7 sql2xls.pl - convert sql queries on file system to Excel file
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
16 Comments in sql files (lines beginning with C<-->) will be placed
17 in first line in bold.
19 To specify database on which SQL query is executed
20 C<\c database> syntax is supported.
22 You can also run script from command line, and it will produce
23 C<sql_reports.xls> file.
25 If run within directory, it will use files in it to produce file.
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.
33 Only required file is this script C<< sql2xls.cgi >>
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
38 ScriptAlias /xls-reports /srv/SQL2XLS/sql2xls.cgi
40 in Apache's virtual host configuration to get nice URLs
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
46 $dsn = 'DBI:mysql:dbname=';
47 $database = 'database';
50 $path = 'sql_reports.xls';
52 $db_encoding = 'utf-8';
53 $xls_date_format = 'dd.mm.yyyy';
59 There is none. Use apache auth modules if you need it.
