sqlite - Recursive Query CTE in SQL Lite -


i have following table structure. (i new sql lite)

create table relations  ( code int, parentcode int , fname text ) go insert relations values(1,null,'a'); insert relations values(2,null,'b'); insert relations values(3,2,'c'); insert relations values(4,3,'d');

i want initial parent of code =4 : i.e. values 2 null b

i not able figure out how write recursive query in sqllite. in advance..

was version issue.. query not working & getting syntax error. upgraded 3.7.17 3.8.7.4 version & worked..

with recursive   works(code,parent) (    select code,parentcode relations a.code=4     union     select relations.code, relations.parentcode relations , works      relations.code=works.parent   ) select * works parent null

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.
