Edgar,
AFAIK you can't change the query text at report run time. There are
solutions to this type of complex querying, and let me say up front that I
recommend you put your query in a stored procedure instead of trying to put
this all into the report itself.
As Jens said, you can use dynamic SQL. This involves building your query as
a string and then calling EXEC (string). If you only have a limited number
of choices (e.g. only <, =, or >) then you can simply use IF statements and
hard code the queries for each branch.
Note: if you go the dynamic SQL route, beware of SQL injection attacks.
That's a whole subject, and too much to discuss here in one post.

Got from BOL.
Passing a Report Parameter on a URL
You can pass report parameters to a report by including them in a URL. These
URL parameters are not prefixed, because they are passed directly to the
report processing engine. For more about report parameters, see Running a
Parameterized Report.
Example
The following example uses the report parameter EmployeeID to render the
specified report:
http://server/reportserver?/Sales/Northwest/Employee Sales
Report&rs:Command=Render&EmployeeID=1234See Also
The operator cant be changed unless you use dynamic SQL.
HTH, Jens Suessmeyer.

Thank you,
I am working in a windows form that selects the report from the Report
Server and send it as .PDF to a specific location, Passing a Report
Parameter on a URL, it works well, but I want to have more flexibility in
building my query string, so I worked with a RDL Generator (Form BOL
Walkthrough – Generating RDL Using the .NET Framework), which work fine
when you are creating a report from scratch.
Is any way to change the CommandTex or Query string of an existing report
programmatically?
