## Insert a row into the table omitting all values?

Suppose I have a table with a serial as primary key and couple of other columns, that are all nullable. Is there any way to insert a new row in that table by omitting all the columns in the insert clause? Since serial is auto-incremental and can be omitted right? The rest of columns can be null and can therefore be omitted too? So theoretically it should be possible somehow. But is it?

## Insert a node in a binary search tree

The teacher gave us this code that inserts a node in a binary search tree, but I am not sure what the $$z.p = y$$ instruction does. wouldn’t the algorithm work without it?

abr_insert(T, z) //z is the node that must be inserted     {             y = NULL;             x = T.root;             while(x != NULL)             {                     y  = x;                     if(z.key < x.key)                             x = x.left;                     else                             x = x.right;             }             z.p = y; //here is the instruction that I don't understand             if(y = NULL)                 T.root = z;             else if(z.key < y,key)                     y.left = z;             else                     y.right = z;     } 

## MySQL Date insert

I have a date for example in the following format in column A

03/03/2020 01:48:18 pm (Currently Month, Day, Year and 12 hour format for time)

I would like to read the date in Column A and insert into Column B into the following format

2020/03/03/ 13:48:18( Need format Year, Month, Day and 24 hour format)

Would like a query to search for all records in Column A and insert into Column B , row for row

## Confused in how to insert a slack variable in a constrain inequality

According to my understanding , we should put a slack variable to equate an inequality constrain by inserting the slack varaible in the side that is less than the other side , for example if we have 4x+2<2 this will be 4x+2+slack_variable=2 .But here in Wikipedia :
https://en.wikipedia.org/wiki/Slack_variable In the example section , it says the following “By introducing the slack variable y>=0, the inequality Ax<=b can be converted to the equation y-Ax+b = 0” Which means that the slack variable is inserted in the bigger side ! Please some one explain this confusion.

## Translation anchor insert broken (#file_links)

Hello @sven, sorry to bother you again.

It seems when using the #file_links to pull in lines of content, then using translate around the #file_links, SER does not insert the anchor properly and instead breaks the link, it ends up being a giant block of text.

Note: I have tested this without using #file_links (by grabbing a random article and surrounding it with the translate macro) and it works properly.

Here is the code I use to create my article templates:

#trans_en_sk #file_links[example.dat,1,S] #file_links[example.dat,1,S] #file_links[example.dat,1,S] #notrans

The test site/anchor I used in this example (note: only testing in preview mode):

https://www.google.com/#Google

Output of the bug (blurred for text privacy):

You can see the entire bottom part becomes a link. I have now tested this many times, and every time the result is the same. A giant block of text as the link, and the actual anchor not linked at all.

Please let me know if this is preview-bug only, because I’m hesitant to test it on a live site in this situation.

## Select into query, insert fails, but the table is created

I am using SQL Server 2016

I tried to the following query.

SELECT CONVERT(BIGINT, ‘A’) col1 INTO #tmp This query is obviously in error. Because it does not convert. However, the temporary table (#tmp) is created even if the query fails.

Why? I think this is by design, but I want to know.

P.S. PDW (parallel datawarehouse) does not create temporary table.

## Unable to insert two value in two different columns (WordPress database)

So I have made a new input with the name “Anaam”. When users fill in their info in the input, it should go to the database. However, it will not. I have looked at youtube videos to solve this problem. I have also looked for similar questions like this on Stack Overflow. However, this is with a WordPress database, so the inserting code is different then it usually is. Because of that, I could not find good questions on this.

My HTML code:

   <html>       <head>        </head>       <body>         <form action="" enctype="multipart/form-data" method="post">           <input name="file" type="file"/>           <br>           <br>           <input name="Anaam" type="text" placeholder="Albumnaam" class="albumnaam">           <input name="submit" type="submit" value="Upload uw album" />          </form>       </body>     </html> 

As you can see, I have made an input with the name “Anaam”.

My PHP code:

// ... Some data to connect with the remote FTP server, nothing to do with the database  $Anaam =$  _POST["Anaam"];  if ((!$conn_id) || (!$  login_result)) {      echo "Het spijt ons, er is momenteel geen connectie met de server.";     // echo "Attempted to connect to $ftp_server for user$  ftp_user_name";      exit;  } else {      // echo "upload is gelukt"; }    //Only allow zip and rar files to be uploaded $allowed = array('zip', 'rar'); if(in_array($  fileActualExt, $allowed)) { // upload the file (in remote ftp server)$  upload = ftp_put($conn_id,$  destination_file, $source_file, FTP_BINARY); // check upload status if (!$  upload) {      echo "Er is iets fout gegaan, excuses voor het ongemak"; } else {      // insert data in de database      global $wpdb;$  number_of_rows_inserted = $wpdb->insert('wpex_programma', [ 'naam' =>$  fileName,       'Anaam' => "test"      ]);        var_dump($number_of_rows_inserted);  As you can see, I want to insert the values in the database wpex_programma in the column “naam” and the column “Anaam”. In the column “Anaam” I want to insert the value of the variable$ Anaam. Why will it still not work? It does not show any errors. It just never stops loading.

My table structure:

## Universal hashing – insert / search / delete

I don’t understand the highlighted text below in CLRS 3rd Ed.:

What do they mean by “containing $$\mathcal{O}(m)$$ INSERT operations“? What contains them? And why $$\mathcal{O}(m)$$?

## Insert additional links (from project) – inserts duplicate links?

Hi @sven,

I’m not sure if this is working as intended (don’t think so?), but, when you use “Insert X additional links from project,” SER will sometimes re-insert the same link (domain) inside the same article (using the same anchor as the first instance).

Meaning, it doubles up links to a certain domain instead of making all the additional links unique, i.e., X random (unique) links per entry.

Is this supposed to happen? Note: This is on actual submission, not only in preview mode.
