SUPPORT / SAMPLES & SAS NOTES
Problem Note 66121: The items in a multiple-item list do not maintain the same order in which you inserted them when using ordered DATA step hashes
 |  |  |  |  |
The items in a multiple-item list do not maintain the same order in which you inserted them when using ordered DATA step hashes.
This problem occurs when the MULTIDATA:'YES' argument is specified in the DECLARE HASH statement.
The following code example illustrates the problem, and there is also a line in the comments that provides a workaround:
data _null_;
length state $ 2 city $ 32;
dcl hash h(multidata:'y');
h.definekey('state');
h.definedata('city');
h.definedone();
length state $ 2 city $ 32;
dcl hash h(multidata:'y');
h.definekey('state');
h.definedata('city');
h.definedone();
/* Uncomment the next line for the workaround */
/* if 0 then h.find_prev(); */
state = 'NC'; city = 'Raleigh'; h.add();
state = 'NC'; city = 'Cary'; h.add();
state = 'NC'; city = 'Wilson'; h.add();
state = 'NC'; city = 'Spruce Pine'; h.add();
state = 'NC';
do while (h.do_over() = 0);
put state= city=;
end;
run;
/* if 0 then h.find_prev(); */
state = 'NC'; city = 'Raleigh'; h.add();
state = 'NC'; city = 'Cary'; h.add();
state = 'NC'; city = 'Wilson'; h.add();
state = 'NC'; city = 'Spruce Pine'; h.add();
state = 'NC';
do while (h.do_over() = 0);
put state= city=;
end;
run;
When the code above is run without the workaround, the city names are listed in the output as “Raleigh, Spruce Pine, Wilson, Cary.” You would expect the output to list the items as “Raleigh, Cary, Wilson, Spruce Pine,” which is how you ordered them in the code.
