postgresql - ERROR: invalid input syntax for type timestamp: "end_time" -


new postgresql , newer jsonb. trying filter array of objects:

[{"event_slug":"test_1","start_time":"2014-10-08","end_time":"2014-10-12"}, {"event_slug":"test_2","start_time":"2013-06-24","end_time":"2013-07-02"}, {"event_slug":"test_3","start_time":"2014-03-26","end_time":"2014-03-30"}]

my query:

select l.*   locations l      , jsonb_array_elements(l.events) e  l.events @> '{"event_slug":"test_1"}' ,    e->>'end_time'::timestamp >= '2014-10-30 14:04:06 -0400'::timestamptz;

i error:

error:  invalid input syntax type timestamp: "end_time" line 5: ,    e->>'end_time'::timestamp >= '2014-10-30 14:04:06 -04...                    ^

this operator precedence issue: :: binds more tightly ->> does. need parentheses.

e->>'end_time'::timestamp

becomes

(e->>'end_time')::timestamp

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.
