Query Help - Just a question about writing a query...

[Rose]

I'm praciticing some queries and I have a couple questions. First, let me explain my practice queries -

I figured I'd just write a bunch of "INSERT INTO"'s for different calendar events (general holiday stuff).

[sql]
INSERT INTO calendar_events (eventid, userid, event, eventdate, public, subject, allowsmilies) VALUES (4, 1, 'Thanksgiving - US.\r\n\r\n\r\n', '2003-11-27', 1, 'Thanksgiving', 1);
[/sql]


My question is this - Must I set the eventid, or is there a way to have it automatically set itself. Reason being - I have events already added to the calendar and I just wondered if I needed to consecutively add all the eventid's appropriately or if it could do it magically itself.

look into the field properties, if the field has the autoincrement enabled you can just set NULL as id and it'll use the highest free id

I believe it has autoincrement enabled for the eventid. Yes.

Sweeet! Thanks, Xenon. It worked like a charm.

Ok just another question that would build on this one. When I wanted to query for that information to echo it out for whatever and I set up a query somewhat like this:

PHP Code:

$results = mysql_query("select * from table") 


Also if I didn't want everything would I just take out the star and insert the fields I wanted. And what would be the sentax if I only wanted say the username and password from the table.

Sorry for the all questions I'm just very interested.

PHP Code:

$results = mysql_query("SELECT username, password FROM table"); 


btw, whats up with the quote boxes?
