ddlgen can generate decrypt_default statements (if set for an encrypted column) along with DDL of a table.
This example issues a ddlgen command on a table called employee which has an “ssn” column that is encrypted with encryption key “ssn_key,” and a decrypt default value that is set to “100”:
ddlgen -Usa -P -Sserver -TU -Nemployee
create table employee ( ssn int not null encrypt with ssn_key decrypt_default 100 , last_name int not null , first_name int not null ) lock allpages on 'default' go
