   in  EncryptMergedResult,for example:
       if  the column that  the findColumnProjection finds  is not a columnProject, such as  expressionProject ,findColumnProjection returns  Optional.empty() ;
      Can you provide a function to find  any column when the column findColumnProjection finds is  an expressionProject ,and the column expression include any encrypt column.
     For example:
       in table t_users include id,name,pwd column,the pwd is a encrypt column.
     when sql is select id ,name ,CONCAT(name,pwd) as val from t_user;
    getValue(val) find this column(val) is not a columnProject . and the express is "CONCAT(name,pwd)" include pwd is a encrypt. Can you provide a function to check this ?
