  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.
