Hi,
I have a column 'id' within a table :
CREATE TABLE `reference` (
*`*id*`* smallint(5) unsigned NOT NULL auto_increment,
`study_name` text,
`author` text NOT NULL,
`date` date NOT NULL default '-00-00',
`reference` varchar(250) NOT NULL default '',
`title` varchar(250) NOT NULL
It looks from googling as though I need to drop all foreign key
constraints on this column, perform the change and then reestablish the
foreign keys. Could anyone confirm or advise of a better solution?
That is the way ! :)
You need to drop the constrains...
Alter `reference` and make `id` INT

Hello,
Are there any plans to implement foreign keys with deferred integrity
constraint checking in the InnoDB storage engine in a future release of
the MySQL Server?
Many thanks,

Put in your script:

mysqldump dumps tables in alphabetical order.

Hi,
I have two innodb tables produced as show below

`omim` varchar(20) default NULL,

One thing that stands out is the data types are different sizes.

Hello list!
I'm having a bit of trouble getting foreign key constraints to work.

Here's what I got:

Table: conn
Create Table: CREATE TABLE `conn` (

First of all the referenced key must be on PRIMARY KEY.
But I've seen in your table definition a quite strange thing. You have a
UNIQUE and an ORDINARY key definition on the same field.
Here:
...
UNIQUE KEY `name_id` (`name_id`), - THIS IS THE FIRST DEFINITION
UNIQUE KEY `comp_name`
Heya!
You need an INDEX.
Try doing this first :
alter table ip_name_tbl add INDEX(name_id);
And add then your constraint.
EG
mysql SHOW CREATE TABLE ip_name_tbl\G
*** 1. row ***
Table: ip_name_tbl
Create Table: CREATE TABLE
