I'm trying to import my old database but this gave me some errors what makes it impossible im also searching on google for 30 minuts and i can't find any solution?
SQL-query:
CREATE TABLE `UG_blogs` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`catid` int(11) NOT NULL,
`ownerid` int(11) NOT NULL,
`content` text NOT NULL,
`date` datetime NOT NULL DEFAULT TIMESTAMP,
PRIMARY KEY (`id`), KEY id(`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
MySQL meldt: Documentatie
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '
PRIMARY KEY (`id`), KEY id(`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT C' at line 6
The correct default value is CURRENT_TIMESTAMP:
CREATE TABLE `UG_blogs` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`catid` int(11) NOT NULL,
`ownerid` int(11) NOT NULL,
`content` text NOT NULL,
`date` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`id`),
KEY id(`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
The SQL Fiddle is here.
EDIT:
You must be using an old-ish version of MySQL (okay, not that old, just pre-5.6). Well, you can't default a datetime value (without a trigger), so you have to live with a TIMESTAMP value and learn to love the timestamp functions:
CREATE TABLE `UG_blogs` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`catid` int(11) NOT NULL,
`ownerid` int(11) NOT NULL,
`content` text NOT NULL,
`date` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`id`),
KEY id(`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
First solution : change datatype into timestamp like this
CREATE TABLE `UG_blogs` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`catid` int(11) NOT NULL,
`ownerid` int(11) NOT NULL,
`content` text NOT NULL,
`date` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`id`),
KEY id(`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
The problem is : The Timestamp data type has a range of 1970-01-01 00:00:01 UTC to 2038-01-19 03:14:07.
So the second solution is, don't change datetime datatype into timestamp. But you need a trigger to set default value.

I'm developing a listing ads website dedicated to used video games with Laravel 7. I've got a 'GAMES' table and a 'LISTINGS' table as such.
GAMES
CREATE TABLE `games` (
`id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
`title` text COLLATE utf8mb4_unicode_ci NOT NULL,
`slug` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`deleted_at` timestamp NULL DEFAULT NULL,
`created_at` timestamp NULL DEFAULT NULL,
`updated_at` timestamp NULL DEFAULT NULL,
PRIMARY KEY (`id`),
FULLTEXT KEY `fulltext_index` (`title`)
) ENGINE=InnoDB AUTO_INCREMENT=10230 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
LISTINGS
CREATE TABLE `listings` (
`id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
`user_id` bigint(20) unsigned NOT NULL,
`game_id` bigint(20) unsigned NOT NULL,
`name` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`deleted_at` timestamp NULL DEFAULT NULL,
`created_at` timestamp NULL DEFAULT NULL,
`updated_at` timestamp NULL DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `listings_user_id_foreign` (`user_id`),
KEY `listings_game_id_foreign` (`game_id`),
CONSTRAINT `listings_game_id_foreign` FOREIGN KEY (`game_id`) REFERENCES `games` (`id`) ON DELETE CASCADE,
CONSTRAINT `listings_user_id_foreign` FOREIGN KEY (`user_id`) REFERENCES `users` (`id`) ON DELETE CASCADE
) ENGINE=InnoDB AUTO_INCREMENT=412 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
I need to have a paginated list of all the 'GAMES' (not listings) that are being sorted by the 'created_at' column of the latest 'LISTING' attached.
Thanks to #mayankmodi who helped sloving one of the problem, I've updated the below's part to focus on the sorting issue.
If I do this in my gameController:
$games = Game::leftJoin('listings', function($leftJoin)
{
$leftJoin->on('listings.game_id', 'games.id')
->whereNull('listings.deleted_at');
})
->select('games.*', 'listings.created_at')
->orderByDesc('listings.created_at')
->groupBy('games.id')
->with(['listings' => function ($query) {
$query->latest();
}])
->simplePaginate(36);
My games are distincts, but not ordered by last attached listing.created_at.
Do you have any idea how to solve this ?
Ok, I got it to work as expected.
Should anyone can benefit from 4+ hours of trying things out, I'll paste my solution down here.
$games = Game::leftJoin('listings', function($leftJoin){
$leftJoin->whereNull('listings.deleted_at')
->on('listings.game_id', 'games.id');
})
->select('games.*', DB::raw('MAX(listings.id) AS latest_listing'))
->groupBy('games.id')
->orderByDesc('latest_listing')
->with('listings')
->simplePaginate(36);
Thanks for your help !
This question is completely different from similar ones. There is no foreign key in the SQL query. This is a silly error I see when I import the SQL file on remote server. This is the SQL code
CREATE TABLE `locations` (
`id` int(10) UNSIGNED NOT NULL,
`title` varchar(191) COLLATE utf8mb4_unicode_ci NOT NULL,
`created_at` timestamp NULL DEFAULT NULL,
`updated_at` timestamp NULL DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
As you see there is no foreign key, But when I run the following code, it is ok
CREATE TABLE `locations` (
`id` int(10) UNSIGNED NOT NULL,
`title` varchar(191) NOT NULL,
`created_at` timestamp NULL DEFAULT NULL,
`updated_at` timestamp NULL DEFAULT NULL
) ;
If I rename it to something else it is OK too.
CREATE TABLE `locationssss` (
`id` int(10) UNSIGNED NOT NULL,
`title` varchar(191) COLLATE utf8mb4_unicode_ci NOT NULL,
`created_at` timestamp NULL DEFAULT NULL,
`updated_at` timestamp NULL DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
what is wrong?
Just for future references:
Do you have more tables within your database? If so, is there a table that does contain a foreign key connected with the locations table?
I am trying to change the engine for my table "adverts". It does not let me and I get the message that "a foreign key contraint fails". But I removed all foreign keys and SHOW CREATE TABLE gives me this:
CREATE TABLE `adverts` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`id_users` int(11) NOT NULL,
`id_categories_adverts` int(11) NOT NULL,
`type` int(11) NOT NULL,
`status` int(11) NOT NULL,
`duration` int(11) NOT NULL,
`headline` varchar(200) NOT NULL,
`description` text NOT NULL,
`show_contact` int(11) NOT NULL,
`stamp_created` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
`stamp_updated` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=19 DEFAULT CHARSET=utf8
Why can't I change the engine of my table? I am using
ALTER TABLE adverts ENGINE=MyISAM
The problem is that there is at least another table with foreign key to your adverts table. You need to tackle with those foreign key constraints, possibly, by temporarily/permanently removing them.
I have archived some old line items for invoices that are no longer current but still need to reference them. I think I need to create a VIEW but not really understanding it. Can someone help so I can run a query to pull the invoice and then the total of all the line items assigned (no matter what table the items are in)?
CREATE TABLE `Invoice` (
`Invoice_ID` INT(11) UNSIGNED NOT NULL AUTO_INCREMENT,
`Invoice_CreatedDateTime` DATETIME DEFAULT NULL,
`Invoice_Status` ENUM('Paid','Sent','Unsent','Hold') DEFAULT NULL,
`LastUpdatedAt` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`ID`),
KEY `LastUpdatedAt` (`LastUpdatedAt`)
) ENGINE=MYISAM DEFAULT CHARSET=latin1
CREATE TABLE `Invoice_LineItem` (
`LineItem_ID` INT(11) UNSIGNED NOT NULL AUTO_INCREMENT,
`LineItem_ChargeType` VARCHAR(64) NOT NULL DEFAULT '',
`LineItem_InvoiceID` INT(11) UNSIGNED DEFAULT NULL,
`LineItem_Amount` DECIMAL(11,4) DEFAULT NULL,
`LastUpdatedAt` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`LineItem_ID`),
KEY `LastUpdatedAt` (`LastUpdatedAt`),
KEY `LineItem_InvoiceID` (`LineItem_InvoiceID`)
) ENGINE=MYISAM AUTO_INCREMENT=1 DEFAULT CHARSET=latin1
CREATE TABLE `Invoice_LineItem_Archived` (
`LineItem_ID` INT(11) UNSIGNED NOT NULL AUTO_INCREMENT,
`LineItem_ChargeType` VARCHAR(64) NOT NULL DEFAULT '',
`LineItem_InvoiceID` INT(11) UNSIGNED DEFAULT NULL,
`LineItem_Amount` DECIMAL(11,4) DEFAULT NULL,
`LastUpdatedAt` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`LineItem_ID`),
KEY `LastUpdatedAt` (`LastUpdatedAt`),
KEY `LineItem_InvoiceID` (`LineItem_InvoiceID`)
) ENGINE=MYISAM AUTO_INCREMENT=1 DEFAULT CHARSET=latin1
Typically I would just run the following query to get the amount due on the invoices
SELECT
Invoice_ID,
Invoice_CreatedDateTime,
Invoice_Status,
(SELECT SUM(LineItem_Amount) AS totAmt FROM Invoice_LineItem WHERE LineItem_InvoiceID=Invoice_ID) AS Invoice_Total
FROM
Invoice
WHERE
Invoice_Status='Sent'
Also how can I select all the line items from both tables in one query?
SELECT
LineItem_ID,
LineItem_ChargeType,
LineItem_Amount
FROM
Invoice_LineItem
WHERE
LineItem_InvoiceID='1234'
You can use the MERGE Storage Engine to create a virtual table that's the union of two real tables:
CREATE TABLE Invoice_LineItem_All
(
`LineItem_ID` INT(11) UNSIGNED NOT NULL AUTO_INCREMENT,
`LineItem_ChargeType` VARCHAR(64) NOT NULL DEFAULT '',
`LineItem_InvoiceID` INT(11) UNSIGNED DEFAULT NULL,
`LineItem_Amount` DECIMAL(11,4) DEFAULT NULL,
`LastUpdatedAt` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
KEY (`LineItem_ID`),
KEY `LastUpdatedAt` (`LastUpdatedAt`),
KEY `LineItem_InvoiceID` (`LineItem_InvoiceID`)
) ENGINE=MERGE UNION=(Invoice_LineItem_Archived, Invoice_LineItem);
You can use UNION :
SELECT a.* FROM a
UNION
SELECT b.* FROM b;
You just need to have the same number and type of column in your different queries.
As far as I remember, you can add test in sub-queries, but I'm not sure you can order on the global result.

I'm having problems trying to create the following trigger:
CREATE TRIGGER loteria_loterias AFTER UPDATE ON loteria_loterias
FOR EACH ROW BEGIN
UPDATE
loteria_loterias l
JOIN loteria_tipos t
ON l.tipo = t.id
SET
NEW.fecha_fin = NEW.fecha_ini + interval t.duracion hour
WHERE c.cID=NEW.cID;
END
I have this definitions for the tables:
CREATE TABLE `loteria_loterias` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`tipo` int(11) unsigned NOT NULL,
`fecha_ini` datetime NOT NULL,
`fecha_fin` datetime DEFAULT NULL,

CONSTRAINT `loteria_loterias_ibfk_2` FOREIGN KEY (`tipo`) REFERENCES `loteria_tipos` (`id`),
CONSTRAINT `loteria_loterias_ibfk_1` FOREIGN KEY (`ganador`) REFERENCES `tegm_users` (`user_login`)
) ENGINE=InnoDB AUTO_INCREMENT=18 DEFAULT CHARSET=latin1
CREATE TABLE `loteria_tipos` (

`x` int(11) NOT NULL COMMENT '(coordenadas del cartel)',
`y` int(11) NOT NULL COMMENT '(coordenadas del cartel)',
`z` int(11) NOT NULL COMMENT '(coordenadas del cartel)',
UNIQUE KEY `id` (`id`),
KEY `id_2` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=latin1
According to MySQL:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 9
You're missing the ON keyword:
CREATE TRIGGER loteria_loterias AFTER UPDATE ON loteria_loterias
