Example 11-2 Displaying and Setting PLSQL_WARNINGS with DBMS_WARNING Subprograms Disable all warning messages for this session: ALTER SESSION SET PLSQL_WARNINGS='DISABLE:ALL'; With warnings disabled, this procedure compiles with no warnings: CREATE OR 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
Also, it can use the pragma EXCEPTION_INIT to map specific error numbers returned by raise_application_error to exceptions of its own, as the following Pro*C example shows: EXEC SQL EXECUTE /* Execute Note: Unreachable code could represent a mistake or be intentionally hidden by a debug flag. Description 1 This environment variable opens up an output buffer of size limit of 200000. 2 Start of the declaration section of the block. 3 A local variable l_n_salary of the Oracle Raise Exception With Message Home Book List Contents Index Master Index Feedback Go to main content 18/99 The script content on this page is for navigation purposes only and does not alter the content in

PL/SQL supports programmers to catch such conditions using EXCEPTION block in the program and an appropriate action is taken against the error condition. The inner block does not have an exception handler for C, so exception C propagates to the outer block. But system errors could also occur from hardware failures, like the “ORA-12541: TNS: no listener”, when an ftp-server might be unreachable over the network. To see warnings (and errors) generated during compilation, either query the static data dictionary view *_ERRORS (described in Oracle Database Reference) or, in the SQL*Plus environment, use the command SHOW ERRORS. Functions For Error Trapping Are Contained In Which Section Of A Pl/sql Block
END; Omitting the exception name in a RAISE statement--allowed only in an exception handler--reraises the current exception.

So, an exception raised inside a handler propagates immediately to the enclosing block, which is searched to find a handler for the newly raised exception. Our first message tells us a “no data found”-error occurred, our second message tells us we had two errors, first the ORA-01403, followed by the user-defined ORA-20001. The technique is: Encase the transaction in a sub-block. However, an exception name can appear only once in the exception-handling part of a PL/SQL block or subprogram.
Example 11-7 Anonymous Block Avoids ZERO_DIVIDE DECLARE stock_price NUMBER := 9.73; net_earnings NUMBER := 0; pe_ratio NUMBER; BEGIN pe_ratio := CASE net_earnings WHEN 0 THEN NULL ELSE stock_price / net_earnings END; TOO_MANY_ROWS ORA-01422 The SQL INTO statement brought back more than one value or row (only one is allowed).
