TOO_MANY_ROWS 01422 -1422 It is raised when s SELECT INTO statement returns more than one row. If you know that your database operations might raise specific internally defined exceptions that do not have names, then give them names so that you can write exception handlers specifically for After an exception handler runs, the current block stops executing and the enclosing block resumes with the next statement. However, an exception name can appear only once in the exception-handling part of a PL/SQL block or subprogram. this page
For example, the following GOTO statement is illegal: DECLARE pe_ratio NUMBER(3,1); BEGIN DELETE FROM stats WHERE symbol = 'XYZ'; SELECT price / NVL(earnings, 0) INTO pe_ratio FROM stocks WHERE symbol = Exceptions declared in a block are considered local to that block and global to all its sub-blocks. With many programming languages, unless you disable error checking, a run-time error such as stack overflow or division by zero stops normal processing and returns control to the operating system. Named system exceptions are exceptions that have been given names by PL/SQL. recommended you read
Next section will give you an example on raising user-defined exception, similar way you can raise Oracle standard exceptions as well. You need only include an exception-handling part in each block where errors might occur. Advantages of PL/SQL Exceptions Using exceptions for error handling has several advantages. In the latter case, PL/SQL returns an unhandled exception error to the host environment.
RAISE_APPLICATION_ERROR Procedure You can invoke the RAISE_APPLICATION_ERROR procedure (defined in the DBMS_STANDARD package) only from a stored subprogram or method. Therefore, the RAISE statement and the WHEN clause refer to different exceptions. If the parameter is FALSE (the default), the error replaces all previous errors. Oracle Sqlcode List Returns the sequence number under which the error is stored.
Unlike variables, exceptions cannot appear in assignment statements or SQL statements. Dup_val_on_index For example, ORA-06500 (PL/SQL: storage error) has the predefined name STORAGE_ERROR. LOGIN_DENIED Your program attempts to log on to Oracle with an invalid username and/or password. You can write handlers for predefined exceptions using the names in the following list: Exception Oracle Error SQLCODE Value ACCESS_INTO_NULL ORA-06530 -6530 CASE_NOT_FOUND ORA-06592 -6592 COLLECTION_IS_NULL ORA-06531 -6531 CURSOR_ALREADY_OPEN ORA-06511 -6511
But, if the need arises, you can use a locator variable to track statement execution, as follows: DECLARE stmt INTEGER := 1; -- designates 1st SELECT statement BEGIN SELECT ... Oracle No_data_found Words that are both anagrams and synonyms of each other Grayscale not working in simple TikZ What does the image on the back of the LotR discs represent? Thus HandleAll should have been called with p_Top = TRUE. */ PROCEDURE StoreStacks(p_Module IN errors.module%TYPE, p_SeqNum OUT errors.seq_number%TYPE, p_CommitFlag BOOLEAN DEFAULT FALSE); END ErrorPkg; / Error Handling Package Body CREATE OR So, only an OTHERS handler can catch the exception.
PL/SQL supports programmers to catch such conditions using EXCEPTION block in the program and an appropriate action is taken against the error condition. https://www.techonthenet.com/oracle/errors/ For each exception handler, carefully decide whether to have it commit the transaction, roll it back, or let it continue. Oracle Predefined Exceptions 11g It should be FALSE at other levels. */ PROCEDURE HandleAll(p_Top BOOLEAN); /* Prints the error and call stacks (using DBMS_OUTPUT) for the given module and sequence number. */ PROCEDURE PrintStacks(p_Module IN Oracle Pragma Exception_init A pragma is a compiler directive that is processed at compile time, not at run time.
Example 11-11 Reraising Exception DECLARE salary_too_high EXCEPTION; current_salary NUMBER := 20000; max_salary NUMBER := 10000; erroneous_salary NUMBER; BEGIN BEGIN IF current_salary > max_salary THEN RAISE salary_too_high; -- raise exception END IF; this website Normally, just the failed SQL statement is rolled back, not the whole transaction. All rights reserved. Table 11-1 Compile-Time Warning Categories Category Description Example SEVERE Condition might cause unexpected action or wrong results. Oracle Error Codes
If the transaction fails, control transfers to the exception-handling part of the sub-block, and after the exception handler runs, the loop repeats. LOGIN_DENIED ORA-01017 You tried to log into Oracle with an invalid username/password combination. That lets you refer to any internal exception by name and to write a specific handler for it. Get More Info This package stores general error information in the errors table, with detailed call stack and error stack information in the call_stacks and error_stacks tables, respectively.
You referenced an uninitialized row in a table. Types Of Exceptions In Oracle But remember, an exception is an error condition, not a data item. EXCEPTION WHEN NO_DATA_FOUND THEN INSERT INTO errors VALUES ('Error in statement ' || stmt); END; Copyright © 1996, 2002 Oracle Corporation.
In this link i found this list, are there anymore? The usual scoping rules for PL/SQL variables apply, so you can reference local and global variables in an exception handler. Exceptions also improve reliability.

asked 6 years ago viewed 40216 times active 2 years ago Linked 1 Where are Predefined ORACLE PL/SQL Exceptions? ACCESS_INTO_NULL Your program attempts to assign values to the attributes of an uninitialized (atomically null) object. With exception handlers, you need not know every possible error or everywhere that it might occur. http://back2cloud.com/error-code/pc-error-codes-list.php See Also: Example 12-13, where a bulk SQL operation continues despite exceptions Retrying Transactions After Handling Exceptions To retry a transaction after handling an exception that it raised, use this technique:
For a named exception, you can write a specific exception handler, instead of handling it with an OTHERS exception handler. After the exception handler runs, control transfers to the next statement of the outer block. COLLECTION_IS_NULL 06531 -6531 It is raised when a program attempts to apply collection methods other than EXISTS to an uninitialized nested table or varray, or the program attempts to assign values
