java - Search a table with the result of another search in servlet -

-

i have table table1 2 fields id , shift , table table2 3 fields id, name, surname. field id same primary key in both tables.
in servlet want select id's have shift != noon. write

resultset rs = stmt.executequery("select id table1 shifts!=noon");

so have gather records in rs. now, how can search through second table in order select records id's found in 1st look?

you need join:

resultset rs = stmt.executequery("select t2.*                                    table1 t1                                   join table2 t2                                   on t1.id = t2.id                                   t1.shifts <> 'noon'");

look here:

http://www.w3schools.com/sql/sql_join.asp

also need enclose strings noon inside single quotes 'noon', , best use <> instead of != standard sql , more compatible other databases.
