database - Data cleansing from un-normal-to normalised tables migration -


i'm cleansing data client. we're migrating legacy helpdesk ms access system customer relationship management package, ms dynamics 2015.

the llgacy system's invoice table un-normal. has in 1 table name of client, ticket number, description of helpdesk query , on.

creates scenario john smith logs helpdesk ticket, 1 instance of john smith, phone number (808-234-123) created each time helpdesk ticket

raised (and 1 row written ticket table). john smith has logged hundreds of tickets , has been entered in database as

name        phone number john smith  (808-234-123) j. smith    (808-234-123) john s.     808234123 johnny smith    ????unknown jonathan smith  234-123

and on.

what i'd 1. agree business definitive spelling of john smith , actual phone number 2. run sort of cleansing routine\package\whatever update close-to-definitive john smiths definitive john smith

this necessary because dynamics crm uses far more normalised database , want 1 john smith n records, not n john smith n records.

you use analyze tool in access

database tools, , in analyze group, click analyze table

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.
