Select Statement Using Column Numbers
I have a number of lookup tables in my db. Each table typically has an ID column and a 'lookup values' column. I want to create a scalar function wherein, by supplying the table name and the ID, I want to retrieve the lookup value and vice-versa. I donot want to create seperate function for each table, which is easy. One function has to return values given the table name and the value of the ID or lookup value. The problem being faced is how to construct the select statement. An Execute statement created out of column names, retrieved with Col_Name(), is not useful as Execute statement is not permitted inside a a function.

How Do I Get The Actual Name Of A Column Or Table In A Sql Select Statement?
Hello fellow .net developers, In a website I'm working on I need to be able to put all of the user tables in a database in a dropdownlist. Another dropdownlist then will autopopulate itself with the names of all the columns from the table selected in the first dropdownlist. So, what I need to know is: is there a sql statement that can return this type of information? Example: Table Names in Database: Customers, Suppliers Columns in Customers Table: Name, Phone, Email, Address I click on the word "Customers" in the first dropdownlist. I then see the words "Name", "Phone", "Email", "Address" in the second dropdownlist. I'm sure you all know this (but I'll say it anyways): I could hardcode this stuff in my code behind file, but that would be really annoying and if the table structure changes I would have to revise my code on the webpage. So any ideas on how to do this the right way would be really cool. Thanks in advance, Robert

How To Eliminate Column Header From Select Statement

You can use PLAIN whether or not a TO clause is present. If an INTO clause is included, PLAIN is ignored. " However, I tried in both SQL 2000 and SQL 7, none of them supports it. Any ideas?

Dynamic Column Names In Select Statement
I have a quick question on SQL Server. Lets say I have table Order which has column names OrderId, CustomerName, OrderDate and NumberofItems. To select the OrderID values from the table I say Select OrderId from Order. But in the select if I want the column name to be variable how do I do it. I tried the following code through a stored procedure. declare @order_id nvarchar(10) select @order_id = 'OrderID' SELECT @order_id from Order. The code above gave me the string "OrderID" as many times as there were rows in the table but I could never get the actuall values in the OrderId column. Can you please send me some ideas or code where I can get values from the column names and at the same time change the column name dynamically.

Hiding Or Removing Column Output From Select Statement
I'm executing the following... select COL1, min(COL2) from TABLE group by COL1 the table has many duplicate entries, where COL2 is the primary key and unique, but its the duplicate COL1 entries that have to be removed. I was hoping a simple "delete from table where COL1 not in (select COL1, min(COL2) from TABLE group by COL1)" would do the trick, but obviously in returning two columns from the subselect this won't work. Can I hide the COL2 output from the query that will be put in the subselect? this is a one-off thing, so i'm not overly concerned about overhead or elegance. just need to make it so. tia a

Using The ORDER BY Clause When The Ordered Column Is Not Needed In The SELECT Statement
Greetings, I have a C# application that calls a stored procedure to query the database (MSSQL 2005). I only have one field/column returned from the query but I need that column ordered. How do I use the ORDER BY clause without returning the index column which does the sorting? The first example is NOT what I want. I want something that works like the second example which only returns the 'Name' column. ALTER PROCEDURE [dbo].[MyProcedure] AS BEGIN SELECT DISTINCT A.Name, A.index FROM ... ... ORDER BY A.[Index], A.Name ASC END ALTER PROCEDURE [dbo].[MyProcedure] AS BEGIN SELECT DISTINCT A.Name FROM ... ... ORDER BY A.[Index] END Thanks

Select Statement That Will Output Related Rows With Different Column Data Per Row?
Is there a way to build a select statement that will output related rows with different column data per row? I want to return something like: rowtype| ID | value A | 123 | alpha B | 123 | beta C | 123 | delta A | 124 | some val B | 124 | some val 2 C | 124 | some val 3 etc... where for each ID, I have 3 rows that are associated with it and with different corresponding values. I'm thinking that I will have to build a temp table/cursor that will get all the ID data and then loop through it to insert each rowtype data into another temp table. i.e. each ID iteration will do something like: insert into #someTempTable (rowtype, ID, value) values ('A', 123, 'alpha') insert into #someTempTable (rowtype, ID, value) values ('B', 123, 'beta') insert into #someTempTable (rowtype, ID, value) values ('C', 123, 'delta') etc.. After my loop, I will just do a select * from #someTempTable Is there a better, more elegant way instead of using two temp tables? I am using MSSQL 2005

Can A Column Be Derived Using Substring But The Parameters Are A Result Of A Select Statement?
I have a table which has a field called Org. This field can be segmented from one to five segments based on a user defined delimiter and user defined segment length. Another table contains one row of data with the user defined delimiter and the start and length of each segment. e.g. Table 1 Org aaa:aaa:aa aaa:aaa:ab aaa:aab:aa Table 2 delim Seg1Start Seg1Len Seg2Start Seg2Len Seg3Start Seg3Len : 1 3 5 3 9 2 My objective is to use SSIS and derive three columns from the one column in Table 1 based on the positions defined in Table 2. Table 2 is a single row table. I thought perhaps I could use the substring function and nest the select statement in place of the parameters in the derived column data flow. I don't seem to be able to get this to work. Any ideas? Can this be done in SSIS? I'd really appreciate any insight that anyone might have. Regards, Bill

Random Selection From Table Variable In Subquery As A Column In Select Statement

Multiple Tables Used In Select Statement Makes My Update Statement Not Work?
I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

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

Select Statement In ASP.NET
hello all, I need to SELECT data in my ASP.NET web service from my MSSQLExpress database. I checked to INSERT data into it and it worked well , and here is the code of my insert: 1 <WebMethod()> _2 Public Function SaveNumName(ByVal UserNum As Integer, ByVal UserName As String)3 Dim DS As New SqlDataSource4 5 DS.ConnectionString = "Data Source=.SQLEXPRESS;Persist Security Info=True;Integrated Security=SSPI;Initial Catalog=tstSQL"6 ' DS.ConnectionString = ConfigurationManager.ConnectionStrings("tstSQLConnectionString1")7 DS.InsertCommandType = SqlDataSourceCommandType.Text8 DS.InsertCommand = "insert into tbl1 (number,name) values (@number,@name)"9 DS.InsertParameters.Add("number", UserNum)10 DS.InsertParameters.Add("name", UserName)11 12 DS.Insert()13 14 Return 115 End Function The previous code worked well for the insertion of data, but when I tryed the same technique with the selection of data, it didn't work, and here is my code for the select: 1 <WebMethod()> _2 Public Function GetName(ByVal Number As Integer)3 Dim Name As String4 'Dim ConnStr As String = "Data Source=.SQLEXPRESS;Persist Security Info=True;Integrated Security=SSPI;Initial Catalog=malalation_tstSQL"5 Dim GV As New GridView6 GV.Visible = False7 Dim DS As New SqlDataSource8 DS.ConnectionString = "Data Source=.SQLEXPRESS;Persist Security Info=True;Integrated Security=SSPI;Initial Catalog=tstSQL"9 10 DS.SelectCommandType = SqlDataSourceCommandType.Text11 DS.SelectCommand = "SELECT name from tbl1 where number = 1"12 ' DS.Select()13 GV.DataSource = DS14 Name = GV.Rows(0).Cells(1).Text15 Return Name16 End Function I think that the problem is with storing the result of the SELECT satatement, so what do you think??
