[version] v2.3.7
[details]
configure a database (i use the wgcloud's default databse 'wgcloud')
then configure table as below

just wait for a moment and see log:

we can see database name is wgcloud.

in RDSConnection.java , the system use a blacklist as filter, but it's hard to filter all sql injection words.
