Today, I have a issue in $wpdb.

I used

$result = $wpdb->get_var( 
  $wpdb->prepare(
    "SELECT DATE_FORMAT(report_date, '%d-%m-%Y') FROM table WHERE report_id = %d",
     $report_id 
   )
);

The above code not works because of %d in DATE_FORMAT. How i solved this issue in wordpress

From the Codex page for the WPDB class:

[...] the prepare method [...] supports both a sprintf()-like and vsprintf()-like syntax.

Having a look at PHP's documentation for sprintf():

##Example 6 ...

   // notice the double %%, this prints a literal '%' character

So you can use

$result = $wpdb->get_var( 
  $wpdb->prepare(
    "SELECT DATE_FORMAT(report_date, '%%d-%%m-%%Y') FROM table WHERE report_id = %d",
     $report_id 
   )
);

for your purposes.

  • Yea this works, I've done something similar using LIKE in a WHERE clause. Apr 8, 2014 at 20:08
