sql server - Speedup ExecuteReader in C# -

-

i'm using c# sqldatareader in many loops. unfortunately can't read whole table , store data in list. have create sqldatareader again , again. once sqldatareader created, fast. creation of sqldatareader via executereader takes time.

is there possibility improve creation time of sqldatareader?

i'm using .net 4.5.1 , sql server 2008.

string sql = "select current_timestamp"; var connection = connections.get();  sqlcommand sqlcommand = new sqlcommand(sql, connection); sqlcommand.commandtimeout = 0;  var reader = sqlcommand.executereader(commandbehavior.default);

thanks michael

string constring = configurationmanager.connectionstrings["applicationservices"].tostring(); sqlconnection conn = new sqlconnection(constring); conn.open(); sqlcommand cmd = new sqlcommand("select  top 50000 * users", conn); datatable dt = new datatable(); sqldataadapter da = new sqldataadapter(cmd); da.fill(dt);

please use datatable , sqldataadapter read data instead of using executereader

python - jinja2: TemplateSyntaxError: expected token ',', got 'string' -

-
i new jinja2 , having issue using python regular expression (re). in following code bold lines have error string in them. {% block content %} <div class="container"> {% l in lines %} {% if re.search(r"error", l) %} {# <<< throws error #} <b> {{ l }} </b> {% else %} {{ l }} <hr> {% endif %} {% endfor %} </div> {% endblock %} the re.search above throws following error: jinja2.exceptions.templatesyntaxerror templatesyntaxerror: expected token ',', got 'string' raw python code not supported in jinja2 template syntax. {% if re.search(r"error", l) %} replace line with {% if "error" in l %} can fix problem. if logical condition more complicated, should consider defining own custom filters (which can call python code) or complicated things in view layer. go check global namespace .

Qt4: how to send QString inside a struct via QSharedMemory -

-
i have struct struct control_data{ int column_number; qstring cell; }; i need send thread of qsharememory. read can't because qstring contains pointers inside. other ways? you have serialize struct byte array. can convert qstring const char* this: mystring.tostdstring().c_str(); but serializing qstring should work. the first step serialize struct qdatastream using qt, example here . then once struct can read , written can pass shared memory. a complete example of using qsharedmemory can found here . here relevant code: // first, test whether shared memory segment attached process. // if so, detach if (sharedmem.isattached()) { sharedmem.detach(); } ... qbuffer buffer; buffer.open( qbuffer::readwrite ); qdatastream out( &buffer ); out << youstruct; int size = buffer.size(); // size of int + size of qstring in bytes if ( !sharedmem.create( size ) ) { return; } // write shared memory sharedmem.lock(); char *to = (char*...
