ResultSetMetaData for Encrypt ResultSet

[tristaZero]

When users use encrypt data source to get encrypt resultset, we need to consider the resultset metadata. Especially, when users use ShardingQueryAssistedEncryptor, how about the assistedQueryColumn in resultset metadata?

assistedQueryColumn shoule be invisible for users.

hello @tristaZero , @terrymanu

I have a question about this issues.
When the following SQL statement is executed

select *  from mytable_with_assistedQueryColumn;
select assistedQueryColumn from mytable_with_assistedQueryColumn;

assistedQueryColumn can be returned normally;

In this case,why assistedQueryColumn need to be invisible to users?

@zhouchangjiang You're right, we need to overwrite interface of resultSetMetaData to hide assistedQueryColumn.
