c# - NHibernate Oracle CLOBs - very slow -


i have nhibernate mapping on tables in our oracle 11g database, 1 of tables contains clob column. when attempting query out ~10,000 rows of data, query takes forever. when querying subset of 200 rows, query ran 3 minutes. mathematically means it'll take 2.5 hours query 10,000 rows.

if remove clob column nhibernate mapping, same query takes ~3 seconds 200 rows, , ~2 minutes 10,000 rows.

is 1 of 'by design' issues, either oracle driver, or way nhibernate handles clobs?

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.
