Not easy. If your LONG is shorter than 32767, then you can, in a PL/SQL
function, fetch it into a VARCHAR2 of this size (allowed in PL/SQL) and
aplly LENGTH() to this VARCHAR2. Assuming the suitable Oracle version, I
think there is somewhere a function to convert LONGs to CLOBs - to which
you can apply a function. With Pro*C or the OCIs, you can derived the
length from the error you get when fetching into too small a buffer ...
