Why do jet engines smoke? However, the loop counter increment (or decrement) must be 1. See EXIT for more information. In that specific context, RAISE_APPLICATION_ERROR() does the job. –Frosty Z Jan 18 '12 at 10:40 add a comment| 4 Answers 4 active oldest votes up vote 5 down vote accepted Based http://back2cloud.com/pl-sql/pl-sql-exit-with-error.php

All that I can tell is that I'm using Navicat, using the "query" pane and load my script file into it. up vote 7 down vote favorite 1 I'm trying to do some checkings on a DB schema at the beginning of a PL/SQL script. As the next example shows, the sequence of statements is executed once for each integer in the range. http://stackoverflow.com/questions/21786763/exit-execution-when-error-occurs-pl-sql
CONTINUE Turns off the EXIT option. These conditions are not serious enough to produce an error and keep you from compiling a subprogram. For example, in the Oracle Precompilers environment, any database changes made by a failed SQL statement or PL/SQL block are rolled back.
IF ... What to do with my pre-teen daughter who has been out of control since a severe accident? NONE Directs SQL*Plus to take no action before continuing. Whenever Sqlerror Exit 1 Shell Script That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram.
If you neglect to code a check, the error goes undetected and is likely to cause other, seemingly unrelated errors. Pl/sql Continue After Exception The value it yields can have any PL/SQL datatype other than BLOB, BFILE, an object type, a PL/SQL record, an index-by-table, a varray, or a nested table. You can define your own exceptions in the declarative part of any PL/SQL block, subprogram, or package. their explanation With exceptions, you can handle errors conveniently without the need to code multiple checks, as follows: BEGIN SELECT ...
DECLARE name VARCHAR2(20); ans1 VARCHAR2(3); ans2 VARCHAR2(3); ans3 VARCHAR2(3); suffix NUMBER := 1; BEGIN ... Pl Sql Exit Script SELECT sal INTO salary FROM emp WHERE ... For example, if you declare an exception named invalid_number and then PL/SQL raises the predefined exception INVALID_NUMBER internally, a handler written for INVALID_NUMBER will not catch the internal exception. The structure of PL/SQL is such that the GOTO statement is seldom needed.
For internal exceptions, SQLCODE returns the number of the Oracle error. https://docs.oracle.com/cd/B19306_01/server.102/b14357/ch12052.htm WHEN OTHERS THEN -- optional handler sequence_of_statements3 END; To catch raised exceptions, you write exception handlers. Whenever Sqlerror Exit Thesis reviewer requests update to literature review to incorporate last four years of research. Pl Sql Developer Stop Execution The third form of IF statement uses the keyword ELSIF (not ELSEIF) to introduce additional conditions, as follows: IF condition1 THEN sequence_of_statements1 ELSIF condition2 THEN sequence_of_statements2 ELSE sequence_of_statements3 END IF; If
An exception raised inside a handler propagates immediately to the enclosing block, which is searched to find a handler for this new exception. SYS_INVALID_ROWID The conversion of a character string into a universal rowid fails because the character string does not represent a valid rowid. TIMEOUT_ON_RESOURCE A time-out occurs while Oracle is CURSOR_ALREADY_OPEN 06511 -6511 A program attempts to open an already open cursor. Just add an exception handler to your PL/SQL block. Exception Handling In Oracle Stored Procedure Example
pe_ratio := stock_price / net_earnings; dbms_output.put_line('Price/earnings ratio = ' || pe_ratio); EXCEPTION -- exception handlers begin -- Only one of the WHEN blocks is executed. Figure 11-1, Figure 11-2, and Figure 11-3 illustrate the basic propagation rules. 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. Get More Info So, a SELECT INTO statement that calls an aggregate function never raises NO_DATA_FOUND.
This chapter contains these topics: Overview of PL/SQL Runtime Error Handling Advantages of PL/SQL Exceptions Summary of Predefined PL/SQL Exceptions Defining Your Own PL/SQL Exceptions How PL/SQL Exceptions Are Raised How Sqlplus Exit Command Example 11-4 Using PRAGMA EXCEPTION_INIT DECLARE deadlock_detected EXCEPTION; PRAGMA EXCEPTION_INIT(deadlock_detected, -60); BEGIN NULL; -- Some operation that causes an ORA-00060 error EXCEPTION WHEN deadlock_detected THEN NULL; -- handle the error END; The optional OTHERS handler catches all exceptions that the block does not name specifically.
Simply label the enclosing loop that you want to complete. Examples of internally defined exceptions include division by zero and out of memory. 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 ...

Errors can also occur at other times, for example if a hardware failure with disk storage or memory causes a problem that has nothing to do with your code; but your TOO_MANY_ROWS 01422 -1422 A SELECT INTO statement returns more than one row. Searched CASE Statement PL/SQL also provides a searched CASE statement, which has the form: [<
But when the handler completes, the block is terminated. In other words, you cannot resume processing where you left off. You can place RAISE statements for a given exception anywhere within the scope of that exception. END LOOP; | END LOOP; FOR-LOOP Whereas the number of iterations through a WHILE loop is unknown until the loop completes, the number of iterations through a FOR loop is known
To work with PL/SQL warning messages, you use the PLSQL_WARNINGS compilation parameter, the DBMS_WARNING package, and the static data dictionary views *_PLSQL_OBJECT_SETTINGS. The built-in parameter SELF points to the object, and is always the first parameter passed to a MEMBER method. STORAGE_ERROR PL/SQL runs out of memory or memory has been Consider the following example: DECLARE pe_ratio NUMBER(3,1); BEGIN DELETE FROM stats WHERE symbol = 'XYZ'; BEGIN ---------- sub-block begins SELECT price / NVL(earnings, 0) INTO pe_ratio FROM stocks WHERE symbol = COMMIT Directs SQL*Plus to execute a COMMIT before exiting or continuing and save pending changes to the database.
In the following example, you declare an exception named past_due: DECLARE past_due EXCEPTION; Exception and variable declarations are similar.
