RE: SQL problem

["Tyler, Matt" <mattt@xxxxxxxxxxxxxx>]

Mark,
        I noticed that the source for getAllInvGlMf  is different in your
two source postings.  Which one is correct?

 I have a program that does a very similar process.  I load a specific
number of rows into a MODS.  I do not always get the entire request result
set.  Many times I fill only two or three entries with the remainder
elements being left at their initial values.  I am wondering if the variable
number of rows to return is having a problem with the fixed number of
elements in the MODS.  Change the field :count to 9999.  You will only get
back the number available I believe without an error or at least a warning.

Thank you,
Matt Tyler

Hello all,

Could someone tell me why this datastructure is not usable:

     PgetAllInvGlMf    B                   Export
     DgetAllInvGlMf    PI              *
     d numrecs                       10i 0

     DdtaLen           S             10i 0
     dcount            S             10i 0

     DdsData         e DS                  extname(Invglmf) occurs(9999)
     D                                      based(p_dsData)

      * retrieve the number of records to be returned
     c/exec sql
     c+ select COUNT(*) INTO :count FROM Invglmf
     c/end-exec
      * only process if there are records
     c                   if        count > 0
      * allocate the storage for the MODS
     c                   eval      dtaLen = %size(dsData) * count
     c                   alloc     dtaLen        p_dsData
      * declare the cursor
     c/exec sql
     c+ DECLARE c CURSOR FOR
     c+  SELECT * FROM Invglmf
     c/end-exec
      * open the cursor
     c/exec sql
     c+ OPEN c
     c/end-exec
      * move the records from the cursor to the MODS
     c/exec sql
     c+ FETCH FROM c FOR :count ROWS INTO :dsData
     c/end-exec
      * close the Cursor
     c/exec sql
     c+ CLOSE c
     c/end-exec
      * set the records returned and return a pointer to the MODS
     c                   eval      numRecs = count
     c                   return    p_dsData
      * no records, return null.
     c                   else
     c                   return    *null
     c                   endif

     P                 E

The precompiler is telling me that dsData is not defined or available.



Thanks,

Mark
