SQL SELECT FROM

Question

I have created a SELECT FROM SQL statement that basically checks if an individual has already registered with my application. The actual search works a treat, with any matches found being ammended to a JTextArea I have created. However, I need to know when a match is not found and am not sure how this is achieved.
When I created an update statement I was able to use the code
int result = statement.executeUpdate(Update);
if(result == 1) //to determine if a match was found.
Can anyone explain how to apply the same logic to this code, please??
try
makeConnection();
Statement statement = connection.createStatement();
query = "SELECT * FROM Manager_Details " +
"WHERE First_Name = '" + details[0] +
"'AND Last_Name = '" + details[1] + "'";
rs = statement.executeQuery(query);
MII.displayMatchedManagers(rs);
statement.close();
connection.close();
catch (SQLException sqlex)
System.out.println(sqlex.toString());
Thanks for any help,

Answer 1

try
makeConnection();
Statement statement = connection.createStatement();
          query = "SELECT * FROM Manager_Details " +
"WHERE First_Name = '" + details[0] +
                              "'AND Last_Name = '" + details[1] + "'";
rs = statement.executeQuery(query);
          MII.displayMatchedManagers(rs);
          statement.close();
connection.close();
the MII.displayMatchingManagers method is below:
try
while(rs.next())
details = "Manager \\ Prediction ID: " + rs.getString("Num") +
"\nFirst Name: " + rs.getString("First_Name") +
"\nLast Name: " + rs.getString("Last_Name") +
"\nAddress: " + rs.getString("Address") +
"\nPostcode: " + rs.getString("Postcode") +
"\nArea Code: " +
What I want to be able to do is display all the matches if one is found,
or call an add method if no match is found. My problem is how to determine if a match has been found???
