java - ORA-01858: a non-numeric character was found where a numeric was expected in Oracle ADF -


why above sql error oracle via java application query?

select * testschema.testtable userid = :userid , transactiondate between to_date(:start_date, 'yyyy-mm-dd') , to_date(:end_date,'yyyy-mm-dd')

i figured out. in example, there no need to_date functions on start_date , end_date. worked fine:

select * testschema.testtable userid = :userid , transactiondate between :start_date , :end_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.
