mysql - Separate query in single var and execute it using perl script -


i have working on perl script.

select column1,column2,column3.. table.

this query contain part in $cmd="select column1 "; , other $cmd1=",column2,column3 table"; // dynamic part, split query in 2 different variable. after execute whole query.

how query splitting part.?

use dbi; use strict; use warnings;  # input ! $cmd  = "select column1 ";  $cmd1 = ",column2,column3 table";  # wondering why have query ... # anyway, lets assume there's reason behind this!  $dbh =      dbi->connect(         'dbi:mysql:databasename;host=db.example.com', # todo change         'username',                                   # todo change         'password',                                   # todo change         { raiseerror => 1 }     ) or die "could not connect database: $dbi::errstr";  $sth = $dbh->prepare( $cmd . $cmd1 );  $sth->execute();  @row; while ( @row = $sth->fetchrow_array ) {     print "@row\n"; }

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.
