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 data
Note how the "speed" alias is used in the definition of "acceleration" alias but this doesn't work.

Is there any way to group variables present in a select statement.
My code:
SELECT @var1=something, @var2=something_else
FROM ...
GROUP BY @var1
I wanted to group by 'something' hence I used a variable to assign it to. But I'm unable to group it.
Any thoughts?
Thanks,

Hi all,
The requirement is to have a table say 'child_table', with an Identity column to refer another column from a table say 'Parent_table'..
i cannot implement this constraint, it throws the error when i execute the below Alter query,
ALTER TABLE child_table ADD CONSTRAINT fk_1_ct FOREIGN KEY (child_id)
REFERENCES parent_table (parent_id) ON DELETE CASCADE
the error thrown is :
Failed to execute alter table query: 'ALTER TABLE child_table ADD CONSTRAINT
fk_1_ct FOREIGN KEY (child_id) REFERENCES parent_table (parent_id) ON DELETE
CASCADE '. Message: java.sql.SQLException: Cascading foreign key 'fk_1_ct' cannot be
created where the referencing column 'child_table.child_id' is an identity column.
any workarounds for this ?
Hi,
I need to create a table (Named as C) with a foreignkey column. That column should references with a primarykey column in table A and a primarykey column in table B. Is this possible?
Thanks in advance.

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.

Hi,
I’m working with a really old design migrated to SQL 2005, in which I basically have two tables…
Table 1 contains all the “proper” data, and has columns called: col_1, col_2, col_3
Table 1’s data is something like:
col_1, col_2, col_3
Jack,jack@yahoo.ca,Toronto
Jill,jill@hotmail.com,Montreal
Table 2 contains meta-data for Table 1, specifically, it has two columns: column, meta-data
Table 2’s data is something like:
column,metadata
col_1,name
col_2,email
col_3,city
(Hopefully, my description of the design makes sense….basically; Table 2’s data describes what’s in each column of Table 1).
So, the question, if I want to write a ‘SELECT’ on Table 1, how can I use the data in Table 2 as aliases (or column) headers.
I’m currently going down the path of building dynamic SQL statements in T-SQL….but before I get too far, wanted to vet this idea here (it’s always been a fantastic resource for me)
Thanks in advance!

I posted a thread in the Getting Started forum about how to make a counter for maximum tickets : http://forums.asp.net/t/1215258.aspx
but maybe this is a more appropriate forum for this subject.
In a school project, we are making a website for a fictional concert/festival (using Visual Studio 2005, C#). On that site users can register and order tickets.
We have access to an SQL-database, by the way, where we can create tables etc.
We want the maximum amount of tickets to be 10000 per day. The festival is supposed to last from friday to sunday.
What would be the best way to do this programatically? The counter should maybe be in an own database table?

How can I do that (alias..., description ?

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'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.

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

I have a copy of class schedules with only students that are taking half of a full year class in a separate table. The table lists the term that the students are taking so I joined that table to the actual class schedule table via the code below. The values are 1 & 2 and if it's null (not taking half of a full year class) it's a 9. So now I only need 9s and 2s to bell pulled from the script below. How do I go about doing that since HLF_Term is not a real column?

,STUSCHEDULE.[School_Number]
,STUSCHEDULE.[Student_ID]

Hi Guys,
I have a program that connects to SQLServer 2000 through ADO connection.
the program executes the following query:
SELECT ax.AccNo,
(SELECT Accounts.ProductCode FROM Accounts WHERE h.ID=Accounts.ID) As Product
FROM dbo.History h LEFT OUTER JOIN dbo.AccXRef ax ON h.ID= ax.ID LEFT OUTER JOIN dbo.States ON h.[HistoryItemsub-Type] = dbo.States.Type LEFT OUTER JOIN dbo.CustXRef cx ON h.CustomerNo = cx.CustomerNo
WHERE HistoryItemDate <= getdate() ORDER BY HistoryItemDate ASC
This query works in th program and in Query Analyer on my machine.
However, On a different Machine (and different SQLServer) the query works in Query Analyser but does not work in the program, the following exception is thrown:
The column prefix 'h' does not match with a table name or alias name used in the query
Any help is greatly appreciated..

insert into #temp values('john',1000)
insert into #temp values('Mike',500)
insert into #temp values('Abhas',200)
select name,sale as sale from #temp

so my output would be as
name Sales2014
john 1000
Mike 5000
Abhas 2000
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.
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!
