errors. The latter are called exceptions. Note: The language of warning and error messages depends on the NLS_LANGUAGE parameter.

The USER_DUMP_DEST initialization parameter specifies the current location of the trace files. You can find the value of this parameter by issuing SHOW PARAMETER USER_DUMP_DEST.

Compile-Time Warnings While compiling stored PL/SQL units, the PL/SQL compiler generates warnings for conditions that are not serious enough

to cause errors and prevent compilation—for example, using a deprecated PL/SQL feature. To see warnings (and errors) generated during compilation, either query the static data dictionary view *_ERRORS (described in Oracle Database Reference) or, in the SQL*Plus environment, use the command SHOW ERRORS. The message code of a PL/SQL warning has the form PLW-nnnnn. For the message codes of all PL/SQL warnings, see Oracle Database Error Messages Reference. Table 11-1 summarizes the categories of warnings. Table 11-1 Compile-Time Warning Categories Category Description Example SEVERE Condition might cause unexpected action or wrong results. Aliasing problems with parameters PERFORMANCE Condition might cause performance problems. Passing a VARCHAR2 value to a NUMBER column in an INSERT statement INFORMATIONAL Condition does not affect performance or correctness, but you might want to change it to make the code more maintainable. Code that can never run By setting the compilation parameter PLSQL_WARNINGS, you can: Enable and disable all warnings, one or more categories of warnings, or specific warnings Treat specific warnings as errors (so that those conditions must be corrected before you can compile the PL/SQL unit) You can set the value of PLSQL_WARNINGS for: Your Oracle database instance Use the ALTER SYSTEM state

Join them; it only takes a minute: Sign pl sql up Is it best practice for functions to return after raising an error in PL/SQL up vote 5 down vote favorite 1 I have a bunch of functions in packages that first check the validity of the work being requested and throw exceptions if not. Example: package body foo as function implode ( i_foo_id number ) return implode_id as not_implodable exception; implode_id number; plsql flag interpreted begin if not is_implodable(i_foo_id) then raise not_implodable; end if; //Implode logic here. return implode_id; exception when not_implodable then raise_application_error(-20005, 'Imploding is not possible on this foo.'); end implode; end foo; I have turned on warning reporting and get something like this when I compile. Warning(67,3): PLW-05005: subprogram IMPLODE returns without value at line 14. If I put a return statement after the raise_application_error then the warning goes away. Since raising the error exits the call stack, is there any good reason to return null anyways? oracle plsql share|improve this question edited Mar 11 '14 at 14:01 asked Mar 6 '14 at 19:23 David Baucum 819816 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted No. It is not a best practice for functions to return after raising and error in PL/SQL. It is possible and sometimes even recommended to add code just to shut up the compiler, like: exception when fooex then raise_application_error(-20100, 'invalid number'); return null; -- silence PLW-05005 end; Be sure to document such a peculiar code ! Generally I don't like a code that is just there
