Cause: The indicated parameter was declared with the NOCOPY hint in the subprogram specification but not in the body, or it was declared with the NOCOPY hint in the body but not in the specification.

Cause: While looking for prior declarations of a variable, constant, or label, the compiler found another declaration with the same name in the same scope. Or, the headers of subprogram in a package specification and body were not identical.

Cause: The indicated parameter was declared with the NOCOPY hint in the subprogram specification but not in the body, or it was declared with the NOCOPY hint in the body but not in the specification.

Cause: The indicated identifier was also either: o) declared in package STANDARD, or o) a SQL builtin function, or o) a pseudo-column. This situation can result in name resolution issues since the STANDARD/builtin declaration will be chosen over the local declaration in SQL statements; however the local declaration will be chosen over the STANDARD/builtin declaration outside SQL scope. (See the documentation on PL/SQL name resolution.)

Cause: A function terminated without a return value. RETURN statements with values are required for all PL/SQL functions.

Cause: Compilation of a table function causes the creation of internally- generated types. A problem occurred during creation of these types which was not severe enough to prevent the creation of the types, but which may impact the usage of the table function. See the accompanying error message for more information.

Cause: The first parameter to the pragma INLINE must be an identifier denoting a procedure or function.

Cause: The number of arguments (actual parameters) passed to the named pragma (compiler directive) is incorrect. A required argument was omitted from the argument list, or the pragma syntax is faulty (for example, a comma might be missing between two parameters).

Cause: Pragma INLINE applies only to the following statement, and can not appear immediately prior to a declaration

Cause: Pragma INLINE was applied twice to the same procedure in the same statement. The procedure will be inlined only if all duplicates specify a control value of 'YES'

Cause: A pragma INLINE was provided, but there was no call to the mentioned procedure in the next statement.

Cause: A pragma INLINE(name, 'yes') was used, but the named procedure could not be inlined.

Cause: The second parameter to the pragma INLINE governs whether or not a procedure call can be inlined. The only legal values are 'YES', meaning that the compiler should attempt to inline the call, and 'NO', meaning that the compiler must not inline the call.

Cause: The pragma was specified in an inappropriate context.

Cause: The program is so large that it overflowed a compiler limit on the size of the debug symbol table. The module was compiled with partial debugging information.

Cause: The INTO clause was incorrectly specified on a cursor declaration. It should have been specified on the FETCH statement.

Cause: Generalized invocation with explicit SELF and a dotted name was used to call the type method causing the prefix of the dotted name to be ignored.

Cause: The AUTHID clause is missing. The unit is allowed to have an AUTHID clause. If the clause is missing, DEFINER's rights are used by default. Good practice suggests that an explicit AUTHID clause should always be used.

Cause: A deprecated language element was used. The particular language element is deprecated in PL/SQL versions greater than or equal to the version number given in the message text.

Cause: A string literal was used as the parameter name in a call that used named notation.

Cause: A user-defined exception was declared but it was not given an exception number by the pragma EXCEPTION_INIT. Good practice suggests that all user-defined exceptions should be explicitly numbered.

Cause: An argument to either IN, BETWEEN or MEMBER OF was not of a comparable type. Or, if the argument was of an object type, no MAP or ORDER method was specified for the type.

Cause: PL/Scope was disabled for the current PL/SQL unit compilation because the SYSAUX tablespace is or was offline at the time of compilation. Note that PL/Scope stores identified metadata in the SYSAUX tablespace, and thus cannot function when SYSAUX is offline.

Cause: A BULK COLLECT clause was specified in a cursor declaration.

Cause: The default expression of a formal parameter referred to another formal parameter from the same subprogram declaration. This is only permitted in a formal%CHARSET expression.

Cause: Static program analysis determined that some code on the specified line would never be reached during execution. This may have been caused by expression evaluation at compile time.

Cause: An unknown inquiry directive was used. The inquiry directive is neither predefined nor user-defined.

Cause: A pragma INLINE(, 'YES') referring to the named procedure was found. The compiler will, if possible, inline this call.

Cause: A call to the procedure was inlined.

Cause: Static program analysis determined that the procedure can never be called or executed. Therefore, it has been removed to save time during compilation and space during execution.

Cause: Static program analysis determined that the procedure can never be called or executed. Therefore, it has been removed to save time during compilation and space during execution.

Cause: A pragma INLINE(, 'NO') referring to the named procedure was found. The compiler is prevented from inlining this call.

Cause: The OTHERS handler can exit without executing some form of RAISE or or a call to the standard procedure RAISE_APPLICATION_ERROR.

Cause: A PL/SQL or SQL keyword was used as defined name. Although legal, this is not recommended.

Cause: The compiled unit was so large that the compiler could not store detailed dependency information that could be used to quickly recompile the unit if it was invalidated.

Cause: The SQL statement could not be inlined.

Cause: The PLSQL_DEBUG parameter was set to TRUE forcing the optimization level to 1 (or 0 if the user selected 0) regardless of the setting of the PLSQL_OPTIMIZE_LEVEL parameter to a higher level

Cause: Native code generation was not done because the optimization was set to 1 or less.

Cause: The PLSQL_DEBUG parameter was specified.

Cause: Because the program was extremely large, analysis took an excessive amount of time or space to complete causing native compilation to be turned off.

Cause: An operation near this location is certain to raise an exception during execution; it may be a programming error because it is not an explicit RAISE.

Cause: An operation near this location computes or uses an infinite NUMBER, BINARY_FLOAT, or BINARY_DOUBLE value or a NaN BINARY_FLOAT or BINARY_DOUBLE value.

Cause: The entity was deprecated and could be removed in a future release.

Cause: The referenced entity was deprecated and could be removed in a future release.

Cause: Misplaced pragma. The pragma deprecate should follow immediately after the declaration of the entity that is being deprecated.

Cause: This entity cannot be deprecated. Deprecation only applies to entities that may be declared in a package or type specification as well as to top-level procedure and function definitions.

Cause: An IS NULL, IS NOT NULL or NVL operator was used on an object that is either never null or always null. The code may be made more efficient by eliding the call.

Cause: PRAGMA COVERAGE was encountered in a location in which it did not belong.

Cause: A conversion to a CHAR or VARCHAR type without the explicit specification of National Language Support (NLS) conversion parameters may introduce certain security risks. This often arises when the conversion happens implicitly, as when non-character types are concatenated. See the Oracle Database SQL Language Reference manual for more information about security considerations for data conversion.

Cause: A global variable was directly declared in a package specification.

Cause: After inlining, static program analysis determined that all calls to a procedure were inlined or removed. Therefore, it was removed to save time during compilation and save space during execution.

Cause: COVERAGE pragma was supplied an illegal argument.

Cause: The mode of the specified parameter was IN OUT or OUT. Use of the NOCOPY compiler hint may speed up calls to this subprogram.

Cause: The evaluation of the WHERE clause in this SQL statement will convert this column value to a different data type. This may prevent the SQL optimizer from using an index that includes this column and slow down the execution of the statement.

Cause: Using SIMPLE_INTEGER and BINARY_INTEGER or PLS_INTEGER arguments in the same arithmetic expression may inhibit certain optimizations.

Cause: This assignment may be unnecessary; the PL/SQL optimizer could not find any further use of the variable which was being set. If the assignment was being done for some side-effect such as raising a specific exception, the compiler may not have been able to understand the side-effect and this warning may be inappropriate.

Cause: This FETCH statement used BULK COLLECT without an accompanying LIMIT clause. The result set of the FETCH can be large, potentially causing memory shortage at run time.
