Cursor Exception Handling In Oracle
run-time error such as stack overflow or division by zero stops normal processing and returns control to the operating system. With PL/SQL, a mechanism called exception handling oracle cursor exception handling within a loop 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 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 no data found exception in oracle 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 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, y

I'm wanting to raise an exception when data is found. I've been able to see the NO_DATA_FOUND exception. But not it's opposite. What would be the best way to do this, or is it not advised to perform this kind of operation. My Procedure is like the following PROCEDURE CHECK_ASSIGNED AS PLACEHOLDER INT; http://stackoverflow.com/questions/27971939/pl-sql-raise-exception-when-data-found BEGIN SELECT v.id INTO PLACEHOLDER FROM vinegar v WHERE NOT EXISTS ( SELECT 1 FROM home h WHERE h.sid = v.sid ) END; -- when data is found it means that and sid does not exist in the home table -- should raise exception and stop package exception plsql oracle11g package share|improve this question asked Jan 15 '15 at 19:57 Jonnny 2,39732755 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote accepted There is no built in error for "data found", because finding data is not considered an error by Oracle. However, it's not too difficult to treat this case as an error in specific cases. It depends somewhat on what you want to do with the exception. If you want to react to it in some way within the procedure, you can define your own exception, then raise it: PROCEDURE check_assigned AS exception err_data_found; placeholder INT; BEGIN SELECT v.id INTO placeholder FROM vinegar v WHERE NOT EXISTS (SELECT 1 FROM home h WHERE h.sid = v.sid); IF SQL%FOUND THEN RAISE err_data_found; END IF; EXCEPTION WHEN err_data_found THEN NULL; --do something END; On the other hand, if you just want to return the error

For example: DECLARE ex_custom EXCEPTION; BEGIN RAISE ex_custom; EXCEPTION WHEN ex_custom THEN DBMS_OUTPUT.PUT_LINE(SQLERRM); END; / The output is "User-Defined Exception". Is it possible to change that message? EDIT: Here no data found is some more detail. I hope this one illustrates what I'm trying to do better. DECLARE l_table_status VARCHAR2(8); l_index_status VARCHAR2(8); l_table_name VARCHAR2(30) := 'TEST'; l_index_name VARCHAR2(30) := 'IDX_TEST'; ex_no_metadata EXCEPTION; BEGIN BEGIN SELECT STATUS INTO l_table_status FROM USER_TABLES WHERE TABLE_NAME = l_table_name; EXCEPTION WHEN NO_DATA_FOUND THEN -- raise exception here with message saying -- "Table metadata does not exist." RAISE ex_no_metadata; END; BEGIN SELECT STATUS INTO l_index_status FROM USER_INDEXES WHERE INDEX_NAME = l_index_name; EXCEPTION WHEN NO_DATA_FOUND THEN -- raise exception here with message saying -- "Index metadata does not exist." RAISE ex_no_metadata; END; EXCEPTION WHEN ex_no_metadata THEN DBMS_OUTPUT.PUT_LINE('Exception will be handled by handle_no_metadata_exception(SQLERRM) procedure here.'); DBMS_OUTPUT.PUT_LINE(SQLERRM); END; / In reality, there are dozens of those sub-blocks. I'm wondering if there's a way to have a single user-defined exception for each of those sub-blocks to raise, but have it give a different message, instead of creating a separate user-defined exception for each sub-block. In .NET, it would be sort of like having a custom exception like this: public class ColorException : Exception { public ColorException(string message) : base(message) { } } And then, a metho
