I execute a simple insert query, however this insert is done multiple times sometimes unexpectedly. The code for insert is :
$query=$this->db->query("INSERT INTO clientaccesshistory (jobid, clientid,firstname,lastname,clientname,menu,submenu,starttime) VALUES ('$time','$userID','$firstname','$lastname','$clientname','Monitor/Verify', '$this->job_name',current_timestamp() )");
When i look in the database though this information is sometimes there 3 times, sometimes its just once like it is supposed to be. I think this is some issue with connecting to mysql, and then retries till it inserts three times?
I tested the front end to see if the function is actually be called more than once by putting an alert there, but no problem there whatsoever.
Your code almost certainly has to be in a variable loop of some kind. This code, like wonk says, will not add more than one record, ever.
This won't be of much help, but you can try using this-
$arr = array(
jobid => $time,
clientid => $userID,
firstname => $firstname,
lastname => $lastname,
clientname => $clientname,
menu => 'Monitor/Verify',
submenu => $this->job_name,
starttime => current_timestamp()
);
$this->db->insert('clientaccesshistory', $arr);

I would like to use the mariadb INET_ATON() on an insert query with Cakephp Query Builder.
INSERT INTO failed_logins
SET email = 'example#test.com', ip_address = INET_ATON('192.168.0.1'), sent_email = 1;
Then I'd like to retrieve the data with INET_NTOA() in a select query.
SELECT id, email, INET_NTOA(ip_address) AS ip_address, sent_email FROM failed_logins;
How do I use these functions with an insert and select on the Cake Query Builder?
I saw Using SQL functions but couldn't solve my issue.
After a lot of playing around I managed to make it work.
$this->connection->newQuery()->into('failed_logins');
$newIp = $query->func()->inet_aton([$ip]);
$query->insert(['email', 'ip_address', 'sent_email'])->values(
['email' => $email, 'ip_address' => $newIp, 'sent_email' => $sentEmail]
)->execute()->lastInsertId();
Quite complicated and my IDE and PHPStan show me warnings that the function "inet_aton" is not defined.
I would have loved it if in the values() array I could have just done it like ['ip_address' => "INET_ATON($ip)"]. Edit: This is not a good idea see comments. But something similar that stays safe can be done with ->bind() (code snippet below).
Edit: Removed 'literal' from the code snippet (thanks #ndm)
IDE and Analysis Tool - friendly solution
$this->connection->newQuery()->into('failed_logins');
$query->insert(
[
'email',
'ip_address',
'sent_email',
]
)->values(
[
'email' => $email,
'ip_address' => $query->newExpr("INET_ATON(:ip)"),
'sent_email' => $sentEmail,
]
)->bind(':ip', $ip, 'string')->execute()->lastInsertId();
Currently, I have a system to hold main data
1) The email
2) The owner(user_id)
Every time someone uploads , I need to make sure that it doesn't not exist in the system. The catch is as I upload more and more, the amount of time taken to check for duplicate will grow steeply, just like the graph as shown.
Question
1) How do i check for duplicate efficiently?
2) I indexed the user_id and the email should I Fulltext it? I wont be reading the text but will be searching for it as a whole, so index is more logical?
3) I also read about creating Hash combining email&owner id then index the hash. Will it be a big difference from the current method?
4) Last method i thought of was to create a primary key for both email and user_id , once again idk how the performance would turn out.
Please advice.
Code
$exist = DB::table('contact')->where('email', $row['email'])->where('user_id', $user_id)->count();
if($exist < 1){
DB::table('contact')->insert(
['email' => $row['email'], 'name' => $row['name'], 'user_id' => $user_id]
);
}
Use Laravel Validator:
public function store(Request $request)
{
$this->validate($request, [
'user_id' => 'required|unique',
'email' => 'required|unique',
]);
//some logic here
}
Also you should use unique constraint in your database.
I'm new to Drupal.
So I was wondering if you can help me.
I saw a lot of documents regarding the Drupal API mysql thing-y and It's been bugging me that I have to study once more to finish my work done.
And here's the documentation that I'm applying to my problem
Regarding my problem about the INSERT function, I have this table entitled embed
and here is my data from the table embed.
Then on my basic page I'm trying to insert a query.
$id = db_insert("embed")
->fields(array(
'uid' => 1,
'fbp_id' => 22222,
'prom_stat' => 3333,
'status' => 1,
))
->execute();
Instead of inserting a data to the table, it outputs an error like this.
Anyone knows the solution for this stuff? I'm really confused about this right now.
As #steve has suggested in the comment, the issue is not on drupal side but on MySql side. You need to modify your insert code to
$id = db_insert("embed")
->fields(array(
'uid' => 1,
'fbp_id' => 22222,
'prom_stat' => 3333,
'status' => 1,
'prom_id' => 0,
'sweep_stat' => 0,
'sweep_id' => 0,
'comp_id' => 0,
'comp_stat' => 0,
'polls_stat' => 0,
'polls_id' => 0
))
->execute();
Since i can see that your MySql table already contains value, i assume the earlier inserts where done by explicitly providing all values, instead of relying on default values for the field in MySql configuration.
Whenever you have a PDOException you should read it carefully for clues. These kind of errors are really very verbal and gives lots of pointers to resolve the issues. For example in your case,
'prom_id' doesn't have a default value
explains a lot.
I really don't know enough about MySQL queries and it's showing.
I have a custom field set for every post. The custom field stores the posts source URL in a key called "source_url".
I have it working with the below WP_Query parameters, but it's incredibly slow. Keep in mind it's possible to 50+ urls to search for.
So, given an array of source URL's, I want to fetch the matching posts.
For example, here is what I currently have that's slow in WP_Query:
// var_dump of $urls array (this could be 50+ urls)
array(7) {
[0]=>
string(42) "http://www.youtube.com/watch?v=FMghvnqDhT8"
[1]=>
string(42) "http://www.youtube.com/watch?v=RY-yUFpXTnM"
[2]=>
string(58) "http://www.youtube.com/watch?v=nIm2dnyJ1Ps&feature=related"
[3]=>
string(42) "http://www.youtube.com/watch?v=NoCtRQlJAqM"
[4]=>
string(57) "http://holidaycustoms.blogspot.com/2012/08/busy-week.html"

string(42) "http://www.youtube.com/watch?v=DcZvg197Ie4"
[6]=>

}
// Build Media Query
$meta_query = array(
'relation' => 'OR'
);
foreach( $urls as $url ) {
$meta_query[] = array(
'key' => 'source_url',
'value' => $url
);
}
// Get 20 matching posts from a category set by a variable
$args = array(
'post_type' => 'post',
'posts_per_page' => 20,
'orderby' => 'rand',
'cat' => $cat_ID,
'meta_query' => $meta_query
);
$posts = get_posts($args);
What I'm looking to do is replace the above code with a custom query select, which I have read is much faster than WP_Query.
But I don't know enough about MySQL or the WP database to build the custom select query. Can anyone help? Thanks in advance!
In the post you linked yourself, the first reply already states that
[...] the default schema doesn't even have an index on the value column
Which is far more severe a problem than any you would have with a query generator, because without an index the DBMS has to traverse the whole table and compare strings of each field.
Adding an index is fairly easy with an appropriate management tool like PHPMyAdmin. The offending table you will need to add an index to is called wp_postmeta and the field that needs an index is meta_value, and the index type should be INDEX.
Adding an index is transparent and does not affect wordpress other than in performance. It could take some time though since, well MySQL needs to traverse the whole table. Also, because you are indexing string data, the index will be quite big.
You should also try using appropriate structures for your query. You are currently using a big ORed selection with different values but always the same field. There is a construct for just that, and it's called IN.

// Build Media Query
$meta_query = array();
$meta_query[] = array(
'key' => 'source_url',
'value' => $urls,
'compare' => 'IN'
);
// Get 20 matching posts from a category set by a variable
..
(Untested. I actually never did this, Reference)
The performance gain would be negligible compared to adding an index I assume, but your code would become a lot simpler.
$data = array (
'next' => "NOW() + 5",
'interval' => $dom["USER"][0]["STATUSES_COUNT"][0]["data"],
'good' => $good,
'tries' => $p->tries + 1
);
$where = $service->getAdapter()->quoteInto('id = ?', $p->id);
$service->update($data, $where);
to insert something to a database using PHP on zend and mySQL.
The "next" => "NOW()" wont work. I could put the CURRENT_TIMESTAMP as default value, but what i actually want is to insert the timestamp refering this moment, plus some time.
I could rewrite some parts of the program to use pure php dates(instade of pure mySQL dates). Dont know what is best, or what should i do. Do you know how i could make this update work with mySQL doing the timing?
I solved it with the next statement, very usefull:
'next' => new Zend_Db_Expr('TIMESTAMPADD(MINUTE,1,NOW())'),
