如何在不获取throw消息SQLServerException:The statement did not return a result set
的情况下运行查询。我可以在没有结果的情况下运行它吗?我想要的原因只是运行查询并从一个表复制我的值,并通过一个查询将它们添加到另一个表
public void makesales(){
Connection con =getConnection();
Statement st;
PreparedStatement pst = null;
ResultSet rs;
try{
String query= "INSERT INTO Sales (Pro_Id ,Pro_Name,Sales_Quantity,Pro_Price ) SELECT Pro_Id,Pro_Name,Sales_Quantity ,Pro_Price FROM Receipt";
pst=con.prepareStatement(query);
rs=pst.executeQuery();
if (rs.rowInserted()){
JOptionPane.showMessageDialog(null, "copy success");
}else{
JOptionPane.showMessageDialog(null,"error"); }
// if (rs.next()){
//JOptionPane.showMessageDialog(null,"done");
// }else{
// JOptionPane.showMessageDialog(null, "wrong");
//}
}catch (Exception e) { JOptionPane.showMessageDialog(null, e); }
}
以下是想要使用它的人的正确代码。
public void makesales(String query,String message) {
Connection con =getConnection();
Statement st;
try{
st =con.createStatement();
if((st.executeUpdate(query))==1)
{
JOptionPane.showMessageDialog(null,"Data "+message+" Succefully");
}else{
JOptionPane.showMessageDialog(null,"Data Not "+message+ "Error");
}
}catch (Exception ex){
ex.printStackTrace();
}
}
private void ReceiptActionPerformed(java.awt.event.ActionEvent evt) {
String query= "INSERT INTO Sales (Pro_Id ,Pro_Name,Sales_Quantity,Pro_Price ) SELECT Pro_Id,Pro_Name,Sales_Quantity ,Pro_Price FROM Receipt";
makesales(query,"Inserted");
}
