The following topics are covered: Understanding exceptions Trapping exceptions Showing errors in ttIsql oracle predefined exceptions Differences in TimesTen: exception handing and error behavior Understanding exceptions This section provides oracle raise exception with message an overview of exceptions in PL/SQL programming, covering the following topics: About exceptions Exception types About exceptions An exception is exception handling in oracle 11g example a PL/SQL error that is raised during program execution, either implicitly by 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 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'; > types of exceptions in oracle 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. Exception types There are three types of exceptions: Predefined exceptions are error conditions that are defined by PL/SQL. Non-predefined exceptions include any standard TimesTen errors. User-defined exceptions are exceptions specific to your application. In TimesTen, these three types of exceptions are used in the same way as in Oracle Database. Exception Description How to handle Predefined TimesTen error One of approximately 20 errors that occur most often in PL/SQL code You are not required to declare these exceptions. They are predefined by TimesTen. TimesTen implic

PL/SQL Compile-Time Warnings Overview of PL/SQL Run-Time Error Handling In PL/SQL, an error condition is called an exception. An exception can be either internally defined (by the run-time system) or user-defined. https://docs.oracle.com/cd/E11882_01/timesten.112/e21639/exceptions.htm Examples of internally defined exceptions are ORA-22056 (value string is divided by zero) and ORA-27102 (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 your own exceptions in the declarative part of any PL/SQL block, subprogram, or package. For example, you might define an exception https://docs.oracle.com/cd/B28359_01/appdev.111/b28370/errors.htm named insufficient_funds to flag overdrawn bank accounts. 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 or invocations of the procedure DBMS_STANDARD.RAISE_APPLICATION_ERROR. 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. For information about managing errors when using BULK COLLECT, see Handling FORALL Exceptions (%BULK_EXCEPTIONS Attribute). Example 11-1 calculates a price-to-earnings ratio for a company. If the company has zero earnings, the division operation raises the predefined exception ZERO_DIVIDE, the execution of the block is interrupted, and control is transferred to the exception handlers. The optional OTHERS handler catches all exceptions that the block does not name specifically. Example 11-1 Run-Time Error Handling DECLARE stock_price NUMBER :=
changes using the SQLSTATE status variable, as well as the SQL Communications Area (SQLCA) and the WHENEVER directive. You also learn how to diagnose problems using the Oracle Communications Area (ORACA).

The main reason in oracle for error handling is that it allows your program to continue operating in the presence of errors. Errors arise from design faults, coding mistakes, hardware failures, invalid user input, and many other sources. You cannot anticipate all possible errors, but you can plan to handle certain kinds of errors that are meaningful to your program. For the Pro*C/C++ Precompiler, error handling means detecting and recovering from SQL statement execution errors. You can exception handling in also prepare to handle warnings such as "value truncated" and status changes such as "end of data." It is especially important to check for error and warning conditions after every SQL data manipulation statement, because an INSERT, UPDATE, or DELETE statement might fail before processing all eligible rows in a table. Error Handling Alternatives There are several alternatives that you can use to detect errors and status changes in the application. This chapter describes these alternatives, however, no specific recommendations are made about what method you should use. The method is, after all, dictated by the design of the application program or tool that you are building. Status Variables You can declare a separate status variable, SQLSTATE or SQLCODE, examine its value after each executable SQL statement, and take appropriate action. The action might be calling an error-reporting function, then exiting the program if the error is unrecoverable. Or, you might be able to adjust data or control variables and retry the action. See Also: "The SQLSTATE Status Variable" and "Declaring SQLCODE" for complete information about these status variables. The SQL Communications Area Another alternative that you can use is to include the SQL Communications Area structure (sqlca) in your program. This structure contains components that are filled in at runtime after the SQL statement is
