Oracle Sql Error Message Text

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 oracle sqlerrm certain kinds of errors meaningful to your PL/SQL program. With many programming languages,
Oracle Raise Exception With Message
unless you disable error checking, a run-time error such as stack overflow or division by zero stops normal processing functions for error trapping are contained in which section of a pl/sql block and returns control to the operating system. 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 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 pl sql exception handling examples 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, 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 XY

Differences in TimesTen: exception handing and error behavior Understanding exceptions This section provides an overview of exceptions sqlerror in PL/SQL programming, covering the following topics: About exceptions Exception types About exceptions An exception is a PL/SQL error that is raised during program execution, either implicitly by https://docs.oracle.com/cd/A97630_01/appdev.920/a96624/07_errs.htm TimesTen or explicitly by your program. Handle an exception by trapping it with a handler or propagating it to the calling environment. For example, if your SELECT statement returns multiple rows, TimesTen returns an error (exception) at runtime. As the following example shows, you would see TimesTen error 8507, then the associated ORA error message. (ORA https://docs.oracle.com/cd/E11882_01/timesten.112/e21639/exceptions.htm messages, originally defined for Oracle Database, are similarly implemented by TimesTen.) Command> DECLARE > v_lname VARCHAR2 (15); > BEGIN > SELECT last_name INTO v_lname > FROM employees > WHERE first_name = 'John'; > DBMS_OUTPUT.PUT_LINE ('Last name is :' || v_lname); > END; > / 8507: ORA-01422: exact fetch returns more than requested number of rows 8507: ORA-06512: at line 4 The command failed. You can handle such exceptions in your PL/SQL block so that your program completes successfully. For example: Command> DECLARE > v_lname VARCHAR2 (15); > BEGIN > SELECT last_name INTO v_lname > FROM employees > WHERE first_name = 'John'; > DBMS_OUTPUT.PUT_LINE ('Last name is :' || v_lname); > EXCEPTION > WHEN TOO_MANY_ROWS THEN > DBMS_OUTPUT.PUT_LINE (' Your SELECT statement retrieved multiple > rows. Consider using a cursor.'); > END; > / Your SELECT statement retrieved multiple rows. Consider using a cursor. PL/SQL procedure successfully completed.

What is the WHEN OTHERS clause in Oracle? The WHEN OTHERS clause is used to trap all remaining exceptions that have not been handled by your Named System Exceptions and Named Programmer-Defined Exceptions. oracle sql error Syntax We will take a look at the syntax for the WHEN OTHERS clause in both procedures and functions. Syntax for Procedures The syntax for the WHEN OTHERS clause in a procedure is: CREATE [OR REPLACE] PROCEDURE procedure_name [ (parameter [,parameter]) ] IS [declaration_section] BEGIN executable_section EXCEPTION WHEN exception_name1 THEN [statements] WHEN exception_name2 THEN [statements] WHEN exception_name_n THEN [statements] WHEN OTHERS THEN [statements] END [procedure_name]; Syntax for Functions The syntax for the WHEN OTHERS clause in a function is: CREATE [OR REPLACE] FUNCTION function_name [ (parameter [,parameter]) ] RETURN return_datatype IS | AS [declaration_section] BEGIN executable_section EXCEPTION WHEN exception_name1 THEN [statements] WHEN exception_name2 THEN [statements] WHEN exception_name_n THEN [statements] WHEN OTHERS THEN [statements] END [function_name]; Example Here is an example of a procedure that uses a WHEN OTHERS clause: CREATE OR REPLACE PROCEDURE add_new_order (order_id_in IN NUMBER, sales_in IN NUMBER) IS no_sales EXCEPTION; BEGIN IF sales_in = 0 THEN RAISE no_sales; ELSE INSERT INTO orders (order_id, tot

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 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 method would have something like this: if (
