I don't see ORDER BY in your statement.

Also, I suggest to add aliases to all columns - it is a good practice to use aliases when you use more than 1 table in your select statement.

>>>Hi all,
>>>the code below works but I need to add in an order by field1, field2 but I can't get it to work, I get an order by error. I've tried a simple order by command but no joy, also tried moving between engine behaviour 70/80/90 with no luck. Any help appreciated.

>I am toying with the idea of a secondary select on the result, but I'd rather do the job in 1 query as I have 5 such queries to do and they are looking at reasonably large data sets, so better off not running commands that I don't have to.
>The error I get back is "SQL: Order by clasue is invalid", this is for engine behaviour set to 70 or 80. If I set it to 90 I get a syntax error and then this error, however I think that the engine behaviour 90 syntax error is not related to the order by.

If it's not broken, fix it until it is.
