1. minor improvement to libpq++ ...

   Andreas Hauck <andreas.hauck@earthling.net> — 1998-06-18T15:48:32Z

   Hi y'all,
   
   to unify the framework of the look an feeling of c++ programs relying on
   libpq++ I propose to migrate to a consistant use of 'string' to represent any
   text rather than 'char *'.
   
   Especially I refer to PgConnection::Exec(char *), ExecCommandOk() and
   ExecTuplesOk(). It is very easy to switch over to the use of strings: in the
   headerfiles only (char * --> string) has to be changed and in the
   corresponding c++ files, the call to the c-functions becomes e.g.
   PQexec(pgConn, query) --> PQexec(pgConn, query.c_str()).
   
   The old style call via 'char *' would still be possible, since 'char *' is
   automatically convertet to 'string'. 
   
   Although I could easily change this for myself, I think it would be
   appropriate to include it in an upcoming release since it definitely results
   in a improved and more consistent handling of libpq++.
   
   Please cc: any comments or replys to 'Andreas.Hauck@earthling.net'.
   
   Cheers, Andreas

   I'm all for it, but are you sure about the automatic conversion? I don't 
   think it does that.... I just did a grep on bastring.h, and it doesn't 
   show a char* operator. And string.c_str() returns a const char*, which 
   gives all sorts of errors/warning during compile.....
