your PL/SQL program. With many programming languages, unless you disable error checking, a run-time error such as stack overflow oracle cursor exception handling within a loop or division by zero stops normal processing and returns control to the operating system. With PL/SQL, a mechanism called exception handling lets you "bulletproof" your program so that it can

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. 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

Description When you encounter an ORA-01001 error, the following error message will appear: pl sql exception ORA-01001: invalid cursor Cause You tried to reference a cursor that does not yet exist. This may have happened because: You've executed a FETCH cursor before OPENING the cursor. You've executed a CLOSE cursor before OPENING the cursor. You've executed a FETCH cursor after CLOSING the cursor. Resolution The option(s) to resolve this Oracle error are: Option #1 Make sure you haven't CLOSEd the cursor and are still referencing it in your code. Option #2 Make sure you've OPENed the cursor before calling a FETCH cursor or CLOSE cursor. Option #3 If everything else is fine, you may need to increase the AREASIZE and MAXOPENCURSORS options.
