Best Approach To Sending Field Names Dynamically

Mar 9, 2007

Hi,I have a C# web app that searches my database table using thefollowing search parametersSearch string, criteria (< =) and the field you want to perform yoursearch on. My understanding is that stored procedure is the way to go.What's the best way of doing this using stored procedures. Can Idefine a placeholder for the field name?Ex.SELECT field1, field2... FROM Table WHERE field1='value1' where field1and value1 are both sent from code.If it's not possible then what is the best way to approach thisproblem? I see so many searches like that on the internet. I can onlydo them with inline SQL and not stored procedure.Thank youMaz.

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

Column Names

Dec 27, 2005

At my work, we are upgrading a number of MS Access 2000 databases to SQL Server 2000. Many of the columns have names that do not follow the rules for Identifiers. For example there are columns with a numeric names 1,2,3,4,5,6,7,8,9. There are also columns with a hyphen in the name and columns that begin with a number and not an underscore or an alpha character. Plus there are columns with names like first, last, position, etc. (There was also columns with reserved words used as the names. I have changed those column names in the databases that I have already converted) Will leaving these names alone create a problem? The database serves as the backend to ASP pages.

Dynamic Column Names In A SP

Jan 1, 2008

Hello,I'm still extremely novice to SQL and I've tried googling how to produce this result but I've been encountering a lot dynamic sql commands which isn't exactly what I want. If this is an ignorant question I do apologize but heres my scenario: I have a table with columns of the day, for instance: Monday_hasData (bit)Monday_DataAnd what I want to do is essentially pass in "Monday" as a parameter and rather than doing an If statement on each row, I would like to just like to do something like assign @dayCheck + "_hasData" to a variable and then use @dayCheck as part of my query.  Is this possible or am I going to have to have 7 cases? Thank you for any input,Chance
