MySQL Alter Table Add Field Before or After a field already present

Question

I have this, but it doesn't work:

$query = "ALTER TABLE `".$table_prefix."posts_to_bookmark`              ADD `ping_status` INT( 1 ) NOT NULL BEFORE `onlywire_status`"; 

I appreciate it!

Answer 1

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark`            ADD COLUMN `ping_status` INT(1) NOT NULL            AFTER `<TABLE COLUMN BEFORE THIS COLUMN>`"; 

I believe you need to have ADD COLUMN and use AFTER, not BEFORE.

In case you want to place column at the beginning of a table, use the FIRST statement:

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark`           ADD COLUMN `ping_status` INT(1) NOT NULL            FIRST";
