Hi James,
Thanks for your advice.
I've have removed the LEFT JOIN and use SELECT FROM two tables with matching fields. I also verified the output,which were same as the original LEFT JOIN SQL.
I also SELECT only those fields required instead of *.
The performance of the new SQL is much improved.
Thanks for your advice.
Benny
