I have a large property database and I am trying to get the postcode for a specific property then get the first letter ( the region ) and then count all other properties in my database in that region.
What I am after:
Property postcode is L21 5PU
And I want to display a list of links:
Similar properties in
L1 (4) L2 (5) L23 (27) and so on
Here is where I am upto
$PC = 'L';
PCSearch = mysql_query("SELECT * FROM Property WHERE POSTCODE LIKE '$PC'")
But how do I count each property whose postcode begins with $PC
( L in this case ) and display a list of the postcodes with the number next to them ?
Use group by, something like
SELECT postcode , count(*) as property_count FROM property GROUP BY postcode
That will group all the post codes and give you a property count.
If you want to do partial matching, I believe you will have to run a loop for each partial postcode you want looked up and add a "where" clause in the above query.
.. WHERE postcode LIKE 'L%'
Try this query:
SELECT `postcode`, CONCAT(`postcode`, COUNT(`postcode`)) AS `output`
FROM `Property`
GROUP BY `postcode`
The column output
should now contain what you need.
