How can i deal with this problem

Question

For example, In my database, there are three records:
field : a b c
a.txt c:/a.txt adsfs
b.txt c:/b.txt asdfsf
c.txt c:/c.txt asfdsf
Now I open one file b.txt to check the database whether have the same filename,filepath, hash value.
the results display:
The file: b.txt has not been registered
The file: c://b.txt appears OK
The file: b.txt has not been registered
I want to do is to only shows the results of 'The file: c://b.txt appears OK'. I know the problem is the body of while(rs.next).
is there any best way to conform to my demand
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String url="jdbc:odbc:MD5";
Connection connection=DriverManager.getConnection(url);
Statement statement = connection.createStatement();
String sql="SELECT * FROM MD5";
ResultSet rs = statement.executeQuery(sql);
while (rs.next()) {
if (file.getName().equals(rs.getString("a")))
  if (file.getPath().equals(rs.getString("b")))
  if (m.equals(rs.getString("c")))
    jTextArea2.append("The file: " + file.getPath() +"appears OK"+"\n");
else jTextArea2.append("The file: " + file.getPath() +"has been modified"+"\n");
else jTextArea2.append("The Path for the" + file.getName() +"has been modified"+"\n");
else jTextArea2.append("The file: " + file.getName() +"has not been registered"+"\n");
rs.close();
connection.close();
}

Why not add a WHERE clause to your statment to filter records having the name of the file in the first record. In this case you'd better use PreparedStatement and set the file name as statement parameter
Because now you loop through the entire table for a thing you can deal with at DB level.
And I agree with the others' remarks about those braces ;)
