: Actually my question was:
: Is a DESC or DESCEND _f_u_n_c_t_i_o_n_ available on in Oracle 9i?

Oracle has many _f_u_n_c_t_i_o_n_s_ - I would not assume the name assigned to a function within Clipper is the same as the name of a functionally equivalent function available in Oracle.

Obviously you need to choose the one that performs the same task as the Clipper function called DESCEND().

However, since I am not a Clipper programmer, I have no idea exactly what the Clipper DESCEND() function does. Therefore I cannot tell you which oracle function to use - unless I understand what it is you are trying to accomplish.

Unfortunately I have no idea from your desciption exactly what you are trying to accomplish. Received on Tue Nov 09 2004 - 19:28:09 CST
