Im using phpmyadmin and I have a table categories with 4 fields:
-> id
-> id_father_category (I put this with predefined: NULL) and I also put a checkbox Null
-> name
-> content
I want to give null values to my id_father_category field.
But Im having this error:
Warning: #1366 Incorrect integer value: '' for column 'id_father_category field' at row 1
And my field id_father_category stays automatically with value 0, and I dont want that.
Somebody there knows how I can solve this problem?
CREATE TABLE IF NOT EXISTS `categories` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`id_father_category` int(11) DEFAULT NULL,
`name` varchar(64) NOT NULL,
`content` varchar(256) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
Hope this will solve your problem...
This is an addition to #Nirjhor's answer.
ALTER TABLE categories MODIFY id_father_category INT(11) DEFAULT NULL;
or you can recreate the whole thing:
CREATE TABLE IF NOT EXISTS `categories` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`id_father_category` int(11) DEFAULT NULL,
`name` varchar(64) NOT NULL,
`content` varchar(256) NOT NULL,
PRIMARY KEY (`id`) )
ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
Setting the default value to NULL will handle your issue as well as set the field to NULL. One thing to note here is to make sure you don't have some weird index on that field cause that can also create an issue.

I exported the sql from one phpmyadmin db and imported same at another phpmyadmin db.
The create table statement is as follows
CREATE TABLE IF NOT EXISTS `h_stats` (
`Id` int(11) DEFAULT NULL,
`Category` varchar(50) DEFAULT NULL,
`Success` int(11) DEFAULT NULL,
`OutcomeFailure` int(11) DEFAULT NULL,
`ThCount` int(11) DEFAULT NULL,
`OCount` int(11) DEFAULT NULL,
`HDate` varchar(50) DEFAULT '0',
`Count` int(11) DEFAULT '0'
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
The insert sql file also I have exported it as follows
INSERT INTO `h_stats` (`Id`, `Category`, `Success`, `Failure`, `ThCount`, `OCount`, `HDate`, `Count`) VALUES
(13, 'Hits', 31303, 8828, 8893, 30372, '2015-04-07', 40151),
Note :
When I try to insert new rows at the place of id NULL value is coming.
Can anyone suggest me what to change in create table statement.
You need to define the id as primary key and auto-increment .
CREATE TABLE IF NOT EXISTS `h_stats` (
`Id` int(11) NOT NULL AUTO_INCREMENT,
`Category` varchar(50) DEFAULT NULL,
`Success` int(11) DEFAULT NULL,
`OutcomeFailure` int(11) DEFAULT NULL,
`ThCount` int(11) DEFAULT NULL,
`OCount` int(11) DEFAULT NULL,
`HDate` varchar(50) DEFAULT '0',
`Count` int(11) DEFAULT '0',
PRIMARY KEY (`Id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
So when you add null for id, the auto-increment will come in to play and set it the next value in insert.
Note that this will enforce you to have unique value for id so while doing insert leave id into the insert statement. Something as
insert into h_stats (`Category`,`Success` ...) values ( ....);
I am trying to make a revisions page, but when I insert a new revision, it sets the id to 0 instead of 1 more than the last entry, so I can make 1 new revision, but no more. Here is my mySQL code:
("INSERT INTO `revisions` (version, author, content, `date`) VALUES ('".$version."', '".$_SESSION['username']."', '".$content."', '".$date."')");
Edit:
Wow that was embarrassing... I made the table id default 0...
Schema:
CREATE TABLE `revisions` (
`id` int(11) NOT NULL,
`version` varchar(255) NOT NULL,
`author` varchar(255) NOT NULL,
`content` varchar(255) NOT NULL,
`status` int(255) NOT NULL,
`date` varchar(255) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1
:) it saids clearly
id int(11) NOT NULL DEFAULT '0'
it will be inserted as default value 0 if you dont make any value , then it will be 0 as default.
if you wanna be 1 as default then use this
id int(11) NOT NULL DEFAULT '1'
or if you want it be incremented then use this
id int(11) NOT NULL AUTO_INCREMENT
//this will be automatically 1,2,3,4,...values incremented everytime you inseret new value
CREATE TABLE `revisions` (
`id` int(11) NOT NULL AUTO_INCREMENT,
......
you need to set id with auto increment
check out the mysql documentation: http://dev.mysql.com/doc/refman/5.0/en/example-auto-increment.html
You should be adding AUTO_INCREMENT to your id instead. That way, it'll just increment automatically (as the name suggests) each time you insert a row.
CREATE TABLE `revisions` (
`id` int(11) NOT NULL AUTO_INCREMENT,

Here is database structure, generated with red bean php:
CREATE TABLE `attrib` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,

`value` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,

) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=10 ;
CREATE TABLE `attrib_photo` (

`attrib_id` int(11) unsigned DEFAULT NULL,
`photo_id` int(11) unsigned DEFAULT NULL,

CREATE TABLE `photo` (

`filepath` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,

ALTER TABLE `attrib_photo`

ADD CONSTRAINT `attrib_photo_ibfk_2` FOREIGN KEY (`photo_id`) REFERENCES `photo` (`id`) ON DELETE CASCADE;
I'm making manually constructed query:
output of R::debug(); R::getAll($sql);
select filepath
from photo
inner join attrib as attrib4 on attrib4.type = 4 and attrib4.value in ("Dmitry")
inner join attrib_photo as attrib_photo4 on attrib_photo4.attrib_id = attrib4.id and attrib_photo4.photo_id = photo.id WHERE 1=1 LIMIT 0,25
Array ( )
resultset: 0 rows
[]
The result set is empty, but the base contains records, which fall under requirements, and running sql manually in phpMyAdmin shows them.
What's the problem with query, are there any additional debug info I can deal with to solve the problem? Thanks.
Update:
A little detail was missing, in original query I used unicode string for photo attribute search. After some investigations I found that php code works correctly and wrong encoding conversion happens on mysql side. Decision was to change collation of whole database to utf8_unicode_ci. Thanks for attention, and sorry for missing info in question.
I have the following mysql tables:

I created a sphinx configuration file and i can search from PHP. The problem is when i want to search for related videos, a related video must be in the same category as the video i'm searching for. I can do this with MVA and and SetFilter('categories', array(3)) for example, however the total number of matches results is the global one (i need total to display pagination via ajax) not the one in the category.
Any ideas how i can search through videos (documents in sphinx) that are only in a specified category?
Thanks,
Adrian.
You can define for the category ID an integer attribute in Sphinx:
sql_attr_uint = cat_id
And then just add #cat_id=12345 to your query.
i am building a real estate application where in it will store the properties and search it. the property will have different categories like (residential, commercial, industrial or agricultural). based upon the category i want to serailize each and every property listing . for example the property with id 1 belongs to resedential will have the serial code rs_SOMERANDOMUNIQUENUMBER. and for commercial it can be cm_SOMERANDOMUNIQUENUMBER and so on. for this my database table looks like this.
CREATE TABLE IF NOT EXISTS `propSerials` (
`id` bigint(20) NOT NULL auto_increment,
`serial` varchar(50) NOT NULL,
`property_id` int(10) UNIQUE NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
what would be the best possible format to store the serial with the prefix according to category?
thank you
Why dont you add another column that holds category_id and in category table add column with prefixes for that category.
CREATE TABLE IF NOT EXISTS `propSerials` (
`id` bigint(20) NOT NULL auto_increment,
`serial` varchar(50) NOT NULL,
`property_id` int(10) UNIQUE NOT NULL,
`category_id` int(10) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
CREATE TABLE IF NOT EXISTS `propCategories` (
`id` bigint(20) NOT NULL auto_increment,
`category` varchar(50) NOT NULL,
`property_prefix` char(3) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
In query you can:
SELECT CONCAT('prefix_', 'serial');
