java jdbc ms 访问 "Syntax error in UPDATE statement"

Question

我正在尝试更新我的数据库，但我的代码中出现了一些语法错误。请帮助。我尝试将其更改为“st.execute(statement);”和“st.executeUpdate(声明)；”但错误仍然存​​在。 这是我的代码...

public void editBook(String inputTitle, String[] newBookInfo)
{
    boolean result = false;
    try
    {
        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
        con = DriverManager.getConnection("jdbc:odbc:database");
        st = con.createStatement();
        rs = st.executeQuery("select * from library");

        while(rs.next())
        {
            if(boyerMoore(rs.getString("Title").toLowerCase(), inputTitle.toLowerCase()))
            {
                isbn = rs.getString("ISBN");
                statement = String.format("UPDATE library SET ISBN = '%s', Title = '%s', Author = '%s', Publisher = '%s', Published Year = '%s', Available Copies = '%s', Total Copies = '%s', WHERE ISBN = '%s'", newBookInfo[0], newBookInfo[1], newBookInfo[2], newBookInfo[3], newBookInfo[4], newBookInfo[5], newBookInfo[6], isbn);
                st.executeQuery(statement);
                rs.close();
                st.close();
                con.close();

                JOptionPane.showMessageDialog(null, "Edit Succes", "Succes", JOptionPane.PLAIN_MESSAGE);
                result = true;
            }
        }

        if(!result)
            JOptionPane.showMessageDialog(null, "\"" + inputTitle + "\"  not Found in the Library", "Error", JOptionPane.ERROR_MESSAGE);
    }
    catch(Exception ex)
    {
        ex.printStackTrace();
    }
}

这是完整的堆栈跟踪..

Answer 1

将包含空格的字段名称括起来:[Published Year]； [可用副本]； [总份数]。无论您是继续像以前一样构建 UPDATE 语句还是切换到参数查询，您仍然必须将这些名称括起来。

如前所述，丢弃 WHERE 之前的逗号 ...

[Total Copies] = '%s', WHERE ISBN
                     ^

如果在进行这些更改后出现“类型不匹配”错误，请检查目标字段的数据类型。目前您的声明正在为这些字段提供文本值。如果有数字而不是文本，请消除更新值周围的单引号。
