I've assigned a coloum called ptmorphraw to rework the post_title value for sorting. However, when I apply the query the replace values come up as null.

Essentially I need to replace the value so the text...Single Stream, Double Stream etc, become
1 Stream, 2 Stream

SELECT CASE WHEN a.post_title LIKE  '%Single Stream%'
THEN REPLACE( a.post_title,  'Single Stream',  '1 Stream' ) 
WHEN a.post_title LIKE  '%Double Stream%'
THEN REPLACE( a.post_title,  'Double Stream',  '2 Stream' ) 
END AS ptmorphraw, a.post_title AS ptmorph, a . * , d . * 
FROM wp_prefix_posts a
INNER JOIN wp_prefix_term_relationships e ON a.ID = e.object_id
INNER JOIN wp_prefix_term_taxonomy c ON c.term_taxonomy_id = e.term_taxonomy_id
INNER JOIN wp_prefix_terms d ON c.term_id = d.term_id
WHERE e.object_id = a.ID
AND a.post_type =  'recyclingbins'
AND a.post_status =  'publish'
AND d.slug =  'steel'
GROUP BY a.id
ORDER BY ptmorphraw ASC

You missed to put an else condition on your case statement

CASE WHEN a.post_title LIKE  '%Single Stream%'
THEN REPLACE( a.post_title,  'Single Stream',  '1 Stream' )
WHEN a.post_title LIKE  '%Double Stream%'
THEN REPLACE( a.post_title,  'Double Stream',  '2 Stream' )
ELSE a.post_title
END AS ptmorphraw,

Brilliant! Knew it had to be something silly. Been staring at the query too long.
Thanks.
