Get Column Alias From View AND Phisical Attribute
May 27, 2008Hello Everyone,
I am creating a Metadata management application for a business intelligence platform on SQL Server 2005.
For this purpose, I've set out to consolidate all DB-object metadata (Databases, Tables, Columns, Views) into a single repository that business users can browse through. It has been fairly straightforward so far, but I've hit a wall in the views department.
In fairly simple terms, I want to know which physical columns are selected in a view, with the twist of also knowing the columns' alias. This seems to be impossible as far as I can tell, it is easy enough to get both of these independently, but I can't figure out how to connect an alias to an actual column.
(I prefer to use the metadata catalog views to the INFORMATION_SCHEMA as I need to know the object_id's)
Aliases are easy enough to obtain:
select object_id, column_id, name
from sys.columns
where object_id = object_id('SomeViewsName');
As are the 'physical' columns:
SELECT
t.object_id as TABLE_OID,
c.column_id as COLUMN_OID,
c.name
FROM
sys.views v
JOIN sys.sql_dependencies d
ON d.object_id = v.object_id
JOIN .sys.objects t
ON t.object_id = d.referenced_major_id
JOIN sys.columns c
ON c.object_id = d.referenced_major_id
AND c.column_id = d.referenced_minor_id
WHERE
d.class < 2 AND
v.name = 'SomeViewsName';
As I've said before, the problem is joining these two datasets. One of the problems associated with this is that the latter query also returns columns used in JOIN statements, even if they are not projected in the select part of the view definition.
Ultimately I'd like to get this result:
Alias used in View, physical table's object id, physical column's id
Am I missing something?
Thank you very much in advance for your help.
Fetch Metadata From A Column With An Alias In A View
Aug 2, 2007Hi!
I have created a view and one of the columns in the view has an alias assigned to it.
I'm able to read the metadata from INFORMATION_SCHEMA.VIEW_COLUMN_USAGE and also lookup
from which table each column in the view orginated from except for the column that has an alias assigned to it.
Is there any other way to lookup a column that has an alias assigned to it?
Thanks alot!

Can Create Alias Server1DBInstance1 On Server3DBInstance3 And Assign Objects To That Alias
Nov 24, 2015We will be moving 2 different databases (SS2005 & SS2008) to a new SS2014 SQL Server.  Currently our codes looks something like Server1DBInstance1... & Server2DBInstance2... Is it possible to move the objects from these 2 instances to Server3DBInstance3 and then use an alias to reference the objects?  Or does Server3 need to have DBInstance1 & DBIstance2?  Basically, is the alias just for the database or for the instance too?  Can I create an alias "Server1DBInstance1' on Server3DBInstance3 and assign objects to that alias?
View 16 Replies View RelatedDbo Alias
Mar 30, 2000We have an alias for dbo in various code areas, development/test/production. It was easy to tell the DBO alias
on release 6.5 but now on 7.0, the only way I can figure out if the userid is aliased to dbo is to sign on as the userid
and query 'select user_name( )' and if it returns dbo, I have the answer. Is there an easier way to do this by looking in a
system catalog or is there something else I am missing? Thanks in advance. Karen Suenram
DBO ALIAS?
Jul 1, 1999In 6.5 you could alias someone as dbo, thus preventing an ownership chain break. In 7.0 there are roles, one of which is db_owner. I gave a user db_owner role, and they created a table. But no one else can see it? And he is listed as the owner in EM. How do I more effectivly mimic the dbo alias available in 6.5?

Jun 2, 2008Hi All,
I've just installed an active/active sql cluster. Both are named instance hence if i need to connect to it, I need to use NODE1SQLINST1 and NODE2SQLINST2. Is there a way to just use NODE1 or any other single name to connect to the sql instance? I was looking at Alias but I can't get it working. Anyone has any ideas or suggestion for me? Reason why i want to do this is in an odbc connection, instead of using NODE1SQLINST1, I can use NODE1.
Thanks

ROLES Vs Alias
Feb 16, 1999I am just getting started with SQL Sever 7.0, most things are must easier and simpler.
I do have one mind set problem
With SQL 6.5 I created a logon(JAWS) , aliased the developers to the logon(JAWS)
and all the tables and other objects were owned by ((JAWS). The developers would then grant
access to the tables. And the users would open JAWS.tablename.
In the SQL 7.0 test are I take an NT group that have the devlopers in them and allow SQL SErver
logon for that group. Then I allow the group access to the database and give the group
database roles of db_owner, db_ddladmin, db_datareader and db_datawriter.
The developers can create objects but the objects are not owned by the role but are
owned by the indivudual NT accounts that are in the NT group.
Any hint of what to change to have the ownership show up as the NT group??

Column Alias

I was wondering if there is a way that you can set the alias name of a column to a value that resides in another table instead of the alias being a static value that you type in.

Database Alias
Sep 27, 2006Is there any way in SQLServer (2000) to setup an alias to another SQLServer database?
What I want/need to do is this:
.i have a database for each project but many of the tables schemas/triggers/stored procedures/etc. are common so what I want to do is run one set scripts. I want to essentially set up a project structure so that all specific app databases also include some core stuff.
.for example, consider a Users table (simple example). For two applications we have exactly the same users structure, sprocs, triggers, etc. but we have physically different data. I just want to run the same ddl.
.but the users table has a log associated with it in an associated log database. The trigger (and some historical queries) refer to the explicit log database (App1Log.Users, for example).
.what i'm figuring is that if i could set up an alias to the log database and have the sql code refer to that I'd be able to reuse all the code very neatly:
set logDBAlias = 'App1Log'
insert into logDBAlias.Users etc....
.trouble is I cannot figure out how to alias the log database!
Any ideas?
Thank you.

Server Alias
May 13, 2004how to add a alias to a server?
I have gone through BOL where it says it can be done thru right click agent -->> connections and configure alias.
i want to know if i configure a alias to a server from a client is it valid for other connections also?
meaning there are two database servers A and B
i add alias to server A by using client network utilities on server B,
then is this alias available if i try to connect to the server A thro some other server c?
hope this is not that confusing as it sounds. ;)

TNS Alias Name Changed

I used SSIS to transfer data from Oracle database to SQL Server 2005 (with Microsoft OLE DB Provider for Oracle). It worked fine with the TNS alias name said oracle1. Then I changed the TNS alias name to oracle2. I could connect to Oracle database with oracle2 using Oracle's tool. But SSIS could not find (or solve) oracle2, if I changed the name back to oracle1 in SSIS, then SSIS worked.
Any idea?

How To Use Alias In SQL Server?

Is there any way to refer to an Alias in a select statement? For example, if I create an expression that sums to fields together and give it the alias TOTAL, and then in another field I want to create and other expresssion that multiplies a field by TOTAL, what is the syntax?
In MS Access the Alias name is surrounded by brackets, but I can't seem to find a way to do this with SQL Server.
Thanks
