windows - CMD skips a line in batch file for no apparent reason, so what's the reason? -


simply script, simple question:

set /p customsettings="some input prompt: " if /i %customsettings:~0,1% equ y echo output

   ^-this works fine...

set custom=1 if %custom% equ 1 (     set /p customsettings="some input prompt: "     echo output )

   ^-...and works fine.
why doesn't work fine?:

set custom=1 if %custom% equ 1 (     set /p customsettings="some input prompt: "     if /i %customsettings:~0,1% equ y echo output )

the set /p customsettings line skipped when pinched between 2 if-statements.

i'm curious why happens, , how fix it.

note: problem still persists regardless of enabledelayedexpansion's setting.

you can read lot delayed expansion on site. entire if/for construct (or multiple lines within parens) loaded , expanded 1 line. have consider load-time behavior , run-time behavior. try this:

@echo off setlocal enabledelayedexpansion set custom=1 if %custom% equ 1 (     set /p customsettings="some input prompt: "     if /i "!customsettings:~0,1!"=="y" echo output )

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
