Question

本人菜鸟，没学过c++，求教vc语句

mSqlStr = "SELECT * FROM CLERK WHERE NAME='";
mSqlStr = mSqlStr + m_strName;
mSqlStr = mSqlStr + "' AND PASSWORD='";
mSqlStr = mSqlStr + m_strPassword;
mSqlStr = mSqlStr + "'";
是什么意思

Answer 1

mSqlStr="SELECT * FROM CLERK WHERE NAME='m_strName ' AND PASSWORD='m_strPassword'"
这里是定义连接数据库时的查询语句，这些你还是从基础做起吧，至少也要学一下C语言基础和SQL语法啦.

Answer 2

字符串链接，拼一个select语句 呵呵 最后mSqlStr值应该是 select * from clerk where name=m_strName and password = m_strPassword
