How To Set Column Name Dynamically?

Oct 18, 2006

HI chaps

my scenario is that, i have a table in which i have column such as col01,col02,col03....col31

i want to retrieve the records related to that column by specifying the name dynamically (by using loop) as fist three character are same ('col??') and i have to do integer increment in last two character (???01...???31). Is it possible that I can use variable for column name?, if yes how? or is there any other way to achieve this task ?

Dynamically Select Column

Sep 29, 2004

Hey all. I'm trying to create a stored proc that will update a variable column, depending on the parameter I pass it. Here's the stored proc:


CREATE PROCEDURE VoteStoredProc
(
@PlayerID int,
@VoteID int,
@BootNumber nvarchar(50)
)
AS

DECLARE @SQLStatement varchar(255)
SET @SQLStatement = 'UPDATE myTable SET '+ @BootNumber+'='+ @VoteID + ' WHERE (PlayerID = '+ @PlayerID +')'

EXEC(@SQLStatement)

GO


I get the following error:

Syntax error converting the nvarchar value 'UPDATE myTable SET Boot3=' to a column of data type int


The update statement is good, because if I use the stored proc below (hard-coded the column), it works fine.

CREATE PROCEDURE VoteStoredProc
(
@PlayerID int,
@VoteID int,
@BootNumber nvarchar(50)
)
AS

UPDATE
myTable
SET
Boot3 = @VoteID
WHERE
PlayerID = @PlayerID
GO


Is there a way to dynamically choose a column/field to select from? Or is my syntax incorrect..?
Thanks!

Dynamically Access A Column In A Table

May 21, 1999

I'm trying to create a procedure that can access a column in a table dynamically.<br>
Lets say I have the following table<br>
create table table_items<br>
(rec int identity not null,<br>
item1 int,<br>
item2 int,<br>
item3 int)<br>

and I have a procedure as such

create procedure access_item<br>
@rec int,<br>
@itemindex int,<br>
@item int as<br>
select @item = (select item1 from table_items where rec = @rec)<br>

However, the column I want to access is @itemindex.<br>
If @itemindex = 1, then set @item to item1<br>
if @itemindex = 2, then set @item to item2<br>
if @itemindex = 3, then set @item to item3<br>

I can't use a simple 'if/then' selection, because the number of columns in the table can grow, and I don't want to have to rewrite the procedure everytime a column is added.<br>
How do I do this?<br>

I tried to use an execute command, as such<br>

create procedure access_item_2<br>
@rec int,<br>
@itemindex int,<br>
@item int as<br>
declare @sql varchar(255)<br>
select @sql = "select @item = (select item" + convert(varchar(2), itemindex) + " from table_items where rec = @rec)"<br>
execute (@sql)<br>

but when the procedure runs, I get the following error:<br>
'@item is not a valid variable.'<br>

What else can I do?<br>

Please e-mail me at sam@microcsl

Dynamically Changing Column Headings

Feb 5, 2008

We have a query in which we have data in fields called TS1Min, TS1Max, TS1Avg, TS2Min, TS2Max, TS2Avg etc.

We have a different table in which we define that vale of TS1, TS2, as an example TS1 might equal RED, TS2 might equal BLUE.

We have written a query that puts TS1Min, TS1Max, TS1Avg, TS2Min, TS2Max, TS2Avg in a temp table #TEMPA

and we also put the values of RED and BLUE in another temp table #TEMPB

now we want to select * from #TEMPA but rename the headings TS1Min to display RED-TS1Min, TS1Max as RED-TS1Max, TS1Avg as RED-TS1Avg etc...

any ideas on how to do this

Pivot That Increases Columns Dynamically With Column Header As Boundary Date For Each Week

Dec 5, 2007

Hi All,

The current/ Base table would be like below,





Products

level

Date


N1

b

11/5/2007


N2

p

11/6/2007


N3

p

11/7/2007


N4

p

11/14/2007


N5

b

11/15/2007


N6

p

11/23/2007




Expected Result.







<=11/7/2007

<= 11/14/2007

<=11/21/2007


b

1

1

2


p

2

3

4


Total

3

4

6




As you can see, the above table has cumulative data.
1. It calculates the number of Products submitted till a particular date- weekly
2. The date columns should increase dynamically(if the dates in base table increases) each time the query is executed
For ex: the next date would be 11/28/2007
I tried something like, it gives me count of €˜b€™ level and €˜p€™ level products by week
declare @date1 as datetime
select @date1 = '6/30/2007'
while (@date1 != (select max(SDate) from dbo.TrendTable))
begin
set @date1 = @date1 + 7
select Level, count(Products)
from
dbo.TrendTable
where SDate < @date1
group by Level
end
what I think is required is a pivot that dynamically adds the columns for increase in date range.
/Pls suggest if any other way of achieving it.
Pls help!!!

Thanks & Regards
