Why cant i do this?

Question

Hi,
I tried doing this but it's not allowed.
String     HOST = "jdbc:odbc:LogAccess",
             DRIVER = "sun.jdbc.odbc.JdbcOdbcDriver";
     try {
          // connect to db
          Class.forName(DRIVER).newInstance();
          Connection con = DriverManager.getConnection(HOST,"","");
          PreparedStatement ps = null;
          if(TABLE_NAME.endsWith("2002")){
          String query = "INSERT INTO WebLog2002 VALUES(?,?,?,?,?,?,?,?,?,?,?,?,?)";
          }else{
          String query = "INSERT INTO WebLog2001 VALUES(?,?,?,?,?,?,?,?,?,?,?,?,?)";
          ps = con.prepareStatement(query);
          int count=0;
          while(count<=totalRows) {The error is
C:\newclasses\logger3.java:174: cannot resolve symbol
symbol : variable query
location: class logger3
          ps = con.prepareStatement(query);
^
1 error
Tool completed with exit code 1
Why is that so?
Please advise...thanks....
