I am trying to create a table for a blog and I am attempting to store 2 pictures in it so I resorted to storing it with a LONGBLOB (even though I know that everyone recommends storing it to the filesystem and then adding a link to it in the database but the thing is that there will be only one user and that will be me so there is no reason to overcomplicate it because this will not be a large amount of data or big pictures). Here is the database:
CREATE TABLE posts{
id BIGINT(10) NOT NULL AUTO_INCREMENT,
title VARCHAR(10) NOT NULL,
description VARCHAR(30) NOT NULL,
content VARCHAR(MAX) NOT NULL,
picOne LONGBLOB(MAX) NOT NULL,
picTwo LONGBLOB(MAX) NOT NULL,
PRIMARY KEY(id)
);
The error I get is
ERROR 1064 (42000): 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 'MAX) NOT NULL PRIMARY KEY (id) )' at line 5
I think that I am using the word MAX wrong or maybe there is something wrong with my whole data type or perhaps there is a better approach to this.
I appreciate the help.
Its the inappropriate curly brace { that you are using. Use the following query -
CREATE TABLE posts(
id BIGINT(10) NOT NULL AUTO_INCREMENT,
title VARCHAR(10) NOT NULL,
description VARCHAR(30) NOT NULL,
content VARCHAR(MAX) NOT NULL,
picOne LONGBLOB(MAX) NOT NULL,
picTwo LONGBLOB(MAX) NOT NULL,
PRIMARY KEY(id)
);
Perhaps just a typo.
Look at this. These should be the same () when creating a new table.
'CREATE TABLE posts{'
);
CREATE TABLE posts(
id BIGINT(10) NOT NULL AUTO_INCREMENT PRIMARY KEY,
title VARCHAR(10) NOT NULL,
description VARCHAR(30) NOT NULL,
content VARCHAR(MAX) NOT NULL,
picOne LONGBLOB(MAX) NOT NULL,
picTwo LONGBLOB(MAX) NOT NULL
);
I replaced VARCHAR(MAX) to TEXT and LONGBLOB(MAX) to LONGBLOB. You can try this:
CREATE TABLE posts(
id BIGINT(10) NOT NULL AUTO_INCREMENT PRIMARY KEY,
title VARCHAR(10) NOT NULL,
description VARCHAR(30) NOT NULL,
content TEXT NOT NULL,
picOne LONGBLOB NOT NULL,
picTwo LONGBLOB NOT NULL
);
What I ended up doing was change the VARCHAR value to something really high like VARCHAR(10000) and then leave the LONGBLOB to stand on its own and it worked perfectly. Here is what the code looks like:
CREATE TABLE pages(
id BIGINT(10) NOT NULL AUTO_INCREMENT,
title VARCHAR(10) NOT NULL,
description VARCHAR(30) NOT NULL,
content VARCHAR(10000) NOT NULL,
picOne LONGBLOB NOT NULL,
picTwo LONGBLOB NOT NULL,
PRIMARY KEY(id)
);

I am trying to upload video to S3 and then save it to DB, small videos are working fine they are getting saved and insterted to DB successfully but when it comes to large videos say over 10MB (which is not that large) are uploading to S3 but not saving to DB. Please suggest what is going on here. Because everything looks fine and why I'm getting MySQL server has gone away error for such simple query.

I have this query in PHP which I call from an Android app.
$sql = "SELECT
`asset`.`idasset`,
`asset`.`idlocation`,
`asset`.`asset_barcode`,
`asset`.`asset_number`,
`asset`.`category_name`,
`asset`.`make`,
`asset`.`model`,
`asset`.`serial_number`,
`asset`.`iduser`,
`asset`.`idcost_centre`,
`asset`.`idcondition`,
`asset`.`idstatus`,
`asset`.`latitude`,
`asset`.`longitude`,
`asset`.`asset_description`
from `asset`";
This is the response I receive from the call in Android Studio console:
D/RAW RESPONSE: Notice: Unknown column 'asset.idlocation' in 'field list'
But that field does exist.
Here's the full create statement I reverse copied to clipboard in MySQLWorkbench.
CREATE TABLE `asset` (
`idasset` int(11) NOT NULL AUTO_INCREMENT,
`idlocation` int(11) NOT NULL,
`asset_barcode` varchar(50) DEFAULT NULL,

CONSTRAINT `iduser_fk` FOREIGN KEY (`iduser`) REFERENCES `user` (`iduser`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB AUTO_INCREMENT=93 DEFAULT CHARSET=utf8;
If I run that exact raw query in PHPMyAdmin or MySQLWorkbench it works, but not in PHP.
If I swap around the sequence of the fields I also get the same error with:
`asset`.`asset_description`
`asset`.`latitude`,
`asset`.`longitude`,
But all the other fields are fine.
Strange thing is this query worked a few weeks ago.
Am I missing something?
I don't have any ideas.
Starting to think its a PHP or MySQL setup or something.
Any help would be greatly appreciated as time is not on my side.
Sorry silly mistake, I did point to another DB.
I am creating a dynamic table using mysql query table name should be unique that's why i have added user id to table name.
In Controller:
$last_id = $this->User->getLastInsertID();
//$table_name = 'hello_'.$last_id.'_tutors';
// debug($table_name);
$this->User->query("CREATE TABLE IF NOT EXISTS `post_`.$last_id.`_tutors` (
`id` int(8) NOT NULL AUTO_INCREMENT,
`user_id` int(8) NOT NULL,
`tutor_name` varchar(50) NOT NULL,
`tutor_email` varchar(50) NOT NULL,
`tutor_number` varchar(50) NOT NULL,
`tutor_gender` varchar(50) NOT NULL,
`tutor_address` varchar(100) NOT NULL,
`city_id` int(11) NOT NULL,
`area_id` int(11) NOT NULL,
`matric` varchar(200) NOT NULL,

`diploma` varchar(200) NOT NULL,
`other_education` varchar(200) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=67 ;
");
it gave syntax error like:
Syntax error or access violation: 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 '.75._tutors ( tutor_name

if anyone may help. Thanks in advance.

This is where I'm stuck, I can store the files in a directory and have a file path stored in the database (note: I only store the name of the file in my table for versatility in the future, like if I need to change the path where the files are stored) but what if someone uploads a file with the same name? Should I rename the file to include its ID? Is that even safe to do since it'll be show in the URL on request? Is there a better way, am I going about this horribly wrong? Thank you for your help.
You can try by appending the Unix time stamp at the end of the file name.
like this you can use:
<?php
$date = new DateTime();
$val= $date->getTimestamp();// it will give the unix time stamp
?>
append $val to the end of your file.

Usually the user's IP address will be sent as part of the standard HTTP header information. Certainly I've seen it in IIS logs so it's there. I believe it's in the REMOTE_ADDR server variable.
