RE: sql question -- RPG400-L

Mike, 

I think you are trying to prepare the statement without closing the cursor
first. As soon as the user hits a function key to sort,close the cursor, and
then redo the prepare, delcare and open. 
This is just an assumption as I do not see your complete code. 

Hope this helps.

OK, So i've gotten away from trying to retro fit a subfile program with SQL
and am writing it from scratch.  
The program lets the user hit a command key to select a sorting option.
after selecting the sort it goes and trys to prepare and close/open my
cursor.  The problem i'm having is i'm getting a -519 error on the prepare
the 2nd time it hits the statement.  

how should i handle this??

here is the sql code.


 C                   EVAL      #SELCT2 = %TRIMR(#SELCT1) + ' ' + #SORTFL 
 C/EXEC SQL                                                              
 C+  PREPARE #SEL FROM :#SELCT2                                          
 C/END-EXEC                                                              
                                                                         
 C/EXEC SQL                                                              
  +  Declare CTLCURS SCROLL Cursor  For #SEL                             
 C/END-EXEC                                                              
                                                                         
  *OPEN THE CURSOR                                                       
 C/EXEC SQL                                                              
   +  Open CTLCURS                                    
 C/END-EXEC                                          
  * if already opened close the cursor then reopen   
 C                   IF        SQLCOD = -00000502    
 C                   EXSR      $CLOSECURS            
  *OPEN THE CURSOR                                   
 C/EXEC SQL                                          
  +  Open CTLCURS                                    
 C/END-EXEC

Using embedded sql for display file pgms is nice. It
reduces the lines of code, makes sorting on different
columns easy, and makes page up easy. 

There was an article in midrange computing about a
year ago that shows how to do it.  I think the
Sorcerer's Guide redbook also talks about.

What I do (there are probably other ways) is:
1. prepare a cursor (this is where the select is)
2. declare that cursor as scrollable
3. open that cursor
4. fetch from the cursor.  You can fetch next, prior,
first, current, or rrn.
