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

How To Set Default Values For Timestamp Fields
what is the syntax for specifying the default values for timestamps in MySQL in the CREATE TABLE command? I have 2 timestamps, one for when the record was entered, the other for any subsequent updates. I know that the first timestamp column will be set automatically on updates, but how does the other for creation timestamp get set. My app is not generating the SQL directly so setting the value using the NOW() command is not an option, as the inserts are coming from different timezones I cannot let the clients set their own values.

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)

Datetime And Timestamp As Default
I would like a column created_timestamp to be populated on record creation (and preferably not updatable); and a column updated_timestamp to be populated on record creation, and then automatically updated on any update. should created_timestamp be of type datetime? and updated_timestamp be of type timestamp? and is ordering of the columns an issue (i.e. only the first gets updated)? mysql complains on the following? create table history ( name varchar(20) not null, createdtimestamp datetime not null default current_timestamp, updatedtimestamp timestamp not null, primary key(name) );

Default Current Timestamp Issues
Using MySQL 4.1.7. I have a sole TIMESTAMP column in the table: insert_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP, Looking at the timestamp docs, a query with NULL or empty, should cause the column to use the current time for its default value, but is not automatically updated. However, putting NULL or simply leaving blank in an INSERT query, gives 01/01/0001. Any ideas?

Error #1293: There Can Be Only One TIMESTAMP Column With CURRENT_TIMESTAMP In DEFAULT Or ON UPDATE Clause
I am using MySQL 4.0/4.1 version. And I am trying to add two timestamp columns to a single table. The columns are insert_date and updat_date to capture the date/time the record was initially inserted as well as the date/time the record was last updated respectively. When I try to set one column (insert_date) with a default value of CURRENT_TIMESTAMP and the other column (updat_date) with ON UPDATE CURRENT_TIMESTAMP, I end up getting the following error: #1293 - Incorrect table definition; there can be only one TIMESTAMP column with CURRENT_TIMESTAMP in DEFAULT or ON UPDATE clause Is there any way around this problem?

Need Help - Mysql 5 Default Values
I created a program for mysql 3.23... We launch on tuesday... Problem is we are installing it on laptops and are tech guy installed mysql 5 instead of the version we currently use. In the mysql 3 when you make a query if there is a null value in the query it automatically places the default value into the table. I.E.

Are Default Values Necessary/good?
Any thoughts on whether or not every column should have a default value? phpmyadmin seems to add them to everything, but I'm not sure if they are really necessary in a well structured database. All of the defaults end up being empty strings or 0 so php wont treat that any differently from a NULL value when the data is retrieved, will it? 2 examples: with defaults: CREATE TABLE address ( ID int(11) NOT NULL auto_increment, Street_1 varchar(64) default '', Street_2 varchar(64) default '', Street_3 varchar(64) default '', City varchar(64) default '', State smallint(6) default Ɔ', Country smallint(6) default Ɔ', Zip varchar(8) default '', PRIMARY KEY (ID) ) ENGINE=InnoDB; without: CREATE TABLE address ( ID int(11) auto_increment, Street_1 varchar(64), Street_2 varchar(64), Street_3 varchar(64), City varchar(64), State smallint(6), Country smallint(6), Zip varchar(8), PRIMARY KEY (ID) ) ENGINE=InnoDB;

Date Vs Timestamp
I have a somewhat large table (about 900,000 rows). I regularly need to run many queries against this table and it's is rather slow. Before making any major changes, I wanted to confirm whether the following changes would help. Right now, I run a query like this: SELECT count(*) FROM refer WHERE date >= '$date1' AND date <= '$date2' However, "date" is actually of type timestamp. So I have an index on the field, but it has the same cardinality as the number of rows, as you might expect. I've also heard using a reserved word of 'date' can be a problem, but not sure if that's a performance issue. I think I may occasionally still need this level of granularity for some things, but 99% of the time, I really only need the actual date for my SELECT statements. I'm thinking it might be best to create a field2 that is of type date and use that for the queries, with an index, and drop the index on field1 altogether. The more I think about the more I'm convinced the way I'm doing it now is the reason it is so slow. Can someone please confirm my stupidity?

Timestamp :: Registration Date
As a newbie to MySQL and PHP, I have been able to set up MySQL as test server on my MacOS X and have also succeeded in connecting my test sites registration form to the proper table in MySQL. Everything works fine except getting MySQL to insert the registration date/time automatically as a new record is posted. I have created two "Timestamp"-date columns - the first one for "Change date" and the second for "Registration date". According to what I can gather from reading, this should do the trick, but it doesn't. No date or time is inserted in the registration date field. Can someone explain (in newbie terms) what I am doing wrong and what I should do to make it work? I want the registration date to be filled-in automatically in every new record and then stay unchanged even if other parts of the record are changed.

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?

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?

I am creating a list of all names whose first entry into the table was during a user-specified time frame. I have that working fine. It looks similar to this: SELECT name, MIN(created_at) as `min_time` FROM table GROUP BY name HAVING `min_time` BETWEEN ? AND ? In order to page this list, to display only 20 rows at a time, I need to also count how many names appeared during the time frame. For some reason I can't think of the COUNT() to do that...
