>TITLE: Microsoft SQL Server Management Studio ------------------------------ Failed to retrieve data for this request.

    1. COThis question is for the person who posted the initial Cache link to sql server question. Can you explain how and where you did this link in sql server. I am trying to do a similar thing in order to connect from sql server to a cache db but I don't know where within sql server I do this. Any details on how this is done would be a big help. Thanks

    2. COI use SQL Server Management Studio. There are 2 ways i know of to create a linked server. One is using a query (such as in my original question), the other is using the user interface. In either case, for it to work you must first install the ODBC driver (Intersystems ODBC). To use the user interface to create the linked server connect to it, then expand 'Server Objects', then right-click 'linked servers' then choose 'New Linked Server'.

    3. COI ran into the same issue where I was unable to browse the catalog. While i was unable to get the catalog to populate on-screen. I was able to get column definitions without having to login to cache and look at the class definitions by doing the following: SELECT * INTO tempdb.dbo.iAgentByApplicationStat FROM CC7..dbo.iAgentByApplicationStat where 1=0; I can then expand the iAgentByApplicationStat in tempdb to see the schema definition.

Querying!

 
Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
