member (method) to calculate the distance between points. Note that

"Point" class is computing the distance between two arbitrary points and the

arbitrary values 1 & 2 as input parameters for the Stored Procedure

"distance" whose definition is show below in Figure 28 – Distance Stored

Procedure.

Figure 28 – Distance Stored Procedure

CREATE procedure clr..distance (in x1 integer, in y1 integer, in x2

integer, in y2 integer)

returns float

{

return new DB.DBA.Point(x1, y1).distance (new DB.DBA.Point (x2, y2));

}

Step 8. Once the distance stored procedure has been created, we then publish the

procedure as a web service using the method previously shown in the section

Publishing SQL Stored Procedures as Web Services.

Step 9. Using the Virtuoso generated vsmx page, a SOAP Service can be invoked for

the procedure for testing as seen Figure 29 – Testing CLR UDT and

distance stored procedure and Figure 30 - Testing the SOAP

Operation, Distance.
