/////////////////////////////////////////////////////////////////////////////// // 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 // 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 // Created: 9.96 // RCS-ID: $Id$ // Copyright: (c) 1996 Remstar International, Inc. // Licence: wxWindows licence, plus: // Notice: This class library and its intellectual design are free of charge for use, // modification, enhancement, debugging under the following conditions: // 1) These classes may only be used as part of the implementation of a // wxWindows-based application // 2) All enhancements and bug fixes are to be submitted back to the wxWindows // user groups free of all charges for use with the wxWindows library. // 3) These classes may not be distributed as part of any other class library, // DLL, text (written or electronic), other than a complete distribution of // the wxWindows GUI development toolkit. /////////////////////////////////////////////////////////////////////////////// /* // SYNOPSIS START // SYNOPSIS STOP */ #include "wx/wxprec.h" // Use this line for wxWindows v1.x //#include "wx_ver.h" // Use this line for wxWindows v2.x #include "wx/version.h" #if wxMAJOR_VERSION == 2 #ifdef __GNUG__ #pragma implementation "db.h" #endif #endif #ifdef DBDEBUG_CONSOLE #include "wx/ioswrap.h" #endif #ifdef __BORLANDC__ #pragma hdrstop #endif //__BORLANDC__ #if wxMAJOR_VERSION == 2 #ifndef WX_PRECOMP #include "wx/string.h" #include "wx/object.h" #include "wx/list.h" #include "wx/utils.h" #include "wx/msgdlg.h" #include "wx/log.h" #endif #include "wx/filefn.h" #include "wx/wxchar.h" #endif #if wxMAJOR_VERSION == 1 # if defined(wx_msw) || defined(wx_x) # ifdef WX_PRECOMP # include "wx_prec.h" # else # include "wx.h" # endif # endif # define wxUSE_ODBC 1 #endif #if wxUSE_ODBC #include #include #include #include #include #if wxMAJOR_VERSION == 1 #include "db.h" #elif wxMAJOR_VERSION == 2 #include "wx/db.h" #endif WXDLLEXPORT_DATA(wxDbList*) PtrBegDbList = 0; char const *SQL_LOG_FILENAME = "sqllog.txt"; char const *SQL_CATALOG_FILENAME = "catalog.txt"; #ifdef __WXDEBUG__ extern wxList TablesInUse; #endif // SQL Log defaults to be used by GetDbConnection wxDbSqlLogState SQLLOGstate = sqlLogOFF; //char SQLLOGfn[wxDB_PATH_MAX+1] = SQL_LOG_FILENAME; wxChar *SQLLOGfn = (wxChar*) SQL_LOG_FILENAME; // The wxDb::errorList is copied to this variable when the wxDb object // is closed.
