ResultSet cannot be resolved to a type
程序代码:
import java.sql.Connection;
import java.sql.Statement;
public class Demo03 {
public static void main(String[] args) {
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver")
.newInstance();
Connection con = java.sql.DriverManager.getConnection(
"jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=books",
"sa", "java");
Statement stmt = con.createStatement();
ResultSet rst = stmt.executeQuery("select * from book");
while (rst.next()) {
System.out.println("<tr>");
System.out.println("<td>" + rst.getString("bookId") + "</td>");
System.out.println("<td>" + rst.getString("bookName") + "</td>");
System.out.println("<td>" + rst.getString("publisher") + "</td>");
System.out.println("<td>" + rst.getFloat("price") + "</td>");
System.out.println("</tr>");
}
rst.close();
stmt.close();
con.close();
}
}执行后,提示这个错误:ResultSet cannot be resolved to a type,谁给点提示
