Oracle Error Table Log
insert into tb_dbms_errlog select *from dba_objects log errors into tb_log('tag_27042009_1') reject limit unlimited; 2228 rows created. We can also see that we haven't successfully inserted any records into the target table. The 101 insert statements issued in the loop will attempt to insert a value between 0 and 9 into dmlel.pkey ; as this field is the primary key, I would expect The "simple_expression" subclause allows you to specify a statement tag, which will be logged in the ORA_ERR_TAG$ field of the error logging table, to identify which statement caused the error. http://davegaubatz.com/oracle-error/oracle-error-codes-table.html
The tags we've used so far in this article would obviously be useless under such a scenario. Too large column values.3. the SQL%BULK_EXCEPTIONS collection only has two elements : error index - holds the index number of the record in the collection where the failure occurred error code - the Oracle error Restrictions The DML error logging functionality is not invoked when: Deferred constraints are violated.
Oracle Merge Log Errors Example
Secondly, although we didn't tell it to, the statement has automatically written the error to the $ERR table we just created. Does it matter where those 5 columns (most required error log information storing columns) need to be present on the error log table to be created? Direct-path INSERT or MERGE operations raise unique constraint or index violations.
By default, when a DML statement fails the whole statement is rolled back, regardless of how many rows were processed successfully before the error was detected. SQL> truncate table err$_target; Table truncated. However, in our case, where we're the cursor we're BULK COLLECTing is from another table, this isn't going to do us much good. Oracle Log Errors 11g This might be a string or any function whose result is converted to a string.
We've explored a few situations where the features of DML error logging come in handy, and I'm sure that by now, any developers reading this article are brimming with dozens more.

We know this is fewer than the number of records in our staging table, so we should check the error log table, as follows (using Tom Kyte's print_table procedure for convenience). Oracle Error Logs Location The logical conclusion to draw from all of this is that Mitchell Johnson is not a regular reader of this blog. restrictions Error logging supports all DML operations, including INSERT FIRST|ALL and MERGE. Oracle supplies a built-in pl/sql package, DBMS_ERRLOG, specifically for this purpose.

Line 3: the LOG ERRORS clause is how we invoke DML error logging. http://davegaubatz.com/oracle-error/oracle-error.html COLUMN ora_err_mesg$ FORMAT A69 SELECT ora_err_number$, ora_err_mesg$ FROM err$_dest WHERE ora_err_tag$ = 'DELETE'; ORA_ERR_NUMBER$ ORA_ERR_MESG$ --------------- --------------------------------------------------------------------- 2292 ORA-02292: integrity constraint (TEST.DEST_CHILD_DEST_FK) violated - child record found 2292 ORA-02292: integrity constraint Of course, if your cursor is referencing your target table, you can always simply retrieve the rowid as part of the query using the ROWID pseudo-column in the SELECT clause. DBMS_ERRLOG.CREATE_ERROR_LOG copies all the table columns into the error log (unless the table has columns in unsupported datatype; see "Errors handled by DML Error Logging" below). Dbms_errlog In Oracle 11g
Unfortunately, there doesn't appear to be an attribute or exception to indicate that errors were logged, so the only option is to examine the error log table itself. OK, I just saw that your article contains the answer to my question: "Except for: Violated deferred constraints". Else, roll back. http://davegaubatz.com/oracle-error/oracle-error-message-table.html 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
Since 1998 Oracle's DBMS has been my primary tool, but I'm fascinated by all data-related technologies and applications. Reject Limit Unlimited External Table Oracle However, to create an error logging table, you need SELECT access on the base table or view, the CREATE TABLE privilege, as well as tablespace quota for the target tablespace. Violation of a constraint on a LONG, LOB, or object type column Trigger execution errors Type conversion errors arising from type conversion between a column in a subquery and the corresponding
SQL> select x, ora_err_mesg$ from err$_target; X ORA_ERR_MESG$ ------- ------------------------------------------------------------ 1 ORA-01400: cannot insert NULL into ("TARGET"."ETL_PROGRAM") 1 ORA-01400: cannot insert NULL into ("TARGET"."ETL_PROGRAM") Well, that's what you get for
commit; Commit complete.Now it is possible to check errors generated by the insert command in our error log table. This is where the ORA_ERR_TAG$ field and the "simple expression" in the error logging clause come into their own.In the listing below, I've used DBMS_RANDOM to randomize the values used All-or-nothing; basic SQL statement atomicity. Oracle Merge Statement Exception Handling Any opinions, comments, solutions or other commentary expressed by blog authors are not endorsed or recommended by Toolbox for IT or any vendor.
In our first DML error logging example, we used an unlimited reject limit. So -- if you can deal with a misleading error message --- here's the hack. DBMS_OUTPUT.PUT_LINE('Error No is : '||l_idx); DBMS_OUTPUT.PUT_LINE('First Name is : '||tbl_orig_cast(l_idx).first_name); DBMS_OUTPUT.PUT_LINE('Last Name is : '||tbl_orig_cast(l_idx).last_name); DBMS_OUTPUT.PUT_LINE('Count of rowids = '||tbl_rowid.COUNT); DBMS_OUTPUT.PUT_LINE('Rowid = '||tbl_rowid(l_idx)); tbl_err(j).ora_err_number$ := SQL%BULK_EXCEPTIONS(j).error_code; tbl_err(j).ora_err_mesg$ := SQLERRM( SQL%BULK_EXCEPTIONS(j).error_code * http://davegaubatz.com/oracle-error/oracle-error-when.html overview of dml error logging With this feature, we can add a clause to our bulk DML statements (INSERT, UPDATE, MERGE and DELETE) to prevent the statement failing on hitting exceptions
