Shorthand casts

Available in: DSQL, ESQL, PSQL

Added in: IB

Description: When converting a string literal to a DATE, TIME or TIMESTAMP, Firebird allows the use of a shorthand “C-style” cast. This feature already existed in InterBase 6, but was never properly documented.

Syntax:

datatype 'date/timestring'

Examples:

update People set AgeCat = 'Old'
  where BirthDate < date '1-Jan-1943'

insert into Appointments
  (Employee_Id, Client_Id, App_date, App_time)
values
  (973, 8804, date 'today' + 2, time '16:00')

new.lastmod = timestamp 'now';
