Question

I have a data set like this:

boolean name    value
0       Text10  20
1       Text1   8
0       Text4   46
1       Text9   84
1       Text5   66
0       Text2   35
0       Text9   2
1       Text6   55

Ordering by the boolean column will split the data in two sections that I want to order according to a different parameter each: The ones with boolean = 1 are ordered by value, and the rest are ordered by name, like this:

boolean name    value
1       Text1   8     # --> 1s are ordered by value
1       Text6   55
1       Text5   66
1       Text9   84
0       Text2   35    # --> 0s are ordered by name
0       Text4   46
0       Text9   2
0       Text10  20

Note: We need this to work in MySQL 4.1.11. =D

Answer 1

Notice that it can be done with multiple parts of order by that are ‘activated’ as needed.
You can check this sqlfiddle

select * from yourtable
order by 
  boolean desc, 
  case when boolean = 0 then value else null end, -- ´else null´ is redundant
  case when boolean = 1 then name  else null end  -- but is here to clarify
