Find Table by UID

The overloaded method CTDatabase::FindTable() locates a table in the database given the table UID and retrieves the table name and path. The following example shows how to implement a table open function using the table UID instead of the table name.

// open table using UID

CTTable* OpenByUID(CTDatabase& ADatabase, ULONG uid, CTOPEN_MODE OpenMode)

{

   CTString tblName;

   CTString tblPath;

   CTTable* Retval;

   // locate the table in the database by uid

   if (ADatabase.FindTable(uid, tblName, tblPath))

   {

      Retval = new CTTable(ADatabase);

      if (!Retval)

         throw CTException(CTDBRET_NOMEMORY);

   
      try

      {

         Retval->Open(tblName, OpenMode);

      }

      catch (CTException& err)

      {

         delete Retval;

         throw;

      }
   }

   else

   {

      // table not found

      throw CTException(INOT_ERR);

   }

   return Retval;

}
