Hello,

bool InsertDocument(ValueMap * header, vector<vm*> * rows){

	Sql query_header(my_mssql_db);
	query_header.ClearError();

	Sql query_body(my_mssql_db);
	query_body.ClearError();

	query_header.Begin();
	query_body.Begin();

This is really quite ugly code: Transaction is associated with SqlSession, so the second begin starts the second level.
