How do I change text data to numeric in SQL Server? - 


select      a.accountnumber, a.firstname, a.lastname, a.address, a.city, a.state,      a.zip, a.emailaddress, a.phonenumber, a.lastupdated, a.lastvisit,      a.totalsales, a.accountopened, a.customtext4 storecode,      case         when (a.customtext1 'jan') '1'      end dob,      getdate() extract_date      database.dbo.customer

customtext1 column has month data text data.i trying convert jan-dec numeric.

case when '' isn't working.

"is" not valid expression case statement. check online doc, have couple ways it, simplest way, repeat rest of months.

select dob =      case a.customtext1         when 'jan' '1'         when 'feb' '2'         when 'mar' '3'         else a.customtext1     end database.dbo.customer

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.
