Merge issue

[Guerlot]

If I have this line in a PHP page:

$result = mysql_query("SELECT value1,value2,value3 FROM $table ORDER BY value1");

Is there a way to merge the content of the 3 columns into one (let's call it value4) and order the results with that new value?

somebody told me about a "concat" function but I'm not sure about it

you can use concat:

Code: Select all

SELECT concat(`field1`,`field2`,`field3`) as `workname` FROM `sometable` ORDER BY `field1`;


this will return all records from the table and only one column named "workname" wich is field1 + field2 + field3.
