RE: Filling a Subfile with an SQL statement / Writing a CSV

Brian,

Here's part of a shell we use here for our SQL programs.  The SQLER5 field is 
the one that lets you know when you reach EOF.

         // Retrieve first set of records                     
         csr1Fetch() ;                                        
                                                              
         Select;                                              
                                                              
         // Fetch returned an empty set                       
         When SQLStt = EmptySet;                              
                                                              
         // Fetch returned a good record set                  
         When SQLStt = Success;                               
                                                              
            // Fetch records until end of file                
            DoW SQLStt = Success;                             
                                                              
               // Read through returned records               
               For RowCnt = 1 to SQLER3 by 1;                 
                                                              
                  // ---------------------------------------  
                  // Insert record processing logic here      
                  // ---------------------------------------  
                                                              
                  // Move to next record                      
                  RtnDtaSet@ = RtnDtaSet@ + %Size(RtnDtaSet); 
               EndFor;   // RowCnt = 1 to SQLER3 by 1         
                                                              
               // If end of table reached exit loop           
               If SQLER5 = 100;                               
                  Leave;                                      
               EndIf;

            EndDo;  // SQLStt = Success                       
                                                              
         EndSl;                                               
                                                              
         // Close cursor                                      
         csr1Close() ;

Subject: Filling a Subfile with an SQL statement / Writing a CSV


Hi All,



When I use an SQL statement to obtain information to a database, do I
need to create a cursor in order to write the data to a subfile?  Is
there a way to do something like a DoW not %eof(SQL returned records)?



The other question I have regards writing a CSV file.  Right now, we
have a null device where all of our "scratch" data is written (PRT01).
One of the users on our system needs to have the results of a query
written to a file that will be exported to an Excel spreadsheet.  I was
planning on simply writing the file to our scratch drive and have them
grab the print file using Navigator.  Does anyone know if there is a
better way to do this?



Thanks!



Brian.
