Hi,
I am trying to create a temp table showing only `wp_ab_staff` that service `wp_ab_locations` with a specific `title`
For example for say `wp_ab_locations` `title` of '2102' only staff with id's 1 & 3 would be displayed?

Any ideas would be appreciated.

Thanks

CREATE TABLE IF NOT EXISTS `wp_ab_staff` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `wp_user_id` bigint(20) unsigned DEFAULT NULL,
  `attachment_id` int(10) unsigned DEFAULT NULL,
  `full_name` varchar(255) DEFAULT NULL,
  `email` varchar(255) DEFAULT NULL,
  `phone` varchar(255) DEFAULT NULL,
  `info` text,
  `google_data` varchar(255) DEFAULT NULL,
  `google_calendar_id` varchar(255) DEFAULT NULL,
  `position` int(11) NOT NULL DEFAULT '9999',
  `visibility` enum('public','private') NOT NULL DEFAULT 'public',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8 AUTO_INCREMENT=7 ;


INSERT INTO `wp_ab_staff` (`id`, `wp_user_id`, `attachment_id`, `full_name`, `email`, `phone`, `info`, `google_data`, `google_calendar_id`, `position`, `visibility`) VALUES

You can CREATE TEMPORARY TABLE with a SELECT query embedded in the CREATE query.  There is an example in this article.  Look for "A TEMPORARY TABLE OF NEARBY ZIP CODES" in the article.

Thanks Ray, but I was trying to work out the SQL code to create the actual table.
The following seems to give me what I need but not sure if it's the correct way to do it?

CREATE TEMPORARY TABLE IF NOT EXISTS wp_ab_staff AS (
SELECT * FROM `wp_ab_staff` WHERE id IN (SELECT staff_id FROM wp_ab_staff_locations WHERE location_id = (SELECT id FROM `wp_ab_locations` WHERE `title` = '2102'))

);

SELECT * FROM `wp_ab_staff`;

Try this..SOLUTION 1

CREATE TEMPORARY TABLE IF NOT EXISTS Temp_wp_ab_staff 
AS 
(
	SELECT staff_id FROM wp_ab_staff_locations l
	INNER JOIN wp_ab_staff ws ON ws.id = l.location_id
	INNER JOIN wp_ab_locations lc ON lc.id = l.location_id
	WHERE lc.title = '2012'
);
SELECT * FROM 'Temp_wp_ab_staff';

Open in new window


or... SOLUTION 2

CREATE TEMPORARY TABLE IF NOT EXISTS Temp_wp_ab_staff AS 
(
	SELECT * FROM 'wp_ab_staff' WHERE id IN (SELECT staff_id FROM wp_ab_staff_locations WHERE location_id = (SELECT id FROM 'wp_ab_locations' WHERE 'title' = '2102'))
);
SELECT * FROM 'Temp_wp_ab_staff';

The general design I would follow goes sort of like this:

1. Write the SELECT query that gives you the exact information you want to put into the TEMPORARY TABLE.  Test it thoroughly so you are comfortable with it.

2. Move the SELECT query into the sub-query of the CREATE TEMPORARY TABLE query, and re-verify that it still collects the desired information.

If I get a chance I will try loading your test data and coming up with the SELECT query, but it's getting late here.  Hopefully by tomorrow!
