Subject:Timestamp or Datetime?
View as plain text  
I am trying to create an inventory database and want to keep track of the date
and time of the inventory.  Should I use timestamp or timedate?  I am trying
both, but I can't seem to get any variables in the timedate field, is that
because I have timestamp as a field above it?  Can you have both Timestamp and
timedate in a table?

I would also like to write out my time statement in a web form ticket.  Do you
know how I can get the curmonth(d),curdate(d),curtime(d) from table?
But I have all this other data I am selecting out of the table first.  can I
just add another select statement at the end? and then how would I display
this in a web page?

my $dbh = Mysql->connect("", "test");

my $command="";
$command = "select formnum,coll,dept,build,comp,os,";
$command .= "ident,classi,fas,hwa,ip,cont,bios,speed,ram,drive,";
$command .= "nic,vid,printer,firstn,lastn,phone,email,patch,room,";
$command .= "sr2,client32,virus,corel,";
$command .= "y2kapps,y2kpass,rate,tester,info,d from y2k ";
$command .= "where dept LIKE \"\%$dept\%\" ";
$command .= "AND build LIKE \"\%$build\%\" ";
$command .= "AND comp LIKE \"\%$comp\%\" AND os LIKE \"\%$os\%\" ";
$command .= "AND formnum LIKE \"\%$formnum\%\" ";
$command .= "AND fas LIKE \"\%$fas\%\" AND lastn LIKE \"\%$lastn\%\" ";
$command .= "AND rate LIKE \"\%$rate\%\" ";
$command .= "order by \"$order\"";

d is the last variable and is the timestamp, if I add another select statement
get the curday,curmonth,curdate,curtime from d how do I make it a variable to
display back to the user on a web page.?

can I add a select statement at $command .= "select curday(d) etc. before the
part of the code?
