这句报错是什么意思没看明白??
请教这句报错是什么意思, Global symbol "$sql" requires explicit package name
我是在WINDOWS下测试的

"strict vars"
This generates a compile-time error if you access a variable that
wasn't declared via "our" or "use vars", localized via "my()", or
wasn't fully qualified. Because this is to avoid variable sui-
cide problems and subtle dynamic scoping issues, a merely local()
variable isn't good enough. See "my" in perlfunc and "local" in
perlfunc.
简单的解决就是 my $sql;

就是说在使用了 use strict 的情况下，你的 $sql 没有声明就使用了。

See "my" in perlfunc

才发现 my 居然是 Perl 5 的 builtin function, 我原来一直以为它是关键字呢 :oops:
