THEN RAISE past_due; -- this is not handled END IF; END; ------------- sub-block ends EXCEPTION WHEN past_due THEN -- does not handle RAISEd exception ... Retrieving the Error Code and Error Message: SQLCODE and SQLERRM In an exception handler, you can use the built-in functions SQLCODE and SQLERRM to find out which error occurred and to click site
For each exception handler, carefully decide whether to have it commit the transaction, roll it back, or let it continue. dbms_output.put_line('Complete Error Stack:'); FOR v_ErrorRec in c_ErrorCur LOOP dbms_output.put(' ' || v_ErrorRec.facility || '-'); dbms_output.put(TO_CHAR(v_ErrorRec.error_number) || ': '); dbms_output.put_line(v_ErrorRec.error_mesg); END LOOP; END PrintStacks; --=================================================== PROCEDURE Returns the sequence number under which the error is stored. A user-defined exception must be declared and then raised explicitly, using either a RAISE statement or the procedure DBMS_STANDARD.RAISE_APPLICATION_ERROR. try this
Oracle Predefined Exceptions 11g
Consider the example below. The stored procedure also had no error trap. ROWTYPE_MISMATCH 06504 -6504 It is raised when a cursor fetches value in a variable having incompatible data type. END; Omitting the exception name in a RAISE statement--allowed only in an exception handler--reraises the current exception.
But when the handler completes, the block is terminated. Example 11-4 Locator Variables for Statements that Share Exception Handler CREATE OR REPLACE PROCEDURE loc_var AUTHID DEFINER IS stmt_no POSITIVE; name_ VARCHAR2(100); BEGIN stmt_no := 1; SELECT table_name INTO name_ FROM LOGIN_DENIED ORA-01017 Invalid name and/or password for the instance. Oracle Sqlcode List An application can call raise_application_error only from an executing stored subprogram (or method).
For internal exceptions, SQLCODE returns the number of the Oracle error. Dup_val_on_index 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. If a stored subprogram exits with an unhandled exception, PL/SQL does not roll back database changes made by the subprogram. https://docs.oracle.com/cd/E11882_01/appdev.112/e25519/errors.htm 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, you might define an exception named insufficient_funds to flag overdrawn bank accounts. Oracle No_data_found The USER_DUMP_DEST initialization parameter specifies the current location of the trace files. You can also perform a sequence of DML operations where some might fail, and process the exceptions only after the entire operation is complete, as described in "Handling FORALL Exceptions with 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.
SELF_IS_NULL Your program attempts to call a MEMBER method on a null instance. https://www.techonthenet.com/oracle/errors/ The error_code is an integer in the range -20000..-20999 and the message is a character string of at most 2048 bytes. Oracle Predefined Exceptions 11g Therefore, the values of explicit cursor attributes are not available in the handler. Oracle Pragma Exception_init You can retrieve the error message with either: The PL/SQL function SQLERRM, described in "SQLERRM Function" This function returns a maximum of 512 bytes, which is the maximum length of an
Execution of the handler is complete, so the sub-block terminates, and execution continues with the INSERT statement. get redirected here You can have a single exception handler for all division-by-zero errors, bad array indexes, and so on. Although you cannot anticipate all possible errors, you can plan to handle certain kinds of errors meaningful to your PL/SQL program. All rights reserved. Oracle Error Codes
If the transaction fails, control transfers to the exception handler, where you roll back to the savepoint undoing any changes, then try to fix the problem. A specific exception handler is more efficient than an OTHERS exception handler, because the latter must invoke a function to determine which exception it is handling. So, you need not declare them yourself. navigate to this website To handle raised exceptions, you write separate routines called exception handlers.
Though they share the same name, the two past_due exceptions are different, just as the two acct_num variables share the same name but are different variables. Types Of Exceptions In Oracle Figure7-1, Figure7-2, and Figure7-3 illustrate the basic propagation rules. But remember, an exception is an error condition, not a data item.
For information about this parameter, see Oracle Database Globalization Support Guide.
NOT_LOGGED_ON ORA-01012 You tried to execute a call to Oracle before logging in. LOGIN_DENIED Your program attempts to log on to Oracle with an invalid username and/or password. Tips for Handling PL/SQL Errors In this section, you learn three techniques that increase flexibility. Oracle Raise_application_error You might want to use a FOR or WHILE loop to limit the number of tries.
Following is the simple syntax of raising an exception: DECLARE exception_name EXCEPTION; BEGIN IF condition THEN RAISE exception_name; END IF; EXCEPTION WHEN exception_name THEN statement; END; You can use above syntax Design your programs to work when the database is not in the state you expect. All rights reserved. http://setiweb.org/error-code/playstation-network-error-code-list-ps3.php Absolute value of polynomial Where is the kernel documentation?
In the example below, you calculate and store a price-to-earnings ratio for a company with ticker symbol XYZ. Predefined PL/SQL Exceptions An internal exception is raised implicitly whenever your PL/SQL program violates an Oracle rule or exceeds a system-dependent limit. If there is no enclosing block, then: If the exception handler is in a subprogram, then control returns to the invoker, at the statement after the invocation. Therefore, a PL/SQL block cannot handle an exception raised by a remote subprogram.
You can, however, declare the same exception in two different blocks. In order to use StoreStacks, an error must have been handled. Otherwise, PL/SQL replaces the error stack with error_code. ORA-00070: Command string is not valid ORA-00071: Process number must be between 1 and string ORA-00072: Process "string" is not active ORA-00073: Command string takes between string and string ...
