Oracle Error Details
Conclusions PL/SQL provides a wide range of features to help you catch and diagnose errors as well as communicate application-specific errors to your users. Take the Challenge! For example, when your program selects a column value into a character variable, if the value is longer than the declared length of the variable, PL/SQL aborts the assignment and raises Possibility of runtime errors after clean compile (use of Oracle Database SQL parser) The TimesTen PL/SQL implementation uses the Oracle Database SQL parser in compiling PL/SQL programs. (This is discussed in http://davegaubatz.com/oracle-error/oracle-error-when.html
To get more information, run ttIsql and use the command show errors. Example 10-13 Retrying a Transaction After an Exception CREATE TABLE results ( res_name VARCHAR(20), res_answer VARCHAR2(3) ); CREATE UNIQUE INDEX res_name_ix ON results (res_name); INSERT INTO results VALUES ('SMYTHE', 'YES'); INSERT This chapter contains these topics: Overview of PL/SQL Runtime Error Handling Advantages of PL/SQL Exceptions Summary of Predefined PL/SQL Exceptions Defining Your Own PL/SQL Exceptions How PL/SQL Exceptions Are Raised How TimesTen reports errors to your application so you can avoid returning unhandled exceptions. why not find out more

Showing errors in ttIsql You can use the show errors command in ttIsql to see details about errors you encounter in executing anonymous blocks or compiling packages, procedures, or functions. Carefully consider whether each exception handler should commit the transaction, roll it back, or let it continue. You might also use this package when compiling a complex application, made up of several nested SQL*Plus scripts, where different warning settings apply to different subprograms. VALUE_ERROR 06502 -6502 An arithmetic, conversion, truncation, or size-constraint error occurs.
A user-defined exception is one you have declared in the declaration section of a program unit. This handler is never called. You can also perform a sequence of DML operations where some might fail, and process the exceptions only after the entire operation is complete, as described in "Handling FORALL Exceptions with Oracle Error Codes And Solution Pdf An application can call raise_application_error only from an executing stored subprogram (or method).
A PL/SQL block cannot catch an exception raised by a remote subprogram. Oracle Raise Exception With Message Next, you need to decide how you want your program to deal with, or handle, that exception. Example 10-6 Using RAISE to Force a User-Defined Exception DECLARE out_of_stock EXCEPTION; number_on_hand NUMBER := 0; BEGIN IF number_on_hand < 1 THEN RAISE out_of_stock; -- raise an exception that we defined https://docs.oracle.com/cd/B28359_01/nav/lookup.htm?id=ERRMG A GOTO statement cannot branch into an exception handler, or from an exception handler into the current block.
Subsequent calls to SQLCODE and SQLERRM will return these values. Oracle Sqlerrm Advantages of PL/SQL Exceptions Using exceptions for error handling has several advantages. Figure 10-1 Propagation Rules: Example 1 Description of the illustration lnpls009.gif Figure 10-2 Propagation Rules: Example 2 Description of the illustration lnpls010.gif Figure 10-3 Propagation Rules: Example 3 Description of the That would give you more data but would, obviously, be much more complex.
- RAISE_APPLICATION_ERROR is part of package DBMS_STANDARD, and as with package STANDARD, you do not need to qualify references to it.
- Why would you want to do this?
- The system returned: (22) Invalid argument The remote host or network may be down.
- When this procedure is run, execution of the current PL/SQL block halts immediately and an exception (whose error code and message are set from the values passed to RAISE_APPLICATION_ERROR) is raised.
- To see any warnings generated during compilation, you use the SQL*Plus SHOW ERRORS command or query the USER_ERRORS data dictionary view.
- You code the pragma EXCEPTION_INIT in the declarative part of a PL/SQL block, subprogram, or package using the syntax PRAGMA EXCEPTION_INIT(exception_name, -Oracle_error_number); where exception_name is the name of a previously declared
- It could represent a mistake, or it could be intentionally hidden by a debug flag, so you might or might not want a warning message for it.

Oracle Raise Exception With Message
The built-in parameter SELF points to the object, and is always the first parameter passed to a MEMBER method. https://docs.oracle.com/cd/E28280_01/admin.1111/e15867/app_error_codes.htm Trapping user-defined exceptions You can define your own exceptions in PL/SQL in TimesTen, and you can raise user-defined exceptions explicitly with either the PL/SQL RAISE statement or the RAISE_APPLICATION_ERROR procedure. Oracle 11g Error Codes Sometimes the error is not immediately obvious, and could not be detected until later when you perform calculations using bad data. Oracle Error Codes List With Description Also, it can use the pragma EXCEPTION_INIT to map specific error numbers returned by raise_application_error to exceptions of its own, as the following Pro*C example shows: EXEC SQL EXECUTE /* Execute

Oracle Error Handling
When the sub-block ends, the enclosing block continues to execute at the point where the sub-block ends, as shown in Example 10-12. Every exception has an error code and an error message associated with it. Note See also the SQLCODE function. http://davegaubatz.com/oracle-error/oracle-error.html statementN; EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.put_line (SQLCODE); END; When I execute the block, Oracle Database will try to assign the value 100 to l_number.
Place the statement in its own sub-block with its own exception handlers. Oracle Database Errors And Solutions Example 10-16 Using the DBMS_WARNING Package to Display Warnings -- When warnings disabled, the following procedure compiles with no warnings CREATE OR REPLACE PROCEDURE unreachable_code AS x CONSTANT BOOLEAN := TRUE; CREATE OR REPLACE PROCEDURE plch_proc (divisor_in in NUMBER) IS BEGIN INSERT INTO plch_tab VALUES (100/divisor_in); EXCEPTION WHEN DUP_VAL_ON_INDEX AND NO_DATA_FOUND THEN RAISE; Steven Feuerstein's biography and links to more

With this logging procedure defined in my schema, I can now very easily and quickly write an exception handler as follows: EXCEPTION WHEN OTHERS THEN record_error(); RAISE; It takes me The process of raising exceptions and the structure of the exception section are described more fully later in this article. They might point out something in the subprogram that produces an undefined result or might create a performance problem. Oracle Error Codes Table Possible reasons include the following: An error occurs while computing the operation.

Scripting on this page enhances content navigation, but does not change the content in any way. 64/73 A Error Codes This chapter describes the Oracle Service Bus errors that can occur his comment is here In this example, show errors provides the following: Command> show errors; Errors for PACKAGE BODY EMP_ACTIONS: LINE/COL ERROR -------- ----------------------------------------------------------------- 13/13 PLS-00323: subprogram or cursor 'REMOVE_EMPLOYEE' is declared in a package
DUP_VAL_ON_INDEX 00001 -1 A program attempts to store duplicate values in a column that is constrained by a unique index. This kind of error message might be sufficient for reporting database errors, but what if an application-specific error—such as “Employee is too young” or “Salary cannot be greater than $1,000”—has been Because a block can reference only local or global exceptions, enclosing blocks cannot reference exceptions declared in a sub-block. You can use the RAISE statement to raise a user-defined exception or an Oracle Database predefined exception.
How your code responds to and deals with that error often spells the difference between a successful application and one that creates all sorts of problems for users as well as You can make the checking as general or as precise as you like. Because not every error in an application is due to a failure of internal processing in the Oracle Database instance. Refer to "SQLERRM Function" and "SQLCODE Function" in Oracle Database PL/SQL Language Reference for general information.
Exception Overview There are three categories of exceptions in the world of PL/SQL: internally defined, predefined, and user-defined. hostdef extension doesn't exist PL/SQL procedure successfully completed. Defining Your Own PL/SQL Exceptions PL/SQL lets you define exceptions of your own. For example: EXCEPTION WHEN INVALID_NUMBER THEN INSERT INTO ... -- might raise DUP_VAL_ON_INDEX WHEN DUP_VAL_ON_INDEX THEN ... -- cannot catch the exception END; Branching to or from an Exception Handler A
