To help you find and fix errors, PL/SQL inserts object names, numbers, and character strings into some error messages. These message inserts are represented by name, num, and str, respectively. For example, the error message listed as
PLS-00388: undefined column name in subquery
might be issued as
PLS-00388: undefined column AMPNO in subquery
This chapter also lists the warnings that can be issued by the FIPS Flagger when it is enabled in an Oracle tool.
