In that case, change the value that must be unique and continue with the next loop iteration. Topics: Overview of PL/SQL Run-Time Error Handling Guidelines for Avoiding and Handling PL/SQL Errors and Exceptions Advantages of PL/SQL Exceptions Predefined PL/SQL Exceptions Defining Your Own PL/SQL Exceptions How PL/SQL Exceptions Exceptions cannot propagate across remote procedure calls done through database links. For user-defined exceptions, SQLCODE returns +1 and SQLERRM returns the message: User-Defined Exception. click site

In the above example, a trigger has been created in the schema A to stop any modification to the EMPLOYEES table's data during the weekend. IF ... BEGIN 6. The raise_application_error will also populate the SQL errors codes so that they can be programmatically handled. ================================================== The built in procedure RAISE_APPLICATION_ERROR in the DBMS_STANDARD package can be used for displaying

Oracle Raise

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. Exceptions Raised in Declarations Exceptions can be raised in declarations by faulty initialization expressions. Therefore, the values of explicit cursor attributes are not available in the handler.

WHEN OTHERS THEN -- optional handler for all other errors sequence_of_statements3 END; To catch raised exceptions, you write exception handlers. In other words, you cannot resume processing where you left off. If you redeclare a global exception in a sub-block, the local declaration prevails. Raise Application Error In Oracle Triggers If you redeclare a global exception in a sub-block, the local declaration prevails.

EXCEPTION 12. Difference Between Raise And Raise_application_error In Oracle Advantages of PL/SQL Exceptions Using exceptions for error handling has several advantages. Scope Rules for PL/SQL Exceptions You cannot declare an exception twice in the same block. See also Example 5-38, "Collection Exceptions".

To handle unexpected Oracle Database errors, you can use the OTHERS handler. Raise_application_error Sqlerrm SELECT ... ... 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 INVALID_NUMBER 01722 -1722 n 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

Difference Between Raise And Raise_application_error In Oracle

In the below example, the employee, whose salary is more than 10000 will be facing an exception which is handled explicitly in the WHEN clause using the user defined exception name. up vote 13 down vote favorite 5 We can use RAISE to fire an exception. Oracle Raise For user-defined exceptions, SQLCODE returns +1 and SQLERRM returns the message User-Defined Exception unless you used the pragma EXCEPTION_INIT to associate the exception name with an Oracle error number, in which Raise_application_error(-20001 However, if you exit with an unhandled exception, PL/SQL does not assign values to OUT parameters (unless they are NOCOPY parameters).

IF l_n_salary>10000 THEN 9. http://vealcine.com/error-in/raise-application-error-in-oracle-pl-sql.php Example 11-3 Scope of PL/SQL Exceptions DECLARE past_due EXCEPTION; acct_num NUMBER; BEGIN DECLARE ---------- sub-block begins past_due EXCEPTION; -- this declaration prevails acct_num NUMBER; due_date DATE := SYSDATE - 1; todays_date When an error occurs, an exception is raised. Unlike internal exceptions, user-defined exceptions must be given names. Raise_application_error Parameters

For example, PL/SQL raises the predefined exception NO_DATA_FOUND if a SELECT INTO statement returns no rows. 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 ... l_n_salary NUMBER; 4. navigate to this website In the following example, you call raise_application_error if an employee's salary is missing: CREATE PROCEDURE raise_salary (emp_id NUMBER, amount NUMBER) AS curr_sal NUMBER; BEGIN SELECT sal INTO curr_sal FROM emp WHERE

With exceptions, you can reliably handle potential errors from many statements with a single exception handler, as in Example 11-2. Explain Different Looping Statement In Pl/sql For example, the declaration in Example 11-10 raises an exception because the constant credit_limit cannot store numbers larger than 999. The raise_application_error will also populate the SQL errors codes so that they can be programmatically handled. ================================================== The built in procedure RAISE_APPLICATION_ERROR in the DBMS_STANDARD package can be used for displaying

Make sure you pass negative error numbers to SQLERRM.

DBMS_OUTPUT.PUT_LINE('Can''t handle an exception in a declaration.'); END; / Handlers in the current block cannot catch the raised exception because an exception raised in a declaration propagates immediately to the enclosing Execution of the handler is complete, so the sub-block terminates, and execution continues with the INSERT statement. They might point out something in the subprogram that produces an undefined result or might create a performance problem. Difference Between Pragma Exception_init And Raise_application_error However, an exception name can appear only once in the exception-handling part of a PL/SQL block or subprogram.

EXCEPTION WHEN OTHERS THEN err_num := SQLCODE; err_msg := SUBSTR(SQLERRM, 1, 100); INSERT INTO errors VALUES (err_num, err_msg); END; The string function SUBSTR ensures that a VALUE_ERROR exception (for truncation) is share|improve this answer edited Nov 19 '09 at 3:06 answered Nov 19 '09 at 3:00 Henry Gao 2,87111315 add a comment| Your Answer draft saved draft discarded Sign up or PL/SQL Warning Categories PL/SQL warning messages are divided into categories, so that you can suppress or display groups of similar warnings during compilation. http://vealcine.com/error-in/raise-application-error-in-oracle-with-example.php If you want two or more exceptions to execute the same sequence of statements, list the exception names in the WHEN clause, separating them by the keyword OR, as follows: EXCEPTION

NOT_LOGGED_ON 01012 -1012 A program issues a database call without being connected to Oracle. Catching Unhandled Exceptions Remember, if it cannot find a handler for a raised exception, PL/SQL returns an unhandled exception error to the host environment, which determines the outcome. Instead, you must assign their values to local variables, then use the variables in the SQL statement, as shown in Example 10-11. The built-in parameter SELF points to the object, and is always the first parameter passed to a MEMBER method.

That way, you can report errors to your application and avoid returning unhandled exceptions. END; In this example, if the SELECT INTO statement raises a ZERO_DIVIDE exception, the local handler catches it and sets pe_ratio to zero. TIMEOUT_ON_RESOURCE A time-out occurs while Oracle is waiting for a resource. If you must know which statement failed, you can use a locator variable, as in Example 11-14.

DECLARE name VARCHAR2(20); ans1 VARCHAR2(3); ans2 VARCHAR2(3); ans3 VARCHAR2(3); suffix NUMBER := 1; BEGIN ... With PL/SQL, a mechanism called exception handling lets you "bulletproof" your program so that it can continue operating in the presence of errors. Again, a single exception handler can trap all division-by-zero errors, bad array subscripts, and so on. Execution of the handler is complete, so the sub-block terminates, and execution continues with the INSERT statement.

When your mind reviews past events Intersection of N lists, or of an N-d array Can I use my client's GPL software? SUBSCRIPT_OUTSIDE_LIMIT 06532 -6532 A program references a nested table or varray element using an index number (-1 for example) that is outside the legal range. Feel free to ask questions on our Oracle forum. INVALID_NUMBER 01722 -1722 n 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

Exceptions declared in a block are considered local to that block and global to all its sub-blocks. In the below example, the employee, whose salary is more than 10000 will be facing an exception which is handled explicitly in the WHEN clause using the user defined exception name. But when the handler completes, the block is terminated. The usual scoping rules for PL/SQL variables apply, so you can reference local and global variables in an exception handler.
