harbour-core/harbour/source/rdd/dbcmd.c
Przemyslaw Czerpak 987fff2601 2009-02-16 17:44 UTC+0100 Przemyslaw Czerpak (druzus/at/priv.onet.pl) 
* harbour/include/dbinfo.ch
    + added DBI_ISTEMPORARY

  * harbour/include/hbapirdd.h
  * harbour/source/rdd/wafunc.c
    + added hb_rddCreateTableTemp() C function to create temporary
      table which are automatically deleted on close. All indexes and
      memo files for such tables are also in temporary files and
      automatically deleted on close. Please remember that Harbour uses
      OS functions to create temporary files so it's installation dependent
      how much disk space is available for them. Some RDDs may also do
      not create temporary files but keep everything in memory if they
      decide it's more efficient.

  * harbour/source/rdd/dbcmd.c
    + added .prg function to create temporary files:
         dbCreateTemp( <cAlias>, <aStruct>, <cRDD>, ;
                       <cCodePage>, <nConnection> ) -> <lSuccess>
      Not all RDDs have to support it. It's verified by support for
      DBI_ISTEMPORARY dbInfo() action.

  * harbour/include/hbrdddbf.h
  * harbour/include/hbrddnsx.h
  * harbour/include/hbrddcdx.h
  * harbour/include/hbrddntx.h
  * harbour/source/rdd/dbf1.c
  * harbour/source/rdd/dbffpt/dbffpt1.c
  * harbour/source/rdd/dbfntx/dbfntx1.c
  * harbour/source/rdd/dbfnsx/dbfnsx1.c
  * harbour/source/rdd/dbfcdx/dbfcdx1.c
    + added support for temporary tables in native RDDs.

   Most of above modifications were done by Viktor Szakats.
