Query sql doesn't appear correct..

Question

Hi,
I use from my bean the following request:
req="SELECT * FROM FIELD;";
I get a full resultset
Whereas if i use this request:
req="SELECT * FROM FIELD WHERE(LANGUAGE_FIELD="+lang+");";
I get an empty request whereas in MS ACCESS in mode sql when i type this request I get responses!!
Did someone have an idea??

Answer 1

In fact my LANGUAGE_FIELD is a String
I understand the problem but i didn't dixed it for the moment:
when i use the request:
req="select * from FIELD where(LANGUAGE_FIELD="+lang+");"
i receive:
select * from FIELD where(LANGUAGE_FIELD=french);
whereas LANGUAGE_FIELD is a string so i want get:
select * from FIELD where(LANGUAGE_FIELD="french");
I'm sure some people should have the response, and it would really help me!
