mysql_query()插入不了数据解决方案 记录一下，mysql_query()在可查可改的情况下，出现插入不了的数据，我将sql语句复制在cmd下可以插入，但是使用mysql_query()就不行...解决方案就是在mysql_query(“插入语句”)前，写一行mysql_query(mysql, “SET CHARACTER SET GBK”); 方可解决问题。
C++使用mysql判断select查询结果是否为空/mysql_query返回值问题 MYSQL sqlcon; string str = "SELECT * FROM dt_user where user...mysql_query(&(this->sqlcon), str) { return true; } mysql_query的返回值，无效sql语句的时候会返回false，但如果输入sql语句时有效的...，仍然会返回有效的id，换句话说mysql_query无论是否查询值，,只要语法不出问题，都会返回真。...解决思路如下： MYSQL sqlcon; MYSQL_RES * result; mysql_query(&(this->sqlcon), str); result = mysql_store_result...//当mysql_fetch_row返回NULL时，row = NULL 这个表达式的bool为假 { return true; } mysql_store_result()：将mysql_query
