For information on specifying character data types as literals, refer to Text Literals. You specify the database character set when you create your database. When you create a table with a CHAR column, you specify the column length as size optionally followed by a length qualifier. In the byte length semantics, size is the number of bytes to store in the column. In the character length semantics, size is the number of code points in the database character set to store in the column. A code point may have from 1 to 4 bytes depending on the database character set and the particular character encoded by the code point. Oracle recommends that you specify one of the length qualifiers to explicitly document the desired length semantics of the column. Oracle ensures that all values stored in a CHAR column have the length specified by size in the selected length semantics. If you insert a value that is shorter than the column length, then Oracle blank-pads the value to column length. If you try to insert a value that is too long for the column, then Oracle returns an error.

First off, there’s only one database involved. Databases can have multiple user schemas, and each connection is to a schema in a database. User schemas can create multiple feature datasets, which are not equivalent to databases your problem description is very confusing in this regard, since “owner”, “user”, and “database” seem to have different than the conventional definitions.
Each connection, in addition to all the tables that a given user can see, will see ALL the feature datasets in the geodatabase instance. This is because, unlike tables, feature datasets are artificial constructs in the SDE. There is no efficient way to determine the contents of a feature dataset before it is opened, so they are all listed unexploded , and upon open, if you do not have at least SELECT access to every table listed in the metadata, the object will show as empty.
