使用Ruby脚本调用Oracle存储过程

        使用Ruby脚本调用Oracle存储过程的示例：
1.首先创建Oracle存储过程test:

SQL> CREATE OR REPLACE PROCEDURE test(p1 in varchar2,p2 out varchar2 ) is 2 BEGIN 3 select p1||" PROCEDURE EXECUTED！" into p2 from dual ; 4 end; 5 / Procedure created

2.再写Ruby脚本，调用存储过程test,脚本内容如下,将脚本保存为：Call_proc_test.rb:

require "dbi"

db_read_str = "BEGIN test(?, ?); END;"
dbh = DBI.connect("DBI:OCI8:TNSDBNAME", "username", "password")
sth_db = dbh.prepare(db_read_str)
sth_db.bind_param(1, "test:",""*50)  # allow for up to 50 chars
sth_db.bind_param(2, " " * 100)      # allow for up to 100 chars
sth_db.execute
str = sth_db.func(:bind_value, 2)
puts str
dbh.disconnect

3.检查Ruby语法错误：

C:>ruby -cw Call_proc_test.rb
Syntax OK

C:>

4.最后执行Ruby脚本：

C:>ruby  Call_proc_test.rb
test: PROCEDURE EXECUTED！

C:>

注释：如果是Windows环境下，大家也可以通过双击Call_proc_test.rb 文件来运行Ruby脚本
