Function Syntax Purpose
daysbetween daysbetween(date1, date2)
daysbetween(daydate1, daydate2)
daysbetween(seconddate1,
seconddate2)
daysbetween(longdate1, longdate2)
secondsbetween secondsbetween(seconddate1,
seconddate2)
secondsbetween(longdate1, longdate2)
returns the number of days (integer)
between date1 and date2. The first
version is an alternative to date2 - date1.
Instead of rounding or checking for
exactly 24 hours distance, this will
truncate both date values today
precision and subtract the resulting day
numbers, meaning that if arg2 is not the
calendar day following arg1,
daysbetween will return 1 regardless of
the time components of arg1 and arg2.
returns the number of seconds the first
to the second arg, as a fixed point
number. The returned value is positive if
the first argument is less than the
second. The return values are fixed18.0
in both cases (note that it may prove
more useful to use fixed11.7 in case of
longdate arguments).
component component(date, int) the int argument may be int the range
1..6, the values mean year, day, month,
hour, minute, second, respectively. If a
component is not set in the date, the
component function will return a default
value, 1 for the month or the day, 0 for
other components. The component
function may also be applied to
longdate and time types.
addseconds addseconds(date, int)
addseconds(seconddate, decfloat)
addseconds(longdate, decfloat)
adddays adddays(date, int)
Misc Functions
adddays(daydate, int)
adddays(seconddate, int)
adddays(longdate, int)
Return a date plus a number of seconds.
Fractional seconds will also be used in
case of longdate. Null handling is (in
opposition to the default done with
adds) to return null if any argument is
null.
Return a date plus a number of days.
Null handling is (in opposition to the
default done with adds) to return null if
any argument is null.
Function Syntax Purpose Example
if if(intarg, arg2, arg3) return arg2 if intarg is
considered true (not equal to
zero), else return arg3.
