Good morning Michael,

I haven't worked a lot with stored procedures but when I have worked with them, I did it like this.

TestSQLProc()
 New stmt,status,rSet,SQLQuery  

 SET SQLQuery = "SELECT PackageName.ClassName_ProcedureName('parameter')" 

 Set stmt = ##class(%SQL.Statement).%New()
 Set status = stmt.%Prepare(SQLQuery) 

 If status'=1 
 { 
    Set return="%Prepare failed:" Do $System.Status.DisplayError(status) Quit
 } 

 Set rSet = stmt.%Execute() While rSet.%Next()
 {
0 rSet."ColumnName"
 }    

Q

I think that your problem is that you're trying to get information using Call instead of Select.

I hope it helps you.

My best,
