10g » Here DML Error Logging in Oracle 10g Database Release 2 In some oracle 10g installation error situations the most obvious solution to a problem is a DML statement (INSERT ... SELECT, UPDATE, DELETE), but you may choose alert log in oracle 10g to avoid DML because of the way it reacts to exceptions. By default, when a DML statement fails the whole statement is rolled back, regardless of how many rows were processed successfully before the

error was detected. In the past, the only way around this problem was to process each row individually, preferably with a bulk operation using FORALL and the SAVE EXCEPTIONS clause. In Oracle 10g Database Release 2, the DML error logging feature has been introduced to solve this problem. Adding the appropriate LOG ERRORS clause on to most INSERT, UPDATE, MERGE and DELETE statements enables the operations to complete,

regardless of errors. This article presents an overview of the DML error logging functionality, with examples of each type of DML statement. Syntax Restrictions Sample Schema Insert Update Merge Delete Performance Syntax The syntax for the error logging clause is the same for INSERT, UPDATE, MERGE and DELETE statements. LOG ERRORS [INTO [schema.]table] [('simple_expression')] [REJECT LIMIT integer|UNLIMITED] The optional INTO clause allows you to specify the name of the error logging table. If you omit this clause, the the first 25 characters of the base table name are used along with the "ERR$_" prefix. The simple_expression is used to specify a tag that makes the errors easier to identify. This might be a string or any function whose result is converted to a string. The REJECT LIMIT is used to specify the maximum number of errors before the statement fails. The default value is 0 and the maximum values is the keyword UNLIMITED. For parallel DML operations, the reject limit is applied to each parallel server. Restrictions The DML error logging functionality is not invoked when: Deferred constraints are violated. Direct-path INSERT or MERGE operations raise unique constraint or index violations. UPDATE or MERGE operations raise a unique constraint or index violation. In add

Have you ever tried to update 30 million records, only to have the update fail after twenty minutes because one record in 30 million fails a check constraint? Or, how about an insert-as-select that fails on row 999 of 1000 because one column value is too large? With DML error logging, adding one clause to your insert statement would cause the 999 correct records to be inserted log in oracle successfully, and the one bad record to be written out to a table for you to resolve. This article will show you how to use DML error logging in your INSERT, UPDATE, MERGE and DELETE statements. Getting started Let's start by creating a table with a few constraints for us to violate: SQL> create table dmlel 2> (pkey varchar2(100) primary key, field1 varchar2(1), field2 varchar2(10) not null); Table created. Now, let's write a script that will fail without DML error logging. The following script will insert a few rows, and then fail with "value too large for column": declare i number; begin i := 0; while i <= 10 loop insert into dmlel (pkey, field1, field2) values (i, i, i); i := i+1; end loop; end; / * ERROR at line 1: ORA-12899: value too large for column "BULKLOAD"."DMLEL"."FIELD1" (actual: 2, maximum: 1) ORA-06512: at line 5 In order to handle this error with DML Error Logging, we first have to create a table for the DML errors to be logged to. Oracle refers to such a table, unsurprisingly, as an error logging table. Creating the Error Logging Table There are two ways to create the error logging table -- automatically or manually. We'll start with the automatic method. Oracle supplies a built-in pl/sql package, DBMS_ERRLOG, spe
