|Subject: [PATCH] adding SYS_TIME just for fun.
|
|Hi,
|
|Whilst I was playing round with the European dates patch I noticed the sysfunc()
|that allows you to do :-
|
|create table test ( da date);
|insert into test values (SYS_DATE);
|
|and have the current system date inserted.
|
|So I thought it would be nice to have the SYS_TIME facility too.
|
|I've cloned the function and changed a few things and there you have it,
|you can now do:
|
|create table test2 ( ti time);
|insert into test2 values (SYS_TIME);
