Oracle Exception Error Message Its Not Valid

In Oracle 12.2 and newer you don't have to create a function, you can use the DEFAULT ON CONVERSION ERROR clause in TO_DATE function.

The inner block raises the exception, and its exception handler does the initial handling and then reraises the exception, passing it to the outer block for further handling.

Run-time errors arise from design faults, coding mistakes, hardware failures, and many other sources. Although you cannot anticipate all possible errors, you can plan to handle certain kinds of errors meaningful to your PLSQL program.

Every exception has an error code and an error message associated with it. Oracle Database provides functions for retrieving these values when you are handling an exception see Table 1.

This sometimes surprises a developer new to PLSQL. The exception section of a PLSQL block can only possibly handle an exception raised in the executable section. An exception raised in the declaration section in an attempt to assign a default value to a variable or constant always propagates out unhandled to the enclosing block.

In an exception handler, you can use the built-in functions SQLCODE and SQLERRM to find out which error occurred and to get the associated error message. For internal exceptions, SQLCODE returns the number of the Oracle error.

This tutorial shows you how to deal with PLSQL exception such as declaring user-defined exception, raising an exception and handling it.

The quotORA-01843 not a valid monthquot error is quite common for Oracle SQL developers, and can be fixed in a few ways.

WHERE REPORTS.PID61 The derived table part of the query runs, but when I run the entire query I get an error quotnot a valid monthquot. Why is this? In order to help debug this if I run the following query select rep_date, rep_time from reports where pid61 and rownum1 I get Rep_Date 01042009 Rep_Time 01011753 130000

A predefined exception is an internally defined exception that is assigned a name by PLSQL. Most predefined exceptions are defined in the STANDARD package a package provided by Oracle Database that defines many common programming elements of the PLSQL language and are among the most commonly encountered exceptions.
