Hello:
This is my source code:
bool DBConnection::isDead()
{
SQLINTEGER stringLengthPtr;
SQLINTEGER attr;
SQLRETURN
rc=SQLGetConnectAttr(hdbc,SQL_ATTR_CONNECTION_DEAD,&attr,sizeof(attr),
&stringLengthPtr);
if(rc<0)
{
cerr<<"Source File : "<<__FILE__<<endl;
cerr<<"Line Number : "<<__LINE__<<endl;
cerr<<"SQLGetConnectAttr failed"<<endl;
cerr<<getSQLError(SQL_HANDLE_DBC,hdbc);
return true;
}
else if(attr == SQL_CD_TRUE) return true;
else return false;
}
attr always is 0 even when database is stopped.
I need an ODBC function to detect status of database connection.
Is there anything wrong in my code?
Regards,
Gu Lei
