Does the "isCaseSensitive(int)" function return whether the "value" stored
in the column is case-sensitive or does it return whether the "name" of the
column is case-sensitive?
The OP is using it to determine whether the "name" is case-sensitive - which
it is always.
My assumption is that it would indicate whether the "value" is
case-sensitive - which is also true because varchar/text is case-sensitive.
The fact that different fields may or may not be case-sensitive supports
this since the "case-sensitive" property of a column "name" should be
constant throughout the database/product.
