Hi!
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!

Have many views based on legacy tables that have different table and column names. Want to create a table that shows view table / column and underlying table column, e.g.
CREATE VIEW [dbo].[Branch]
AS
SELECT
divbra_id BranchID,
cmpny_id CompanyID,
divbra_cde BranchCode,
divbra_nme BranchName
FROM MyDatabase.dbo.divbranc
GO
is an existing view. I want to pull out the following metadata:
divbranc divbra_id Branch BranchID
divbranc cmpny_id Branch CompanyID
divbranc divbra_cde Branch BranchCode
divbranc divbra_nme Branch BranchName
Is there anyway to get this from SQL metadata without actually parsing the view SELECT statement in code?
Hello 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.

I have added alias datatypes using sp_addtype and would like to view the properties defined in it.
please let me knowhow to view the properties of them and also is there a way to list all alias datatypes existing in the current database along with their properties.
I created a view with a simple join query
there are 2 rows with orderid as null, i am unable to fetch the details when i give WHERE Condition as
"select orderid from joins where orderid=NULL"
Query :
create view joins as
select A.customerid,A.Companyname,A.Contactname,A.City,B.OrderId from Customers A
left join orders B
on A.Customerid=B.Customerid
Is there a way to display a column alias as part of the result set column labels?

Using SQL Server 2000. How can I refer to one alias in another column?E.g., (this a contrived example but you get the idea)SELECT time, distance, (distance / time) AS speed, (speed / time) AS acceleration FROM dataNote how the speed alias is used in the definition of acceleration alias but this doesn't seem to work.

SQL table and column metadata
Is there a way to add or update the column or table (using the extended properties) description metadata via T-SQL (from within a stored procedure) or via a program (such as VB.NET using ADO)?
These metadata properties are available via the SSMS interface:
Columns via the Column Properties/Table Designer/Description
Tables via the Table Properties/Extended Properties/[Extended Property Name]
Thanks in advance,
Mark
In SQLServer I can't change my SQL column name.
But I need to see another field name in query tool (Excel)
How can I do that (alias..., description ?
Thanks
Hello everyone.
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.
If anyone has any ideas on ho i can accomplish this i would greatly appreciate it.
I do an insert of the xml into the table and that works fine, but how do I split the tags to different tables. I have tried SSIS and a XML Source to an OLEDB Source, but since the xml file contains different groups that do not work.
The xml is created by Infopath and it seems like the groups are created if the components belongs to different sections.
Table1
id int,
xmltag xml
I am starting to be desperate, I really need some help solving this one way or another.
Hi All,
I have two tables.
Table A contains a unique column of some Keys.
Table B contains Key column,Value column and Entry_Time column.
Now I need the most recently entered value for each of the Keys in table A using table B.
I dont need any repeatation of Keys in my result.
Please help me out.I am using DB2.
I keep getting the following error in SSIS. Also, I don't get the error on every server the package is run on, but less than 5 (the package is run on over 100).
"The external metadata column collection is out of synchronization with the data source columns. The column "Timestamp" needs to be added to the external metadata column collection"
Please tell me where I need to remove Timestamp from. Thanks

I'm using SQL Server 2005 and are having some troubble with sorting a paged result set. I'm using the OVER Clause to achieve the sorting and paging and have the following query:1 WITH ProjectList AS
2 (
3 SELECT
4 Id,
5 Name,
6 Created,
7 (SELECT COUNT(*) FROM UserProjects WHERE ProjectId = p.Id) AS NumberOfUsers,
8 ROW_NUMBER() OVER (ORDER BY Id) AS 'RowNumber'
9 FROM Projects p
10 )
11 SELECT *
12 FROM ProjectList
13 WHERE RowNumber BETWEEN 50 AND 60;
This works fine, and give me the results i want. The problem occurs when I want to sort by "NumberOfUsers" which is the results of a sub query.When i say "ORDER BY NumberOfUsers" instead of Id on line 8, I get the following error:
Msg 207, Level 16, State 1, Line 10Invalid column name 'NumberOfUsers'.
I read this in the documentation:
When used in the context of a ranking window function, <ORDER BY Clause> can only refer to columns made available by the FROM clause. An integer cannot be specified to represent the position of the name or alias of a column in the select list. <ORDER BY Clause> cannot be used with aggregate window functions.
So this means that what I'm trying to do is not possible. How can I then sort by NumberOfUsers? Is there any other way to achieve this
Hi All,
I am currently transferring my Access application to SQL Server. Access allows you to declare and use aliases in the query at the same time.
e.g.
Select field1 as Alias1, field2 as Alias2, Alias1 & " " & Alias2 as Alias3 from table1;
In Access the above query will execute perfectly, no problem. However in SQL Server, if you try to run the same query it will give an error "Invalid column name Alias1" meaning that SQL Server is searching for Alias1 as a field in the table, not as an alias from the query.
My question is does SQL Server have a facility to declare and use alias directly as in Access and if no, is there a workaround?
Thanks for your time.

Hi,
I have a question.
select name, count, 1 Aa c1, 2 as c2, c1+c2 As total
from table1
From this example, the program will give out error message,
c1, and c2 are invalid columns.
In MS Access, it works. But, SQL query Analayer doesn't work this statement.
So, does query analayzer handle this case?
Thanks.
I have a web application where I would like to return a dynamic column name using aliasing. below is an example:
select hours as 'Fri<BR>' + cast(Day(getDate()) as varchar(2)) from todayshours
I get an error trying to do concatenation as part of the alais. Any ideas?

Is there a way to use a column alias in an another calculation within thesame query? Since I am using some long and complex logic to compute total1and total2, I don't want to repeat the same logic to compute the ratio ofthose two columns. I know that I can do a nested query, but that seems toolengthy as well since I actually have many, many columns.selecttotal1 = sum(case(long complex logic)),total2 = sum(case(another long complex logic)),ratio = total1/total2

Hi,
I am using SQL Server 2005 Mobile Edition & Merge Replication
in this I want to insert a record into table,
in that table I have taken UserID coloumn as auto incrementing Identity type.
In a book I read that,
If you are using an Identity column, you must find the next available number and reseed before an insert can be successful. You will also have to set up ranged identity columns on the published database to prevent errors when the new data is merged.
Now I want to ask here that, how should I ressed that value before inserting?????
any help in a form of CODe will be appriciated.....
thanks in advance...
Hi all!
My problem I've been struggling with is the following. I have a set of text files (around 70), each with different column numbers and types. I define Flat File Connection Managers for each of them where I can nicely rename, set data types and omit certain columns. I do this once and this will be the basis for the rest of the data process (would be nice programmatically too actually).
I would like to pump each of these text files into SQL Server tables using CREATE TABLE and BULK INSERT (because do it one-by-one is really a pain). The question is:
is there a way to obtain column information (Script Task) from a Connection Manager so I can run CREATE TABLE-s? I just need the names, data type for each nothing fancy...
(I bumped into interfaces like IDTSConnectionManagerFlatFileColumns90, which I cannot handle from the Script Task.)
Any help appreciated!
I am having one store procedure which use to load data from flat file to staging table dynamically.everything is working fine. staging_temp table have single column.all the data stored in that single column below is the sample row.
AB¯ALBERTA ¯93¯AI
AI¯ALBERTA INDIRECT ¯94¯AI
AL¯ALABAMA ¯30¯
after the staging_temp data gets inserted into main table.my probelm is to handle such a file where number of columns are more than the actual table.if you see the sample rows there are 4 column separated by "¯".but actual I am having only 3 columns in my main table.so how can I get only first 3 column from the satging_temp table.output should be like below.
AB¯ALBERTA ¯93
AI¯ALBERTA INDIRECT ¯94

Hi,
I have an Excel file source. I keep getting this error when running the package:
"The external metadata column collection is out of synchronization with the data source columns. The column "x" needs to be updated in the external metadata column collection."
When I get this error with regular flat files, it's because I've changed the data type of a given column in the flat file connection manager. And I resolve it simply by double-clicking on the flat file source task, and viola - it corrects it for me.
How do I correct this with an Excel file? Help.
Thanks
What I need to do is to create 3 columns with 3 different aliases from the same table that will return all the values during the following conditions:
when pricelist = 1
when pricelist = 2
when pricelist = 3
pricelist
--------
1
2
3
Price
--------
912 -- (linked with 1)
234 -- (linked with 3)
56 -- (linked with 2)
3245 -- (linked with 3)
234 -- (linked with 1)
65 -- (linked with 2)
these 2 columns are in the same table^^
so what i want my query to generate is:
Price1
--------
912
234
Price2
--------
56
65
Price3
--------
234
3245
Any help is apprecieated, thanks
if the above does not make sense to you maybe this will:
"can you make 3 aliases of the same column and only display the rows inside each column where pricelist = 1 for the 1st alias... where price = 2 for the 2nd alias...where pricelist = 3 for the 3rd alias"
