2)rs=st.executeQuery
("select Name,Email from MembersTable where Email like '"+emailidvalue+"' ");

it is not working am i doing in right path..
please help me
thanks in advance.

What error are you getting. elaborate it further.

first of all thanks for repling my post,
actually my requirment is setting email value dynamically.
first i am trying to do in static manar that is i am fixing the email value as String se="sudheer@ca.com"; This is "se" value may sent to the query as a paramater value.
In database also Email is stored like this only(sudheer@ca.com)
query is :
rs=("select Name,Email from MembersTable where Email like '"+se+"' ");
out put : nothing will come .

is it use any regular expression related values in the query please help me ..
thanks in advance..

For starters, use PreparedStatement. Cobbling together SQL statements with string concatenation is fraught with problems.

Secondly, does "se" contain percentage signs? If not, using "like" provides no benefit except to slow down the query, and you should use "=" instead.

Lastly, if a query doesn't return the results you expect, I'd start by running it directly against the DB (with whatever command-line or GUI tool you usually use to interact with the DB).
