IRIX compilation fix: don't redeclare usleep() if HAVE_USLEEP is defined

[wxWidgets.git] / src / common / db.cpp

///////////////////////////////////////////////////////////////////////////////
// Name:        db.cpp
// Purpose:     Implementation of the wxDb class.  The wxDb class represents a connection
//              to an ODBC data source.  The wxDb class allows operations on the data
//              source such as opening and closing the data source.
// Author:      Doug Card
// Modified by: George Tasker
//              Bart Jourquin
//              Mark Johnson, wxWindows@mj10777.de
// Mods:        Dec, 1998:
//                -Added support for SQL statement logging and database cataloging
// Mods:        April, 1999
//                -Added QUERY_ONLY mode support to reduce default number of cursors
//                -Added additional SQL logging code
//                -Added DEBUG-ONLY tracking of wxTable objects to detect orphaned DB connections
//                -Set ODBC option to only read committed writes to the DB so all
//                   databases operate the same in that respect

    - The first one (wxDbColInf *wxDb::GetColumns(wxChar *tableName[], const
      wxChar* userID)) calls the second implementation for each separate table
      before merging the results. This makes the code easier to maintain as
      only one member (the second) makes the real work
    - wxDbColInf *wxDb::GetColumns(const wxString &tableName, int *numCols, const
      wxChar *userID) is a little bit improved
    - It doesn't anymore rely on the type-name to find out which database-type
      each column has
    - It ends by sorting the columns, so that they are returned in the same
      order they were created

 *
 * SYBASE (all)
