Continuation from this question:
PDO query updating a datetime column not in query
A column in my table called lastLoginDate was being automatically updated even though my prepared statement did not include said column.
Apparently, when I created the new column, a trigger was set.
Upon using the command SHOW CREATE TABLE table_name, I returned the following results:
CREATE TABLE `users_edi` (
`username` varchar(30) NOT NULL DEFAULT '',
`fullname` varchar(50) DEFAULT NULL,
`userlevel` tinyint(1) unsigned NOT NULL,
`ipaddress` varchar(30) DEFAULT NULL,
`email` varchar(150) DEFAULT NULL,
`entrydate` datetime DEFAULT NULL,
`division` varchar(35) DEFAULT NULL,
`password` varchar(32) DEFAULT NULL,
`userid` varchar(32) DEFAULT NULL,
`timestamp` int(11) unsigned NOT NULL,
`job_title` varchar(30) DEFAULT NULL,
`dept` varchar(50) DEFAULT NULL,
`phone` varchar(11) DEFAULT NULL,
`lastLoginDate` datetime DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP, // <-- here
PRIMARY KEY (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
The table is years old. I just created the column and somehow, a trigger was set to it (I guess).
Regardless, I tried to remove it using the following command:
ALTER TABLE `users_edi`
`lastLoginDate` datetime DEFAULT NULL
But I only get the following error:
[Err] 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 '`lastLoginDate` datetime DEFAULT NULL' at line 4
How do I remove this trigger using the ALTER TABLE command or any other command?
ALTER TABLE users_edi MODIFY COLUMN lastLoginDate DATETIME DEFAULT NULL;

While importing a Database file in myPHP Admin I'm getting the following error:
CREATE TABLE IF NOT EXISTS wpcp_2_aiowps_events ( id bigint(20) NOT NULL AUTO_INCREMENT, event_type varchar(150) NOT NULL DEFAULT '', username varchar(150) DEFAULT NULL, user_id bigint(20) DEFAULT NULL, event_date datetime NOT NULL DEFAULT '0000-00-00 00:00:00', ip_or_host varchar(100) DEFAULT NULL, referer_info varchar(255) DEFAULT NULL, url varchar(255) DEFAULT NULL, country_code varchar(50) DEFAULT NULL, event_data longtext, PRIMARY KEY (id) ) TYPE=MyISAM AUTO_INCREMENT=1 MySQL said: Documentation #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 'TYPE=MyISAM AUTO_INCREMENT=1' at line 13
How can I solve this and import the data successfully without any errors
Note
The older TYPE option was synonymous with ENGINE. TYPE was deprecated in MySQL 4.0 and removed in MySQL 5.5. When upgrading to MySQL 5.5 or later, you must convert existing applications that rely on TYPE to use ENGINE instead.
So you should use
CREATE TABLE IF NOT EXISTS wpcp_2_aiowps_events ( id bigint(20) NOT NULL AUTO_INCREMENT, event_type varchar(150) NOT NULL DEFAULT '', username varchar(150) DEFAULT NULL, user_id bigint(20) DEFAULT NULL, event_date datetime NOT NULL DEFAULT '0000-00-00 00:00:00', ip_or_host varchar(100) DEFAULT NULL, referer_info varchar(255) DEFAULT NULL, url varchar(255) DEFAULT NULL, country_code varchar(50) DEFAULT NULL, event_data longtext, PRIMARY KEY (id) )ENGINE = MyISAM ;
I have the following SQL query
CREATE TABLE IF NOT EXISTS `Log` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`customer_id` int(11) unsigned NOT NULL,
`request_xml` BLOB NOT NULL,
`response_xml` LONGBLOB NOT NULL,
`timestamp_process_end` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
`timestamp_response` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`id`)
);
could someone see any mistakes? Because it gives me a SQL Error when I run the code on server. But on localhost works without any problems (or phpmyadmin)
And btw this works on the server:
CREATE TABLE IF NOT EXISTS `lang` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`language` varchar(2) COLLATE utf8_unicode_ci NOT NULL UNIQUE,
PRIMARY KEY (`id`)
);
that is written in the same style. Any remarks?
LE: Mysql Ver 14.14 Distrib 5.1.73
In the end, the problem was that on the remote server I couldn't have two DEFAULT CURRENT_TIMESTAMP, as stated here mysql link, but this is wired that on the localhost worked.
I am getting the following error message when trying to run some sql code in my 5.5.35-MariaDB. Please can someone help me understand what is wrong?
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 'CREATE TABLE IF NOT EXISTS action_recorder ( id int(11) NOT NULL AUTO_I' at line 1
My code is below:
CREATE TABLE IF NOT EXISTS `action_recorder` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`module` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`user_id` int(11) DEFAULT NULL,
`user_name` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,
`identifier` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`success` char(1) COLLATE utf8_unicode_ci DEFAULT NULL,
`date_added` datetime NOT NULL,
PRIMARY KEY (`id`),
KEY `idx_action_recorder_module` (`module`),
KEY `idx_action_recorder_user_id` (`user_id`),
KEY `idx_action_recorder_identifier` (`identifier`),
KEY `idx_action_recorder_date_added` (`date_added`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=23 ;
Please can someone help me resolve this? Thanks!
You're missing the closing parenthesis. The one at the end is only for the key idx_action_recorder_date_added, but you need another one to close the whole table definition.
Also, I think you shouldn't use those normal single quotes. They are for strings. Use backticks or omit them altogether.
Since the "near..." mentions 'CREATE...', the error is either the CREATE or what immediately precedes it. I vote for the latter -- Look at what have right before it.
This is the query I have used for creating the table
CREATE TABLE IF NOT EXISTS `logging_api_request_js` (
`id` int(30) unsigned NOT NULL AUTO_INCREMENT,
`log_message` longtext,
`level` varchar(10) DEFAULT NULL,
`ip_address_merchant` varchar(45) DEFAULT NULL,
`ip_address_customer` varchar(45) DEFAULT NULL,
`creationTime` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
`updateTime` timestamp NULL DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=11
It showed an error Incorrect table definition; there can be only one TIMESTAMP column with CURRENT_TIMESTAMP in DEFAULT or ON UPDATE clause
When I googled I saw that in the mysql 5.6. version this issue / restriction has been took off.But i wont be able to upgrade mysql right now.
Is there any work around for this,whith out changing the table structure to dump this using mysql?Please help.Im having little knowledge about the db operations.Do help.Thanks
You could remove ON UPDATE CURRENT_TIMESTAMP and create trigger.
DROP TRIGGER IF EXISTS `update_logging_api_request_js`;
DELIMITER //
CREATE TRIGGER `update_logging_api_request_js` BEFORE UPDATE ON `logging_api_request_js`
FOR EACH ROW BEGIN
SET NEW.updateTime = NEW.creationTime;
END
//
DELIMITER ;
Hi any one please help i have a contact table in which i can Insert,Delete,Modify database using PHP web pages....but only current changes will be updated to database. what i want is how i can maintain history of database...
Is there any tutorial for this using (PHP/MYSQL).
I tried creating version of MySQL table for patient... how to proceed further.
CREATE TABLE IF NOT EXISTS `contact` (
`name` varchar(30) NOT NULL,
`phone` varchar(12) NOT NULL,
`mobile` varchar(12) NOT NULL,
`email` varchar(30) NOT NULL,
`address` text NOT NULL,
`conid` int(11) NOT NULL AUTO_INCREMENT,
PRIMARY KEY (`conid`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=4 ; # MySQL returned an empty result set (i.e. zero rows).
CREATE TABLE IF NOT EXISTS `contactversion` (
`name` varchar(30) NOT NULL,
`phone` varchar(12) NOT NULL,
`mobile` varchar(12) NOT NULL,
`email` varchar(30) NOT NULL,
`address` text NOT NULL,
`conid` int(11) NOT NULL,
`revision_id` int(11) AUTO_INCREMENT,
type ENUM('INSERT', 'UPDATE', 'DELETE') NOT NULL,
`change_time` DEFAULT current_timestamp,
PRIMARY KEY (`revision_id`)
);
what to do next....
When running the queries to contact, just simply run this right before to take the current contact and copy it in your revision table...
"INSERT INTO
contactversion (name,phone,mobile,email,address,conid,type)
SELECT
name,phone,mobile,email,address,conid,'".$type."' as type
FROM contact
WHERE conid='".$conid."'"
Both tables will require to be identical, with contactversion having type and change_time as additionnal last columns.
It is obvious that this query should be ran before UPDATE and DELETE of the contact table, but after an INSERT. If you are updating multiple contacts with another where clause than the conid, you'll want to consider building the where statement in a variable to use it inside the INSERT's SELECT and the UPDATE/DELETE
While creating contactversions table make sure conid should not be primary key and auto incremented. I hope that is causing the problem.
