Description INDICES OF collection_name A clause specifying that the values of the index variable correspond to the subscripts of the elements of the specified collection. With this

clause, you can use FORALL with nested tables where some elements have been deleted, or with associative arrays that have numeric subscripts. BETWEEN lower_bound AND upper_bound Limits the range of subscripts in the INDICES OF clause. If a subscript in the range does not exist in the collection, that subscript is skipped. VALUES OF index_collection_name dml_errors exception oracle A clause specifying that the subscripts for the FORALL index variable are taken from the values of the elements in another collection, specified by index_collection_name. This other collection acts as a set of pointers; FORALL can iterate through subscripts in arbitrary order, even using the same subscript more than once, depending on what elements you include in index_collection_name. The index collection must be a nested table, or an associative array indexed by PLS_INTEGER or BINARY_INTEGER, whose elements are also PLS_INTEGER or BINARY_INTEGER. If the index collection is empty, an exception is raised and the FORALL statement is not executed. index_name An undeclared identifier that can be referenced only within the FORALL statement and only as a collection subscript. The implicit declaration of index_name overrides any other declaration outside the loop. You cannot refer to another variable with the same name inside the statement. Inside a FORALL statement, index_name cannot appear in expressions and cannot be assigned a value. lower_bound .. upper_bound Numeric

ora-24381 Handling Exceptions in Bulk Operations Oracle Tips by Burleson Consulting The following Tip is from the outstanding bulk collect in oracle interview questions book "Oracle PL/SQL Tuning: Expert Secrets for High Performance Programming" by Dr. Tim Hall, Oracle ACE of the year, 2006: There are a number of issues regarding exception handling that https://docs.oracle.com/cd/B19306_01/appdev.102/b14261/forall_statement.htm must be considered when using bulk operations. In this section, rollback behavior of bulk operations and the methods available to control this behavior is examined. In order to demonstrate this functionality, a simple test table containing a single mandatory column must first be created. This is performed using the exception_test.sql script listed below. exception_test.sql CREATE TABLE exception_test ( id NUMBER(10) NOT http://www.dba-oracle.com/plsql/t_plsql_exceptions.htm NULL ); After the table is created, the way unhandled exceptions are treated during bulk operations can be examined. Unhandled Exceptions Unhandled exceptions during the execution of a bulk operation cause the entire operation to be rolled back. This functionality is demonstrated using the unhandled_exception.sql script listed below. unhandled_exception.sql DECLARE TYPE t_tab IS TABLE OF exception_test.id%TYPE; l_tab t_tab := t_tab(); BEGIN -- Fill the collection. FOR i IN 1 .. 100 LOOP l_tab.extend; l_tab(l_tab.last) := i; END LOOP; -- Cause a failure. l_tab(50) := NULL; EXECUTE IMMEDIATE 'TRUNCATE TABLE exception_test'; -- Perform a bulk operation. FORALL i IN l_tab.first .. l_tab.last INSERT INTO exception_test VALUES (l_tab(i)); END; / SET ECHO ON SELECT COUNT(*) FROM exception_test; SET ECHO OFF The unhandled_exception.sql script first creates and populates a collection. Next it assigns the value of NULL to the 50th element, thereby forcing an error. It then truncates the test table, attempts a bulk insert against it and displays the record count. The output from this script is listed below.

During the fourth one-day international, Mitchell returned the less than impressive figures of 0-72 off 10 overs. At the end of the fourth one-day international, England had finally notched a win against Australia. The logical conclusion to draw from all of this is that Mitchell Johnson is not a regular reader of this blog. On the plus side, I did get a couple of interesting comments from my last post about the performance differences between Log Errors and Save Exceptions. As well as Jim Dickson's input, Steve Feuerstein made some observations on the Toadworld site (which you can see here if you're interested). These comments both had a similar theme to the effect that, whilst Log Errors and Save Exceptions are similar, there are some differences beyond their relative performance. So, the aim of this post is to take a fresh look at these two mechanisms and how they compare. For the code examples, I'm going to step away from the horror show that has been England's cricket tour of Australia, and focus instead on the wacky world of Reality TV.

A 'plain vanilla' EXCEPTION handler may not report all errors that are thrown. Let's look at an example intentionally set up to fail inserts based on data from the EMP table. Table M is created with the EMP columns slightly re-ordered so the data types don't match up to the source: SQL> CREATE TABLE M 2 (EMPNO NUMBER(4) NOT NULL, 3 MGR NUMBER(4), 4 JOB VARCHAR2(9), 5 ENAME VARCHAR2(10), 6 HIREDATE DATE, 7 SAL NUMBER(7, 2), 8 COMM NUMBER(7, 2), 9 DEPTNO NUMBER(2)); Table created. SQL> The ENAME column is now fourth in the list, rather than second, If an attempt is made to simply 'shove' the EMP data into M it's certain to generate a number of 'invalid number' errors, but if the PL/SQL loop and exception handler aren't coded to take advantage of the BULK COLLECT error trapping at most one of the many errors generated will be reported: SQL> DECLARE 2 type emp_tbl is table of emp%rowtype; 3 emp_data emp_tbl; 4 cursor EMPINFO is 5 select * from emp; 6 7 8 BEGIN 9 OPEN EMPINFO; 10 LOOP 11 12 FETCH EMPINFO BULK COLLECT INTO emp_data LIMIT 200; 13 EXIT WHEN emp_data.count = 0; 14 BEGIN 15 DBMS_OUTPUT.PUT_LINE('Request rows ' || emp_data.COUNT); 16 FORALL i IN 1..emp_data.COUNT 17 INSERT INTO m VALUES emp_data(i); 18 19 EXCEPTION 20 WHEN others THEN -- Now we figure out what failed and why. 21 -- Output desired error message 22 dbms_output.put_line('-20999: Sumthin'' bad happened -- error stack follows'); 23 -- Output actual line number of error source 24 dbms_output.put(dbms_utility.format_error_backtrace); 25 -- Output the actual error number and message 26 dbms_output.put_line(dbms_utility.format_error_stack); 27 END; 28 29 END LOOP; 30 END; 31 / Request rows 18 -20999: Sumthin' bad happened -- error stack follows ORA-06512: at line 16 ORA-01722: invalid number PL/SQL procedure successfully completed.
