7    sql2xls.pl - convert sql queries on file system to Excel file
8    
9    =head1 USAGE
10    
11    Each file in current directory which ends in C<*.sql> will
12    be converted to Excel sheet. If you want to have specific order, you can
13    prefix filenames with numbers which will be striped when creating sheet
14    names.
15    
16    Comments in sql files (lines beginning with C<-->) will be placed
17    in first line in bold.
18    
19    To specify database on which SQL query is executed
20    C<\c database> syntax is supported.
21    
22    You can also run script from command line, and it will produce
23    C<sql_reports.xls> file.
24    
25    If run within directory, it will use files in it to produce file.
26    
27    When called as CGI, directory name can be appended to name of script
28    to produce report for any sub-directory within directory where
29    C<sql2xls.cgi> is installed.
30    
31    =head1 INSTALLATION
32    
33    Only required file is this script C<< sql2xls.cgi >>
34    
35    If your server is configured to execute C<.cgi> files, you can
36    drop this script anywhere, but you can also add something like
37    
38       ScriptAlias /xls-reports /srv/SQL2XLS/sql2xls.cgi
39    
40    in Apache's virtual host configuration to get nice URLs
41    
42    To configure default database, user, password and other settings create
43    C<config.pl> file in same directory in which C<sql2xls.cgi> is with something
44    like this:
45    
46      $dsn      = 'DBI:mysql:dbname=';
47      $database = 'database';
48      $user     = 'user';
49      $passwd   = 'password';
50      $path     = 'sql_reports.xls';
51    
52      $db_encoding     = 'utf-8';
53      $xls_date_format = 'dd.mm.yyyy';
54    
55      $debug = 1;
56    
57    =head1 SECURITY
58    
59    There is none. Use apache auth modules if you need it.
