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 (see also --use-same-auth below)
57 --db-user Database user
58 --db-password Database password
62 --fs The field separator
63 --rs The record separator
64 --no-trim Don't trim whitespace on fields
65 --no-scan Don't scan fields for data types and sizes
69 --mysql-parser-version Target MySQL parser version for dealing with
70 /*! comments; default = 30000
72 MySQL Producer Options:
74 --mysql-version MySQL server version
76 General Producer Options
78 --producer-db-user Database user for producer
79 --producer-db-pass Database password for producer
80 --producer-dsn DSN for producer
81 --use-same-auth Use these DSN, user, password for producer output
85 --add-drop-table Add 'DROP TABLE' statements before creates
86 --quote-table-names Quote all table names in statements
87 --quote-field-names Qjuote all field names in statements
88 --no-comments Don't include comments in SQL output
90 PostgreSQL Producer Options:
92 --postgres-version PostgreSQL server version
94 Diagram Producer Options:
96 --imap-file Filename to put image map data
97 --imap-url URL to use for image map
99 Dumper Producer Options:
101 --skip Comma-separated list of tables to skip
102 --skiplike Regex for tables to skip
103 --add-truncate Add "TRUNCATE TABLE" statements for each table
105 HTML/POD Producer Options:
107 --pretty Use CGI::Pretty for the output
108 --title Title of schema
110 TTSchema Producer Options:
112 --template The path to the template
113 --tt-var var=value Pass extra variables to the template
114 --tt-conf option=value Pass extra config options to Template
116 XML-SQLFairy Producer Options:
118 --add-prefix Use an explicit namespace prefix of 'sqlf:'
119 --prefix=<p> Use the namespace prefix given as argument.
120 --no-newlines Write the XML as a single line.
121 --indent=<n> Use <n> characters of whitespace to indent the XML.
123 ClassDBI Producer Options:
125 --package Base package name for Class::DBI modules.
129 This script is part of the SQL Fairy project. It will try to convert
130 any source file for which it has a grammar into any format for which
133 If using "show-warnings," be sure to redirect STDERR to a separate file.
134 In bash, you could do this:
136 $ sql_translator.pl -f MySQL -t PostgreSQL --show-warnings \
139 You can specify a parser or producer located in any module that Perl
140 knows about, allowing you to easily substitute your own.
