我是Netbeans的新手,現在正試圖建立JDBC連接。我想連接一個MS Access數據庫mis.accdb
與我的java文件ShowData.java
。的ShowData.java
找不到符號executeQuery
import java.beans.Statement;
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class ShowData extends HttpServlet
{
public void doGet(HttpServletRequest request,HttpServletResponse response)throws ServletException,IOException
{
response.setContentType("text/html");
PrintWriter out=response.getWriter();
Connection con=null;
Statement st=null;
ResultSet rs=null;
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
try
{
con=DriverManager.getConnection("jdbc:odbc:mis");
} catch (SQLException ex)
{
Logger.getLogger(ShowData.class.getName()).log(Level.SEVERE, null, ex);
}
st=(Statement) con.createStatement();
rs=st.executeQuery("select * from student");
out.println("<table border='1'><tr><th>Student ID</th><th>Student Name</th><th>Branch</th></tr>");
while(rs.next())
{
int sid=rs.getInt("StudId");
String snm=rs.getString("StudName");
String br=rs.getString("Branch");
out.println("<tr>");
out.println("<td>"+sid+"</td>");
out.println("<td>"+snm+"</td>");
out.println("<td>"+br+"</td>");
}
}
catch(ClassNotFoundException e)
{
out.println("Driver Loading Failed...");
}
catch(SQLException e)
{
out.println("Please Check SQL Query...");
}
}
}
內容這段代碼最初工作沒有NetBeans IDE和現在當我試圖實現它的IDE,它顯示我作爲
cannot find symbol
symbol: method executeQuery(String)
location: variable st of type Statement
請幫我解決就行了rs=st.executeQuery("select * from student");
錯誤這個問題,並且還指導我如何連接到Netbeans中的上述指定的MS Access數據庫mis.accdb
。謝謝
你將需要爲這個JDBC驅動程序,嘗試尋找在這篇文章可能會有所幫助:HTTP://計算器。 com/questions/20007353/connect-to-access-database-in-java-using-netbeans – Aaron
非常感謝。這工作...! –
