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?

Date/Time As A Default Values For A Table Column
I am new to mySQL, so this question might be simple.I want to add a default value to a column that is the current date/time. I am using the mySQL Administrator and will not allow me to use a function like CURRENT_TIMESTAMP() or NOW() as a default value. I used to do this with other databases (I always add a column to all of my tables called InsertDateTime and UpdateDateTime. It helps to track down data entry problems)

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.

Use Now() As Default Value For A Column
I cannot find any good material on this, and it seems like it should be so easy.

I have two columns in my table, creation_date and last_modified_date. I want the creation_date field to bear the default value of Now(), so that when a row is created the timestamp is there. This value should never change, and should only be set on row creation.

The last_modified_date field I want to change on the UPDATE only.

It seems that this may be possible using the TIMESTAMP type and the default values there but what I read is that they will update everytime a row is altered.

This would be dead-simple if I could just specify Now() as the default value.

Default Value For A Column, When Value Is Not Specified
We have migrated our database from DB2 to MYSQL. In DB2, there is an option like 'GENERATED BY DEFAULT AS IDENTITY' which will cause DB2 to generate unique values for the identity column during insert operations if no value is specified for the identity column. However, if a value is specified for the identity column, DB2 will use it in the insert operation.

In MYSQL, is there an option like this?

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?

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

Date Column Null?
I'm importing a dbf formatted table into mysql. The table has a date column but a lot of the dates are left out. I made sure that the target table's date column is set to 'allow null'.
For some reason, the rows in the source table where the date column is blank get imported as '1/1/0001'. And that doesn't test as NULL either.

I am using navicat as my mysql gui.

Any thoughts about what 1/1/0001 really means and why that happens?

And is there a simple way to convert any appearances of 1/1/0001 to null? I've tried things like update table set arrival_date = null where arrival_date = '1/1/0001' and that runs ok but doesn't work...it reports that it affects '0 rows' so the 1/1/0001 that I am seeing must somehow be actually stored as something other than 1/1/0001.

And I know that 1/1/0001 is outside the allowed date range for mysql ... I'm sure that's a clue but I still can't figure out the answer.

Viewing Date Range Then Adding Column Totals?
this is probably my most complex question to date. Basically i have a table that stores order information for products. What i need to do is:

- Specify a Date range
- Count number of rows in that range
- Get column totals for that range
- Return Array with column totals eg, if the array was named $total, $total['column1'] would be the column 1 total :)

This is a large table with many columns so here is what i had planned:

//OPEN CONNECTION HERE, SET DB
//First query gets date range:
$result = mysql_query("SELECT * FROM D_Orders_Columbus WHERE odate > '" . $startdate . "' AND odate < '" . $enddate . "'");
//now we get number of rows:
$num_orders = mysql_num_rows($result);

After that i get stuck, i need it to ADD the column values together, for this i assume i will need to set the column types to 'SMALLINT' (i dont assume anyone will order 32000 items :p). How can i get mysql to total all the columns that can be (eg. have number types) and then return an array with the totals?
