ALTER DOMAIN

Rename domain
SET DEFAULT to any context variable

Available in: DSQL, ESQL

Rename domain

Added in: IB

Description: Renaming of a domain is possible with the TO clause. This feature was introduced in InterBase 6, but left out of the Language Reference.

Example:

alter domain posint to plusint
The TO clause can be combined with other clauses and need not come first in that case.

SET DEFAULT to any context variable

Changed in: IB

Description: Any context variable that is assignment-compatible to the 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:

alter domain DDate
  set default current_date
