Error In Oracle

Churchill 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

Oracle Error 12154
a run-time error such as stack overflow or division by zero stops normal processing and returns control to the operating system. oracle on error continue With PL/SQL, a mechanism called exception handling lets you "bulletproof" your program so that it can continue operating in the presence of errors. This chapter discusses the following topics: Overview of PL/SQL Error Handling https://docs.oracle.com/cd/B28359_01/nav/lookup.htm?id=ERRMG Advantages of PL/SQL Exceptions Predefined PL/SQL Exceptions Defining Your Own PL/SQL Exceptions How PL/SQL Exceptions Are Raised How PL/SQL Exceptions Propagate Reraising a PL/SQL Exception Handling Raised PL/SQL Exceptions Tips for Handling PL/SQL Errors Overview of PL/SQL Error Handling In PL/SQL, a warning or error condition is called an exception. Exceptions can be internally defined (by the run-time system) or user defined. Examples of internally defined exceptions include https://docs.oracle.com/cd/B10500_01/appdev.920/a96624/07_errs.htm 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. Internal exceptions are raised implicitly (automatically) by the run-time system. User-defined exceptions must be raised explicitly by RAISE statements, which can also raise predefined exceptions. 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. In the example below, you calculate and store a price-to-earnings ratio for a company with ticker symbol XYZ. If the company has zero earnings, the predefined exception ZERO_DIVIDE is raised. This stops normal execution of the block and transfers control to the ex

industry long enough to remember the bad old days, when every developer and DBA had a pile of dusty Oracle user guides on their desks and, every time their database or application coughed up an error, would thumb through the books with mounting desperation. Fortunately, the times have moved on and we now all outsource our memories to Google and Bing and Baidu. Our desks are clear, but our need for external help whenever we are ambushed by unexpected errors is just as strong. Using tools Google have made available, I have put together a list of the ORA messages we collectively searched for the most in the first month of 2012. These messages (see a Billboard-style Top 40 Chart at the bottom of this article) are a mix of those generic errors that can mean pretty much anything, the error messages we see most rarely, and those common error numbers that we never seem able to memorise. ORA-12154: TNS:could not resolve the connect identifier specified (#1) Coming in at number 1, and googled more than twice as often as any other error message, this error is, almost appropriately, often the very first one you get on trying to establish a connection to your database. Simply put, it means that you have named the database you wish to be connected to and Oracle doesn’t know who the heck you’re talking about. This error is often caused by typos, maybe in your connection string, but possibly in your tnsnames.ora file. It is also possible that the tnsnames.ora file is not accessible or does not even exist. If it does, ensure that it contains the service name you are using; also go over it with a fine toothcomb to make sure it doesn’t have any unpaired parentheses or such. ORA-00600: internal error code, arguments: [%s], [%s],[%s], [%s], [%s] (#2) Coming in at number 2 is a generic error; it means something serious has gone wrong and you are going to need to roll up your sleeves, dig in, and find out what. But you are not without clues. Your alert.log file will contain the path to your trace file. You will want to look in it, as a record is written to the trace file every time an ORA-00600 error occurs. Take the information you get from your trace file and the first argument in the square brackets (the internal message number), and head over to My Oracle Support (Metalink). There you will find a handy ORA-0600 lookup tool (Note 153788.1) that will direct you to additional information that will help you solve your problem. ORA-1722: Invalid Number (#3) You get this error when your SQL tries to convert a non-numeric string into a nu
