Random Selection From Table Variable In Subquery As A Column In Select Statement
Consider the below code: I am trying to find a way so that my select statement (which will actually be used to insert records) can randomly place values in the Source and Type columns that it selects from a list which in this case is records in a table variable. I dont really want to perform the insert inside a loop since the production version will work with millions of records. Anyone have any suggestions of how to change the subqueries that constitute these columns so that they are randomized?
SET NOCOUNT ON
Declare @RandomRecordCount as int, @Counter as int
Select @RandomRecordCount = 1000
Declare @Type table (Name nvarchar(200) NOT NULL)
Declare @Source table (Name nvarchar(200) NOT NULL)
Declare @Users table (Name nvarchar(200) NOT NULL)
Declare @NumericBase table (Number int not null)
Set @Counter = 0
while @Counter < @RandomRecordCount
begin
Insert into @NumericBase(Number)Values(@Counter)
set @Counter = @Counter + 1
end
Insert into @Type(Name)
Select 'Type: Buick' UNION ALL
Select 'Type: Cadillac' UNION ALL
Select 'Type: Chevrolet' UNION ALL
Select 'Type: GMC'
Insert into @Source(Name)
Select 'Source: Japan' UNION ALL
Select 'Source: China' UNION ALL
Select 'Source: Spain' UNION ALL
Select 'Source: India' UNION ALL

Variable For The Table Name In A SELECT Statement.
Hi,I'm trying to dynamically assign the table name for a SELECT statement but can't get it to work. Given below is my code: SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE GetLastProjectNumber (@DeptCode varchar(20)) AS BEGIN TRANSACTION SET NOCOUNT ON DECLARE @ProjectNumber int SET @ProjectNumber = 'ProjectNumber' + REPLACE(CONVERT(char,@DeptCode),'.','') SELECT MAX(@ProjectNumber) FROM 'tbl_ProjectNumber' + REPLACE(CONVERT(char,@DeptCode),'.',''); END TRANSACTION Basically, I have a bunch of tables which were created dynamically using the code from this post and now I need to access the last row in a table that matches the supplied DeptCode. This is the error I get:Msg 102, Level 15, State 1, Procedure GetLastProjectNumber, Line 29Incorrect syntax near 'tbl_ProjectNumber'. Any help would be appreciated.Thanks.

Using A Variable To Specify Table Column In Sql Statement??
Hello everyone, I'm still quite new ASP.net, Visual Web Developer 2008, and SQL. It has been a fun learning experience so far. Anyways, the site I am designing needs to allow its users to extensively search several different databases (MS SQL databases). I have followed many of the tutorials and have found it rather easy to add table adapters, gridviews and other data features that use basic SQL Select statements. One of the major database tables contains several columns which I would like to include as a search parameters from a drop down list. I was wondering if there is any way I can write a select which will pass a variable to be used as a column name to the statement? For example: SELECT DATE, GAME, EXACT, @COLNAMEFROM HistoryWHERE @COLNAME = @SOMEVARIABLE This obviously doesnt work, but thats the gist of what I want to do. Any suggestions? I need this to be simple as possible, Most everything I'm doing is done through the visual design mode. Im still slow to learn C# and apply it in the codebehind files unless I have very detailed step by step instuctions. Thanks Scott

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

Subquery Issues In A Select Statement
Hi there, I am pulling back records from the DB in this case to get Wheel information. I am pulling back based on user input, but also need to query a second table that contains the Price and model number from another table based on a field being pulled back in the original select. I am not sure if this makes sense, here is a working copy of the SQL I have , but it's not pretty. There must be another way of stating this statement that i am missing, can anyone give me some suggestiosn? SELECT tblMacPak2.*, (SELECT ListPrice FROM tblMacPakPrices WHERE WheelId = OEMWheel) AS ListPrice, (SELECT PartNumber FROM tblMacPakPrices WHERE WheelId = OEMWheel) AS PartNumber FROM tblMacPak2 WHERE (Make = N'honda') AND (Model = N'civic') AND (SubModel = N'standard') AND (YearRange = N'2006') AND (Factory_Wheel_Diameter = N'15') 3 selects in one statement...that can't be right.

Inputting Random Numbers To Table Column From Web Form
I'm grappling with this issue which I thought was basic VB programming; I'm trying to insert a random number (between 100 and 999) into a SQL table column (=Status_ID). This is input as part of a user submitting helpdesk requests via a APS.Net Web Form. The 'Status_ID' field is obviously not visible to the user but will help reference this Helpdesk request on the database.Here is the code:Protected Sub submitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submitButton.Click If Page.IsValid Then ' Define data objects Dim conn As SqlConnection Dim comm As SqlCommand ' Read the connection string from web.config Dim connectionString As String = _ ConfigurationManager.ConnectionStrings("ITNet_Students").ConnectionString ' Initialize connection conn = New SqlConnection(connectionString) ' Create command comm = New SqlCommand( _ "INSERT INTO HelpDesk (First_Name, Last_Name, StudentID, PersonalEmail," & _ "CategoryID, SubjectID, Description, StatusID) " & _ "VALUES (@First_Name, @Last_Name, @StudentID, @PersonalEmail, " & _ "@CategoryID, @SubjectID, @Description, @StatusID)", conn) ' Use randomize Randomize() Dim randomvalue As Integer ' Generate random value between 999 and 100. randomvalue = Int((900 * Rnd()) + 100) ' Add command parameters comm.Parameters.Add("@First_Name", System.Data.SqlDbType.NVarChar, 50) comm.Parameters("@First_Name").Value = fnameTextBox.Text . . . comm.Parameters.Add("@StatusID", System.Data.SqlDbType.Int) comm.Parameters("@StatusID").Value = randomvalue 'Enclose database code in Try-Catch-Finally Try ' Open connection conn.Open() ' Execute the command comm.ExecuteNonQuery() ' Reload page if the query executed successfully Response.Redirect("HelpDesk.aspx") Catch ' Display error message dbErrorMessage.Text = _ "Error submitting the help desk request!

Declaring A Table Variable Within A Select Table Joined To Other Select Tables In Query
Hello, I hope someone can answer this, I'm not even sure where to start looking for documentation on this. The SQL query I'm referencing is included at the bottom of this post. I have a query with 3 select statements joined together like tables. It works great, except for the fact that I need to declare a variable and make it a table within two of those 3. The example is below. You'll see that I have three select statements made into tables A, B, and C, and that table A has a variable @years, which is a table. This works when I just run table A by itself, but when I execute the entire query, I get an error about the "declare" keyword, and then some other errors near the word "as" and the ")" character. These are some of those errors that I find pretty meaningless that just mean I've really thrown something off. So, am I not allowed to declare a variable within these SELECT tables that I'm creating and joining? Thanks in advance, Andy Select * from ( declare @years table (years int); insert into @years select CASE WHEN month(getdate()) in (1) THEN year(getdate())-1 WHEN month(getdate()) in (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) THEN year(getdate()) END select u.fullname , sum(tx.Dm_Time) LastMonthBillhours , sum(tx.Dm_Time)/((select dm_billabledays from dm_billabledays where Dm_Month = Month(GetDate()))*8) lasmosbillingpercentage from Dm_TimeEntry tx join systemuserbase u on (tx.owninguser = u.systemuserid) where Month(tx.Dm_Date) = Month(getdate())-1 and year(dm_date) = (select years from @years) and tx.dm_billable = 1 group by u.fullname ) as A left outer join (select u.FullName , sum(tx.Dm_Time) Billhours , ((sum(tx.Dm_Time)) / ((day(getdate()) * ((5.0)/(7.0))) * 8)) perc from Dm_TimeEntry tx join systemuserbase u on (tx.owninguser = u.systemuserid) where tx.Dm_Billable = '1' and month(tx.Dm_Date) = month(GetDate()) and year(tx.Dm_Date) = year(GetDate()) group by u.fullname) as B on A.Fullname = B.Fullname Left Outer Join ( select u.fullname , sum(tx.Dm_Time) TwomosagoBillhours , sum(tx.Dm_Time)/((select dm_billabledays from dm_billabledays where Dm_Month = Month(GetDate()))*8) twomosagobillingpercentage from Dm_TimeEntry tx join systemuserbase u on (tx.owninguser = u.systemuserid) where Month(tx.Dm_Date) = Month(getdate())-2 group by u.fullname ) as C on A.Fullname = C.Fullname

Selection From Sorted Subquery Is Unsorted In SQL Server 2005
I have some relatively simple SQL that acts differently between SQL Server 2000 and 2005.

SQL Select Statement With A 'string' Variable?

Error:System.Data.SqlClient.SqlException: The column prefix 'System.Security.Principal' does not match with a table name or alias name used in the query. Here's a piece of the code that is supposed to detect the current logged in user. However, it gives the error.

Use A Variable Along With The FROM Clause In SELECT Statement
I have a table 'table_list' which contains two columns, table_name and a record_count. This table stores a list of tables and their corresponding record counts. What I am trying to do is, to be able to write a select statement, that can read each table name in the 'table_name' column, execute a select count(*) for the same, and update its record_count with the result of select count(*). This is the code in my procedure.. DECLARE @tab_list CURSOR set @tab_list = CURSOR FOR select * from table_list OPEN @tab_list DECLARE @tab_name varchar(256) DECLARE @rec_cnt int FETCH NEXT FROM @tab_list INTO @tab_name, @rec_cnt select count(*) from @tab_name This select is looping around along with FETCH till all the table names are exhausted and their counts are updated from the cursor back into the table. Problem is that, I am not able to use select count(*) from @tab_name, and its not accepting a variable there. Please help me to construct the select statement that is similiar to x=<table name> select * from x where x is a variable and the table name gets substituted. what is the syntax for it ?

But when change it to FROM article, comment; I get errors about the article_author_id and article_comment_id.

I mean, i'm making a photo gallery and on the categories table i need to know how many photos i have, so i need to count in the table photos the ones associated with the id of the category, the problem is that i'm listing categories with a datalist, is there a way so that a column on the categories table have the result of the count? Thanks in advance, if you don't understood my question feel free to ask me again and i'll try to explain it better, i really need this.

Possible To Parse A Column In A Select Statement?
I have a column called SEGMENTED_BLOCK sample data:X,X,XXX,XX,XX,TYZC123456,X,X,TOYZ654321,1234,777777I need to do something that has the effect ofSELECT(stuff before first comma) as FIRST_ITEM,(stuff after first comma, but before second) as NEXT_ITEM,(stuff after second comma but before third(if any)) as THIRD_ITEMFROM SEGMENT_XREFWHERE LOOKUP_ITEM = 12345ORDER BY FIRST_ITEMFIRST_ITEM is pretty easy, but it gets uglier fast.My attempts are horrendously ugly nested checkindex and substring statements.Is there an easier way?

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.
