26 sqlt - convert SQL schema using SQL::Translator
34 For a list of all parsers and producers:
38 To translate a schema:
40 sqlt -f|--from|--parser MySQL
41 -t|--to|--producer Oracle
47 -d|--debug Print debug info
48 -v|--validate Validate the schema
49 --version Show the version of SQL::Translator
50 --trace Print parser trace info
51 --show-warnings Print warnings to STDERR
55 --dsn DSN for connecting to database
56 --db-user Database user
57 --db-password Database password
61 --fs The field separator
62 --rs The record separator
63 --no-trim Don't trim whitespace on fields
64 --no-scan Don't scan fields for data types and sizes
68 --add-drop-table Add 'DROP TABLE' statements before creates
69 --no-comments Don't include comments in SQL output
71 Diagram Producer Options:
73 --imap-file Filename to put image map data
74 --imap-url URL to use for image map
76 Dumper Producer Options:
78 --skip Comma-separated list of tables to skip
79 --skiplike Regex for tables to skip
80 --dumper-db-user Database user for dumper script
81 --dumper-db-pass Database password for dumper script
82 --dumper-dsn DSN for dumper script
83 --add-truncate Add "TRUNCATE TABLE" statements for each table
85 HTML/POD Producer Options:
87 --pretty Use CGI::Pretty for the output
88 --title Title of schema
90 TTSchema Producer Options:
92 --template The path to the template
93 --tt-var var=value Pass extra variables to the template
95 XML-SQLFairy Producer Options:
97 --add-prefix Use an explicit namespace prefix of 'sqlf:'
98 --prefix=<p> Use the namespace prefix given as argument.
99 --no-newlines Write the XML as a single line.
100 --indent=<n> Use <n> characters of whitespace to indent the XML.
104 This script is part of the SQL Fairy project. It will try to convert
105 any source file for which it has a grammar into any format for which
108 If using "show-warnings," be sure to redirect STDERR to a separate file.
109 In bash, you could do this:
111 $ sql_translator.pl -f MySQL -t PostgreSQL --show-warnings \
114 You can specify a parser or producer located in any module that Perl
115 knows about, allowing you to easily substitute your own.
