However, other user-defined exceptions must be raised explicitly by RAISE statements. This stops normal execution of the block and transfers control to the exception handlers. ORA-00022: Invalid session ID; access denied ORA-00023: Session references process private memory; cann... Then I reran everything just as in case4, except that the stored procedure was the one with the error trap and unnamed block the one without an error trap. this content

ROWTYPE_MISMATCH The host cursor variable and PL/SQL cursor variable involved in an assignment have incompatible return types. You can avoid unhandled exceptions by coding an OTHERS handler at the topmost level of every PL/SQL program. Also, it can use the pragma EXCEPTION_INIT to map specific error numbers returned by raise_application_error to exceptions of its own, as the following Pro*C example shows: EXEC SQL EXECUTE /* Execute For example, the following declaration raises an exception because the constant credit_limit cannot store numbers larger than 999: DECLARE credit_limit CONSTANT NUMBER(3) := 5000; -- raises an exception BEGIN ...

Oracle Predefined Exceptions 11g

When the INSERT statement implicitly raises the predefined exception INVALID_NUMBER, the exception handler does not handle it. PROGRAM_ERROR ORA-06501 Internal PL/SQL error. END; The enclosing block does not handle the raised exception because the declaration of past_due in the sub-block prevails.

From there on, the exception propagates normally. PL/SQL declares predefined exceptions globally in package STANDARD, which defines the PL/SQL environment. That is, the exception reproduces itself in successive enclosing blocks until a block has a handler for it or there is no enclosing block (for more information, see "Exception Propagation"). Oracle Sqlcode List Tips for Handling PL/SQL Errors In this section, you learn three techniques that increase flexibility.

To call RAISE_APPLICATION_ERROR, use the syntax raise_application_error(error_number, message[, {TRUE | FALSE}]); where error_number is a negative integer in the range -20000 .. -20999 and message is a character string up to Dup_val_on_index You can avoid problems by declaring scalar variables with %TYPE qualifiers and record variables to hold query results with %ROWTYPE qualifiers. CASE_NOT_FOUND ORA-06592 None of the choices in the WHEN clauses of a CASE statement is selected and there is no ELSE clause. https://docs.oracle.com/cd/E11882_01/appdev.112/e25519/errors.htm ZERO_DIVIDE 01476 1476 It is raised when an attempt is made to divide a number by zero.

Please re-enable javascript in your browser settings. Oracle No_data_found WHEN OTHERS THEN -- optional handler sequence_of_statements3 END; To catch raised exceptions, you write exception handlers. Reraising Current Exception with RAISE Statement In an exception handler, you can use the RAISE statement to"reraise" the exception being handled. Example 11-8 shows this.

Dup_val_on_index

Sometimes you can use error-checking code to avoid raising an exception, as in Example 11-7. Because predefined exceptions have names, you can write exception handlers specifically for them.

Home : Code Library : Sponsors : Privacy Oracle Pragma Exception_init Note: When using pragma RESTRICT_REFERENCES to assert the purity of a stored function, you cannot specify the constraints WNPS and RNPS if the function calls SQLCODE or SQLERRM.

But, if the need arises, you can use a locator variable to track statement execution, as follows: DECLARE stmt INTEGER := 1; -- designates 1st SELECT statement BEGIN SELECT ... news Syntax We will take a look at the syntax for Named System Exceptions in both procedures and functions. Usually raised by trying to cram a 6 character string into a VARCHAR2(5) variable ZERO_DIVIDE ORA-01476 Not only would your math teacher not let you do it, computers won't either.

So, an exception raised inside a handler propagates immediately to the enclosing block, which is searched to find a handler for the newly raised exception. The keyword OTHERS cannot appear in the list of exception names; it must appear by itself. After the exception handler runs, control transfers to the next statement of the outer block. have a peek at these guys However, an exception name can appear only once in the exception-handling part of a PL/SQL block or subprogram.

SELECT ... ... Types Of Exceptions In Oracle END; Omitting the exception name in a RAISE statement--allowed only in an exception handler--reraises the current exception. If you neglect to code a check, the error goes undetected and is likely to cause other, seemingly unrelated errors.

For more information, see "Predefined Exceptions".

When you see an error stack, or sequence of error messages, the one on top is the one that you can trap and handle. 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 In any of the preceding ALTER statements, you set the value of PLSQL_WARNINGS with this syntax: PLSQL_WARNINGS = 'value_clause' [, 'value_clause' ] ... Oracle Raise_application_error END log_error; / To Test The Error Logging Procedure exec log_error('Test', 'None', 'Did it work?'); SELECT * FROM errorlog; Database-Wide Exception Handling Using AFTER SERVERERROR CREATE TABLE error_log ( error_timestamp

You might want to use a FOR or WHILE loop to limit the number of tries. PROGRAM_ERROR 06501 -6501 It is raised when PL/SQL has an internal problem. A newline ends each call on the stack. */ WHILE v_Index < LENGTH(v_CallStack) LOOP -- v_End is the position of the newline v_End := INSTR(v_CallStack, v_NewLine, check my blog If there is no enclosing block, control returns to the host environment.

In the following example, if the SELECT INTO statement raises ZERO_DIVIDE, you cannot resume with the INSERT statement: DECLARE pe_ratio NUMBER(3,1); BEGIN DELETE FROM stats WHERE symbol = 'XYZ'; SELECT price EXCEPTION WHEN deadlock_detected THEN ... Money transfer scam When did the coloured shoulder pauldrons on stormtroopers first appear? USERENV_COMMITSCN_ERROR ORA-01725 Added for USERENV enhancement, bug 1622213.

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 These statements complete execution of the block or subprogram; control does not return to where the exception was raised. When I do a select for everything in the table a, I get the first row I inserted 'manually', the one with a1 = 1. The pragma must appear somewhere after the exception declaration in the same declarative section, as shown in the following example: DECLARE deadlock_detected EXCEPTION; PRAGMA EXCEPTION_INIT(deadlock_detected, -60); BEGIN ... -- Some operation
