問題1
Consider the following database table: Inventory Table
*Item_ID, Integer: PK
*Item_name, Varchar (20)
*Price, Numeric (10, 2)
*Quan, Integer
Consider the following method that updates the prices in the Inventory table:
public static void updatePrices{ // #1: missing line
Connection con) throws SQLException {
// #2: missing line
PreparedStatement updatePrices = con.prepareStatement (updatePricesString);
// #3: missing line { // #4: missing line updatePrices.executeUpdate(); } }
This method us missing four lines, which group of lines complete this method?

問題7
Given the code fragment:
try {
String query = "SELECT * FROM Employee WHERE ID=110";
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(query); // Line 13
System.out.println("Employee ID: " + rs.getInt("ID")); // Line 14
} catch (Exception se) {
System.out.println("Error");
}
Assume that the SQL query matches one record. What is the result of compiling and executing this code?
