Can't find the special schema.

[Tommy Lee]

I have two schema that are scA and scB.
I get getTablePrivileges("","scA","%")
but Can't get getTablePrivileges("","scB","%").
why I can't get scB TablePrivileges?
ps :
when I use getPrimaryKey("","scB","ALL_ACTIVITY"),
I can got the primaryKey.

You must have your first name, a space, then your last name, and obviously fictitious names are not allowed.

Tommy,
Do you have read access to the schema/table. If not, the commands should not work.
