cocl04 has asked for the wisdom of the Perl Monks concerning the following question:

All, I am trying to load data from a '*.csv' file to Oracle via the Oracle::SQLLoader module in a Windows enviorment. The code will not execute Below is the code. When I run it, I get the following error: Use of uninitialized value in concatenation (.) or string at C:/Perl/site/lib/Oracle/SQLLoader.pm line 576.

Does anyone out there have any suggestions?

Code: 

#!/usr/local/bin/perl

use strict;
use warnings;
use diagnostics;
use Oracle::SQLLoader qw/$CHAR $INT $DECIMAL $DATE/;

### load a simple comma-delimited file to a single table
my $ldr = new Oracle::SQLLoader(
                 infile => 'C:\Sales Report Thru 12 March 2009.csv',
                 terminated_by => ',',
                 username => 'xxxxx',
                 password => 'xxxxx',
                sid => 'xxxxx'
                    );
$ldr->addTable(table_name => 'testTableName');

$ldr->addColumn(column_name => 'Location_ID');
$ldr->addColumn(column_name => 'Type_Description');
$ldr->addColumn(column_name => 'Type_ID');
$ldr->addColumn(column_name => 'DetailType');
$ldr->addColumn(column_name => 'Amount');

$ldr->executeLoader() || warn "Problem executing sqlldr: \n";

    That line in the source code references the environment variable "Oracle_Home" - perhaps that has not been set.
    From the Oracle-SQLLoader README: 
    You should have the following environment variables set:
  ORACLE_HOME   - the location of the Oracle installation
  ORACLE_SID    - the database instance name
  ORACLE_USERID - the username and password to connect to the database
+ as the format is username/password (e.g. scott/tiger)

      Thank you so much for your input! That worked. I was missing the environment variables. Below is the code that worked. 

      #!/usr/local/bin/perl

use strict;
use warnings;
use diagnostics;
use Oracle::SQLLoader qw/$CHAR $INT $DECIMAL $DATE/;

# Oracle Path
$ENV{'ORACLE_HOME'} = "C:/oracle/ora92"; 
$ENV{'ORACLE_USER'} = "xxxx"; 
$ENV{'ORACLE_PASS'} = "xxxx";
$ENV{'ORACLE_SID'} = "xxxxx";

my $user = $ENV{'ORACLE_USER'};
my $pass = $ENV{'ORACLE_PASS'};
my $sid = $ENV{'ORACLE_SID'}; 

### load a simple comma-delimited file to a single table
my $ldr = new Oracle::SQLLoader(
                 infile => 'C:\Sales_Report_Thru_12_March_2009.csv',
                 terminated_by => ',',
                 username => $user,
                 password => $pass,
                sid => $sid
                    );
                   
$ldr->addTable(table_name => 'fs_bbbs_collections',
               when_clauses => "WHEN (01) <> 'Location_ID'
                                and (01) <> 'Type_Description'
                                and (01) <> 'Type_ID'
                                and (01) <> 'DetailType'
                                and (01) <> 'ItemCount'
                                and (01) <> 'Amount'");
 
$ldr->addColumn(column_name => 'Location_ID');
$ldr->addColumn(column_name => 'Type_Description');
$ldr->addColumn(column_name => 'Type_ID');
$ldr->addColumn(column_name => 'DetailType');
$ldr->addColumn(column_name => 'ItemCount');
$ldr->addColumn(column_name => 'Amount');

$ldr->executeLoader();

my $rejects = $ldr->getNumberRejected();

my $runtimeSecs = $ldr->getElapsedSeconds();
my $secsOnCpu = $ldr->getCpuSeconds();

    I wonder if there are some 'blank' rows in the csv file? Also, do you see all the data loaded into Oracle?
