You _might_ also be able to do something like:

    SELECT *
    FROM news
    WHERE newstype='1' AND global='1'
    ORDER BY concat(if(depart='center', 'A', 'B'), SortNumber) ASC

I don't have quite enough info here, but I'm going to assume that you 
want the records with depart='center' sorted first AND in alphabetic 
order, then the rest of the records in alphabetic order. I'm also 
going to assume that 'SortNumber' is actually the CHAR field you want 
the alphabetic sort on; if it isn't, replace it with the name of the 
field you want to sort by.

The intent here is to prefix the original sort order (SortNumber) 
with an 'A' for depart='center' records, so they sort before the 
other records (prefixed with a 'B').
