Select Statement With Run Time Field Selection

Jan 3, 2008



I have this SELECT statement.


SELECT [issueID], [name] FROM [MyIssue]


What I wanted to do is in addition to the above statement, I want to add two run time fields like this:


99 [issueID],'All Issues' [name]

So let's say the above select statements generates this list:

Summer 2007 Issue
Winter 2007 Issue

The two addition fields will make the result list like this:

01 Summer 2007 Issue
02 Winter 2007 Issue
99 All Issues


How do I accomplish this? Any help is much appreciated.

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

Nov 7, 2007

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
Select 'Source: USA'

Insert into @Users(Name)
Select 'keith' UNION ALL
Select 'kevin' UNION ALL
Select 'chris' UNION ALL
Select 'chad' UNION ALL
Select 'brian'


select
1 ProviderId, -- static value
'' Identifier,
'' ClassificationCode,
(select TOP 1 Name from @Source order by newid()) Source,
(select TOP 1 Name from @Type order by newid()) Type

from @NumericBase



SET NOCOUNT OFF

TSQL - Use ORDER BY Statement Without Insertin The Field Name Into The SELECT Statement

Oct 29, 2007

Hi guys,
I have the query below (running okay):



Code Block
SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
FROM myTables
WHERE Conditions are true
ORDER BY Field01

The results are just as I need:


Field01 Field02

------------- ----------------------

192473 8461760

192474 22810



Because other reasons. I need to modify that query to:



Code Block
SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
INTO AuxiliaryTable
FROM myTables
WHERE Conditions are true
ORDER BY Field01
SELECT DISTINCT [Field02] FROM AuxTable
The the results are:

Field02

----------------------

22810
8461760

And what I need is (without showing any other field):

Field02

----------------------

8461760
22810


Is there any good suggestion?
Thanks in advance for any help,
Aldo.

Need Help With SQL Statement (combined SELECT And WHERE At Same Time)

Oct 29, 2007

 
I am building a file repository page. For data source I use SQLDataSource and Repeater to display the categories. I am trying to achieve the result of displaying the following data: List of all "Main Categories" and all "Sub Categories" under each main category name.  Also, "Total Number of files" and "Category Description" under each "Main Category".
Sample:

Human Resources
All documents related to new hire process.
New Hire Request forms, New Hire forms, Termination Forms
Total Files:  25
 

Programs & Utilities
Windows utilities and other tools to keep you safe on the net.
Antivirus, Spyware Removal Tools, Other programs
Total Files:  37
 
My SQL2005 DB has 2 tables.

1) FileCategories. Fields(CategoryID, ParentCategoryID, CategoryName, CategoryDescription)
2) Files. (CategoryID, ParentCAtegoryID, FileTitle)
My "Main Categories" are the ones that has a NULL in ParentCategoryID field. Because they are the Parents.
My each "Sub Category" has it's own ID as well as parentCategoryID. This insures that each Sub Category corresponding to it's parent only.
Sample:

Human Resources. CategoryID=4, ParentCategoryID=NULL
New Hire Request forms. CategoryID=13, Parent CategoryID=4
New Hire Forms.                CategoryID=17, Parent CategoryID=4
Termination Forms.           CategoryID=22, Parent CategoryID=4
 

Programs & Utilities. CategoryID=6, ParentCategoryID=NULL
Antivirus.                                 CategoryID=8, Parent CategoryID=6
SpyWare Removal Tools.     CategoryID=26, Parent CategoryID=6
Other Programs.                    CategoryID=31, Parent CategoryID=6
 
When I am creating a sql Select statement first I need to choose All "CategoryIDs" where "Parent category" is NULL. Then All "CategoryIDs" where "Parent categories" are not NULL and corresponding to Main Categories.
Is it something accomplishable with SQLdataSource or I have to use ObjectDataSource or something else.
I'll be on the  site all day today (10/29/07) and tomorrow (10/30/07) checking for replies. Thanks in advance and let me know if you have any questions.

Like:
SELECT tempID AS identity(1,1), username FROM table1 ORDER BY username DESC
I want the output to be:

Need To Set A Field In A Select Statement Equal To Yes Or No If Record Exists In Separate Table

Jan 8, 2008

Hey gang,
I've got a query and I'm really not sure how to get what I need.  I've got a unix datasource that I've setup a linked server for on my SQL database so I'm using Select * From OpenQuery(DataSource, 'Query')
I am able to select all of the records from the first two tables that I need.  The problem I'm having is the last step.  I need a field in the select statement that is going to be a simple yes or no based off of if a customer number is present in a different table.  The table that I need to look into can have up to 99 instances of the customer number.  It's a "Note" table that stores a string, the customer number and the sequence number of the note.  Obviously I don't want to do a straight join and query because I don't want to get 99 duplicates records in the query I'm already pulling.
Here's my current Query this works fine:
Select *From OpenQuery(UnixData, 'Select CPAREC.CustomerNo, CPBASC_All.CustorCompName, CPAREC.DateAdded, CPAREC.Terms, CPAREC.CreditLimit, CPAREC.PowerNum
From CPAREC Inner Join CPBASC_All on CPAREC.CustomerNo = CPBASC_All.CustomerNo
Where DateAdded >= #12/01/07# and DateAdded <= #12/31/07#')
What I need to add is one more column to the results of this query that will let me know if the Customer number is found in a "Notes" table.  This table has 3 fields CustomerNo, SequenceNo, Note.
I don't want to join and select on customer number as the customer number maybe repeated as much as 99 times in the Notes table.  I just need to know if a single instance of the customer number was found in that table so I can set a column in my select statement as NotesExist (Yes or No)
Any advice would be greatly appreciated.

Appreciate all help!

Data Selection Not Happening For A Date Because Of Time Format

Jul 14, 2006

hello all,

i am making a query which select the data again a particuler date.

I insert values in the table for with current date(Today's date) and the records is inserted with the date format(2006-07-14 16:12:09),now when i run the query after 2 or 3 minutes to select the records inserted today, my query returns no results.

I think it is because of the the time (14:16 in this case) that after 2 minutes, the query looks for the records inserted at (2006-07-14 18:12 or 2006-07-14 19:12) and does not get the result.

Is there a method to not consider the time(14:16) when running the query but the query fetches the records including the records inserted at this time(14:16) no matter at what time I run the query today?

Please anyone help me!

Thanks in advance!

SQL 2012 :: Accurate Sorting Data Each Time With Millions Of Records Without Time Field?

Apr 25, 2014

Sample Table

USE [Testing]
GO
/****** Object: Table [dbo].[Testing] Script Date: 4/25/2014 11:08:18 AM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

[Code] ....

It seems to work fine with one million records.

Each primary key is unique, but the begindate is non-unique, and i guess even if i use datetime2 and add nanoseconds, from what i have read, there is a chance that i could have a duplicate datetime since the date is imported via XML from multiple sources.

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

SQL Server 2012 :: Create Dynamic Update Statement Based On Return Values In Select Statement

Jan 9, 2015

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".

Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.
