sql server - SQL Function for SumIf 2012 -


this question has answer here:

i have following sql function, not running correctly, intended returned value total

set ansi_nulls on go set quoted_identifier on go  create function [dbo].[sumif](@columnname [varchar](100), @criteria [varchar](500)) returns [decimal]  begin     -- declare return variable here     declare @total decimal     declare @tablename decimal     select @total = sum(@columnname) @tablename  @criteria     return @total  end

the use syntax like

select dbo.sumif(fees.fee_amount, fees.fee_code ='b01')

so tablename need extracted columnname variable passed.

i don't think able implement function way. you're trying pass expression function don't think possible in sql server. may able dynamic sql passing in strings not cleanly you're hoping.

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.
