Syntax for Passing a Parameter to a Stored Procedure

Posted on 2003-12-10

I have created a simple stored procedure which requires a single parameter @LocationID.  I am calling the stored procedure from a Crystal Report and attempting to pass the parameter but I am apparently doing something wrong.

This works:  {call getbatches ('350')}

The string '350' is being passed and the report works fine

This does not work:  {call getbatches (?@LocationID)}

It's probably just a syntax issue but I haven't had any luck with a number of different syntax variations.

My data source is ODBC, database is SQL2K and platform is Crystal Reports under VS.Net.

I have found this link which gets me close, but no cigar.

Any help would be greatly appreciated.

Thanks,
Dana

Try: {call getbatches ({?LocationID})}  <- If LocationID is a Parameter

Or: {call getbatches ({@LocationID})}  <- If LocationID is a Formula

I tried both and each one gives me a 'Failed to open a rowset' error message in the designer.  It seems as if the sp will only accept a literal value.

The parameter name in the stored procedure is @LocationID.  My Crystal Report parameter name is @LocationID.  This is referenced in the page header as ?@LocationID so that is how I was thinking it should be referenced in the command section.


Thanks,

{call getbatches ('350')}

You might see if this syntax works:

exec getbatches ({?@LocationID})

The parameter field is referenced in CR by surrounding it with curly braces.  The question mark indicates that it is a parameter.

What version of CR are you using, and where are you trying to call the stored procedure?

Works: exec getbatches '350'

Doesn't work: exec getbatches ({?@LocationID})

Using Crystal Reports for Visual Studio .NET

Here is the stored procedure:

CREATE procedure dbo.GetBatches
@LocationID nvarchar(50)
as
select
      BatchType,
      LocationID,
      VisitDate,
      Override,
      UserID,
      BatchSchedule
from      BatchQueue
where       LocationID = @LocationID

I have entered the call to the sp manually in the designer.  I am concerned that while in the designer after selecting the data source in the tree I only see tables and views not stored procedures.  Is this normal behavior of the designer?

Thanks,
Dana

Stored Procedures don't show by default.  Turn that option on in the settings/options screen.

Are you trying to base your report on a stored procedure instead of a table or view?  If so, when you choose your data source (after turning on the option to show stored procedures), Crystal Reports will examine the stored procedure to determine all parameters.  Previewing the report or refreshing the data will execute the report and all parameters will be populated in the stored procedure.

After reading your post I right clicked on the Details section of the report and selected Designer>Default Settings and under the Database tabe check Stored Procedure.  I then removed the @LocationID parameter that I had manually created, refreshed the database view and low and behold the parameter re-appeared (inserted automatically by Crystal) and the report works great.  Looks like I'm learning CR the hard way.

Thanks to all of you for your support.
