Passing DateTime object to template query (i realy need help, this is my last chance)

[Cableguy]

I asked this question on mysql, cprogramming and codeguru forums and had 
no answers. So i guess this is my last chance... if you can't help me 
then nobody can (since you are developing mysql++).

DateTime lastLogon=row.lookup_by_name("LogonTime");
query<<"SELECT * FROM Posts WHERE CreationTime>%0q";
query.parse();

Template query is set, so when i execute it it works just fine (in this 
case):
result=query.store(SQLString("2005-03-03 12:00:00"));

But that's not what i want, I don't want to pass date & time as a 
string, I wanna pass it as DateTime object lastLogon but don't know how 
to convert it...

result=query.store(SQLString(lastLogon)); //this doesn't work



I'm realy new to this and i've searched mysql++ documentation but just 
couldn't find the answer :(
