Assuming your table is called "some_data", and has a column called "month",
you could do one
of the following:
Option 1: (The traditional solution -- Join to a "months" table)
create table months(month varchar(15), sortvalue int);
insert into months(month , sortvalue) ('January', 1);
insert into months(month , sortvalue) ('February', 2);
insert into months(month , sortvalue) ('March', 3);
...
select * from some_data
join months on months.month = some_data.month
order by months.sortvalue
Option 2: (The sexier solution -- Use an Alias)
create alias MonthSort as
$$
int monthSort(String m) {
if (m.equals("January")) return 1;
if (m.equals("February")) return 2;
if (m.equals("March")) return 3;
...
return 0;
}
$$
create table some_data(month varchar(15));
insert into some_data(month) values ('January');
insert into some_data(month) values ('February');
insert into some_data(month) values ('March');
select * from some_data order by monthSort(month)
I'm not sure which would be faster, but they'll both work.
