No it is an local var. Here's code for more information
[code]
bool CMySqlConnector::executeSelect ( std::string sql, mysqlpp::Result
&result, bool log ) //Achtung Mysql++ hat Speicherloch bei Query.store()
in combination mit std::string
{
try
{
Query query = m_clConnection.query();
//Backslashes doublen
replaceSubstring( &sql, "\\", "\\\\" );
//SQL statement an query weitergeben
query << sql.c_str();
//ausführen
result = query.store();
return true;
}
catch (std::exception &er)
{
//skipped
}
return false;
}
[/code]
When running in try block right after leaving with return debug assert
hits in .
I'm using this func in this way :
Result myResult;
executeSelect( "select * from example", myResult, true );
