          returned fields depend on the respective SQL type declared
          for its column (see <A
HREF="ref.sesam.html"
>SESAM
          overview</A
> for the conversions applied). SESAM
          "multiple fields" are "inlined" and treated like a sequence
          of columns.

     Note that the amount of memory used up by a large query may be
     gigantic. Use the <VAR
CLASS="parameter"
>max_rows</VAR
> parameter to
     limit the maximum number of rows returned, unless you are
     absolutely sure that your result will not use up all available
     memory.
