One of the columns inputs may be larger than the column is. Wordpress detects this and will not even send the query to the DB.

The Diff there shows a patch for wp-db you can put in to get more information in the last_error message so it will not be empty.

Answer 2

If you want to get the last error and last query you can use this properties of $wpdb object:

$wpdb->last_error 

will show you the last error, if you got one.

$wpdb->last_query 

will assist you with showing the last query (where the error occurred)

I hope this will help you out.

Answer 3

Hopefully, you define global variable = $wpdb.

If your $wpdb not working, and also not showing any error then you must try these three steps.

1. Print your error using with errors functions.

   echo $wpdb->last_error;

   or

   echo $wpdb->show_errors();

2. If no error visible then you must print your last query using with last query function.

   echo $wpdb->last_query();

3. Copy and paste your last query in your Phpmyadmin > Your Database -> Table -> SQL tab, click on Go button, you will definitely get proper solutions(errors) in it.

Maybe your config hides error showing. Have you tried $wpdb->print_error();?
