ORACLE PRE-DEFINE EXCEPTIONS

PL/SQL declares predefined exceptions globally in package STANDARD. You need not declare them yourself. You can write handlers for predefined exceptions using the names in the following table:

Exception	ORA Error	SQLCODE	Raise When …
ACCESS_INTO_NULL	6530	-6530	A program attempts to assign values to the attributes of an uninitialized object
CASE_NOT_FOUND	6592	-6592	None of the choices in the WHEN clauses of a CASE statement is selected, and there is no ELSE clause.
COLLECTION_IS_NULL	6531	-6531	A program attempts to apply collection methods other than EXISTS to an uninitialized nested table or varray, or the program attempts to assign values to the elements of an uninitialized nested table or varray.
CURSOR_ALREADY_OPEN	6511	-6511	A program attempts to open an already open cursor. A cursor must be closed before it can be reopened. A cursor FOR loop automatically opens the cursor to which it refers, so your program cannot open that cursor inside the loop.
DUP_VAL_ON_INDEX	1	-1	A program attempts to store duplicate values in a column that is constrained by a unique index.
INVALID_CURSOR	1001	-1001	A program attempts a cursor operation that is not allowed, such as closing an unopened cursor.
INVALID_NUMBER	1722	-1722	n a SQL statement, the conversion of a character string into a number fails because the string does not represent a valid number. (In procedural statements, VALUE_ERROR is raised.) This exception is also raised when the LIMIT-clause expression in a bulk FETCH statement does not evaluate to a positive number.
LOGIN_DENIED	1017	-1017	A program attempts to log on to Oracle with an invalid username or password.
NO_DATA_FOUND	1403	100	A SELECT INTO statement returns no rows, or your program references a deleted element in a nested table or an uninitialized element in an index-by table.
			Because this exception is used internally by some SQL functions to signal completion, you should not rely on this exception being propagated if you raise it within a function that is called as part of a query.
NOT_LOGGED_ON	1012	-1012	A program issues a database call without being connected to Oracle.
PROGRAM_ERROR	6501	-6501	PL/SQL has an internal problem.
ROWTYPE_MISMATCH	6504	-6504	The host cursor variable and PL/SQL cursor variable involved in an assignment have incompatible return types. When an open host cursor variable is passed to a stored subprogram, the return types of the actual and formal parameters must be compatible.
SELF_IS_NULL	30625	-30625	A program attempts to call a MEMBER method, but the instance of the object type has not been initialized. The built-in parameter SELF points to the object, and is always the first parameter passed to a MEMBER method.
STORAGE_ERROR	6500	-6500	PL/SQL runs out of memory or memory has been corrupted.
SUBSCRIPT_BEYOND_COUNT	6533	-6533	A program references a nested table or varray element using an index number larger than the number of elements in the collection.
SUBSCRIPT_OUTSIDE_LIMIT	6532	-6532	A program references a nested table or varray element using an index number (-1 for example) that is outside the legal range.
SYS_INVALID_ROWID	1410	-1410	The conversion of a character string into a universal rowid fails because the character string does not represent a valid rowid.
TIMEOUT_ON_RESOURCE	51	-51	A time out occurs while Oracle is waiting for a resource.
TOO_MANY_ROWS	1422	-1422	A SELECT INTO statement returns more than one row.
VALUE_ERROR	6502	-6502	An arithmetic, conversion, truncation, or size-constraint error occurs. For example, when your program selects a column value into a character variable, if the value is longer than the declared length of the variable, PL/SQL aborts the assignment and raises VALUE_ERROR. In procedural statements, VALUE_ERROR is raised if the conversion of a character string into a number fails. (In SQL statements, INVALID_NUMBER is raised.)
ZERO_DIVIDE	1476	-1476	A program attempts to divide a number by zero.
