exception handing and error behavior Understanding exceptions This section provides an overview of exceptions oracle raise exception with message in PL/SQL programming, covering the following topics: About exceptions Exception types About exceptions An exception is a PL/SQL error that is oracle sqlerrm 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'; > 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 implicitly raises the error. Non-predefined TimesTen error Any other standard TimesTen error These must be declared in the decl
errors. The latter are called exceptions. Note: The types of exceptions in oracle language of warning and error messages depends on the

The USER_DUMP_DEST initialization parameter specifies https://docs.oracle.com/cd/E11882_01/appdev.112/e25519/errors.htm the current location of the trace files. You can find the value of this parameter by issuing SHOW PARAMETER USER_DUMP_DEST. For more information about trace files, see Oracle Database Performance Tuning Guide. Compile-Time Warnings While compiling stored PL/SQL units, the PL/SQL compiler generates warnings for conditions that are not serious enough to cause errors and prevent compilation—for example, using a deprecated PL/SQL feature. To see warnings (and errors) generated during compilation, either query the static data dictionary view *_ERRORS (described in Oracle Database Reference) or, in the SQL*Plus environment, use the command SHOW ERRORS. The message code of a PL/SQL warning has the form PLW-nnnnn. For the message codes of all PL/SQL warnings, see Oracle Database Error Messages. Table 11-1 summarizes the categories of warnings. Table 11-1 Compile-Time Warning Categories Category Description Example SEVERE Condition might cause unexpected action or wrong results.

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 exception handling in 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 (isRed) { throw new ColorException("Red is not allowed!"); } if (isBlack) { throw new ColorException("Black is not allowed!"); } if (isBlue) { throw new ColorExcep

RAISE_APPLICATION_ERROR tips Oracle Database Tips by Burleson Consulting March 3, 2015 Question: What does the PL/SQL raise_application_error code do? Answer: The raise_application_error is actually a procedure defined by Oracle that allows the developer to raise an exception and associate an error number and message with the procedure. This allows the application to raise application errors rather than just Oracle errors. Error numbers are defined between -20,000 and -20,999. Oracle provides the raise_application_error procedure to allow you to raise custom error numbers within your applications. You can generate errors and their associated text starting with -20000 and proceeding through -20999 (a grand total of 1,000 error numbers that you can use). Below we illustrate the use of the raise_application_error procedure. Using the raise_application_error procedure: DECLARE Balance integer := 24; BEGIN IF (nBalance <= 100) THEN Raise_Application_Error (-20343, 'The balance is too low.');END IF;END; In this example, error number -20343 is raised if the value of nBalance isn't greater than 100, yielding a message that looks like this: ORA-20343: The balance is too low. All other numbers belong to Oracle for its own errors. The message can be anything that will fit in a varchar2(2000). The final parameter passed to the procedure is a Bo
