FileSender supports several different database back-ends, by virtue of PHP's PDO.

Currently there are 3 back-ends that are known to work: PostgreSQL, MySQL, and SQLite.

Assumptions:

  • The target database has the right schema, tables, etc, and is empty. See the create scripts in the scripts/ directory.
  • Both the source and destination database are called filesender

Postgres to MySQL

Shell script that does:

  1. pg_dump
  2. Quote field names with backticks
  3. Remote any SET statements
  4. Remove any SELCT pg_catalog.setval statements

pg_dump -U username -h hostname -a --inserts -t 'files' -t 'logs' filesender |
sed -r 's/^(INSERT\ INTO\ )(files|logs)(\ VALUES\ )/\1`\2`\3/g' |
sed -r '/SET\ ([a-z_]*)\ =\ (.*);/d' |
sed -r '/SELECT\ pg_catalog.setval(.*);/d' |
mysql -u username -h hostname -p filesender

 

PostgreSQL to SQLite

pg_dump -U username -h hostname -a --inserts filesender |
sed -r '/^INSERT INTO (file|log)s/!d' |
sed -r '/SET\ ([a-z_]*)\ =\ (.*);/d' |
sed -r '/SELECT\ pg_catalog.setval(.*);/d' |
sqlite3 filesender.sqlite

 

 

SQLite to PostgreSQL

fixme

sqlite3 filesender.sqlite |
grep -E --color=never "^INSERT\ INTO\ \"(logs|files)\" VALUES" |
psql -U username -h hostname filesender

 

 

SQLite to MySQL

fixme

sqlite3 filesender.sqlite .dump |
sed -r 's/^(INSERT\ INTO\ )"(logs|files)"(\ VALUES)/\1`\2`\3/g' |
grep --color=never "^INSERT INTO \`" |
