I like HeidiSQL software very much for its simplicity, however I miss the phpMyAdmin function for compress exported sql file directly into zip or gzip file.
In HeidiSQL I have to manually compress sql file in program like 7Zip after exporting from HeidiSQL.
Another bad thing is that I have to repeat the same process when importing zip files into HeidiSQL. In reverse order of course (unpack zip file and import row sql file).
It is not very convenient.
Is there any similar software like HeidiSQL (on the Windows platform) which can import/export zip/gzip files?
I would suggest you to extract/backup data in Heidi as a big file with
.SQLextension. That one is quite easy to access/read/edit in plain text editors and almost all GUI and command line database managers have implemented restore using those SQL dumps.
