We are looking into this, please.

[mauri.menabue]

ok, I am waiting !
thank

[nageswaragunupudi]

We sincerely regret the bug that crept into FWH1905. This continues in FWH1906, FWH1909 and FWH1912.

This bug is fixed in FWH2001 to be released.

For versions FWH1905 to FWH1912, we suggest this workaround. After creating the recset, please include

Code: Select all  Expand view

AEval( oRs:aStruct, { |a| If( HB_ISLOGICAL( a[ 11 ] ), nil, a[ 11 ] := .f. ) } )
 

This applies to RecSet() class only but not to the regularly used RowSet() class.

You may use this modified "maria10.prg" for your testing.

Code: Select all  Expand view

#include "fivewin.ch"

//----------------------------------------------------------------------------//

function Main()

   local oCn, oRs, nRecs

   oCn   := FW_DemoDB( 6 )
   oRs   := oCn:RecSet( "custbig", 1000 )
   oRs:nLastRec   := 1000000

   // Workaround
   if FW_VersionNo >= 19050 .and. FW_VersionNo < 20010
      AEval( oRs:aStruct, { |a| If( HB_ISLOGICAL( a[ 11 ] ), nil, a[ 11 ] := .f. ) } )
   endif
   //

   XBROWSER oRs TITLE "`Custbig` table with million records. Ready to browse in " + ;
      Transform( oRs:nReadSecs, "999.9999" ) + " Seconds"  SHOW RECID FASTEDIT
   oRs:Close()
   oCn:Close()

return nil

//----------------------------------------------------------------------------//
 

Testing the above sample:
