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. With PL/SQL, oracle predefined exceptions a mechanism called exception handling lets you "bulletproof" your program so that it can continue operating in the presence of errors.

Exceptions can be internally defined (by the runtime system) or user defined. Examples of internally defined exceptions include division by zero and out of memory. Some common internal exceptions have predefined names, such as ZERO_DIVIDE and STORAGE_ERROR. The other internal exceptions can be given names. You can define exceptions of your own in the declarative part of any PL/SQL block, subprogram, or package. For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. Unlike internal exceptions, user-defined exceptions must be given names. When an error occurs, an exception is raised. That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram.

An exception can be either internally defined (by the run-time system) or user-defined. Examples of internally defined exceptions are ORA-22056 (value string is divided by zero) and ORA-27102 (out of memory). Some common internal exceptions have https://docs.oracle.com/cd/B28359_01/appdev.111/b28370/errors.htm predefined names, such as ZERO_DIVIDE and STORAGE_ERROR.

For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. User-defined exceptions must be given names. When an error occurs, an exception is raised. That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram. Internal exceptions are raised implicitly (automatically) by the run-time system. User-defined exceptions must be raised explicitly by RAISE statements or invocations of the procedure DBMS_STANDARD.RAISE_APPLICATION_ERROR. To handle raised exceptions, you write separate routines called exception handlers. After an exception handler runs, the current block stops executing and the enclosing block resumes with the next statement. If there is no enclosing block, control returns to the host env

Description When you encounter an ORA-06502 error, the following error message will appear: ORA-06502: PL/SQL: numeric or value error Cause You tried to execute a statement that resulted in an arithmetic, numeric, string, conversion, or constraint error. The common reasons for this error are: You tried to assign a value to a numeric variable, but the value oracle error variables is larger than the variable can handle. You tried to assign a non-numeric value to a numeric variable and caused a conversion error. Resolution Let's look at three options on how to resolve the ORA-06502 error: Option #1 - Value too large In our first option, this error occurs when you try to assign a value to a numeric variable, but the value is larger than the variable can handle. For example, if you created a procedure called TestProc as follows: SQL> CREATE OR REPLACE PROCEDURE TestProc 2 AS 3 v_number number(2); 4 BEGIN 5 v_number := 100; 6 END; 7 / Procedure created. This procedure was successfully created. But when we try to execute this procedure, we will get an ORA-06502 error as follows: SQL> execute TestProc(); BEGIN TestProc(); END; * ERROR at line 1: ORA-06502: PL/SQL: numeric or value error: number precision too large ORA-06512: at "EXAMPLE.TESTPROC", line 5 ORA-06512: at line 1 The first line of the error message (ie: ORA-06502) indicates the error that occurred, while the second line of the error message (ie: ORA-06512) indicates that the error occurred at line 5 of the PLSQL code. In this example, you've tried to assign a 3 digit number to a variable called v_number
