Not Able Give Default Value For DATE Field
I would like to specify a default value for "DATE" datatype as a system
date. But i could find from the help tutorial, "default value cannot be
added for a DATE datatype". But i could specify in Oracle. I have found
below statment from the help documents.
"The DEFAULT value clause in a data type specification indicates a default
value for a column. With one exception, the default value must be a
constant; it cannot be a function or an expression. This means, for
example, that you cannot set the default for a date column to be the value
of a function such as NOW() or CURRENT_DATE. The exception is that you can
specify CURRENT_TIMESTAMP as the default for a TIMESTAMP column."
Why cant we use a functions or variable values in date? Is this the
limitation or didnot explore this functionality yet?
Is this limitation applicable for only DATE type or any other datatypes?
I have such a situation to use this "default" feature for a date column
with value as system date.
is there a way to do that?

Now() In Default Value Of Date Field
I have been using the MySQL Administrator in order to create tables and have been unable to set the default value of any date fields to the current date by using the Now() function. When I attempt to do so, I receive the error message: MySQL error number 1067. Has anyone experienced this problem? If so, how do I set the default property of a date field to the current date?

Default Date Format And Date Stamping
1.) If possible, change the default date format from YYYY-MM-DD to MM-DD-YYYY. 2.) Auto "date stamp" a newly created record (e.g. I have a field called "date_posted" and would like that field to be auto-filled with the date upon INSERT). I'm using phpMyAdmin and MySQL version 5.1.30.

Default Value On Date Column
Using MySQL control center, I created a MySQL database table with a column of Date type. It always give the a Default value (0000-00-00) even null is allowed. I tried remove the default value and it comes back by itself. So if I don't supply a value when insert, the default is used. Query IS NOT NULL will not exclude this record. Now, In VB (with ADO/MyOLEDB), I did the exact query trying to filter out the null record. But I still get the record just like in Control Center. BUT, the value on this column is "NULL". How can I leave the Date field as null if no value is supplied?

Form Default Date
I have a MYSql database with an ASP VB form. I set up a text field and set the default value as: <%=date()%> but when I click the button to insert the record it tells me to check the sql error and lists my date field. My MySQL date type is date, not datetime. I am using Dreamweaver MX. How do I set the default date so that it inserts correctly into mysql? Apparently I can't set the default value for the date field in the database structure because I link with an odbc driver.

DATE / TIMESTAMP Default Values
im is having problems with auto inserting date in my table. I dont know what is the default value i will set if column type to DATE. It was succesful though if is use the TIMESTAMP type in the column and is using CURRENT_TIMESTAMP as the dafault value. mysql automatically inserts the current date and time to the database everytime a new record is inserted. The problem with using TIMESTAMP is that i only want the date and not the additional time. Is there a default value I can use for the DATE function instead of using TIMESTAMP? I already tried NOW(), CURDATE(), CURRENT_DATE() to no avail

Setting DEFAULT Value After Creation Of Field
I've been searching all over w3schools to no avail. I have a column whos domain is varchar(6). I want to set the default value to 'active'. I already have a whole lot of values in there. Some are 'active', some are 'closed'. I just figured it would be nice to have a default value in case someone added an entity and didn't specify this particular field. So, how do I set the default value for a column after I've already created and populated the dbase? And are there any better resources on the web than w3schools?

The join gives results while the NOT IN gives 0 results. How come? select cats.id from cats left join items on cats.id = items.catid where items.id is null select cats.id from cats where cats.id not in (select catid from items) btw: what query is the most performant if any? or do you need more info for that?

Give On Condition Higher Priority
I have a system where my pages are built of a bunch of boxes. Each box can have multiple contents, which is displayed att different times. So a box can have a box contents with "begins" = NULL, and "ends" = NULL. At the same time, it can have a box contents with "begins" = 2007-10-01, and "ends" = 2007-11-10. When I select it all, I group on box id, because I just want one box contents. But the problem is that I need the contents which doesn't have begins/ends as NULL to get a higher priority than the once that do. So a user can have one box contents to be displayed all the time, except from 2007-10-20 to 2007-10-21. My current query (it's stripped, I don't use SELECT * ) looks like: SQL SELECT * FROM pages AS p LEFT JOIN pages_boxes AS pb ON pb.page_id = p.page_id LEFT JOIN boxes AS b ON pb.box_id = b.box_id LEFT JOIN boxcontents AS bc ON b.box_id = bc.box_id WHERE ( bc.box_ends > CURRENT_TIMESTAMP OR bc.box_ends IS NULL ) AND ( bc.box_begins < CURRENT_TIMESTAMP OR bc.box_begins IS NULL ) GROUP BY b.box_id But it always just selects the box contents which was inserted first.
