137 sql_translator.pl - convert an SQL database schema
143 ./sql_translator.pl -h|--help
145 For a list of all parsers and producers:
147 ./sql_translator.pl -l|--list
149 To translate a schema:
152 -f|--from|--parser MySQL
153 -t|--to|--producer Oracle
159 -d|--debug Print debug info
160 -v|--validate Validate the schema
161 --trace Print parser trace info
162 --no-comments Don't include comments in SQL output
163 --show-warnings Print to STDERR warnings of conflicts, etc.
164 --add-drop-table Add 'drop table' statements before creates
168 --fs The field separator
169 --rs The record separator
170 --no-trim Don't trim whitespace on fields
171 --no-scan Don't scan fields for data types and sizes
175 --imap-file Filename to put image map data
176 --imap-url URL to use for image map
180 This script is part of the SQL Fairy project
181 (http://sqlfairy.sourceforge.net/). It will try to convert any
182 database syntax for which it has a grammar into some other format it
185 If using "show-warnings," be sure to redirect STDERR to a separate file.
186 In bash, you could do this:
188 $ sql_translator.pl -f MySQL -t PostgreSQL --show-warnings file.sql \
