Raise Application Error In Oracle Function
For example, you might want to roll back a transaction in the current block, then log the error in an enclosing block. Unhandled exceptions can also affect subprograms. Steps to be followed to use user-defined exceptions: • They should be explicitly declared in the declaration section. • They should be explicitly raised in the Execution Section. • They should Special discounts should be provided. http://vealcine.com/error-in/raise-application-error-in-oracle-with-example.php
Without exception handling, every time you issue a command, you must check for execution errors: BEGIN SELECT ... -- check for 'no data found' error SELECT ... -- check for 'no An error message causes the compilation to fail. The FETCH statement is expected to return no rows eventually, so when that happens, no exception is raised. 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
Difference Between Raise And Raise_application_error In Oracle
Raising Exceptions with the RAISE Statement PL/SQL blocks and subprograms should raise an exception only when an error makes it undesirable or impossible to finish processing. Declaring PL/SQL Exceptions Exceptions can be declared only in the declarative part of a PL/SQL block, subprogram, or package. 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. But nicely put together.
With many programming languages, unless you disable error checking, a run-time error such as stack overflow or division by zero stops normal processing and returns control to the operating system. share|improve this answer edited Nov 19 '09 at 10:39 answered Nov 19 '09 at 7:11 APC 87.4k1384184 +1 Very explanatory.

unless you used the pragma EXCEPTION_INIT to associate the exception name with an Oracle error number, in which case SQLCODE returns that error number and SQLERRM returns the corresponding error message. b) to make the user-defined exception look like an Oracle error. Difference Between Raise And Raise_application_error In Oracle To have the enclosing block handle the raised exception, you must remove its declaration from the sub-block or define an OTHERS handler. Oracle Raise DECLARE pe_ratio NUMBER(3,1); BEGIN SELECT price / earnings INTO pe_ratio FROM stocks WHERE symbol = 'XYZ'; -- might cause division-by-zero error INSERT INTO stats (symbol, ratio) VALUES ('XYZ', pe_ratio); COMMIT; EXCEPTION
SUBSCRIPT_BEYOND_COUNT Your program references a nested table or varray element using an index number larger than the number of elements in the collection. get redirected here AKA: Comment tersely with value-added information. To have the enclosing block handle the raised exception, you must remove its declaration from the sub-block or define an OTHERS handler. In other words, you cannot resume processing where you left off. Raise_application_error Parameters
Also, if a stored subprogram fails with an unhandled exception, PL/SQL does not roll back database work done by the subprogram. From there on, the exception propagates normally. For example, in the Oracle Precompilers environment, any database changes made by a failed SQL statement or PL/SQL block are rolled back. navigate to this website Not the answer you're looking for?
Example Since EXCEPTION HANDLING is usually written with the following syntax: EXCEPTION WHEN exception_name1 THEN [statements] WHEN exception_name2 THEN [statements] WHEN exception_name_n THEN [statements] WHEN OTHERS THEN [statements] END [procedure_name]; You Raise_application_error In Oracle 11g That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram.

Exceptions cannot propagate across remote procedure calls done through database links.
