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.

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.
