这是我收到的消息 com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException：您的SQL语法中有错误;检查与您的MySQL服务器版本相对应的手册，以便在#complemc_Id =＆＃39; 1＆＃39;＆＃39;＆＃39;＆＃39;＆＃39;＆＃39;＆＃39;＆＃39;＆＃39;＆＃39;在第1行

            Class.forName("com.mysql.jdbc.Driver");
           Connection conn=DriverManager.getConnection("jdbc:mysql://localhost:3306/optimalcms","root","123456");
                   Statement st=conn.createStatement();
                     PreparedStatement pst; 
                     Object item = RenterRevealeds_ComplexName_ComboBox.getSelectedItem();
                    int value = ((Item)item).getId(); 


            String sql="Select complex.cox_name as 'أسم المجمع',complex.cox_bld_num as 'رقم المجمع',client.clnt_name as 'أسم المسأجر',client.clnt_phone_number as 'رقم هاتف المستأجر',office.ofc_num as 'رقم المكتب',status.status_ofc_status as 'حالةالمكتب'"

            ResultSet rs;
            rs=pst.executeQuery();
            jTable1.setModel(DbUtils.resultSetToTableModel(rs));

Answer 1

不要忘记在单词之间添加空格：

"INNER JOIN complex ON complex.cox_Id = client.clnt_cox_Id"

应该有一个尾随空格，例如：

"INNER JOIN complex ON complex.cox_Id = client.clnt_cox_Id "

还有下一行（以及第一行和第二行）。

有什么想法可以解决吗？
