visual c++ - Oracle Stored Procedures with ADO NOT .net and VC++ -


i migrating vc++/sql server app using oracle. database access implemented using ado classes, , can't find way go through cursor returned oracle.

the sproc like:

create or replace procedure getsettings (   cv_1 out sys_refcursor ) begin    open  cv_1       select key ,              value          settings; end;

the code like:

      _commandptr pcommand;       _parameterptr pparam1;        hresult hr = pcommand.createinstance (__uuidof (command));        if (failed (hr))            return;        pcommand->activeconnection = m_pconn;       pcommand->commandtext = "getsettings";       pcommand->commandtype = adcmdstoredproc;       _recordsetptr precordset;       hr = precordset.createinstance (__uuidof (recordset));       if (failed (hr))            return;        precordset = pcommand->execute(null,null,adcmdstoredproc);

(in fact using ado classes http://www.codeproject.com/articles/1075/a-set-of-ado-classes-version-2-20#thesample02 )

the returned precordset in closed state , cannot it. imagine should pass parameter cursor, how create/use/access returned cursor using these ado functions? there no cursor parameter type can see

i stuck , appreciate help

thanks

finally found out how it, need specify special parameters in connection string tell return result set:

provider=oraoledb.oracle;user id=xxx;password=xxx;data source=tns_name;oledb.net=true;plsqlrset=true;

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
