“set names” vs mysqli_set_charset — besides affecting mysqli_escape_string, are they identical?

由 泪湿孤枕 提交于 2019-11-30 16:45:40
问题 It seems to be common knowledge to use mysql_set_charset / mysqli::set_charset instead of the direct MySQL query set names. The reason often cited is that set names is insecure because the encoding used for mysql_real_escape_string / mysqli::real_escape_string will only be set by a call to mysql_set_charset / mysqli::set_charset . (Another reason cited is that the PHP docs says it's "not recommended" §.) However, is it safe to use the direct MySQL query set names if we use prepared statements

1．mysql_fdw源码克隆 链接：https://github.com/EnterpriseDB/mysql_fdw/releases 选择最新版REL-2_5_1 2．mysql_fdw编译安装 下载来的源码不自带window工程文件，自己新建工程，将源码加入 工程依赖PostgreSQL和mysql, C++编译附加包含目录需要设置相应目录 文件路径自己修改：以我的为例使用的是PostgreSQL9.5.4和mysql5.7.2 C:\Program Files\PostgreSQL\9.5\include C:\Program Files\PostgreSQL\9.5\include\server C:\Program Files\PostgreSQL\9.5\include\server\port\win32 C:\Program Files\PostgreSQL\9.5\include\server\port\win32_msvc D:\MySQL\MySQL Server 5.7\include 链接目录 C:\Program Files\MySQL\MySQL Server 5.7\lib\libmysql.lib C:\Program Files\PostgreSQL\9.5\lib\postgres.lib MYSQL_FDW.def文件（通过模块定义文件导入

Cheapest way to to determine if a MySQL connection is still alive

由 人盡茶涼 提交于 2019-11-28 21:34:33
I have a pool of MySQL connections for a web-based data service. When it starts to service a request, it takes a connection from the pool to use. The problem is that if there has been a significant pause since that particular connection has been used, the server may have timed it out and closed its end. I'd like to be able to detect this in the pool management code. The trick is this: The environment in which I'm coding gives me only a very abstract API into the connection. I can basically only execute SQL statements. I don't have access to the actual socket or direct access to the MySQL
