Movie about a board-game that asks the players touchy questions How do I replace and (&&) in a for loop? You cannot return to the current block from an exception handler.
A PL/SQL block cannot catch an exception raised by a remote subprogram. Example 11-6 Using RAISE to Raise a User-Defined Exception DECLARE out_of_stock EXCEPTION; number_on_hand NUMBER := 0; BEGIN IF number_on_hand < 1 THEN RAISE out_of_stock; -- raise an exception that you defined You can also treat particular messages as errors instead of warnings. Pl Sql Exception When Others The functions SQLCODE and SQLERRM are especially useful in the OTHERS exception handler because they tell you which internal exception was raised.
Summary of Predefined PL/SQL Exceptions An internal exception is raised automatically if your PL/SQL program violates an Oracle rule or exceeds a system-dependent limit. Pl Sql Exception Handling Examples Place the statement in its own sub-block with its own exception handlers. Thanks WHILE indx IS NOT NULL LOOP table_dump_csv(tableList(indx), tableList(indx) || '.csv'); indx := tableList.NEXT(indx); END LOOP; oracle plsql share|improve this question edited Nov 27 '08 at 12:39 toolkit 34.9k1179123 asked Nov https://docs.oracle.com/cd/B19306_01/server.102/b14357/ch12052.htm For example, in the following procedure, the NO_DATA_FOUND exception is handled directly, while all other exceptions are raised to the calling block: CREATE OR REPLACE PROCEDURE MY_PROCEDURE() IS BEGIN do_stuff(); EXCEPTION
Thesis reviewer requests update to literature review to incorporate last four years of research. Functions For Error Trapping Are Contained In Which Section Of A Pl/sql Block SQL> 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. Sometimes the error is not immediately obvious, and cannot be detected until later when you perform calculations using bad data. For internal exceptions, SQLCODE returns the number of the Oracle error.

Some common internal exceptions have predefined names, such as ZERO_DIVIDE and STORAGE_ERROR.
PL/SQL predefines some common Oracle errors as exceptions.
WHILE indx IS NOT NULL LOOP BEGIN table_dump_csv(tableList(indx), tableList(indx) || '.csv'); EXCEPTION WHEN OTHERS THEN -- Handle/Ignore the exception as appropriate END; indx := tableList.NEXT(indx); END LOOP; Alternatively you could change LOGIN_DENIED 01017 -1017 A program attempts to log on to the database with an invalid username or password.

CONTINUE Turns off the EXIT option. my review here That way, you can report errors to your application and avoid returning unhandled exceptions.
For example, here is a procedure with unnecessary code that could be removed. However, the same scope rules apply to variables and exceptions. To reraise an exception, use a RAISE statement without an exception name, which is allowed only in an exception handler: DECLARE salary_too_high EXCEPTION; current_salary NUMBER := 20000; max_salary NUMBER := 10000; I'm getting a ORA-06550 & PLS-00201 identifer CONTINUE must be declared DECLARE v_attr char(88); CURSOR SELECT_USERS IS SELECT id FROM USER_TABLE WHERE USERTYPE = 'X'; BEGIN FOR user_rec IN SELECT_USERS LOOP

Text above line in TikZ probability tree Human vs apes: What advantages do humans have over apes? 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.
In the following example, the INSERT statement might raise an exception because of a duplicate value in a unique column. This handler is never called. Thus, a block or subprogram can have only one OTHERS handler.
