Log:
Fixed BUG#30664. Note that this fix only works for MySQL server 
      versions 5.0.25 and newer, since earlier versions didn't consistently 
      return correct metadata for functions, and thus results from 
      subqueries and functions were indistinguishable from each other, 
      leading to type-related bugs.
