RE: SQL RPG question

If I were doing this, I might do it this way:

D myStatement S 4096 Varying


myStatement = 'SELECT CMCSNAME, CMADDR1, CMCITY, CMCST#6, CMCST#3 '
+ 'FROM CUSTML1 '
+ 'WHERE (CMCSNAME>=:SHCSNAME) AND CMCSNAME LIKE '''
+ csgrpkwda + '''' ;
If SHCO# <> 0 ;
myStatement += ' AND (CMSRVCO#=' + %Char(SHCO#) ;
myStmt += ' AND CMDEL<>''D'') '
+ 'ORDER BY CMCSNAME;
Exec SQL PREPARE cursorStmt from :myStatement ;
Exec SQL DECLARE CURSOR C1 FOR cursorStmt ;

But more likely, I would do:

C/EXEC SQL DECLARE C1 CURSOR FOR
C+ SELECT CMCSNAME, CMADDR1, CMCITY, CMCST#6, CMCST#3 FROM
C+ CUSTML1 WHERE (CMCSNAME>=:SHCSNAME) AND CMCSNAME LIKE
C+ :csgrpkwda AND (:SHCO#=0 OR CMSRVCO#=:SHCO#) and
C+ CMDEL<>'D' ORDER BY CMCSNAME
C/END-EXEC

Just call your second cursor C2.
Or you could change your SQL statement Where clasue to take into account
your condition.

2.C/EXEC SQL DECLARE C1 CURSOR FOR
3.C+ SELECT CMCSNAME, CMADDR1, CMCITY, CMCST#6, CMCST#3 FROM
4.C+ CUSTML1 WHERE (CMCSNAME>=:SHCSNAME) AND CMCSNAME LIKE
5.C+ :csgrpkwda AND (CASE WHEN :SHC0# <> 0 THEN CMSRVCO#=:SHCO# ELSE END
and
6.C+ CMDEL<>'D') ORDER BY CMCSNAME
7.C/END-EXEC

I need to create one of two SQL statements conditionally, but when I try
to compile the source the compiler errors with:

SQL0051 30 289 Position 25 Cursor or procedure C1 previously
declared.

The source I'm working with is at:

http://code.midrange.com/37665d27b6.html

How do I conditionally create these SQL statements?

if you want to understand why that is, there are many good books on the
design of operating systems. please pass them along to redmond when
you're done reading them :)
