I want to connect my OBIEE to a table which is supposed to be within BI.
So what I do is examine the Connection properties inside of SQL Developer :
And I see that the hostname is "ed10-scan" - is this some special notation for SQL Developer, or some kind of metadata? I was expecting it say something something like "ed1001" or "ed2002" .
A "hostname" is the logical name of a - in this case - server.
https://en.wikipedia.org/wiki/Hostname
It can literally be anything one wants. if you "need a hostname with a number like..." then give your server a new name or at least a new alias over which it can be reached on your network.

For a query which looks something like
select * from cus_query.ca_activity_vw#drifter
I imagine cus_query is the schema and the view's name is ca_activity_vw. But what is drifter ?
I quote the Oracle documentation:
If the identifier names an object on a remote database, you must reference it with its remote name. The syntax is:
simple_identifier_name#link_to_remote_database
If the identifier is declared in a PL/SQL unit on a remote database, you must reference it with its qualified remote name. The syntax is:
unit_name.simple_identifier_name#link_to_remote_database
From this page : http://docs.oracle.com/cd/E11882_01/appdev.112/e25519/fundamentals.htm#LNPLS99945
drifter is a so-called database link - it allows to transparently query tables that reside on a different database (usually Oracle, but possibly some other RDBMS, e.g. via Database gateway).
To see the definition for the database link, you can use this query (this requires DBA privileges):
select * from dba_db_links
I use the denisenkom/go-mssqldb package for connecting to SQL server in go but I don't know how to write the connecting code,
what are the arguments of this method : sql.Open() for example when we say :
db, err := sql.Open("mysql", "user:password#/database")
what do "mysql" and "user:password#/database" refer to?
and in which part of the program we should tell the name of the database which we want to use in the program? I mean in which part of the code we introduce the name of the database we want to use?
"mssql" is the protocol/driver/database type you are connecting to. "user:password#/database" is the connection string. See this example for the components of this String.
Your application typically knows the database it wants to connect. Or at last when the user logs in.
Can someone point me to the relevant BOL info for this (odd to me) behavior?
I had to join the prod & staging copies of the same table (same db name, diff servers), for a quick query. So I simply needed a fully-qualified join.
This one errors:
SELECT top 10 *
FROM [172.26.196.105\Staging].[DbName].[dbo].[TableName]
This one works:
SELECT top 10 *
FROM [USCASQL01\STAGING].[DbName].[dbo].[TableName]
Edit: clarification ... obviously not a join, these selects were simply me assembling the fully qualified name of my staging db/table. This is not a linked server, but the one I'm connected to.
These, of course, refer to the same instance. I used the IP address\InstanceName since that is what displays in my Object Explorer, it returned an error - "Could not find server 'IP address\InstanceName' in sys.servers." True enough, sys.servers stores the computerName\InstanceName, which works.
Why would one work and not the other? IOW, Why can't it resolve the IP/Instance name in TSQL when it resolves it just fine in the Object Explorer? BTW, we frequently are storing IP's in sys.servers, this one just happened not to be.
Also, I recall from SQL Server7 (way back in the day), a utility that would allow you to create friendly-name aliases for ip's. Can't find it now, does it still exist?
TIA
This is because the first part of a four part qualified name is a reference to a linked server by name, not by an IP or network name. So, if you don't have the linked server set up, then you get the error you encountered.
For adding linked servers, you want to be looking at sp_addlinkedserver.
This is the BOL Page that describes how the four part names work.
I have a production server and I standardized the names of all the DBs on the server to
projectName.whatever
The problem is I have one database named
projectName_logging
I want to rename it to
projectName.Logging
(OCD a bit?)
The problem is there are connection strings that all say projectName_logging. Is there a way to say if a connection is projectName_logging to automatically redirect it to a catalog now named projectName.logging ?
As requested by the OP, I'm making my comment an answer.
Sounds like what you really want is a synonym for a database name, which doesn't exist, but you can vote for the feature here.
Hi I am having a problem, accessing a remote index server catalog. The name of the server has - in it, so i put the index catalog name as:
i.e num.num.num.num\name of catalog
or an-example-server
I get the following error when using an ole data connection to pull results from the index:
"Format of the initialization string does not conform to specification starting at index 39"
I tried putting single quotes and &qoute; with no luck - anyone have idea?
PS. This Microsoft Index Server Question!
I found the answer or certainly a solution. By adding an A record on the domain (with a friendly name), I managed to talk to the remote catalog without any problems. :)
