CREATE DOMAIN

Available in: DSQL, ESQL

Context variables as defaults

Changed in: IB

Description

Any context variable that is assignment-compatible to the new domain's datatype can be used as a default. This was already the case in InterBase 6, but the Language Reference only mentioned USER.

Example

 create domain DDate as
    date
    default current_date
    not null
