AW: SQL logical file equivalent

["BirgittaHauser" <Hauser@xxxxxxxxxxxxxxx>]

Hi Gerald,

Not sure what you are doing wrong!
I never had problems compiling sources where I specified SQL indexes in the
F-Specs.

Here an example:
1. I have the following DDS described physical file (ORDHDR):
A                                      UNIQUE                          
A          R ORDERHDR                                                  
A            ORHNBR         5          COLHDG('ORDER NUMBER      ')    
A                                      ALIAS(ORDER_NUMBER   )          
A            CUSNBR         5          COLHDG('CUSTOMER NUMBER   ')    
A                                      ALIAS(CUSTOMER_NUMBER)          
A            ORHDTE          L         COLHDG('ORDER DATE        ')    
A                                      ALIAS(ORDER_DATE     )          
A            ORHDLY          L         COLHDG('ORDER DELIVERY    ')    
A                                      ALIAS(ORDER_DELIVERY )          
A            SRNBR         10          COLHDG('ORDER SALESREP    ')    
A                                      ALIAS(ORDER_SALESREP )          
A            ORHTOT        11P 2       COLHDG('ORDER TOTAL       ')    
A                                      ALIAS(ORDER_TOTAL    )    
A          K ORHNBR     

2. There is a SQL index over this physical file defined as follows:
Create Index OrdHdrI01 ON MySchema/ORDHDR         
     (ORDER_DATE, CUSTOMER_NUMBER, ORDER_NUMBER);  

3. Here is a snippet from an RPG Program where I define this index in the
F-Specs:
H Option(*NoDebugIO) Debug                                      
H DatFmt(*ISO)  TimFmt(*ISO)                                    
 ***************************************************************
FORDHDRI01 IF   E           k DISK    Rename(OrdHdrF: OrdHdrF1) 
 ***************************************************************
 * D-Specs
 ***************************************************************
 /Free
   ... Some Code 
   SetLL (D'2004-07-10': '55555') OrdHdrF1;  
   If Not %Equal;                                
      Return;                            
   EndIf;                                          

   ... Other Code
   ReadE (KeyDate: KeyCust) OrdHdrF1;

 /End-Free

Hope this helps!

Mit freundlichen Grüßen / Best regards

Birgitta,

"A SQL Index can be used with native I/O like any keyed DDS described 
logical file."

I've tried that but never found it to be acceptable to the RPG compiler.

Care to share an example?
