如何使用java在mySql中的表列中存儲數組值的值

Question

您好，我正在嘗試檢索兩個結果集中的數據。然後，我有店在這兩個結果集到字符串數組，這個過程後，我有我的字符串數組存儲到另一個表如何使這個請你告訴我..

try { 
    Class.forName("com.mysql.jdbc.Driver"); 
    Connection con = (Connection) DriverManager. 
     getConnection("jdbc:mysql://localhost:3306/lportal", "root", "ubuntu123"); 
    PreparedStatement stmt = (PreparedStatement) con. 
     prepareStatement("SELECT * FROM Testi_Testimonial where subject = ?"); 
    stmt.setString(1, search); 
    stmt.execute(); 
    rs = (ResultSet) stmt.getResultSet(); 
    while (rs.next()) { 
     anArray[i] = rs.getString("subject"); 
     System.out.println(anArray[i]); 
     i++; 
     count++; 
    } 
    PreparedStatement stmt1 = (PreparedStatement) con. 
     prepareStatement("SELECT * FROM Testi_Testimonial where subject != ?"); 
    stmt1.setString(1, search); 
    stmt1.execute(); 
    rs1 = (ResultSet) stmt1.getResultSet(); 
    while (rs1.next()) { 
     anArray[i] = rs1.getString("subject"); 
     System.out.println(anArray[i]); 
     i++; 
     count++; 
    } 
} catch (Exception e) { 
    e.printStackTrace(); 
    System.out.println("problem in connection"); 
} 

請告訴我，我應該怎麼我的陣列存儲Temp表？我的「溫度」表有列subject我想存儲myArray到subject列...請告訴我如何做到這一點。

Answer 1

嘗試這種在RS獲得結果集後：

PreparedStatement st = (PreparedStatement) con.prepareStatement("insert into temp values(?)"); 
    i=0; 
    while(rs.next()) 
    { 
     st.setString(1,anArray[i]); 
     st.executeUpdate(); 
     i++; 
    }

您只是想迭代ArrayList中。你有相應的主題列表。

public class TestArrayList { 
    public static void main(String[] args) { 

     /*create two arrayList*/ 
     List<String> tempOneList = new ArrayList<String>(); 
     try { 

      Class.forName("com.mysql.jdbc.Driver"); 
      Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/vijay", "root", "root"); 
      Statement st = con.createStatement(); 

      ResultSet res = st.executeQuery("SELECT * FROM subjecttable"); 

      while (res.next()) { 
       tempOneList.add(res.getString("subject")); 
      } 

      ResultSet resOne = st.executeQuery("SELECT * FROM subjecttabletwo"); 
      while (resOne.next()) { 
       tempOneList.add(resOne.getString("subject")); 
      } 
      System.out.println("temp/List>>--" + tempOneList.size()); 
      for(int i=0;i<tempOneList.size();i++){ 
       System.out.println(tempOneList.get(i)); 
      } 

     } catch (Exception e) { 
      e.printStackTrace(); 
      System.out.println("problem in connection"); 
     } 
    } 
} 

Answer 3

PreparedStatement ps = 
    (PreparedStatement) con.prepareStatement("insert into temp values(?)"); 

j=0; 
while(rs.next()) 
{ 
    ps.setString(1,anArray[j]); 
    ps.executeUpdate(); 
    j++; 
}
