SELECT, UPDATE, DELETE), but you may choose 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

dbms_errlog Tips Oracle oracle save exceptions tips by BurlesonJuly 23, 2015 When doing a batch insert you may receive data from a host of external locations. While it's nice to assume that https://oracle-base.com/articles/10g/dml-error-logging-10gr2 the data has been scrubbed and validated, there is always a chance that you will have invalid numeric and character data. The problem is how to deal with large volumes of errors and that is what the dbms_errlog package does for us.This dbms_errlog package allows DML operations to continue working properly despite errors http://www.dba-oracle.com/t_packages_dbms_errlog.htm that might occur during the procedure. To do this, dbms_errlog creates a table called an ?error log? table. Any records not processed by the DML operation due to errors will be inserted into this table allowing any problems in the operation to be analyzed and fixed later on.When doing massive DML operations, problems like these may arise: Data values that are too large for the column (e.g. inserting 40 characters into a varchar2(20). Partition mapping errors happen (No partition exists) Errors during triggers execution occur (mutating table error) Constraint violations (check, unique, referential and NOT NULL constraints) occur Type conversion errors (numeric with alpha characters, invalid dates) happen For these cases, the dbms_errlogpackage can be used to create a table that will store details about all DML operations that present errors.The following script demonstrates its use as seen in the package. DML errors of operation are simulated, then they are inserted in the log tabFunctions PSOUG Forum Oracle Blogs Search the Reference Library pages: FreeOracle MagazineSubscriptionsand Oracle http://psoug.org/reference/dbms_errlog.html White Papers Oracle DBMS_ERRLOG Version 11.1 General Information Source {ORACLE_HOME}/rdbms/admin/dbmserlg.sql First Available 10.2 Dependencies DBMS_ASSERT DBMS_SQL KUPD$DATA DBMS_OUTPUT DBMS_UTILITY PLITBLM Note: ...
