I am having trouble trying to extract the data from mysql, I have tried every tutorial but still have problems. It only seems to show and loop the title and not the data. Not sure where the problem lies

      $con = mysqli_connect("localhost","root","","oatdistribution");
      $tabsql = "SELECT 'Name', 'LivingCondition', 'OatType', 'NoOfOat', 'Status' FROM OatDis"; 
      $data = mysqli_query($con,$tabsql);
      $total = mysqli_num_rows($data);
      if($total > 0){
        while($row = mysqli_fetch_assoc($data)){
          echo $row['Name']."<br>";

What I have tried:

I have tried multiple types of tutorial online and yet still the same

SELECT 'Name', 'LivingCondition', 'OatType', 'NoOfOat', 'Status' FROM OatDis
Your query isn't selecting any data from the table. Instead, it's returning a set of literal strings for each row in your table.

I suspect you're trying to quote the column names. To do that, you need to use back-ticks, not single quotes:
SELECT `Name`, `LivingCondition`, `OatType`, `NoOfOat`, `Status` FROM OatDis

Fatal error: Uncaught TypeError: mysqli_num_rows(): Argument #1 ($result) must be of type mysqli_result, bool given in C:\xampp\htdocs\PieChart\index.php:8 Stack trace: #0 C:\xampp\htdocs\PieChart\index.php(8): mysqli_num_rows(false) #1 {main} thrown in C:\xampp\htdocs\PieChart\index.php on line 8

this was what came up after changing that

Which simply means there was an error executing the query, which you didn't check for.

Most likely a typo in one of the column names.

Try executing the query directly in workbench to see what the error is.
