How can I copy and paste text lines across different files in a bash script? 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. All rights reserved. Example 11-1 Run-Time Error Handling DECLARE stock_price NUMBER := 9.73; net_earnings NUMBER := 0; pe_ratio NUMBER; BEGIN -- Calculation might cause division-by-zero error.

How can I compute the size of my Linux install + all my applications?

Thus, a block or subprogram can have only one OTHERS handler. asked 1 year ago viewed 13430 times active 4 months ago Linked 1 On error resume next type of error handling in PL/SQL oracle Related 1274Catch multiple exceptions at once?798Manually raising Look at that other question, maybe you can just use GOTO. –angus May 5 '11 at 20:21 2 A simpler solution would be to loop through a query that joins Newark Airport to central New Jersey on a student's budget Does a regular expression model the empty language if it contains symbols not in the alphabet?

END; You can still handle an exception for a statement, then continue with the next statement. For example, when an open host cursor variable is passed to a stored subprogram, the return types of the actual and formal parameters must be compatible. l_number := l_number + 1; END IF; END LOOP; DBMS_OUTPUT.put_line('IF : ' || l_number); l_number := 0; FOR i IN 1 .. 100 LOOP IF MOD(i,2) = 0 THEN GOTO label_continue; As part of the migration, I'm working on a script which inserts the data into tables that are used by the app.

Tips for Handling PL/SQL Errors In this section, you learn three techniques that increase flexibility.

User-defined exceptions must be raised explicitly by RAISE statements, which can also raise predefined exceptions. Reduce function is not showing all the roots of a transcendental equation Why don't browser DNS caches mitigate DDOS attacks on DNS providers? WHEN OTHERS THEN -- optional handler for all other errors sequence_of_statements3 END; To catch raised exceptions, you write exception handlers. However, when an exception is raised inside a cursor FOR loop, the cursor is closed implicitly before the handler is invoked.

User-defined exceptions must be raised explicitly by RAISE statements or invocations of the procedure DBMS_STANDARD.RAISE_APPLICATION_ERROR. This stops normal execution of the block and transfers control to the exception handlers. You declare an exception by introducing its name, followed by the keyword EXCEPTION. With exceptions, you can reliably handle potential errors from many statements with a single exception handler: BEGIN SELECT ...

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 A program attempts to divide 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. The FETCH statement is expected to return no rows eventually, so when that happens, no exception is raised. If the optional third parameter is TRUE, the error is placed on the stack of previous errors.

To start viewing messages, select the forum that you want to visit from the selection below. See Also: Example 5-38, "Collection Exceptions" 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 For a workaround, see Defining Your Own Error Messages (RAISE_APPLICATION_ERROR Procedure). Retrying a Transaction After an exception is raised, rather than abandon your transaction, you might want to retry it.

For user-defined exceptions, SQLCODE returns +1 and SQLERRM returns the message: User-Defined Exception. SET SERVEROUTPUT ON DECLARE ex_continue EXCEPTION; l_number NUMBER := 0; BEGIN FOR i IN 1 .. 100 LOOP BEGIN IF MOD(i,2) != 0 THEN RAISE ex_continue; END IF; -- Do something That way, an exception handler written for the predefined exception can process other errors, as the following example shows: DECLARE acct_type INTEGER := 7; BEGIN IF acct_type NOT IN (1, 2, The usual scoping rules for PL/SQL variables apply, so you can reference local and global variables in an exception handler.

The optional OTHERS exception handler, which is always the last handler in a block or subprogram, acts as the handler for all exceptions not named specifically. You can also use this package when compiling a complex application, made up of several nested SQL*Plus scripts, where different warning settings apply to different subprograms. If you exit a subprogram successfully, PL/SQL assigns values to OUT parameters. You can suppress or display groups of similar warnings during compilation.

This parameter can be set at the system level or the session level. CURSOR_ALREADY_OPEN 06511 -6511 A program attempts to open an already open cursor. To invoke RAISE_APPLICATION_ERROR, use the following 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 DUP_VAL_ON_INDEX 00001 -1 A program attempts to store duplicate values in a column that is constrained by a unique index.

Why did they bring C3PO to Jabba's palace and other dangerous missions? Once you know the error code, you can use it with pragma EXCEPTION_INIT and write a handler specifically for that error. That is, the exception reproduces itself in successive enclosing blocks until a handler is found or there are no more blocks to search. The optional OTHERS exception handler, which is always the last handler in a block or subprogram, acts as the handler for all exceptions not named specifically.

Exceptions can be internally defined (by the runtime system) or user defined. Unhandled exceptions can also affect subprograms. Unlike variables, exceptions cannot appear in assignment statements or SQL statements. However, exceptions cannot propagate across remote procedure calls (RPCs).

To reraise an exception, simply place a RAISE statement in the local handler, as shown in the following example: DECLARE out_of_balance EXCEPTION; BEGIN ...

THEN -- handle the error WHEN OTHERS THEN -- handle all other errors END; If you want two or more exceptions to execute the same sequence of statements, list the exception It can be used on its own, or as part of a CONTINUE WHEN statement, as shown below. You declare an exception by introducing its name, followed by the keyword EXCEPTION. However, other user-defined exceptions must be raised explicitly by RAISE statements.

Within this handler, you can call the functions SQLCODE and SQLERRM to return the Oracle error code and message text. If the INSERT succeeds, exit from the loop immediately. Handling Exceptions Raised in Declarations Exceptions can be raised in declarations by faulty initialization expressions.
