what correct way use int* x ? mention related link if possible unable find one. a string literal creates array object . object has static storage duration (meaning exists entire execution of program), , initialized characters in string literal. the value of string literal value of array. in contexts, there implicit conversion char[n] char* , pointer initial (0th) element of array. this: char *s = "hello"; initializes s point initial 'h' in implicitly created array object. pointer can point object ; not point value . (incidentally, should const char *s , don't accidentally attempt modify string.) string literals special case. integer literal not create object; merely yields value. this: int *ptr = 42; // invalid is invalid, because there no implicit conversion of 42 int* int . this: int *ptr = &42; // invalid is invalid, because & (address-of) operator can applied object (an "lvalue"), , there no object apply to...

due specific reasons storing events' dates 3 separate columns (instead of single datetime column): day_begin (column type: date) hour_begin (column type: time) timezone (column type: varchar) here's example row of data data these 3 columns: 2015-01-27 09:00:00 europe/rome based on information, select , rows, start date within specific utc interval (e.g. these utc start utc end of january 2015). this quite trivial if time stored in single datetime column, since can't change product accomodate specific need - need work mysql gives functions compare utc. solution: select convert_tz(concat_ws(" ", day_begin, hour_begin), timezone, "utc") the function concatenates date , hour columns , uses value timezone column second parameter convert_tz() handles time zone conversions.
