sql - How do you change a scalar function used by a computed column -


i have persisted computed column uses scalar function assign data it. noticed can't change function once it's used column. in test environment, deleted , re-added column. once in production, won't option. table has 24 million rows , no 1 want drop , re-add column.

is there way change function without dropping column? if function calls function, functions in chain not allowed changed?

i realize doing can create inconsistencies in existing data versus data being calculated going forward. don't care that.

thanks, kevin

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.
