Oracle 12c ojdbc7 driver causing issues with result.getString("DATE_COLUMN") -

-

we in process of upgrading oracle 12c , using ojdbc7(12.1.0.2.0) driver. noticed while fetching date column table using resultset.getstring("date_column"), returning daylight saving adjusted time well. please note db located in cst timezone.

say e.g.

if date in column inserted "2014-03-09 02:30:00" way day when daylight saving started in in 2014.

here line of code used fetch value.

  string sql = "select date_column a_table";      resultset rs = psmt.executequery(sql);      while (rs.next())      {         string datestring = rs.getstring("date_column");      }

here results of code snippet 2 different drivers.

odjbc6(11.2.0.3.0) - 2014-03-09 02:30:00

ojdbc7(12.1.0.2.0) - 2014-03-09 03:30:00.0

if see highlighted time fields, can see fetching 3:30:00.0 instead of 2:30 ojdbc7 driver, suggests driver getting daylight savings adjusted time of local timezone of database server, in our case cst, us.

i part appending fractional seconds mentioned in link resultset.getstring(date) differs based on driver

the problem don't need daylight saving adjusted time, need time inserted. however, using other ways of fetching date such resultset.getdate(), resultset.gettimestamp() returning dst adjusted time.

we found way out change type of date column timestamp , problem resolved.

has encountered problem oracle 12c(ojdbc7) driver?

if yes, there better way of resolving it? want avoid changing data type of existing columns timestamp.

having same issue. using rs.getstring(index) avoid daylight saving adjustment date type, ojdbc7, rs.getstring(index) adjusting time daylight saving.

i have seen instructions on running cron in advanced template, cant figure out how on basic template. have following controller in basic controllers folder. <?php namespace app\controllers; use yii\console\controller; /** * cron controller */ class croncontroller extends controller { public function actionindex() { echo "cron service runnning"; } public function actionmail($to) { echo "sending mail " . $to; } } i have navigated root of application , tried these comands yii cron php yii cron im getting unknown comand "cron" i know old question failed find actual answer this. if @ code yii exec file you'll notice requires /common/config/aliases.php file console/config/main.php. can naturally change these or copy on these advanced template. hope solves problem wanting same thing.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
