DBI：断开连接-问题 [英] DBI: disconnect - question

问题描述

您会将 disconnect -代码的一部分称为线噪声还是直接保留？

Would you call parts of the disconnect-code as line-noise or would you leave it as it is?

use DBI;

my $dbh = DBI->connect ...
...
...
END {
    $dbh->disconnect or die $DBI::errstr if $dbh;
}

推荐答案

与数据库的显式断开是如果您在完成所有工作后退出程序，则没有严格的必要。但这是一个好主意，尤其是在您已执行多个连接或将要执行多个顺序连接的程序中。

Explicit disconnection from the database is not strictly necessary if you are exiting from your program after you have performed all the work. But it is a good idea, especially in programs in which you have performed multiple connections or will be carrying out multiple sequential connections.
