使用wpdb-> query的WordPress数据库错误

Question

I have a query that is using $wpdb->query but every time I run it, it doesn't seem to work and is providing me with the following error message:

WordPress database error You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''4'' at line 1 for query SELECT * FROM wp_mytable OFFSET '4'

This is the code that is causing the error:

$query = $wpdb->prepare("SELECT * FROM " . $wpdb->prefix . MY_TABLE . " OFFSET %s", $offset);
$fetch = $wpdb->get_results($query, 'ARRAY_A');

What am I doing wrong here? I've looked at some other questions but nothing seems to be similar to my issue so I don't know what I'm missing.

Answer 1

Offset should be integer not a string. Also offset comes along with limit

Replace

$query = $wpdb->prepare("SELECT * FROM " . $wpdb->prefix . MY_TABLE . "  OFFSET %s", $offset);

with

$query = $wpdb->prepare("SELECT * FROM " . $wpdb->prefix . MY_TABLE . " LIMIT %d OFFSET %d", $limit,$offset);

Not tested.
