There are two tables

TableA
filedata_id | user_id | filename
1           | 1       | file.txt
2           | 1       | file2.txt


TableB   
a_id        | date    | filedataid | counter | state | cat_id | subcat_id | med_id
99          | 1242144 | 1          | 2       | v     | 55     |  56       | 90
100         | 1231232 | 2          | 3       | i     | 44     |  55       | 110

I want to move columns cat_id, subcat_id, med_id to TableA where tableA.filedata_id = TableB.filedataid

The result should be:

TableA
filedata_id | user_id | filename  | cat_id | subcat_id | med_id
1           | 1       | file.txt  | 55     | 56        | 90
2           | 1       | file2.txt | 44     | 55        | 110

and so on.

Is there a way to do this easily?
