成员资格提供程序 - update语句中的语法错误

Question

请告诉我以下更新声明中的错误在哪里：

OleDbCommand updateCmd = new OleDbCommand("UPDATE [" + tableName + "]" +
                " SET Password = ?, LastPasswordChangedDate = ?" +
                " WHERE Username = ? AND ApplicationName = ? AND IsLockedOut = False", conn);

错误是

[OleDbException（0x80040e14）：UPDATE语句中的语法错误。]

提前致谢

PASSWORD一词是MS-Access Jet SQL的reserved keyword 如果你想在你的表中使用它，那么你需要用方括号

封装它

OleDbCommand updateCmd = new OleDbCommand("UPDATE [" + tableName + "]" +
            " SET [Password] = ?, LastPasswordChangedDate = ?" +
            " WHERE Username = ? AND ApplicationName = ? AND IsLockedOut = False", conn);
