DDL values with DataReader and stored procedures

P: n/a
For the code below, how could I add an item in the drop
down lists for both company and location to be an "All"
selection that would send to the stored proc.
spRptAttachments a value of "%" so that it would bring
back all attachments at all companies or all locations at
a company? Thank you, Rob.

After you bind your dropdownlist and close the datareader just do an
items.insert "Select All" at position 0. Next line would be to set
items(0).value to % or whatever character you want.

(Note sometimes I do "Choose One" as my position 0 with a value of empty
string "" so I can use a required field validator. Same concept)

Hope this helps.

Hello Rob,

I have read the code that you paste. It seems that you populate companyID and name in ddlCompany drop down list. Then
populate ddlLocation drop down list according to the selected value in ddlCompany.

In the search button onclick handler, you ran a SP according to values from drop down list.

However, I am quite clear on your questions? Could you please explain more on what you want to implement, what the
problem is so that we could provide more information to you?

Thanks very much.

What I would like to do is have the ddl have a fake record
in the list that would send to the stored procedure a wild
card like '%' that would work with the int value of the
primary key field in the table that the drop down is
displaying, hence to return all rows no matter what the id
is if that is selected.

Hello Rob,

Sorry for the late response. I am not quite familar with SQL statements. So I am not sure of how to transfer a value like % for a
int value type. What I knew is that we could only use %, * in string type values.

My suggestion is to implement it in stored procedure level. For an example, when stored procedure received one specific
value, it will return all the rows no matter what ID is selected.

Please let me know if you have any concerns on it. Thanks.

P: n/a
Hello Rob,

Do you still have any question on the issue? Please post here if you have
follow up questions.

For SQL server stored procedures, please refer to SQL books online to get
code samples. I think the logic should be:

USE pubs
GO
CREATE PROCEDURE au_info
@ID int,
AS
IF (ID == ***)
THEN
SELECT * from ...
ELSE
SELECT au_lname, au_fname, title, pub_name
FROM authors a INNER JOIN titleauthor ta
ON a.au_id = ta.au_id INNER JOIN titles t
ON t.title_id = ta.title_id INNER JOIN publishers p
ON t.pub_id = p.pub_id
WHERE au_fname = @ID
GO

Hope that helps.

Best regards,
