**SQL*Loader Log File Reference**

When SQL*Loader begins execution, it creates a log file. The log file contains a detailed summary of the load.

Most of the log file entries will be records of successful SQL*Loader execution. However, errors can also cause log file entries. For example, errors found during parsing of the control file will appear in the log file.

This chapter describes the following log file entries:

Header Entries

Global Entries

Table Entries

Data File Entries

Table Load Entries

Summary Statistics

Header Information

The Header Section contains the following entries:

date of the run

software version number

For example:

SQL*Loader: Version 7.1.3.0.0 - Production on Mon Nov 26...

Copyright (c) Oracle Corporation...

Global Information

The Global Information Section contains the following entries:

names of all input/output files

echo of command-line arguments

continuation character specification

If the data is in the control file, then the data file is shown as "*".

For example:

Control File:   LOAD.CTL

Data File:      LOAD.DAT

  Bad File:       LOAD.BAD

  Discard File:   LOAD.DSC

 (Allow all discards)

Number to load: ALL

Number to skip: 0

Errors allowed: 50

Bind array:     64 rows, maximum of 65536 bytes

Continuation:   1:1 = '*', in current physical record

Path used:      Conventional

Table Information

The Table Information Section provides the following entries for each table loaded:

table name

load conditions, if any. That is, whether all record were loaded or only those meeting WHEN-clause criteria.

INSERT, APPEND, or REPLACE specification

the following column information:

if found in data file, the position, length, datatype, and delimiter

if specified, RECNUM, SEQUENCE, or CONSTANT

if specified, DEFAULTIF, or NULLIF

For example:

Table EMP, loaded from every logical record.

Insert option in effect for this table: REPLACE

   Column Name                Position   Len  Term Encl Datatype

--------------------------------------   ---  ---- ---- ---------

   EMPNO                           1:4     4            CHARACTER

   ENAME                          6:15    10            CHARACTER

   JOB                           17:25     9            CHARACTER

   MGR                           27:30     4            CHARACTER

   SAL                           32:39     8            CHARACTER

   COMM                          41:48     8            CHARACTER

   DEPTNO                        50:51     2            CHARACTER

Column EMPNO is NULL if EMPNO = BLANKS

Column MGR is NULL if MGR = BLANKS

Column SAL is NULL if SAL = BLANKS

Column COMM is NULL if COMM = BLANKS

Column DEPTNO is NULL if DEPTNO = BLANKS

Datafile Information

The Datafile Information Section appears only for datafiles with data errors, and provides the following entries:

SQL*Loader/Oracle data records errors

records discarded

For example:

        Record 2: Rejected - Error on table EMP.

        ORA-00001:  unique constraint <name> violated

        Record 8: Rejected - Error on table EMP, column DEPTNO.

        ORA-01722:  invalid number

        Record 3: Rejected - Error on table PROJ, column PROJNO.

        ORA-01722:  invalid number

Table Load Information

The Table Load Information Section provides the following entries for each table that was loaded:

number of rows loaded

number of rows that qualified for loading but were rejected due to data errors

number of rows that were discarded because they met no WHEN-clause tests

number of rows whose relevant fields were all null

For example:

The following indexes on table EMP were processed:

Index EMPIX was left in Direct Load State due to

ORA-01452: cannot CREATE UNIQUE INDEX; duplicate keys found

Table EMP:

        7 Rows successfully loaded.

        2 Rows not loaded due to data errors.

        0 Rows not loaded because all WHEN clauses were failed.

        0 Rows not loaded because all fields were null.

Summary Statistics

The Summary Statistics Section displays the following data:

amount of space used:

for bind array (what was actually used, based on what was specified by BINDSIZE)

for other overhead (always required, independent of BINDSIZE)

cumulative load statistics. That is, for all data files, the number of records that were:

skipped

read

rejected

discarded

beginning/ending time of run

total elapsed time

total CPU time (includes all file I/O but may not include background Oracle CPU time)

For example:

Space allocated for bind array:              65336 bytes (64 rows)

Space allocated for memory less bind array:  6470 bytes

Total logical records skipped:          0

Total logical records read:             7

Total logical records rejected:         0

Total logical records discarded:        0

Run began on Mon Nov 26 10:46:53 1990

Run ended on Mon Nov 26 10:47:17 1990

Elapsed time was:     00:00:15.62

CPU time was:         00:00:07.76
