Default For The Type SET
I've created a database with a field of the type SET. Something like this:
SET('choice1','choice2','choice3').
The default choice is the empty ('') string. Do I have to also define the empty string in the set like this SET('choice1','choice2','choice3','') or is this not necessary?

Date Type Default Value
I would to give the CURDATE() value to a date field as null value. I wrote: sql_fecha` date NOT NULL default 'CURDATE()', and I get : Error #1067 - Invalid default value for sql_fecha I take off the () and got the same result. I also cast the expression as : CAST( CURDATE() AS DATE) and the same error.

Default Table Type On MySQL 5
I seem to recall reading somewhere that InnoDB was the default table type for MySQL 5. Yet when I did a 'show table types' it indicated that MyISAM was the default type since version 3.

I Need To Convert Date Type To String Type
I need to retrieve a Date type data from the database and present the data in my GUI as a String type. I've tried like this : ResultSet rs; Date data; data = (String)rs.getDate("ColumnName"); gui_label.setText(data); but they say inconvertible types... Can someone teach me the way so that I can retrieve Date type data from the database and present it in the GUI as a String type.

Specifying Default ''
does specifying default make the table smaller, like setting_title varchar(32) NOT NULL default '', instead of setting_title varchar(32) NOT NULL, make the entire row smaller, instead of a blank 32?

Bad? Id Int(11) DEFAULT '0'
I'm trying to install the authlib module that's required for the open-source iOutliner web-based outliner (http://ioutliner.com), but it fails halfway through when creating the tables: //Bad! /* SQL Error: Invalid default value for 'id' */ $query = mysql_query("CREATE TABLE authlib_data ( id int(11) DEFAULT '0' NOT NULL auto_increment, name text NOT NULL, email text NOT NULL, age int(3) DEFAULT '0' NOT NULL, sex text NOT NULL, school text NOT NULL, PRIMARY KEY (id) )"); //Bad! /* SQL Error: Invalid default value for 'id' */ $query = mysql_query("CREATE TABLE authlib_login ( id int(11) DEFAULT '0' NOT NULL auto_increment, username text NOT NULL, password text NOT NULL, PRIMARY KEY (id) )"); According to Google, DEFAULT '(0)' seems a legit instruction. What's wrong with this?

MySQL Default Value
When a customer places an order, the database sets the default at "3" which means "not complete" when it is complete and billed, It is assigned a "1" I want to have it be assigned a new number on all future orders, but no not want it to go back and reset every single past order. If I change the default value number in the database, will it only apply to new orders, or will it change every single record to the new default regardless of their current status?

I have a problem with character set client and connection.

[Default] Order
I have a MySQL database with a table that I assumed "by default" would insert records in chronological order - i.e. just add each record to the end of the table. What is happening however is that 'some' records are inserted just somewhere in the file - not at the end of the table. I can tell this because there is a date field in the table. How do records get added to a database? by key, index, ???? Is there some way to force a record to be added to the bottom of the table? Key info about the table: . there is not a primary key. . there are 3 index's

Default Autocommit=0?
Is there any way I can set up mysql client so that the default value for autocommit is 0? This is for when I'm running the command line client on linux/windows or the Query Browser on windows. I would feel much more comfortable that I'm not going to accidentally put in the wrong where clause and update or delete a bunch of records. I like to use the number of rows affected by my query as a double-check that I've done what I intended to do, and then commit it. I've searched around but could not find any mention of this issue -- all of the postings on autocommit that I found have to do with accessing mysqlserver from a program such as java or PHP.

DATETIME - Set Default Value
I have a database table (MYSQL v5.0.67) in which I store several date fields. I have set these all to be not null and to have a default value of '0000-00-00 00:00:00' e.g. `last_login` DATETIME NOT NULL DEFAULT '0000-00-00 00:00:00', However when I run my create database script (generated from a schema design in MYSQL Workbench) it complains as follows: Error Code : 1067 Invalid default value for 'last_login' I leave it as nullable with no default value and run the script to create the table which works fine. I can then use a tool like SQLyog to alter the table generated and set this to be not null with a default of 0000-00-00 00:00:00 and it is happy to alter the table. Obviously this is not ideal and it should work straight from the script.

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.

NOT NULLs With Default
I'm cleaning up a database but I see this all over the MySQL world. I understand that having defaults speeds things up. But what I don't understand is why someone would make a field NOT NULL and then put a null default in it? This makes no sense to me at all. Is this the fault of using phpMyAdmin to create tables? Here's a sample: CREATE TABLE `listnames` ( `id` int(11) NOT NULL auto_increment, `list_name` char(30) NOT NULL default '', `display_name` char(100) NOT NULL default '', `active` char(3) NOT NULL default '', `last_modified` timestamp(14) NOT NULL, UNIQUE KEY `id` (`id`) ) Ok, so you don't want NULLs in your data but there is no default. It's very likely that the data will be wildly differently. So setting a default makes no sense -- or does it? I don't want to drop the default '' if it makes sense & I'm just not getting it.

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?
