Predefined PL/SQL Exceptions
An internal exception is raised automatically if your PL/SQL program violates a database rule or exceeds a system-dependent limit. PL/SQL predefines some common ORA-n errors as exceptions. For example, PL/SQL raises the predefined exception NO_DATA_FOUND if a SELECT INTO statement returns no rows.
You can use the pragma EXCEPTION_INIT to associate exception names with other Oracle Database error codes that you can anticipate. To handle unexpected Oracle Database errors, you can use the OTHERS handler. Within this handler, you can invoke the functions SQLCODE and SQLERRM to return the Oracle Database error code and message text. Once you know the error code, you can use it with pragma EXCEPTION_INIT and write a handler specifically for that error.
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 Table 11-1.
Table 11-1 Predefined PL/SQL Exceptions
Exception Name |
ORA Error |
SQLCODE |
Raised When ... |
ACCESS_INTO_NULL |
06530 |
-6530 |
A program attempts to assign values to the attributes of an uninitialized object |
CASE_NOT_FOUND |
06592 |
-6592 |
None of the choices in the WHEN clauses of a CASE statement is selected, and there is no ELSE clause. |
COLLECTION_IS_NULL |
06531 |
-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 |
06511 |
-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 |
00001 |
-1 |
A program attempts to store duplicate values in a column that is constrained by a unique index. |
INVALID_CURSOR |
01001 |
-1001 |
A program attempts a cursor operation that is not allowed, such as closing an unopened cursor. |
INVALID_NUMBER |
01722 |
-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 |
01017 |
-1017 |
A program attempts to log on to the database with an invalid username or password. |
NO_DATA_FOUND |
01403 |
+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 must not rely on this exception being propagated if you raise it within a function that is invoked as part of a query. |
NOT_LOGGED_ON |
01012 |
-1012 |
A program issues a database call without being connected to the database. |
PROGRAM_ERROR |
06501 |
-6501 |
PL/SQL has an internal problem. |
ROWTYPE_MISMATCH |
06504 |
-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 invoke a MEMBER method, but the instance of the object type was not initialized. The built-in parameter SELF points to the object, and is always the first parameter passed to a MEMBER method. |
STORAGE_ERROR |
06500 |
-6500 |
PL/SQL ran out of memory or memory was corrupted. |
SUBSCRIPT_BEYOND_COUNT |
06533 |
-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 |
06532 |
-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 |
01410 |
-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 |
00051 |
-51 |
A time out occurs while the database is waiting for a resource. |
TOO_MANY_ROWS |
01422 |
-1422 |
A SELECT INTO statement returns more than one row. |
VALUE_ERROR |
06502 |
-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 stops 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 |
01476 |
-1476 |
A program attempts to divide a number by zero. |
