Exit from stored procedure in sybase -


i getting parameters in stored procedure. before operating on these parameters, want validate them , if parameters not per requirement want exit stored procedure error message.

sample code:

   create proc abcd     (        zip   varchar(20),        name   varchar(20),        network varchar(1)     )      -- validation section     if (len(zip)<>5 or len(zip)<>9)     begin           print "the zip must of 5 or 9 characters"           <---- how exit here--->     end     if (len(name)<2)     begin           print "the name must of @ least 2 characters"           <---- how exit here--->     end  ---- main code

how can exit procedure once error mentioned above?

you can use return command below

-- validation section if (len(zip)<>5 or len(zip)<>9) begin       print "the zip must of 5 or 9 characters"       return 1 end if (len(name)<2) begin       print "the name must of @ least 2 characters"       return 2 end  return 0 -- on end of procedure

to catch result can use code:

declare @procresult int execute @procresult = abcd @zip = ..., @name...   select @procresult

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.
