It will take hours to add fields 1 by 1 waiting for you to say what the next database error is.
I suggest you start doing them yourself, 1 by 1, it is not difficult.
Each time you get a new error you just replace the phrasegroup_XXXX from the error into the ALTER statement:
Code:
ALTER TABLE `language` ADD `phrasegroup_XXXXX` MEDIUMTEXT NULL DEFAULT NULL
I tried a few different things but to no avail, so your only option is above.
