#Toad for oracle error codes codeWhen we built the sample schema we noted that the CODE column is optional in the SOURCE table, but mandatory in th DEST table. The structure of the log table includes maximum length and datatype independent versions of all available columns from the base table, as seen below. The owner, name and tablespace of the log table can be specified, but by default it is created in the current schema, in the default tablespace with a name that matches the first 25 characters of the base table with the " ERR$_" prefix. Custom name.ĭbms_errlog.create_error_log (dml_table_name => 'dest', Default name.ĭbms_errlog.create_error_log (dml_table_name => 'dest') Procedure in the DBMS_ERRLOG package, as shown below. This can be done manually or with the CREATE_ERROR_LOG A log table must be created for every base table that requires the DML error logging functionality. Once the basic tables are in place we can create a table to hold the DML error logs for the DEST. Notice that the CODE column is optional in the SOURCE table and mandatory in the DEST table. Create a dependant of the destination table.Ĭonstraint dest_child_dest_fk foreign key (dest_id) references dest(id) This following code creates and populates the tables necessary to run the example code in this article. In addition, the tracking of errors in LONG, LOB and object types is not supported, although a table containing these columns can be the target of error logging. #Toad for oracle error codes updateUPDATE or MERGE operations raise a unique constraint or index violation.Direct-path INSERT or MERGE operations raise unique constraint or index violations.The DML error logging functionality is not invoked when: For parallel DML operations, the reject limit is applied to each parallel server. The default value is 0Īnd the maximum values is the keyword UNLIMITED. The REJECT LIMIT is used to specify the maximum number of errors before the statement fails. This might be a string orĪny function whose result is converted to a string. The simple_expression is used to specify a tag that makes the errors easier to identify. The first 25 characters of the base table name are used along with the "ERR$_" prefix. The optional INTO clause allows you to specify the name of the error logging table. The syntax for the error logging clause is the same for INSERT, UPDATE, MERGE and DELETE statements. This article presents an overview of the DML error logging functionality, with examples of each type of DML statement. Adding the appropriate LOG ERRORS clause on to most INSERT, UPDATE, MERGE and DELETE statements enables the operations to complete, regardless of errors. In Oracle 10g Database Release 2, the DML error logging feature has been introduced to solve this problem. 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. 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. SELECT, UPDATE, DELETE), but you may choose to avoid multi-row DML because of the way it reacts to exceptions. In some situations the most obvious solution to a problem is a multi-row DML statement ( INSERT. Home » Articles » 10g » Here DML Error Logging in Oracle 10g Database Release 2
