sql server - How to check a date range in SQL? -


i query database check if date within range of 2 dates. there start date , end date. essentially, display values using between keyword.

i date formats match well. @date1 20150520

declare @startdate date declare @enddate date declare @date1 date declare @finaldate varchar(1)  set @startdate = dateadd(day, -5, getdate()) set @enddate = getdate() set @date1 = '20150520'    select record table1 @date1 < @enddate , @date1 > @startdate

this seems make sense. though when try use if conditional null using code below:

if @date1 > @startdate , @date1 < @enddate begin set @finaldate = '1' end else if @date1 > @enddate begin set @finaldate = '2' end  select @finaldate final_date

though reason, @finaldate equates null...which not expect conditional branch.

you need additional branch on conditional, if you're cover bases:

else if @date1 <= @startdate

you've tested 1) between 2 dates , 2) greater last date. @ least 1 of should include equality check, well, or else if date equal won't match up.

now, could go plain old else block @ end, catch everything, suspect you're looking more like:

if @date1 > @startdate , @date1 < @enddate     begin         set @finaldate = '1'     end else if @date1 >= @enddate     begin         set @finaldate = '2'     end else if @date1 <= @startdate     begin         set @finaldate = '3'     end  select @finaldate final_date

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
