如题,require "mysql"是会出错的,但 require "mysql2" 却是正常的,还是 DBI接口是不是不支持 mysql2 ? 连接都连接不上
下面是例子:
require "dbi"
dbl=DBI.connect("DBI:Mysql:mytext:localhost","tadesmysqldb","123321")
if dbl
puts "连接成功"
else
puts "连接失败"
end
报错结果:
dbi.rb:300:in `block in load_driver': Unable to load driver 'Mysql' (underlying error: uninitialized constant DBI::DBD::Mysql) (DBI::InterfaceError)
知道的朋友告诉下,mysql2下先多mysql的方法都不能使用,那DBI也不能使用了 ?
