sp_help

For tables that include an encrypted column, sp_help tablename displays whether a column is encrypted and whether the encrypted column has a decrypt default. For example:

create table encr_table(col1 int encrypt decrypt_default 1)

The output from this example is similar to:

Column_name   Type     Length   Prec   Scale   Nulls   Default_name
Rule_name    Access_Rule_name Computed_Column_object  Identity     Encrypted Decrypt_Default_name
-----------    ----    ------    ----   -----   -----   ------------ 
---------    --------------   --------------------    ---------  -------------------------
