RE: the patch file problems

[Yigong Liu]

For complaints about "cout", add "using namespace std;" at the beginning of your program.

For complaints about "sqlplus.hh", I remember Warren changed it to mysql++.hh, right? You
also need use -I to tell the compiler where to find this header file.

Good luck.

Hello, i erase the all versions of mysql++ to my system, and i downloaded
the lastest version, (1.7.14), and i executed:

rpm -i mysql++-1.7.14-1.rh9.i386.rpm

The execution is free errors.

But i try compile the following code (a simple example from mysql++ manual):

#include <iostream>
#include <iomanip>
#include <sqlplus.hh>

int main() {
  Connection con("mysql_cpp_data");
  // The full format for the Connection constructor is
  // Connection(cchar *db, cchar *host="",
  //            cchar *user="", cchar *passwd="")
  // You may need to specify some of them if the database is not on
  // the local machine or you database username is not the same as your
  // login name, etc..

  Query query = con.query();
  // This creates a query object that is bound to con.

  query << "select * from stock";
  // You can write to the query object like you would any other ostrem

  Result res = query.store();
  // Query::store() executes the query and returns the results

  cout << "Query: " << query.preview() << endl;
  // Query::preview() simply returns a string with the current query
  // string in it.

  cout << "Records Found: " << res.size() << endl << endl;

  Row row;
  cout.setf(ios::left);
  cout << setw(17) << "Item"
       << setw(4)  << "Num"
       << setw(7)  << "Weight"
       << setw(7)  << "Price"
       << "Date" << endl
       << endl;

  Result::iterator i;
  // The Result class has a read-only Random Access Iterator
  for (i = res.begin(); i != res.end(); i++) {
    row = *i;
    cout << setw(17) << row[0]
         << setw(4)  << row[1]
         << setw(7)  << row["weight"]
      // you can use either the index number or column name when
      // retrieving the colume data as demonstrated above.
         << setw(7)  << row[3]
         << row[4] << endl;
  }
  return 0;
}

i compiled with command:

gcc ejemysqlpp.cpp -lmysqlpp -o ej

and i take too many errors:

[root@localhost mysql++]# gcc /root/ejemysqlpp.cpp -lmysqlpp -o /root/ej
