Webmin - how to access the db-tables

can acces the db-overwiew - where all the dbs are visible

here i have the following options
SQL select table
Invert Selection
Create a new database

what i want to achieve is to access a table overview on one db

but i cant

SQL select table_schema,table_name from information_schema.views where table_schema = ? failed:
Can't create/write to file '/var/tmp/mysql.5u7n3M/#sql_608_0.MYI' (Errcode: 2)

not really an OSM related question, is it ?

I did a search for your error and found https://sourceforge.net/p/webadmin/bugs/4155/
Does that help ?
