(split element column into ElementType and ElementNumber column in the hopes it might help)

Have tried various sub-selects but have not found the secret.

Could do some looping in PHP but hope there is a more elegant sole single MySQL query approach.

There is other columns like location involved so trying to keep it clean.

Here's how I'd do it:

SELECT des.Response AS Name, val.Response AS Value
FROM MyTable AS des JOIN MyTable AS val USING (ElementNumber)
WHERE des.ElementType = 'EntryDes' AND val.ElementType = 'EntryVal';

Use:

  SELECT MAX(CASE WHEN t.elementtype = 'EntryDes' THEN t.response END) AS Name,
         MAX(CASE WHEN t.elementtype = 'EntryVal' THEN t.response END) AS Value,
    FROM YOUR_TABLE t
GROUP BY t.elementnumber

You might want to keep elementnumber as a column, in case you need to ensure order.
