121 sql_translator.pl - convert an SQL database schema
127 ./sql_translator.pl -h|--help
129 For a list of all parsers and producers:
131 ./sql_translator.pl -l|--list
133 To translate a schema:
136 -f|--from|--parser MySQL
137 -t|--to|--producer Oracle
143 -d|--debug Print debug info
144 --trace Print parser trace info
145 --no-comments Don't include comments in SQL output
146 --show-warnings Print to STDERR warnings of conflicts, etc.
147 --add-drop-table Add 'drop table' statements before creates
148 --xlate=foo/bar,baz/blech Overrides for field translation
152 This script is part of the SQL Fairy project
153 (http://sqlfairy.sourceforge.net/). It will try to convert any
154 database syntax for which it has a grammar into some other format it
157 If using "show-warnings," be sure to redirect STDERR to a separate file.
158 In bash, you could do this:
160 $ sql_translator.pl -f MySQL -t PostgreSQL --show-warnings file.sql \
