SELECT Column Aliases: Refer To Alias In Another Column?
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 seem to work.

How To Refer A Column When The Referencing Column Is An Identity Column
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 '.

Is It Possible To Re-reference A Column Alias From A Select Clause In Another Column Of The Same Select Clause?
Example, suppose you have these 2 tables(NOTE: My example is totally different, but I'm simply trying to setupthe a simpler version, so excuse the bad design; not the point here)CarsSold {CarsSoldID int (primary key)MonthID intDealershipID intNumberCarsSold int}Dealership {DealershipID int, (primary key)SalesTax decimal}so you may have many delearships selling cars the same month, and youwanted a report to sum up totals of all dealerships per month.select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',sum(cs.NumberCarsSold) * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDMy question is, is there a way to achieve something like this:select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',TotalCarsSoldInMonth * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDNotice the only difference is the 3rd column in the select. Myparticular query is performing some crazy math and the only way I knowof how to get it to work is to copy and past the logic which isgetting out way out of hand...Thanks,Dave

Using Data As Column Aliases
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!

ADO MD Column Names / Aliases
I'm working on an application to display sales data using sql server 2000 reporting services. The data is in an MS Analysis Services cube, so I'm using MDX queries in the data set. The queries all have a similar format of the form: SELECT {[Measures].Members} ON COLUMNS, { MyDimension.members} ON ROWS FROM MyCube where the items in the COLUMNS clause are allways the same and MyDimension might be SalesBranch, ProductCategory, etc. When Reporting services works out the fields for the returned data set it appears to be flattening out the MyDimension structure and using the dimension level names for field names. eg <Fields> <Field Name="Manufacturer"> <DataField>[Manufacturer_Model].[Manu].[MEMBER_CAPTION]</DataField> <rd:TypeName>System.String</rd:TypeName> </Field> <Field Name="Measures_Oe_Id"> <DataField>[Measures].[Oe Id]</DataField> <rd:TypeName>System.Object</rd:TypeName> </Field> <Field Name="Measures_Oe_Realval_A"> <DataField>[Measures].[Oe Realval A]</DataField> <rd:TypeName>System.Object</rd:TypeName> </Field> </Fields> In the report layout I can select these fields and display them as expected. However the drawback is that since dimension level names are encoded into report field names I have to have a separate report for each dimension I want to put on the ROWS. ie one .RDL file for SalesBranch, one for ProductCategory etc. If this was SQL it would not be a problem because in the SQL SELECT statement the column names could be fixed using "SELECT colname AS othercolname ", but, being new to MDX, I can't find how to do this. Does anyone know how to achieve this in MDX / ADO MD ? ie how to give an MDX column an alias Thanks Steve

Counter For Max Tickets - Refer To A Database Table Row/column Etc
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?

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.

Order By Column Alias
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

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

Column Alias In Views
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. Regards: Prathmesh

Get Column Alias From View AND Phisical Attribute
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.

Custom Column Alias (Reporting Services 2005) When Designing Reports From MDX Queries
Hi All, In T-SQL, it is easy to to provide a column alias example "CustomerName" AS Name, "CustomerPhone" AS Phone, etc. When we are developing SSRS 2005 reports using MDX , when the columns are a result of cross joins on ROWS , I don't know a way to provide a column alias within the MDX query. If anybody knows then please share. But I have found a easy solution. 1) Switch to the 'Layout' tab of the report designer 2) Click on View->Datasets (or press Ctrl+Alt+D) to bring the datasets. 3) Expand the datasets, highlight the dataset where you want to change the column name. 4)Right Click the column name you want to 'rename', then click on 'Edit' 5)Under 'Edit Field' change the 'Name' to the name you want to.(Example : your previous column name was 'CustomerPhone' , change it to 'Phone' 6)Once you have changed the column name, the fields with (=Fields!CustomerPhone.value) has to be changed to (=Fields!Phone.value).So Drag and Drop the fields again 7) Run the report..Enjoy.... You may need to change the column name because of certain business requirements. I had a requirement where an XML parser requires the field names to follow certain naming conventions. Another way to chnage the 'column' name is to change the 'Name' property of the column. Thanks Bidyut

Code Block CREATE TABLE [Liga] ( [cod_cliente] [varchar] (50) COLLATE Latin1_General_CI_AS NULL , [tronco] [int] NULL , [nrtelefone] [varchar] (50) COLLATE Latin1_General_CI_AS NULL ) ON [PRIMARY] GO 1111 10 89543964 1111 9 32659841 1111 8 32569874 1111 7 25469874 CREATE TABLE [Lista] ( [cod_cliente] [varchar] (50) COLLATE Latin1_General_CI_AS NULL , [troncos] [varchar] (50) COLLATE Latin1_General_CI_AS NULL ) ON [PRIMARY] GO '1111' '8,10' For this data what I need to do is return all rows from "Liga" that the value of the column Tronco is in troncos from the table Lista So for example if I query this data the return would be 1111 8 32569874 1111 10 89543964 And so on... How can I do that ?

Column != ALL (SELECT..)?
Here is the code. SELECT info1.categoria FROM ( SELECT DC2.categoria,count(DC2.ref) as quantidade FROM Disco_Categoria as DC2 GROUP BY DC2.categoria ) as info1 WHERE info1.quantidade > 2 AND info1.categoria != ALL ( SELECT DC2.categoria FROM Encomenda_Disco as ED2 INNER JOIN Disco_Categoria as DC2 ON ED2.ref=DC2.ref WHERE ED2.cod = 1 --ED.cod ) What I'm trying to do is to check if a category doesn't exist for a specific delivery (Encomenda). After reading about the predicated ALL, I decided that it was to be used, but it isn't returning the expected result. Someone correct me if I'm wrong (since probably I am ;)) but what I'm asking in the code is to compare info1.categoria with all results of DC2.Categoria to check if there is any match, returning true if there isn't any match at all. It is just not doing it. Can someone please point me at the problem so I can solve this? Thanks in advance.
