How To Trace The Execution Of A Stored Procedure In Oracle
oracle 10g? up vote 3 down vote favorite 2 I need an example of creating error log file for stored procedure in oracle. please give me an example with table creation and stored procedure creation and error log creation. Thanks in advance EDIT (relevant info from other question) Suppose there is a stored procedure. When I am executing that stored procedure, some expected error/exception may occur, so sql stored procedure logging I need to create an error log table in which all the errors will automatically be store whenever I will execute the stored procedure. For example, if there is some column which does not allow null values, but the user is entering null values, then that error should be generated and it should stored in the error log table. oracle stored-procedures logging oracle10g share|improve this question edited Nov 14 '10 at 8:01 Jeffrey Kemp 37k859104 asked Nov 13 '10 at 10:05 puspanjali 1612 See also this answer to a similar question –Tony Andrews Jul 6 '11 at 11:05 add a comment| 2 Answers 2 active oldest votes up vote 5 down vote You haven't really given a lot of detail about your requirements. Here is a simple error log table and a procedure to log error messages into it: CREATE TABLE error_log (ts TIMESTAMP NOT NULL, msg VARCHAR2(4000)); CREATE PROCEDURE log_error (msg IN VARCHAR2) IS BEGIN INSERT INTO error_log (ts, msg) VALUES (SYSTIMESTAMP, SUBSTR(insert_log.msg, 1, 4000)); END log_error; You might or might not need it to be an autonomous transaction. That would depend on whether you want the log to record errors from procedures that rollback their changes. Typicall

Oracle Exception Handling
By Steven Feuerstein Part 6 in a series of articles on understanding and using PL/SQL Even dbms_utility if you write absolutely perfect PL/SQL programs, it is possible and even likely that something will go wrong and an error will occur when those programs are run. http://stackoverflow.com/questions/4171955/how-to-create-error-log-for-stored-procedure-in-oracle-10g How your code responds to and deals with that error often spells the difference between a successful application and one that creates all sorts of problems for users as well as developers. This article explores the world of error management in PL/SQL: the different types of exceptions you may encounter; when, why, and how exceptions are http://www.oracle.com/technetwork/issue-archive/2012/12-mar/o22plsql-1518275.html raised; how to define your own exceptions; how you can handle exceptions when they occur; and how you can report information about problems back to your users. Exception Overview There are three categories of exceptions in the world of PL/SQL: internally defined, predefined, and user-defined. An internally defined exception is one that is raised internally by an Oracle Database process; this kind of exception always has an error code but does not have a name unless it is assigned one by PL/SQL or your own code. An example of an internally defined exception is ORA-00060 (deadlock detected while waiting for resource). A predefined exception is an internally defined exception that is assigned a name by PL/SQL. Most predefined exceptions are defined in the STANDARD package (a package provided by Oracle Database that defines many common programming elements of the PL/SQL language) and are among the most commonly encountered exceptions. One example is ORA-00001, which is assigned the name DUP_VAL_ON_INDEX in PL/SQL and is raised when a uni

An exception can be either internally defined (by the run-time stored procedure 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 predefined names, such as ZERO_DIVIDE and STORAGE_ERROR. The other internal exceptions can be given names. You can define your own exceptions in the declarative part of any PL/SQL block, subprogram, or package. For example, oracle stored procedure 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 environment. For information about managing errors when using BULK COLLECT, see Handling FORALL Exceptions (%BULK_EXCEPTIONS Attribute). Example 11-1 calculates a price-to-earnings ratio for a company. If the company has zero earnings, the division operation raises the predefined exception ZERO_DIVIDE, the execution of the block is interrupted, and control is transferred to the exception handlers. The optional OTHERS handler catches all exceptions that the block does not name sp
