Try setting the rest of provider settings through the @.provstr parameter of
the sp_addlinkedserver.
Some examples are available in Books Online.

http://milambda.blogspot.com/Thanks. After doing some more research, I now know that this is a limitation
of SQL Server Express.
I was however able to use the following system stored procedure to change
the provider options:
EXEC master.dbo.sp_MSset_oledb_prop N'ProviderName', N'AllowInProcess', 1
I hope this can help someone else.
Thanks,
Mike

Frustrating Newbie Parameter Question
Is it possible to create a parameter where a NULL value returns ALL records
and entering a value returns the filtered data? I am filtering a date field
"ConvYear" (i.e. 2001, 2002, 2003,etc..) and I want to give the end user a
choice of filtering the dataset with a paramater or leaving it blank and
returning records with all years.
There must be an easy way to do this. I am aware of placing an iif
statement in the dataset paramater
(i.e. =iif(Parameters!Parameter1.Value = "",""," WHERE odConvYear = " +
Parameters!Parameter1.Value)),
but if the parameter is empty, how will this return ALL records? I am
confused and would appreciate any help.
My query looks like this...
SELECT OrderDetail.*
FROM OrderDetail
WHERE (fkCategoryID = 4) AND (ConvYear = ?)
Thanks!Two points, unless you have to use a filter, don't (hard for me to tell if
you are using a filter or not). A filter first retrieves all the data
defined in the dataset and then filters it. So for instance with what you
have below, you should use that query as the definition for your dataset.
Also note that for a query parameter you use @.whateveryouwanttocallit if you
are going against SQL Server and ? if going against oledb or odbc datasourc.
OK, the trick here is to use like. Then for your parameters have an All that
returns a %. To test this out first try have your labels and values be a
list that you input on the report parameters screen (you can also use a
Union query to do this as well). What I like about this solution is you
don't have to use the generic query screen plus you don't lose having a
field list. Anyway, give it a try.
SELECT OrderDetail.* FROM OrderDetail WHERE (fkCategoryID =4) AND (ConvYear like ?)

you get the list of fields, you can use the normal query designer. Whether
it is slow or not depends on the database you are going against. If it is
SQL Server 2000 and you have 20,000 records it won't even breath hard.
20,000 is nothing. I suggest trying it this way, if performance is a problem
you can always go to dynamic sql.

Freetext Search with Parameter
Hi All,
I am trying to perform a simple search but not sure what the best way is
to do it.
In my stored procedure I have 3 parameters.
1. Newspapers (if param is 0 search all)
2. Companies (if param is 0 search all)
3. Keywords
Is the only way to do these queries by using dynamic sql?
e.g.
@.SQL = @.SQL + 'Select * from Article a where freetext(a.*, @.Keyword)'
if @.Companies > 0
begin
@.SQL = @.SQL + ' and a.companies = ' + @.Companies
end
etc.
Can anyone help?
Thanks
Angela

Don't just participate in USENET...get rewarded for it!Angela,
If I correctly understand what you're trying to accomplish, then using a
IF... THEN... ELSE construct might work for you, for example:
-- FTS and IF/THEN/ELSE construct
Declare @.searchstring varchar(255)
if(@.searchstring = '1')
SELECT * FROM Article
else
SELECT * FROM Article
WHERE FREETEXT(name, @.searchstring)
-- and so, on...
If the above doesn't work for you, then try using a CASE statement. If
possible, could you post your stored proc code?
Thanks,
John

Here's my SP so far, which works but is there another way (i.e. not
using dynamic sql). On my asp page, if the user select 'Search ALL
companies' then a 0 is passed on to the SP. And like wise with
'Newspapers'
----
DECLARE @.CompanyID integer, @.NewspaperID integer, @.Keyword varchar(600)
DECLARE @.SQL varchar(8000)
SET @.SQL = ''
SET @.SQL = @.SQL + 'Select * from Article a where freetext(a.*,
@.Keyword)'
IF @.CompanyID > 0
BEGIN
SET @.SQL = @.SQL + ' and a.companies = ' + CAST(@.CompanyID as
varchar)
END
IF @.NewspaperID > 0
BEGIN
SET @.SQL = @.SQL + ' and a.newspapers = ' + CAST(@.NewspaperID as
varchar)
END
EXEC @.SQL

fRe: Multi-value parameters
Now do you know how to take multi-value parameter array values and pass to Sql Stored Proc for summing ?
Your multi value parameter gets passed to your stored proc as a comma delimited list of values, so you can use the IN keyword in your WHERE clause, like this:
Code Snippet
SELECT SUM(prices)
FROM Products
WHERE ProductID IN (@.myMultiValuedParameter)
|||i'm trying to do this but i'm getting an error when the report compiles saying "Conversion failed when converting the nvarchar value '4998,5043' to data type int."
I'm passing in a multivalue parameter called "empno" of value "4998, 5043" and my sql for it is:
SELECT... FROM ... WHERE empno IN (@.empno)
Any ideas?
|||I have not tried it yet personally, but I have read from other posts that Stored procs do not take more than one parameter from Reporting Services...Is this true...?
