You must be carefull that all member variable cannot be host variables.
In the ProC file, the #include "header.h" must be declared out of the DECLARE SECTION.
Example:
// File SqlConnect.pc
#include "SqlConnect.h"
EXEC SQL BEGIN DECLARE SECTION;
EXEC SQL INCLUDE "SqlConstant.h";
EXEC SQL END DECLARE SECTION;
CSqlConnect::CSqlConnect()
{
connected = false;
}
CSqlConnect::~CSqlConnect()
{
if (connected)
{
Disconnect();
}
}
bool CSqlConnect::Connect(const char* _string)
{
EXEC SQL BEGIN DECLARE SECTION;
char vSQLConnect[[SZ_CONNECT]];
EXEC SQL END DECLARE SECTION;
strncpy(vSQLConnect, _string, SZ_CONNECT);
EXEC SQL WHENEVER SQLERROR GOTO Err;
EXEC SQL WHENEVER SQLWARNING GOTO Err;
EXEC SQL CONNECT :vSQLConnect;
connected = true;
return true;
Err:
connected = false;
SqlTrace();
return false;
}
// other methods to define
// SqlConnect.h file
class CSqlConnect
{
bool connected;
public:
CSqlConnect();
bool Connect(const char* _string);
bool Disconnect();
bool Commit();
bool Rollback();
void SqlTrace();
}
// SqlConstant.h
#define SZ_CONNECT 100
