MFC中 SQL语句格式的的问题

（1）下面是程序中的ＳＱＬ语句：

mSqlStr = "INSERT INTO BORROW (READER_ID, BOOK_ID, BORROW_DATE, B_CLERK_ID) VALUES('";
// mSqlStr = "INSERT INTO BORROW (READER_ID, BOOK_ID, B_CLERK_ID) VALUES('";
mSqlStr = mSqlStr + m_strReaderID;
mSqlStr = mSqlStr + "','";
mSqlStr = mSqlStr + m_strBookID;
mSqlStr = mSqlStr + "','";
mSqlStr = mSqlStr + "', m_BORROW_DATE,'"; //获取系统时间SYSDATE
mSqlStr = mSqlStr + "','";
mSqlStr = mSqlStr + m_strUserID;
mSqlStr = mSqlStr + "')";

（2）下面是数据库中对应表的结构：

（3）下面是程序运行时编译器的错误提示：

（4）谢谢大家了，帮帮忙吧，我是初学者，MFC里面SQL语句搞复杂了就看不懂，简单的还是懂，一复杂看起来就眼睛花了
