I don't understand tho -- the & is *not* a special character whatsoever. SQL submitted via JDBC cannot 'interact' with you as you describe below. I just put together a small example for you to try and let me know what it does for you, for me, it prints out:
$ java TestJDBC
str = ben & jerry
import java.sql.*;
class TestJDBC {
static String createTable = "create table test (str varchar2(255) )"; static String dropTable = "drop table test"; static String insertInTable = "insert into test values ('ben & jerry')"; static String selectFromTable = "select * from test";
public static void main(String args[]) throws Exception {
DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());
Connection conn =
DriverManager.getConnection
("jdbc:oracle:thin:@slackdog:1521:oracle8", "scott", "tiger");
Statement st = conn.createStatement(); try {
// drop the table, if it exist
st.executeUpdate(dropTable);
st.executeUpdate(createTable);
st.executeUpdate(insertInTable);
ResultSet rs = st.executeQuery(selectFromTable); while (rs.next()) {
System.out.println("str = " + rs.getString("str"));
}
rs.close();
st.close();
conn.close();
}
}
