Oracle Predefined Exceptions 11g
Exceptions can be internally defined (by the run-time system) or user defined. p_Top should be TRUE only at the topmost level of procedure nesting. This will be after the first occurrence of 'name' and the newline. */ v_Index := INSTR(v_CallStack, 'name') + 5; /* Loop through the string, finding each newline. up vote 20 down vote favorite 10 Where can I find a full list of all predefined Oracle pl/SQL Exceptions?
If there is no handler for a user-defined exception, the calling application gets the following error: ORA-06510: PL/SQL: unhandled user-defined exception Reraising a PL/SQL Exception Sometimes, you want to reraise an Example 11-12 Raising User-Defined Exception with RAISE_APPLICATION_ERROR CREATE PROCEDURE account_status ( due_date DATE, today DATE ) AUTHID DEFINER IS BEGIN IF due_date < today THEN -- explicitly raise exception RAISE_APPLICATION_ERROR(-20000, 'Account The inner block does not have an exception handler for exception B, so B propagates to the outer block, which does have an exception handler for it. Therefore, a PL/SQL block cannot catch an exception raised by a remote subprogram. i thought about this
Oracle Predefined Exceptions 11g
A cursor FOR loop automatically opens the cursor to which it refers. Instead, you must assign their values to local variables, then use the variables in the SQL statement, as shown in the following example: DECLARE err_num NUMBER; err_msg VARCHAR2(100); BEGIN ... For example, in Example 11-23, after the SELECT INTO statement raises ZERO_DIVIDE and the exception handler handles it, execution cannot continue from the INSERT statement that follows the SELECT INTO statement. But, according to the scope rules, enclosing blocks cannot reference exceptions declared in a sub-block.
Scope Rules for PL/SQL Exceptions You cannot declare an exception twice in the same block. SYS_INVALID_ROWID The conversion of a character string into a universal rowid fails because the character string does not represent a valid rowid. ORA-00024: Logins from more than one process not allowed i... Oracle Sqlcode List This package stores general error information in the errors table, with detailed call stack and error stack information in the call_stacks and error_stacks tables, respectively.
The optional OTHERS exception handler, which is always the last handler in a block or subprogram, acts as the handler for all exceptions not named specifically. Dup_val_on_index VALUE_ERROR An arithmetic, conversion, truncation, or size-constraint error occurs. Thus, a block or subprogram can have only one OTHERS handler. visit SELECT ...

Oracle No_data_found You code the pragma EXCEPTION_INIT in the declarative part of a PL/SQL block, subprogram, or package using the syntax PRAGMA EXCEPTION_INIT(exception_name, -Oracle_error_number); where exception_name is the name of a previously declared You can write handlers for predefined exceptions using the names in the following list: Exception Oracle Error SQLCODE Value ACCESS_INTO_NULL ORA-06530 -6530 CASE_NOT_FOUND ORA-06592 -6592 COLLECTION_IS_NULL ORA-06531 -6531 CURSOR_ALREADY_OPEN ORA-06511 -6511 INVALID_NUMBER In 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
CASE 5: Then I deleted everything from the table 1 except the a1 = 1 and did a commit. https://www.techonthenet.com/oracle/errors/ must be the last exception handler No Error Condition DECLARE ecode NUMBER; emesg VARCHAR2(200); BEGIN NULL; ecode := SQLCODE; emesg := SQLERRM; dbms_output.put_line(TO_CHAR(ecode) || '-' || emesg); Oracle Predefined Exceptions 11g Example 11-22 Displaying SQLCODE and SQLERRM Values DROP TABLE errors; CREATE TABLE errors ( code NUMBER, message VARCHAR2(64) ); CREATE OR REPLACE PROCEDURE p AUTHID DEFINER AS name EMPLOYEES.LAST_NAME%TYPE; v_code NUMBER; Oracle Pragma Exception_init Examples of internally defined exceptions include division by zero and out of memory.
For more information about PL/SQL units and compiler parameters, see "PL/SQL Units and Compilation Parameters". In the following example, you declare an exception named past_due: DECLARE past_due EXCEPTION; Exception and variable declarations are similar. Consider the following example: DECLARE pe_ratio NUMBER(3,1); BEGIN DELETE FROM stats WHERE symbol = 'XYZ'; BEGIN ---------- sub-block begins SELECT price / NVL(earnings, 0) INTO pe_ratio FROM stocks WHERE symbol = When the exception handler completes, the sub-block terminates, control transfers to the LOOP statement in the enclosing block, the sub-block starts executing again, and the transaction is retried. Oracle Error Codes
SUBSCRIPT_BEYOND_COUNT Your program references a nested table or varray element using an index number larger than the number of elements in the collection. To handle other Oracle errors, you can use the OTHERS handler. WHEN OTHERS THEN -- handles all other errors ROLLBACK; END; -- exception handlers and block end here The last example illustrates exception handling, not the effective use of INSERT statements. Defining Your Own PL/SQL Exceptions PL/SQL lets you define exceptions of your own.
The technique is: Encase the transaction in a sub-block. Types Of Exceptions In Oracle For example, the following GOTO statement is illegal: DECLARE pe_ratio NUMBER(3,1); BEGIN DELETE FROM stats WHERE symbol = 'XYZ'; SELECT price / NVL(earnings, 0) INTO pe_ratio FROM stocks WHERE symbol = CASE_NOT_FOUND None of the choices in the WHEN clauses of a CASE statement is selected, and there is no ELSE clause.
In PL/SQL, the pragma EXCEPTION_INIT tells the compiler to associate an exception name with an Oracle error number.
That lets you refer to any internal exception by name and to write a specific handler for it. Syntax for Procedures The syntax for the Named System Exception in a procedure is: CREATE [OR REPLACE] PROCEDURE procedure_name [ (parameter [,parameter]) ] IS [declaration_section] BEGIN executable_section EXCEPTION WHEN exception_name1 THEN DECLARE ---------- sub-block begins past_due EXCEPTION; BEGIN ... Oracle Raise_application_error NO_DATA_FOUND ORA-01403 The SELECT statement returned no rows or referenced a deleted element in a nested table or referenced an initialized element in an Index-By table.
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 Your program attempts to divide a number The above program displays the name and address of a customer whose ID is given. The runtime system raises them implicitly (automatically). User-defined exceptions must be raised explicitly by RAISE statements, which can also raise predefined exceptions.
So, only an OTHERS handler can catch the exception. unless you used the pragma EXCEPTION_INIT to associate the exception name with an Oracle error number, in which case SQLCODE returns that error number and SQLERRM returns the corresponding error message. For example, the following GOTO statement is illegal: DECLARE pe_ratio NUMBER(3,1); BEGIN DELETE FROM stats WHERE symbol = 'XYZ'; SELECT price / NVL(earnings, 0) INTO pe_ratio FROM stocks WHERE symbol = VALUE_ERROR ORA-06502 An arithmetic, conversion, truncation, or size-constraint error.
CASE 2: Then I modified the unnamed block so it did two good inserts and then called a stored procedure that did two good inserts and ended with one 'bad' - If a stored subprogram exits with an unhandled exception, PL/SQL does not roll back database changes made by the subprogram. dbms_output.put_line(TO_CHAR(v_TimeStamp, 'DD-MON-YY HH24:MI:SS')); dbms_output.put(' Module: ' || p_Module); dbms_output.put(' Error #' || p_SeqNum || ': '); dbms_output.put_line(v_ErrorMsg); -- Output the call stack. If ex_name_1 was raised, then statements_1 run.

You cannot use SQLCODE or SQLERRM directly in a SQL statement. The FETCH statement is expected to return no rows eventually, so when that happens, no exception is raised. Place the statement in its own sub-block with its own exception handlers. Table 11-2 summarizes the exception categories.
ZERO_DIVIDE 01476 1476 It is raised when an attempt is made to divide a number by zero. For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. SELECT ... Example 11-11 Reraising Exception DECLARE salary_too_high EXCEPTION; current_salary NUMBER := 20000; max_salary NUMBER := 10000; erroneous_salary NUMBER; BEGIN BEGIN IF current_salary > max_salary THEN RAISE salary_too_high; -- raise exception END IF;
So, your program cannot open that cursor inside the loop. Although you cannot anticipate all possible errors, you can plan to handle certain kinds of errors meaningful to your PL/SQL program. Note: An internally defined exception with a user-declared name is still an internally defined exception, not a user-defined exception.
