Pl Sql Exception Get Error Message
If you neglect to code a check, the error goes undetected and is likely to cause other, seemingly unrelated errors. CASE_NOT_FOUND None of the choices in the WHEN clauses of a CASE statement is selected, and there is no ELSE clause. stmt := 2; -- designates 2nd SELECT statement SELECT ... Handling Exceptions Raised in Declarations Exceptions can be raised in declarations by faulty initialization expressions. http://setiweb.org/pl-sql/pl-sql-error-message-exception.php
Example 11-25 uses the preceding technique to retry a transaction whose INSERT statement raises the predefined exception DUP_VAL_ON_INDEX if the value of res_name is not unique. Example Since EXCEPTION HANDLING is usually written with the following syntax: EXCEPTION WHEN exception_name1 THEN [statements] WHEN exception_name2 THEN [statements] WHEN exception_name_n THEN [statements] WHEN OTHERS THEN [statements] END [procedure_name]; You Thus HandleAll should have been called with p_Top = TRUE. */ PROCEDURE StoreStacks(p_Module IN errors.module%TYPE, p_SeqNum OUT errors.seq_number%TYPE, p_CommitFlag BOOLEAN DEFAULT FALSE); END ErrorPkg; / Error Handling Package Body CREATE OR In TimesTen, these three types of exceptions are used in the same way as in Oracle Database.
Trapping predefined TimesTen errors Trap a predefined TimesTen error by referencing its predefined name in your exception-handling routine. These are known as user-defined exceptions. You cannot return to the current block from an exception handler. ORA-01422 ZERO_DIVIDE When you attempt to divide a number by zero.
Finally, catch the exception and link the exception to a user-defined error number in RAISE_APPLICATION_ERROR. So, a SELECT INTO statement that calls an aggregate function never raises NO_DATA_FOUND. The functions SQLCODE and SQLERRM are especially useful in the OTHERS exception handler because they tell you which internal exception was raised. Example 11-13 Exception that Propagates Beyond Scope is Handled CREATE OR REPLACE PROCEDURE p AUTHID DEFINER AS BEGIN DECLARE past_due EXCEPTION; due_date DATE := trunc(SYSDATE) - 1; todays_date DATE := trunc(SYSDATE);
However, the code block below does not work (I am experiencing a "found / expecting" syntax error) CREATE OR REPLACE PROCEDURE DBP.TESTING_SP AS DECLARE v_code NUMBER; v_errm VARCHAR2(64); BEGIN UPDATE PS_NE_PHONE_TBL Outside an exception handler, you must specify the exception name. Each handler consists of a WHEN clause, which specifies an exception, followed by a sequence of statements to be executed when that exception is raised. Also, if a stored subprogram fails with an unhandled exception, PL/SQL does not roll back database work done by the subprogram.
You can, however, declare the same exception in two different blocks. For more information about EXECUTE IMMEDIATE, refer to "Dynamic SQL in PL/SQL (EXECUTE IMMEDIATE statement)". If earnings are zero, the function DECODE returns a null. The technique is: Encase the transaction in a sub-block.
For example: Command> DECLARE > v_lname VARCHAR2 (15); > BEGIN > SELECT last_name INTO v_lname > FROM employees > WHERE first_name = 'John'; > DBMS_OUTPUT.PUT_LINE ('Last name is :' || v_lname); http://stackoverflow.com/questions/12327643/how-to-catch-and-return-or-print-an-exception-in-an-oracle-pl-sql-create-or-re SUBSCRIPT_BEYOND_COUNT ORA-06533 -6533 A program referenced a nested table or varray using an index number larger than the number of elements in the collection. The maximum length of an Oracle error message is 512 characters including the error code, nested messages, and message inserts such as table and column names. When the sub-block ends, the enclosing block continues to execute at the point where the sub-block ends.
TOO_MANY_ROWS ORA-01422 -1422 Single row SELECT returned multiple rows. http://setiweb.org/pl-sql/pl-sql-exception-error-code.php An exception handler for a named internally defined exception handles that exception whether it is raised implicitly or explicitly. NOT_LOGGED_ON ORA-01012 Database connection lost. SYS_INVALID_ROWID ORA-01410 The conversion of a character string into a universal rowid fails because the character string does not represent a valid rowid.
RAISE_APPLICATION_ERROR is part of package DBMS_STANDARD, and as with package STANDARD, you do not need to qualify references to it. Topics RAISE Statement RAISE_APPLICATION_ERROR Procedure RAISE Statement The RAISE statement explicitly raises an exception. 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 = navigate to this website Redeclaring Predefined Exceptions Remember, PL/SQL declares predefined exceptions globally in package STANDARD, so you need not declare them yourself.
Note: An internally defined exception with a user-declared name is still an internally defined exception, not a user-defined exception. Otherwise, DECODE returns the price-to-earnings ratio. Examples of internally defined exceptions are ORA-00060 (deadlock detected while waiting for resource) and ORA-27102 (out of memory).
ROWTYPE_MISMATCH ORA-06504 -6504 Host cursor variable and PL/SQL cursor variable involved in an assignment statement have incompatible return types.
Home Book List Contents Index Master Index Feedback Go to main content 8/14 4 Errors and Exception Handling This chapter describes the flexible error trapping and error handling you can use In the following example, you declare an exception named past_due: DECLARE past_due EXCEPTION; Exception and variable declarations are similar. Advantages of PL/SQL Exceptions Using exceptions for error handling has several advantages. The general syntax to declare unnamed system exception using EXCEPTION_INIT is: DECLARE exception_name EXCEPTION; PRAGMA EXCEPTION_INIT (exception_name, Err_code); BEGIN Execution section EXCEPTION WHEN exception_name THEN handle the exception END; For Example:
BEGIN p(1); END; / Result: Substituting default value for invalid number. TimesTen implicitly raises the error. If the optional third parameter is TRUE, the error is placed on the stack of previous errors. http://setiweb.org/pl-sql/pl-sql-exception-print-error-message.php SUBSCRIPT_BEYOND_COUNT ORA-06533 Reference to a nested table or varray index higher than the number of elements in the collection.
Because of the size restriction (512 versus 2000 characters), it is recommended that you call DBMS_UTILITY.FORMAT_ERROR_STACK instead of SQLERRM to ensure that you see the full error message string.

Redeclared Predefined Exceptions Oracle recommends against redeclaring predefined exceptions—that is, declaring a user-defined exception name that is a predefined exception name. (For a list of predefined exception names, see Table 11-3.) So either remove line 1 and create an anonymous block, or remove line 2 and create a named procedure." but I'm not sure how to create an anonymous block or create Table 4-1 Predefined exceptions Exception name Oracle Database error number SQLCODE Description ACCESS_INTO_NULL ORA-06530 -6530 Program attempted to assign values to the attributes of an uninitialized object. If no exception has been raised, SQLCODE returns zero and SQLERRM returns the message: ORA-0000: normal, successful completion.
Refer to "Warnings and Errors" in Oracle TimesTen In-Memory Database Error Messages and SNMP Traps for information about specific TimesTen error messages. Code that can never run By setting the compilation parameter PLSQL_WARNINGS, you can: Enable and disable all warnings, one or more categories of warnings, or specific warnings Treat specific warnings as But when the handler completes, the block is terminated. Example 4-2 Using RAISE statement to trap user-defined exception In this example, the department number 500 does not exist, so no rows are updated in the departments table.
To give a name to an internally defined exception, do the following in the declarative part of the appropriate anonymous block, subprogram, or package. (To determine the appropriate block, see "Exception It should be FALSE at other levels. */ PROCEDURE HandleAll(p_Top BOOLEAN); /* Prints the error and call stacks (using DBMS_OUTPUT) for the given module and sequence number. */ PROCEDURE PrintStacks(p_Module IN If the transaction fails, control transfers to the exception-handling part of the sub-block, and after the exception handler runs, the loop repeats. Now consider a TimesTen example where the exception is not handled, again run with autocommit disabled: create table mytable (num int not null primary key); set serveroutput on insert into mytable
That lets you refer to any internal exception by name and to write a specific handler for it.
