Function Syntax Purpose
UTF-8 bytes and has no knowledge of
unicode characters (neither for the
whitespace string nor for length
computation).
replace string replace(string, string, string) replace every occurrence of arg2 in arg1
with arg3 and return the resulting string
Mathematical Functions
Function Syntax Purpose Example
sign int sign(double)
int sign(time)
int sign(date)
abs double abs(double)
round
.
rounddown
Date Functions
decfloat abs(decfloat)
decfloat abs(decfloat)
time abs(time)
Sign returns -1, 0 or 1
depending on the sign of its
argument. Sign is
implemented for all numeric
types, date and time.
Abs returns arg, if arg is
positive or zero, -arg else.
Abs is implemented for all
numeric types and time.
double round(double, int) round does rounding of
absolute values toward zer
while the sign is retained
double rounddown(double,
int)
rounddown rounds toward
negative infinity making
rounddown(-1.1, 0) = -2
Function Syntax Purpose
round(123.456, 0) = 123
round(123.456, 1) = 123.5
round(-123.456, 1) = -123.5
round(123.456, -1) = 120
rounddown(123.456, -1) =
120
rounddown(-123.456, -1) =
-130
utctolocal utctolocal(datearg, timezonearg) interprets datearg (a date, without
timezone) as utc and convert it to the
timezone named by timezonearg (a
string)
localtoutc localtoutc(datearg, timezonearg) converts the local datetime datearg to
the timezone specified by the string
timezonearg, return as a date
weekday weekday(date) returns the weekday as an integer in the
range 0..6, 0 is monday.
now now() returns the current date and time
