sql server 2008 r2 - Optional multi-valued parameters in SSRS

问题描述:

I have 3 multivalued parameters in my report.Out of them 2 are optional.

Is there any way to get the results in the report with out selecting any from the 2 optional parameters.

My stored proc checks the mulivalued parameters as (States IN (SELECT * FROM Split(@State,',')))

I have done this for a single valued parameter with WHERE CustomerId = @CustId OR @CustId IS NULL.

WorkAround:

I selected 'Allow null value', it is throwing this error

"A multi-value parameter cannot include null values"

Can anyone point me in the right direction?

网友答案:

Have a look at this article on Passing Multivalued parameters.

Basically the above link contains a workaround to meet your requirement for an optional multivalued parameter. The steps to achieve this are as follows:

  1. Replace "ALL" with " " (BLANK) in the parameter's dataset query.
  2. Assign -1 as default parameter value for your multivalued parameter.
