A database system providing encrypted column data support with decrypt default functionality. In a database system, a method providing automated encryption support for column data comprises steps of: defining Structured Query Language (SQL) extensions for creating and managing column encryption keys and database tables with encrypted column data; receiving an SQL statement specifying creation of a column encryption key; receiving an SQL statement specifying creation of a database table having particular column data encrypted with the column encryption key; receiving an SQL statement specifying a default value to be provided in response to requests for the column data without decrypt permission; in response to a subsequent database operation requesting encrypted column data from a user with decrypt permission, automatically decrypting the column data; and in response to a subsequent database operation requesting the encrypted column data from a user without decrypt permission, returning the default value.
