Btrieve/普及数据库和Ruby [英] Btrieve/Pervasive db and Ruby

问题描述

是否有任何解决方案可用于Ruby级别的Btrieve/Pervasive数据库?有宝石吗?也许有人对这种事情有一些经验?

Is there any solution to work with Btrieve/Pervasive db from Ruby level? Any gem? Maybe somebody have some experience with such a thing?

或者通过Jruby使用一些Java库?我从没用过Jruby

Or maybe use some Java libs through Jruby? I've never used Jruby

推荐答案

@kell我使用了jruby和JDBC Pervasive驱动程序. 简单的例子:

@kell I used jruby and JDBC Pervasive driver. Simple example:

require "java"
module JavaSql
  include_package "java.sql"
end
pervasive_driver = Java::JavaClass.for_name("pervasive.jdbc.PervasiveDriver")
conn = JavaSql::DriverManager.getConnection("jdbc:pervasive://host/database","master","")
stmt = conn.createStatement
rs = stmt.executeQuery("select count(*) as class_count from class")
while (rs.next) do
  puts rs.get_string("class_count")
end
