Greetings,
I am having a problem with embedding a PL/SQL block inside of a Pro*C program.
The program is supposed to delete from a table and repopulate it from another
machine. My problem is that the Pro*C precompiler is expecting a host variable
name in the 'delete' statement where you normally specify the table to delete
from. I lokked in the manuals, and it seems I have done it right unless there
is something not specified there. I also attempted to compile the example program
that does this type of thing, and it to failed to compile, with the same
error. I have included the program and a script of the output when I attempt to
compile the code. I would appreciate any suggestions anyone might have. I am
a newer person at Pro*C programming (I do mostly Forms and Menu development),
so keep that in mind when answering, please. I will summarize any answers that
I get.
Version Numbers:
Oracle Server 7.0.12.1.0
PL/SQL 2.0.14.0.1
Pro*C 1.5.6.2.1
Thanks in advance. Please send responses to mickel_at_oes.orst.edu.
