sql - Using EXCEPT operator on MySql 5.1 version -

i have 5.1 mysql version on server. trying perform query:

select file_name words_db word_name=" . $element . " except select file_name files_db display=0

i getting error:

error: have error in sql syntax; check manual corresponds mysql server version right syntax utilize near 'except select file_name files_db display=0' @ line 4

can tell me how can perform query in alternative form?

thank you, max.

as far know mysql not back upwards theexceptoperator. seek instead:

select file_name words_db word_name=" . $element . " , file_name not in ( select file_name files_db display=0 )

you utilize either correlatednot existsor aleft join. don't utilize mysql much can't performs best.
