I have a class csdata which uses sql_create_20(tshares,... , and would
like to define 'tshares row' as a member of this class. Class ctran
contains members of class csdata, so it includes its header file
(csdata.h). Below are the errors.
Is it possible to include this into a header file? How? My header files
have the standard :
#ifndef __csdata_hh__
#define __csdata_hh__
I'm sure this is more of a c++ question, but using these SSQLS
structures is central to effectively using mysql++, and I'm stuck.
thanks, Don

If I understand you correctly, you are trying to store instances of a
C++ class into columns of the MySQL database. This will not work; MySQL
is not an object-oriented database. You can only use primitive types
(int, float, char*...), or types like std::string which can be readily
converted to primitives.

Also, please don't reply to an existing thread in order to post to the
list. It messes up mail readers that can do threaded reading. Make a

Hi, Below describes what I'm trying to do. I'm not trying to write an
object to the database, but
I simply want the SSQLS tshares definition (tshares shr) moved to the
header file of the class,
and therefore need to move the tshares definition. I'm trying to
develop some demonstration classes
which utilize various features of mysql++.
Thanks, Don

The SSQLS usage as shown is taken directly from examples/custom3

..... SSQLS declared in class.cp
sql_create_20(tshares.... <===SSQLS
..... in member function...
res = query.store(acct, sfx);
if (res.empty()) {
throw Acct_error(acct, sfx);
}
//because only one row can be returned
//shr = res[0]; <====would like tshares shr delcared as
class member,
tshares shr = res[0]; // using local <===rather than this local def.

..... and later to perform update ... <===this update would be in
another member function,
tshares shr2 = shr; <===thus the need for shr to be a class
member as well
// Test simple update
shr.balance += tranamt; <==== simple, rather than row numeric ref
or name lookup
query.update(shr2, shr);

This is defined in defs.h, which is included by mysql++.h. You should
