Trouble accessing the database

Question

Hi, am new to java and I am having trouble accessing my database. I have the following code
import java.sql.Connection;
import java.sql.Driver;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.CallableStatement;
import java.sql.ResultSet;
private static boolean verifyInDB(String username, String password){
boolean allow = false;
try {
Driver d =(Driver)Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
conn = DriverManager.getConnection("jdbc:odbc:SITSDB");
queryStr = "SELECT username,\"password\" FROM WebAppUsers WHERE username=" + "'" + username + "'" + "AND password=" + "'"+ password + "'" + "AND archive = 'no'";
myQuery = conn.prepareCall(queryStr);
//myQuery.setString(1, username);
//myQuery.setString(2, password);
rs = myQuery.executeQuery();
if(rs.next())
allow = true;
catch (Exception e) {
System.out.println("Login::verifyInDB: Error Getting Connection: " + e.toString());
System.out.println("Login::verifyInDB: QUERY: " + queryStr);
e.printStackTrace();
finally{closeConn();}
return allow;
I'm almost positive the code it is right however I get an error trying to connect to the database
Login::verifyInDB: Error Getting Connection: java.sql.SQLException: [Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 'WebAppUsers'.
Login::verifyInDB: QUERY: SELECT username,"password" FROM WebAppUsers WHERE username='akabeera'AND password='avenash'AND archive = 'no'
java.sql.SQLException: [Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 'WebAppUsers'.

To be clear when you say the command works in query analyzer. Is this the exact string that you are running in query analyzer?
SELECT username,"password" FROM WebAppUsers WHERE username='akabeera'AND password='avenash'AND archive = 'no'This exact string (the SELECT) looks syntactically incorrect to me, but that doesn't mean your database SQL parser cannot handle it I guess (lack of spaces between quotes keywords), and I'm not sure about the double quotes, but I'm kind of an Oracle guy and all of this could be OK, it just seems messy if nothing else.
I would recommend using first, a type 4 driver if at all possible (not the JDBC/ODBC bridge), and second To avoid much of this messiness, you should whenever possible use a PreparedStatement rather then Statement for this type (and most types) of queries.
