I am trying to create a drop down list of counties, so that a report can be generated either for the county selected or if the parameter is left NULL, to create a statewide report. I've gone into the Report Parameters Menu and created a stored procedure to give me this list of counties. However when I try to run the report without selecting a county, it will not generate the report. It is not allowing me to select NULL as a value to generate my statewide report, even though I have "Allow Null Value" checked. Can you help me with allowing a NULL value to be included in my drop down list?!Thank you,Nora |

That is correct you need to allow for nulls..but you have to change your stored procedure to allow for an 'All' values:CREATE PROCEDURE rsp_customer_sites @ClientID integer, @CustomerID bigintASSET NOCOUNT ONSELECT dbo.ClientCustomerSites.SiteID, dbo.Site.SiteFROM dbo.ClientCustomerSites INNER JOIN dbo.Site ON dbo.ClientCustomerSites.SiteID = dbo.Site.SiteIDWHERE dbo.ClientCustomerSites.ClientID=@ClientID AND dbo.ClientCustomerSites.CustomerID=@CustomerIDUNION SELECT Null, 'All'ORDER BY dbo.Site.SiteSET NOCOUNT OFFGO Jon Keeping the web experience alive -- [url]http://www.web-impulse.com[/url]Imperfection living for perfection -- [url]http://jhermiz.blogspot.com/[/url] |

Thats for the combo box BTW, your resultant stored procedure which the report is based on should have something like this:...WHERE (CountryID=@CountryID OR @CountryID IS NULL)Boolean logic with an or, if the parameter has a value take the left hand side, else take the right hand side.Dont forget to set @CountryID=NULL as a default parameter.

Thank you Jon, for your help in figuring out my drop down boxes! I got that part of my report working! Yeyy!!!! Thank you! But now I'm getting the following error: Procedure expects parameter @BeginDate, which was not supplied, even though the begin and end dates were entered prior to trying to preview my report.I noticed you had a lengthy discussion with tduggan (from postings in 11/2004)... about a similar problem you were having. But even after reading all of your postings, I am still having problems. :( I am very new at this and would appreciate any advice you could give me.This is basically what I have:Under my DATA tab:1) Stored Procedure - uses BEGINDATE and ENDDATE parameters.2) Data Source dsValidRegions - gives me list of valid Regions in Texas. Code in dsValidRegions = SELECT DISTINCT Region FROM TBL_County c WHERE (Region BETWEEN '01' AND '11') UNION SELECT ' All' ORDER BY Region3) Data Source dsValidCounties - gives me list of valid Counties in Texas. Code in dsValidCounties = SELECT DISTINCT CountyName FROM TBL_County WHERE (@Region = Region) UNION SELECT ' All' ORDER BY CountyName With @Region listed under the Parameters Menu.Under my LAYOUT TAB / REPORT PARAMETERS MENU:1) Parameter Name: BeginDate Prompt: Begin Date: Data Type: String Non-queried: Default Value: None2) Parameter Name: EndDate Prompt: End Date: Data Type: String Non-queried: Default Value: None3) Parameter Name: Region Prompt: Region: Data Type: String, Allow Null Value Checked From Query: Dataset = dsValidRegions Value Field = Region Label Field = Region Default Value: From Query: Dataset = dsValidRegions Value Field = Region4) Parameter Name: CountyName Prompt: County Name: Data Type: String, Allow Null Value Checked From Query: Dataset = dsValidCountyNames Value Field = CountyName Label Field = CountyName Default Value: From Query: Dataset = dsValidCountyNames Value Field = CountyNameAny help would be greatly appreciated! Thank you.Nora :) |

Glad to see you got it working. Your other problem is simple, you need to do two things:1) In your stored procedure you have a parameter for start and end date, make sure you set these parameters with NULL defaults in case the user does not provide one:In addition...@StartDate datetime=NULL,@EndDate datetime=NULL2) Finally in your reporting services go to your report parameters.Make sure you have allowed for null values for these parameters.Jon Keeping the web experience alive -- [url]http://www.web-impulse.com[/url]Imperfection living for perfection -- [url]http://jhermiz.blogspot.com/[/url] |
