ADS and autoincremental fields

[MOISES]

Hi,

Is there a way to support it in dbf databases:

Code: Select all  Expand view

{ "ID",         "+",  10,   0 }

Thank you.

Thank you.

This is already supported in DBFCDX.
fwh\samples\customer.dbf has the first field ID as autoinc field.

Yes, but I asked in ADS. I get an error: field type not supported.

this example work with ads

Code: Select all  Expand view

#include "common.ch"
#include "dbinfo.ch"
#include "ads.ch"

REQUEST ADS
//REQUEST DBFCDX, DBFFPT
REQUEST HB_LANG_ESWIN, HB_CODEPAGE_ESWIN

//EXTERNAL OrdKeyNo, OrdKeyCount, OrdKeyGoTo, OrdKeyRelPos
EXTERNAL AdsKeyNo, AdsKeyCount, AdsGetRelKeyPos, AdsSetRelKeyPos

PROCEDURE Main()
  LOCAL aStruct := { ;
         { "CHARACTER", "C", 25, 0 }, ;
         { "NUMERIC"  , "N",  8, 0 }, ;
         { "DOUBLE"   , "N",  8, 2 }, ;
         { "DATE"     , "D",  8, 0 }, ;
         { "LOGICAL"  , "L",  1, 0 }, ;
         { "MEMO1"    , "M", 10, 0 }, ;
         { "MEMO2"    , "M", 10, 0 }, ;
         { "MYRECNO"  , "+", 4, 0  }  } /*work ok with + and Autoinc*/

  hb_LangSelect(  "ESWIN" )
  hb_SetCodePage( "ESWIN" )

  RddSetDefault( "ADS" )
   
  set date brit
  set cent on
  set opti on
  set dele on
 
  SET SERVER LOCAL
  SET AXS LOCKING OFF
  SET RIGHTS CHECKING OFF
  SET CHARTYPE TO ANSI
  SET FILETYPE TO ADT
 
  SetMode(25,80)
  cls
 
  WAIT "Exist table: " + iif( hb_dbExists( "testdbf" ), "Si", "No" )
 
  IF !hb_dbExists( "testdbf" )
    DbCreate( "testdbf", aStruct, "ADS", .T., "mylias" )
    index on CHARACTER to char01
  ELSE
    USE testdbf NEW ALIAS myalias
    SET INDEX TO char01
    WAIT "IndexOrder: " + hb_ntos( OrdNumber() ) + " / " + OrdKey()
  ENDIF
 
  Browse()
 
  use
 
RETURN

Thank you very much, Carlos.

The problem occurs if a DBF with autoincremental created with DBFCDX is opened with ADS, then it fails.

We must re-generate the table with the ADS driver.

[carlos vargas]

yes, not work. ace fail open customer.dbf from fwh sample folder!

[MOISES]

Yes, thats the problem.

It seems that ADS is abandoned by Sybase. Am i right?
