Can't think of suitable query

Question

Hi, I have retrieved an integer in a variable 'n' using request.getParameter command. Now I want to delete first 'n' number of records from a table. What query should I write in PreparedStatement stat=con.prepareStatement(" ");

Answer 1

ah - see- I knew someone would come up with a better solution than my
// pseudocode here
ResultSet rs = statement.execute("SELECT * FROM yourTable");
String[] keys = new String[5];
for (int j = 0; j < 5; j++) {
    if (rs.next()) {
        keys[j] = rs.getString("primaryKey");   
for (int j = 0; j < 5; j++) {
    // preparedStatement is something like "DELETE FROM yourTable WHERE key = ?
    preparedStatement.setString(1, keys[j]);
    preparedStatement.executeUpdate();
}This is what happens when someone who only knows SELECT, INSERT, UPDATE, DELETE has to do SQL work.
