Pl Sql Error Description

Contents

If the optional third parameter is TRUE, the error is placed on the stack of previous errors. SELF_IS_NULL Your program attempts to call a MEMBER method on a null instance. In Example 11-15, the VALUE_ERROR exception handler is in the same block as the declaration that raises VALUE_ERROR. Because a block can reference only local or global exceptions, enclosing blocks cannot reference exceptions declared in a sub-block.

For more information, see "Predefined Exceptions". You must raise user-defined exceptions explicitly. Otherwise, PL/SQL replaces the error stack with error_code. BEGIN * ERROR at line 1: ORA-01476: divisor is equal to zero ORA-06512: at "HR.DESCENDING_RECIPROCALS", line 19 ORA-06510: PL/SQL: unhandled user-defined exception ORA-06512: at line 2 Example 11-21 is like Example

Functions For Error Trapping Are Contained In Which Section Of A Pl/sql Block

Declaring PL/SQL Exceptions Exceptions can be declared only in the declarative part of a PL/SQL block, subprogram, or package. If an error occurs in the sub-block, a local handler can catch the exception. The inner block has an exception handler for A, so A does not propagate. The message begins with the Oracle error code.

STORAGE_ERROR ORA-06500 -6500 PL/SQL ran out of memory or memory was corrupted. Alternatively, you can use the pragma EXCEPTION_INIT to associate exception names with Oracle error codes. 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. Oracle Sqlcode List Problems include Too much code.

With exceptions, you can handle errors conveniently without the need to code multiple checks, as follows: BEGIN SELECT ... Command> DECLARE > v_deptno NUMBER := 500; > v_name VARCHAR2 (20) := 'Testing'; > e_invalid_dept EXCEPTION; > BEGIN > UPDATE departments > SET department_name = v_name > WHERE department_id = v_deptno; Such action, for example, might consist of a rollback to the beginning of the transaction. https://docs.oracle.com/cd/E11882_01/timesten.112/e21639/exceptions.htm Also, PL/SQL does not roll back database work done by the subprogram.

RAISE_APPLICATION_ERROR is part of package DBMS_STANDARD, and as with package STANDARD, you do not need to qualify references to it. Oracle Raise Exception With Message If you know that your database operations might raise specific internally defined exceptions that do not have names, then give them names so that you can write exception handlers specifically for How to create a table of signs tr command has no effect when used in $() and saved in a variable first order condtion of Lagrangian if (λ x . The PL/SQL language does not include these constructs.

Pl Sql Sqlcode

The outer block does not have an exception handler for C, so PL/SQL returns an unhandled exception error to the host environment. https://docs.oracle.com/cd/E11882_01/appdev.112/e25519/errors.htm You cannot use SQLCODE directly in a SQL statement. Functions For Error Trapping Are Contained In Which Section Of A Pl/sql Block Skip Headers PL/SQL User's Guide and Reference Release 2 (9.2) Part Number A96624-01 Home Book List Contents Index Master Index Feedback 7 Handling PL/SQL Errors There is nothing more exhilarating than Oracle Sql Error Codes into the errors table INSERT INTO errors (module, seq_number, error_stack, call_stack, timestamp) VALUES (p_Module, v_SeqNum, v_ErrorStack, v_CallStack, SYSDATE); /* Unwind the error stack to get

Code Listing 3: Exception handling procedure as autonomous transaction with COMMIT CREATE OR REPLACE PROCEDURE record_error IS PRAGMA AUTONOMOUS_TRANSACTION; l_code PLS_INTEGER := SQLCODE; l_mesg VARCHAR2(32767) := SQLERRM; BEGIN INSERT INTO error_log You cannot use SQLERRM directly in a SQL statement. This leads to reduced productivity or fewer exception handlers (programmers don’t feel that they have to write all this code, so they rationalize away the need to include a handler). CASE 6: Finally ran case where my unnamed block did some ok inserts, I called a proc that did some more ok updates, then I called a proc that did some Oracle Sql Codes List

How to make your world’s revolutions feel realistic? In TimesTen, these three types of exceptions are used in the same way as in Oracle Database. You may, in addition, want to record values of application-specific data, such as variables or column values. 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

Example 11-6 Anonymous Block Handles ZERO_DIVIDE DECLARE stock_price NUMBER := 9.73; net_earnings NUMBER := 0; pe_ratio NUMBER; BEGIN pe_ratio := stock_price / net_earnings; -- raises ZERO_DIVIDE exception DBMS_OUTPUT.PUT_LINE('Price/earnings ratio = ' Pl Sql Exception Handling Examples 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 The technique is: Encase the transaction in a sub-block.

THEN RAISE past_due; END IF; END; ------------- sub-block ends EXCEPTION ...

You can avoid problems by declaring scalar variables with %TYPE qualifiers and record variables to hold query results with %ROWTYPE qualifiers. I want to... Note that you do not need to qualify raise_application_error with DBMS_STANDARD */ raise_application_error(-20101, 'Expecting at least 1000 tables'); ELSE NULL; -- Do the rest of the processing (for the non-error case). Sqlerror How to improve this plot?

Some common internal exceptions have predefined names, such as ZERO_DIVIDE and STORAGE_ERROR. 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 The best way to pass exception information to the calling function is to do nothing, and let the exception naturally raise. 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.

Normally, just the failed SQL statement is rolled back, not the whole transaction. DUP_VAL_ON_INDEX ORA-00001 -1 Program attempted to insert duplicate values in a column that is constrained by a unique index. Note: Unreachable code could represent a mistake or be intentionally hidden by a debug flag. Exceptions declared in a block are considered local to that block and global to all its sub-blocks.

Passing a zero to SQLERRM always returns the message normal, successful completion. An exception name declaration has this syntax: exception_name EXCEPTION; For semantic information, see "Exception Declaration". EXCEPTION WHEN NO_DATA_FOUND THEN INSERT INTO errors VALUES ('Error in statement ' || stmt); END; Copyright © 1996, 2002 Oracle Corporation. If so, do it by making a call to a procedure declared with the PRAGMA AUTONOMOUS_TRANSACTION, so that you can commit your debugging information, even if you roll back the work

Example 11-24 Exception Handler Runs and Execution Continues DECLARE sal_calc NUMBER(8,2); BEGIN INSERT INTO employees_temp (employee_id, salary, commission_pct) VALUES (301, 2500, 0); BEGIN SELECT (salary / commission_pct) INTO sal_calc FROM employees_temp In other words, you cannot resume processing where you left off. IF ... Example 10-13 Retrying a Transaction After an Exception CREATE TABLE results ( res_name VARCHAR(20), res_answer VARCHAR2(3) ); CREATE UNIQUE INDEX res_name_ix ON results (res_name); INSERT INTO results VALUES ('SMYTHE', 'YES'); INSERT

To handle other Oracle errors, you can use the OTHERS handler. The package function DBMS_UTILITY.FORMAT_ERROR_STACK, described in Oracle Database PL/SQL Packages and Types Reference This function returns the full error stack, up to 2000 bytes. Handling Raised PL/SQL Exceptions When an exception is raised, normal execution of your PL/SQL block or subprogram stops and control transfers to its exception-handling part, which is formatted as follows: EXCEPTION TIMEOUT_ON_RESOURCE 00051 -51 A time out occurs while Oracle is waiting for a resource.

Usenet source: Ken Quirici (c.d.o.server - 29-Oct-2004) Basic Exception Handling With Error Basic Block Structure Handling CREATE OR REPLACE PROCEDURE IS BEGIN NULL; EXCEPTION WHEN THEN You can define exceptions of your own in the declarative part of any PL/SQL block, subprogram, or package.
