Raise Application Error Errorlevel
The technique is: Encase the transaction in a sub-block. 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. An error message causes the compilation to fail. The type specifications used in RAISERROR message strings map to Transact-SQL data types, while the specifications used in printf map to C language data types. have a peek at this web-site
RAISERROR ('Error raised in TRY block.', -- Message text. 16, -- Severity. 1 -- State. ); END TRY BEGIN CATCH DECLARE @ErrorMessage NVARCHAR(4000); DECLARE @ErrorSeverity INT; DECLARE @ErrorState INT; SELECT @ErrorMessage Using the DBMS_WARNING Package If you are writing a development environment that compiles PL/SQL subprograms, you can control PL/SQL warning messages by calling subprograms in the DBMS_WARNING package. SomeFile.exe IF %ERRORLEVEL% EQU 9009 ( ECHO error - SomeFile.exe not found in your PATH ) It’s hard to know this stuff upfront – I generally just use trial and error Trouble is the recommend method assumes you're backing up one database; but I've overcome that hurdle.

Exit status As you recall from previous lessons, every well-written program returns an exit status when it finishes. SYS_INVALID_ROWID 01410 -1410 The conversion of a character string into a universal rowid fails because the character string does not represent a valid rowid. errline The fourth parameter is optional, errline, which contains the line number the error was raised at, as an integer.

This handler is never called. Incorrect Syntax Near Throw Specify a severity of 10 or lower to use RAISERROR to return a message from a TRY block without invoking the CATCH block.Typically, successive arguments replace successive conversion specifications; the first You might turn on all warnings during development, turn off all warnings when deploying for production, or turn on some warnings when working on a particular subprogram where you are concerned Severity levels less than 0 are interpreted as 0.

Source How many spells can a cleric learn?
Add error-checking code whenever you can predict that an error might occur if your code gets bad input data. Incorrect Syntax Near Raiseerror To have the enclosing block handle the raised exception, you must remove its declaration from the sub-block or define an OTHERS handler. That is, the program's ability to handle situations in which something goes wrong.
An error exit function Since we will be checking for errors often in our programs, it makes sense to write a function that will display error messages.
You can use the pragma EXCEPTION_INIT to associate exception names with other Oracle error codes that you can anticipate. Most programs rarely document every possible return code, so I’d rather explicity check for non-zero with the NEQ 0 style than assuming return codes will be 1 or greater on error. Parse errors should only be generated by the parser. 4 4 E_NOTICE Run-time notices.

It's not, if nothing goes wrong. Make sure you pass negative error numbers to SQLERRM. For example, you might want to roll back a transaction in the current block, then log the error in an enclosing block. Controlling PL/SQL Warning Messages To let the database issue warning messages during PL/SQL compilation, you set the initialization parameter PLSQL_WARNINGS.
The optional OTHERS handler catches all exceptions that the block does not name specifically. If the previous error handler was a class method, this function will return an indexed array with the class and the method name. But when the handler completes, the block is terminated. In that case, we change the value that needs to be unique and continue with the next loop iteration.
Redeclaring predefined exceptions is error prone because your local declaration overrides the global declaration. That is, the exception reproduces itself in successive enclosing blocks until a handler is found or there are no more blocks to search.
