RE: Date data type with embedded SQL

Birgitta,

I think I would agree with you there.  I don't know how long I would have 
looked for that if Matt hadn't told me about it.  It sure seems strange that 
you can't specifically define a DS date or time field for use with SQL fetch.

Rick

Hi,

if no date format is specified in the H-Specs, date format *ISO is used for
all date fields defined in the D-Specs, as long as there is no different
date format specified.

If the MODS works with date fields defined with LIKE, but not with the data
type D, it is in my opinion a bug and should be reported.

Mit freundlichen Gru?en / Best regards

Rob,

There isn't a date format keyword on the H spec.

That's an idea.  What's the date format on your H spec?

Rick, could you should us the code for the FETCH statement?  Also, did
you make sure your RPG DATFMT() is the same as the SQL DATFMT.  The need
to be the same but I do not remember it causing a compile issue.

I recall an issue where the programmer was using dates in a explicitly
defined DS and MODSing it.  I think you have to LIKE() reference with a
MODS used on a multiple fetch situation.

Thank you,

I think this has been discussed but my search of the archives hasn't
turned up a solution yet.

I am retrieving records from a file using embedded SQL.  The code
follows.  When I compile the precompiler generates error SQL5011 that my
data structure is undefined or not usable.  In the past this usually
meant I hadn't defined a field properly.  If that's the case this time I
don't see it.  I have determined that if I remove the date field from
the DS the program will at least get past the precompiler.  A post from
the archives about using the set statement to set the SQL date data type
pointed me to an interesting Redbook but didn't provide a solution to my
situation.   I would appreciate any insight anyone may be able to
provide.

This is the data structure:
      // Data Structure for returning Application information from SQL
     d RtnDtaSet       ds                  Occurs(1280)
Based(RtnDtaSet@)
     d  AWrkQ                         3a
     d  ASysId                        1a
     d  ATrans                        7a
     d  AUser                        10a
     d  ALdDate                        D
     d  ALdTime                        T
     d  AAppl#                       12s 0
     d  ADlr#                         5s 0
     d  ALName                       30a
     d  AUpdt                         1a
     d  AApnd                         1a
     d  AHowR                         3a
     d  AGfxId                        8s 0
     d  ABrnch                        3s 0

This is how the statement is built:
      // Select statement constants

     d SelStmt1        c                   'SELECT IXWRKQ, IXSYSD,
IXTRAN, -
     d                                     IXFUSR, IXTDAT, IXTTIM,
IXAPPL, -
     d                                     IXDLR,  IXLNAM, IXUPDT,
IXAPND, -
     d                                     IXHOWR, IXGFID, IXBRCH -

     d                                     FROM ISFQUE06 WHERE IXAPPL >=
'
     d SelStmt2        c                   ' and IXWRKQ = '

     d SelStmt3        c                   ' For read only'



      /Free



        // Retrieve maintainence images

        If @QueType = 'MNT';

          SelStmt = SelStmt1 + %Char(PosAppl) + SelStmt3;



        // Retrieve Rescans & Returns

        Else;

          SelStmt = SelStmt1 + %Char(PosAppl) + SelStmt2 + @QueType +
SelStmt3;
        Endif;



      /End-Free
