Re: Using SQL within RPG

Eric,

I sent you a very basic attachment off list.  Below is the code, not as an
attachment.  Read it over and let me know if you have any questions.  This
program doesn't really do anything but it is important that you know what a
cursor is.

     D HostVar         S            200
     D SortCol         S             10A
     D fileds        E DS                  extname(aaakey)

     C                   eval      SortCol='loc'
     C                   exsr      test
     C                   eval      SortCol='comp'
     C                   exsr      test

     C                   eval      *inlr=*on
      *********************************************************

     C     test          BegSr

     C                   eval      HostVar='Select loc, comp, coname ' +
     C                                      'from aaakey ' +
     C                                      'order by '  + SortCol +
     C                                      'for fetch only'

     C/EXEC SQL
     C+ prepare stmt from :hostvar
     C/END-EXEC

     C/EXEC SQL
     C+ Declare C1 cursor for stmt
     C/END-EXEC

     C/EXEC SQL
     C+ Open C1
     C/END-EXEC

     C/EXEC SQL
     C+ Fetch C1 into :loc, :comp, :coname
     C/END-EXEC

     C                   dow       sqlcod=*zeros

     C* load subfile record

     C/EXEC SQL
     C+ Fetch C1 into :loc, :comp, :coname
     C/END-EXEC
     C                   enddo

     C/EXEC SQL
     C+ Close C1
     C/END-EXEC

     C                   EndSr

Can anyone recommend a book or have some samples of using SQL calls within
a
RPG program?


thanks...
