Question

我正在使用SQL Server 2018和JDK 8.0以及NetBeans。连接到SQL Server时，出现img中所示的SQL异常 enter image description here

我正在使用以下代码：

try{
    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

    //Connection establishment
    Connection con=DriverManager.getConnection("jdbc:sqlserver//DESKTOP-CU5U75J\\SQLSERVER1;","","");
    //Statement Object
    Statement st=con.createStatement();
    //For DML use executeUpdate method of Statement Class
    st.executeUpdate("insert into Employee (Employee_Id, Employee_Name) values ("+Integer.parseInt(idTF.getText())+","+nameTF.getText()+")");
    //Commit Statement
    con.commit();

    JOptionPane.showMessageDialog(this, "Message", "The Data is Entered", JOptionPane.INFORMATION_MESSAGE);

} catch (ClassNotFoundException ex) {
    Logger.getLogger(Employe.class.getName()).log(Level.SEVERE, null, ex);
} catch (SQLException ex) {
    Logger.getLogger(Employe.class.getName()).log(Level.SEVERE, null, ex);
}

您在jdbc网址中错过了冒号'：'

 Connection con=DriverManager.getConnection("jdbc:sqlserver://DESKTOP-CU5U75J\\SQLSERVER1;integratedSecurity=true","","");

应该是jdbc:sqlserver//DESKTOP-CU5U75J\\SQLSERVER1;的是jdbc:sqlserver://DESKTOP-CU5U75J\\SQLSERVER1;

此外，我建议您使用PreparedStatement插入您的记录。

String sql="insert into Employee (Employee_Id, Employee_Name) values (?,?)";
PreparedStatement stmt=con.prepareStatement(sql);
stmt.setInt(1, Integer.parseInt(idTF.getText()));
stmt.setString(2, nameTF.getText());
stmt.executeUpdate();
