Subject: [mSQL] Problem regarding API (C++)
Date: Tue, 01 Apr 1997 12:57:48 CET

Hi there,

I'm curently working on a C++ program with the API myself.
I do not have much programming experinence, so maybe
someone can give me some tips.

In the object PersonRecord a string is dynamicly stored (with strlen)
I want to store the field values in a temporary buffer-object PersonRecord.
(so I can manipulate the output)
So I'm looking for a array with strings, wich are dynamicly allocated.

I realise this may be more of a programming question but I think people
who read this mailing list will see the problem.

Thanks

I'm working with a g++ compiler under:
       mSQL server version 2.0 Beta 4
       mSQL protocol version 22
       mSQL connection Localhost via UNIX socket
       Target platform Linux-2.0.18-i586

//How can I store the string values in a Record-kind-off structure?

PersonRecord::Store(char *fieldString){
  string = new char[strlen(fieldString)+1];
  strcpy(string,fieldString);
  string = fieldString;
  //cout << string; This works
};

class PersonDbase{
public:
  PersonDbase();
  int DisplayData(char field[255],char table[255]);
private:
   PersonRecord *personRecord;
};

PersonDbase::PersonDbase(){
};

int PersonDbase::DisplayData(char field[255],char table[255]){
    char query[1000] = "SELECT ";
    strcat(query,field);
    strcat(query," FROM ");
    strcat(query,table);
    if ( msqlQuery(sock,query) < 0 ){ cout << msqlErrMsg;}
    m_result *resultQuery;
    char **swap;
    resultQuery = msqlStoreResult();
    swap = msqlFetchRow(resultQuery);
    while(swap!=0){
      personRecord->Store(*swap);
      swap = msqlFetchRow(resultQuery);
    }
    //Here I can access the PersonRecord and manipulate the output
    return 1;
}
