Option Meaning
hh
HH
Represents hour. Hour is based on 24-hour clock. Always use
leading zeros for hour where appropriate, for example ’01’ for 1
am. ’00’ is also valid value for hour of 12 am.
nn Represents minute. Always use leading zeros for minute where
appropriate, for example ’08’ for 8 minutes.
ss[.ssssss] Represents seconds and fraction of a second.
aa Represents the a.m. or p.m designation.
pp Represents the p.m designation only if needed. (This is
incompatible with Adaptive Server IQ releases prior to 12.0;
previously, pp was synonymous with aa.)
hh Adaptive Server IQ assumes zero for minutes and seconds. For
example, if the
DATETIME value you enter is ’03’, Adaptive
Server IQ converts it to ’03:00:00.0000’.
hh:nn or hh:mm Adaptive Server IQ assumes zero for seconds. For example, if the
time value you enter is ’03:25’, Adaptive Server IQ converts it to
’03:25:00.0000’.
